                             INTRODUCTION


The word “fireworks” as a metaphor, used either to describe the higher
flights of oratory, of literature, or of human strife, whether it be
in Parliament or the Parish Hall, or merely descriptive of domestic
discord, is familiar, even threadbare.

Moreover, the metaphor has generally a humorous flavour; why is this?
Is there anything inherently comic about fireworks? It is true that for
a short season the less critical of the comic papers used the cracker
and squib as pegs upon which to hang the type of joke which depends for
its success on the atavistic human trait of laughing at the misfortune
or discomfort of others, but this is the lowest type of humour which
soon palls upon the mind.

The Stage also has its comedy and clown, yet the mention of the stage
is not a signal for mirth. Can any who have heard the long-drawn Ah-h!
of rapture from many thousand throats, at the bursting of a flight of
shell, or the darting up of the wonderfully tinted rays of the “Magical
Illumination” at the Crystal Palace, maintain that the most dramatic
moment on the stage is more affecting to the spectators?

Pyrotechny is possibly the only art which can compete with nature;
anyone who has seen a first-class firework display will admit that for
impressive grandeur, colour effects, and contrasts of light and shade,
pyrotechny is unapproached.

Pyrotechny paints on the canvas of the sky; and the results are at once
the joy and despair of the artist. Many artists have tried to record
their impressions, but the results have been generally disappointing.
Whistler came near success, but even his wonderful work conveys merely
the dying embers of passed glory. One feels that here has been a
magnificent display, but the scene in its full grandeur is not depicted.

One of the few black-and-white artists who can approach the subject
with some success is Mr. C. M. Padday, an example of whose work is
reproduced in the following pages. His success comes from a careful
study of the subject, both technically and from the point of view of
composition.

That fireworks are popular there is no doubt; no form of amusement is
capable of giving enjoyment to so many people at one time; there is
no entertainment which so appeals to youth and age of all classes and
tastes. And yet it is doubtful if there is an industry concerning which
the public at large is so profoundly ignorant.

To the average onlooker any firework which rises in the air is
a rocket, any that revolve are catherine wheels; both of these
assumptions are incorrect.

What is the average conception of a firework factory? A building, let
us say, in which workmen, with sleeves rolled up, are busily engaged in
shovelling heaps of gunpowder. How many know that a firework factory
consists of dozens of small buildings, the construction of which is
exactly defined by law, separated by spaces also specified by law; that
workmen may not roll up their sleeves in the danger buildings; or that
the amount of gunpowder in each building is strictly limited to a small
quantity? All of these restrictions being enforced with the view, of
course, of limiting the effects of any explosion that may occur.

So far as I am aware, no history of the art has yet been written. It is
true that during the nineteenth century many text-books on pyrotechny
were written, but the historical side of the subject has been generally
represented by a few disjointed remarks in the prefaces.

My object has not been to write a text-book on firework-making, but
rather to trace the art from earliest times, and to give a description
of the development and process of manufacture. For those interested
in the subject, and desiring fuller information, the list of MSS. and
books given in the Bibliography at the end of this volume may be found
useful.

My excuse for adding another volume to the literature of the art is
that I am of the eighth generation of a family of pyrotechnists, whose
work, I venture to claim, has not been without its effect. If I succeed
in interesting, and in some degree enlightening, my readers, I shall
feel I have not written in vain; if I fail, I shall know it is not in
my choice of subject but in my capacity for dealing with it.

                               CHAPTER I

                       THE ORIGIN OF PYROTECHNY


Pyrotechny, or the Art of Firework-making, is of great antiquity, and
the date of its origin is quite unknown; indeed, it would be impossible
to define with any degree of exactitude what actually constitutes a
firework.

It is curious how universal is the belief that fireworks were dependent
upon the invention or discovery of gunpowder. Very little consideration
will prove the fallacy of this view; in fact, will show that the
reverse is probably the case. In India and China saltpetre (or nitrate
of potash) is found in large quantities, and was, no doubt, used by
the primitive inhabitants in far-off times for such purposes as curing
meat, cooking, etc. The dropping of a quantity in the camp fire may
have attracted the attention of some early inventor to the extent of
starting him on a series of what were probably the earliest chemical
experiments.

He would notice that the presence of saltpetre made the fire burn
brighter, and its use as a tinder maker would suggest itself by mixing
it with some substance which he knew to be combustible. The most common
fuel he knew of was wood, but it must be a powder to mix evenly with
saltpetre. Wood is not easily reduced to powder; saws had not been
invented, so that he could not add sawdust, and the nearest thing
he could get would be charcoal from the fire, which could easily be
reduced to powder. With this mixture he would be well on the way to
success in elementary pyrotechny.

The next step in his career as the first pyrotechnist is to utilise his
composition as an easy means of making fire. Gradually he gives up his
hitherto necessary tasks of hunting and trapping, as he receives the
fruits of other labours in return for his services as fire-maker to the
tribe.

The most important item in early social life is fire, the implements
for producing it the most valued property of the tribe; it was the
focus of religion and the centre of daily existence, so that any new
phenomenon connected with fire would be of the greatest interest to
primitive people, and any short cut to the production of fire would be
accorded more perseverance and care in its perfection than almost any
other invention.

Fire would be struck with a piece of iron pyrites on a flint, small
pieces of reguline particles of iron would be detached and fall on the
fire mixture unlit. Afterwards, when combustion of the mass of fire
mixture took place, these small pieces of metal would scintillate as do
the iron filings in a modern firework composition. This would give rise
to a further series of experiments, and gradually the composition known
as Chinese Fire would be evolved, which is known to have been in use in
the East from remote times.

Having arrived at a pyrotechnic composition, attempt to use it in
other ways besides fire-making would naturally follow, and sooner or
later the idea of filling the mixture into tubes would suggest itself,
especially as both in India and China (in one of which countries
pyrotechny undoubtedly originated) a serviceable tube—or to use the
modern term “case”—was ready to hand in any size or quantity in the
ubiquitous bamboo. The bamboo is in use for the purpose at the present
day in the East, and until recent times, when displaced by European
weapons, was used in the construction of ordnance of considerable size.
Mortars used for throwing firework shell up to six or more inches in
diameter are still in use in Japan and China, the barrel consisting of
a section of bamboo strengthened on the outside with a binding of
split cane.

[Illustration]

Having reached the point of charging composition into a tube, that is
to say confining it, a more or less violent explosion was likely or
rather certain to follow during the course of the experiments, which
might suggest the use of a tube as a means of discharging a projectile.
This would lead to research in the direction of the best composition
for the purpose and the evolution of gunpowder.

It must be remembered that the constituents of gunpowder must be
present in approximately exact proportion, whereas with primitive
pyrotechnic compositions, if the ingredients saltpetre and charcoal are
present, it is almost impossible to fail in getting some result.

The above suggestion must not be taken literally as a statement of
fact, but rather as an attempt on the part of the writer to trace the
stages by which pyrotechnic and explosive compositions came to be
evolved.

If one disabuses one’s mind of the curiously widespread belief that
all fireworks are composed chiefly of gunpowder, and that without the
invention of gunpowder fireworks could not have been constructed, it
seems far more likely that pyrotechny is based on the discovery of the
assistance given to combustion by saltpetre, than on the discovery of
gunpowder.




                              CHAPTER II

                        PYROTECHNY IN THE EAST


Pyrotechny undoubtedly had its genesis in the East, and for that reason
we will deal with its development there first. As he has intended
to convey, the writer is strongly of opinion that the discovery of
pyrotechnic compositions antedated that of gunpowder. In many cases
earlier writers have discovered passages which they consider prove the
use of firearms and gunpowder; in reality these refer to Greek-fire and
similar compositions, which were used as projectiles, being thrown from
machines or catapults, and not as propellants. Gunpowder as a mixture
of ingredients may have been known from remote times, as undoubtedly
were other simple pyrotechnic compositions, but all evidence goes to
show that its use as a propellant was not known until well into the
Christian Era.

The composition Greek-fire, known in ancient times as “naphtha,” was
a mixture of pitch, resin, and sulphur, with the addition in some
cases of crude saltpetre. It may be considered that in the absence of
the latter ingredient the mixture does not constitute a pyrotechnic
composition, but from the description of the use of “naphtha” in early
writings, it appears at least likely that it was generally present.

The fire was either enclosed in hollow stones or iron vessels, and
thrown from a catapult, or sometimes filled into the end of arrows and
assisted to propel them forward or sustain their flight.

Philostratus (170–250 A.D.), writing of the Indian Campaign of
Alexander the Great (B.C. 326), relates that the inhabitants of a
town on the river Hyphasis (Beas) “defended themselves by means
of lightning and thunder, which darted upon their besiegers.” This
has been considered as evidence of the use of firearms, but is more
probably the first reference to Greek-fire. Greek-fire or “naphtha” was
used at the defence of Constantinople between 660 and 667.

[Illustration]

At the siege of Pian-King Lo-Yang (1232), as mentioned in the Chinese
Annals, iron pots were thrown containing a burning substance which
could spread fire over half an acre, and described by the historians as
the “thunder which shakes heaven.”

The Mongolians attacking Bagdad in the year 1258 made use of similar
vessels, also fire arrows. Marco Polo, describing sieges of towns in
China 1268 to 1273, mentions the throwing of fire.

In most of the early records although noise is remarked upon, it is
apparently while the projectile is in the air or upon impact; this
disposes of the impression which many writers have formed that firearms
are referred to, there being no reference to an initial explosion.

Sir George Stanton, writing in 1798 of his embassy to the Emperor of
China, says that “nitre (saltpetre) is the daily produce of China and
India, and there accordingly the knowledge of gunpowder seems coeval
with that of the most distant historic events. Among the Chinese it has
been applied at all times to useful purposes ... and to amusement in
making a vast variety of fireworks—but its force had not been directed
through strong metallic tubes, as it was by Europeans soon after they
had discovered that composition.”

Although the place of origin of the art, pyrotechny has not developed
in the East as rapidly as in Europe, except in Japan.

Japanese pyrotechnists, with that wonderful capacity for careful
and exact manual work which is so characteristic of the race, have
developed aerial fireworks, that is to say, the shell, to a remarkable
degree of perfection. The compositions used are not to be compared with
European manufactures in point of colour or brilliance, but the effects
obtained are extraordinary. The stars, upon the bursting of the shell,
are thrown out in symmetrical patterns and designs, several examples of
which are given in the accompanying Japanese colour prints.

Daylight fireworks also originated in Japan. Instead of pyrotechnic
effects, the shell contains a grotesque balloon in the form of an
animal, human figure, or other form, which, being open and weighted
at the lower end, becomes inflated as it falls and remains in the air
for a considerable period. Other daylight effects are coloured clouds
formed by coloured powder, distributed by the bursting of the shell,
showers of streamers, confetti, and toys.

Chinese firework displays have often been enthusiastically described
by travellers in China. Whether it is that the glamour of the East
distorts the perceptions, or that these travellers have not seen a
European firework display, there is no doubt that such descriptions
are, to say the least, over coloured.

Chinese fire (a composition of saltpetre, iron filings, sulphur and
charcoal), a few simple colour compositions, and a large number of
Chinese crackers of varying sizes constitute a Chinese display; the
rest of the exhibition being eked out with lanterns, pictures, etc.,
which certainly do not come under the heading of pyrotechnics.

The writer once had an opportunity of witnessing a Chinese display of
some importance, lasting several hours, which produced the effect on
the mind of watching some performance or game of the rules of which one
was in entire ignorance. Pyrotechnically, only the crudest effects were
produced, the remainder of the display, consisting of such items as a
man slowly climbing a ladder carrying a lantern, was to the uninitiated
mystifying.

[Illustration]

The following is an account by a traveller in the early nineteenth
century of a Chinese display: “The fireworks, in some particulars,”
says he, “exceeded anything of the kind I had ever seen. In grandeur,
magnificence, and variety they were, I own, inferior to the Chinese
fireworks we had seen at Batavia, but infinitely superior in point of
novelty, neatness and ingenuity of contrivance. One piece of machinery
I greatly admired: a green chest, five feet square, was hoisted up by
a pulley fifty or sixty feet from the ground, the bottom of which was
so contrived as then suddenly to fall out, and make way for twenty
or thirty strings of lanterns, enclosed in a box, to descend from
it, unfolding themselves from one another by degrees, so as at last
to form a collection of full five hundred, each having a light of a
beautifully coloured flame burning brightly within it. This devolution
and development of lanterns was several times repeated, and at every
time exhibiting a difference of colour and figure. On each side was
a correspondence of smaller boxes, which opened in like manner as
the other, and let down an immense network of fire, with divisions
and compartments of various forms and dimensions, round and square,
hexagons, octagons, etc., which shone like the brightest burnished
copper, and flashed like prismatic lightnings, with every impulse of
the wind. The whole concluded with a volcano, or general explosion and
discharge of suns and stars, squibs, crackers, rockets and grenades,
which involved the gardens for an hour in a cloud of intolerable smoke.
The diversity of colour, with which the Chinese have the secret of
clothing their fire, seems one of the chief merits of their pyrotechny.”

It will be seen that lanterns play an important part in the exhibition,
and that when the fireworks proper are reached, the result is an
“intolerable smoke.”

Indian pyrotechnists are more advanced than their Chinese neighbours.
Firework displays carried out by them are nowadays more or less crude
attempts to reproduce European work.

The writer has seen a set piece evidently intended to follow a fire
picture seen in a European display carried out by small wicks burning
in oil instead of the “lances,” as the small fireworks used to outline
the pictures are called in this country.

In India as in China fireworks play a frequent part in religious and
civil ceremonies. In the former country, at certain festivals, a
primitive device for producing a series of reports is used. These are
called “adirvedis,” and consist of a series of short iron tubes fitted
to a wooden plank, charged with gunpowder and tamped with clay.

At weddings, crackers are largely used under a variety of names, such
as Vengagvedi, Gola, Pataka or Koroo. To-day these are simple crackers
filled with country-made gunpowder or the imported Chinese crackers.
Formerly almost the only composition used was chlorate of potash and
one of the sulphides of arsenic. A favourite form consisted of a small
quantity of the two ingredients put together unmixed into a piece of
rag with some small stones or grit and tied. The resulting fireworks
were similar to the “throw-down” crackers sold in this country.

Owing to the very large number of accidents caused by the casual
methods, both in manufacture and use, with this highly sensitive
composition, H.M. Chief Inspector of Explosives for India endeavoured,
in 1902, to secure its prohibition, as was done in this country in
1895, but it was not until 1910, when it had been established that
this composition was being used by anarchists, that it was finally
prohibited.

The most successful effect produced by Hindoo pyrotechnists is the
“Tubri.” The composition is here known as Chinese fire, a mixture of
charcoal, saltpetre, sulphur and iron dust, charged into either bamboo
tubes or earthen pots.

[Illustration]

It is a common practice to fix a pot at either end of a long bamboo,
which is whirled quickly about by a performer; the result produced is
quite good, but seems rather to come under the heading of juggling than
that of pyrotechnics proper. As the pots are theoretically the wrong
shape for such a purpose, that is to say, a large mass of composition
is burning through a narrow orifice, premature explosions are frequent.
This want of theoretical knowledge is noticeable throughout, but such
incidents seem to be appreciated as part of the show.

Another use of the earth pot is the “burusu,” a kind of red flare; the
composition used being sulphur, saltpetre, and nitrate of strontia.
Flare compositions are also used loose as in England, and are known as
“chandrajota” or “mahteb.”

Abusavanani or Hawai, that is to say, rockets, are now made similarly
to those manufactured in Europe except a bamboo case is most generally
used, but formerly chlorate of potash and orpiment seem to have been
employed for this purpose.

The firework shell under the name “out” is also manufactured very much
as in this country, except that the range of effects is very limited,
simple coloured stars being almost the only “garniture” used.

In Siam it is a custom, and one apparently of considerable antiquity,
to celebrate certain religious festivals with firework displays. These
displays take place in the day-time, and take the form of discharges of
rockets, some of which are of very large size; a writer giving their
length, exclusive of the stick, as from 8 ft. to 10 ft. The case is
composed of a section of bamboo bound with string. The composition
consists of coarse native powder, of which from 20 lbs. to 30 lbs. is
often used in one case. The rocket stick, which is of bamboo, varying
from 20 ft. to 40 ft. in length, is gaily decorated with coloured
paper and tinsel and fitted with bamboo whistles. A rough scaffold is
erected from which to fire the rockets, and according to those who have
witnessed such exhibitions, considerable altitudes are reached by the
rockets in flight. As may be expected with such crude methods, mishaps
are of frequent occurrence.

                              CHAPTER III

                         PYROTECHNY IN EUROPE


Pyrotechnic compositions and gunpowder are inextricably mixed together
in early European records; for our inquiries it will serve no useful
purpose to disentangle them, the latter being only a particular case
of the former. We will therefore deal with them together, taking the
evidence of the knowledge of one as that of both, as until gunpowder
is specifically mentioned as being used as a propellant in a gun or
similar weapon, there is nothing to distinguish it from any other
pyrotechnic composition.

The earliest record of European pyrotechny is in Claudius’ account of
the public festivities during the consulate of Theodosius in the fourth
century A.D., in which he describes fire “which ran about in different
directions over the planks without burning or even charring them, and
which formed by their twisting and turning globes of fire.”

Leo VI, Emperor of the East, in a work written about A.D. 900, says:
“We have divers ways of destroying the enemies’ ships, as by means of
fire prepared in tubes, from which they issue with a sound of thunder,
and with a fiery smoke that burns the vessels on which they are hurled.
A tube of tin must be put on the front of the ship to hurl this from.”

The most interesting reference of an early date is supposed to have
been written by Marcus Graecus in his “Liber ignium ad comburendos
hostes” (Book of fires for burning up the enemy), in which he not only
gives the exact proportions of the compositions, but describes what
is virtually the modern cracker, and also a primitive form of rocket.
The case of the former was only partially filled, as with the jumping
cracker of to-day, and although the wording is not very explicit, it
was apparently bent in a similar way.

The date of this work is a subject of controversy; some writers place
it as early as the eighth century, and it can only be said with
certainty that it is not later than 1280. The latter date is fixed by
the death of Albertus Magnus, who, in his book “De miribilibus mundi,”
from internal evidence, is obviously plagiarising the Liber Ignium.

Friar Roger Bacon (1214–94), in two of his works, refers at least twice
to compositions containing saltpetre, powdered charcoal, and sulphur.
In one place he refers to fires that “shall burn at what distance we
please”; in another to “thunder and corruscations,” which references
seem to suggest that he is describing something of a pyrotechnic nature
rather than the simple effect of gunpowder. His description in no way
indicates that he claimed to be the inventor, but rather as something
well known before.

Dr. Jebb, in his preface to Bacon’s “Opus Majus,” refers to what seems
to be an early example of both the rocket and the cracker.

Dutens, in his “Inquiries into the Origin of the discoveries attributed
to the Moderns” (1790), makes reference to many early writers, which
are mostly so vague and exaggerated that no definite conclusion can be
drawn from them; most refer to the early uses of Greek-fire or similar
composition.

Don Pedro, Bishop of Leon, says that “in 1343, in a sea combat between
the King of Tunis and the Moorish King of Seville ... those of Tunis
had certain iron tubes or barrels wherewith they threw thunderbolts of
fire.”

This description, if accurate, may be thought to suggest the use of
cannons, but it is more likely to refer to the use of Greek-fire;
this composition will, in certain proportions, if charged into a
strong tube, give intermittent bursts, projecting blazing masses of
the mixture to a considerable distance. The writer has seen this
effect produced in a steel mortar of 5½ inches diameter, the masses of
composition being thrown a distance of upwards of a hundred yards, a
considerable range in the days of close warfare. Anyone who has seen
this phenomenon will at once realise that here probably is the true
solution of many obscure early references to explain which so much
ingenuity has been expended.

An interesting fact which seems to have escaped the notice of writers
on this subject is that Theresa, daughter of Alfonso V. King of Leon
and the Asturias (A.D. 999), when married to Abdallah, King of Toledo,
took for device on her coat of arms a mortar in which a powder is being
pounded. This powder is supposed to represent gunpowder, a supposition
which is supported by the motto, “Minima maxima fecit” (A little makes
much). If gunpowder is intended, this must be one of the earliest
references to its quality of exploding, and it is difficult to explain
the meaning otherwise.

Richard Cœur de Lion used Greek-fire on his galley at the siege of Acre
in 1191, and it is thought by many that it was introduced into Western
Europe by the Crusaders, who had learned its use in the East.

Alfonso Duke of Ferrara had as his coat of arms a bomb-shell in flight,
and Antoine de Lalaing, Count of Hooghstraeten, had a bomb-shell
exploding in water. The adoption of these two devices at about the same
time (1540) seems to indicate that this projectile was coming into use,
that is to say, for military purposes at least.

An early reference to shell appears in Stowe’s Chronicles (1565). He
mentions two foreigners, Peter Brand and Peter Van Cullen, a gunsmith,
in the employ of Henry VIII (A.D. 1546), who “caused to be made
certain mortar pieces being at the mouth eleven inches unto nineteen
inches wide, for the use whereof to be made certain hollow shot of
cast-iron, to be stuffed with firework or wild-fire, whereof the bigger
sort for the same had screws of iron to receive a match to carry fire
kindled, that the firework might be set on fire for to break in pieces
the same hollow shot, whereof the smallest piece hitting any man would
kill or spoil him.” The missile is to all intents the firework shell of
the present day, except that the modern shell has a papier-maché case.

The reference to “firework” without further explanation seems to
indicate that by this time the word was well established in use.
Shakespeare makes three references to fireworks. In “Love’s Labour’s
Lost,” Act V, Scene 1, Don Armado says: “The King would have me present
the Princess with some delightful entertainment, or show, or pageant,
or antic, or firework.” In “Henry VIII,” Act I, Scene 3, we read of
“fights and fireworks”; and again in “King John,” Act II, Scene 1:
“What cracker is this same that deafs our ears?”

However, nothing in the nature of a firework display appears to have
taken place, at least in this country, before the time of Elizabeth.

The use of fire for theatrical purposes, as in Mystery Plays to
represent the “gate of Hell,” has been taken by some to refer to
fireworks, but this seems doubtful as flames are mentioned, and it is
more probable that a torch or similar contrivance was used.

When, however, we read a description of a barge at the coronation of
Anne Boleyn, in 1538, carrying a dragon “casting forth wild fire—and
men casting fire,” the reference to some pyrotechnic effect, however
primitive, seems fairly obvious.

The men performers may be considered as early types of the “green
man” who made his appearance somewhat later. The office of this
performer was to head processions carrying “fire clubs” and scattering
“fireworks” (probably sparks) to clear the way.

One account of a procession to the Chester Races on St. George’s Day,
1610, commences as follows: “Two men in green ivy, set with work upon
their other habit, with black hair and black beards, very ugly to
behold, and garlands upon their heads, with great clubs in their hands,
with fireworks to scatter abroad to maintain the way for the rest of
the show.”

The fire clubs referred to are described in John Bate’s book, published
in 1635; the same writer illustrates a “green man” on the title page of
his work.

[Illustration: Facsimile Title-page of Bate’s Book, showing a
  “Green Man.”]

Regarding the origin of the Green Man, it has been suggested that the
character was evolved from the wild men, satyrs, monsters, etc., which
appeared in the earlier exhibitions. This may or may not be so, but
another explanation suggested to the writer by an old Danish print of
the sixteenth century is at least plausible.

This print, which apparently represents a floating firework device of
the old scenic type, shows two figures carrying fire clubs wearing
leaves, and suggesting immediately the green man of a slightly later
date.

Behind them are two figures holding rockets, leaving no doubt that a
firework display is portrayed.

On the other hand, apart from the fact that normally they have no fire
issuing from their clubs, the supporters of the Danish royal arms might
be here depicted; a supposition which is borne out by the fact that
the figure surmounting the erection carries the crown and sceptre of
Denmark.

It seems quite within the bounds of possibility that these two figures
were introduced into Danish displays as a compliment to Royalty,
and that later they appeared in England, and became, as it were,
acclimatised. Colour is lent to this belief by the record of a display
given on a float by the King of Denmark in 1606 upon his departure from
this country, where he had been on a visit to his brother-in-law, James
I.

This exhibition seems to have given James a taste for fireworks, and
one at least of the Danish artists appears to have remained in this
country, as some months after James had a display carried out by “a
Dane, two Dutchmen, and Sir Thomas Challoner.”

In 1572 a firework display was given in the Temple Fields, Warwick, by
the Earl of Warwick, then Master-General of the Ordnance. The occasion
was a visit to the castle by Queen Elizabeth, who appears to have been
rather partial to such exhibitions.

The display consisted of a mimic battle, with two canvas forts for a
setting; noise was provided by the discharge of ordnance of various
sizes; the fireworks proper seem to have taken the form of flights of
rockets. The display was evidently conducted in a somewhat reckless
manner, some houses being set on fire, and some completely destroyed,
the two inhabitants of which are said in a contemporary report to have
been in bed and asleep, although how that could be with continuous
discharge from twenty pieces of ordnance, to say nothing of “qualivers
and harquebuses,” in the immediate neighbourhood, is to say the least
curious.

Two other displays attended by Elizabeth were those at Kenilworth in
1572 and at Elvetham in 1591.

[Illustration: A Display of the Earliest Type. From a contemporary
  print (_c._ 1650).]

The first European people to make headway in the art of pyrotechny
proper appear to have been the Italians. Vanochio, an Italian, in
a work on artillery, dated 1572, attributes to the Florentines and
Viennese the honour of being the first who made fireworks on erections
of wood, decorated with statues and pictures raised to a great
height, some in Florence being forty ells, or seventy-two feet high.
He adds that these were illuminated so that they might be seen from a
distance, and that the statues threw out fire from the mouths and eyes.

He refers to the practice, which survived up to the end of the
eighteenth century, of constructing elaborate temples or palaces richly
decorated, with transparencies illuminated from inside, statuary,
gilding, floral and other decorations. On these erections the fireworks
proper were displayed, and which were then called artificial fireworks.
Nothing very large in the way of firework set-pieces seems to have been
attempted, but effect was gained by repetition of a small device over
the facade of the building.

Displays were given annually in Florence at the Feast of St. John and
the Assumption. This custom extended to Rome, where the festivals were
given on the Feast of St. Peter and St. Paul, and at the rejoicings on
the election of a Pope.

The towers and fortifications of the castle of St. Angelo furnished
suitable spots for these, being visible from the greater part of the
city of Rome, and what are described as braziers, firepots, and other
fires would be placed there, so as to give a great display without the
expense of a building.

Evelyn, the famous diarist, gives an account of one such display which
he witnessed in 1664.

In other towns that wished to imitate the festival of Rome, it was
arranged to place illuminations on the highest towers and steeples of
the towns, but as it was found that there was considerable danger of
fire from these, it was afterwards preferred to make suitable erections
in the great public squares, which were convenient for the exhibition
itself and also for the sightseers.

The Italians appear to have held the supremacy until the end of the
seventeenth century.

In the book of Artillery by Diego Ufano, written in 1610, we read that
only very simple fireworks were made in his time in Spain and Flanders,
consisting of wooden framework supporting pots of fire wrapped round
with cloth dipped in pitch, but that more than fifty years before
magnificent spectacles could be seen in Italy.

In 1615, on the occasion of the marriage of Louis XIII, a display was
given at Paris in the Place Royale, in which were included combats
between men carrying illuminated arms.

In 1606 the Duc de Sully gave a spectacle which depicted a battle
between savages and monsters, the former throwing darts and fire. A
similar display had previously been given on the occasion of the entry
of Henry II into Rheims, and it was repeated in 1612.

These spectacles, which are quoted as firework displays, cannot rightly
be considered as such, fireworks playing a comparatively secondary part
in the exhibitions.

A display of this nature to celebrate the capture of Rochelle was
conducted by Clariner of Nuremberg, a celebrated pyrotechnist of the
day.

During the reign of Louis XIV, 1638–1715, great advances were made in
pyrotechny in France; great displays were given on the return of the
King and Queen to Paris in 1660, on five consecutive days at Versailles
in 1676, also on the occasion of the birth of the Dauphin in 1682, in
Paris at the Louvre, Dijon, and Lyons.

A particularly fine display in celebration of the Peace of Riswick,
1669 (for which event displays took place in several countries), is
mentioned by Frézier, who wrote a treatise on pyrotechny (1747); it
was, he says, witnessing this display that inspired him to study the
art.

[Illustration: Set Piece of the Scenic Type.]

One of the chief causes of progress in France was the encouragement
given by Louis XV (1710–1774) to the pyrotechnists Morel Torré and the
Ruggieri brothers, the latter being Italians from Bologna who became
naturalised Frenchmen, and contributed very greatly to the development
of French pyrotechny. They were the first to rely chiefly on fireworks
for the effect, instead of using them merely to embellish a scenic or
architectural structure.

Louis XV expended large sums of money on displays, one of the finest
being that fired at Versailles in 1739 by Ruggieri, on the occasion
of the marriage of Madame La Première of France with Don Philippe of
Spain. Writing of this display in 1821, Ruggieri’s son says: “There
appeared for the first time the Salamander la Rosace and le Guilloche,
which are still admired to-day.” These are purely pyrotechnic pieces
and devices; similar or identical ones are used at the present day,
which seems to indicate that fireworks proper were making headway
against scenic effect.

Other displays in France during the eighteenth century were those on
the occasions of the birth of the Duke of Brittany, 1704; birth of the
Dauphin, 1730; the convalescence of the King, 1744; and the return of
the King to Paris, 1745. Also there is in existence a series of prints
which, but for the fact that they are described as fireworks, would be
taken to be scenic tableaux; whether the figures are human beings or
wax-works is not indicated. These were erected in celebration of the
following events:—The taking of Tournay, the taking of Chateau Grand,
Victory over the Allies, all dated 1745; the taking of Ypres, 1747,
all of which took place in Paris before the Hotel de Ville. Similar
displays were given in Lyons in 1765 to celebrate the taking of Fort
San Philippe, and at Soleure in 1777, in honour of the Swiss Guard.

Displays took place at Versailles (1751) on the occasion of the birth
of the Duke of Burgundy. In 1758–9 came a further series of victory
celebrations in honour of the victory of Lutzelberg, over the English
in America, and over the Allies at Bergheri, all of which appear to
have been of the “tableau” type mentioned above.

There were also displays for the peace celebrations on the Seine, 1763,
the birth of the Dauphin, 1782, in the Place de Geneve, and peace
rejoicings, 1783, before the Hotel de Ville.

Ruggieri, however, states in his book that the display fired on the
marriage of Louis XVI (or, as he then was, the Dauphin) was the only
display since the great fetes of 1739 which showed any considerable
advance in the art; he may, however, be in some degree biased as his
father was concerned in each of these displays.

                              CHAPTER IV

                  PYROTECHNY IN EUROPE (_continued_)


During the later part of the seventeenth century, and subsequently,
many prints appeared depicting firework displays; their number seems
quite out of proportion to the total number of prints published in that
period.

Possibly this may be taken as some indication of the popularity of
firework displays at the time, or may give the measure of the favour in
which they were held by the artists of the day.

Many of these prints are of little value to the student of pyrotechny,
as they merely depict the more or less elaborate structure for
the display by daylight, and whatever may be their architectural
or artistic merit there is generally no indication of what actual
fireworks were to be used, or how they were to be displayed.

In some cases a list of the works is given under the engraving,
adding greatly to its value in the eyes of the pyrotechnist, and
some, although they are considerably in the minority, are intended to
represent the display in progress, although on the rather futuristic
method of showing everything going off at one time.

A series of prints published in Germany during the seventeenth century
are among the earliest in which a serious attempt is made to depict
pyrotechnic effects; the series includes “Swedish Fireworks,” dated
1650; “Fireworks at Nuremburg in celebration of Peace,” of the same
date; “Fireworks given at Pleissenburg by the Prince of Saxony,” 1666;
and the same year, “Fireworks at Vienna”; all three prints show a
good display of rockets, also bonfires, and there are indications
of primitive wheels. The same remarks apply to a very fine plate
published in 1669, depicting a display given at Stockholm in honour of
the investiture of Charles XI of Sweden with the Order of the Garter
by the British Ambassador. This engraving carries with it a feeling
of conviction that it is an actual representation of the scene, and
not—as is the case with earlier and with some later work—that the
artist is drawing on his imagination. In many of the earlier prints it
is difficult to judge if the artist is depicting what he imagined, or
monsters and scenic effects actually constructed for the display.

It is worthy of note that even in early times, speaking
pyrotechnically, the value of water in enhancing the effect of
fireworks seems to have been realised. The display at Stockholm we
have already mentioned appears to have taken place on the sea front.
Many of the larger French displays of the seventeenth and eighteenth
centuries were fired with a foreground of water; in those at Versailles
full advantage was taken of the wonderful fountains and ornamental
water, the display given in celebration of the entry of Louis XIV in
Paris after his marriage being given on the Seine, and many of the
early English displays took place on the Thames. Probably the earliest
contemporary account of any length of a firework display in England is
one headed “The Manner of Fire-Workes shewed up upon the Thames” in
celebration of the marriage of Prince Frederick (Elector Palatine) with
the daughter of James I in 1613. We read “many artificiall concusions
in Fire-Workes were upon the Thames performed.

“First, for a welcome to the beholders a peale of Ordnance like unto
a terrible thunder ratled in the ayre.... Secondly, followed a number
more of the same fashion, spredding so strangely with sparkling
blazes, that the skie seemed to be filled with fire.... After this,
in a most curious manner, an artificiall fire-worke with great wonder
was seen flying in the ayre, like unto a fiery Dragon, against which
another fierrie vision appeared flaming like to Saint George on
Horsebacke, brought in by a burning Inchanter, between which was then
fought a most strange battell continuing a quarter of an howre or more;
the dragon being vanquished, seemed to roar like thunder, and withall
burst in pieces, and so vanished; but the champion, with his flaming
horse, for a little time made a shew of a tryumphant conquest, and so
ceased.

[Illustration: Great Firework Display near Stockholm, July, 1669.
  To celebrate the Investiture of Charles XI, King of Sweden, with
  the Order of the Garter by King Charles II.]

“After this was heard another ratling sound of Cannons, almost covering
the ayre with fire and smoke, and forthwith appeared, out of a hill of
earth made upon the water, a very strange fire, flaming upright like
unto a blazing starre. After which flew forth a number of rockets so
high in the ayre, that we could not chose but approve by all reasons
that Arte hath exceeded Nature, so artificially were they performed.
And still as the Chambers and Culverines plaide upon the earth, the
fire-workes danced in the ayre, to the great delight of his Highnes and
the Princes.

“Out of the same mount or hill of earth flew another strange piece of
artificiall fire-worke, which was in the likenes of a hunted Harte,
running upon the water so swiftly, as it had been chaced by many
huntsmen.

“After the same, issued out of the mount a number of hunting-hounds
made of fire burning, pursuing the aforesaid Harte up and downe the
waters, making many rebounds and turnes with much strangenes; skipping
in the ayre as it had been a usual hunting upon land.

“These were the noble delights of Princes, and prompt were the wits of
men to contrive such princely pleasures. Where Kings commands be, Art
is stretcht to the true depth; as the performance of these Engineers
have been approved.

“But now again to our wished sports: when this fiery hunting was
extinguished, and that the Elements were a little cleared from fire and
smoke, there came sailing up, as it were upon the Seas, certaine ships
and gallies bravely rigged with top and top gallant, with their flagges
and streamers waving like Men of Warr, which represented a Christian
name opposed against the Turkes; where, after they had awhile hovered,
preparing as it were, to make an incursion into the Turkish country,
they were discovered by her Towers or Castles of defence, strongly
furnished to intercept all such invading purposes, so sending forth the
reports of a cannon, they were bravely answered with the like from the
gallies, banding fire and powder one from another, as if the God of
Battle had been there present.

“Here was the manner of a sea-fight rightly performed: First, by
assailing one another, all striving for victorie, and pursuing each
other with fire and sword: the Culverines merrily plaid betwixt them,
and made the ayre resound with thundering echoes; and at last to
represent the joyes of a victorie, the Castles were sacked, burned, and
ruinated, and the defenders of the same forced to escape with great
danger.”

The foregoing appears to be the only full account of a display in
England during the early part of the seventeenth century, but in the
first serious work on fireworks, “Pyrotechnia,” by John Babington,
“gunner and student of the mathematicks,” we find a proposed programme
for “a generall piece of fire-worke for land, for the pleasure of a
Prince or some great person.” The spectacle consists of two castles
with mechanical effects, but includes such devices as horizontal and
vertical wheels, flights of rockets, line rockets and “torches of
beautifull fire.” Babington also describes the St. George and Dragon
device, which is merely scenic, the figures being of wickerwork and
canvas with slight firework effects. At this time, according to a
“History of Colleges in and arround London,” there were “many men very
skilful in the art of pyrotechny and fireworks.”

In a book on fireworks, published in the same year, by John Bate,
the author concludes by saying: “I might have been infinite in the
describing of such like with Ships, Towers, Castles, Pyramides. But,
considering that it would but increase the price of the book and not
better your understanding, since all consist of the former workes,
which are so plainly described as that the most ignorant may easily
conceive thereof, and (if any whit ingenious) thence contrive others,
of what fashion they list.” From this it would appear that firework
displays were by that date a well-established institution.

Pepys, in his account of the coronation of Charles II, 1661, says:
“We staid upon the leads and below till it was late, expecting to see
the fireworks, but they were not performed to-night.” He seems to
have looked upon fireworks as a matter of course on such an occasion.
However, a display of considerable size did take place, conducted by
Sir Martin Beckman, later Firemaster to James II, who was responsible
for most of the important displays until 1706. One of the earliest
prints of an English firework display is that depicting the fireworks
on the Thames at Whitehall for the coronation of James II, 1685, in
which the artist appears to have drawn somewhat on his imagination.

Three years later an elaborate display was given on the Thames to
celebrate the birth of an heir to the throne, who was afterwards known
as the Old Pretender. In the same year we again see fireworks on the
Thames, this time to celebrate the reception of the Prince of Orange.

[Illustration: Fireworks on the Thames, June 17th, 1688. To
  celebrate the birth of a son to King James II. known to fame first
  as the Prince of Wales, and afterwards as the Old Pretender.]

In 1690 displays were given, again on the Thames, and in Covent Garden,
on the occasion of the King’s return from Ireland.

The taking of Namur, 1695, was celebrated by a display in St. James’s
Square, and on the same site two years later, the celebrations for
the Peace of Riswick. This latter is depicted in a fine engraving,
giving the following list of fireworks used on the occasion:—“1,000 Sky
Rockets, from four to six pounds weight; 200 Shell; 2,400 Pumps with
Starrs (Roman Candles); 1,000 Cones; 7,000 Reports; 15,000 Swarms; 400
Light Balls; 23 Rocket Chests, each containing 60 rockets from one to
four pounders.”

John Evelyn, in his “Diary,” says: “The evening concluded with
illuminations and fireworks of great expense.” The display cost £12,000.

There seem to have been no fireworks in London at the coronation of
either Anne or the first two Georges, although on the former occasion
rockets appear to have been fired from the Fleet at Spithead.

The Peace Rejoicings of 1713 were the occasion of another display
on the Thames off Whitehall, the erection being about 400 feet long
on barges chained together in the stream. A feature of this display
was the water fireworks, described as: “1,500 small and large water
Rockets; 5 large water Pyramids; 4 water fountains; 13 Pumps; 21
standing Rockets, with lights all swimming on the water; 84 of Coll
Borgards; large and small Bees swarms, half of which were set with
lights to swim on the water.”

The next event to be celebrated by firework displays on a large scale
was the Peace of Aix-la-Chapelle; these were given at Paris, The Hague,
London, and St. Stephen’s Green, Dublin. The Duke of Richmond was
responsible for a display on the Thames off Whitehall, the official
display taking place in Green Park, and was on a scale unequalled in
this country until well into the last century. It was conducted by the
famous pyrotechnist Gaetano Ruggieri, who came over from France for the
purpose, assisted by Gioseppe Sarti, under the direction of the Board
of Ordnance.

Following the practice of the period, an elaborate structure was
prepared. The following is taken from the official programme:

         “A DESCRIPTION OF THE MACHINE FOR THE FIREWORKS, &c.

  “The Machine is 114 feet high to the Top of His Majesty’s arms, and
  is 410 feet long. It was invented and designed by the Chevalier
  Servandoni and all the framing was performed by Mr. James Morris,
  Master Carpenter to the Office of Ordnance.

  “The Ornaments of this Machine are all in Relief, and it is adorned
  with Frets, Gilding, Lustres, Artificial Flowers, Inscriptions,
  Statues, Allegorical Pictures, etc.”

According to a contemporary newspaper report, the construction occupied
from November 7th until April 26th. It was composed of timber covered
with canvas, whitewashed and sized.

The display commenced about six o’clock, and continued until after
twelve; during the display the left wing caught fire, which prevented
the firing of some of the devices. Indeed, according to Walpole, the
Duke of Richmond’s display on the Thames a few weeks later consisted
largely of fireworks which had not been fired owing to this occurrence,
and which the noble duke had bought up cheap.

Among the items were included the following:—Regulated Pieces, Fixed
Suns, Stars of six Points, and between each point a Ray, a large
vertical Sun moved by double Fires, Cascades, Pyramids (40 feet high)
of Gerbs, etc., etc. The chief piece seems to be one “from whence Fire
issues out and retires within, twelve times alternately; when without,
it forms a Glory; when within, it composes a Star of eight Points, and
then changes to a Royal brilliant Wheel, whose Fire is thirty feet in
diameter, and is moved by twelve fires.”

The remainder of this century in England appears to be rather barren of
firework displays on a large scale.

A writer in the “St. James’s Chronicle,” under the date February 18th,
1764, in a letter advocating certain improvements in St. James’s Park,
evidently recalling the outcry over the 1749 display, observes: “We
had no fireworks at the peace last year, that will surely obviate any
argument preferred against the expense of the undertaking.”

Until nearly the end of the eighteenth century, according to Strutt,
writing at that time, it was customary “for the Train of Artillery to
display a grand fire-work on Tower Hill, on the King’s Birthday, but
owing to the disturbances that occurred, the inhabitants a few years
since petitioned against it.” There was, however, a great increase in
the number of displays. Fireworks became a feature of the programme of
the majority of the then fashionable tea and pleasure gardens.

Walpole describes a firework display given in 1763 by the notorious
Duchess of Kingston, who was thirteen years later tried by her peers on
a charge of bigamy.

The display appears to have taken place in Hyde Park, opposite the
residence of the Duchess, then at the height of her popularity. He
records that “the fireworks were fine and succeeded well.” One item
seems curious to modern ideas; it took the form of a cenotaph for the
Princess Elizabeth, a sister of the king, bearing the inscription: “All
honours the dead can receive.”

The sequel was even more extraordinary, as “about one in the morning
this Sarcophagus burst into crackers and guns.”

[Illustration: Firework Display given by the Duke of Richmond on
  the Thames off Whitehall, May 15th, 1749, to celebrate the Peace of
  Aix-la-Chapelle.]

Lieutenant Jones, who published a book on fireworks in 1765, in his
preface makes the following remarks:

“I own I cannot help reflecting with some kind of chagrin that whenever
we have had occasion for these sort of diversions to be exhibited in
England we have almost always had recourse to foreigners to execute
them; if this has been owing to the ignorance of our own people on this
subject I shall be very happy if it is in my power to correct it; if it
is only owing to that prevailing fondness we entertain for everything
foreign I know no remedy for that evil but time and experience.”

To a certain extent his complaint seems justified; as we have seen,
the Aix-la-Chapelle celebrations were conducted by foreigners—Ruggieri
and Sarti. Later in the century, Morel Torré, who, as previously
mentioned, collaborated with Ruggieri in pyrotechnic displays for Louis
XV, and several other pyrotechnists came to this country and conducted
displays. At the same time, however, there were undoubtedly many
capable pyrotechnists of English nationality, who found scope for their
abilities in the exhibitions given in the pleasure gardens of London
and the provinces in the eighteenth and early nineteenth centuries.

A history of pyrotechny would not be complete without a survey of these
popular places of amusement, and we propose in the following chapter to
give a brief summary of the better known places of resort.




                               CHAPTER V

                      THE LONDON PLEASURE GARDENS


During the eighteenth and first half of the nineteenth centuries the
Pleasure Gardens filled a position in the lives of a large proportion
of the public comparable with that of the Cinema to-day.

To the great mass of the public, the most general form of evening
relaxation was a visit to one or other of these places of resort.
Apart from meals of a more or less elaborate nature, and liquid
refreshments of various kinds, a great variety of entertainments were
provided, varying from displays of horsemanship to exhibitions of
paintings. Of these diversions none were more general than fireworks
and illuminations. At many gardens fireworks formed a regular feature
of the programme, at others, generally less ambitious undertakings,
displays were confined to occasions, such as the King’s Birthday.

Space will hardly permit of more than a glance at those resorts
situated in the provinces, but a description of those in the London
area may be taken as typical.

Captain Marryat, in “Peter Simple,” gives an account of a visit to
Postdown Fair, near Portsmouth, and an adjournment to the local
Ranelagh Gardens to “see the fireworks.” As the pyrotechnist was
behind time, Peter Simple and his friends took it upon themselves to
fire the display. “In about half a minute off they all went in the
most beautiful confusion; there were silver stars and golden stars,
blue lights and Catherine Wheels, Mines and Bombs, Grecian fires and
Roman Candles, Chinese Trees, rockets and illuminated mottoes, all
firing away, cracking, popping, and fizzing at the same time. It was
unanimously agreed that it was a great improvement on the intended
show.”

Undoubtedly the gardens best remembered at the present day are Vauxhall
and Ranelagh, neither of which were early in the field in presenting
firework displays to the public.

The first displays took place at Vauxhall about 1798, more than half a
century after their appearance at some of the less famous gardens, and
did not become a permanent feature of the programme until 1813. They
continued regularly until the final closing of the gardens in 1859, the
final item of the programme being “Farewell for Ever” in letters of
fire. In 1813 an item in the firework programme was the performance of
Madame Saqui, which was to slide down an inclined rope 350 feet long
from the top of a mast 60 feet high, erected on the firework platform,
enveloped in fireworks. So popular did this exhibition become that it
was repeated here by other performers, by Longueman in 1822, and later
by Blackmore.

The best-known pyrotechnists connected with Vauxhall were Southby,
Mortram, and Hengler, the first display being by an Italian named
Invetto.

Pyrotechnic displays at Ranelagh became a prominent feature of the
amusements about 1767. The pyrotechnists Angelo, father and son, during
that and the following years, helped to establish these displays in
popularity, followed by Clithero, Caillot, Brock, Rossi, and Tessier,
up to the closing of the gardens in 1805, after which date they appear
to have been opened from time to time on special occasions. “The
Morning Chronicle” of June 1st, 1812, announces that “By the Authority
of the Right Hon. the Lord Chamberlain” these gardens would be open “in
Honour of His Majesty’s Birthday, with a grand naval and military Fete,
and a superb exhibition of Fireworks.”

An interesting old advertisement, dated 1766: “For the Benefit of the
General Lying-in Hospital. The most superb and Magnificent Fireworks
ever exhibited at that Place, under the conduct and direction of Mr.
Angelo.” It would appear from this that fireworks had been fired at
Ranelagh earlier than 1766, but they could not have been a regular
feature before 1767.

Cupers Gardens, which stood on the south side of the river,
approximately on the site of the Waterloo Bridge approach, were for
a long period the scene of popular firework displays. Commencing
about 1741, these displays were as elaborate as any of this period.
The earlier displays appear to have been conducted by “the ingenious
Mr. Worman,” who seems to have relied to a considerable extent on
transparencies and scenery; in 1749 and 1750 he reproduced in miniature
the firework “machine” or Temple used in the respective official
displays in Green Park, and at The Hague for the Aix-la-Chapelle peace
celebrations. Other scenic effects were a view of the city of Rhodes
with a model of the Colossus; Neptune, issuing from a grotto below
drawn by sea-horses, set fire to a pyramid or an “Archimedan worm” and
returned.

Clithero was also associated with these displays, producing similar
scenic effects, including a naval engagement in 1755, which was the
last year of fireworks in these gardens.

The earlier displays at Marylebone Gardens took place about the middle
of the eighteenth century. In 1751 a display is announced to take place
at eleven o’clock, and “a large collection” of fireworks was advertised
in 1753. Some at least of these earlier displays were fired by Brock,
whose son, later on, worked here in conjunction with Torré. In 1769 the
displays were under the direction of Rossi and Clanfield. From 1772 to
1774 was the most successful period of the fireworks at these gardens;
they were then under the direction of Torré. A popular item, afterwards
copied by Marinari at Ranelagh, was the “Forge of Vulcan,” a scenic
display concluding with the eruption of Mount Etna.

On the occasion of Torré’s benefit, in 1772, there was a further
exhibition of this kind, representing Hercules delivering Theseus from
Hell.

During this period attempts were made by neighbouring residents to stop
the displays as a nuisance, but nothing came of it, and the fireworks
continued.

At the annual festival in 1772, the display included a temple of
“upwards of 10,000 cases of different fires, all lighted at the same
time.”

Other pyrotechnists firing at the gardens were Clithero and Caillot,
both of whom had conducted displays at Ranelagh, the latter being
responsible for the fireworks up to the closing of the gardens about
1778.

It is recorded that Dr. Johnson once visited the gardens on a firework
night, but unfortunately a wet one, and notice was given to the
handful of visitors that the fireworks were wet and the display would
be cancelled. The doctor, however, was of opinion that it was a “mere
excuse to save their crackers for a more profitable company,” and
suggested that a threat to break the lamps would result in the show
being forthcoming. Some young men standing by endeavoured, under his
direction, to ignite the pieces, but unsuccessfully.

The Mulberry Gardens, Clerkenwell, were among the earliest to make
fireworks a feature. Displays took place from the opening in 1742, and
ten years later Clanfield gave a display each evening.

Two neighbouring taverns, “Lord Cobham’s Head” and the “Sir John
Oldcastle,” had displays from 1744, and in 1751 “New fireworks in the
Chinese manner” were announced at the latter establishment.

The New Wells, in the same neighbourhood as the foregoing, had had
a display as early as 1740, but it appears to have been of a scenic
nature, representing the Siege of Portobello.

The “Star and Garter,” Chelsea, advertised displays by Signor Genovini
of Rome, in 1762, and “Jenny’s Whim,” in the same neighbourhood, had
displays somewhat earlier, the place having been established as a
pleasure resort by a pyrotechnist.

Cromwell Gardens, in the vicinity of the present Cromwell Road, had
what appears to have been a small display in 1784.

Rossi and Tessier, the pyrotechnists of Ranelagh, gave displays at
the Bermondsey Spa Gardens in 1792. A representation of the Siege of
Gibraltar was given, and on September 28th of that year, “by special
desire the Battle of the Fiery Dragons, and the line comet to come from
the Rock of Gibraltar and cause the Dragons to engage.” Brock also gave
displays here later.

Finch’s Grotto Gardens, whose site is now occupied by the headquarters
of the Metropolitan Fire Brigade in Southwark, had occasional displays
of fireworks about 1770, as did the Temple of Flora in the Westminster
Bridge Road, about the same date. Clithero advertised a display of
fireworks at Jamaica House, Rotherhithe, in 1762.

A Peace Celebration display is announced for February 7th, 1749, to “be
play’d off this evening in the Field adjoining to the Tavern called
Bob’s Hall.”

In 1788 Astley senior advertises, to take place at the Royal Grove
and Astley’s Amphitheatre, Westminster Bridge, a “Double Display of
Fire-Works.... Numerous Devices prepared in the usual way from Powder,
etc., which will be alternatively played off with the new-invented
Philosophical Fire-Works, under the direction of Mons. Henry, the
inventor and Professor of Natural Philosophy from Paris.”

The same year he announces a display “on the Thames immediately after
Astley’s Exhibition in Honour of His Majesty’s Birth-day,” and
concludes by saying “the Fireworks are made under the Direction of Mr.
Astley, by Messrs. Cobonell & Son, who will let them off on the Thames
this evening at different signals from Mr. Astley, Sen., who will be
mounted on the Gibraltar Charger, placed in a Barge, in the Front of
the line of Fireworks.”

[Illustration: Firework Temple at Vauxhall, 1845. From a woodcut in
  “The Illustrated London News.”]

The “Philosophical fireworks” above mentioned were evidently an
imitation of those exhibited at the Lyceum by Diller, which he
describes as “Philosophical Fireworks from Inflammable Air without
smell, smoke or Detonation.” These appear to have been nothing more
than gas jets arranged in patterns and designs, some revolving and some
stationary. Air was forced from a bladder through a sponge saturated
with ether. Movement and variation were produced by turning on and off
the gas from separate sets of holes. Two colours only appear to have
been produced—rose and green; these were by the addition of strontia
and baryta or copper.

A handbill is in existence advertising a similar display at Hull in
1804, by W. Clarke.

During the early part of the nineteenth century several gardens round
London made a feature of pyrotechnic displays. The Mermaid Gardens,
Hackney, in “The Morning Chronicle” of June 1st, 1812, announces “the
greatest feast for the eye ever exhibited is a superb firework by that
unparalleled artist, Mr. Brock, Engineer.”

The Yorkshire Stingo and Bayswater Tea Gardens in the west gave
displays up to the early forties. White Conduit House, in the Islington
district, had firework displays from 1824 up to shortly before the
closing of these gardens in 1849.

Rosherville Gardens, opened in 1837, the North Woolwich Gardens, the
Eagle, 1825–82, the Globe, Mile End, the Cremorne, 1843–77, all had
their firework displays. The best known, however, for this feature
were the Surrey Zoological Gardens, 1831–56, where Southby, of
Vauxhall, conducted displays for several years, producing pyrotechnic
and scenic displays there. In 1841 he gave a reproduction of the
fireworks of St. Angelo, and the Illumination of St. Peter’s, Rome,
which proved a great attraction to the gardens.

In the provinces the Belvue Gardens, Manchester, and the Clifton
Zoological Gardens, Bristol, have made a feature of firework displays
in their list of attractions, those at the latter being carried out in
1835 by Gyngell.

The famous Cremorne Gardens made a feature of pyrotechnic displays and
spectacles of the scenic type with more or less regularity from their
opening in 1846 down to the final closing owing to public petition in
1877. The earlier displays were carried out by Mortram and Duffel.

Firework displays of a somewhat more ambitious nature have been given
from time to time at the Alexandra Palace, no doubt in emulation of the
historic Crystal Palace displays, which are dealt with in the ensuing
chapter.




                              CHAPTER VI

           FIREWORKS IN THE NINETEENTH & TWENTIETH CENTURIES


As we have seen, the commencement of the eighteenth century was marked
by great activity in the pyrotechnic art.

Firework displays were looked upon as a necessary item in the programme
of a place of public entertainment. So ambitious did these displays
become, owing to keen rivalry existing between the various resorts,
that any official display in celebration of peace or like event must of
necessity be on a scale of unexampled lavishness.

No official display of note appears to have been given in London during
the first thirteen years of the nineteenth century, or indeed since
the Aix-la-Chapelle peace display. The reason may have been the public
outcry on the score of waste on that occasion.

They were totally prohibited at the coronation of George III, and at
his jubilee in 1809 there were apparently no firework displays in
London, although more than forty towns about the country celebrated the
event pyrotechnically, and a fine display was given from the Fleet at
the Nore.

The largest public firework exhibition on this occasion was that given
at Bombay, where the celebration took place earlier in the year, the
date selected being June 4th, the King’s birthday, instead of October
25th, the actual anniversary of his accession.

The Peace of 1802, although no official display was given, was the
occasion of much private pyrotechnic enterprise, the fireworks and
illuminations in London lasting nearly a week.

The Peace of 1814 was signalised in London by several displays: the 1st
of August was chosen for the Peace Celebration, it being the centenary
of the accession of the House of Brunswick, and also the anniversary of
the Battle of the Nile.

The display in Hyde Park commenced with a naval engagement on the
Serpentine between model warships representing the English and the
combined French and American Fleets. This item, which lasted three
hours, was followed by a display of water fireworks. The display in
Green Park commenced at ten o’clock, one of the chief items being
the “grand metamorphosis of the Castle into the Temple of Concord.”
This change, says a writer in “The Times” of the period, “was made
with somewhat less celerity than those witnessed in our theatrical
pantomimes. It resembled rather the cautious removal of a screen than
the sudden leap into a new shape. When fully developed, however, it
presented a spectacle which excited general approbation.”

The Temple of Concord was an elaborate structure illuminated with
coloured lamps, and decorated with gilding, festoons, etc., and
transparent paintings. It was designed by Smirke, the paintings being
by Stodard, Howard, Hilton, and others, and represented such subjects
as “The Golden Age,” and “Peace restored to Earth.”

Charles Lamb, in a letter to William Wordsworth, dated August 9th,
1814, after describing the havoc wrought in the park by the crowds
and booths, remarks that: “After all the fireworks were splendent—the
Rockets in clusters, in trees and all shapes, spreading about like
young stars in the making floundering about in space (like unbroke
horses) till some of Newton’s calculations should fix them, but then
they went out. Anyone who could see ’em and the still finer showers of
gloomy rain fire that fell sulkily and angrily from ’em, and could go
to bed without dreaming of the Last Day, must be as hardened an Atheist
as ****.”

St. James’s Park was reserved for those who paid for admission. The
trees were illuminated with lamps, and a Chinese bridge, which had been
erected over the lake, was similarly treated. The use of gas on this
structure must be one of the earliest occasions of its being employed
for outdoor illuminations of this nature. Neither can the result be
considered altogether successful, as the building caught fire towards
the end of the firework display, and a lamplighter, who appears to
have been caught by the flames in an attempt to throw himself into the
water, was killed. Other men similarly employed were also severely
burned. These men, evidently through ignorance, had started lighting
the lower lamps first, working upwards on the structure, until they
found themselves in a position of intolerable heat with no means of
descending.

The pyrotechnic display consisted chiefly of aerial fireworks with
gerbs, roman candles, fountains, and wheels; there do not appear to
have been many devices of any size. “The Times” reporter complains that
“the repetition of these things, with occasional pauses, for more than
two hours became tedious to all.”

The coronation of George IV, in 1821, was celebrated by a display
in Hyde Park, including land and water fireworks, superintended by
Congreve. The displays on the coronation of William IV, in 1831, were
directed by Congreve’s successor, Sir Augustus Frazer, but appear to
have been of an insignificant character.

Queen Victoria’s coronation was celebrated by displays in Hyde Park
and Green Park, conducted by Southby and D’Ernst, which exhibitions
included a Temple on similar lines to that of 1814.

In France, during the first few years of the nineteenth century, there
were many pyrotechnic displays of importance. Napoleon is credited
with being extremely partial to such exhibitions. Displays took place
in Paris in the Champs Elysées, at the barriere Chaillot, before Les
Invalides in 1801 to celebrate the foundation of the Republic, and in
the following year in honour of Napoleon’s arrival in that city.

Major-General Lord Blayney, who was captured by Napoleon’s troops in
the Peninsula in 1810, travelled on parole across Spain and France on
his way to Verdun. His somewhat leisurely journey of nearly six months
enabled him to witness many celebrations of French victories in the
towns through which he passed. He records having seen fireworks and
illuminations among other places at Malaga and Orleans.

In 1804 a display was given by Napoleon before the Hotel de Ville,
Paris, on his assumption of the title of Emperor of the French. The
scenery provided for this display took the form of a representation
of Mount St. Bernard, with a figure symbolising Napoleon mounted on a
charger on the summit.

This display was repeated in 1810 on the occasion of his marriage with
Marie Louise; this time, however, the topmost feature was the Temple of
Hymen, with figures of Napoleon and his bride.

Other displays were given on the bridge of Louis XVI, which appears
to have been a popular position for such exhibitions, in 1800, 1804,
1806, 1820, and 1821. Another site frequently used for displays was the
garden of the Senate, where Ruggieri fired displays in the years 1801,
1806 (twice), and 1807.

Fireworks continued to be a national institution in France,
irrespective of the form of government. Louis Napoleon, like his uncle,
being fond of fireworks, or it may be, considering them a good means
of gaining popularity, made any public event an excuse for pyrotechnic
displays. Notable occasions were the Military Fetes, 1852, the Fete of
the Emperor, 1853, the visit of Queen Victoria to the Paris Exhibition
of 1855, in honour of which a most elaborate display was given at
Versailles, the Baptismal Fetes in 1856, the triumphal entry and the
Emperor’s birthday, 1859, and the visit of the King Consort of Spain in
1864.

The Entente Cordiale movement in 1868 was responsible for displays in
the Fleets on both sides of the Channel, those in France taking place
in Cherbourg, those in England at Spithead.

A previous event which had been celebrated pyrotechnically on a large
scale in both countries was the Peace Rejoicing at the conclusion of
the Crimean War.

This occasion was marked in London by four displays of fireworks on a
scale hitherto unprecedented. The sites chosen were Hyde Park, Green
Park, Primrose Hill, and Victoria Park. They were arranged thus with
the very sensible idea of splitting the crowds of sightseers into
sections and thus preventing dangerous crowding to one spot. The
fireworks were prepared for these displays in Woolwich Arsenal, under
the direction of Mr. Southby, the pyrotechnist of the Surrey Gardens,
who went there for this event.

The programmes of these displays were precisely similar, with the
exception of that at Primrose Hill, which consisted mainly of aerial
fireworks.

Tyrrell, in his “History of the War with Russia,” gives the following
account of the display in Green Park: “At the appointed signal there
was a continuous discharge of maroons, accompanied by brilliant
illuminations with white, red, green, and yellow fires.... Then for
two hours followed every conceivable design of elegant and dazzling
pyrotechnic art. Flights of rockets a hundred at a time; revolving
wheels, sun star and golden streamers, and fiery serpents chasing each
other through the air. Gerbs, Roman candles, tourbillions, shells, and
fixed pieces of the most fantastic designs and brilliant hues. The
eyes were dazzled by the intensity of the light.... It was strange to
believe that so fierce and ungovernable an element as fire could be
rendered so delicately obedient to the will of man.... The triumph,
however, of the entertainment was reserved for the close of it. This
was a tremendous bombardment, during which the air was constantly
filled with flights of rockets, and was intended as a representation of
the last grand attack upon Sebastopol—the blowing up of the magazines
and works, and general conflagration.

“As an introduction to this there were five fixed pieces, all of
complicated construction, the centre being an enormous one which, amid
all its fantastic blazing and revolving, exhibited the words ‘God Save
the Queen.’ Language fails to convey a vivid idea of the deafening,
roaring, crashing and grand appearance of the termination, during which
the proud fortifications of Sebastopol were supposed to succumb. Then
rose up into the blackness, rapidly one after another, six flights
of rockets, comprising altogether no less than ten thousand of these
beautiful and brilliant instruments.... It was such a spectacle as man
could not reasonably expect to witness more than once in a lifetime.”

This account appears to be somewhat highly coloured, as the official
programme makes no reference to the fall of Sebastopol, but it is
evident from it that the writer was greatly impressed with the display,
and contemporary prints indicate that he was voicing popular opinion.

It is worthy of note that these celebrations were the first occasion of
the kind in which the exhibitions consisted of veritable fireworks
without extraneous matter in the form of scenery and buildings. This
may account for the fact that there was, on this occasion, considerably
less of the usual outcry against the “waste” involved. It is curious
that on occasions of this kind there are always to be found certain
damp spirits who begin a clamour against the expenditure of money on
fireworks which might be applied to other objects. The Aix-la-Chapelle
display excited these gentlemen to a great pitch, probably on account
of the elaborate nature of the preparations, which, as we have already
seen, occupied over five months, thus providing them with plenty
of time to develop their theme, or an object lesson to prove their
statements.

  Fireworks at Versailles. From a drawing by Gustav Doré in “The
  Illustrated London News.”]

Where, however, the display consists—as on the occasion under
consideration—solely of fireworks proper, a few days’ preparation on
the actual site is usually sufficient; the kill-joy has less time
to spread himself. It may be mentioned his season is over with the
display; generally the British public, having enjoyed itself, turns a
deaf ear to those who would convince it that it ought not to have done
so.

Other displays took place in various parts of the kingdom: in Edinburgh
on Arthur’s Seat, at Portsmouth on the Fleet, to mention two only.

An interesting event which took place on the 25th August was the
entertainment of 2,000 men of the Guards at the Surrey Gardens. This
resort was at the time the home of British pyrotechny, the displays
being conducted by Southby, who, as we have said, went into Woolwich
Arsenal to assist in the production of the fireworks for the official
displays. The amusements of the day concluded with an exhibition of
fireworks.

A further event connected with the foregoing celebration was the
festivities in Moscow on the occasion of the coronation of the Emperor
Alexander II, which concluded with a pyrotechnic display.

From this time until the end of the century the history of pyrotechny
in this country is practically the history of pyrotechny at the Crystal
Palace; it has been the Crystal Palace displays which have set the
pace, as it were, to pyrotechnists in this country, and has provided
the spur which has placed British pyrotechnists not only ahead but
markedly ahead of their competitors in other countries.

The Crystal Palace displays became a national institution, and any
public event worthy of such recognition was accorded a pyrotechnic
celebration there on a scale hitherto unattempted.

The credit for the original introduction of fireworks at the Crystal
Palace must belong to the late C. T. Brock, who succeeded in inducing
the Directors to institute a competition among pyrotechnists in 1865.
It may be interesting to give in his own words an account of the
matter, taken from an article written by him some few years later:

  “It occurred to me that of all the places of public resort suitable
  for the inauguration of a new era for pyrotechny, none offered
  such glorious advantages as the Crystal Palace, then at the height
  of its popularity. Its terraces, fountains and foliage offered
  unrivalled advantages for the display of grand effects. The
  Directors of the Crystal Palace Company, who had more than once
  been applied to for permission to hold displays in the grounds,
  feared that, inasmuch as fireworks had been recently associated
  solely with gardens of the Cremorne class, the Palace itself would
  be degraded to the same rank if consent were granted. I urged that
  the Exhibition of 1862 had afforded no opportunity for competition
  among firework makers—necessarily excluded by the nature of their
  trade—although almost every other branch of manufactures were
  embraced, that such a contest might with reason and advantage be
  held at Sydenham, and that fireworks were really not of an immoral
  tendency. I further agreed that in the event of the result being
  unfavourable, either financially or from a social point of view,
  no second display need take place, but if, as I felt confident,
  there should be a large attendance of the better classes, then
  other exhibitions might follow. The Directors, after many months of
  delay, consented to make the experiment, and the favourable result
  of the trial on July 12th, 1865, far exceeded my most sanguine
  expectations.

  “The result was an unlooked-for success, 20,000 people being
  present on the occasion. Three more displays took place that year
  upon a small scale, but always with successful results.

  “The first display was produced jointly by my father and Mr.
  Southby, the winner of the first prize, and continued to the end of
  that season by my father alone under my management.

  “The success of fireworks at the Crystal Palace having become
  an accomplished fact, I built extensive works at Nunhead, and
  commenced manufacturing on a scale never previously dreamt of in
  the trade—the vast expanse of the locale of my displays obviously
  necessitating extraordinary expenditure of material.

  “By degrees the set pieces grew from twelve feet in diameter to 300
  feet. Shells for which the Crystal Palace has been renowned grew to
  one hundred times more than the ordinary shells of my early days,
  and thousands of pounds weight of material was gradually introduced
  to increase the effectiveness of these displays.”

  Aix-la-Chapelle, 1749.]

The Crystal Palace displays carried out by C. T. Brock and his
brother, Arthur Brock, who succeeded him in the business on March 25th,
1881, have since become proverbial. They continued up to 1910, when
the Crystal Palace was taken over by the promoters of the Pageant of
Empire. They have been revived in 1920, when the War Museum was opened,
and the attendance has proved that the public taste for fireworks is
very far from diminishing.

During the run of forty-five consecutive years an installation was
built up, method and technique were evolved unknown in any other place
of pyrotechnic exhibition.

While the firework terrace, with its magnificent background of park
and shrubberies, is unrivalled as a firing ground, it is at the same
time the most exacting. The huge building, its imposing position and
setting, the wonderful fountains, all demand pyrotechnic effects on a
corresponding scale.

The pictorial set pieces, originally introduced by C. T. Brock in 1875,
increased in size until a plant was arrived at capable of exhibiting a
picture ninety feet high and two hundred feet long on the main girder,
which length could be extended to even six hundred feet of frontage, as
on the occasion of the exhibition of a battle piece or similar subject.

During this period the subjects dealt with in the main set pieces have
covered a wide range. A favourite subject, and one lending itself
particularly well to pyrotechnic production, is the sea battle. Almost
every historic naval engagement of sufficient size to warrant its
adoption has been proved the subject for a fire picture.

Among the battle pictures produced are the following:—Bombardment of
Alexandria in 1882, Siege of Gibraltar in 1883, Battle of Trafalgar
in 1884; during 1885, two pictures representing the use of the
ironclads of the period and based on the Naval manœuvres, entitled
the “Attack on Dover,” and the Battle of Bantry Bay; the following
year another imaginary picture depicting an attack by torpedo boats on
the latest battleship, the “Colossus.” The Bombardment of Sebastopol
was reproduced in 1887, followed by the Jubilee Naval Review at
Spithead. In 1888 the defeat of the Spanish Armada was depicted;
in 1890 Trafalgar, followed in 1891 by the engagement between the
“Chesapeake” and the “Shannon,” together with a portrait of Admiral
Sir Provo Wallis, then aged one hundred, and another from an early
painting showing him at the time of the engagement when the command
of the English vessel devolved upon him owing to the casualties among
the senior officers. Later in that year the Battle of the Nile was
reproduced; 1893 saw the Bombardment of Canton; 1894 the Battle of the
First of June, and the Battle of the Yalu. The Battle of Manilla Bay
was produced in 1898, and on the centenary date the Battle of the Nile.
In 1889, H.M.S. “Implacable” was shown in action on the day on which
she was commissioned, followed in 1900 by the Bombardment of the Taku
Forts, and in 1901 by the immortal sea fight between the “Revenge”
and the “Fifty-three.” In 1904 the Russo-Japanese War gave subjects
in the various attacks on Port Arthur and the Battle of Tsu-Shima,
and the Battle of the Sea of Japan in the year following. The Battle
of Trafalgar was renewed that season, and in 1908 another imaginary
picture portraying modern naval warfare was produced, followed in 1909
by an imaginary encounter between the first Dreadnought and other craft.

The revival of the Crystal Palace displays in 1920 saw the reproduction
of the Battle of Jutland, of which the following appreciation appeared
in the Press:

  “The chief set piece in the programme is a Fire Picture of the
  Battle of Jutland, the most realistic spectacle ever produced
  in fire; by ingenious devices the guns fire, shells burst in all
  directions, gaping holes appear in the sides and upper works
  of the ships engaged, until—when the din of battle has reached
  its height—the German cruiser ‘Lutzow’ blows up and sinks. One
  realises that here at least is one pictorial subject in which
  the Cinematograph is hopelessly outdone; the variety of noises,
  varying from the sharp bark of quick-firers to the boom of the
  heavy guns, which are here so wonderfully reproduced, are quite
  inadequately rendered by the conventional thumps on the big drum in
  the orchestra.”

Before the resources of lance-work were fully understood, the
reproduction of famous buildings was a fruitful source of subjects;
those reproduced vary from the Crystal Palace itself to Worcester and
Salisbury Cathedrals, and from the Arc de Triomphe to the Mosque at
Delhi.

Natural catastrophes such as the Avalanche, the Eruption of Vesuvius,
and the Destruction of Pompeii have been portrayed. The Wreck of the
Eider in 1892, with the rescue of the passengers by the lifeboats,
formed the subject of a popular set piece; another successful scenic
showed a wreck with line-throwing rockets and transport of passengers
by the breeches buoy.

In 1879 portraits in fire were reproduced for the first time, and since
that date those executed have included almost all the Royal Personages
of the day, many of which have been fired electrically from the Royal
Box by the originals. Other eminent people reproduced range from King
Cetewayo in 1882, the Maori King in 1884, Li-Hung-Chang in 1896, to
Douglas Fairbanks and Mary Pickford in 1920.

In 1887 what is known as the transformation set piece was introduced.
Upon lighting, the piece exhibits a floral design in colours, which,
after burning some time, becomes transformed into a portrait, the lines
of which are worked inconspicuously with those of the floral design,
and, to use a modern term, camouflaged by its colours, the colour of
the portrait being white.

[Illustration: A full-size picture of the Jumma Musjid in Fireworks
  at the Crystal Palace, 1892.]

[Illustration: Firework Display for the Coronation Durbar at Delhi,
  January 3rd, 1903. In the background is the Jumma Musjid.]

The first portrait to be so shown was Lord Beaconsfield, the floral
design being of primroses, and the occasion Primrose Day. This, for
the first example of its kind, was very successful, and later in the
year an enormous transformation picture, 200 feet long and 100 feet
high, was fired at the Jubilee display, changing to portraits of Queen
Victoria and members of the Royal Family.

A popular picture of this kind is the puzzle picture which transforms
from a jungle scene to animals.

Another most successful changing picture was entitled “The Seasons,”
first produced in 1889, and revived from time to time. A rural scene
changes from Spring to Summer, from Summer to Autumn, and finally to
Winter. The effect is produced by varying compositions in the lances,
and by employing lances of varying length, and requires very exact
manipulation and supervision.

Patriotic, congratulatory, and political cartoons and devices have been
exhibited in wonderful variety of design, sentiment, and language:
Chinese, Persian, and Maori, to mention only three of the latter.

Living Fireworks, invented and patented by C. T. Brock and Co., in
1888, have always been a favourite feature of the Crystal Palace
displays. The performer is clad in overalls of asbestos cloth, and on
the side nearest to the spectators wears a light wood framework, of
which the outline is “lanced” to depict the particular character to be
portrayed.

The first subject dealt with was the boxing match, which has enjoyed
continuous popularity up to the present day, and is possibly the most
successful.

Other favourites have been Blondin on the tight rope, inspired by the
appearance of the real Blondin on the firework terrace, surrounded by
firework effects, in 1871; dancers of various kinds, from the Sailor’s
Hornpipe to Salome; Cat fights; Cock fights; the Boxing Kangaroo in
1893, when that performance was attracting crowds to the old Aquarium;
an Indian Snake Charmer; a Fisherman; a Trapeze Artist, have all been
produced by living actors in fire.

In 1895 “The Village Blacksmith” was enacted, with horse, blacksmith,
assistant, and horse’s owner, with forge, bellows, anvil, and all
necessary “properties.” The following year a piece was exhibited
showing various members of the building trades at work. Then followed
the Fire Scene, in which a house is seen on fire, the motor fire engine
arrives, the men jump down, unroll the hose, and proceed to extinguish
the outbreak with a jet of fire. Another ambitious effort showed a
City policeman regulating the traffic. The most elaborate scene of the
kind yet attempted was to work living figures in connection with the
main set piece. The subject chosen was life in the Arctic Regions, and
opened with the open Polar Sea, with whaling vessels, spouting whale,
and launch of the whaling boat, which follows the whale and fires a
harpoon. The picture then changed to Arctic winter, ice forms, and
the vessel is frozen with the ice, sledging parties travel over the
ice, and the picture concluded with a man and bear fight in living
fireworks. The same year—1890—there was introduced into the Children’s
Fireworks, which form an annual feature of the Crystal Palace displays,
a living Jack and the Beanstalk picture.

In 1906 the then popular song, “I wouldn’t leave my little Wooden Hut
for You,” was the basis of what was described in the programme as a
Living Firework Drama. The popular songs of the day have provided
the subject for many successful set pieces, and form a class of picture
which derives much of its success from the band accompaniment and the
opportunity for vocal effort on the part of the crowd.

[Illustration: A Crystal Palace Set Piece at the time of the South
  African War. (200 ft. long by 70 ft. high.)]

The origin of this type of picture is worth recording. In 1889 the Shah
of Persia visited the Crystal Palace, and fired a portrait of himself,
electrically, from the Royal Box. A popular song of the day, “Have you
seen the Shah?” was suggested to some musically inclined members of the
audience, who commenced to sing it, and were soon joined by the whole
of the spectators, numbering about 50,000.

The effect of this impromptu concert was so striking as to lead to
the production of the popular song whenever there happened to be one
suitable for pictorial rendering in fireworks.

In 1892 a mechanical Lottie Collins, 60 feet high, dancing to the then
popular strain of “Ta-ra-ra-bom-de-ay,” was enthusiastically received.
A series of patriotic and sentimental songs at the time of the South
African War, as “The Absent-minded Beggar” and “Good-bye, Dolly Grey,”
etc., were very successful. The “Honeysuckle and the Bee” provided the
subject for a transformation picture, a design of honeysuckle changing
to a girl’s head with a mechanical bee twelve feet long.

In 1908 three songs were included in one piece—“Bill Bailey,”
“Farewell, my Bluebell,” and “The Old Bull and Bush.”

The smaller mechanical pieces form a history of locomotion during the
half-century covered by the displays. Bicycles, motor cars, looping the
loop, aeroplanes, costers’ barrows, hansom cabs, fire engines, scooters
have all been represented, and in 1895, on the occasion of the visit of
the Railway Conference, two of the best mechanical pieces ever carried
out—full-sized representations of the “Rocket” and the latest type of
express engine with exact details and working parts.

An effective working device introduced as early as 1870 was a comet
travelling down a wire from one of the famous towers to the ground.
Later the comet was replaced by a dragon, Mother Goose, and in 1872 by
a “Fiery Bicycle,” a subject which seems somewhat out of place in such
a position. The next development of this feature was to introduce a
living man who, clad in shining armour and surrounded and illuminated
by a frame of fireworks, striking an impressive attitude, slid from the
summit of the tower to the terrace.

The name of this performer, no doubt in imitation of the Italian
artists who on a smaller scale carried out a similar feat at Vauxhall,
was given in the programme as Signor Gregorini. In private life or in
the works, however, he went by the name of Bill Gregory, and it is
recorded that, when on the first night he stuck half-way down and had
to remain in his airy position for the remainder of the display, his
remarks left no doubt as to the country of his origin.

It is characteristic of Mr. C. T. Brock that he who originated the idea
was the first to try the descent. The weight of the cable was very
considerable and the strain very heavy in order to keep it sufficiently
taut, and doubts were expressed as to the advisability of putting
such a stress on the structure, which led to the abandonment of the
performance.

It would be tedious to attempt to give anything like a description of
the many and varied moving and stationary devices used in the Crystal
Palace displays. The descriptions in the traditional somewhat flowery
language of the firework programmes would convey little without
illustration. One feature generally to be found in the programme is
that of the wheels. These are generally fired in a group of three in
the centre of the Terrace, the designs varying in form, movement and
colour from time to time, the fire of the centre or largest wheel
forming a circle one hundred feet in diameter.

The historical displays during this period include the displays given
in India in 1875–6, during the tour of King Edward, then Prince of
Wales, at Bombay, Madura, Colombo, Madras, and Jaipur, and a series of
enormous displays carried out at the Philadelphia Centennial Exposition
in 1876, at one of which 250,000 people paid half-a-dollar admission,
and in 1877, the displays given at Calcutta and Delhi on the occasion
of the assumption by Queen Victoria of the title Empress of India.

The Jubilee and Diamond Jubilee of Queen Victoria produced enormous
activity in the manufacture of fireworks. Displays great and small took
place all over the United Kingdom, or rather, the Empire.

Among the displays fired on the occasion of the Diamond Jubilee,
certainly not the least interesting, although comparatively small
in extent, was that given at Blantyre in the heart of the African
continent. This display, which included a portrait of Her late Majesty,
was carried up three hundred and sixty miles of the Zambesi, thence by
canoe over eighty miles of sandbanks and mud, and finally thirty miles
overland with a rise of 3,500 feet.

Other displays were the display on the Tagus in 1886 on the occasion
of the marriage of the late King of Portugal; the display fired from
Brooklyn Bridge for the Columbus Tercentenary in 1892; the Imperial
Fete on the Danube in 1903; the display fired from thirteen battleships
moored at a distance of a quarter of a mile from each other on the
occasion of the “Entente Cordiale” visit of the French Fleet in 1905;
the display celebrating the Tercentenary of the founding of Quebec in
1908; and the greatest display of fireworks ever fired—the official
Peace display in Hyde Park in 1919, in which some of the ground works
suffered from the rain which, unfortunately, started about five
o’clock, but the aerial work was on an unprecedented scale, shells
varying from sixteen inches down to 5½ inches in diameter being fired
in salvoes of twenty-five to one hundred.

Rockets of 1 lb. were fired in flights of one hundred, and a final
flight of three thousand; sets of Roman candles, each containing two
hundred; one hundred fiery jets, etc., etc. The “Fourth of June”
celebration at Eton has always been the occasion of a firework display,
and displays have taken place annually, with the exception of the
years of the Great War, from at least as early as the beginning of the
nineteenth century. Hone, in his “Everyday Book” (1831), speaks of the
fireworks as a well-established feature of the festival.

It is possible, and even probable, that they date from the reign of
George III, on whose birthday the event takes place.

                              CHAPTER VII

                         FIREWORK MANUFACTURE


The manufacture of fireworks in this country, as an industry distinct
from mere firework making, dates from the early part of the eighteenth
century. Before that period displays appear to have been generally
carried out by the military, or at any rate under the control of
artillery or engineer officers. At that time the art was considered to
have two distinct branches, civil and military pyrotechny, the latter
class naturally attracting most attention during a period when Europe
was almost continuously at war, and when firearms had made little
progress from the early types.

As has been previously mentioned, Jones complains that when it was
required to carry out a display of fireworks on a large scale, recourse
was always had to foreigners to conduct it. One reason was that, apart
from the actual making of the firework units, a display depends far
more for its success on the experience and skill of the pyrotechnist in
arranging and composing both the form and sequence of the pieces. The
firework makers capable of carrying out a display on a large scale were
very few; there were fewer, if any, in this country. The whole of the
trade was illegal; under the statute of the 9th and 10th of William III
it was illegal to make, sell, or let off fireworks:

  “By the 9th and 10th of William, Chap. 7, it is enacted: That if
  any Person shall make or cause to be made, or sell, give, or utter,
  or offer, or expose to sale any Squibs, Rockets, Serpents, or other
  Fire-works, he shall forfeit Five Pounds. And that if any Person
  shall permit the same to be fired from his House or Premises, or
  shall cast or fire, or be aiding and assisting in casting or firing
  the same in any public Street, House, Shop, River, or Highway, he
  shall forfeit Twenty Shillings, or be committed to the House of
  Correction to hard Labour for one Month.”

This Act continued in force up to the passing of the Gunpowder Act in
1860. There were periods during which it was practically a dead letter,
and again periods of sporadic activity.

The first restriction of the public use of fireworks appears to
have been an order in council dated November 6th, 1685, which
“For the preventing of Tumultuas Disorders” and with the object
of “Disappointing the Evil Designs of Persons Disaffected to the
Government, who commonly make use of such occasions to turn those
Meetings into Riots and Tumults,” enacted that “No Person or Persons
whatsoever, do presume to make or encourage the making of any Bonfires,
or other Publick Fire Works—without particular permission Leave in
Order—upon Pain of His Majesty’s Displeasure; and being Prosecuted with
the utmost severity of the Law.”

A notice appeared in the press of November 1st, 1788, dated from the
“Public Office, Bow Street,” warning the public against firing crackers
in the street, and quoting the Act “that no Person may claim Ignorance
thereof.” Again, in 1814, “The Times” has an account of a summons under
the Act of a William Swift, “for exposing for sale, Squibs, Serpents,
Crackers and Fireworks of other descriptions to the great danger and
annoyance of the public and contrary to the Statute.” The report
continues:

  “Mr. Laws in opening the case observed, that this was a prosecution
  brought forward at the recommendation of the Magistrates of
  Union-Hall, who, however, did not by it seek to punish the
  defendant with severity but only to inform him and others acting
  like him, that the Act upon which the present indictment was
  founded and which so far back as the reign of William III, was
  passed for the protection of the public, though it had not
  lately been acted upon, was still in force. The defendant, it
  appeared, was a man of property and a respectable holder residing
  in Falcon-Court, where he had for some time past carried on the
  profession of a firework-maker. The officers of Union-Hall having
  heard, however, that he was in the habit of supplying boys or
  any person who applied indiscriminately with these dangerous
  commodities, they determined, if possible, to put a stop to this
  traffic, so dangerous to the public safety. For this purpose they
  sent a person, properly instructed, to purchase some; Goff, Bruce,
  and some other of the officers remaining near the door to detect
  him coming out; the purchase was made, and as the purchaser was
  quitting the house, the officers stopt him and forced their way in.
  They proceeded to search the premises, and concealed in closets
  and other parts, they discovered a vast quantity of fireworks of
  various sizes and descriptions, amounting to 19,600 and weighing
  upwards of 6 cwt., several of these, singly, were large enough to
  have spread ruin through the neighbourhood, had they by accident
  exploded. These the officers took away and deposited at the Office,
  where they still remained to the great annoyance of the Magistrates
  waiting the decision of this question.”

Hone, in his “Everyday Book,” records that at that time, 1825, “A
Corporation notice was annually left at the house of every inhabitant
in the City of London, previous to lord mayor’s day.” The following
(delivered in St. Bride’s) is its form:

                                         “_October the 11th, 1825._

  Sir:

  By Virtue of a Precept from my Lord Mayor, in order to prevent any
  Tumults and Riots that may happen on the Fifth of November, and the
  next ensuing Lord Mayor’s Day, you are required to charge all your
  Servants and Lodgers, that they neither make, nor cause to be made,
  any Squibs, Serpents, Fire Balloons, or other Fireworks, nor fire,
  fling, nor throw them out of your House, Shop or Warehouse, or in
  the Streets of this City, on the Penalties contained in an Act of
  Parliament made in the Tenth year of the late King William.

  Note. The Act was made perpetual, and is not expired, as some
  ignorantly suppose.

                                           C. Puckeridge, _Beadle_.

          Taylor, Printer, Basinghall Street.”

During the period of the operation of the Act, that is from the end
of the seventeenth to the middle of the nineteenth centuries, on the
occasion of public rejoicing, the authorities were in the anomalous
position of employing persons to break the law, both by manufacturing
and displaying fireworks.

Although, as we have seen, this Act had very little effect on the
quantity of fireworks manufactured, it had considerable adverse effect
on the industry. As the whole thing was illegal, no regulations were
framed to control the making, storage, or distribution of fireworks, or
the safety of either workers or public. The manufacture was conducted
on lines which, at the present time, appear inconceivably reckless.
Several people working in one room in a crowded building, with loose
composition and gunpowder, and a fire in an open grate round which
finished or partially finished goods were put to dry, and this in a
thickly populated area of London.

The result of this state of affairs, as might have been expected, was a
continuous series of explosions of a more or less serious nature.

An early press account, dated 1722, relates to “Mr. Goodship of
White Alley in Chancery Lane,” and continues, “as he was making some
fireworks, the Gunpowder took fire and blew him up, by which means the
House was fired, and that adjoining somewhat damaged. More Mischief
had been done, but that there was timely help. The Man is so hurt that
his life is despaired of.” Another account gives the man’s name as
Goodsheaf.

The early part of the nineteenth century provided an extraordinary list
of accidents.

In 1810 we find the following account of an accident at Bath:

  “On Monday a dreadful accident happened at Bath to Mrs. Invetto, a
  firework-maker, and a young man her assistant. They were preparing
  sky-rockets, etc., for the Jubilee, when, by some means, an
  explosion took place of a considerable quantity of powder, some say
  upwards of two hundred barrels, which blew the house, and another
  adjoining, to atoms. The unfortunate woman was miserably burnt and
  bruised; and no hopes are entertained of her recovery. The poor
  fellow also lies in a shocking state at the Casualty Hospital at
  Bath.”

In 1814 two accidents are recorded to Mortram and Clithero. The former
took place in the “Westminster Roade, near the Asylum”; a man and two
boys were very badly burned, two succumbing to their injuries the
same day. Clithero’s establishment was situated in Fleet Street Hill,
Bethnal Green. The accident here was caused by fire from the steam
engine reaching some fireworks. Three people were badly injured, and
much glass was destroyed in the neighbourhood. Clithero appears to have
had his works separate from the dwelling-house, an arrangement which
appears to be the exception rather than the rule. Mortram’s premises
were again destroyed in 1818, fortunately without loss of life.

A serious accident took place in 1815, in which five people lost their
lives, the premises, and those on either side, being demolished, and
nearly all windows destroyed within two hundred yards. The proprietor
of the premises, which were situated at Wilkes Street, Spitalfields,
was Lushalan.

In 1821 a third accident occurred at Mortram’s works, the newspaper
account of which gives an illuminating glimpse of the extraordinary
methods of the period:

  “Tuesday morning an accident, which occasioned considerable alarm,
  and might have been attended with dangerous consequences, took
  place in the house of M. Mortram, firework-maker, in Westminster
  Road. It appears that one of the boys employed in making
  composition stars for rockets had placed a number of them on the
  fender before the fire to dry, and had set fire to one on the
  hob, which falling in amongst the others, the whole exploded, by
  which a little girl was much hurt in the back, and so frightened
  that she ran to the window of the first floor, but was prevented
  jumping out. The boy escaped up the area with his jacket on fire.
  The neighbours were now much alarmed, fearing that the fire might
  spread to more combustible matter in the house, and so on to the
  extensive workshops of Madame Hengler, the celebrated pyrotechnic
  to his Majesty; but, through the activity of the workmen, who ran
  into the adjoining house with buckets of water, further damage was
  happily prevented, or the consequences might have been dreadful.
  An accident of a shocking nature, it will be recollected, occurred
  about three years since in the same person’s repository, when two
  men were killed by the explosion.”

In 1825, in Bell’s “Weekly Messenger” of September 4th, appears the
following account:

                  “DREADFUL EXPLOSION IN WHITECHAPEL.

  “Yesterday morning, about half-past eight o’clock, Whitechapel
  Road, and the numerous streets that abound there, were thrown into
  the greatest state of agitation, by the inhabitants experiencing a
  most tremendous shock, as if caused by a volcano or an earthquake.
  The houses for a considerable distance were deserted by their
  inhabitants, and men, women, and children were seen running about
  in all directions, under the impression that the world was at an
  end. It was soon ascertained that their alarm was produced by the
  explosion of the factory of Mr. Brock, the artist in fireworks, at
  No. 11, Baker’s Row, Whitechapel Road, nearly opposite the London
  Hospital.

  “The following particulars relative to this direful disaster
  have reached us:—Mr. Brock has resided for the last five years
  in Baker’s Row, and at the back of his dwelling-house is his
  repository for fireworks, where they are manufactured. This
  building is about 50 feet by 20 feet, and contains three magazines,
  which are lined with lead, and would be perfectly secure from
  fire, should it occur, on any of the adjoining premises. In these
  receptacles were deposited all the powder, composition, and, in
  fact, all the combustible matter, and Mr. B. was remarkable for
  the method he had taken to prevent any accident occurring on his
  premises. A few weeks since he had taken two boys out of the
  poor-house to instruct in the art of firework making and he kept
  them chiefly employed in filling and ramming the cases of the
  sky-rockets, serpents, squibs, etc. The latter part of this stage
  of the work is done by a funnel, or piece of tin made in the shape
  of an extinguisher, and a small piece of iron wire, about a foot
  long, which is used as a ramrod. The small end, or nipple, as it
  is called, of the extinguisher is introduced into one end of the
  rocket or squib, and the boys ram the powder and wadding down
  with the ramrod. Yesterday morning, at the time above stated, Mr.
  Brock and his men left the factory to go to breakfast, leaving
  the two boys engaged at the work-board, ramming the sky-rockets.
  They had scarcely sat down to their meal when they, as well as
  the inhabitants around them for some distance, heard a sort of
  rumbling noise as if of some distant thunder, and the next moment
  a tremendous and deafening explosion followed, and the air was
  illumined with lights of various descriptions, and accompanied by
  continued reports. The concussion thus occasioned was so great that
  the inmates in the different houses were shaken from their seats,
  many of whom were sitting at their breakfast, and the tables and
  tea-things were upset and broken to pieces. The window frames were
  all forced out, and the brickbats and materials were flying about
  in every direction. The roofs of Mr. Brock’s manufactory, and the
  factory of Mr. M’Devitt adjoining, were blown to a considerable
  height, and the falling materials did considerable mischief. After
  the agitation was somewhat subsided, an inquiry into the cause of
  the accident took place, when it appeared from the statement of
  the two boys (who were blown a considerable height and were much
  injured) that they were at work, ramming the rockets, when the
  ramrod struck against the funnel, and the friction caused a spark,
  which flew into the bowl of gunpowder that stood near them; this
  soon exploded, and ran like a train to all the other fireworks in
  the factory, and at length communicated to the magazines, which
  caused the disaster. Mr. Brock, however, declares that it could not
  have arisen in that way, as the nipple of the funnel was copper,
  therefore a friction would not cause a spark. One poor woman,
  sister to the beadle, who lives next door to Mr. Brock, was so
  dreadfully injured by the broken glass that she lies in the London
  Hospital without hopes of recovery. Ten houses were seriously
  damaged, and over sixty had their windows broken from top to
  bottom.”

It will be seen from the foregoing that Brock was in advance of his
time as regards precautions against explosions, which, however, in this
case proved to some extent ineffective.

An accident took place in 1838 at the premises of Cockerill, in
Paradise Row, Lower Road, Islington. Three persons were killed, and the
proprietor was so severely hurt in an attempt to rescue his family that
he died later.

The following year an accident took place at 6 Edward Street, Bethnal
Green, in which three persons were injured. The explosion was caused
by a spark from the fire falling on a quantity of loose powder lying
on the table, the flash from which was communicated to a barrel of
powder near. The report continues: “The most miserable negligence was
displayed by the persons engaged in the fabrication of the fireworks,
as just previous to the accident one of the individuals was making a
squib by the fire with a lighted pipe in his mouth.” The pyrotechnist’s
name is not recorded.

An explosion took place in 1841 at 6 Hatfield Place, Westminster Road,
Lambeth, at the works of Drewett. Considerable damage was done, but
fortunately no one was injured.

In 1857 Darby’s factory at 98 Regent Street, Lambeth Walk, was
destroyed. The upper part of the house was used as bedrooms, with the
stock below; the whole of the premises and stock were destroyed, the
occupants of the bedrooms, who were cut off, being rescued by the
aid of ladders. On this occasion the gunpowder appears to have been
stored in a magazine away from the house. The report adds that the
same premises had suffered in a similar manner on one or two previous
occasions, and subsequently, in November, 1873, a disastrous explosion
at the same premises resulted in the loss of no fewer than eight lives.
In 1858 a serious explosion took place at Madame Cotton’s factory in
the Westminster Bridge Road.

The above-mentioned accidents do not comprise anything like a complete
list, but tend to show the lines on which the manufacture of fireworks
was conducted during the period covered.

The frequency of such occurrences and the danger entailed to third
parties pointed to the necessity of action of some kind. The old Act
might have been put into force, but by so doing the industry would be
stamped out, an industry which found employment for a large number of
workpeople, and besides giving amusement and entertainment to many,
provided signal lights and rockets, the demand for which was steadily
increasing.

There were at this time a considerable number of firework makers in
London, particularly in the east and south of the Thames. Much of
the work was given out to the workpeople’s families to make up in
their own homes. Workmen now living can remember, as children, seeing
crackers, squibs, and other small goods being manufactured in bed and
living-rooms of tenement houses in crowded districts, with open fires
in the grates and several pounds of powder in a corner of the room.
The materials were either given out at the factory and a piecework
rate paid for making up, or the workers bought their own materials at
the local shops, which in these districts kept what was required, and
sold them to the factory on completion. It was then a common practice
for a maker who had completed a “frame” of quickmatch to take it round
to the local bakehouse to be dried and called for in the morning.

Considered from the point of view of modern practice, the wonder is
that there were not more accidents than actually took place.

The Gunpowder Act of 1860 was an attempt to place the manufacture and
storage of explosives generally on a more satisfactory footing. It laid
down regulations to be “observed with regard to the manufacture of
loaded percussion caps, and the manufacture and keeping of ammunition,
fireworks, fulminate of mercury, and any other preparation or
composition of an explosive nature”; and makes it lawful for Justices
of the Peace in Quarter Sessions to license places for the manufacture
and storage of such articles, and to grant licenses to persons to sell
fireworks.

It also provided for the installation of lightning conductors in
explosive magazines.

This Act, although far from perfect, was a step in the right direction;
it had the effect of bringing some makers out from the back streets of
crowded districts, to construct properly arranged factories, or at any
rate, factories planned with some regard to their use.

Four years after the passing of the Act, public attention was sharply
drawn to the matter by an explosion on an unprecedented scale at
Erith, where several of the gunpowder manufacturers had magazines.
Enormous damage was done, and many lives lost, over an area ten miles
in radius. Lieutenant-Colonel Boxer, R.A., Superintendent of the Royal
Laboratory, Woolwich, in his report on this explosion, draws attention
to the need for a system of inspection of explosive establishments,
with the result that he was himself authorised to make such inspection.

Lieutenant-Colonel Boxer was succeeded in 1870 by Captain (afterwards
Colonel) Sir V. D. Majendie, K.C.B., who recommended the appointment of
permanent Explosives Inspectors.

The late C. T. Brock, who commenced the long run of Crystal Palace
displays in 1866, found his works insufficient for the large supply of
material required for such displays, and commenced the construction of
a factory on new lines at Nunhead. It was here in 1872 that the Royal
Commission witnessed a series of experiments, the programme of which is
here reproduced.

It was upon the results of these experiments that the provisions of
the Explosives Act of 1875, in so far as they relate to fireworks, are
based.

This Act is still in force, and is unlikely to be superseded for
many years to come. There can have been few Acts which have, since
their inception, proved so satisfactory to the industry controlled
by them, either in the results achieved, or in the manner of their
administration.

The Explosives Acts of 1860 and 1875 took the then proscribed art
of pyrotechny from back streets and crowded districts, rehoused it
in properly designed and conducted factories in rural or suburban
districts, making it as healthy and safe an occupation as almost any in
the country.

                             CHAPTER VIII

                      MODERN FIREWORK MANUFACTURE


Fireworks are now manufactured under the Explosives Act of 1875 and
Orders in Council No. 2 and No. 4 under that Act.

Order in Council No. 4 deals with small Firework Factories, the total
contents of which, either finished or in course of construction, do not
exceed 500 lbs. This class of factory presents little of interest for
consideration; and is governed by practically the same rules as are
the larger establishments of the kind, with such modifications as are
justified by the small quantity of explosive material involved.

Order in Council No. 2 sets out the general rules to be observed in
factories licensed under the Act, the leading points of which are as
follows:

The absence of iron or steel in any workshop, carriage, or boat;
cleanliness and absence of grit; care as to material liable to
spontaneous ignition; provision of lightning conductors on magazines;
tools and implements to be of soft metal; working clothes without
pockets; shoes without nails; searching or means to prevent the
introduction of matches or dangerous substances into the works;
materials and finished work to be removed from working buildings and
not allowed to accumulate when any particular process is completed;
no person under sixteen years to be employed or enter any danger
building. Every building to be provided with a set of these rules, and
a statement of the quantities of explosives and ingredients, and the
work to be carried on in it as allowed by the license.

The modern factory is generally situated in a rural district on
account of the fact that it is more easy to observe the statutary
distances from protected works. Protected works referred to in the
Act include other workshops and magazines in the factory, and also
dwelling-houses, factories, institutions, railways, highways, and
various undertakings and buildings, the distances to be observed
varying with the nature of the protected work from public highways to
palaces or houses of residence of the King, his heirs and successors.
In some cases, as with private dwelling-houses, the distance to be
observed is about half, if the consent of the occupier to the erection
of the factory building or magazine is obtained.

Firework factories, in fact all explosive factories, are constructed on
the principle of limiting the scope and effect of any explosion that
may take place to the smallest possible quantity of material and to the
smallest possible risk to human life.

The working buildings are constructed with a door at either end to
facilitate escape in case of danger; the quantity of chemicals and of
partially or wholly finished fireworks is strictly limited, as is the
number of persons employed in the building. This number varies with the
nature of the operation being carried out, from one in the case of the
most hazardous to six in some cases.

The working buildings are of light construction; the form most in use
is a timber framing lined with matched boarding and covered externally
with corrugated iron. No iron fittings are used, or iron nails left
exposed in the interior. The floor is covered with linoleum, which is
secured by copper tacks.

The distance separating working buildings is, generally speaking,
twenty-five yards, or if a suitable screen is placed between two such
buildings, this distance may be reduced to twelve yards.

The workpeople are provided with non-inflammable outer garments,
no pockets are allowed, and suitable overshoes of sewn leather or
indiarubber are provided.

All tools are of soft metal, such as brass or copper, or of wood.

The regulations refer, of course, only to those buildings in which
explosive work is carried on, that is to say, buildings in the danger
area as distinct from the non-danger area.

The buildings in the danger area are working buildings, drying-rooms,
expense and factory magazines. Expense magazines are those which are
licensed for a comparatively small quantity of explosives, and from
which explosive material is drawn as the work of the factory demands,
or into which is put partially or wholly finished work either awaiting
completion or transference to the main or factory magazines.

The non-danger area includes stores for chemicals, paper, and other
material, also case rolling and drying sheds, sawmill, wood-working and
paper-cutting shops, offices, and similar buildings.

The manufacture of fireworks begins with the making of the case or
container, which, with the exception of shells and Jacks-in-the-box,
are cylindrical in form.

What are known as “small goods” are “dry-rolled,” that is, the outer
edge of the paper only is pasted. They are then rolled up on a metal
former on a slate slab.

The larger cases, such as rockets, gerbs, and Roman candles, have
the paper pasted all over, which is rolled up on the former and
consolidated by repeated rolling between the slate slab and a board
provided with a handle.

There are two methods of introducing the composition into the
cases—filling and charging.

Filling is used where the composition does not have to be consolidated,
and is done with a wire and funnel, or as it was formerly called, a
“tun dish.” The funnel has its outlet of such a size as to fit the case
to be filled, the wire or rod is somewhat smaller than this outlet, and
is provided at the upper end with a knob for the hand. The end of the
funnel, which is filled with composition, is inserted in the upright
case. The wire is then drawn up, thus freeing a small quantity of the
composition which runs down into the case, the lowering of the wire
pushing it into position. In order to render the downward movement
more effective, the wire is often notched, but it is doubtful if this
actually increases the efficiency. This action is rapidly repeated
until the case is filled.

This method, although simple, is very effective, and in the hands of a
practised worker is exceedingly quick.

Charging is adopted where the contents have to be solidified in the
case. The composition is introduced in small quantities with a scoop of
suitable size and consolidated by repeated blows with a wooden mallet
on a “drift.” The drift is a cylindrical wooden tool of a size to fit
the case, and an enlargement at the upper end to receive the blow of
the mallet.

The methods of charging the various forms of fireworks will be dealt
with later under their separate headings.

The method of charging rockets in use in the sixteenth century are
those of to-day, and it is remarkable that no satisfactory alternative
to hand charging has yet been devised. Mechanical hammering and
hydraulic pressure have both been tried, but so far with limited
success.

Stars which are used in Roman candles and as garniture for rockets and
shells, are of many kinds and combinations, but with the exception
of some which are in effect complete miniature fireworks, they are
constructed on one of three methods—they are either “pumped,” “pinched”
or “charged.”

The pump used in the first of these operations consists of a short
metal tube, which fits exactly a short metal plunger provided with a
knob for the hand, and a small metal stud at the side. The tube has a
slot cut partially down the side to receive this stud.

The method of using the pump is as follows:—The plunger is drawn up
so that the stud rests on the top of the tube. The pump is pressed
into a heap of prepared composition, which action has the effect of
compressing the composition in the tube. The plunger is then turned
so that the stud engages with the slot, and pushed down, forcing the
star out of the tube. The composition is prepared for pumping by being
damped with methylated spirit or some other suitable solvent, and after
making, the stars are dried in specially constructed buildings.

Pinched stars are made by pinching the damped composition into a short
paper case, through which a short length of match is first passed.

Charged stars have generally a clay or cardboard bottom to the case,
and are usually matched. This form is generally used for Government
signal rockets, as the composition being only at one end of the case,
the time of burning is extended.

The mixing of compositions requires great care and thoroughness. Care
both on account of the necessity of exact adherence to the formula,
and to preclude the presence of any foreign body or chemical which,
apart from any effect it might have on the successful functioning of
the fireworks for which it happens to be used, might render it most
dangerous in manipulation.

Generally working buildings are licensed for mixing compositions, but
it is usual to set certain sheds apart for this purpose, especially if
the chemicals used are of a dusty nature, that is, very finely divided,
in which case the atmosphere becomes highly charged and dangerous.

Chlorate of potash, from the introduction of which into pyrotechny
modern effects and colours may be said to date, has at the same time
been responsible for many accidents. As will be seen in the later
chapters on firework compositions, for many years chlorate of potash
and sulphur were used freely in the same mixtures, and many as were the
accidents caused by so doing, yet it is incredible that they were not
far more numerous.

Most makers were well aware of the dangerous nature of this admixture,
but persisted in using it, as the colours so obtained were at that time
unapproached by other means; naturally no manufacturer wished to be
alone in the discontinuance of some of the most striking effects at the
time available, or to give competition the consequent advantage.

In August, 1893, a man was fatally burned whilst simply emptying a
small quantity of crimson stars from one tray to another; the slight
friction so caused was sufficient to ignite the stars and thus fire
the whole contents of the building. This unfortunate accident took
place at the works of C. T. Brock and Co., then at South Norwood, and
seems even more unfortunate when one learns that with the exception of
this particular crimson, they had practically eliminated chlorate and
sulphur colours.

The following year, by Order in Council No. 15, the admixture of
chlorate of potash and sulphur was made illegal.

Previous to this accident, during the same year and in the same works,
a serious accident involving the death of one workman and the injury of
another, was caused by a barrel of chlorate of potash being delivered
and marked nitrate of potash (saltpetre). Its use in a composition
containing sulphide of arsenic (orpiment) produced a mixture
approximately to that used in some fog signals and designed to fire by
percussion. The natural effect was the serious explosion that followed.

The late Sir Vivian D. Majendie, K.C.B., the then Chief Inspector of
Explosives, records in his report that “Messrs. Brock are extremely
careful to keep chlorate and non-chlorate mixing departments, and even
ingredients in separate buildings and under separate control,” and
while he considered that “some measure of blame is attributable to
them in respect of the defects of their system which rendered possible
the presence of a cask of chlorate of potash as “saltpetre” in the
saltpetre shed,” he adds: “It is only fair and proper that I should say
that our experience of the manner in which Messrs. Brock conduct their
large business generally is extremely satisfactory. This factory is
in many respects a model; they have always shown themselves ready to
discuss with us and adopt any suggestion tending to increase the safety
of the workpeople.”

These indications, if such were needed apart from the official
prohibition of the use of these two ingredients together, convinced
Mr. Arthur Brock that even greater care was necessary in dealing
with them. With this object in view, when the works were removed to
Sutton, Surrey, the two factories at South Norwood and Harold Wood,
Essex, being inadequate to deal with the business, the plan of the new
factory was arranged so as entirely to separate that portion of the
factory using chlorate of potash from the portion using sulphur. A road
running up the factory from the entrance gate divides it into what are
virtually two factories, known as the Colour and Bright Sides.

These works, which are easily the largest of the kind in the world,
cover an area of nearly 200 acres. They include about 60 magazines,
expense magazines, and drying rooms, with a total storage capacity of
1,300,000 lbs. of fireworks and 5 tons of gunpowder; 120 explosive
working buildings (mostly double), besides numerous stores,
non-explosive working buildings, saw-mills, and wood-working shops.
The buildings are connected by over four miles of tram-lines. The
average number of employees is 150 men and 200 women. During the late
war this number was increased to over 2,000 on the manufacture of
munitions.




                              CHAPTER IX

                          FIREWORK ACCIDENTS


The record of firework accidents until the date of the Explosives Act,
1875, is very meagre, not in subject matter, as reference to Chapter
VI will show, for the history of the industry up to that time appears
to have been one catalogue of accidents; the only cause for wonder
when one considers the conditions then prevailing is that there were
not more. But in detail, the only records are more or less sensational
reports of the event, and such explanation of the cause as the reporter
could pick up from some bystander.

In some cases where the workers were not killed the explanation was
found to be simple; as for instance, the accident at Mortram’s works
in 1821. Here a boy who was making stars in a room with several other
workers and other composition present, put some of his work to dry
before the open fire, and as if this was not a sufficiently reckless
proceeding, lit one on the hob, with the consequences that were to be
expected.

In most cases, however, the cause seems to have been obscure, and
little or no trouble appears to have been taken to discover the cause
with a view to prevention of a repetition.

Since the Explosives Act careful record is kept of all accidents; the
scene of the accident is inspected, and a report printed, setting out
the cause, so far as can be ascertained.

Until the introduction of chlorate of potash about 1830, if even
reasonable care had been used the chances of spontaneous ignition were
very small, and it is reasonable to suppose that such accidents as did
take place were in the majority due to such incidents as the above.

After that date, however, it is not too much to say that quite as large
a proportion of accidents were due to the admixture of chlorate of
potash and sulphur.

We are, of course, now speaking of accidents during manufacture,
although to the same cause may be attributed many of the numerous cases
of bursting mortars during displays which were so frequent until the
prohibition of this mixture in 1894 by Order in Council 15.

Dr. Browne, of Hull, a consulting chemist, published in 1884 a book
entitled, “Firework Accidents, their cause and prevention,” in which he
divides accidents into three classes: mechanical, chemical (spontaneous
combustion), and mechano-chemical.

Such a classification seems to the writer misleading, as all accidents
must of necessity be chemical; that is to say, for combustion chemical
action must take place; and with the exception of cases where ignition
has taken place quite spontaneously, that is where the composition
has ignited when lying perfectly undisturbed, all must be considered
mechanical.

Almost any composition used in pyrotechny, however stable, can
be ignited by a violent blow between two hard surfaces, but some
compositions are so unstable as to be ignited by very slight friction.

It is therefore a question of degree, or whether the mechanical factor
is most to blame or the chemical. A better classification would be:

   I. Ignition caused by violence, friction or heat.

  II. Accidents caused by the state, condition or quality of
      the composition or ingredients.

If the accident be included in the class which gives the fundamental
cause of the accident, it will be found that the greatest number fall
in Class II, even though they may at first glance appear to belong to
the first class.

Class I includes accidents caused by the accidental presence of fire
and accidents caused by necessarily more or less violent action in
manufacture, that is to say, in charging.

Ignition during charging may be caused in two ways, either by a blow
on composition between the charging tool or drift and the spindle or
other hard surface, or by heat generated by repeated blows on the
consolidated composition.

In this class also should be put accidents, of which there are many,
caused by playing or scuffing by the workpeople, the absence of safety
overshoes, the presence of grit or iron or steel implements, in fact
those caused by misconduct or negligence on the part of the workers,
also the rare occasions where lightning has been the cause.

Accidents caused by slight friction have to a great extent ceased to
exist owing to the elimination of chlorate and sulphur compositions.
Where accidents arise owing to instability of the composition, they
most frequently at the present time fall within Class II, as the
instability of the composition is generally due to the presence of some
impurity in one or more of the ingredients.

Another source of accident of this class is the use of violence in
emergency with a composition which, although not sufficiently stable
for heavy charging, is quite safe for careful manipulation; as for
instance, where force is exerted to clear a funnel which has become
blocked with composition, or some similar action.

As regards the part played by heat in accidents of this class, a
study of the records clearly indicates how great is the influence of
weather. By far the greatest number of accidents take place in the
summer months; hot weather and a heavy atmosphere are the most likely
conditions to produce trouble for the pyrotechnist, although whether
the primary cause is heat or owing to an electrical condition of the
atmosphere it is difficult to say, probably it is the two conditions in
conjunction. Sulphur and shellac, two very important ingredients in the
art, are both capable of holding an electric charge, and it seems not
unlikely that they may be so charged in an electric atmosphere during
the process of mixing.

Accidents in Class II are generally less easily explained than those
in the former class and have occurred in many forms. As has been said,
during the period (about sixty-five years) from the introduction of
chlorate of potash to the Order in Council forbidding its use with
sulphur, numerous accidents occurred; spontaneous ignition, both whilst
drying during manufacture and even during mixing, ignition from very
slight friction, and for a time a frequent occurrence the detonation
of the contents of shell by the lifting charge. During the period
of seventeen years between the date of the Explosives Act and the
prohibition of chlorate sulphur mixture, twenty-eight accidents are
recorded, resulting in eleven deaths attributable to the use of such
mixtures.

The instability of chlorate sulphur compositions, however, does not
appear to be so much due to the presence of these two chemicals
themselves, but rather to the presence of impurity in conjunction with
them.

Commercial sulphur often contains free sulphurous acid, which acting
upon the chlorate produces chlorine tetroxide, which rapidly decomposes
and ignites the mass of the composition.

Other acids which produce decomposition of the chlorate are equally
likely to produce ignition. Of such cases, examples may be mentioned
of acid being present in the paste used for case and box-making, also
in gumwater which has been kept some time before using, and in starch
paste similarly treated. Spontaneous ignition has also been caused by
the contact of oil with finely divided carbon such as lampblack or
finely divided metals, such as magnesium and aluminium, which are so
largely used at the present time.

Another case of this nature is the heating up of cases after charging
with gerb composition, two of the ingredients of which are sulphur
and iron borings, this heating sometimes being sufficient to cause
combustion. The cause of this phenomenon is the combination of the iron
with sulphur to form sulphide of iron, this action being accompanied by
heat. In fact, it is the same as that producing the experiment known
as Lemery’s volcano. As far as the knowledge of the writer extends,
however, no occurrence of ignition has been definitely traced to this
phenomenon, although it seems highly probable that even if ignition of
the actual composition has not taken place, cases have occurred where
more sensitive compositions have been fired by heat so generated where
fireworks have been stored together.

The annual reports of H.M. Inspectors of Explosives published since
1876 form an interesting and instructive summary of accidents in
explosive trades, an examination of which throws considerable light on
our subject.

One is struck by the frequency with which explosions occur as a result
of ignorance, generally on the part of amateur firework makers. In many
cases, as where children are concerned, this ignorance is natural, but
the want of knowledge and even reasonable care displayed by individuals
whose occupation suggests at least some knowledge of the risk is indeed
often extraordinary.

Such a case occurred in 1884 in Devonshire, when a local chemist who
was illegally manufacturing coloured fire, instructed an assistant to
grind in an iron mortar a mixture containing chlorate of potash and
sulphur. The lad was killed in the resulting explosion.

Even more remarkable was an explosion which took place in a railway
carriage in 1893. This was due to the spontaneous ignition of a
quantity of chlorate and sulphur coloured fire, which was being carried
in an ordinary handbag by a gentleman whose occupation in life was that
of professor of chemistry.

An accident presenting considerable interest took place in 1885 at
Mitcham. The cause of this occurrence was quite simple. A man was
fixing the curved stick which forms the pivot upon which a tourbillion
rotates to one of those fireworks. The wire nail used for the purpose
penetrated the composition and fired it. The remaining goods in the
shed were ignited, and communicated to the neighbouring buildings, one
of which was a magazine containing 3,000 lbs. of partially manufactured
fireworks, including a number of rockets. These being without sticks
and becoming ignited flew in all directions, setting fire to other
buildings. The result was that ten buildings and an air drying rack
were totally destroyed, and three buildings and three racks partially
so.

This would seem a very serious matter as far as monetary damage is
concerned, but as regards the chief consideration in accidents of this
kind, that is to say damage to human life and limb, the result was
almost negligible; two persons were slightly injured.

This accident, which was the most extensive in any firework factory
since the Explosives Act came into operation, afforded striking proof
of the efficiency of the precautions instituted under that Act.

It is indeed extraordinary that in an explosive factory of considerable
size, employing many workpeople, during working hours it should be
possible to destroy more or less completely seventeen buildings and
only slightly injure two persons.

It may be contended that the number of buildings damaged was very high,
but it must be remembered that rockets without sticks take a most
erratic course in their flight, rendering the effective screening of
other buildings most difficult, if not impossible.

However, there is evidence that many rockets were stopped by the
screens, and that without their interposition the number of buildings
destroyed might have been many times greater.

The other Explosives Act requirements of which the efficiency was
demonstrated by this accident, are the dividing of sheds into
compartments with a limited number of workpeople in each, easy means of
escape from working buildings, and the value of uninflammable clothing.

It was also shown that a large quantity of fireworks might be burnt
in mass without causing a veritable explosion; as in the case of the
magazine containing 3,000 lbs.

Contrasting with this occurrence are the reports of accidents in
firework factories both on the Continent and in America.

The same year, at Civita Vecchia, ten persons were killed and twice
that number injured in one accident at a firework factory.

Four years later, in Paris, seven girls were killed out of the eighteen
employed in one compartment. The material being used was red phosphorus
and chlorate. In 1882 fourteen persons were killed and no fewer than
seventy injured at Chester, Pennsylvania.

From 1891 to 1894 eight accidents in the United States are reported,
resulting in a total of twenty-three deaths and injury to more than
fifty persons. In 1894, at New Haven, Con., damage to the extent of
125,000 dollars was done, and at Dallas a considerable part of the city
was destroyed.

These are, of course, not a complete list, but only such cases as are
brought to the notice of the English Home Office, but the extent of
these clearly illustrates the value of the restrictions in force in
this country.

During the same years the total of firework factory accidents in this
country was thirteen, in which three persons lost their lives, and in
no case was more than one person killed in any one accident. Indeed, in
one instance only since 1875 has the number of deaths resulting from
any accident exceeded two—on that occasion four deaths resulted.

An interesting type of accident, examples of which have taken place on
several occasions, is that in which two compositions, one containing
sulphur and the other chlorate of potash, are placed in contact in the
paper case of a firework, and produce spontaneous combustion.

In one case a lance containing white and green composition burst into
flame on the work bench. This provided an explanation to an explosion
at the same factory which had taken place ten days before in a magazine
containing between 6,000 and 7,000 lbs. of display fireworks.

An occurrence of a similar nature was observed at Brighton in 1903,
when some changing coloured lights which had been removed from a
building where a fire had taken place (the fireworks not being involved
in any way) ignited some days afterwards.

It is thought that the lights may have been wetted during the fire,
and upon drying out some days later the different compositions in
contact in the case or cases set up chemical action, which resulted
in spontaneous ignition. It was found on examination that a blue
containing sulphur was in contact with a green containing chlorate. It
may be noted here that mixtures which are damped during manufacture are
more liable to spontaneous ignition than those manipulated in a dry
state.

Many accidents and explosions are left unexplained, either because the
evidence is destroyed by the resulting fire or by the death of the
witness or witnesses, or because of the difficulty often experienced
in getting the workpeople to give a full and faithful account of what
occurred, fearing to cause trouble for themselves or others concerned.

There can be no doubt that the cause is frequently carelessness or
mistakes on the part of workers. In a large number of cases, however,
this explanation gives no help and the cause remains obscure. One such
may be mentioned:

In 1902 an explosion occurred in a store for non-explosive ingredients,
in which were kept the chemicals used in a firework factory. In the
building at the time was a workman who appears to have been engaged in
sifting chlorate of potash, and the technical manager of the factory
who seems to have been weighing out ingredients. There is no doubt that
he was a man of very considerable experience, and from his responsible
position unlikely either to take risks or be guilty of carelessness.

An explosion occurred in the building, killing both occupants, and of
so violent a nature as to sever the foot of the manager and to project
one of the sheets of corrugated iron with which the roof was covered a
distance of thirty yards.

No explanation of this occurrence was arrived at other than that
in some way some of the chemicals must have become mixed to form a
sensitive and violent explosive; so much is obvious, but how the
chemicals became so mixed remains a mystery, as no mixing was actually
done in the building. The ignition of such a mixture is less obscure
as magazine boots were not necessary in the building owing to the
non-hazardous nature of the work carried on there, and sufficient
friction would be produced to fire even a fairly sensitive mixture
between a nailed boot sole and a wood floor.

An occurrence of considerable interest in this direction took place in
a warehouse at Manchester in 1908. In the building were stored several
tons of chemicals, among which were twelve tons of chlorate of potash
and thirty-two of chlorate of soda.

A workman stepping down from a barrel struck fire, and saw a flame,
which he tried to extinguish by rubbing with his foot. This, however,
had the opposite effect. He then tried a bucket of water, which failed
to put it out; he left the building and heard an explosion, followed
by a second and a third, all apparently of a violent nature, all three
being heard nearly ten miles away, and glass broken throughout a
considerable area round the warehouse.

The cause appears to have been as follows: During the conveyance of the
chlorate into the building leakings took place, and a certain quantity
remained on the floor, this mixing with dust and other organic matter
would prove a highly sensitive composition. This was ignited by the
man’s foot and rapidly spread, probably a deposit which had accumulated
under the floor became involved. The woodwork of the building and the
wooden barrels then became ignited. The rapid decomposition of the
chlorate caused by the heat liberated large quantities of free oxygen,
which united with carbon in the smoke to form gas, which exploded upon
reaching the correct proportion for so doing.

The writer has chiefly confined himself to accidents in firework
factories; those occurring during the illegal manufacture of fireworks
in premises unlicensed for the purpose present no further interest, and
are generally caused by ignorance on the part of the participant of the
often extremely dangerous nature of the material he is handling. To
take an example:

Two boys were engaged in grinding in a mortar a “small quantity” of
chlorate of potash and sugar. An explosion resulted which blew out
the entire window frames of the room, destroyed the partition between
the room and the passage, considerably damaged the other wall, and
projected the pestle into the ceiling, where it remained embedded.

Accidents at displays are now happily rare; the most fruitful cause of
such happenings was the detonation of shell in the mortar, that is,
the detonation of the contents or “garniture” by the explosion of the
propellant charge.

The elimination of chlorate-sulphur composition has reduced the chances
of this to a minimum, and the compulsory burying of mortars up to
the muzzle has practically eliminated the danger to either firers or
spectators.

Apart from slight injuries caused by falling rocket sticks and mishaps
of a similar nature, accidents to the public at firework displays are
things of the past.




                                PART II

[Illustration: Types of Modern Fireworks.]




                               CHAPTER I

                     SIMPLE FIREWORKS—ROCKET CLASS


In the preceding chapters we have been dealing with displays of
fireworks, that is to say; fireworks in the mass. We will now turn our
attention to the firework units composing those displays, and endeavour
to trace their gradual evolution from the crude originals.

Fireworks may be divided into two classes, simple and compound.
The first of these include fireworks which are a complete item in
themselves, as the rocket, shell, or Roman candle; also the units
which, fitted on a framework, go to compose the set pieces and devices
of a display, and the small shop goods not used in displays. We will
consider this class first.

The two oldest forms of fireworks known are undoubtedly the cracker
and the rocket. As we have already noted, both of these—or at least
primitive forms—are mentioned by Marcus Graecus, Albertus, and Roger
Bacon. The description by the former is sufficiently clear to leave
no doubt in our minds that he is describing a rocket; although the
description of a cracker is not so explicit as to enable us to say
that he is actually describing a jumping cracker, yet his mention of
folding and tying would certainly give colour to that belief. In fact,
some writers have endeavoured to find a connection between the words
“Graecus” and “Cracker.”

Greene, in “Orlando Furioso” (1599), uses the words, “Yes, yes,
with squibs and crackers brauly.” John Bate, in his book previously
mentioned, under the somewhat misleading heading, “How to make
Crackers,” says: “It is well knowne that every boy can make these,
therefore I think it will be but labor lost, to bestow time to
describe their making.”

He also describes a kind of kite which he designates a “Fire Drake,”
to the tail of which he fastens “divers crackers” which are shown in
the illustration to be exactly like the jumping crackers of the present
day. Babington illustrates a cracker fixed to the top of a rocket.

Pepys makes the following entry in his diary for November 5th, 1661:
“Seeing the boys in the streets flying their crackers.”

The only practical difference between the cracker of 1635 and that
of to-day is in the difference of methods of manufacture, the early
practice being to fold the gunpowder in the paper, the modern, to
roll a paper case and fill the powder in through a funnel, afterwards
flattening it through a roller mill.

[Illustration: Cracker Making]

Curiously enough, although the cracker has been in use for centuries in
England, there appears to be no early reference to it on the Continent,
the word “petard” meaning a cracker in French, but more often being
applied to a firework with a single report, such as a maroon or cannon.
The _Dictionnaire National_ of 1852, however, describes the true
cracker as one of the meanings of “petard.”

The rocket is equal to the cracker in its claim to antiquity, and it is
extraordinary that these two fireworks should have changed so little in
form and composition.

John Babington gives illustrations of rocket-charging tools and
describes the manufacture of rockets, which are approximately those of
the present day. It is only in the proportion of the ingredients that
there is any considerable alteration.

The word “rocket” appears to be Italian in origin, and to be based on
the similarity in appearance of a rocket on its stick to the round
piece of wood used in the Middle Ages to cover the point of a lance in
mimic combat, and known as a “rockette,” from “rocca,” the Italian
word for a bobbin, a diminutive of distaff.

As a rocket is the most important unit in the art of pyrotechny, a
description of its manufacture will assist in the consideration of a
large number of other fireworks which are either modifications of or
based upon the underlying principles of the rocket, as well as the
several principles governing all fireworks.

The ingredients of rocket composition are those of gunpowder in
approximately similar proportions, but the resultant composition is not
gunpowder, the reason being that the ingredients are less intimately
mixed, with the result that the combustion is spread over a longer
interval of time. Instead of the whole mass deflagrating instantly,
only the exposed surface is consumed. It is the recoil produced by
the rush of gases, and partially consumed matter, from the violently
burning composition which projects the rocket forward. The obvious form
for the case containing the composition is cylindrical, both on account
of ease of construction and of charging. In order to get the greatest
possible reaction from the burning composition, the case of the rocket
is constricted or choked, so that the fire may issue as it were in the
form of a jet. This choke has one obvious disadvantage, it reduces the
surface of composition to the area of the opening, thus restricting
the initial burning surface at the time when the maximum of effort is
required to force the rocket into motion. This defect is overcome by
having a tapering hole up almost the entire length of the composition,
thus giving a large burning surface with a consequent discharge of gas
through a small orifice and a resultant powerful jet of fire and gas.

The rocket case is of stout paper rolled on a former consolidated by
rolling under a board. The choke is formed by inserting into the bore
of the rocket two wooden tools with rounded ends, the shorter tool
having a peg projecting which is equal in diameter to the bore of the
choke. The tools are of such length that when they are inserted the peg
takes up the position where the choke is to be formed. The case is then
constricted at this point by a strong pressure with a stout cord wound
round the case and soaped to allow it to slip round easily.

The case is then dried and charged by placing on a “spindle,” which
is a strong gun-metal base with a nipple fitting into the vent of
the rocket and having a tapering spindle which fits tightly in the
choke and projects up into the bore of the rocket. The composition
is poured in in small quantities measured in a scoop, each scoopful
being consolidated by blows with a wooden mallet or a wooden “drift”
hollowed to take the spindle. Before the first scoop of composition is
introduced, the rocket is “set down,” that is, several blows are given
on the drift to consolidate the paper at the choke and give it accurate
shape. Next, a scoop of ground dry clay is poured in and charged
firm as a protection to the paper of the choke. The charging is then
proceeded with as detailed above. Varying drifts are used in order that
the hole may approximately correspond with the diameter of the tapering
spindle as the composition rises in the case.

A short portion of the case above the spindle is charged solid; this is
referred to as the “heading,” and is usually about one and a half times
the bore in depth.

Large rockets are charged in a mould which fits tightly round the
outside of the case and prevents the case being split under the
pressure of the blows whilst being charged.

[Illustration: Rocket Manufacture, from Frézier’s “Feu d’Artifice,”
  1747.]

In early times these moulds were used for all sizes and were of cast
metal, and it is from them that the classification of the sizes is
derived. Rockets are designated by the weight of a ball of lead which
fits the bore of the corresponding mould. Thus we have rockets
varying in size from ½ oz. to 6 lbs. and over, war rockets being made
up to 9 and 24 lbs., but their use is now almost extinct.

This classification, although it serves its purpose well enough, is
somewhat misleading, as the thickness of the case varies in practice,
at any rate under modern conditions. In the seventeenth and eighteenth
centuries pyrotechnists seem to have had a standard proportion between
the case and bore, _i.e._, the thickness of the case was one-quarter
the internal diameter of the rocket.

In modern commercial practice a rocket—say for example of 1 lb.—is a
rocket rolled on a former whose diameter is that of the bore of a 1 lb.
rocket of standard thickness, but whose outside diameter is governed by
the strength of the paper employed in the case.

Several writers on pyrotechny, one Frézier writing in 1747 in
particular, have endeavoured to supersede this classification
of rockets by replacing it with a series of internal diameter
measurements, so far without success. It is hard to supersede the
traditions of centuries on a plea of mere rationalism.

Rocket compositions, although containing the same ingredients, namely,
saltpetre, sulphur, and charcoal, have them in differing proportions.
Broadly speaking, the larger the rocket the greater the proportion of
charcoal and sulphur, the variations in proportion being considerable,
from the half-ounce rocket mixing of 13 saltpetre, 2 sulphur, and 5
charcoal to the 9 lb. and 24 lb. war rocket, with 13 saltpetre, 3
sulphur, and 4 charcoal approximately, and even higher proportions
of the second and third ingredients for special purposes. A larger
proportion of charcoal gives a larger tail—a desirable feature in
display and signal rockets. Some compositions have a proportion of
mealed gunpowder to produce fiercer burning.

Early makers appear to have used mealed gunpowder and added charcoal
and other ingredients to, as it were, dilute the powder and render
the deflagration less fierce. Babington (1635) adds charcoal in the
following proportion:

   1 oz.—4 oz. rockets, 1 lb. of mealed powder to 2  oz. charcoal
   4 oz.—10 oz.  „      1 lb.      „       „      2½ oz.    „
  10 oz.—1 lb.   „      1 lb.      „       „      3  oz.    „

John Bate’s compositions are rather erratically arranged; in some cases
he adds the saltpetre, charcoal, and sulphur, and a further addition is
“yron scales,” presumably to increase the effect of the tail, for which
purpose later pyrotechnists used iron filings.

The rocket having been charged to the top of the heading, clay is
charged in, forming a diaphragm above it. Earlier practice was to turn
down the top edge of the case on the heading composition to form a
diaphragm.

The best-known form of rocket is the sky rocket, which is fitted with
a stick held in position by having a dowelled end introduced into a
rolled paper or metal tube secured to the side of the rocket. The
object of the stick is to direct the flight of the rocket, and further
serves to hold it in position for firing, being passed through two
rings at a suitable distance one above the other on a stake, through
which it slides easily.

Sky rockets are fitted with a “cap” containing the “garniture” of
the rocket, which may take the form of “stars” or other pyrotechnic
effects, or a gun-cotton wad, or similar explosive to make a sound
signal, or small cases charged with picrate of potash, producing the
well-known “whistling rocket” effect.

The “cap” is either cylindrical or in the form of a truncated cone,
with a conical or other top. The cap is burst open and the contents
ignited by an opening charge of powder lighted through a hole bored in
the clay diaphragm above the heading, so that when the heading is burnt
through the fire may be communicated to the opening charge.

From earliest times the rocket has been the chief item in recreative
fireworks; either the sky rocket as we know it to-day or its many
modifications and derivatives was the chief constituent of the early
displays.

During the sixteenth and seventeenth centuries a display would contain
the following items—dragons or similar figures issuing from the scenic
castle provided for the display; these would be moved by line rockets.
A line rocket has no cap or garniture, the socket usually provided to
hold the stick being lengthened, and of sufficient diameter to allow it
to slide along a tightly stretched cord passed through it. Pieces of
a similar nature to the modern fountain and gerb would be represented
by “ground rockets.” This is a rocket less fiercely burning, charged
solid, fixed to a support so that it remains stationary whilst burning,
the fire being thrown out in a jet. Rockets would also be used to turn
such primitive wheels as were exhibited, and to actuate mechanical
scenic devices, which are in effect the “turning cases” of the present
day. Serpents of fiz-gigs were much used, both as a garniture for
rockets, and to give animation to wheels and similar pieces. These were
made on the rocket principle, similar to the squib, but slightly more
elaborate. A choke was formed between the composition and the “bounce”
or powder giving the report.

To-day the ground rocket has developed into the gerb or Chinese tree,
fountains of various kinds, the flower pot—of the larger kinds; and
among the smaller varieties, the squib with its variations, such as
Black Jack and Blue Devil, and the golden rain with its variations.

The modern, or rather more recent, method of heading the rocket with
a clay diaphragm evidently suggested that the choking of the case
might be dispensed with where the composition was less fierce, the
necessary reduction of the orifice being produced by a clay diaphragm
with a central hole of sufficient size. This method is followed with
the gerb, fountains, and flower pot, and in the firework known to
pyrotechnists as “fixt”; this unit is largely used in display work to
form the fringe frame or lattice effect of a set piece. “Fixt” are made
in 1 oz. and 2 oz. sizes, and contain a composition of approximately
one part of steel filings to four of mealed gunpowder and finish with a
bounce. The origin of the name is uncertain: it may refer to their use
on fixed pieces in contradistinction to one revolving, or—as is most
probable—was first used to distinguish between a fixed and a moving
rocket.

The time of the introduction of the clay choke is uncertain. Jones,
writing in 1765, although using clay in the heading of rockets, still
choked all cases, but Mortimer (1824) uses it, although Ruggieri
(1821), whilst doing the same, appears to think choking preferable.

The former gives instructions for charging the clay solid and boring
the central hole; Ruggieri, however, uses a nipple like a much
shortened rocket spindle, in which he agrees with the modern practice.
This method is also utilised at the present time for small-sized
rockets.

Of the fireworks of the fountain class, probably the first to develop
from the crude rocket form were the gerb and flower pot. The gerb, or
Chinese tree, contains a composition of saltpetre, sulphur, charcoal
and iron borings, with the addition—if more force is required, as
for instance to turn a device—of mealed gunpowder. Early makers used
mealed powder alone and “iron sand,” or cast-iron reduced to powder
by hammering. This composition is known as Chinese fire, and, as its
name implies, was introduced into Europe from the East. An interesting
article appeared in the “Universal Magazine” of 1764, written by
a Jesuit missionary on the subject of Chinese fireworks. In it he
describes the making of iron sand as follows:

  “Old broken or useless pots serve generally for making this sand;
  they are broken into pieces of the breadth of the hand, after
  which, being made red-hot in the fire of a forge, they are thrown
  in that condition into a trough filled with fresh water, where they
  are left to cool. Thus calcined, the rust falls off in scales, and
  they are easily reduced into sand, being first broken into parcels
  of a finger’s breadth. The anvil and hammer used for this purpose
  must be also of cast-iron, because steel flats the grains of sand.
  It is necessary that the angles of those grains should be sharp, as
  it is the angles that form the flowers.”

The word “gerb” is derived from the French word meaning a sheaf of
corn, and was first applied to water fountains.

The flower pot is charged with a composition formerly known as
“spur-fire,” from the resemblance in form of its coruscations to the
rowel of a spur. The effect produced is one of the most effective
when successful, but has the disadvantage for display work that the
effect is only appreciated at close quarters. The ingredients used are
lampblack, sulphur, red arsenic, saltpetre, with sometimes the addition
of charcoal and mealed gunpowder.

Of the smaller works of this division the squib and golden rain are
too well known to need description. The squib and its variations have
a choked case; the golden rain and similar works are left with an open
bore.

Squibs are generally filled with a composition of sulphur, saltpetre
and charcoal, sometimes steel filings, with a bounce of fine-grain
powder.

A curious firework, now almost obsolete, for which it is difficult to
find a class, is the five-pointed star. This work consisted of a case
having a diaphragm of plaster of paris or clay above the filling, below
which five holes are bored equidistant and at right angles to the axis.
The case is fired in the unusual position of horizontal with the end
towards the spectator, the fire playing all round the case, forming a
star. The composition used was mealed powder, sulphur, saltpetre, and
sulphuret of antimony. Ruggieri mentions this firework under the name
“Etoile fixé,” and it is mentioned by Jones, writing in 1765, but not
by Frézier.

It is hard to believe that this unit was successful, so many factors
militating against success, which depends upon the exactly similar
jet from each of the five holes. But it is possible that in large
geometrical pieces it was at least of use to give an additional effect
in what, owing to the lack of variety of the fireworks of the time,
must have been rather a monotonous repetition of a few effects. It
also would enable small blank spaces to be filled in on set pieces. In
a sun or star of the ordinary type, that is of radiating cases, the
commencement of the jets must be as far apart as the length of two of
the cases, which length is governed by the required time of burning.
This leaves a blank centre; the five-pointed star, however, if working
correctly, has the jets radiating from a point.

Many of the earlier writers classified fireworks under the
heads:—Fireworks for the ground, for the air, and for the water. Those
falling in the latter division are only variations of those for the
ground, that is to say, a gerb, fountain or other firework is fitted
with a float, such as a block of wood, and functions floating on
the surface of the water, the effect being greatly enhanced by the
reflection.

[Illustration: From “The Universal Magazine,” 1764.]

It is not proposed to deal separately in this work with aquatic
fireworks unless they have some essential difference from their
parallel type for land display.

One unit, of the rocket class, which is so distinct is the “skimmer.”
This is in effect a stickless rocket with the cap (which is empty)
fastened at an angle to the line of the main case. When fired the
skimmer, as its name implies, skims over the surface of the water, with
occasional dives under the surface in an erratic course. It requires
for its safe display a considerable area of water. These are known by
French pyrotechnists as “genouillères,” from their shape.

Ruggieri and Frézier describe what they call “plongeons.” These are
gerbs charged in the ordinary way, except that before each scoop of
composition a small quantity of mealed powder is added. This produces
a jerky burning, the recoil of each puff of powder driving the gerb
beneath the surface of the water; the jet of fire, of course, is
sufficient to prevent water entering the case while so submerged.
These, and other earlier writers, in their section devoted to aquatic
fireworks, give directions for firing ordinary land fireworks on the
water, which would almost appear to have been included with the idea
of filling space. One item which is generally included consists of
directions for firing rockets under water. Jones, under this heading,
gives the following directions:

                   “TO FIRE SKY ROCKETS UNDER WATER.

  “You must have stands made as usual, only the rails must be placed
  flat, instead of edgeways, and have holes in them for the rocket
  sticks to go through; for if they were hung upon hooks, the motion
  of the water would throw them off: the stands being made, if the
  pond is deep enough, sink them at the sides so deep that when the
  rockets are in their heads may just appear above the surface of the
  water; to the mouth of each rocket fix a leader which put through
  the hole with the stick; then a little above the water must be a
  board, supported by the stand, and placed along one side of the
  rockets; then the ends of the leaders are turned up through holes
  made in this board, exactly opposite the rockets. By this means
  you may fire them singly, or all at once. Rockets may be fired
  by this method, in the middle of a pond, by a Neptune, a swan, a
  water-wheel, or anything else you chuse.”

It will be seen that the rockets themselves are above the surface,
which seems more reasonable than the instructions of some writers,
who, to get the effect of a rocket rising from actually beneath the
surface, give themselves an infinite amount of trouble to render the
case and connections waterproof. The effect seen from a short distance
is identical.




                              CHAPTER II

                     SIMPLE FIREWORKS—SHELL CLASS


We now come to a distinct class of fireworks, those whose functioning
depends on the propulsion of gunpowder. The first and parent of this
class is the shell or bomb.

The original name of the shell was “air balloon,” which is now
obsolete. Some writers have been misled by its appearance in old
amusement announcements into thinking a balloon ascent was referred
to, or that a balloon carrying fireworks was to be exhibited, at dates
considerably before the invention of gas or hot-air balloons.

In this connection it is interesting to note that Ruggieri claims that
his father was the first to release a balloon carrying fireworks in
1786.

As we have seen, the military use of shell dates from at least as early
as the middle of the sixteenth century.

Both Babington and Bate, writing in 1635, give instructions for
making shell, and although the book of the former is more advanced in
this particular matter, he is, generally speaking, considerably more
primitive.

Babington describes a hollow sphere of canvas, a part of which is
filled with a slow-burning composition, the remainder being filled
with stars and grain powder, the canvas is pierced to expose the slow
composition. The shell is fired from a mortar having a touch-hole. The
following are Babington’s instructions in the matter:

  “Load your morter piece with one ounce of corne powder, putting
  after a wadd and tampion, and put on your ball with the vent
  towards the mouth of your piece: so elevating your piece to the
  zenith, you may proceed to the firing of it, which must be after
  this manner: provide two matches ready lighted, having one in each
  hand, and first fire your ball with one hand and presently give
  fire to your piece with the other, alwaies holding your head under
  the horizontall line of your piece, for fear the blast annoy you:
  this having done you shall see your ball mount very high with a
  fair taile of fire, and when at its highest, shall break forth into
  a goodly showre of starres.”

This somewhat unconvincing account gives one to wonder if the worthy
gunner had indeed fired a shell such as he describes, and if so,
whether he was not more than “annoyed” at the result. He gives the
lifting charge as exactly one ounce, but gives no indication of the
size of the shell or mortar. It seems probable that he had never seen a
shell of this nature, and was giving his idea of it without practical
experience; this is the more curious as, generally speaking, his
book is wonderfully advanced for the period, and indicates personal
experience of the matters under discussion.

John Bate, although less fluent, gives greater indication of practical
knowledge of the matter. His “balloone” is rather oblong in section,
and is made by rolling canvas on a former, using eight or nine turns.
The ends are choked in the same way as a rocket case, one end being
choked on to a “little cane rammed full of a slow composition.” The
shell is placed in the mortar with the fuse downwards, which is ignited
by the flash of the mortar charge. Bate takes the precaution of
having a time fuse at the touch-hole of the mortar, and concludes his
instructions for firing by saying, “and while that burneth, retreat out
of harms way.” Altogether a more practical and convincing description.

Frézier (1747) makes the following prefatory remarks to his chapter on
shells:

 “The name of ‘balon’ is given to a firework which is thrown into the
 air like artillery bombs for war, so that they are often given the
 same name as bomb.

 “The difference between this firework and a bomb is not only that
 the former is to amuse and that the latter to destroy, and that the
 one is made of iron, and the other of wood, linen, or cardboard, but
 principally because the latter is made to burst and throw out its
 garniture at the point of the highest elevation, while the war bombs
 do so at the moment of their fall to the earth, also the war bombs
 are thrown towards the horizon, while the firework bombs are thrown
 vertically or nearly so.

 “The fireworks differ also from the war bombs in shape, the former
 being not always spherical, as the latter are.

 “We must therefore understand by the name of shell a firework of which
 the effect and principal beauty is that while going up in the air it
 only shews a small stream of fire, which multiplies itself suddenly
 into a great number of others at the moment of its highest elevation,
 which causes a pleasant surprise.

 “As this firework does not lift itself, but is thrown by impulsion
 the same way as a bomb, it can, like the latter, only be fired from a
 mortar.”

He describes two shapes of shell, the spherical and cylindrical, with
a hemispherical end, which shape is more convenient where the contents
are long in form, as rockets, Roman candles, etc. He attributes the
introduction of this shape to Siemienowitz, who, he says, made the
cases of wood. He himself, however, adopts the modern method, as he
does with the fuse, which he calls the port-fire. The lifting charge,
however, is placed in the mortar separately from the shell and ignited
at a touch-hole, in which, as will be seen, he differs from modern
practice.

He gives a list of garnitures or fillings, which are interesting as
showing the practice of the day:

  “The first is the one which gives the effect of a waterfall or
  head of hair. This is made of thin narrow tubes, or if possible,
  of thin canes, cut to the length of the shell, and filled with a
  slow-burning composition made of three parts of priming powder, two
  of charcoal, and one of sulphur, damped with a little petroleum,
  and capped with a paste made of powder crushed in distilled water
  or spirit and afterwards dried. All these are put in the tube,
  around the one which is used for the passage of the port-fire.

  “When it is full the loaded port-fire is introduced, and pushed so
  far that it reaches the frame, and when it is touching the lid,
  this lid must be glued by the rough ends to that of the tube, and
  the shell is finished.

  “As it is rather heavy, it is advisable to adopt means for its
  resisting the shock of the lifting charge of powder which drives
  it out of the mortar, by strengthening it with a covering of linen
  strips, which should be stuck on to the shell by means of a paste,
  composed of two-thirds of flour paste, and one-third of glue.

  “Unless this is done it often happens that the shell bursts before
  it rises in the air.”

The second consists of serpents, the third of “saucissons volans,”
similar to the “fiz-gig” of Bate; the choke in the middle between the
composition and the bang being varied in position so as to produce a
succession of bangs. The vacant spaces left over in the shorter may be
filled with stars.

The fourth is of stars arranged in beds of grain powder; the
interstices being filled with a mixture of mealed powder and charcoal.
The fifth of “light balls,” and for the sixth he describes “the manner
of making figures and various shapes in fire appear in the air.”
These letters are made on a frame covered with composition, and are
consequently limited to a size to the internal diameter of the shell,
that is, less than eight inches. It seems improbable that they could
be distinguished satisfactorily at the height of a shell’s trajectory,
besides which the difficulties involved, as he himself explains, are
very great, which no doubt explains the fact that this idea is now
obsolete.

Under the heading “Double and Triple Balloons,” this writer describes
the method of placing shell of smaller size inside a larger. The
bursting of the first shell lights the short-time fuse of the contained
shell, which falls some distance and bursts. With the triple shell this
action is repeated.

Jones (1765) divides shell into four kinds, namely, “illuminated
balloons” filled with stars; “balloons of serpents,” “balloons of
reports, marrons and crackers,” and “compound balloons.” The last
description is misleading, as the balloon is not compound but the
contents are varied, as for example, the contents of one specified ten
crackers of six reports, twenty golden rains, sixteen two-ounce cases
charged half-inch with star composition and bounced, two ounces each
of brilliant, blue, coloured tailed, large string and rolled stars.
It is hard to believe that this writer had ever seen a shell fired
in this manner, the result would have been mere confusion. The star
compositions of that date were very rudimentary, the colours when seen
from the distance of a bursting shell were indistinguishable.

One interesting detail in Jones’s work is the classification of sizes.
The smallest shell mentioned by him is the “Coehorn Balloon”; he does
not give the size, but it is given in the “Military Encyclopedia” as
4⅔ inches. This corresponds to the 4½-inch of to-day. The name was
apparently derived from a Dutch military engineer of that name. The
next size is the royal 5½-inch, and above that 8-inch and 10-inch.

Ruggieri (1821) is the first writer on the subject to have the shell
and lifting charge in a unit as is the practice to-day, which indicates
constructionally a great advance over his predecessors, although the
fillings show little progress.

The modern shell is arranged with a “lighter” of quickmatch, long
enough to reach from the top of the shell when in position in the
mortar to a sufficient distance outside the mouth to enable it to be
ignited without danger. The lighter fires the time-fuse in the top of
the shell, and at the same time two pieces of quickmatch which run
round the shell in grooves worked in the paper shell case, and ignites
the lifting charge, which is contained in a flannel bag, or in the case
of small shell, a paper cone.

The lifting charge projects the shell into the air and the time fuse,
which is arranged to burn through at the top of the shell’s flight,
ignites the bursting charge which opens the shell and fires the
contents.

The modern varieties of shell are almost infinite. Colours have been
brought to a wonderful pitch of depth and brilliance, besides various
kinds of fire for stars, producing stars with tails of the same and
contrasting colours.

Another class of shell, which might be called the compound, consists of
shell filled with fireworks of other kinds—Roman candles, tourbillions,
wheel-turning cases, small shell, and what gives undoubtedly the most
dramatic aerial effect yet devised, with rockets. The “thunderbolt,” a
shell 16 inches in diameter, containing a hundred 4-ounce rockets, has
always been a popular feature of the Crystal Palace displays.

Another variation of the shell is the comet, which is in effect a small
shell (generally about three inches) with an exaggerated fuse of
brilliant fire, which leaves a heavy tail during the comet’s flight.
These are usually fired from either side of the firing-ground in rapid
succession, producing an aerial arch, and opening just after having
passed each other.

The aerial maroon consists of a maroon fitted with a lifting charge and
time fuse.




                              CHAPTER III

                      SIMPLE FIREWORKS—MINE CLASS


The next group of fireworks is what may be called the “Mine” class, and
has some of its members amongst the earliest firework units.

To-day a mine consists of a quantity of small effects such as stars,
crackers, squibs, etc., blown simultaneously from a case, or in display
work—from a mortar. In the latter event they are made up into bags with
the lifting charge below, and are known technically as “bags.”

The “Mine of Serpents” and “Jack-in-the-Box” as sold in the shops
consist of a rolled paper case which acts as the mortar, at the bottom
of which is a lifting charge. This case has a light strawboard cover
with a central hole, through which passes a case charged with a golden
fountain composition, the lower end of which is not—as is generally
the case—“clayed.” The space round the central case is filled in with
squibs or crackers. When lighted the fountain case functions in the
usual way, but when finished ignites the lifting charge, which lights
and blows up the contained fireworks.

A very early reference to the “Jack-in-the-Box” is by John Babington
(1635). In Chapter XXXVII he says: “Another which I call Jack in a
Box. The order of making this is after this manner: provide a box of
plate, of what largeness you please—then putting in a quantity of corn
powder or powder dust (in the bottom of the box) you shall fill it with
fisgigs or serpents, leaving a case in the middle for a cane to go
through to the bottom, which cane must be filled with a slow receipt,
in which you shall put a quantity of champhire but no oyles, in regard
of the narrow passage it has to burn without any other vent.” He then
describes fitting the pasteboard top and concludes: “and light your
cane, which will appear like a candle, and after a pretty distance of
time you shall heare a sudden noyse and see all those fisgigs flying
some one way, some another. This toy has given great content to the
spectators.”

Frézier calls mines “Pots à feu” or “d’aigrettes,” which, he says, were
three, four, or five inches in diameter, and twelve to eighteen inches
in length. When fired in batteries they were called “Pots de brins.”

The smaller kind were ignited at a vent formed by choking the case,
the vent—when the case was in position—pointing downward. The larger
sorts were lighted from above, and were practically the same as the
Jack-in-the-Box, with the difference that there was a case similar to a
shell fuse instead of the central Roman candle.

Jones’ description of “Pots d’aigrettes” and “Pots de brins” are
similar, only that he fires the former with a Roman candle in the
centre of the central mortar of a group with a lighter from it to each
of the others, so that at the finish of the Roman candle the mortars
are discharged simultaneously.

An elaboration of the “Jack” is the “Devil-among-the-Tailors,” which is
the same device surrounded by Roman candles.

The next fireworks in this class—the Roman candle—is one whose genesis
presents a most interesting study. From the evidence available there
seems no doubt that this firework, in spite of its name, originated in
this country.

The first mention of anything resembling it is found in Babington’s
book. He describes what he calls “a trunck of fire which shall cast
forth divers fire balls.” It is one of a class, apparently in favour at
this time, intended to be carried on a staff, and known collectively
as “fire lances” or “clubs” (the former name is not to be confused with
the lances used in set-piece work).

The particular one under consideration, although it is very large,
being four inches bore, and only emits two balls or stars, is
undoubtedly the prototype of the “Roman.”

Bate describes a somewhat similar lance with the difference that
“petards” or single crackers are substituted for stars.

This was in 1635. Over one hundred years later, Frézier describes
an almost exactly similar firework under the heading “Artifices
Portatifs,” which name he adopts instead of the old name “Lance à feu,”
in order to avoid confusion with the lance as known to-day, which was
then coming into use.

This is the only mention he makes of anything that can be considered
to even remotely resemble a Roman candle, and as he refers to several
other writers, a justifiable inference seems to be that neither he or
they had any knowledge of such a firework. Had he known of it, such is
its popularity he would certainly have mentioned it.

Eighteen years later Jones describes exactly the Roman candle as made
to-day, to which he gives the name “Fire Pump.”

“Pumps” and “Pumps with Starrs” occur in the description subjoined to
engravings depicting English peace displays in 1697 and 1713; there
can be no doubt that the reference is to Roman candles or the earlier
development of them.

When, however, the elder Ruggieri came over to this country in 1749 to
conduct the Aix-la-Chapelle peace display in Green Park, in conjunction
with Sarti, no firework of this nature appears in the programme of the
display.

Here we have two pyrotechnists who can be considered to represent
the best skill of France and Italy; in fact, it was Ruggieri whose
arrival in France from Italy in or about 1735 marked the great advance
in pyrotechny in the former country. Yet the “Pump” does not appear in
this great display planned and executed by them, although for years it
had been a popular item in displays in this country. The obvious reason
for this omission is that they did not know of it.

In the early part of the nineteenth century the name “Roman candle”
comes into use both here and in France. The “English Encyclopædia”
of 1802 still uses the expression “Fire Pump,” but this is probably
because their article is copied almost verbatim from Jones’ book. The
name Roman candle, however, appears in an advertisement of a display
at Ipswich by William Brock in 1818, and Ruggieri the younger uses the
words “chandelle romaine” in his book of 1805.

How this firework received the name Roman is obscure; it may have been
affixed by one of the many Italian pyrotechnists working here, or it
may have had political or religious significance.

A firework functioning in the same way as a Roman candle is the Italian
streamer, which has stars of a composition containing lampblack, which
burn with a gold fire and leave a tail in their flight.

The Roman candle of the present day is made with an almost endless
variety of stars, but those in use when the name was first introduced
were of very simple character. Coloured stars, as accepted to-day, were
not introduced until about the thirtieth year of the last century.

The compositions given by Jones and Ruggieri would produce
approximately the same effect as the Italian streamer star of to-day,
but with little or no tail.

Lampblack compositions appear to have been introduced into Europe from
the East, and there seems to be no reason why Italy should have had
them before this country, or that the introduction of lampblack into
Roman candle star composition should be credited to Italy.

It seems more probable that the name Italian streamer was attached to
that firework in this country to distinguish it from the Roman candle
with tailless stars, and under the mistaken idea that the “Roman” was
a foreign importation, or that it would be more acceptable if labelled
with a foreign name.

As we have said, the modern Roman candle is made with stars of very
many varieties, but whatever kind of star may be used, the method of
filling is the same.

The principle on which the Roman candle is constructed is as follows:
The case is charged with a series of repetitions of the following—Roman
candle fuse, “dark fire,” star, blowing charge. These are repeated as
many times as the case will hold, and function thus—the fuse burns with
a fountain effect, and upon being exhausted lights the “dark fire,”
which lights the star, flashes round it and fires the blowing charge
which propels the star from the case. The blowing charge also ignites
the next layer of fuse, and the effect is repeated.

In filling the case different sized scoops are used for the blowing
charge, which is of fine-grain powder, the smaller scoops being used
at the lower portion of the case. This is done so that the stars may
rise to approximately the same height; the charge at the bottom acting
through a greater distance, naturally acts more effectively and less is
required.

Earlier pyrotechnists, in addition, as a means of regulating the height
of the stars’ flight, made the stars of differing sizes; this under
modern manufacturing conditions would be impossible, and has been
abandoned.

Roman candle fuse is composed of sulphur, charcoal, saltpetre in the
proportion of 4, 8, 15. The “dark fire” is of mealed powder, with a
small admixture of charcoal.

[Illustration: An old Firework Bill.]

Another firework which is probably a development of the Roman candle is
the jewel fountain. This consists of a fountain mixture of saltpetre,
sulphur, and charcoal, to which is added granules of star composition,
which are thrown out by the force of the fire, giving a fountain effect
in which appear variously coloured points of fire.




                              CHAPTER IV

                SIMPLE FIREWORKS—SAXON & LANCE CLASSES


The fireworks which form a class by themselves are the Saxon or Chinese
flyer, and the tourbillion. Both of these consist of a single case made
to revolve in the plane of its axis by jets of fire projected through a
hole at right angles to the axis.

Saxons revolve about a nail driven through the case into a post or
other support; they are charged with a composition of mealed gunpowder,
saltpetre, and sulphur.

The case is charged thus: the lower end is firmly “clayed” and the
composition is charged up to a point about ⅝ inch below the centre,
clay is then charged for ¾ inch, and again composition to within a
short distance of the top, which is again firmly clayed. Two holes are
bored near each end on opposite sides of the case, and a third hole is
bored through the centre of the case at right angles to the other two
and of sufficient size to take the nail or spindle on which the case
revolves.

The two holes at the end may be connected with match to light
simultaneously, or the time of burning may be lengthened by leading the
second half from the lower end of the first lit. In the larger sizes,
and generally in display work, a small case charged with a colour
composition is attached to the side of the case, producing a ring of
colour inside the fire of the saxon.

A smaller and cheaper form of saxon is what is in effect half of that
described above, the nail being at one end and the propelling hole at
the other.

[Illustration: Rocket Charging.]

[Illustration: Filling Roman Candles.]

Formerly saxons for display work were made with a wooden centre, on
which the two halves, which were charged separately, were fitted, and
to which the colour case was secured by a nail.

The tourbillion is a development of the saxon; instead of the central
spindle a piece of curved wood is secured to the case, forming a pivot
on which to revolve when lying on a flat surface, and two additional
holes are bored on the under side of the case, so arranged as to light
when the case has sufficiently rapid revolution and project it into the
air.

Jones describes tourbillions as made to-day, also saxons under the
older name of Chinese flyer. In addition, he describes what he calls
“table rockets,” which resemble four double saxon cases fitted to a
centre, which has a projecting cone upon which the device revolves.

He says that “table rockets are designed merely to show the truth of
driving and the judgment of a fireworker, they having no other effect
when fired than spinning round in the same place where they begin till
they are burnt out, and showing nothing more than a horizontal circle
of fire,” but afterwards adds that “these rockets may be made to rise
like tourbillions by making the cases shorter and boring holes in the
under side of each case at equal distances; this being done they are
called ‘double tourbillions.’”

Frézier shows tourbillions as at present manufactured, which he calls
“tourbillion de feu” or “soleil montant,” but the nearest device he
shows to a saxon is similar to Jones’s table rocket, made to revolve on
a spindle, and having several holes bored down the side of each case,
presumably to produce more effect. These he designates “tourniquets” or
“soleils tournants.”

He also illustrates two ordinary rockets mounted on a centre similar to
that of a double saxon. This he calls “baton à feu,” and describes that
one case lights after the other is burnt out, and one gathers that the
device is intended to revolve but how it can be made to do this by fire
issuing radially is not apparent.

The word tourbillion is the French for a whirlwind and is applied by
Ruggieri to a compound firework, which will be considered later under
that head.

What we know as tourbillion he names “fusée de table” (a table rocket),
and adds that they are commonly called “artichauts.”

The success of all the above, in common with rockets, depends on
careful and experienced construction and strength of the case, and it
is indeed curious that Jones describes the rolling of the cases for
these fireworks without paste except on the edge of the paper. It seems
incredible that an experienced pyrotechnist should make such a mistake,
and one is almost inclined to agree with Kentish (1878), who says of
Jones’s book: “The greater portion of it is absurd and impracticable,
and shows it was written by a person who undertook to teach what he
had not learnt.” Nevertheless Jones’s book, as Kentish says, has been
copied by almost every book published since, just as his own matter
was largely pirated from previous works. In fact, for a century and a
half the plates illustrating pyrotechnic works were in a great degree
fac-similes of one another.

The catherine wheel, or, as it is sometimes called, the pin wheel, is
a rotating firework of simple, as distinct from compound construction,
and should therefore be included in this class.

It consists of a long, thin case of small diameter, charged with a
composition of sulphur, saltpetre, and mealed gunpowder. This case is
wound round a circular block of thin wood, with a hole in the centre
through which a pin or nail is passed, forming a pivot upon which the
wheel turns.

The case of the catherine wheel, unlike any firework we have considered
up to the present, burns down as the composition is consumed, and
for this reason it may be included equally well in another small
class of fireworks. This class includes the lance, the port-fire, the
starlights, feathers, and the colour cases used on wheels and saxons,
etc.

The lance is used in display work in greater numbers than any other
unit. Some idea of the quantity used may be gathered from the fact that
on one of the battle set pieces shown at the Crystal Palace as many as
thirty thousand lances are consumed in a single display.

Lances consist of thin paper cases about the diameter of a lead pencil,
filled with colour composition, and primed, to facilitate the lighting,
with mealed powder damped with water. This sets and further serves to
retain the contents of the lance, which are not compressed solid as are
fountains, rockets, etc.

The port-fire is used as a means of lighting the pieces, etc., of a
display, and in the last century for military purposes; its composition
consists of a mixture of saltpetre, sulphur, and mealed gunpowder. It
was formerly known as a blue candle.

The starlight and feathers, as are the squib, golden rain, etc., are of
the garden type, and are not used in display work, as although burning
with pretty effect, it is not distinguishable at any distance.

The feather and starlight compositions are similar to that of the
flower pot, but the cases are smaller, that of the feather being
catherine wheel pipe, but naturally not bent—the ends are closed by
“dubbing.” This is a method usually adopted for closing the ends of
“small goods.” The end of the case is introduced into an opening
formed by opposing V-shaped notches in an upper and lower series of
steel plates, the upper set being then forced down. The result is to
constrict the end of the case, which is then dipped in a mixture of
sealing-wax and glue.

Under the same head fall the Light group, which are wide and
comparatively thin cases filled with coloured or “bright” (as white
composition is known in the trade) composition. They are used either
for illuminating as Bengal lights, or for signalling purposes; if for
the latter, they are generally provided with a wooden handle and some
means of self-ignition.

The name Bengal light is probably based on the use of Bengal saltpetre,
and does not indicate their origin in that province.




                               CHAPTER V

                          COMPOUND FIREWORKS


Compound fireworks are those which are composed of a number of simple
fireworks or units fixed to a framework or other device so that they
produce a more elaborate effect than do single fireworks.

Probably the earliest form of compound firework was the wheel. After
the sky rocket had become an established fact, it was a small step to
tie rockets round a wheel, so that when fired they caused it to revolve.

Babington gives several devices based on the idea of imparting
movement to a wheel by rockets: he describes horizontal and vertical
wheels, which appear to be the same piece fired either horizontally or
vertically. In neither case is there any further effect than the fire
from the rockets tied to the periphery. His illustration shows no less
than sixteen rockets to fire singly in succession, which would, by
modern standards, make a rather lengthy and monotonous piece. He also
describes ground wheels, which consist of two wheels fitted to an axle
with a smaller wheel placed centrally between them. The centre wheel
has rocket cases fitted to it, causing the whole arrangement to revolve
and run along the ground. As an alternative he suggests substituting
cases secured to the axle without a central wheel, so arranged that one
being burnt out the second burns in the opposite direction and reverses
the direction of the wheels. The device is now quite obsolete.

One interesting point is the method of communicating fire from one case
to the next; quickmatch, as used to-day, had not then been invented.
His method was to fasten the cases head to tail a short distance apart
by wrapping and tying paper round in the form of a tube, the space so
formed containing some mealed powder.

He also describes what he calls fixed wheels, which are in effect the
fixed sun of to-day; that is, a framework with cases arranged radially
so that the fire is thrown out from the centre.

As variations of the above, he suggests various effects such as “a
fixed wheel which shall give divers reports,” “which shall cast forth
divers fisgigs, and likewise as many reports or breakers,” “which shall
cast forth many rockets into the ayre.” The latter is evidently the
prototype of a piece known later as the rocket wheel, popular for some
time, but little used at the present, the objection to it being that
there is no control over the direction in which the rockets fly from
it. The wheel revolves horizontally, and projects a series of rockets
into the air as it revolves.

During the following century, as compound fireworks developed in this
country, the Italian and French nomenclature was introduced, many of
which survive at the present time.

The pyrotechnists of the eighteenth century seem to have delighted in
inventing new terms, possibly with the idea of impressing the layman.
Frézier, writing over a hundred years later than Babington, records
very little advance in revolving fireworks, except in the matter of
names. He classifies all revolving pieces as girandoles. This word
appears in pyrotechny very frequently; curiously enough, nearly every
writer has attached a different meaning to it. Frézier explains that
the word is derived from girare—to revolve or gyrate, from the Greek.

Bate applied this meaning to it. He says, “How to make gironels or fire
wheeles.” He is, however, the only English writer to do so; others use
it to mean a flight of rockets, and occasionally for an elaborate fixed
piece of the fountain type.

Ruggieri and Sarti, both Italians, used it in the sense of a “flight”
of rockets in the programme of their Green Park display in 1749.
Ruggieri the younger, however, applies it to a specific kind of
revolving firework in his book, and introduces a new word—girande—to
which he applies the same meaning as the one generally accepted in this
country for girandole. The confusion of these two words, which have the
same derivation, may be the explanation of the duplication of meaning,
or it may lie in the fact that the name was also applied to the rocket
wheel previously mentioned, which both revolves and throws up rockets.

Frézier shows a wheel similar to that given by Babington, and
variations on the double saxon, a fixed sun also, as do most early
writers, double line rockets to run backwards and forwards and
variations. These latter, which appear to have been very popular at
this period, were known in France as “courantins.” Bate calls them
“swevels,” other early writers “runners on the line.”

The above-mentioned, together with some rather intricate but
impracticable appearing water devices, make up the compound fireworks
in Frézier’s book.

It seems, however, that he must have been behind his day in this
branch of the art, as the Aix-la-Chapelle peace display appears to
have included several elaborate pieces which, even allowing for the
usual exaggeration of the programme, must have required considerable
skill and knowledge in construction. These were mostly what were
called regulated or regulating pieces, generally described as of a
certain number of mutations. The pieces were, and are, although the
old descriptions are now dispensed with, so constructed that after
being lit they go through a series of alterations in form and movement
without further attention.

Some of those described in old works would seem to have required more
than a slight element of luck for their successful performance.

To-day it is often found more advantageous to make a second lighting in
cases where there is a danger of premature ignition, the effect to the
spectators being identical, and the successful functioning of the piece
secured. This does not apply to all pieces of this nature, as with
modern safety fuse the pyrotechnist has considerable advantage over the
earlier practitioners.

The modern spectator is only concerned with the effect produced, not
by the means adopted to produce it. It is difficult to-day to realise
the position occupied by the pyrotechnist of the eighteenth century. He
carried out his work personally, with of course trained assistants, and
occupied a position similar to the artist or sculptor. Each piece was
looked upon as a work of art, the personal effort of the pyrotechnic
artist. Ruggieri gives some idea of this in the following passage from
his book:

  “It was in the month of July, 1743, that my father and my uncles
  Ruggieri exhibited for the first time at the Theatre de la Comédie
  Italienne and before the King, the passage of fire from a moving to
  a fixed piece.

  “This ingenious contrivance at first astonished the scientists of
  the day, who said when it was explained to them that nothing could
  be more simple and that any one could have done it at once.”

He then explains the method of construction, which is to lead from the
back end of one of the turning cases through the hollow centre of the
axle to the lighter of the fixed piece situated behind it.

The development of fixed and mechanical pieces was made possible by the
introduction of quickmatch.

When this actually took place is uncertain. Frézier describes its
making similarly to that in use to-day, under the name of “étoupilles.”
Bate uses the word “stouple,” evidently a corruption of the French.
He gives no actual description of the making of this, but it appears
to be of “cotton weeke” dipped in “aqua vitæ wherein camphire hath
been dissolved.” This would produce only a slow-burning match unless
it was his intention to use it wet, in which case the burning of the
spirits of wine might quicken the effect. It would, however, be quite
out of the question to construct a piece of any elaboration with such
materials.

Quickmatch is manufactured to-day in the following manner. Cotton wick
is run through a pan containing a paste composed of gunpowder and
starch. It is wound on a frame six feet in length, dusted with mealed
powder and dried. When dry it is cut off the frame and threaded into
paper tubes or “pipes” of larger diameter, leaving an air space round
the match.

Before threading in the tubes it is known in the trade as “raw match,”
and is used for priming and similar uses, and in this state will only
burn quite slowly.

Quickmatch is used to connect the units of all pieces. Display cases
have a “cap” formed of a few turns of paper pasted on the case at the
lighting end. When a piece is fitted up the cases are tied to the
cleats provided to receive them on the framework; they are then “lead
up.” A length of quickmatch has a small piece cut out of the pipe to
allow the fire to flash through, it is then doubled at that point and
inserted in the cap, which is gathered in and tied round securely.
This is continued round the piece, each case having match entering and
leaving the cap, and in some cases a further length connecting one
series with another. This leading up of set pieces is work requiring
skill and knowledge which is only gained by experience. An amateur at
a first attempt might possibly be successful in lighting all the cases
on a piece, but he would be very unlikely to produce that instant and
symmetrical ignition which denotes the skilled pyrotechnist.

The smaller wheels have turning cases, that is, small rockets to give
them motion; these burn through very rapidly, and the continuation of
movement is provided for by capping the turning cases at either end and
leading them up vent to head in series; the motive power for the larger
display pieces is provided by gerbs, which, from the nature of their
fire, give more effect than would rocket cases, and have the further
advantage of burning longer.

It would not be possible in the present work to give a complete
catalogue of the varieties of pieces which have been produced, but the
list given by Ruggieri is typical of the whole, and includes many of
the smaller compound pieces in use to-day for shop and small display
work.

The larger display pieces are generally designed and redesigned season
by season by pyrotechnists, and are certainly being elaborated and
improved. They, however, fall generally into certain classes in the
same way as do those given by Ruggieri. His classification is as
follows:

  1. Stationary fireworks.
  2. Fireworks turning vertically.
  3. Mixed fireworks or fixed and turning.
  4. Fireworks turning horizontally or on a pivot.
  5. Built-up pieces turning on a pivot.
  6. Cut-out pieces and transparencies.

Of these, the last mentioned class are now obsolete: they consisted of
transparent and silhouette pictures or designs illuminated from behind.
He also includes both simple and compound fireworks in each class, but
as the former have already been dealt with they will be ignored here.

Class 1. (1) Glorys, fans and “pates d’oie” or goose foot, synonymous
with our expression crow’s foot.

Glory was a term used also in this country to signify fixed suns, as
mentioned above. Fans were cases five or more in number, arranged as
the name indicated, and pates d’oie, three similarly arranged.

(2) Mosaiques. These are geometrical designs formed by arranging gerbs
or fixt on framework, so that their fire forms a symmetrical pattern.
The effect is heightened by saxons in suitable positions, and in large
devices of this nature, small wheels, also formerly, the now obsolete
fixed or five-pointed star.

This type includes what are now called “lattice poles,” a series of
poles provided with cleats so that the fire of the cases crosses,
forming a lattice of sparks; also the more elaborate “carpet piece.”

(3) Feux croisés. These were similar in conception to the above, except
that the design is circular or based on the circle or wheel form; this
type is represented by the “fixt piece” of to-day, which is constructed
up to considerable dimensions, the large fixt piece at the Crystal
Palace often measuring sixty feet across the fire.

(4) Palm Trees. These consist of a framework intended to suggest the
form of a palm, provided with cleats to take the cases.

(5) Bouquets. These he describes also as a kind of tree different from
palm trees; his illustration shows that they were similar to the modern
lattice-pole with the difference that the cleats were not symmetrically
arranged.

To-day the word bouquet is applied to Roman candles arranged in what he
called “pates d’oie.”

(6) Cascade. This device needs no explanation. He says that Chinese
fire is the best composition for such a piece; this remained true up
to the introduction of the aluminium into pyrotechny, when the “weird
white waterfall” became a feature of the Crystal Palace displays, being
200 feet long and 90 feet high.

(7) Decorations in coloured fire. This heading introduces the lancework
set piece of to-day.

The development of this branch since 1865 has been very marked. As will
be seen from the description of the lancework pieces carried out at
the Crystal Palace, the subjects dealt with have been of extraordinary
variety. Up to the beginning of the nineteenth century pyrotechnists
had failed to realise the possibilities of lancework. This was
undoubtedly due in a great measure to the fewness of colours available.
Ruggieri appears to have used lancework to outline architectural
designs, evidently a survival of the temples or theatres of earlier
years. In his time, and even as late as the middle of the nineteenth
century, any subject of a pictorial nature was depicted by the use
of scenery or transparencies. Lancework was, as Ruggieri describes
it, merely “decorations in coloured fire.” The lances of his day were
considerably thicker than those at present in use, which are about the
diameter of a lead pencil. They were also spaced further apart and were
in some cases “bounced,” as are fixed cases of the present day.

The modern method of constructing a lancework set piece is as follows:
An outline drawing of the subject is made in which all unnecessary
lines are eliminated. This is ruled in square of such size that in the
proportion one square to a foot the completed piece will be of the size
required.

Frames are then laid out on the drawing-floor: these are of light
battens forming foot squares, and of a convenient size for handling,
generally ten feet by five feet.

[Illustration: Lattice Poles.]

[Illustration: Chromatrope

  (The outer fire forms the Guilloché of Ruggieri.)]

[Illustration: Lattice Diamond

  (The Feux Croisés of Ruggieri.)]

The drawing is then transferred to the floor with the assistance of the
squared lines, and the design followed by nailing on light wood strips
or thin rattan cane.

The lines thus indicated are then “pegged,” that is, pegs or small
wire nails pointed at either end, are driven in at intervals of about
four inches. The lances, whose construction has already been described
in Chapter IV, have their ends glued and are pushed on to the pegs so
that they stand vertically from the framework. The frames are then led
up with quickmatch, secured by pins driven into the priming. The match
is then pierced with a small awl above the priming, and secured and
protected by a strip of paper pasted over it and round the case of the
lance. The piece is then ready for hoisting into position and firing.

Formerly, and sometimes now on the Continent, the match was secured by
a wire passing through the case near the top, which was twisted over
the match.

Ruggieri, under this head, describes a method of illuminating by
impregnating wick similar to that used for matchmaking, with a mixture
of sulphur, antimony, and saltpetre. This was wired on to a metal
framework. He says it is better than lancework for outlining curves,
volutes, etc., as the line is continuous. This difficulty is disposed
of in modern English lancework by the closer spacing of lances on
curves rendered possible by the smaller lances now used.

He also remarks that this method was rarely used in his time and it is
now quite discontinued.

Another device of which he seems proud was a palm tree, the leaves
of which were of thin metal from which project spikes upon which was
hung cotton impregnated with a composition composed of “vert-de-gris,
vitriol blue and sel ammoniac” (copper acetate, copper sulphate and
ammonium chloride).

Immediately before firing the cotton was soaked with alcohol. Actually
this composition can hardly be considered pyrotechnic; what takes
place is that the alcohol burns, and the flame thus created is
coloured with the copper present in the salts. The whole arrangement
is too cumbersome and involved for modern use, but at the time of its
inception, when colour was practically unknown, no doubt it attracted
great admiration.




                              CHAPTER VI

                   COMPOUND FIREWORKS (_continued_)


Ruggieri’s next class (fireworks turning vertically) includes the
following:

1. Revolving Suns. These are merely vertical wheels; he appears to use
this term for the more ambitious pieces of this kind.

2. Vertical Wheels. He illustrates a vertical wheel exactly as made
to-day under that name. It has, however, been elaborated by the
addition of colour cases on the spokes and centre, as rosette and
rainbow wheels; also by the application of saxons to the spokes, as
saxon wheels.

He also shows the triangle wheel, consisting of three spokes with
grooved ends to receive the cases whose sides form the sides of an
equilateral triangle. This has been further developed into the double
triangle wheel, with two sets of spokes placed one set behind the
other. In all the wheels in this class the cases fire in succession,
not as in the case of the sun—simultaneously.

Windmills he illustrates as flat bars pivoted in the centre with three
cases at either end fired in succession. There also were three, four,
and up to eight-armed windmills of the same kind. The nearest device to
these of modern times is the chromatrope, the simplest form of which
has two bars with a gerb at either end so set as to revolve them in
opposite directions, the front one carrying two saxons. This piece,
which is of comparatively simple design, gives an extraordinarily fine
effect by the intersections of the various streams of fire.

The chromatrope has been developed and enlarged until for important
display work quite elaborate pieces are fired under this name.
Lancework of geometric form is used on the bars or spokes, and the
intersection of these, forming ever-changing geometrical designs, adds
greatly to the effect of the intersection of the fire.

This effect is the basis of the Guilloché, a somewhat elaborate piece
which falls in Ruggieri’s third class. It consisted of six wheels
placed one behind the other in pairs of graduated size; the two
smallest—which fired first—had six cases, the next eight, and the
largest forty-eight, and was twenty feet in diameter.

The next described is the Salamandre, a piece which, on a large scale,
is still occasionally fired at the Crystal Palace. It shows a snake
in pursuit of a butterfly which it seems to overtake but never quite
catches. The mechanism is an endless chain of wooden links running in
and out between eight sprocket wheels, arranged in octagon formation.
About half the length of the chain is made out and lanced to represent
the snake, and a lancework butterfly is situated in the centre of the
other half.

Ruggieri claims that his father fired this piece and the guilloché in
1739 at Versailles.

The other pieces mentioned in this section are too elaborate for
description in the space available, but are interesting as showing
the use of the helix and spiral as applied to wheels and cones, as
secondary elements of larger pieces.

The modern designer of pyrotechnic pieces has great advantage over the
earlier practitioners in that he has available an infinitely larger
range of colour and other composition. It is often possible to get a
much-enhanced result with less cases giving more or varied effects as
opposed to a larger number of cases of similar effects, which, in an
attempt to produce a lavish show of fire, end in confusion.

His fourth division begins with the “Caprice simple”; this is the
modern horizontal wheel. This wheel is similar in arrangement to the
vertical above-mentioned, except that its cases are arranged so that
the first plays horizontally in the plane of the wheel, the next at an
angle downwards, and the third upwards. This succession is repeated
with the remaining three cases. In addition, the horizontal wheel has
either a mine which is lit from the last case, or Roman candles and
mine, at the centre playing upwards. The second form is arranged so
that the Romans are fired simultaneously with the fourth case and the
mine from the last.

The wheel given by Ruggieri has a gerb in the centre. He explains that
Caprice is a generic name applied to all horizontal wheels which vary
the direction of the fire when revolving. However, at the present time
the name Caprice is only applied to a wheel with three tiers of three
cases, each similar in appearance to three single triangle wheels
superimposed at distances about equal to their diameter, the grooves in
the end of the spokes being so arranged as to vary the direction of the
fire. The cases are led up in the following order—one case horizontal,
one up, one down, one horizontal, two cases one up and one down, four
cases in each direction and one vertical. For a compact piece this is
one of the most effective made.

A similar piece is the Furiloni Wheel, which has, however, two tiers of
three cases each.

Jones describes a furiloni wheel which is more elaborate, having
twenty-five cases. His method of leading would, however, not be so
effective as the modern wheels of this type. The cases used for these
wheels are charged with a steel mixing formerly known as brilliant fire.

He mentions two other devices—Caprices petans and Caprices des pâtés.
The first of these was a modification of the piece formerly used in
this country as the balloon wheel. It consisted of a solid wheel round
which are a series of mines which discharged in succession as each
turning case lit. The second was similar but more elaborate, having
rockets as well as mines, and was a variation of the rocket wheel.

In his description of the Girandole, he explains that it is composed of
two horizontal wheels one above the other. This is the form taken by
the rocket wheel as fired in this country which, as we have seen, was
known as the girandole wheel. Ruggieri, however, appears not to have
used rockets on his girandole.

The last device he mentions in this class is the Spirali, which
consisted of a framework in the form of a cone, round which was wound a
spiral of cane fitted with lances.

A very effective piece, not mentioned by Ruggieri, is the revolving
fountain; it consists of a wood centre bored to turn on a vertical
spindle. The centre has two spokes fitted with gerbs for turning, and
has playing vertically a large gerb and Roman candles. The turning
gerbs play tangentially and slightly upwards.

Jones describes a similar device under the name of “illuminated spiral
wheel”; also two other horizontal pieces—the spirali and the plural
wheels, which approximate to the furiloni and caprice wheels of the
present day.

The spiral and helix are much used in larger devices, and the use of
modern lancework and colour has greatly added to their effect.

Ruggieri’s next division deals with built-up lancework pieces such as
the globe, which it was thought worthy of separate mention in his time,
but to-day is included with many devices of this nature too numerous to
mention, forming, as they do, a large proportion of the mechanical and
other pieces used in display work.

[Illustration: A Display ready for Firing, Dresden, September 1st,
  1899. Firework Portraits of the King and Queen of Saxony on the
  right, Bismarck second from the left.]

He then deals with tourbillions and table wheels. The latter
consisted of a circular table with a central pivot, round which is free
to revolve a bar which forms the axle of a wheel, the hub of which runs
on the edge of the table. When the wheel is turned, the hub running on
the edge of the table moves it forward in a circular path round the
pivot. This principle is applied to similar and more elaborate devices.
The name tourbillions, as before mentioned, is by other writers
differently applied.

The section dealing with cut-out and transparent devices is of little
interest. These devices were an attempt to give variety from the
monotonous repetition of turning cases and gerbs. To-day the use of
colour cases, lances, a much-enlarged range of fountain and similar
compositions, including aluminium and other brilliant fires, has
obviated the employment of effects which cannot be rightly considered
as pyrotechnic.

The moving and stationary pieces considered in this and preceding
chapters give a good general idea of the firing methods in compound
fireworks. As we have already noted, the difference of designs and
effects at the present time is infinite, so that it would be impossible
in a work of the present size to give anything approaching a complete
survey of what has been accomplished. But it is hoped that enough has
been said to give the reader some idea of the methods adopted and the
lines upon which the modern pyrotechnist works.




                              CHAPTER VII

                         FIREWORK COMPOSITIONS


It may have been remarked in the foregoing chapters that, although the
ingredients composing the firework mixtures are given, generally the
proportions are not.

The reason for this is two-fold: primarily, as we have seen in the
chapter on rockets, the proportion of the ingredients of a firework
varies in accordance with its size. So that to give the proportions of
the compositions of any one type of firework would often require as
many formulæ as there are sizes.

Secondly, and perhaps more importantly, the quality and purity of
chemicals as supplied in bulk vary so enormously that a constant
series of experiments has to be conducted in order to ascertain what
modifications and adjustments are necessary in the formulæ to give the
required standard of performance.

It is not meant to suggest that the impurities generally to be found in
bulk supplies are necessarily harmful to pyrotechnic results. This is
not so; salts give far better results in their natural or mineral form
than do those prepared synthetically. As an example of this saltpetre
may be cited. For pyrotechnic purposes the best obtainable is that from
Bengal, yet an analysis of this would probably be found to be less pure
than that synthetically prepared in Germany. But experiments have shown
that samples of the latter, taken from the same cask, but in different
parts, produce very distinctly varying results pyrotechnically.

Pyrotechny is an art, chemistry is a science, and although it is
impossible to deny that the former is greatly indebted to the latter
for the supply and production on a commercial scale of chemical
ingredients, yet it is possible to overestimate the position of
chemistry in the art, or possibly it might be more correct to say that
pyrotechny has its own chemistry.

Chemistry without pyrotechnic experience is apt to lead to erroneous
conclusions. To take a concrete instance: in an article in a famous
encyclopædia, obviously written by a chemist of standing, a portion
deals with the use of metal salts in the production of colour; the
writer gives copper as producing green, which no doubt it does in
the laboratory; in practice, however, copper is used solely for the
production of blue.

The question of purity in chemicals used in pyrotechny is a secondary
consideration, that is, of course, as long as the adulterants have no
adverse effect either as regards the pyrotechnic result or the safety
of the worker in manipulation. What is of first importance is its
pyrotechnic suitability, that is, it must produce the required result
and must be consistent. Unequal results are the bugbear of the firework
makers. As we have seen, constant experiments are necessary to keep an
even standard, but with irregularly functioning chemicals these would
be multiplied to an impossible degree.

The first group of compositions for consideration is that nearest
related to gunpowder, in fact, for the purposes of a work on
pyrotechny, gunpowder may be considered a particular case of this class.

The governing principle of this group, and one may say of all firework
compositions, is the same. For combustion to take place oxygen must be
present. When an inflammable article such as a piece of paper is set
on fire it takes up oxygen from the air. A pyrotechnic composition,
however, is so arranged that one of the ingredients has a supply of
oxygen which it is ready to give up; another, or others, are of a kind
ready to receive and combine with this oxygen.

The oxygen-supplying ingredient which is by far the most frequently
used is saltpetre, or, as it was formerly called, nitre, known
chemically as nitrate of potash.

Saltpetre may be said to be the basis of pyrotechny. There is hardly a
formula by any of the writers on pyrotechny up to at least the middle
of the nineteenth century which does not contain it.

Gunpowder is composed of saltpetre, sulphur, and charcoal, three
chemicals which it will have been gathered from the previous pages
play a prominent part in very many of the pyrotechnic compositions. In
some compositions their proportion is apparently identical with that
of gunpowder, yet they do not form gunpowder as they are not milled,
and are consequently not so intimately mixed. Compositions containing
these ingredients have frequently an admixture of mealed gunpowder, the
function of which is to give additional fierceness when required, as is
the case in some rocket mixings.

These chemicals, as we have seen in the previous chapters, are the
components of rockets, turning cases, tourbillions, saxons, Roman
candle fuse, and many others. When variation was required in fireworks
used to give a simple fountain effect the earliest addition was of
metal in finely divided particles, as filings, borings, or the now
almost obsolete iron sand.

Steel filings were used in what was known as “brilliant fire,” a term
which has fallen into disuse since the introduction of other metals
whose effects eclipsed that of steel. It has also been used where extra
effect is wanted, that is, more tail in rockets and tourbillions. It
is, however, not much used in the former case to-day, as the presence
of steel in a composition which is to be charged on a steel spindle
introduces a decided element of risk into the operation.

The introduction of steel and iron was the first use of metals in
firework making, probably the next metal to be introduced was
antimony, either black (sulphide) or regulus. Jones (1765) was already
using what he calls crude antimony; this was probably the black
sulphide.

Before the introduction of genuine colour, and while the chemicals
which had been adopted for pyrotechny were still very limited in
number, attempts were made to obtain either a semblance of colour or
some variety in stars and garnitures by the addition of such substances
as powdered glass, brass, sawdust, beech raspings, which appear to
have functioned as do the iron or steel in the compositions already
discussed, except that there would be no coruscation even with the
brass. These additions would merely show as red-hot particles in the
jet of fire.

Kentish gives two gerb compositions, one of which contains coke grains,
and the other porcelain grains, which would apparently produce cognate
results; the use, however, of both these ingredients is now almost if
not quite obsolete.

Antimony, on account of its ready combustion, is more completely
consumed before leaving the case. In this connection it may be
mentioned that care is necessary in a mixture containing steel or iron
to avoid too large a proportion of the oxygen-bearing ingredient, for
fear of consuming it inside the case.

Another composition producing remarkable coruscations is the
old-fashioned “spur fire,” which consists of saltpetre, sulphur, and
lampblack. This composition requires very careful and experienced
mixing, or no effect will be produced, rendering its preparation a very
lengthy process.

This difficulty was somewhat overcome during the last century by the
addition of orpiment or sulphide of arsenic. Even with this addition,
however, its manufacture requires care and patience. It is a curious
fact that this composition, unlike most others, has the quality of
markedly improving by keeping. How the lampblack produces this unique
effect, or why its effect should be so different from that produced by
any other form of carbon, has not been satisfactorily explained.

The compositions we have been considering fall into one of two classes,
namely, those to produce force and those to produce sparks. These
two classes, with one other, namely that of colour, may be said to
include all the modern recreative firework compositions. Up to the
end of the eighteenth century the ingredients used in the production
of the compositions of these three classes were very few in number. A
considerably larger number went to supply the ingredients for a fourth
class now almost extinct, these might be called the flame-producing
class. The principle on which these compositions were designed was,
as it were, to overload a mixture of saltpetre and sulphur with
combustible material; this latter took the form of gums, resins, or
fats, the object being to produce a reddish or golden coloured flame.
The early writers give formulæ for variously coloured stars and fires,
which must have required considerable effort on the part of the
observer for identification. These belonged to the flame class.

Frézier, with more perception than most of the others, realised the
shortcomings of such compositions, merely designating them greenish
(_verdâtre_), yellowish, reddish, and russet. The only colour which
he professes to produce distinct is blue, which he obtained with pure
sulphur.

Progress from the earliest times of pyrotechny up to the first
quarter of the nineteenth century was very gradual and very slight.
The chemicals used by Bate and Babington in their actual pyrotechnic
compositions were as follows:—Gunpowder and its constituents, camphor,
pitch, resin, orpiment, linseed oil, both pure and boiled, oil of spike
(_spica lavandula_), oil of petre (rock oil), an oil known either as
benedict or tile, varnish (probably amber), iron scales, and aqua vitæ
(spirits of wine).

[Illustration: Diagram Illustrating the evolution of Pyrotechnic
  Composition.]

Bate extends this list considerably by the ingredients of a series of
compositions which he has evidently taken from some alchemistic work.
These compositions are all either designed to burn under water or to
ignite spontaneously in water, and fall somewhat outside the bounds
of our subject. Frézier also includes these, evidently from the same
source.

Bate also refers to a liquid, the recipe for which was probably taken
from the same work.

“Aqua ardens.” The following are his directions for preparing it:
“Take old red wine, put it into a glassed vessell, and put into it of
orpiment one pound, quicke sulphur halfe a pound, quicke lime a quarter
of a pound; mingle them very well, and afterwards distill them in a
rosewater still; a cloth being wet in this water will burne like a
candle and will not be quenched with water.”

It is difficult to see what he obtained by this process differing from
spirits of wine. The quicklime would serve to dehydrate the wine, and
probably no part of the orpiment or sulphur would be taken over in the
distillation.

Rather over a century later we find Frézier and Jones have made
some additions to the ingredients of pyrotechny, the most notable
innovations being the use of iron filings (not to be confused with
the iron scales of Bate, which were probably hammerslag, the magnetic
oxide of iron), steel filings and pulverised cast-iron. Beyond these,
and the spark-producing agent already mentioned, the other additions
are of small importance, the most notable being lapis caliminaris, or
the mineral carbonate of zinc, which however was not used as are metal
salts to-day, that is, for the production of colour.

Jones’s book, written some years after that of Frézier, shows little
advance from the latter as far as pyrotechnic results are concerned.
What he has done, however, is to eliminate what might be called the
alchemistic, or one might almost say magic element with which it is
pervaded.

In attempting to classify the compositions in Frézier’s book one
is staggered by the grotesque character of many of them and by the
extraordinary variations in the proportion of their ingredients, even
amongst compositions designed for a similar effect.

Presumably with the intention of impressing his readers with the
wonders of the science, he added ingredient after ingredient, which, if
they did actually no harm to the composition, certainly in no degree
assisted its functioning.

In what he calls a simple star there are eleven ingredients, of which,
in fact, four only are essential.

Further, beyond the multiplication of unnecessary ingredients in
individual compositions, there is often their incompatibility and
innate unsuitability for the purpose. Such components as ink, onion
juice, and the drainings of a dung-heap suggest so strangely the
formulæ of the alchemists that one almost expects to come across “the
hair of a Barbary ape,” or similar absurdity.

Ruggieri, who may be considered as the last of the old school, is the
first author to deal with the subject in such a way as to convince the
professional reader of the practical knowledge of the subject.

His additions to the list of ingredients are not many, but they are
genuine. He is the first writer to make use of metals or their salts
in the production of colour; he includes among his chemicals metallic
copper and zinc, also the acetate and sulphate of copper, and chloride
of ammonium. The notable advance in his colour compositions, besides
the use of metal salts for that purpose, is the introduction of a
chloride, which has the effect of improving the colour by assisting in
the volatilisation of the metal. For this purpose he used sal-ammoniac,
the use of which has now been almost discontinued on account of its
hygroscopic nature, notwithstanding that its base of ammonium is very
useful in compositions containing copper. Its place is now generally
taken by calomel; in such compositions chloride of sodium had been used
for many years, but not as a chlorine carried. Ruggieri appears to have
been the first to produce colour on anything approaching modern lines,
and although he did not progress greatly, what he did achieve was
undoubtedly a marked advance in the art.

His account of the invention of this composition is interesting. He
says that he was told by a returned traveller from Russia of a set
piece representing a palm tree, “the colour of which rivalled nature.”
This piece he set out to imitate, which he did, at any rate to his own
satisfaction. The result he obtained would undoubtedly give a good
colour, if the method of firing was very clumsy. He remarks that he
does not know if his method was as that adopted in Russia, and later of
the “merit if not of discovering a new fire at least to have imitated
or rather to have rediscovered it.” It appears, therefore, that there
may be some doubt as to the originality or priority of Ruggieri’s
achievement in this direction, but he must be credited at least with
independently arriving at the result. Indeed it is more than probable
that the piece seen in Russia was quite different, a transparency
or illumination, either imported or copied from the work of Eastern
pyrotechnists, and that the whole credit of introducing colour into the
art belongs to Ruggieri and to him only.

He mentions that he puts it on record with the object of “thus
preventing writers from attributing it to the Chinese, the Medes, or
Arabs, as is the custom in Europe, and above all in France, where more
than elsewhere there is a mania for enriching foreigners with our
merits and to rob ourselves of the birthrights of genius.”




                             CHAPTER VIII

                     MODERN FIREWORK COMPOSITIONS


Ruggieri may be regarded as the last of the ancients. It is true that
his book shows a marked advance on anything that had gone before,
also that he appears to have been one of the first, if not actually
the first, to introduce the use of metal salts in the production of
colour. But he makes no reference to the use of chlorate of potash, and
it is the introduction of this salt into pyrotechny which marks the
commencement of the modern epoch of the art.

This earliest use of chlorate, or as it was then called, oxymuriate
or hyperoxymuriate of potash, appears to have been soon after its
discovery in 1786 by Berthollet. Samuel Parkes, in a work on chemistry
written in 1811, says: “The shocking death of two individuals in
October, 1788, and the burns others have suffered by it, render it
feared by chemists in general,” that is in conjunction with sulphur and
charcoal.

He later remarks that notwithstanding this accident “the French have
since —— actually employed in one of their campaigns gunpowder made
with oxymuriate of potash instead of saltpetre,” and adds that a Scotch
clergyman had taken out a patent for the use of a powder containing
chlorate of potash to be fired by percussion.

This patent, granted in 1807, is the first for the percussion system in
firearms.

The use, however, of chlorate of potash in propellant compositions
presents no very great advance in pyrotechny, however revolutionary
may have been the introduction of the percussion system into the
manufacture of firearms.

It is its use in the production of colour that marks the modern epoch.

The exact date of this innovation appears to be about 1830.

A Belgian lieutenant of artillery, Hippert by name, published in 1836
a translation of a work by Captain Moritz Meyer, of the Prussian
Artillery, on the application of chemistry to artifices of war.

In a chapter devoted to coloured fires he gives several formulæ
containing chlorate of potash. Although this appears to be the first
published notice of its use, it seems likely that by the time the book
was published that it was fairly well established.

Meyer concludes his remarks on coloured composition by saying that the
English at that time made use of coloured rockets for signalling at
sea, and had succeeded in producing ten different shades, “which are
quite sufficient for the purpose of signalling particular pieces of
information.”

This seems rather to indicate that the elaboration if not the first
introduction of chlorate of potash into pyrotechny may be attributed to
this country.

His mention of ten distinguishable tints, however, is somewhat
optimistic. During the late war it was found that to avoid any chance
of a mistake in code signals only three colours could be used for
long-distance signalling, namely, red, green, and white.

It is curious that Meyer makes a mistake over the first composition
he mentions. He describes a light composition of chlorate of potash
and sugar, which he says burns with a red light. In fact, however, the
light so produced is a bluish white, similar to the so-called blue
shipping light.

The directions he gives for the preparation of other colours are as
follows:

“A powder which burns with a green flame is obtained by the addition of
nitrate of baryta to chlorate of potash, nitrate of copper, acetate of
copper.

“A white flame is made by the addition of sulphide of antimony,
sulphide of arsenic, camphor.

“Red by the mixture of lampblack, coal, bone ash, mineral oxide of
iron, nitrate of strontia, pumice stone, mica, oxide of cobalt.

“Blue with ivory, bismuth, alum, zinc, copper sulphate purified of its
sea water (_sic_).

“Yellow by amber, carbonate of soda, sulphate of soda, cinnabar.

“It is necessary in order to make the colours come out well to animate
the combustion by adding chlorate of potash.”

These formulæ, if somewhat incoherent, and clearly showing a want of
experimental verification, indicate a real advance in pyrotechnic
chemistry, not only by the addition of chlorate of potash, but by the
multiplication of the number of metal salts used.

At the same time it is evident that the old alchemistic ideas were not
entirely extinct by the use of such ingredients as ivory, mica, and
pumice stone.

However, there can be no doubt that from the third decade of the
nineteenth century dates the modern era of the pyrotechnic art. From
this date onward chemical ingredients, metals and their salts as they
were provided by the commercial chemist were eagerly taken and tested
by the pyrotechnist, and adopted or rejected on their merits. And from
this date begins the rapid elimination of useless additions.

Of those compositions given above the following salts are at present
in use: nitrate of baryta, sulphide of antimony, sulphide of arsenic,
nitrate of strontia, copper sulphate, carbonate of soda, and chlorate
of potash.

Zinc, alum, lampblack, and oxide of iron are also used, but not for the
purpose indicated.

Nitrate of copper and sulphate of soda would both be valuable
ingredients, but their unstable nature prevents their use under modern
conditions.

Meyer also describes the use of salts to tint an alcohol flame, which
is merely an elaboration of Ruggieri’s palm tree and of little interest
at the present time.

The next name prominent in pyrotechny is that of F. M. Chertier, who
published in 1854 his “Nouvelles recherches sur les feux d’artifice,”
after having published a pamphlet on the subject about twenty-five
years previously.

In this work Chertier devotes most of his attention to the subject of
colour, and although new ingredients have been introduced which were
either unknown or were not then available on account of expense or
other causes, since the time of his writing, yet there can be no doubt
that Chertier stands alone in the literature of pyrotechny and as a
pioneer of the modern development of the art.

Tessier, in the introduction to his “Treatise on Coloured Fires,”
published in 1859, whilst paying tribute to Chertier’s work, regrets
that he only possessed “quite superficial notions of chemistry.” Here
speaks the chemist. The writer recently asked a pyrotechnic chemist of
many years’ experience, whose knowledge of pyrotechnic chemistry is
probably second to none, his opinion of Tessier’s book, and received
this answer. “Tessier’s book contains too much chemical theory and too
little pyrotechnic practice.” There speaks the pyrotechnist.

The writer, as he has before remarked, has no wish to belittle the
value of the chemist’s work in relation to pyrotechny, but a knowledge
of chemistry is not the most important attribute of the successful
pyrotechnist.

As in other arts so in pyrotechny, experience and natural aptitude are
the first essentials.

Chertier may have had little knowledge of chemistry, but in spite
of or perhaps because of his lack of chemical knowledge, he was able
to produce a work which, from the point of view of the practical
pyrotechnist, has never been equalled.

His researches were conducted by practical experiments; he had one
end in view, namely, pyrotechnic effect, and by exhaustive trials of
the materials obtainable, unbiased by theoretical consideration, he
succeeded in advancing the art to a stage undreamed of a few years
previously. It is true that many of his formulæ are not in use to-day,
in this country that is, on account of the danger of using sulphur or
sulphur compounds in conjunction with chlorate of potash; but there can
be no doubt that his writings and research work laid the foundation of
modern pyrotechnic practice.

Once the theory of colour production was established, that is to say
the volatilisation of a metal salt in a hotly burning composition, it
was a matter of less difficulty to either eliminate the sulphur, which
was present chiefly as a burnable, or to replace it.

This prohibition, as we have seen, took place in 1894, under Order
in Council 15, and affected the production of coloured fireworks far
less than might have been anticipated. During the period between the
introduction of chlorate of potash and the Order in question, the
development of commercial chemistry had increased greatly the number
of chemicals available in pyrotechny, so that in some few cases it was
found possible to replace the chlorate.

In addition, moreover, most of the leading makers, anticipating
some form of restriction on this admixture, had been for some time
previously seeking substitute colour formulæ, and although it may be
said by some that colours were obtained by the use of chlorate and
sulphur which have not been equalled by subsequent formulæ, yet most
have not only been equalled but improved upon, and the small minority
remaining are an insignificant price to pay for the security and
safety gained in manufacture.

Between the publication of Chertier’s book in 1856 (nearly thirty years
later than his first pamphlet) and the close of the century, several
works on pyrotechny made their appearance, several by Frenchmen:
Tessier, 1859, “Traité Pratique des Feux colorés,” two works in the
Roret encyclopædia series, “Pyrotechnie Civile” and “Pyrotechnie
Militaire,” published 1865, and in 1882, “Traité pratique des Feux
d’Artifice,” by Denisse.

The English works of any value during this period were: “Pyrotechny,”
by Practicus, Brown’s “Practical Firework Making,” and “The
Pyrotechnist’s Treasury,” by Kentish, 1878. Hutstein and Websky’s “Art
of Firework Making,” published at Leipzig in 1878, a book published
under the same title by Oscar Frey about 1885, and “A Theoretical
and Practical Treatise of Civil Pyrotechny,” by Antoni, published
at Trieste in 1893, together with some works on military pyrotechny
published both in Europe and the United States, complete the list.

Some of the military works are of considerable value, but are chiefly
directed to the study of rockets and signals; some, however, are in
the same category as “The Artillerist’s Manual and British Soldier’s
Compendium,” by Captain F. A. Griffiths, R.A., published in 1852. The
section dealing with fireworks in this work might almost be taken as
an attempt to be humorous on the subject. The author quotes in all
seriousness formulæ dating from the days of Bate and Babington, and
knows so little of his subject that he gives instructions for making
the same firework under different names under the impression that
they are distinct units, the information being obviously pillaged
from earlier writers. Generally a study of the above-mentioned works
indicates that the tendency in pyrotechnic compositions has been
in the direction of simplification. During the eighteenth century
the useless ingredients had been in a great measure eliminated. The
“burnables” had been reduced from a long list of alchemistic survivals
to a mere half-dozen or so.

Gums had been reduced practically to shellac alone (the use of gum
arabic as an adhesive is quite distinct), carbons to lampblack and
charcoal, and these with sulphur and sulphides of antimony and arsenic
practically completed the list.

Of the metals the use of pure zinc, copper, and brass has been
discontinued, and the two almost revolutionary additions of magnesium
and aluminium made, the former about 1865 and the latter in 1894.

The date of the introduction of these metals marks almost as great
advances in the art as did the introduction of chlorate of potash. Not
only are they used as spark-producing metals in the same way as are
steel and iron, but they are also used as “burnables,” that is, they
are consumed inside the case; and many of the present-day firework
compositions owe their brilliance to one or other of these metals.

It is, however, in colour compositions that the tendency towards
simplification is most strongly exhibited. In Kentish’s book colour
compositions containing as many as seven or eight ingredients are
common, whereas to-day formulæ containing over four are the exception
rather than the rule.

[Illustration: Roman Candles. This untouched photograph illustrates
  the extraordinary brilliance of aluminium compositions. Each
  “plume” (200 ft. high) is produced by a single star about ¾ in.
  diameter and ¾ in. long. Each line is a microscopic particle of
  aluminium.]

The reason for this complexity is not easy to follow, but it may have
been in some measure due to the difficulty of obtaining sufficiently
finely ground chemicals before the days of machine grinding; in some
cases it was found that by melting two of the ingredients together
and allowing the mass to cool they could be ground with greater ease.
Chertier went so far as to melt shellac and salt together, grind them
and remove the salt by dissolving in water. Also by adding a finely
ground chemical of similar action to one only coarsely ground a better
result was obtained.

Whatever may have been the reason, there can be no doubt that, except
for secondary shades, the fewer the chemicals used the more brilliant
will be the resulting fire.




                              CHAPTER IX

                          MILITARY PYROTECHNY


The use of pyrotechnic mixtures for military purposes is the basis of
artillery, and one might almost say the foundation of chemistry. Before
the age of the alchemist men were at work endeavouring to produce some
weapon which would give them an advantage over their enemies. Of the
natural phenomena none made so strong an appeal as fire, which from
earliest times had been a mysterious and therefore terrible element.

The early use of fire or pyrotechnic mixtures gave the users so decided
an advantage over their enemies that their use was chronicled by
historians of the day either on the side of the victors as a pæan of
praise for their invincible weapon, or as an excuse for defeat on the
side of the vanquished.

Such reports are necessarily vague and exaggerated, vague because
the writer had no technical knowledge of the subject, and the users
naturally wished for secrecy and exaggerated because exaggeration
increased the value of the weapon.

It is from such reports that we obtain our information about Greek fire
and similar compositions, and when one considers that the translations
were generally biased, in most cases unintentionally but still biased,
in favour of reading into passages referring to fire or projectiles an
early reference to gunpowder, guns or some unknown pyrotechnic effect,
it is obvious that all information so gained must be accepted with a
considerable amount of reserve.

The translators, too, in many cases were men of no technical knowledge,
which made them even more prone to fall into errors which would be
avoided by the expert.

Of the mass of writing dealing with the subject, the work of two
writers stands out prominently—the late Mr. Oscar Guttman in his
“History of Explosives,” and Col. H. W. L. Hime in his “Origin of
Artillery,” whose observations cover the field of information on the
subject, although approaching from slightly different angles.

Neither, however, gives an exact explanation satisfactorily covering
the projection of Greek or sea fire. Col. Hime, rejecting earlier
theories, goes somewhat to the other extreme: he denies the knowledge
of saltpetre before the twelfth century, but attempts to explain the
phenomenon by the use of phosphide of calcium.

He premises four conditions to be filled by the weapon or apparatus.
These conditions are fulfilled by the explanation already briefly
touched upon on page 15, and the writer is convinced that this simple
although apparently little known phenomenon is the true explanation of
the terrible, mysterious Greek or sea fire.

If a mixture of saltpetre, pitch, and sulphur is charged into a long
tube sufficiently strong and ignited it will burn, giving off dense
smoke, for a short time, when it appears to choke momentarily. This
choking is followed by a more or less violent outburst, which may
be likened to a “cough,” projecting a burning mass of composition
to a considerable distance; the action is repeated with surprising
regularity during the burning of the whole of the composition
throughout the length of the tube, and will, the writer is confident,
satisfy any unbiased observer that here is the true explanation of the
phenomenon.

Let us see how the requirements mentioned by Col. Hime are fulfilled.
The first, “It was a wet fire,” _i.e._, its action necessarily
connected in some way with water or the sea, and as a matter of fact it
was used at sea with great success on many occasions. May not a “wet
fire” be a way of saying “a molten, viscous mass of fire”? The masses
would float and although some might become extinguished, some would
probably burn on the surface of the water; also its use at sea would,
with a range up to a hundred yards, be quite as easy as on land.

Secondly, “Its composition was such as could be kept secret at
Constantinople.” If, as Col. Hime says, saltpetre as such was unknown
at the time, it was only as a separate kind of salt. It was undoubtedly
known, but not distinguished from sea salt or nitrate of soda. Would
not this fact render the concealment of the ingredients used more easy?

Thirdly, “It burned with much noise and smoke.” Allowing for some
slight exaggeration the first condition is fulfilled, as undoubtedly is
the latter.

Fourthly, “It was necessarily connected in some way with syphons.” As
Col. Hime points out, there is ambiguity between the word syphon and
tube, and if the latter word meets the facts it seems the more likely
rendering.

The writer saw this effect produced during experiments with
smoke-producing compositions, and it is probable that the mixture in
question was not in the most effective proportions, but so striking was
the result that there is little doubt that experiments on such lines
would produce a terrible and effective weapon under the conditions of
warfare then in existence.

The “Dictionnaire Mobilier Français” gives a diagram of a weapon of a
somewhat similar nature stated to have been used by the Arabs in the
fifteenth century. The illustration shows what is virtually a Roman
candle, and appears plausible until one considers the facts. What is
most probable is that the weapon, which was of an incendiary nature,
was similar to that described above, which fulfils the requirements of
the description without assuming a knowledge of compositions which at
the time did not exist.

From the period of Greek fire onward military and recreative pyrotechny
appear to have marched side by side.

As we have seen, the progress in the latter branch was extremely slow,
so with the former, and it was not until the introduction of modern or
comparatively modern methods that real progress commenced.

With the progress came divergence, the introduction of the rifled bore
in artillery, and of nitro compounds and high explosives whose dynamic
force exceeds many times that of gunpowder, which however useful they
might be to the artillerist, were of little value to the recreative
pyrotechnist. It was not until the great war that the resources of
pyrotechny were fully realised and utilised by the military. It is
curious to note that just as the tactics and methods of warfare
eventually adopted—although on an unprecedentedly large scale—were
in a great measure those of centuries before, so military pyrotechny
returned to ideas just as antiquated. With the advantages of modern
science, and by the assistance of knowledge gained in the development
of recreative pyrotechny, the progress made in a month or so in
military pyrotechny during the war may, without exaggerating, be said
to have exceeded that of previous centuries.

Speaking generally, the use of pyrotechny in warfare, or indeed any
science, has two objectives, the first to destroy or embarrass the
troops of the enemy, and secondly, to assist one’s own.

Until the late war it was the first of these which received by far the
greater attention, and it is but natural that the introduction of the
modern methods mentioned above should have provided means which left
pyrotechnics far behind. In the second division, however, pyrotechny
triumphed.

Of the offensive type the earliest use of pyrotechny was the
incendiary. Greek fire, wild fire, and similar compositions have been
used from time immemorial to set fire to enemies’ works or ships or to
injure his personnel. And just as incendiary compositions antedated
the propellant, so the incendiary shell appears to have preceded the
explosive.

Incendiary projectiles of the past were known as carcasses; the
earliest form appears to have been a canvas bag or container pitched
over on the outside and bound with iron hoops, which, from their
likeness to the ribs of a corpse—according to “Chambers’ Encyclopædia”
(1741)—suggested the name.

The fireball was similarly constructed and designed for hand
projection, bearing the same relation to the carcass as does the
grenade to the bomb.

The composition in most incendiary missiles consisted of a mixture of
saltpetre, sulphur, and pitch, with or without the addition of mealed
gunpowder.

The most recent form of carcass was a spherical shell of iron, having
three vents, and filled with incendiary composition. This projectile
became obsolete in the Service at the end of the last century.

Another form of pyrotechnic projectile was that designed to give out
smoke, either with the idea of rendering the atmosphere of works or
casemates unbearable to the defenders (a principle revived in the late
war by the use of poison gas), or to hinder them by obscuring their
vision either by firing a smoke cloud in their (the enemy’s) works, or
so placed as to hide one’s own troops.

It is open to discussion if the use of smoke is not indeed of greater
antiquity than that of incendiary missiles, but it is probable that
its origin was its production by the combustion of grass or similar
material, and not with pyrotechnic composition.

Read’s “Weekly Journal” of October 25th, 1760, in an account of a
review in Hyde Park, mentions as the concluding item of the manœuvres,
that “pieces of a new construction, of a globular form, were set on
fire, which occasioned such a smoke as to render all persons within a
considerable distance entirely invisible, and thereby the better in
time of action to secure a retreat.” There can be little doubt that
this is one of the first demonstrations, at any rate in this country,
of the use of smoke balls.

The Chinese made use of both projectiles many centuries ago, and the
smoke—or stink-pot—was in use by them until comparatively recently.

Smoke balls from 4⅖th inches up to 13 inches calibre were included in
the official list of projectiles for smooth-bore guns until about 1873,
when with ground light balls they became obsolete. The latter, as their
name suggests, were intended to be burnt on the ground and light up
enemy working parties, etc. This also was the object of the parachute
light-ball, which was fitted with a time fuse and an opening charge;
upon opening, a light was ignited suspended from a parachute. This
method appears to have been invented in Denmark in 1820, and they were
used in Austria the following year.

Another class of war store which naturally suggests itself is that used
to give light for the purpose of signalling. The light is either burnt
on the ground as a hand light or fitted to a rocket. Fireworks for
this purpose have been in use from earliest times, being the logical
development of the signal beacon, but it was not until the introduction
of genuine colour—that is to say, colour distinguishable at a long
distance—that they reached their full standard of utility.

It is, however, the rocket which has received most attention for
military purposes, and certainly with good reason. Here was a
projectile which, in the days of smooth-bore ordnance had a good
range and required no heavy gun or transport. Moreover, it formed
its own time fuse. Congreve wrote: “Rockets are ammunition without
ordnance, the soul of artillery without the body.” Many methods of
fitting up rockets for warlike purposes have been evolved, invented and
re-invented, most of which for practical purposes were useless.

It is the military use of the rocket, however, which presents the most
interesting study in military pyrotechny.

There are several early references to what is supposed to be the use of
rockets in warfare. The Paduans are stated to have burned the town of
Mestre with these projectiles.

Orleans used rockets in its defence in 1429, and Dunois fired them in
1449, when besieging the town of Pont-Andemer. In 1452 they were used
against Bordeaux, and the following year at Gand.

Rockets were employed in 1586 for lighting purposes and as projectiles
against cavalry. The description seems to indicate a method of fitting
up to produce a similar effect to a shrapnel shell.

Hanselet, writing in 1630, refers to rockets with grenades attached.
Casimir Siemienowitz, Lieut.-General of the Ordnance to the King of
Poland, published in 1650 his “Great Art of Artillery,” which contains
a treatise on fireworks both for civil and military purposes. He refers
to a work on the military use of fireworks written ninety years before,
and speaks of rockets up to 100 lbs. and describes their construction.

A French work published in 1561, entitled “Treatise upon several kinds
of War-Fireworks,” suggests a rocket case of varnished leather.

It is on record that in 1688 trials were made in Berlin with rockets
of 50 lbs. and 120 lbs., which carried a bomb weighing 16 lbs. The
composition was nine parts saltpetre, four parts sulphur, and three
parts charcoal. The case is stated to have been of wood covered with
linen.

Hyder Ali is credited with making considerable use of rockets
against our troops in India; he is said to have had a corps of 1,200
“rocketers” in 1788, whilst later on, his son, Tippoo Sahib, employed
as many as 5,000, and Captain Moritz Myer, writing in 1836, ascribes to
experience of these weapons so gained the efforts made in England to
bring them to perfection.

He also describes the Indian rocket as “an iron envelope about 8 inches
long and 1½ inches in diameter, with sharp points at the top. The stick
of bamboo 8 or 10 feet long, but sometimes consisting of an iron rod.
They were hand-thrown by the rocketers, and did much damage to the
cavalry.”

This description, which, to say the least, is unconvincing, would seem
rather to refer to some other pyrotechnic missile.

Whatever may have been the cause, there was undoubtedly great interest
in the subject of rockets during the first half of the nineteenth
century. Sir William Congreve is perhaps best known in connection with
the work of this period. His efforts, however, were rather directed to
the development of existing ideas than to invention.

In 1804, after experiments at the Royal Laboratory, Woolwich, a
flotilla of boats was fitted out under his direction for the purpose
of bombarding Boulogne Harbour with incendiary rockets from frames
fixed on the decks. The first attempt ended in a fiasco owing to heavy
weather, but the following year better results were obtained, although
the rockets were deflected by the wind and did more damage in the town
than in the harbour.

In 1807 Congreve personally superintended their use at Copenhagen
with even better effect, and they were again used in the Walcheren
Expedition and in an attack on the island of Aix.

These rockets were all of an incendiary nature, with paper cases, and
fired at an elevation of 55 degrees. Myer gives the proportion of
the composition as 62.44 saltpetre, 23.18 charcoal, 14.38 sulphur.
This writer gives Congreve’s rockets little credit for efficiency,
but admits that they “attracted great attention and were regarded as
formidable.” He remarks that at the siege of Flessingen “the rockets
acted so badly that the English themselves said that they did more harm
to the battery than the besieged town.” He also states that as a result
of finding an “unburnt specimen” in the town after the bombardment of
Copenhagen trials were conducted by Captain Schuhmacher, although how
an unburnt rocket could reach the town is not clear; possibly he means
from a reconstruction of the remains collected.

These trials seem to have been successful, and in 1808 a rocket brigade
was formed.

In 1809 Admiral Cochrane used rockets upon the town of Callao, in
1810 they were used against Cadiz, and in 1813 in the battle of
Leipsic, where the commanding officer, Captain Bogeu, was killed, and
at the siege of Dantzic. It is interesting to note that during that
year they were used for propaganda purposes. At the siege of Glogau
proclamations, etc., were printed on thin paper and fastened to the
sticks with light thread. Rockets were used with effect at Waterloo,
the rocket detachment being directed by Sergeant Dunnet.

In 1813 Colonel Augustin, of the Austrian army, saw the English rocket
batteries in action and trials of Congreve rockets in London, and the
following year visited Copenhagen, where by arrangement between the
two Powers he was instructed by Schuhmacher in his method of rocket
construction.

The Austrian Government as a result established shortly afterwards an
extensive factory at Weinerisch-Neustadt for the manufacture of war
rockets.

Much work and ingenuity was expended about this time in seeking to
eliminate the necessity of the rocket stick. Congreve is credited with
introducing fins similar in action to the feathers on an arrow; this,
however, had been done nearly one hundred years previously, and Frézier
illustrates the method in his treatise.

A Mr. Heath, of Boston, is credited with having reached a range of two
and a half-miles with a five-pound rocket of this type.

Garnier in 1813 proposed to avoid the alteration in position of the
centre of gravity by using a wire or chain with a weight at the end
fastened to the centre of the rocket and hanging vertically. From
Ruggieri’s book it would appear that this idea had often been tried
previously.

However, the most successful series of inventions were those based on
the principle of the rifle, that to give the rocket a rotary motion in
its passage through the air.

In 1815 successful trials were made in America with rockets of the
rotary type, rotation being imparted by means of holes bored through
the case into the composition in an oblique direction.

Congreve established a factory at Bow for the manufacture of rockets
for the East India Company, and Captain Parlby, of the Bengal
Artillery, manufactured similar rockets, both being made to rotate,
probably on similar lines to the American model. The “Calcutta Journal”
of the period contains a discussion of the rival merits of Congreve’s
and Parlby’s rockets.

Hale patented a rocket constructed on similar lines as late as 1844,
the holes at the side of the case being nearly tangential. He also
gave his name to a service rocket—Hale’s 24 pr. and 9 pr. These were
constructed of iron with a wooden head, fitted metal plug at the base
with three vents, a tail piece or flange continuing from the base so as
to enclose half the periphery of each jet. This arrangement imparts a
rotary motion to the rocket.

In 1853 Macintosh patented a method of rotating the tube from which the
rocket was fired so as to give an initial rotary movement before the
flight commences.

The following year Fitzmaurice patented the idea of causing rotation by
a screw-shaped head, and Court a method by which the fire impinged on
surfaces inclined to the axis of the rocket.

In 1826 Congreve patented a method of fixing two or more rockets
together so that the heading of one ignited the next and so obtained a
longer time of burning; this method is, however, again anticipated in
Frézier’s book.

About this time all the leading Powers in Europe were manufacturing
rockets for war purposes, factories for their manufacture being
established at Warsaw, Turin, Toulon, and Metz. The Russians used them
at this period in their war with Turkey, firing them in salvoes of nine.

In 1831 a series of trials were made by the Swiss military authorities
of 6 lb. rockets fired from a 6 ft. tube, when a range of from 18–1900
yards was obtained, and three hits registered out of five were made at
1,100 yards.

Although great interest was aroused by the rocket for war purposes, it
quickly subsided, and it is now practically only used for signalling
and line-carrying purposes.

William Bourne, who describes himself as a “poor gunner,” the first
to produce an original book on artillery in this country, as distinct
from translation of continental works, makes the following observations
on military pyrotechnics: “Divers gunners and other men have devised
sundry sorts of fireworks for the annoyance of their enemies, yet as
far as I have ever seen or heard, I never knew any good service done by
it, either by sea or land, but only by powder, and that has done great
service for that the force of it is so mighty and cometh with such a
terror. But for their other fireworks it is rather meet to be used in
the time of pleasure in the night rather than for any service.”




                               CHAPTER X

                 MILITARY PYROTECHNY IN THE GREAT WAR


The outbreak of the great war, whatever may have been the case
as regards other branches, found the Service badly equipped
pyrotechnically. The great and almost frantic interest taken in
military pyrotechny during the first half of the nineteenth century
had died away. Gradually the pyrotechnic stores included in the
official schedule had been reduced until in 1914 a few rockets—mostly
signal—lights for signalling and illumination, Very pistol cartridges
for signalling purposes, with single stars of various colours, and
incendiary and light stars for shells constituted the entire list.

The cause of this neglect of the art of pyrotechny for warlike purposes
was not difficult to understand. Rifled barrels, breech-loading, and
quick-firing ordnance had entirely destroyed interest in the rocket
as a projectile. The telephone and telegraph had almost entirely
superseded older methods of signalling, and so with most of the
pyrotechnic contrivances which, less than a century before, had been
thought to be indispensable.

As events proved, this abandonment of old ideas was premature. Although
every thinking man in the country realised that war was some day
inevitable, no one, or at least very few, realised the nature of the
struggle. The development of land war into what were practically siege
operations on a gigantic scale; the nature of sea warfare with the new
factors, the submarine, seaplane and wireless; the extent and ferocity
of aerial warfare—all were unforeseen. Yet each of these called for new
inventions, new methods of destruction, new methods of protection and
communication, and in many cases the resuscitation of old ideas long
since abandoned.

And as fire has for all time been associated with the sword, it is
small wonder that pyrotechny played no inconspicuous part in the
struggle.

As has always been the case, and no doubt always will be, the outbreak
of hostilities was the signal for an epidemic of inventions. Men who
had never before interested themselves either in war, or in that
particular department of science to which their ideas belong, and in
spite of or perhaps because of an entire ignorance of the subject,
inundated the authorities with so-called inventions which were so much
waste of time to all concerned.

In this connection it is interesting to turn to a volume of
“Abridgements of Specifications relating to Fire-arms and Other
Weapons,” published by the Patent Office in 1859. The preface contains
the following remarks: “It is worthy of notice that a very large
proportion of the so-called inventions of the present day are, in
fact, old contrivances, sometimes modified and adapted to modern
requirements, but very often identical with what has been tried and
abandoned as useless long ago. From the year 1617 down to the end
of the year 1852, not more than about 300 patents were granted for
inventions relating to fire-arms. When the war with Russia broke out
the Patent Office was inundated with applications for Letters Patent
for similar inventions, and about 600 have since been actually granted.
Of these it may be safely said that five-sixths of the applications
related to old contrivances which have been patented over and over
again.”

Many of these inventions recall a story of the Duke of Wellington,
who was examining a steam rocket invented and patented by a Jacob
Perkins in 1824. This device consisted of an iron case with a stick
like that of a rocket. The case was filled with water and had a
fusible metal plug at the base. The case was heated, and when the plug
melted the generated steam escaped and impinging on the air drove
forward the projectile. The absurdity of the idea is too obvious to
need discussion. The Duke carefully examined it, and after asking many
questions, remarked: “If this had been invented first and gunpowder
afterwards, what a capital improvement gunpowder would have been.”

The great war saw these “inventions” multiplied a thousand-fold. The
spread of education, the availability of books from which at least a
smattering of any subject could be obtained, and from the increase both
in quality and quantity of newspaper news a consequent closer knowledge
of what was happening—all these factors helped to add to the crop
of ideas. In many cases undoubtedly these ideas were elaborated and
worked out by the inventor, adopted by the authorities, and proved of
the highest value. These cases were, however, greatly in the minority,
and were generally the work of one who had at least some pre-knowledge
of his subject. Such a man was the late Wing-Commander F. A. Brock,
R.N.A.S., of whom it can be said without fear of contradiction no one
man did more for military pyrotechny during the great war, and possibly
in no other single subject during the war was one man so invaluable.

Born in 1884, educated at Dulwich, he entered the firm of C. T. Brock
and Co. in 1901, where he remained until the outbreak of war. Endowed
with a marked inventive ability and a phenomenal memory, and brought
up as it were in an atmosphere of pyrotechny, he developed a knowledge
of pyrotechnic chemistry which was extraordinary and appeared almost
instinctive.

A naval correspondent, writing in “The Navy,” speaks of him as follows:
“From H_{2}O to WO_{2} they knew all about it, or thought they did
until the wayward genius of the Commander, who never pretended to be a
chemist, taught them that there were permutations and combinations to
the _n_th degree that they had never dared to think of.

[Illustration: WING-COMMANDER FRANK ARTHUR BROCK, R.N.A.S.

  Killed at Zeebrugge, April 23rd, 1918.]

“Wing-Commander Brock’s great secret was originality. To the accepted
formula he would add just a touch of the unexpected. The chemists would
say it can’t be done, or it wouldn’t work. Sometimes it did not, but
often it did, very nearly. And Brock’s pioneer brain touched it a bit
more—and lo! the impossible and the unexpected had arrived.”

During his connection with the firm he had travelled over a large
portion of the world on its behalf. His experience at a comparatively
early age in organising and carrying out large displays—where the
safety of thousands of spectators is in the hands of the directing
mind—no doubt did much to develop those qualities of self-reliance and
self-confidence which were so marked a characteristic of his Service
career.

Wing-Commander Brock was responsible for many pyrotechnic inventions,
and for the practical development of many ideas and inventions not his
own, but which required technical knowledge and experience to ensure
success.

It is perhaps as the “inventor of the smoke screen” that he is
best known, a quite mistaken idea, the fallacy of which a moment’s
consideration will show. There are many references to the use of smoke
as a screen in classic times and even in mythology. The smoke ball,
as we have seen, was a recognised military store up to the middle of
the last century. It is just as absurd to credit Commander Brock, or
for that matter any living man, with the invention of the use of the
smoke screen in warfare as to credit the inventor of a patent fire
extinguisher with the idea of putting out fires.

What Commander Brock did do was to provide the means when the demand
arose of producing smoke suited to the particular purpose for which it
was to be used, whether for screens, signalling, or other purposes.

As an example the “E” float may be cited. A demand had arisen for a
smoke-producing device for use on board merchant ships to assist escape
from enemy submarine attack. Commander Brock, with characteristic
energy, in a very short space of time produced the “E” float, which
for ease in manipulation by untrained operators and volume of smoke
produced was probably unsurpassed by any subsequent device, and on the
score of cheapness it undoubtedly held the field.

This store, which was in reality a triumph of pyrotechnic design, was
in appearance so simple as to mislead some at least to whom greater
insight might have been credited as to the ingenuity of its design.
Counsel at a sitting of the Royal Commission on Awards to Inventors,
described the float as “half-a-dozen or so drain rockets in a box.” A
remark which might be considered as accurate as to describe a clock as
some pieces of metal in a box, were it not for the fact that the box
in question contained no drain rockets, or anything resembling them
more closely than one firework resembles another designed for quite a
different purpose.

[Illustration: Smoke Float in Action.]

The requirements to be met were as follows: The apparatus was to be
used by men whom by nature of their employment it was impossible to
train individually, therefore its ignition must be simple and at
the same time certain and quick in action, and carried on the float
itself; a chamber had to be provided in which to as it were accumulate
the smoke generated, which chamber had of necessity to have holes
through which the smoke could issue. As the float had to be dropped
after ignition from the deck of the vessel into the sea, and would
consequently be submerged for a short time, these holes must be in some
way sealed until the float rose to the surface. The pyrotechnic
compositions which produce the greatest volume of smoke were found to
take some considerable time to attain their maximum of production,
and separate units had to be included which would develop almost
instantaneously a big mass of smoke, pending the generation of the main
supply.

In addition, the float must be so constructed as to remain efficient
when stored on the deck of a merchant vessel in all weathers and
conditions.

Two hundred thousand of these floats were issued during the war.

The subject of smoke is one which naturally attracts the attention of
the pyrotechnist, although in what might be called a negative direction.

For display work the elimination of smoke is obviously of greater
importance than its production, but inquiry into the one of necessity
leads to a knowledge of the other.

In some few cases the smoke generated is of value in adding to the
effect of the burning composition; the most noticeable case of this is
the use of coloured fire as flares, that is to say, burnt in masses
for the illumination of trees and other natural features. Some years
ago Messrs. C. T. Brock & Co. spent considerable time in eliminating
as far as possible the smoke from coloured fire, when it was found
that without the smoke the result was very poor. It was the reflection
of the colour on the smoke upon which the illumination depended for
its effect. This, however, is hardly germane to our subject, but is
mentioned to indicate how largely the question of smoke enters into the
work of the modern pyrotechnist.

Commander Brock had, apart from his ordinary work, been engaged for
some months prior to the outbreak of war on the question of the
production of smoke for the Admiralty, and had also interested himself
in the subject for commercial purposes, such as insecticide and other
uses. He was therefore in a position, when the demand arose for smoke
both for naval and military use, to start research in the matter
considerably ahead of other inquirers, and to produce immediately
a smoke that would supply the needs for the time being until more
satisfactory means could be evolved.

The Royal Naval Experimental Station at Stratford, of which he was
in command and which he organised and brought into being, had many
activities besides smoke. But even the exacting work of controlling
its many activities was not sufficient for the Commander’s untiring
energy; the few moments he could snatch from his duties and the many he
stole from sleep were devoted to the invention and elaboration of war
devices. His greatest achievement was the Brock anti-Zeppelin bullet,
for which he and he alone is responsible, and which beyond any shadow
of doubt delivered this country from the terror of the Zeppelin raids.

His other inventions include many purely pyrotechnic smoke devices and
inventions connected with the production of smoke, such as igniters
which were used to start the action of smoke production, the Dover
flares of one million candle power each, used by the anti-submarine
patrol in the Straits of Dover, and burned to the extent of several
hundreds every night.

He was also responsible for several forms of stars for use in Very
pistol cartridges.

Captain Carpenter, V.C., in his splendid book, “The Blocking of
Zeebrugge,” writes as follows of his work in connection with that
operation:

  “It would be difficult for anybody to speak too highly of
  Wing-Commander Frank A. Brock. He was a rare personality. An
  inventive genius, than whom the country had no better, it was
  his brain that differentiated this blocking enterprise from all
  previous attempts in history in one most important particular. The
  difficulty of reaching the destination in the face of a strenuous
  opposition had hitherto brought failure, but he provided an
  antidote in the form of a satisfactory artificial fog designed to
  protect the blockships from the enemy’s guns during the critical
  period of approach. That in itself was a wonderful achievement, but
  his inventive mind was not satisfied therewith. To him we owed the
  special flares intended for turning darkness into light.

  “A special buoy was wanted—one that would automatically provide
  its own light on being thrown into the water. Brock made so little
  of the problem that he produced such a buoy, designed, constructed
  and ready for use in less than twenty-four hours. Special signal
  lights were required: Brock produced them. Flame projectors, far
  exceeding anything hitherto known, were mooted: Brock produced them
  also. No matter what our requirements were Brock was undefeated.
  With a highly scientific brain he possessed extraordinary knowledge
  of almost any subject. He had travelled much and could tell you
  all that was worth knowing of any country from Patagonia to
  Spitzbergen. He was no mean authority on old prints and books, was
  also a keen philatelist, and was blessed with a remarkable memory.
  Wherever he went he carried with him a pocket edition of the New
  Testament, which was his favourite possession; his knowledge of the
  contents was quite unique. And with it all he was a great shot and
  an all-round sportsman. His fine physique was well remembered by
  many a Rugby footballer from the days when he played in the pack
  of one of the leading club fifteens. His geniality and humour were
  hard to beat. But of all his qualities, optimism perhaps held first
  place. At times we, who were far from being pessimistic, thought
  his optimism excessive, but it was justified absolutely with regard
  to the success of the enterprise.”

The “Very” was a pre-war invention, patented in 1878; it was not
adopted into the Service until about ten years later. It consists of
a short-barrelled pistol of 1 inch calibre—or rather that was the
original size, a 1½ inch pattern was introduced during the war, and
subsequently a 1½ inch pattern with a longer barrel and shoulder piece.

The original cartridge was in effect a single star Roman candle, fired
by percussion. A small propelling charge drove out a single coloured
star, either red, white, green or blue. The star rose to a height of
about 300 feet. These were used purely for signalling purposes.

The war suggested another use of the “Very” pistol, that is for
illuminating purposes, and various illuminating stars were introduced,
both to light up upon reaching their objective with a range of two to
three hundred yards, and to hang suspended from a parachute, similar
to the old parachute light ball, but with many times the brilliance,
although considerably less in size.

The difficulty of identifying coloured stars in daylight suggested the
use of coloured smokes. These were successfully evolved by Major Wicks
and Captain Gray, an achievement of far greater difficulty than the
casual observer might think.

Apart from these synthetically prepared colours, the yellow smoke
natural to orpiment was much used in signal stars.

Later stars were suggested by Commander Brock, which ascended burning
white and at their height broke into two, and in a subsequent pattern
into three, stars of varying colours.

The rifle grenade, which was fired by a rod fixed to the base of the
grenade and running down the barrel of a rifle, being blown out by a
cartridge without a bullet, was also fitted up for signalling purposes.
Upon opening, a series of lights, arranged to code, were suspended from
a parachute.

Recognition and illuminating lights were constructed for use from
aeroplanes, and were ignited by dropping through a launching tube fixed
to the machine, which made contact and fired them electrically as they
passed through.

Landing lights and wing-tip lights, electrically ignited, were other
stores used in connection with aerial warfare.

Another was the incendiary bomb. Until the outbreak of war the
incendiary composition for use as stars in incendiary shells was of a
most primitive nature, and even during the war incendiary compositions
were used which were ridiculous in comparison with those produced later.

The construction also of some of the earlier efforts was quite as
absurd. Projectiles were devised in a thin paper case, intended to
be dropped from heights of many thousand feet, and ignite on impact,
whereas the impact produced by the velocity of a projectile after such
a fall was sufficient to scatter the case and its ingredients in all
directions.

It was the use of aluminium in pyrotechny which pointed the way to real
incendiary composition, composition which exceeds the temperature of
these primitive pitch and other elementary compositions by many times
more than the flame of a candle exceeds the temperature of ice.

Bombs containing thermit, and later on thermalloy (a composition which
set hard, and did away with the necessity of a case), were terrible
weapons, giving a temperature which has hardly been exceeded by other
means.

These compositions were almost identical with some of those containing
aluminium used in pyrotechny for a considerable time before the
war, but of course not for incendiary purposes. The intense heat is
naturally accompanied by brilliant light, which was of great value
to the pyrotechnists, the more so as aluminium compositions do not
deteriorate on being kept as do those containing magnesium, and
although the light is not quite so brilliant, and has less actinic
value, the fact that it is considerably cheaper, combined with its
keeping qualities, renders it a very satisfactory substitute for that
rather expensive metal, in very many cases at least.




                              CHAPTER XI

                      THE CIVIL USE OF FIREWORKS


The utility of fireworks and the number of purposes to which they have
been applied are far greater than most people imagine, both at sea,
where possibly their usefulness is most fully exploited, on land, and
since the war and its consequent developments of aeronautics, in the
air.

Firework signals at sea are used in almost endless variety for the
purpose of identifying vessels at night. Each shipping line has its own
signal or signals, which are fired on such occasions as when passing
Lloyd’s signal stations. These signals consist of hand lights, Roman
candles, rockets, or Coston lights. The last-mentioned is a small hand
light which is arranged to burn with either one colour or two or more
colours in succession. This signal is used by the majority of foreign
vessels. The signal used may be either lights burnt singly or together,
or a light or lights burnt in combination with Roman candles or
rockets. By making use of the various combinations a great number and
variety of signals have been arrived at: a few typical examples will
illustrate the kind of signals used.

The Zud-Amerika Lyn of Amsterdam burns a white light at stern, green
at bridge and blue at bow. The White Star have a green light at bow
and green at stern. W. Johnston and Co., a green light followed by a
Roman candle, throwing three red and three blue stars, followed by a
white light. The Aberdeen have a red light followed by a Roman candle,
throwing red, white and blue stars three times successively, shown from
aft. J. L. Burnham and Co., a blue light changing to white, then to
red, followed by a red star.

The Cunard Line, off the coast of Ireland, fire a blue light followed
by two golden star rockets. The Ulster Steamship Co. fire three
vertical lights, yellow, blue and red, followed by two Roman candles
fired together, each throwing two yellow, two blue and two red stars.

These examples will give some idea of the variety of signals used; they
are often followed by another signal, or rather have a suffix which
if fired has a particular meaning. For instance, a red light after
the signal may mean “All’s well,” or a green may signify a wish to
communicate. Some lines bring the whistle into the signal and combine
long and short blasts with pyrotechnic signals.

Besides the house signals there are some generally accepted signals
used by all vessels. A blue light is the signal for a pilot in all
waters, except those of the United States. It is curious, however, that
no universal pyrotechnic signal of distress has yet been arranged,
although in 1889 Mr. F. Crundall endeavoured to get a standard distress
signal recognised by shipping throughout the world. This signal, which
consisted of a Roman candle surrounded at the mouth by four lights
which burnt simultaneously with it, was demonstrated before the Board
of Trade, and was distinguishable across the Channel at Dover, but was,
however, not universally adopted.

Another extensive field use of pyrotechnic signals at sea is in the
fishing industry. Lights and rockets are used to communicate between
vessels of the fishing fleets and with the carriers.

The use of such signals by the coastguard and the Lifeboat Institution
and at harbours and ports throughout the world is also very great.

Another pyrotechnic store of the greatest utility is the line-carrying
rocket, a device which has been responsible for the saving of thousands
of lives.

The credit for suggesting this use of the rocket appears to belong
to a Mr. Trengouse, of Cornwall. This was in 1807. The proposal did
not, however, make as much headway as it should have done, owing to
the fact that Capt. Manley had that year introduced a device with a
similar purpose, the line being carried by a shot fired from a mortar.
This idea had been previously worked out by a Sergt. Bell of the Royal
Artillery and by La Fère, a Frenchman, the two working independently.

The Manley apparatus was officially adopted, and stations established
at forty-five positions round the coast.

The rocket method was, however, revived in 1826 by a Mr. Dennett, of
Newport, Isle of Wight, and four stations were established on the
island for the use of rockets of his pattern. The advantages of the
rocket over the shot apparatus are obvious—the lightness and mobility
of the rocket trough as compared with a mortar, the fact that the
rocket traces its own flight, which can be seen and followed even at
night, not to mention greater simplicity in working. However, it was
not until 1855, when a rocket of greater range was invented by Col.
Boxer, of the Royal Laboratory, that the rocket as a line carrier came
into its own.

The Boxer rocket consisted actually of two rocket cases joined head to
tail, and so arranged that when the first case had burnt out it was
blown off, and the second gave renewed impetus. This rocket is still in
use at the Board of Trade rocket stations.

A further development of the line-carrying rocket which is making rapid
headway is a compact apparatus designed for use on the wrecked vessel
to carry a line to the shore.

This system has two great advantages, namely, the target is so much
greater when firing from the ship, consisting as it does of the whole
coast line, whereas the ship forms in comparison an insignificant mark
from the shore. Again, a vessel is generally wrecked on a lee shore,
so that in firing from the ship the rocket travels with the wind.

Both the Brock and Schermuley systems are designed for this purpose,
and there is little doubt that in a few years all vessels will carry
their own means of establishing communication with the shore.

As a further development of the line-carrying rocket, it is interesting
to note that Congreve, in association with Lieut. J. M. Colquhoun,
took out a patent for the use of the rocket as a harpoon in whale
fishing, which, if it proved satisfactory in use, must have been a
marked advance, especially as this was before the advent of the now
universally used harpoon gun.

Another pyrotechnic invention responsible for the saving of many lives
is the Hale’s Light apparatus. This apparatus is fitted to a lifebuoy,
which is arranged for launching from a vessel’s bridge; the act of
launching ignites a flare, enabling the person in the water to see the
buoy and the rescuing boat to pick them up.

The practical use to which fireworks have been put on land are many.
Probably that which comes most readily to the mind is the sound signal
or alarm. Many fire brigades whose members are volunteers and therefore
scattered use aerial maroons to warn and call them for duty. These
maroons became familiar to Londoners during the air raid period in the
late war.

The maroon has also been adopted for firing with a trip line as a
burglar alarm, or for protecting game preserves or similar purposes.

Another well-known pyrotechnic sound signal is the fog signal used
on the railways, which consists of a tinned iron envelope containing
a mixture of chlorate of potash and red phosphorus. It is secured in
position on the rail by two lead clips provided for the purpose, and
is fired by percussion on the impact of the engine wheel. Bird scarers,
consisting of a series of single crackers connected by a time fuse, and
so arranged as to fire at regular intervals, have been much used for
the protection of seed and crops.

The miner’s squib and chieza stick or fuse lighter are to all intents
port-fires for lighting the fuse in blasting operations in mines, their
form and composition being adapted to the particular circumstances of
their use.

[Illustration: Crystal Palace. From a photograph taken by the light
  of a magnesium shell.

  The crowd at “Brock’s Benefit” (64,000 persons present).]

The use of pyrotechnic compositions for photographic purposes is well
known; those in use at the present generally contain magnesium, which
has greater actinic value than any other firework composition.

Magnesium lights fitted up to fire with a trip line have been
successfully used for obtaining photographs of big game in their native
surroundings at night.

Smoke pyrotechnically produced has for several years been used for
the testing of drains, and recently successful experiments have been
carried out establishing the value of smoke as a protection for fruit
blossom against frost.

It has also been used as an insecticide for use against various kinds
of parasites; a poisonous smoke has been found of great use in the
dislodging and exterminating of rats.

Another agricultural use of pyrotechnic, or in this case perhaps more
correctly explosive composition, is the use of explosive cartridges for
ploughing; that is, cartridges are exploded at a certain depth in the
ground, the effect being to break up the subsoil. The explosive used is
a mild and cheap form of dynamite.

The use of rockets and other explosive fireworks for producing rain
has been much discussed recently. Many writers deny the possibility of
success by such means. There cannot be the slightest doubt, however,
that given clouds in the right condition and altitude it is quite
possible to cause rain. The writer has seen it done, not once but many
times; generally it must be admitted when the rain was not wanted.
Maroons fired in wide-mouthed mortars have been used on the Continent
for some years to break up hail clouds and bring them down in the form
of rain over the vineyards, where a hail storm is a serious calamity to
the wine grower.

The use of pyrotechnic signals in connection with aerial travel is
gradually increasing. The stores used are practically those evolved and
adopted during the great war, modified in some cases to suit peace time
requirements, but substantially they are those described in the chapter
on Military Pyrotechny.
