PREFACE.


TO THE BOYS AND GIRLS:--

In this book we shall wander together a little farther, by the seaside
and by the wayside. Sometimes we shall walk on the breezy hills;
sometimes in the low, marshy places, where ferns and rushes grow.

Sometimes we shall stroll along the wayside path, where the
wild-flowers and grasses are woven into a wreath.

Sometimes we shall go to the hard, white sand, where the ocean waves
roll to our feet, and bring us shells and curious treasure from the
sea. Again, we shall go down to the still ponds, where lilies float on
the water and dragon-flies swim in the air.

Wherever we go, let us keep our eyes open and our minds awake to the
lessons of Nature. Then we shall be able to learn what beauty and
wisdom lie hid, even in such humble things as flies and worms. We shall
find much to delight us in beetles; and be as happy as kings while we
search out the secrets of airy hunters and marvellous little fishes.

SEASIDE AND WAYSIDE.




LESSON I.

A LOOK AT AN ANT.


You have been told[1] that an insect is a living creature with a body
made in rings, and divided into three parts. Most insects have six
legs, four wings, and two feelers.

There is a great Order of insects which we shall call the hook-wing
family.

[Illustration: The Wasp.]

The wasp, the bee, the saw-fly, and ant belong to this family. They
are the chief of all the insects. They can do many strange and curious
things.

You will know insects of this great family by their wings. The front
wings are larger than the back ones. They fold back over them when at
rest.

In flight the upper wings hook fast to the lower.[2]

If you look carefully at some kinds of insects, you will soon think I
have told you what is not quite true. Why will you think that? You will
say to me, “The fly has two wings, and not four.” “The ant has no wings
at all.”

[Illustration: The Bee.]

Ah, but wait until you study about ants and flies, and see what you
will think then.

The mouth of all the hook-wing insects has two jaws for cutting or for
carrying things. The mouth is nearly as wide as the head.

Above the mouth are two knobs. These knobs are two big eyes, one on
each side of the head. Between the two big eyes they have some little
ones, on the top of the head.

You see insects are as well supplied with eyes as crabs are with legs.

The back part of the body of many insects is made fast to the middle
part by a small joint, or thread. That is because these insects need to
bend, or even double up, in some of their work.

[Illustration: The Fly.]

The Hook-wing Order is divided into two great kinds.

The insects of one kind carry a little saw. The others carry a sword.
The sword is a sting. The saw is to cut up leaves and wood to make nice
soft nests or houses for the eggs. The sword is to fight with, or to
kill things for food. Among the saw-carriers is the fine, long fly,
called a saw-fly. Bees, ants, wasps, and others carry the sting.

Get one of these insects, and you will see all the parts of which I
have told you. Let us first take an ant to look at.

The head of an ant seems very large for its body, and the eyes seem
very large for the head. They look as if they would be heavy for the
little ant to carry.

On the under part of the body which is next the head are set the six
legs. These legs and the feet have joints.

[Illustration: The Ant.]

On the upper side of this same second part of the body are set the
wings. There are four wings, two large and two small ones. The upper
pair are larger than the lower ones.

The third or back part of an ant’s body is made of six rings. On the
tip or pointed end of this hind part is the sting.

Now I hear you cry out, “O, my ant has no wings!” Well, let me tell you
a secret. The wings of your ant have been cut off, or unhooked, as you
shall hear by and by.

There are many families of ants. Each has its own name and its own
ways. All ants are very wise in their actions. I shall tell you
many strange things about them. Ants have always been called “the
wise insects.” Would you not like to learn about their homes, their
children, and their way of life?

Before you study the ants in any book, I wish you would go out into
your garden or into the fields. Find an ant-hill, and sit or lie by it
for an hour or so. Take some sugar or bits of cake to feed the ants.
Find out for yourselves all that you can about them. Facts that you
learn in this way will be worth very much to you. Be careful and do not
disturb the hill or alarm the ants.

LESSON II.

THE LIFE OF AN ANT.


In ant-hills we find drone ants, queen ants, and worker ants. The drone
ants have no sting and do no work. Their bodies are longer and more
slim than those of queens. The drone ants have wings.

The queen ants also have wings. They have stings, and their bodies are
round and dark.

The workers are smaller than queens and drones. They are also darker,
and have no wings and no stings. Workers are of two sizes, large and
small. They are the builders, nurses, soldiers, and servants of the
others.

[Illustration: A House in a Hill.]

In an ant-hill there may be many queens at one time. Often the
ant-queens work. They are both mothers and queens. They will also act
as soldiers. The queen ant is not like the queen bee, who will allow
no other queen to live near her. I think mother ant a better term than
queen ant.

The word “queen” may make you think that this ant rules the rest. That
is not so. Ants have no leader and no ruler. Each ant seems to act as
it pleases.

The chief work of the queen ant is to lay eggs. In a short time, out of
each egg comes a lively, hungry, little baby ant. It is called a larva.
A larva is like a small white worm.

This little being needs to be washed, fed, kept warm and dry, and taken
into the air and sun. It must be cared for, very much as the baby in
your home is cared for.

The workers, who act as nurses, are very kind to the young larvæ.[3]
How do they wash these little things? They lick them all over, as the
cat licks the kitten. They use such care that they keep them nearly as
white as snow.

The nurses feed the baby ants four or five times each day. The nurses
prepare the food in their crops, to make it soft and fit for the little
ants.

The nurses stroke and smooth the larva baby. It seems as if they patted
and petted it. When the weather is cold, they keep the larvæ in-doors.
When it is warm and dry, they hurry to carry them up to the top of the
hill. They place them there to bask in the sun. If any rain comes, or
the hill is broken, the nurses run to carry the babies to a safe place.

When the larva is full grown, it spins around itself a little fine
net, which wraps it all up. When people see these white bundles in
the ant-hills, they call them “ant-eggs.” They are not eggs. They are
pupa-cases. In them the baby ants are getting ready to come out, with
legs and wings, as full-grown ants.

The pupa-cases are of several sizes. The largest ones are for queens
and drones. The next size holds large workers; the smallest cases hold
the smallest workers.

There are often in the hills very wee ants called dwarf ants. When you
study more about ants in other books, you can learn about the dwarfs.

After the ants have been in the little cases some time, they are ready
to come out. The nurse ants help them to get free.

Many hundreds come out of the cases. They crowd the old home so full
that they can scarcely find room to move about.

Then they see the light shine in at the little gates on the top of the
hill. They feel the warmth of the sun. They crawl out.

They push upon each other. The hill is not wide and high enough for so
many uncles and cousins and sisters and brothers. They act like great
crowds in the streets at a big parade, each one struggles for his own
place.

Young ants, like young people, wish to set up for themselves in new
homes. They spread their fine wings. Off they fly! Since there is not
room in the old hill they will build a new one.

They swarm as the bees do. As they rise high from the earth, they drift
off on the wind. Very many of them tire out and die, or are blown into
the water, and are drowned. A few live and settle on places fit for a
new ant-hill.

It is the mother or queen ant who chooses the new home. When she has
found the right place, what do you think she does? She takes off her
wings, as she does not care to fly any more.

The ant does not tear off her wings. She unhooks them, and lets them
fall away, and does not seem to miss them.


FOOTNOTES:

[3] When we mean only one we say _larva_; when we mean more than one we
say _larvæ_.




LESSON III.

THE ANT’S HOME.


Ants live in nests, made in the earth. We call them ant-hills, from the
shape of the part that is above ground. It is the queen ant who begins
to build the ant-hill.

[Illustration: The New Home.]

Like the mother wasp, the ant works on her nest until enough ants grow
up to do all the work. After that, like the queen bee, she does no
work. The work ants will not allow her to go from home.[4]

[Illustration: Sappers and Miners.]

When the ant finds a place for her home, how does she take off her
wings? They would be in her way while she worked. She presses the edge
of a wing upon the ground and so pushes it up and loosens the hook,
just as you unhook a dress. Then she begins to dig. She acts at first
much as your dog does when he digs after a chipmunk or a rabbit.

The ant lays her big head close to the ground. With her fore-feet she
digs up the soil, and tosses it back between her hind legs. She digs as
her cousin, Mrs. Wasp, digs.

[Illustration: Sappers and Miners.]

She keeps waving her little feelers, as if to find out the kind of
soil. Soon she has a hole deep enough to cover her body. It is too deep
for her to throw out the dirt with her feet. Now she uses her feet, and
her jaws, also, to dig with.

Where the soil is sandy, she takes it out, grain by grain. At first,
she must back out of her hole. Soon her hall-way is so wide that she
can turn about after she has backed a few steps.

Ants are very kind to each other in their work. If they push or tread
on each other in their haste, they never fight about it.

The ants know how to work and how to rest. After a little hard work
they stop, clean their bodies, take some food, and sleep.

As the making of the hall goes on, the ants bite off with their jaws
bits of dirt, and roll them up with their feet. They soon use the hind
part of the body to press and push the earth into a firm ball. These
balls are carried out and laid by the door. By degrees the balls form
the “ant-hill.”

When the hall is two or three inches long, they make a room. Then they
make more halls and more rooms. The rooms are for eggs, for larvæ, for
pupæ,[5] and for food.

People who have studied much about ants have had them build nests in
glass jars. Thus they have been able to see how they work.

To make a room, the ants often have to stand on their hind legs, and
bite the earth off, as they reach up their heads. Sometimes the ant
lies on its side, to clean off or smooth the side wall. They have been
seen at work, lying on their backs, as men do in mines.

The jaws of the ant have tiny teeth. In old work ants the teeth are
often quite worn off. The feet and jaws of the ant are well made for
digging. The feet have small hairs. By the aid of these the ants can
run up a piece of glass, or hang on a wall, as you would say, “upside
down.”

An ant-hill is made of very many little halls and rooms. Some open into
each other; some do not. The rooms are bedrooms, nurseries, pantries,
and dining rooms. Many of the rooms are shaped like a horseshoe. Some
are round.

The ants press and knead the floors and walls to make them hard and
smooth. Sometimes they line them with a sticky soil, like paste, to
keep the earth from falling in.

Some ants seem to make a kind of glue, or varnish, with which they line
their walls.


FOOTNOTES:

[4] For Lessons on Bees and Wasps, see First Book.

[5] _Pupa_ is used when we speak of one, _pupæ_ when we mean more than
one.




LESSON IV.

THE ANTS AT HOME.


We have taken a look at the ants and have seen how the hill is made.
Let us now see how the ants live in their hill-home.

When we go to visit them, we shall find ants running all about the
hill and in the halls. These are the work ants. Some seem to stand on
the hill to watch lest any danger may come near.

When the drone ants and the queens are young, the work ants let them go
out and fly. When they go out, the drones do not often come back. They
get lost or die.

The young queens come back, except those who go off to make new hills.
But when the young queen settles down in life, to her work of laying
eggs, the workers do not let her leave the hill any more.

How do they keep her in? If she has not taken off her pretty wings,
they take them off and throw them away! If she tries to walk off, a
worker picks her up in its jaws and carries her back.

The ants are kind to their queen. They feed her and pet her, and she
becomes very lazy. She does not even care to lay her eggs in a nice
clean place.

The idle queen drops her eggs anywhere. The kind worker ants pick them
up, and take them to a soft bedroom.

When there are too many young queens in one hill, they do not have a
war, as the bees do. The workers settle the trouble, by taking off the
wings of some of the young queens, and turning them into work ants.
This is done before the queens begin to lay eggs.

New-born ants and queens, who do not go out into the sunshine, are of a
light color. The other ants are dark.

In cold, wet weather the ants stay at home. If a rain comes up when
they are out, they hurry back. Early in the day, and late in the
afternoon, they all seem to be very busy. In the hot hours of the day
they stay in the hill and rest.

In very hot lands the ants stir about all winter. Such ants lay up
stores of food. You shall hear of them by and by. In cooler lands,
during winter, the ants are asleep, or, as we say, are torpid.

The young swarms usually go out in autumn. I have seen very large
swarms in the spring.

Ants like sugar and honey best of all food. They get honey from
flowers, and in other ways of which I will soon tell you. Some like
seeds which have a sweet taste. For this reason they eat some kinds of
grass-seeds, oats, apple-seeds, and such things.

Ants take their food by licking it. Their little rough tongues wear
away bits of the seed; they also suck up the oil and juice. They seem
to press the food with their jaws.

It has been found out that they know how to moisten their food and make
it soft. If you give them dry sugar or cake, they turn it into a kind
of paste or honey. Then it is easier to suck or drink it up.

If you put a nest of ants with plenty of earth into a large glass
jar, and put some food near by for the ants to eat, they may settle
down in the jar, to make a home. If you cover the outside of the jar
with thick, dark paper, the ants may build close to the glass. Then,
when you take off the paper, you will be able to see the halls and
storerooms.

You might put such a jar in a safe place out of doors. Then you would
be able to study the ants, as they roam around near by, or do their
work inside the jar.




LESSON V.

THE ANTS ON A TRIP.


The round hole in the ant-hill is called the gate. The ants can close
it with a bit of stone. Often there are two, three, or even more, gates
for one ant-hill. Once I saw a hill with six large gates.

Now I will tell you of a very queer ant-hill. It was made by big black
ants, in a little valley between two hills of sand.

Into this valley had blown a very large sheet of thick paper. It had
been around a ham and was very greasy. It had lain on the ground,
crumpled up, in sun, and snow, and rain, for a year.

By that time it was hard and stiff, and weeds had grown up about it.
One day, as I was going by, I saw ants running in and out of the folds
of the paper. I took a stick and turned the top fold open like a lid.

It was full of ants and of white pupa-cases. The ants, I think, liked
the folds of the paper for halls, and the larger wrinkles for rooms.
They had found out how to have a house without much work in making it.

When I opened this paper-hill, they ran in swarms to pick up the white
bundles. Poor things! They did not know where to go for safety. So I
laid the lid of their house back in its place, and soon they were quiet
again.

Now I will tell you how ants move from one house to another. One day
I saw by my garden path a line of ants moving all one way. They were
black ants.

They went two by two, or one and two, close to each other. Every one
had in its jaws a white bundle. I found that they all came from an
ant-hill. They came up out of the gate very fast, one by one, each with
its bundle.

About two or three inches from this line of ants I saw another line.
This line went _to_ the hill, not _from_ it. They went in good order.

They had no bundles when they went into the hill; when they came out,
each had a bundle, and joined the other line of ants.

[Illustration: On the March.]

I went along with the stream of ants that had the white bundles. I
found that they went to a new hill, about thirty feet from the old hill.

There they laid down their bundles, and went back to the old hill to
bring more. The bundles lay heaped in a ring all about the gate of the
new city.

Out of this gate ran other ants in haste. They caught up the bundles,
one by one, and carried them in. In about half an hour they were nearly
all taken in, and the ants brought no more. The moving was over.

[Illustration: On the March.]

With a long blade of grass, I gently took up a little bundle, I hid it
behind a stone, some six inches off. I took three bundles and hid them,
lifting them with the tip of the grass-blade.

When all the bundles left at the hill were carried in, the ants went
down the gates. But in a minute out came three or four ants. They ran
about wildly and searched the ground.

They went in circles and looked over the ground with much care. The
circles grew wider. At last one came up behind the stone and found the
bundles.

The ant picked up one bundle and ran. Then this ant met the other ants,
and, I think, told them the news. For at once the other ants ran up to
the stone, and each took up a bundle.

Then they all ran into the hill. Can ants count? That looked as if they
knew how many bundles they had. It also looked as if they knew that two
ants must go for two bundles.

A man who took bundles from a march in this way thinks that the ants
smell the hidden bundles. He says they will not search for them if you
hide them in the earth.




LESSON VI.

THE FARMER ANTS.


You have heard of the spider which makes a den in the ground. You know
that it puts a trap-door on its den, and plants ferns on the door to
hide it.[6]

The spider turns gardener in this way, and all his plants grow well.
There is an ant that has a farm, or garden.

This ant lives in warm lands. In this country they are found in Texas,
Florida, and in one or two other warm States.

These farmer ants raise grain to eat. The grain is a kind of grass with
a large seed. It is called by some “ant-rice.”

There is also a large ant which is fond of the seeds of the sunflower.
It is said that the ants plant the sunflowers in a ring around their
hill.

[Illustration: The Little Farmer.]

The ants have not been _seen_ to carry the seed and plant it. So we
may not be _quite_ sure that they do so. Perhaps they build where they
see young sunflower plants growing.

It is possible that the ant plants seeds of some kinds. You see there
are yet in the world many things left for you to find out. It will be
well for you to keep your eyes open.

The farmer ants do not live in a small hill that you could cover with
your hand. Their hill, or disk, is sometimes flat, and sometimes high.
It is often as large as a large room. It is in the shape of a circle.

[Illustration: An Ant’s Grain Field.]

In this circle all weeds and all kinds of grasses are cut down, except
the one kind which the ants like. The earth of the disk is kept clean
and smooth. Only the seeds of the ant-rice are left to grow.

When the ant-rice is ripe, the ants pick up the seeds as they fall,
and take them into the hill to their storerooms.

It is most likely that as the ants let this ant-rice, and nothing else,
grow on their hills, it sows itself by its fallen seed.

Still the ants are real farmers, as they keep their land clean, tend
and gather the crop, store it up, and eat it.

When the ant-rice is ripe, and the seeds have fallen, the ants cut down
the old stems, and take them away. The disk is then clean for the next
crop.

The ants will go a long way from their hill to find seeds to bring
home. They like to go where horses have fed, for there they find
scattered oats. In some lands they carry off much grain from the fields.

An ant in Florida climbs the stalk of the millet and cuts off the
seeds. When ants take seeds to their hill, they husk and clean them.
They throw bad seeds away.

The ants watch the seeds, and after rains carry them out to dry in the
sun. This is because if left wet, they would sprout and grow.

Some ants also cut the seed, so that it will not sprout.

The ants eat the seeds that they gather. They also feed their young
with them.

One ant in Florida rolls up into little balls the dust, or pollen,[7]
of pine cones, and stores that up to eat.

An ant in New Jersey cuts in pieces the little new pine trees, just as
they get above the ground, and carries them to its nest.

Did you ever see the ant which likes sunflower seeds to eat? It is a
large ant, and when it has climbed to the disk of the sunflower, it
pulls out one of the ripe seeds and carries it away.

When people keep a nest of ants in order to watch their ways, they feed
them with sugar, oats, apple-seeds, and wheat.

How does the ant eat the hard grain? Its tongue is like a file, or
something like that of the little shell-fish of which I told you.[8]
The ant can rasp, file, and press the grain, so it can get at and lick
up the oil and juice.

LESSON VII.

ANTS AND THEIR TRADES.


Since you know that bees, ants, and wasps[9] all belong to the same
great family of living creatures, you will not wonder that many of
their ways are alike.

You know there are wasps and bees that live alone. You have read how,
in the spring, Mrs. Social Wasp builds her home and raises a brood of
babies.

These, as soon as full-grown, begin to build more rooms and nurse the
next babies. Mrs. Ant does as Mrs. Wasp does.

Mrs. Ant begins a new hill, and as her children grow they help her. But
Mrs. Ant does not often begin her hill in the spring. She chooses the
early fall to begin work.

As the eggs change into working ants, Mrs. Ant gets plenty of help in
her work.

You have seen bees swarm, and hang in a bunch, or curtain. Ants also
cling together and form balls. But this is for warmth or safety. It is
called “snugging.” In some lands, in times of flood, ants form balls as
large as your play ball. Thus they can float on the water, and do not
drown.

As Mrs. Wasp makes paper, so Mrs. Ant can make a thin paper, for her
nest. But it is poor paper, not so good as Mrs. Wasp makes. Mrs. Wasp
is the chief of the paper-makers.

I told you how one Mrs. Bee cuts leaves to line her nest. So one Mrs.
Ant does. With cut leaves she lines a neat little nest. As the spider
makes a fine spun ball to put her babies in, there is an ant that makes
a woolly nest.

You have read of the Tower Spider, that builds a neat tower of sticks,
straw, and grass over her nest. There is an ant that thatches its hill
in much the same way.

There is a brown ant that is a mason. She makes her nest of little
balls of mud, laid up like bricks in a wall.

Then there is a carpenter ant, as there is a carpenter bee. These
carpenters cut their way into trees and logs. These ants hollow out the
inside of a tree, or beam, until it is ready to fall to pieces. In this
way they do much harm.

Besides their other trades, the ants know the trade of war. There are
soldier ants. Ants are mild and kind to each other while at work. But
they are brave, and have armies for war.

It is odd to see how much ant ways and ant soldiers are like human ways
and human soldiers.

The ants make war to get slaves, or servants. I will tell you more of
that in the next lesson. They also make war to get cows, as you will
hear by and by. They seem to have some other reasons for war.

When the ant army marches, it keeps in line and order. It seems to have
captains to rule and lead it. Scouts go before to seek out the way.

The ant-hill has some soldiers for sentries, to see that no danger
comes near. When a work ant gets into trouble, it will run to a soldier
for help.

The soldier ants do not appear to be cross. They have very large heads,
as if they wore big hats. Some of them have smooth heads, and some
hairy heads. They eat much and love to sleep.

The soldier ants do not do much work. They rouse up only for a battle.
In an ant-hill, the soldiers are larger, and often more in number, than
the other ants.

The workers are the smallest ants in a hill. There are fewer queens
than any other kind, except after most of the drone ants go off and
die. At that time there are very few drones.

In a battle, two ants will often cling to each other by their jaws,
until both die. The usual way in which an ant soldier kills a foe is by
cutting off the head.

Sometimes the battle ends without any killing. At other times the ants
are very fierce, and large numbers are cut to pieces.

When strange ants get into a hill, sometimes they are driven out;
sometimes they are killed; sometimes they are treated kindly.

I put a black ant into the gate of a city of brown ants. You should
have seen how they drove him out! He ran as if he were wild with fear.
Three or four brown ants came after him to the edge of their hill.

But though some strange ants are cast out so fiercely, there are two or
three kinds of beetles which go into ant-hills and live with the ants.
The ants do not harm them in any way. You shall hear about that when we
have some lessons about beetles.

LESSON VIII.

THE SLAVE ANTS.


[Illustration: The Parasol Ants.]

Now I must tell you about the slave ants and their owners. The chief
family of the slave-making ants is called “The Shining,” for its body
shines with a gloss like varnish.

The slave-making ants and their slaves are found in many parts of the
world. The masters are of a light or red color, with a bright gloss.
The slave ants are dark or black.

In nests where slaves are held the masters never do any work. They make
war and steal slaves, or slave babies. The slave ants do all the work.
If a war rises, they also fight for the hill and their owners.

The army of the slave makers will march to the hill of a tribe of ants
which they wish to seize for slaves. They carry off the pupa-cases,
where the little new ants are getting legs and wings.

These baby ants are taken to the hill of the owners and brought up with
their own young. No slave-ant eggs are laid in a hill, for the queens
lay all the eggs, and the queens are not slaves. The slaves are stolen
when they are eggs, or larvæ.

The owners seem to be very kind to their little slaves, and as the
slaves grow up and fill the hill they seem to do very much as they
please.

The slaves build new hills and take their owners to live in the new
home. If a mistress ant wishes to wander off her hill, her slaves drag
her back. If she does not wish to move to her new home, her slaves
carry her off, all the same.

The slave-owning ants walk about their hill in an idle way. If war
comes, then they fight bravely.

The owners do not build the house, nor nurse their babies, nor feed
themselves. Often they do not even clean their own bodies. They leave
all these duties to the slaves. The slaves feed their owners, and brush
and clean them, as a servant cleans his master’s coat. When the ants
are to make a move, the slaves pick up their masters, and carry them
away.

How can they do that? The ants carry all burdens in their jaws. The
slave and the master lock their jaws, the owner curls up the back of
her body, and the slave carries her off.

The grip of an ant’s jaw is very strong. She can carry things much
larger than her own body.

There is an ant which uses the pine needles for food. She carries the
bits of pine laid over her back much as a man carries a gun. There is a
little groove in this ant’s head, where the bits of pine rest. I have
seen very large hills covered with carefully cut bits of pine needles.
I think they have been sucked dry and then cast out.

There is an ant called the “parasol ant,” because it cuts off tiny bits
of leaf, and carries them along. Each ant holds a piece of leaf over
its head, like a parasol.

An army of this kind on the march looks very funny. These ants line
their nests with bits of leaf, to keep the dirt from falling in.

These parasol ants are very large. Their nests cover a large space. The
bits of leaf are cut about the size of a dime. The ants carry them in
their jaws, each piece by a little end left for a stem.

We have some parasol ants in this country, in Florida and Texas, and
there are many of them in South America.




LESSON IX.

WONDER ANTS.


You may perhaps read of what are called “Termites,” or White Ants. You
must not think that these are true ants, for they are not. They belong
to another Order of insects. They have four wings all of the same size.
But true ants have one pair of wings smaller than the other.

The white ants live in the ground and also in trees. They do much harm
by gnawing wood and trees. They swarm into houses, and eat the tables
and chairs and such things. They eat all kinds of food. They are much
like real ants in their ways. There are many of them in our country.

Now you must hear about the ants that keep cows. I have told you that
ants like honey. They take all their food by lapping and sucking it.
They suck honey from flowers.

If you look at the plants in the garden or house, you may see on the
leaves some very small green things, that seem to eat the leaves. Your
mother will tell you these are “plant lice,” and that they spoil her
plants.

The name of this little insect is Aphis. That is a very pretty name.
The aphis is very small, and is often of the color of the leaf it feeds
on.

This wee thing can make honey in its body much as bees do. But the
aphis does not store up the honey; it drops it on the leaf as it feeds.
This is called “honey dew.”

The ants eat the honey dew from the leaves, and they know that it comes
from the aphis. They stroke and tap the aphis with their feelers, so
that more dew will be let fall.

Have you seen the milkmaid go from cow to cow, and fill her pail with
milk? So the ants go from one aphis to another, until they get all the
honey they want.

The ants can carry home this honey, and give it to other ants. The
nurse ants will carry it to the baby ants. The workers take it to the
queens, owners, and soldiers.

The aphis is called the “ant’s cow.” A hill of ants will seem to own a
herd of these wee green cows. They go to them on their leaf, and get
the honey. They know and claim their own cows. It is just like having a
drove of cows in pasture, as the farmer does.

You know that people often keep cows in stables and feed them there.
The ant has this way also. There is a kind of aphis that loves the
dark and feeds on roots. Some ants keep a herd of these, hidden in the
ground. They pet, stroke, and clean them to get their honey dew.

Ants have been seen to fight for days over a herd of aphis-cows.
One hill of ants had no cows, and they tried to steal the cows that
belonged to another hill. After four days the lady that watched them
got twenty cows, and gave them to the hill that had none. Then the war
ended.

The ants which got the new cows seemed very glad. They licked and
petted the cows, and put them in a safe place. They took honey from
them and fed the soldiers.

This seems just like a fairy tale. But it is quite true. All these
things can be seen if you look out for them. But you must be patient
and anxious to learn.

In warm summer days, when your mother tells you that it is too hot to
run about much, what will you do? Why not make a tent of an umbrella,
placed near an ant-hill, and watch these pretty and curious little
creatures?




LESSON X.

THE WAYS OF ANTS.


I have told you that ants like honey and sweets. They will also suck
the juices and soft parts of many other kinds of food. Some ants eat
nearly everything that can be eaten.

Almost all ants will eat other insects, and suck the eggs or pupæ of
other insects. This habit makes ants very useful. Certain worms and
bugs that destroy orange trees and cotton plants are killed by ants.

Ants also eat other insects that injure men. If a coat that has these
on it is laid near an ant-hill, in an hour or two the ants will have
made it quite clean.

You have seen a fly sit and clean her body and wings. She does this
by drawing her feet over her head and body. So you have seen the cat
clean her fur coat with her paws and tongue. The ant washes or brushes
herself in just such a way.

The ant is very neat and clean in her habits. She takes many naps in a
day, and after each nap she brushes herself. She brushes herself tidy
after work and after taking food.

The action of the ant in cleansing herself is much like that of the
cat. The ant has on her fore-leg a little comb, shaped like your thumb.
With this she strokes and combs all dust and dirt from her body.

If you watch an ant as she dresses herself, you will see that she draws
her fore-foot through her mouth. This is to clean the comb and to make
it moist, so that it will do its work well.

[Illustration: Queer Capers.]

The ant has also little brushes on her other feet; so you see there is
no reason why she should not keep herself very trim and tidy.

[Illustration: Queer Capers.]

Ants are very neat about their nests. They carry out all husks of grain
and seeds and all dead bodies. They carry these quite off their hill.

I knew of an ant’s nest that had been set on a post in water. It was
kept clean by the ants. They soon learned to drop all refuse over into
the water. That is as the sailor does, when he tidies his ship.

Ants bury their dead. When an ant dies, some of the other ants pick
up the body to carry it off and bury it. They do not like to put dead
bodies near their hill. The ants will carry the dead ones round and
round, till they find a good place for them.

A lady who spent much time in the study of ants said that the
slave-owning ants do not bury the slaves with the masters. They put the
dead slaves in one place and the owners in another.

Ants will now and then change their home. They leave an old hill and
make a new one. When they do this, if some of the ants do not seem
ready to leave the old hill, the others drag them off by force.

Most ants have very good eyes, and can see above ground and under
ground. But there is one kind of ant that is blind.

Ants can bite with their sharp jaws. They also have a sting. They
seldom use it if they are let alone. Some ants have quite a sharp
sting. The sting is on the hind part of the ant’s body. Their sting is
made in three parts. There is the sack for poison, the needle which
gives the prick, and the case to keep the needle or prickle in. This
needle, of a light color, is like a little thorn.

The ant seizes with its jaws the part which it wishes to sting. Then it
lifts its body up on the hind legs, and swings its sting part under,
so that it can drive the sting into the place held by the jaws. The
sting does not do much harm to people, but will no doubt kill ants and
other insects.

Ants make also a kind of juice called “ant acid.” They can throw this
about when the hill is disturbed. This acid must be pretty strong. It
will make a dog sneeze and rub his nose. The ant uses it to keep dogs,
mice, beetles, and such things, away from the ant-hill.

I have told you that some ants harm trees and plants by gnawing or
cutting them. It is only fair now to tell you that ants help plants
to grow. As they creep into flowers for honey, they carry about from
flower to flower the dust or pollen which makes new seeds grow. This
dust sticks to the ant’s body, and what is taken from one flower is
carried to another. Bees also carry pollen.

Thus, you see that the ants help the flowers, which in their turn give
food to the ants. But, of course, the ants do not know what they are
doing for the flowers.[10] Nor do the bees know that they help the
flowers. The bees and ants do not know that pollen sticks to them, to
be carried about.

These lessons about the ant contain only a few of the many things
that can be said of this insect. I hope you will like the ants well
enough to get other books about them, and study and watch the ants for
yourselves.

[10] See Lesson XIII.




LESSON XI.

MR. WORM AND HIS FAMILY.


One day I saw a boy making a hole in the ground, and he dug out a worm.

I said to the boy, “What can you tell me about worms?”

The boy said, “Worms are long, soft things, alike at both ends. If you
cut one in two, each end goes off, and makes a whole new worm. They
have no heads and no feet and no feelings, and are no good but for
fish-bait.”

The boy thought he knew all about worms. But really he knew very little
about them. All that he had told me was wrong.

Worms belong to the great class of ringed, or jointed, animals. These
creatures have bodies made in rings or joints.

Let us take a careful look at our humble friend, the earth-worm.

He is a long, round, soft, dark, slimy thing, and you say, “He is alike
at both ends.”

Is he? Let us see. His body is made of from one hundred to two hundred
rings. These rings are smaller toward the two ends of the body, which
are the head and tail.

[Illustration: Like and not Like.]

Each ring has on it tiny hooks, too small for you to see. These hooks
take the place of the jointed feet that his cousins have. The feet on
a caterpillar will show you about how these hooks would look, if you
could see them.

By these hooks the worm moves along, and digs his way in the ground.
Mr. Worm can hold so fast to his den or hole, that you have hard work
to pull him out.

Have you seen Mr. Robin brace his feet and tug with all his might, when
he pulls out a worm? The worm is holding fast by his hooks.

You see the hooks are Mr. Worm’s feet. Let us now look for his head.
You have five senses. You can hear, see, feel, smell, taste. The worm
can feel and taste. Some think he can smell some things. Some say that
he cannot see or hear. I think that he hears, but maybe what makes him
come up to look about is not hearing, but feeling a jar on the ground.

Why do we say he has a head, if he has no eyes nor ears nor nose? We
say he has a head because he has a mouth and a brain.

His mouth has two lips. The upper lip is larger than the under. He
has no teeth. In the back of his head, not far from his mouth, is his
brain, or nerve-centre.

The worm is the only jointed animal that has red blood. Mr. Worm is
dark-colored because his body is full of the earth which he swallows.

If you keep him out of the earth for a while, his skin will get pale
and clear. Then you can see his red blood run in two long veins. He
needs fresh air to keep this red blood pure. He dies very soon if he is
shut up in a close box or case.




LESSON XII.

MR. EARTH-WORM AT HOME.


I told you the earth-worm has two veins. One runs down his back, the
other runs along the under side of his body.

There are tiny holes, like pin pricks, in his body. These are for the
air to reach his blood, to keep it red and pure.

In his body poor Mr. Worm has something that no other creature has. He
has two bags or sacks for lime. This is in some way to help him with
his food.

Mr. Worm has no teeth with which to grind his food. He has inside his
body small bits of stone. These are as small as grains of sand. They
are instead of teeth to grind his food.

When you study birds you will find that, like Mr. Worm, they have no
teeth. They, too, carry little millstones inside their bodies.

The little bags of lime help to grind or change the worm’s food in some
way, not yet well known.

The soft body of the worm will stretch like India-rubber. It will hold
a great deal of food.

Now you see that Mr. Worm is _not_ alike at both ends. One end has the
head, the stomach, the parts that serve for a brain, and a heart.

The hooks begin at the fourth ring behind the head. Look at the worm
when he lifts his head, and you will see his mouth.

The tail end has very strong hooks with which to hold fast to his cell.
This tail end is also his trowel, or mould, a tool with which this
poor, ugly worm helps to build the world.

Ah! now I have told you a great thing, a strange thing. Is it true that
the feeble, useless worm helps to build the world? Where is that boy
who knew so much about worms?

But before you hear how the worm helps to build the world, let us go
back to what the boy said. He said, “If you cut the worm in two, each
end will go off and be a whole worm.”

That is not true of the worm. When the worm is cut in two, the parts do
not die at once. As there are hooks and rings on each part, they each
can move off.

It is thought that if the fore part is left safe, the cut can close up,
and the worm can still live. A new tail may grow upon the front part,
as Mr. Crab’s new claw or eye-peg grows.

The hind part cannot live and grow. It cannot get a new mouth or heart,
so it can take no food, and have no blood. It soon dries up and dies.

The boy told me that the worm “had no feelings.” A worm can feel. The
sense of touch is the best sense it has. Put your finger on its body,
and see it move and shrink.

If the worm can hear, the organs that serve for ears have not yet been
found. It crawls up as you come near, and pokes its head out of its
hole and wags it to and fro. It has felt the jar of your steps.

The worm cannot see. Creatures that live under ground have but little
use for eyes. Fishes that live in dark cave-rivers have no eyes. If the
worm moves from the light and hides from it, it is because it feels the
action of light on its skin. It does not see the light.

What does Mr. Worm eat? Some tell you that he eats dirt. It is true
that he fills his body full of earth. That is to carry it to the top
of the ground. Mr. Crab has claws and legs to bend into the shape of a
basket. Poor Mr. Worm has no arms, legs, or claws, so he must make a
basket of himself.

Suppose you should be sent for fruit, and turn yourself into a basket
in that way! Your mamma might find fault. She would not wish you to act
like a worm.

It is true that the worm may find a little food in the earth which he
swallows. But the chief food of the worm is dead leaves and stems of
plants. It does not care for fresh, live leaves and stems and roots.

The worm also likes meat,--fat, raw, or cooked. Worms will gnaw or suck
the bodies of dead worms. We say worms _gnaw_. As they have no teeth,
they do not really gnaw. They pinch off what they eat.

Worms like onions and cabbage best of all food. They need plenty of
water, and must live in damp places. They soon die if they are put into
water. They choke as a fish chokes if kept out in the air.

When the worm gets food into its mouth, the rings of its body begin to
move out and in. They look as if they were opening and shutting. By
this motion they press the food down into the body.

When the worm wants to move, it stretches out its body to its full
length. Then it takes hold of the earth with its hooks. Next it draws
up its body, and so moves on. This is a wave-like motion, you see.
Watch it, and you will see that it travels with a motion like waves.

If you wish to find worms to study, you must seek for them in early
morning or late in the evening. You will be likely to find them when
all the earth is moist with dew, or when it is raining. They avoid heat
and sun.

Worms hurry to the surface of the soil to enjoy the falling rain. When
there is a long, dry time, the worms go down deeper and deeper into
the earth. You cannot find them when you dig for them. They need to
keep down where the earth is moist, soft, and cool.




LESSON XIII.

MR. WORM AT WORK.


Worms are found in all parts of the world. I have told you that they
help to build the world, and make it fit for the home of man.

Man cannot live without food. He gets his food from the earth. The
worms help to prepare the earth to bring forth the food of man.

Oh, this is very strange, that humble and dirty worms can be a help to
man! Man is the highest of all animals. Worms are nearly the lowest.
And can worms help man?

Now let us see how this is done. The worms live under ground. They make
long, winding halls, like streets, some inches below the top soil.
These halls, or little tunnels, help to keep the earth loose, so that
the fine roots of the plants can grow well in it.

These tunnels also serve to help the air move more easily through the
soil. By their constant motion below the surface the worms till the
earth, as rakes, spades, or ploughs till it above.

All this is of great use, and people say, “Many worms, rich land.” Now
and then you will hear, on the other hand, that the worms have eaten up
the seed sown. Or, people say the worms have bitten off the roots of
the plants. Some say that the worms cut the vines below the soil.

You need not think the earth-worms did that. Not at all! The
earth-worms never behave so ill. The “worms” that people mean, when
they speak of this harm done, are the grubs or larvæ of some insects,
as of the daddy-long-legs and others.

These grubs and cut-worms will eat living plants, but Mr. Worm likes
dead leaves and stems best. He wants his food made soft by decay.

Now we come to the chief work of the true earth-worms. When they make
their halls and houses, they fill their long bodies with the earth.
Some say it is their food.

Mr. Darwin says, “Oh, no! they fill their bodies with earth just to
get it out of their way.” If they get any food from the dirt it is not
much. They turn themselves into baskets to carry the dirt out from
their houses.

The worms work, work, work all the time, taking out earth, and carrying
it to the top of the ground.

There they pile it in heaps, called worm-casts. Each piece is the shape
of a small worm.

The earth takes this shape as the worm presses it out of its long,
soft body. Early in the day you can find these worm-casts over all the
garden paths. So you can after a rain. Go and look for them.

There are so many worms busy all the time that each year they bring up
tons of earth. This shows you the power that is in small, weak things.
In India there are worm-casts in heaps six inches high.

The worms make the earth fine and loose, by pinching it off with their
mouths. Then they bring this rich soil from below, and lay it on top,
and so on and on.

It is only some twenty years since this work of worms was known. At
first people said, “Oh, no, no! It cannot be that little, soft worms
could cover a great field, some inches deep, with new earth.” But it
was shown to be quite true.

Fields once stony and hard have become rich and fine. Things grow now
where once scarcely anything would grow. Ashes and gravel, once on top,
go two or three inches below.

All this is done by the busy worms. That is why I said that you could
call the tail end of the worm the tool with which he helps to build the
world.

Worms at work under ground have caused great walls and pavements to
sink, as the earth sinks over mines. Also, they have helped to bury
ruins and old cities, and to keep them safe hidden, until we found
them. We are glad when we learn of the old world days, from ruins which
the worms helped to hide.

Then, too, the worms help make the soil rich, by the dead leaves and
stems which they drag into their holes to decay. When the worms die,
their bodies also help to make the earth more fertile.




LESSON XIV.

MR. WORM’S COTTAGE BY THE SEA.


On the seashore you will find two or three kinds of worms. These are
called “Tube Worms,” from the shape of the houses which they build.
Some of them are called “Swimming Worms.”

The swimming worm is cousin to another family of creatures which look
like worms, but have many feet. They have a name which means “many
feet.”

You know that on most of the rings, in the body of the worm, are hairs
or hooks. You can see how easy it would be for these to become feet.

Each animal seems to have parts that are like some other animals,
and some new forms of its own. Thus, next the worm, with his rings
and hooks, comes another animal with rings and feet. Of all the ring
animals, Mr. Worm is the pattern, and after him comes his cousin, Mr.
Many-Feet.

While Mr. Many-Feet is like Mr. Worm, he is also like Mrs. Fly, and
seems to come between the two, a little related to both.

Now let us look at the seaside worms. Here we find some worms that have
eyes. We also find some that have little hard teeth, set in a ring
inside their mouths. There are some that have fine plumes, as gay as
any bird. These poor worms gleam like a rainbow.

[Illustration: Are they Cousins?]

New parts can grow on these worms as well as on the earth-worm, or
even better. Some say that they can even get a new head if the old one
is lost.

Some of these worms can bore into very hard things, as wood or stone.
Some of them shine like a fire. Ask some one to tell you of this kind
of light; it is like what we call Jack o’ Lantern.

Dig in the sea sand anywhere, and you will find worms, black, brown,
green, red, orange. They dig through sand and mud, and move very fast.

It is not yet known how these worms bore into stone and wood. Perhaps
it is by means of some acid stuff in their mouths. Perhaps it is by a
file, such as Mr. Drill has.[11]

If you look along the sea sand of some shores, you will find the
tube-homes of these sea worms. In their way of making a shell-home, and
making it larger as they grow, they are like the little shell-fish you
have read of.[12]

Most of these tube-homes are small, but some are very large. A
gentleman told me he had one with the bore or hole as large as his arm.

These worms by the sea serve as food for many fish and other creatures.
You know that nearly all fish like to eat worms, and that they are used
for bait. The boy who knew nothing else about worms knew they made good
bait.

He would have been full of wonder if I had told him that large worms
are used for food by men in some parts of the world. In this country we
do not make use of such food.

LESSON XV.

MR. WORM AT HOME.


Baby worms are just like the parent worms, only smaller, and with not
so many rings. As they grow, they get more rings by the dividing of the
last one.

In some kinds of soil the wee worms are born in a little hard skin bag.
This keeps them from harm, until they get strong enough to take care of
themselves.

Mr. Worm’s home is like a row of long halls. These halls are lined with
a kind of glue from the worm’s body. This glue makes the walls firm.

The halls are not deep under ground. If the weather is very cold, or
very dry, the worms dig down deeper. Worms dislike cold or drought.
They enjoy warmth. They also like water, and wet soil.

When winter comes the worms plug up the doors of their houses. This is
done by dragging into the doorway a plant stem that will fit and fill
it.

The worms carry into their homes leaves and stalks to eat. They bring
out, and throw away, things which they do not like. Worms show much
sense in the way in which they carry things in and out of their holes.
If a stem will not go in, they turn it over, and try it in some other
way.

[Illustration: Mr. Worm at Home.]

Worms usually come out of their holes at night or in wet weather. If
they go far from their house, they cannot find their way back. Then
they make a new hole. Each worm lives alone.

Often in the evening or early morning, or during rain, you will see
worms near their houses. You may find them with their heads just put
out of their doors. You will see the worm casts in early day or after
rain. It is then the worms dare to come out. Sun and heat dry worms up
very fast, and so kill them.

[Illustration: Mr. Worm leaving Home.]

The birds know all these ways of the worms. Watch a robin or a
bluebird. He searches for his food at sunrise, or after sunset, or
while it rains.

Now his keen eyes see the worm at his door! In goes his sharp bill! He
pulls like a good fellow! He is hungry. He wants his breakfast. The
worm holds fast by his hooks. The bird braces his feet and his tail,
and tugs hard. Out comes the worm to feed Mr. Bird.[13]

The bird shows great skill in the way he pulls the worm out of the
hole. He does not break off even one little bit of his soft body. No
boy could get him out in that way.

Some say that the worm lies by his door at sunrise for warmth. I do
not think that is so. I think what he likes is the fresh dew. He loves
dampness. He fears cold, but he also dies of heat.

Any worm will die in one day in dry air, but some kinds of worms will
live for weeks quite down under water. He needs an even, moist warmth.
His home must not be hot, nor cold, nor dry.

Little young worms know how to dig houses, make worm-casts, carry out
the soil, find food, and plug up the door of their houses. They know at
once all that old worms do. But then worm houses do not require as much
skill as bee or wasp houses.

The seaside worms make the prettiest houses. On shells, stone, wood, or
wound alone in a lump, you will find their tubes. They are white and as
hard as shell. Inside they are pink or blue.

These tubes curve and twist about, as the worm went that built them.
Some are very pretty. There is a soft kind of tube made of sand and
bits of shell, stone, and weed. The sand and weed are held together by
a kind of glue. The worm makes this glue in its mouth.

I have some tubes very clear and white. You can see the lines where the
worm went when he built them, ring by ring. Some of these tubes are so
small you can just run a fine needle into them. Some are as large as a
straw, and some as large as a fine fat earth-worm.

Now you see how much is to be learned, even of such a small humble
thing as a worm. Think how much even such a weak creature can do!

There is much more to be found out about worms, which I hope you will
be glad to learn for yourselves.

LESSON XVI.

A LOOK AT A HOUSE-FLY.


Look at a worm crawling about on the earth. Then look at a fly with
blue or green body and thin wings. See how it whirls in the air! You
will say, “These two are not at all alike.”

Yet there is one time in a fly’s life when it is very like a worm.

For this reason many wise people set flies and worms next to each other
when they study them.

You know, as soon as you look at a fly, that it is an insect.

You have learned that an insect has wings, six legs, a body in three
parts, and a pair of feelers like horns.

Insects breathe through all the body, and not by lungs as you do. They
have a row of holes in each side to breathe through.

The life of an insect passes through three states. These are the egg,
the grub or worm, and the pupa. When it is in the pupa it gets legs and
wings. The word “pupa” means _baby_ or _doll_.

There are some kinds of insects that vary in some of these points. The
fly is one that varies from this rule.

If you look at a fly, you will see that it has two wings, not four. It
is not one of the hook-wings.

Many insects can fold their wings. The fly cannot fold its wings; it
lays them back over its body.

Let us first look at a fly when it is most like an earth-worm. The fly
comes, in the first place, from a tiny egg laid by the mother fly.

When the egg opens, the baby fly is not like a fly, but like a little
earth-worm, both in its looks and in the way in which it is made. It
is a small white worm with rings, and on the rings are hooks.

If you wish to watch this change, lay a bit of meat in the sun on a hot
day. Soon flies will lay eggs on it.

The next day these eggs will be turned to grubs, which grow very fast.
The fly’s eggs are small and white, and are put upon the meat as if
they had been planted on one end.

The worm of the fly has a pair of jaws like hooks. It has two little
dots which will become eyes when it has grown to a fly. In the hooked
jaws and these eye-points it is not like an earth-worm.

The fly grub eats and grows. Then its skin gets tough and hard, and
forms a little case like a barrel. This shuts the worm in it, as in a
coffin. Now the baby fly seems to be dead.

But it is not dead. It is turning into a creature that has wings and
legs, and can fly and walk.

As the fly lies in its case, first the legs and then the wings grow. It
gets a head with mouth, eyes, and a trunk or tube, and from a poor worm
it turns to a wonder, as you will see.

But in its little coffin it is shut close, and its legs and wings are
all bent up. In a few days the change is made. Now it is ready to come
out.

It moves, and pulls, and gets free from the hard case. Then it strikes
the end of the case with its head time after time. At last it breaks
the case open, and out comes the fly!

Then it stands in the air, and in the sun if it can, and shakes itself.
It is cold and weak; but the air dries its wings and blows out the
wrinkles.

In a very few minutes the fly is strong and gay.

Then it spreads its wings and sails off to enjoy its life, and to look
for something good to eat.




LESSON XVII.

HOW TO LOOK AT A FLY.


Do you think a fly is a very small and common thing? Is it not worth
looking at? Let us see about that.

First, here is its head with two great eyes. We will soon look at the
eyes. Then you will see how curious they are.

There are, besides the big eyes, three little eyes. These are set on
the top of the head. Then, too, on the front of the head we find a
trunk or tube. And here is a pair of feelers. Inside the head is the
brain, very much like a worm’s brain. It is only a tiny white dot.

Next behind the head is the chest. The head has the shape of half of
an egg laid sidewise. The chest is nearly square. It is made of three
rings.

On the first ring is a pair of legs. On the next ring is a pair of legs
and a pair of wings. The fly has only one pair of wings.

On the last ring is a pair of legs. And near these legs are two little
clubs covered with fine hair. It is by means of these clubs that the
fly can halt or balance on the wing. They help the fly as the second
pair of wings helps other insects.

[Illustration: On the Wing.]

The third part of a fly’s body is the largest. It is egg-shaped, and
joins the chest by the thick end. This part also is made of rings.

Now let us look at the head of a fly. The feelers are like two long,
fine plumes made in joints. Most people think these feelers are made to
touch with. Their full, true use is not yet known.

You see, even in a fly there is much left for some of you to find out.

Some people think that flies smell and hear with these “feelers.” But
then they are so fine that a breath can jar them, and the fly might
_seem_ to hear when it only feels.

I know of something else like that. It is this. In some schools for the
deaf and dumb, the pupils are called to class or table by rapping on
the floor. The deaf do not hear the noise, but they feel the jar, and
come as if they could hear.

Let us look at the mouth of the fly. The lip of a fly runs out into a
long, slim tube or pipe. With this it sucks up its food.

At the end of this tube is a little flat plate. Close by it are two
sharp hairs. These are to prick the food, so that the tube can suck it
more easily.

When the fly is not eating, it can shut up this tube like a telescope,
to keep it safe. Did you ever see an elephant? Did you see his trunk?
The fly’s tube is his trunk. The elephant’s trunk is his long upper
lip. So is the fly’s trunk a long lip.

The chief parts to notice in a fly’s head are its eyes. These are so
large that they make up nearly all the head.

These big bright eyes look as if they had varnish on them. Now each of
these eyes is made up of a very great many small eyes. There are four
thousand of these small eyes.

[Illustration]

Between these two big eyes are three little single eyes, set in this
way--

Wise men have studied the eyes of flies for many years, and do not yet
know all about them.

The wings of a fly have a fine, thin, clear covering. This is held
out on a tiny frame, like a net-work. The fly moves these wings very
quickly. The motion of the wings helps to make the sound or _buzz_ of
the fly.

Now we come to the legs and feet of our fly. The leg is made in five
joints. The foot also has five joints. The last joint of the foot has
two claws and a little pad. These are covered with fine hairs.

The hairs catch on little points or rough edges. Thus the fly can walk,
as you would say, “upside down,” and does not fall. Besides, the pad
and hairs act like a sucker. They suck air from under the foot. So they
hold the fly from falling as he runs up a pane of glass. All boys know
what a “sucker” is and how to make one.




LESSON XVIII.

MRS. FLY AND HER FOES.


I suppose you have heard your mother wish there were not so many flies.
The fact is, flies make us much trouble. Their noise tires and vexes
people. They lay eggs in and on the food, and so spoil it. They cover
our clean walls and glass with small black spots.

Will you wonder that there are so many flies when I tell you that one
fly can in one season be the mother of two million others!

Many insects die soon after laying eggs. Bees and wasps do not, nor do
flies. Bees and wasps take care of their eggs and their young, but the
fly mother does not.

Mrs. Fly has more than a hundred eggs to lay at once. It is quite plain
she could not take care of so many babies. She must let them all look
out for themselves.

Still Mrs. Fly shows much sense as to where she puts her eggs. She
finds a place where they will be likely to live and get food and grow.

If the place is too wet the baby flies would drown when they leave the
egg. If the place is too dry, they would wither up and die. Then, too,
they must have soft food.

[Illustration: A Tavern by the Way.]

The fly does not lay her eggs on a stone or a piece of wood. She lays
them in some kind of food.

The fly can live all summer if it has a fair chance. Cold kills flies.
A frosty day will kill them. Some few flies, like a few of the wasps,
hide, and live over winter in a torpid state, and in the spring they
come out to rear new swarms.

Birds, spiders, wasps, cats, dogs, and some other animals eat flies.
These creatures kill flies by millions. People kill flies with poison
and fly-traps. If so many were not killed, we should be overrun with
them.

In the South is a plant with a leaf like a jug. On the seam of this
leaf hang drops of honey. Its juice can make the flies drunk.[14]

Flies like this juice. But as soon as they get it they turn dizzy and
act just like drunken men. They fall into the jug-like space of the
leaf and soon die. One of these plants will kill many flies in one day.

Many of our best birds live on flies, and if our birds were all dead we
should have much greater trouble with the flies.

In the autumn you will see flies sitting about as if they feel dull and
ill. If you look carefully you will see that the back part of the body
is white. It seems to be covered with meal or mould.

Soon the fly dies. This white dust is a disease of the fly. It does
not curl up its legs when it dies from this cause. They are stiff and
spread out. The fly looks like a live fly. If you touch it, it crumbles
to dust.

All around such a dead fly you will see a ring of white mould. This is
perhaps a real mould, or tiny plant, that seizes on the body of the
fly. It uses up all the soft parts, and so kills it, leaving only the
dry shell.

There is another strange thing about this. The body of a fly that dies
in this way is rent or burst open. The fly looks as if this dust or
mould had grown large in the body and so torn it open.


FOOTNOTES:

[14] See Reader, Seaside and Wayside No. III., Lesson XIII.




LESSON XIX.

OF WHAT USE ARE FLIES?


How often people cry out, “Oh, I wish there were no flies! What is the
use of a fly?”

But all things that God has made have their uses. And all God’s works
are worthy of study.

You have learned that worms are of great use. Let us see if Mrs. Fly
does any good in the world.

Mrs. Fly is of great use to man. She helps keep him in health. Do you
think that very strange?

People say, “Oh, these _dirty_ flies!” And yet these “dirty flies” help
to keep the world clean!

Now you know that over all the world, great numbers of animals die each
minute, and many of their bodies lie on the ground and decay.

Such bodies in decay cause disease and death to men. In winter, and in
cold places, such things do not decay so fast, and so do not make these
bad odors.

But in hot days, if such dead things lie about, they will poison the
air. Soon we should all be ill.

The work of Mrs. Fly is to lay many eggs in these dead bodies. In a few
hours these eggs turn to grubs, and these grubs to little live worms,
which begin to eat as fast as they can.

Soon they leave only dry bones, which can do no harm. They change the
dead stuff into their own fat, live bodies.

You know that the crabs are among the street-cleaners of the sea. So
the flies are among the street-cleaners of the air and land.

Did you ever watch flies dart about, here and there, with a flight like
hawks? They are eating up small, evil things, too small for us to see.
But these are yet big enough to hurt us if we should get them into our
lungs.

Ask your teacher to tell you a little about your lungs.

In and about our homes many bits of things drop, and might decay and
mould. This would make the air foul. But the busy and greedy fly drinks
up all the soft part of these things.

So we see that what we call the dirty flies help to clean away much
dirt. It is true too, that flies carry poison on their feet and trunks
from place to place. In this way they do great harm.

The fly serves for food for many birds, and fish and frogs, and some
insects. Some of these things we use for our food. Others are full of
beauty, or are of use to us, each in its own way.

Thus, though the fly is often a trouble to us, we find it is not
without its uses. Look at one of these little creatures through a glass
that will magnify it. You will see that the poor insect has really much
beauty.

From what you have read in this lesson you must not think that all
foul smells kill, nor that things that have no bad smell are always
safe. There are some gases that have no odor at all, which yet are very
deadly.




LESSON XX.

A SWARM OF FLIES.


Have you heard people speak of swarms of flies? By a swarm of flies we
mean a great number of flies rather near together. By a swarm of bees
we mean a number of bees that live and work in one place. A swarm of
bees divides the work of its hive. It has one queen bee. She is the
mother and ruler of the rest.

But flies have no home where they live in common. They have no work.
They have no one mother or queen, for whom the rest work. Each mother
fly drops her eggs where it seems best to her. Then she goes off. She
leaves her children to grow as best they can.

I have said that the fly likes best to place her eggs on a piece of
fresh meat.

These eggs soon turn to worms or grubs, and so spoil the meat. To keep
the meat from the flies the cook puts a cover over it. The cover is
often made of wire net.

“Now,” says the cook, “I can keep away that dirty fly.”

But Mrs. Fly says, “Oh, can you, Mrs. Cook? We will see about that.”

So Mrs. Fly sits on top of the wire cover. She puts her little egg tube
through one of the fine holes in the net. She drops egg after egg from
the tube. The eggs fall right on the meat, just where Mrs. Fly wishes
them to be.

Then the cook cries out, “How _ever_ did that fly get to my meat?”

Is it not strange that Mrs. Fly knows that her egg tube is the right
size to go through the mesh of the wire net? How does she know that the
eggs will fall on the meat?

Flies do another queer thing. If many flies are in a room, and you
begin to chase them to kill them, they hide. They creep into holes and
cracks.

They hide in curtains. They go behind pictures. After the hunt is
over, out they come, one by one!

Flies also know how to sham death, “play dead,” you would say. If you
hit one and make it fall, it will lie very still, and seem to be dead.
Then, after a little, it softly spreads out its legs and its wings.
Then it shakes itself. A moment more, off it goes.

This fashion of making believe to be dead does not belong to flies
only. Nearly all insects, and many other animals, sham death. It is
worth while to watch and see how well they do it.

When a fly is killed other flies come to eat up its body. They put
their trunks or mouth tubes on the dead fly and begin to suck. Soon the
body is sucked dry of all its juice. It is only a dry shell.

I will tell you something that you can do with a dead fly. If it has
not been dead so long that it has grown too stiff you can make the
wings move. Hold it by the body. Gently tip up one wing. As you lift up
one wing the other will rise too. They move together. It is as if they
were set on a little spring.

It is as wrong to be cruel to flies as to larger creatures. If they are
to be killed, do it quickly, and give as little pain as possible. If we
do cruel acts, we make our hearts hard and bad.




LESSON XXI.

SOME QUEER FLIES.


Although flies are of use, they also do evil to men in many ways. It is
well to look at things on all sides.

The fly you have been reading about is the common house-fly. That fly,
with its noise, dirt, and spoiling of food by laying eggs in it, is bad
enough. But yet the house-fly makes the least trouble of any of its
kind.

There are many kinds of flies. To the family of flies belong gnats,
midges, mosquitoes, and the big daddy-long-legs with wings.

You know well how some of these things sting, you say “bite,” you. Mr.
Daddy-long-legs hurts the grass lands with his grubs, which spoil grass
roots and the shoots of plants.

There is a fly called a “gall-fly” because it bites trees, and lays
eggs in twigs. Then upon the twigs grow over the eggs round balls
called “galls,” and these injure the trees.

There is also the “bot-fly,” which lays its eggs on the hide of the
horse. The egg causes the skin of the horse to itch. He licks the
place, and the egg goes into his stomach.

The egg of the bot-fly is apt to make the horse sick. The grub eats
holes in the stomach of the horse. That makes the horse sick. The
farmer will say that his horse is sick with “bots.”

In Africa flies kill horses and oxen by biting them. The bite poisons
the cattle and causes fever.

Farmers will tell you of a very bad fly that spoils wheat and other
grain. It is called the “Hessian” fly.

Flies, as they flit from place to place, sometimes carry with them
the poison of disease, as of sores and ulcers. Thus they spread these
troubles among people.

But while I tell you of that, I must not fail to say that flies, as
they go to flowers for honey, carry the dust of the flowers from one to
another. This helps new flowers to grow.

There is a large and handsome bright green fly, very fine to look at,
which bites horses and worries them. It is called the “horse-fly.” In
some lands a small sand-fly causes sore eyes.

Flies have been on the earth about as long as men have, or a little
longer, and there are some dead flies worth a great deal of money.

How is that? These are flies in amber. Amber is clear, hard, and bright
yellow. It is used for jewelry. Sometimes we see a perfect fly, held in
a clear, light mass of amber.

How did it come there? The amber was once a soft gum and the fly lit on
it. It stuck fast, and the amber flowed over it and grew hard, and so
buried the fly in a clear, golden tomb. A piece of amber with a fly in
it will bring a high price.

The “Spanish fly” is a large blue-green beetle. It is very handsome,
and is most useful when it is dead. It is used in medicine. It makes
blisters on the skin.

Do you say, “Oh, blisters are very bad!” Yes, they cause pain. But even
pain can be of use in this world. The blister, though it pains us, is
of use. It cures what might be a worse pain.

This Spanish fly is not a fly at all. It is a beetle which has been
given a fly’s name. It is put here at the end of the lessons on flies,
because in the next lessons you are to read about beetles.




LESSON XXII.

IN ARMOR CLAD.


Go to the garden or to the house plants, and after a little search you
will find one of the wonders of the world.

You will find a small, horny, shining, red thing with black spots on
its back. “Why!” you say “that is only a lady-bug, or lady-bird. We
say a little rhyme to it.”

The rhyme is--

    “Lady-bird, lady-bird,
      Fly away home!
    Your house is on fire
      And your children will roam.”

Yes, it is one of the beetles, and every beetle is a wonder. Come,
study this wonder.

The winged insects are divided into two great classes, Eaters
and Drinkers. That is what their Latin names mean. Butterflies,
house-flies, bees, and others, are drinkers. That is, they get their
food by sucking it through a pipe or tube.

This tube is on the fore part of the head; it is really the upper lip
grown long and round.

The other great class, the Eaters, eat their food with their mouths.
Some suck or lick it; some use their jaws to crush and break their food.

Beetles belong to the class Eaters.

The beetles are covered with a hard, horny shell, like a case. In this
they are like the old-time soldiers, who wore armor from head to foot.

Beetles belong to the great family of the ring-made creatures. Take a
large, round beetle, with big jaws, feelers, and legs. Does he not look
much like Mr. Crab, who is also ring-made?

In the pictures in this lesson you see Mr. Crab and Mr. Beetle. This is
a large beetle that likes to live among the grasses and weeds near the
seashore. When he and Mr. Crab meet on the sand they may think they are
cousins.

[Illustration: Mr. Beetle.]

Now let us get a beetle and look at him closely. You will often find
dead beetles on your path or in the grass. You can take them to pieces
and compare them with what you read about them.

The first thing that you will notice in the beetle is the hard case
over the wing. The wing-cases look like little shells, and have a nice
hinge to hold them in their place.

These two wing-covers fit close to each other over the beetle’s back.
When he flies he lifts them away from the wings. When you take off
these covers you will see lying under the cases a pair of neatly folded
wings. These wings are made much as Mrs. Wasp’s are.

[Illustration: Mr. Crab.]

The cases are used for armor, not for flying. They are really a pair
of wings. The fine silken under-wings are the pair with which beetles
fly.

There are some beetles that do not have this second pair, and so cannot
fly. There are some that have the upper pair so short that they do not
half cover the body. Beetles which do not have the lower wings creep
from place to place.

Watch a beetle as he crawls on the ground. Now see him! When his back
flies open two bright-hued shells rise up. This crawling thing sweeps
into the air on a pair of wide thin wings!

The part of the beetle’s body that is under the wings has rings like
those of the wasp. The body is made in the three parts insects have.
The wings and six legs are fastened on what you would call the chest or
middle part.

The wings fastened on the upper or back part of the beetle’s chest fold
down over the hind part of the body. On the end of the hind part is
what is called “the egg-placer.” With that Mrs. Beetle lays her eggs in
safe places.

The legs and feet of the beetle are made in joints. They have hairs on
them. The legs are so made and set that they cannot spread out as far
as those of spiders, wasps, flies.

Now here is Mr. Beetle’s head. It has two jaws and two feelers, the
mouth, and the eyes. There is a little horn shield over the mouth. In
fact, the whole beetle is in a snug horn coat. We may call this coat a
suit of armor.

The eyes of the beetle are like those of the fly. Very many eyes are
set in what seem to be two big eyes. The beetle does not have three
single eyes on the top of his head. Sometimes he has two small simple
eyes at the back of his head.

The splendid colors of Mr. Beetle are on his horn coat. I caught a
beetle last night which had the under part of his breast covered with
close hairs, so that it looked like velvet. He seemed to have on a rich
brown velvet vest.




LESSON XXIII.

WHEN MR. BEETLE WAS YOUNG.


In the lessons about the Ant, Fly, Wasp, Bee, and others, you have
heard that the young insect makes three changes.

First it is a small white or light-colored egg; then a fat, greedy
larva; then a pupa.

The insects you have thus far heard of, pass through all these changes
in a short time. So do some of the young beetles. But there are beetles
which spend one, two, three, even more, years, as eggs and grubs.

The long part of the lives of these other insects comes after they get
their wings. The short part of a beetle’s life generally comes after he
is winged.

You will not care to hear about the beetle while he is only an egg. As
an egg he lies quiet where the mother beetle hid him. These eggs are
placed in earth or in water. Sometimes they are put into the bodies
of dead animals, or into holes in trees, or into fruit. Some kinds of
beetles choose one place, some another, for their eggs.

[Illustration: Beetle Larva before it has Wings.]

After a while the larva comes out. Sometime you may find a long, soft,
stupid white worm, with its body made in rings. It has two big eyes,
two jaws, no feet, or, perhaps, very small ones, never any wings. Would
you guess it was Mrs. Beetle’s child? By and by it will have strong
wings, long, strong legs, a horny body, and very often colors like a
rainbow.

But this which you call a “white worm” is the beetle larva after it is
born from the egg. Sometimes it has no eyes. It is always very greedy.
Beetle larvæ will eat almost anything but metals. They harm wood,
trees, fruit, flowers, meal, furs, clothes, by gnawing and eating these
things.

The larva of beetles looks like the larva of butterflies. It has no
wings. No larva ever has wings.

The change of getting wings must come when the larva has gone into the
pupa cradle. Often in this state it lies as if asleep or dead.

When it is a pupa it rests in a case or cradle shaped much like a hen’s
egg. There the pupa lies, its legs folded over the front of its body,
its wings packed by its side, its jaws and feelers laid on its breast.
It looks very much like a baby laid asleep in a bed. It is not pretty
like a dear baby. In fact, it is ugly to look at.

The larva could eat, walk, roll, or swim. The pupa in this little case
can do nothing but wait. The full-grown beetle can fly, swim, eat,
walk, and is often a thing of great beauty.

If you dig about the roots of plants or under stones, you will, no
doubt, find larva and pupa to look at. It is well to seek out these
things for yourselves. Handle them gently; these are living things.

In some books you may read of a state of the insect called the image
state. This name is given to the full-grown, perfect insect. It means
that it has reached the same form that its mother had, which laid the
egg. Larva means mask, and pupa means baby.




LESSON XXIV.

HOW TO LEARN ABOUT BEETLES.


No class of insects has been more studied and written about than
beetles. Why is this? They are not as wise as the ants. They do not
build homes and cities, as bees and wasps do. They make no honey and no
wax. They have not the many trades of that busy Mrs. Wasp.

There are a few beetles which make little mud cells, or balls of dirt
for their eggs, or weave little nests for the pupa. But their work is
poor and rude and not as fine as Mrs. Wasp can do.

No doubt the reason why beetles have had so much notice is, that there
are very many of them, of very many kinds. They live where we can often
see them. We can easily take them to pieces, to study their parts, for
their bodies are firm and strong.

The parts of their bodies are very curious. Beetles can be kept a long
time after they are dead. They will not spoil as soon as soft-bodied
insects.

After all, the chief reason of the notice taken of beetles is their
great beauty. It is a beauty of color and shape. Often the cases are
lined and dotted as if carved with great care.

Would you like to have some beetles to keep, to look at and show to
your friends? Let me tell you how to get them.

Have a sheet of thick pasteboard, to fasten them on. When you walk out,
carry with you a bottle with a wide mouth and a good cork. If this
bottle has broken laurel leaves in it, the beetles will die as soon as
you put them in.

Or, you can kill the beetles with a little ether. Or, you can take up
the beetle with a little forked stick, and plunge it into very hot or
boiling water.

“Oh,” you say, “that would be so cruel!” But the truth is, the beetle
dies the instant he is plunged into hot water. He has no time to feel
pain.

Why do these things kill beetles so quickly? Here, now, is a great
fact that you must know. The insects do not breathe through the mouth
or nose, as you do. They have no lungs. They breathe through pipes or
tubes, wound over all the body. These tubes are very fine, and too
small to be seen with the naked eye. They are held open by a little
stiff, spiral thread, like this:

[Illustration]

These tubes spread even to the legs and feet of the insect. They reach
the open air by many openings, or breath holes. Now, when you plunge
the beetle into hot water, ether, or laurel odor, all its tubes are
filled, and it dies at once. When your beetle is dead, set it on the
sheet of stiff paper.

Draw the legs, feelers, and jaws into place with a pin or toothpick.
Then fasten the beetle to the paper with a tiny drop of thick glue put
under the body. Or, you can put a fine needle or pin through the body.
Be very sure that your beetle is quite dead before you put the pin into
him.

If you take this way of saving beetles, you will soon have very many,
of all colors, sizes, and shapes. They will be brown, black, red,
green, golden. I can hardly tell you how pretty the beetles are!

Put some on the paper, with the wing-cases raised, and the flying-wings
drawn out from beneath. The under wings are larger than the upper. You
will wonder that the beetle can pack them in the cases.

The feelers of beetles take many forms. Some are like plumes, some are
like scales or leaves, some like clubs. Some are nearly round like
balls, some are cone-shaped, some plain and straight; some are bent
like a new moon.

A farmer or gardener will like your beetles better dead than alive. As
he will tell you, the beetles and their larvæ are very greedy things.
They often eat leaves and spoil crops and trees.




LESSON XXV.

THE ROSE BEETLE.


The chief family of the beetles is a large one. It is found in all
parts of the world. The beetles that belong to it are large, and often
of fine color and shape.

In old times the people of Egypt called one of this family the sacred
beetle. They kept it as an object of worship. They often wore a stone
or metal image of it, to keep themselves from harm.

Let us now study one of this family. It is called the Rose Beetle.
That is a very pretty name. The beetle itself is pretty. It chooses a
pretty home and dainty food.

Some call this the Golden Beetle, because of its color. It is a fine
large beetle, with a thick body, round at the tail part. The feelers
are short and club shaped. The body, head, legs, and wing-cases are a
rich golden green, with silver spots and lines.

This beetle does not hold the wing-cases apart when it flies. It tips
them only a little. The wide, thin wings come out from beneath them.

[Illustration: The Rose Beetle.]

The rose beetle is seen most in May and June. You will find it in the
garden, about the flowers. Its chief food is honey and flower petals.
Its mouth is not horny, but soft and skin-like.

The feelers have ten joints, and wave lightly as the beetle flies. It
likes the sunshine. When it flashes about in the light, it looks like a
piece of melted gold with green tints on it.

The rose beetle chooses for its home and food the brightest and largest
flowers. It digs deep into the hearts of the roses. It sucks the honey
and chews the petals.

When the mother rose beetle wishes to lay her eggs, she finds a place
at the foot of a tree. She goes down among the roots, where the wood is
old and soft. Then she puts her eggs between the bark and the wood.

[Illustration]

Sometimes she changes her whole plan, and puts her eggs into an ant’s
nest! The ants do not seem vexed at this.

The larva of the rose beetle is a fat, round, white thing, like a thick
worm. The head is round, and of a pale brown color. The thin skin has
hairs on it.

These larvæ move very slowly, and always rest upon one side. They have
strong jaws, and their feelers have five joints. A number of them live
together. They are dull and lazy, and always eating. They eat leaves
and soft wood.

While the weather is warm, the larvæ keep near the top of the soil.
When it is cold, they dig down, even one or two feet, and lie asleep
until spring comes again.

They live in this way for three years. Then they make a round or
egg-shaped ball. They make the ball of grains of earth, bits of dead
leaves, and grass. Or, they use the wood or sawdust they have cut up
with their jaws. They fasten all this stuff together with glue from
their mouths.

When the larvæ are shut up in this ball, they change very quickly. At
first the ball, or case, seems full of a milky fluid. Then the legs
and wings grow. After a few weeks the white worm has changed to a fine
beetle that looks like a jewel.

Some of these beetles are so fine that they are put into hoops of gold
for ear-rings and brooches. In the island of Manila ladies keep rose
beetles in tiny cages for pets!

There is a beetle much like the rose beetle. It is called the May or
June bug. These June bugs come in great numbers. They eat the leaves of
trees, and even kill trees in this way. They fly by night; and they
like to get into a room where a lamp is burning. They are a golden
brown color.

They blunder about, making a great buzz with their horny wings. They
hit their heads on walls and panes of glass. Some people are afraid of
them. That is foolish, for they can do no harm to them.

These June bugs hide all day in the shade. They do not like the sun. It
is no wonder there are so many of them, as each mother lays forty eggs.
The larvæ do much damage by eating plant roots.

Watch June beetles to see how they lift their wing-covers when about to
fly. Look well at the folding of the inner wings.

If you open a door or window on a warm night and set a light in the
room, you may soon catch very many pretty beetles which fly about to
feast on the sweet white flowers that open after dark.




LESSON XXVI.

PRINCES AND GIANTS.


Beetles vary much in size. Some are so small that you can hardly see
them as they creep among the grasses.

Others are so large that a child might fear them. He might think that
with their thick legs and claw-like feet and strong jaws they must
surely be able to hurt him. But beetles are quiet, mild things, and
seldom pinch or bite anybody.

[Illustration]

Why do these beetles have these strong coats like mail? To keep them
from harm. They live under stones, and among roots, and dig about in
the earth. Their horny bodies protect them.

Many more animals, than now do so, might eat the beetles if they had
not the horny coats to shield them.

Fish, birds, and other animals eat them and their grubs. Enough are
killed and eaten to prevent the world being too full of beetles.

Beetles have few weapons. I will tell you of one or two of them. Stag
beetles have very large, strong jaws, and can give a good pinch with
them.

[Illustration]

One family of beetles is called the “Oil family.” They have an oil in
them. They drop this from their legs when they are touched. This oil
has a bad smell. It can make a blister on the skin. Because of this
oil people let them alone, and perhaps small animals do the same.

There is a beetle that carries a gun! This is like a gun with several
barrels, for it can be fired three or four times without being
reloaded! Oh, how can that be?

Near the tail of the gun beetle is a little sack or bag full of fluid.
When an enemy comes near him, Mr. Beetle, as he runs, throws off a drop
of this fluid. The fluid flies out of the bag with a little bang. It
sounds like the report of a tiny gun, and makes a kind of mist or blue
smoke.

Three or four of these shots follow each other. This beetle is a small
fellow. Big beetles like to chase him. When the wee gun goes off in the
big beetle’s face, the big beetle backs away. Then he folds down his
feelers and stands still. He acts very much as a dog does when he drops
his tail between his legs and runs off!

These little gun-owning beetles live in damp places. Often a group
of them will hide under a stone. If you lift up the stone, the poor
beetles are in a great fright. They begin to fire off their guns like a
squad of soldiers.

Now after talking about these little beetles, let us talk of great
ones. I told you some beetles are very small, and some are very large.
One beetle is so big that it is called the Giant. Another is called
Goliath, from the huge giant whom King David slew. Others are called
Atlas and Hercules, from tales told, in old times, of giants.

The very large beetles live in hot lands and are scarce. Some have the
jaws large and curved like a crab’s claw. At first sight you might
think them crabs. Some of these odd ones are shown in the picture.

The colors of these great beetles are often very splendid. Some of them
have long horns on the front of their heads. Some of them have the hind
legs so large, and of such a queer shape, that they do not look like
beetles.

Some of these giant beetles have large teeth or knobs upon their jaws;
they need them to crush and break their food. These teeth are like the
knobs on Mr. Crab’s claw, which he uses for playing a tune. The beetle
can use his knobs to make music. Beetles are fond of their own tunes.
Often they make, for hours, a shrill hum, or buzz. They make this by
rubbing their wing-cases.

There is a great beetle in Brazil called the Prince of Beetles. He gets
this name from his size and beauty. Some of the princes have been sold
for two hundred dollars each.

When you walk in the field, you might carry a bottle with a wide
mouth. In this you can collect beetles to study. It may be very
pleasant to study them when you go home. But have something in the
bottle to kill them, for, shut up in a small space, and frightened,
they are likely to pull each other to pieces.




LESSON XXVII.

THE LITTLE SEXTON.


Once, when I was a little girl, I saw a dark beetle standing on its
hind pair of legs. It was holding its fore legs clasped over its head,
as you can hold up your hands.

An old man who was near said, “That is a holy bug, and shows what man
ought to do. It is saying its prayers. People call it the ‘praying
beetle.’”

I think the old man meant what he said, but of course the beetle was
neither holy nor praying. The queer way of standing was only one of the
odd ways of beetles. Now I will tell you of another.

Very often on the road you will see a beetle, or a pair of beetles,
rolling about a small ball like a marble. The ball is of dirt, or some
soft stuff, and is often larger than the beetle. But she rolls it with
ease, for she is very strong.

The beetle is not playing marbles nor base-ball. She is only doing her
work. She has been flying about, looking for a good place in which to
lay her eggs, and now she has gone to work with all her might.

She lays her egg in a morsel of the stuff of which she will make her
ball. When the larva comes from the egg, this ball will be its food
until it is strong enough to crawl about and seek food for itself. The
beetle moulds the soft stuff over the egg, like a pill. Then, as she
rolls it about, it grows larger, as your snowball grows when you roll
it about in the snow.

When the ball is large enough, Mrs. Beetle does not leave it in the
road for wheels to run over or feet to tread upon. She seeks a place
where the larva may be safe and feed well when it comes from the egg.

She shows much sense in the choice of a place. She drags the ball along
between her hind feet, or she pushes it with her fore feet or her hind
feet, or rolls it along toward the safe place which she has chosen. If
the ground is so rough that she cannot drag her ball, she carries it on
her head.

This Mrs. Beetle’s head is flat, and has some wee knobs upon it. These
knobs hold her load firmly in place as she carries it along. Did you
ever see a boy carry a box, pail, or bundle on his head?

Perhaps Mrs. Beetle finds that she cannot, without help, take her ball
to a good place. Then she flies off, and soon comes back with other
beetles of her own kind. They all help her until her ball is where she
wishes it to be. How does she tell them what she needs? Who knows that?
No one. I have seen four or five beetles at work on one ball.

When the ball is in the right spot, Mrs. Beetle digs a hole with her
jaws and horny fore legs. Then she rolls the ball in. She fills up the
hole with earth and presses it down flat.

This is not the only beetle that buries its eggs. There is another one,
called the Sexton Beetle. When it finds a dead bird, or mouse, or frog,
or other small animal, it sets to work to bury it. It digs a little
grave for it. This is why it is called a sexton.

This beetle begins to dig under the dead body. As it takes out the
earth, the dead thing sinks more and more. At last it is deep enough to
be covered, as a coffin is covered in a grave.

In this way this beetle helps to keep the earth and air clean. Is that
why it buries things? Oh, no! The reason the beetle does this is, it
wants to get a good place for its eggs.

These sexton beetles are black, with yellow bands. They are rather
large, and go in pairs. You might think these beetles and the one who
makes the ball would be dirty from their work, but they are not.

[Illustration: The Sexton Beetle.]

These beetles have a kind of oil over their bodies. This keeps any dirt
from sticking to them. So, though they work in dirty places, they are
always clean and bright.

These burying beetles have a keen scent. They can smell a dead body
even if it is a long way off. Let us watch Mr. and Mrs. Sexton Beetle
at work. Here is a dead mouse. Through the air come flying these two
beetles. Their wings hum as they come.

When they alight, Mr. Beetle goes briskly to his work, and Mrs. Beetle
stands looking on. Her work in this world is not to dig, but to lay
eggs. Before the work begins, they both make a good meal off the dead
mouse. All sexton beetles eat flesh.

Mr. Beetle works a while. Then he drops down as if very tired, and
sleeps. Then up he gets and ploughs furrow after furrow about the
mouse. Mr. Beetle uses his head for a plough. Now the dead body has
sunk out of sight. Mr. Beetle has put over it the earth he took out
from the grave which he made. He makes all the little grave smooth and
trim.

But what is this queer little fellow doing now? He has made a little
side door into the grave. He and Mrs. Beetle walk in. They have gone to
take another meal from the mouse.

When their dinner is over, Mrs. Beetle lays some eggs in the dead body.
She knows that when the larvæ come from the eggs, they will like to eat
the food which they will find all around them. After the eggs are laid,
Mr. and Mrs. Beetle come out into the air.

Mr. Beetle fills up the doorway. Then off the two fly to find other
things to bury.

The larva of the sexton beetle looks much like a beach flea or
sand-hopper.

Does the strength of beetles surprise you? They have strong, sharp
jaws. Once I found a fine grass-green beetle, with silver spots.
I wanted him for my card of beetles. I tied him in the hem of my
handkerchief to carry him home. The hem was double, but he ate a hole
through it; then away he went.

Once I shut up ten beetles in a box. I forgot them for two days. When I
opened the box, they were all dead. They had killed each other. The box
had in it only heads and legs and wings. The last beetle that had been
left had lost his legs and wings. He had won the battle, but died on
the field. Some other great captains have done the same.




LESSON XXVIII.

THE STORY OF THE STAG BEETLE.


Among the largest beetles that we have in this country are the Stag
Beetles. They get this name from the size of their jaws.

If you look at the picture, you will see that the great jaws look like
horns. If you should ever see the head of a stag or deer, you may
notice that this beetle’s jaws are very like the stag’s horns in shape.

[Illustration: The Stag Beetles.]

These jaws can give a very hard pinch in time of need. Still you need
not be afraid of the stag beetle; he will not hurt you.

The use of these great jaws is not yet fully known. You will see that
they have knobs on the inner edge.

Only Mr. Stag Beetle has these horns. Mrs. Stag Beetle has small jaws,
and her head is not so wide as her shoulders. Mr. Stag Beetle has a
very wide head. He needs a wide, strong head to hold up his big jaws.

If you will look at the picture of the beetle in Lesson XXII.,[15]
you will see that its feelers are like a plume of six feathers. These
feathers are so set that the beetle can fold them on each other into a
single club, as you can fold a fan. They are called scale-feelers.

[Illustration]

The stag beetle has also curious feelers. They are made in scales, but
he cannot close them into a club. The scales are set like the teeth of
a comb. He has comb-feelers. Perhaps they are of use to him in cleaning
his body and legs.

These stag beetles during the day crawl about on trees. They fly by
night. Their eggs are usually laid in the trunks of old oak-trees.

The larva of the stag beetle has six strong legs and a pair of strong
jaws for cutting leaves and wood. The bark, wood, leaves, and roots of
the oak and willow are its chief food.

This larva is very large, and lies with its body curled in a half ring.
If you look at it, you will see that it has nine round spots down its
side, on the rings of its body. It looks as if it wore a coat with big
buttons on the side.

Now let me tell you a new wonder. These buttons are the air-holes
through which this larva breathes. Come, let us hear the whole story of
the insect’s breathing.

You know you draw the air in through your nose and mouth, and this air
fills your lungs. You know also that the insect breathes through long,
fine tubes. They are kept open with a stiff thread, and wound over all
its body.

These tubes have openings for air to pass in and out. These can open
and close. In shape they are a little like the lid of a glass jar.
These are the holes that we see so clearly along the side of the body
of this larva. Both the larva and the pupa must breathe, or they cannot
live.

The larva of a stag beetle lives and grows for four or six years; then
it passes into the pupa state. When it is ready to change, it makes
a case for itself of the fine chips, the juice of which it has been
sucking. It binds this sort of coarse sawdust together with glue from
its mouth.

When the stag beetle finally comes from this pupa-case, he is a
fine-looking fellow. His head and chest are black, with tiny dots like
carving. His wing-cases are a deep chestnut.

There are some stag beetles that never get the large, strong horns. We
do not know why this is so. Mr. Stag Beetle with the horns fights with
and beats his cousins who have no horns.

Stag beetles are fond of fighting. They are like Mr. Crab in that. They
have duels with each other.

Mrs. Stag Beetle does not behave in this way. She looks on at the
fight, but takes no part in it. Her business is to lay eggs in safe
places. She has no time to fight. And then--she has no horns!

[15] See page 75.




LESSON XXIX.

MR. BEETLE SEEKS FOR A HOME.


I shall now tell you of a very odd beetle. If ever you find one of this
family, you will say, “This poor beetle has outgrown his coat!” You
will say that when you see how very short his wing-cases are.

But no! the beetle has not outgrown his coat. Insects do not grow after
they leave the pupa-case. Mr. Beetle and his coat are both of the same
size that they always were.

In fact, this beetle’s coat was cut short for him at the first. It is
the fashion in his family to wear short clothes! The flying-wings of
this beetle are large, but the wing-covers are very short. They do not
cover half the length of the body. Yet this beetle can fold up and tuck
his flying-wings under the short wing-cases.

[Illustration]

Most of the short-coated beetles are small. Some of them are an inch
long. They are very lively insects. They are very greedy little
creatures, too.

Some of these beetles eat only animal food. They are always busy
hunting for it. Others of them are fond of mushrooms. Some of them have
a bad smell. People do not care to touch them.

Since their hard shell coat is so short, it would be easy to hurt them.
No doubt they have this bad smell to keep away creatures that would eat
them. The smell keeps them from harm.

The “short-coats” do not all have a bad smell. Some beetles with long
coats have this foul odor. There are also beetles that smell like
roses, and like musk.

Some of the short-coated beetles curl the hind part of their body over.
The end is held up above their backs. If they had a long, hard coat,
they could not do that.

[Illustration: He seeks a Home.]

You have read about the termites, or white ants.[16] In Brazil people
may find one kind of the short-coat beetle living in the nests of the
termites.

These beetles that live with the termites are very strange animals. The
back part of their body is too large for the front part. It looks like
a great ball, and is turned up over the upper part of the back.

These are the only beetles that do not lay eggs and go off and leave
them. They keep their eggs in this large, round part of the body until
they hatch. Then the little larvæ come out alive.

Why do the ants allow these beetles to live with them? Perhaps it is
because they make no trouble and so the termites do not care one way or
the other. Perhaps, like the little Aphis,[17] this beetle has a way of
making honey; if so, it pays for its house-rent with honey!

There are other short-coat beetles which do not have these big, round
bodies. They lay their eggs like other beetles, yet they live in
ant-hills. Perhaps these beetles and their larvæ like to feed on the
husks and rubbish they may find in the ant-hill. The ants do not drive
them out.

The short-coat beetles are not the only ones that take lodgings.
Perhaps you may hear your mother say that “the moths have got into her
furs.” If she looks at the furs, she may find, not only moths, but
small beetles. They are having a fine time eating up the fur!

Such beetles destroy furs, skins, skin rugs, and stuffed animals. Their
greedy larvæ can make much havoc. These larvæ are like tiny black
worms. They are fond of ham, bacon, and lard.

One very large short-coat beetle is called the “coach-horse.” The larva
of this coach-horse beetle looks like the full-grown insect. It carries
its tail aloft, in the same way. It can run fast, and seeks its food
all day long.

These larvæ often hide under stones. In the winter they go deeper under
ground. They are fierce, and they eat animal food.

The baby lives only about three weeks in the pupa-case. This case is of
an odd shape, like a wedge, with a rounded top. It is of a shining gold
color, and has a plume or crown of hairs in front.

[17] See Lesson IX.




LESSON XXX.

THE LITTLE WATER-MEN.


You know of spiders that live on land. You also know of spiders that
run upon the water. There are also land-beetles and water-beetles.

The water-spiders have rafts, boats, skates, and diving-bells. They sit
and float on lily leaves. Their homes are cool and bright under the
clear, still waters.

There is also a happy race of beetles that have all these things. The
story of these beetles is like the story of a fairy prince, but it is a
true story.

[Illustration: A Happy Race.]

All living things are fitted for the places where they are to live. The
animals that live in cold lands have thick fur. Birds are made with
light bodies,[18] so that they can fly easily. The fish have scaly,
pointed, slippery bodies, so they can glide swiftly through the water.

So you must expect to find that the water-beetles are not quite like
the land-beetles. They have bodies made fit to live in their water-home.

If you place a water-beetle beside a land-beetle, you will see that the
parts of the water-beetle fit more closely than the land-beetle’s.
They join each other so as to form a smooth, water-tight case. When we
build a boat, is it not our first care to make it tight, so that it
will not leak?

Next you will see that the water-beetle’s body is longer, narrower, and
more pointed in front than the land-beetle’s. It is made so as to part
the water as it moves along. The water-beetle’s shape is more fish-like
than that of the land-beetle. When we build a boat, we do not make it
broad or square at both ends. We make the fore-part narrow and sharp,
to cleave the water as the fish does.

As the water-beetles will swim much and walk very little, their first
and second pairs of legs are small and feeble, but the hind legs are
wide and strong, and reach far back. They are used for swimming.

Mr. Swimming Crab has broad hind legs, used for oars or paddles. Mr.
Water-Beetle’s legs are made in much the same way, and have hairs or
bristles upon them.

Though the water-beetles are to walk but little, they are to fly much,
and so their wings are fine and large.

In fact, the water-beetle likes to fly. Very often he flies at night,
and he seems to delight in a clear moonlight. Then the water of his
pond spreads out like a sheet of silver, and the crickets chirp in the
grass. The air is moist and cool; it is sweet with the scent of flowers.

On such nights the water-beetles rise quite high into the air, and fly
here and there, as if full of joy. Then they turn, close their wings,
and drop into the water with a plash, like a stone.

When a number of these beetles drop with this quick plash, what do you
think happens? Why, the green frogs who sit on logs or rocks, with
their big eyes above the water, dive in a great fright. I wonder if the
beetles think it is fun to scare the frogs? The frogs give a loud croak
as they dive.

The larvæ of water-beetles live in the water, as their parents do. They
are very greedy, and hunt their food as if they were angry. They have
large jaws, shaped like a sickle. Their bodies are long and narrow, and
they have on each side of the head six tiny eyes.

With so many eyes, they can see all about them, so they keep out of
danger. They also see bugs which they wish to catch. Their straight,
narrow bodies dart through the water with such quick motion as Mr. Crab
has when he runs on the sand. They pounce on their prey, and their
curved jaws hold it fast.

Some of these great water-beetles have a sharp point, like a thorn, on
the under side of the breast. This is not of use to kill what they eat,
or to fight their enemies. The beetle seizes his prey with his jaws, or
with his fore feet. But if you try to hold him, then he draws his body
back, and drives this thorn into your hand.

Water-beetles have flat pads on their feet, as water-spiders do. The
hairs on these pads hold tiny bubbles of air.

When these beetles wish to fly, they do not rise straight out of the
water; they climb up the stem of some plant. Then, when they are high
enough to make a good start, they spread their lovely wings, and skim
away.

If you watch the ponds, you may see a water-beetle floating with his
head down, and the tip of his tail stuck out of the water. What does he
mean by that queer action?

He is getting air to breathe. Though he lives under the water, he
breathes air, and he is filling up his diving-bell; or, rather, he is
turning himself into a diving-bell. How does he do that? Let us see.

This beetle’s wing-covers are air-tight. The mouths of his
breathing-tubes open under the wing-covers. When he has used all the
fresh air he had, he wants some more. So he comes to the top of the
water, turns his head down, and spreads out his feet to balance
himself. Then, with a little jerk, he drives out any air that is yet
under his wing-covers.

Then he draws in fresh air, shuts his wing-covers up close, and goes
down with plenty of fresh, pure air to breathe.

I have known people who will shut themselves up in a room and breathe
the same air over and over again.[19] The beetle, you see, is more
sensible. He knows that if he is to keep his health and spirits, he
must have good, fresh, clean air to breathe. So he takes all this
trouble to get pure air.


FOOTNOTES:

[18] See Third Book.

[19] Let the teacher explain the evils of vitiated air.




LESSON XXXI.

WHIRLIGIG BEETLES.


There is a Mrs. Water-Beetle who has on the under side of her body two
little knobs for spinning silk. These are much like the silk-spinners
of Mrs. Spider.

As soon as this Mrs. Beetle has laid some eggs, she goes to work, like
a good mother, to keep her babies safe and warm. She spins a little
silk ball, or bag, for the eggs. This ball is water-tight. It is woven
so close that it does not leak. It is so light that it will float.

There are other beetles, and fish, and frogs in the water, that are
seeking food, and they might eat these eggs, but will not touch them
when in this tough silk ball. The balls are of a fine bright color,
like gold thread.

Another of the water-beetles makes a little silk bag, packs it full of
eggs, and glues it to the under side of a leaf of some water-plant.

You know that a fly has a little pair of wings, called alulets, below
its true wings. One of the beetles has such clubs or alulets. So you
see in one part they are somewhat like a spider, in another part
somewhat like a fly. And some things about them are like what a crab
has.

Among all animals you will find points of likeness between one creature
and another.

Did you ever see a whirligig beetle? He takes his name from the top,
or whirligig, because he spins round, and round, and round. Go to the
pond, and you will see some of these merry fellows. They act as if they
felt so happy that they could not keep still.

These whirligigs are of a fine bronze color. They use their hind
legs for oars, and their fore legs for rudders. They have their eyes
divided, so that each one seems to have a pair of eyes on each side of
its head; one half the eye looks up, and one looks down.

These are small beetles, and they whirl, whirl, whirl. Then they stand
still for a second. If you make a dart at them, and try to catch them,
you will find that it is not easy to do so.

These whirlers lay their eggs on leaves above water. The larvæ spin
silk pupa-cases which hang on leaves, or on stems, above the top of the
water.

These and other water-beetles live in ponds or very quiet streams, not
in swift water.

I hope the peep you have had at beetle-life will make you wish to study
it more. Study not so much in books, as out-of-doors for yourself.

Of what use are beetles? Wise people have not yet found out very much
about the use of beetles. Some of them, as you have read, devour or
bury spoiled things, that it would be bad to have lying about on the
ground. They help to keep the world clean.

Some of them eat insects that harm plants. Some of them make good food
for fish, birds, and other creatures. But very many of the beetles do
much harm to plants, clothes, and other valuable things. On the whole,
I fear that beetles are pretty rather than useful!




LESSON XXXII.

WHAT A FISHERMAN TOLD.


One day, on the sea-beach, I saw a man mending a net. He took from the
net two small things like shells. They clung to the meshes of the net.
They were white and hard. They looked like two or three shells put one
inside the other.

The fisherman said, “There are in the world more of these things than
there are leaves on the trees, I think.”

“Where do they grow, Mr. Fisherman?”

“It is easier,” said the fisherman, “to say where they do not grow,
unless I just say, they grow wherever there is sea-water. The pier
yonder, below high-water mark, is covered with hundreds of them. All
the rocks that we see bare at low tide are white with them. Every log
or stick that drifts on the sea has them on it. All the old shells on
the beach, and many new shells, have dozens fastened on them.

“I have seen an old King Crab crawl up the beach,” the fisherman said.
“He had his shell so coated with these things, that it seemed as if he
had two shells, one on top of the other. It was so heavy that he could
hardly walk.

“I have also seen them growing in the skins of whales, and sharks, and
other fish. I have sailed all around the world, and I have found these
things everywhere.”

“What do you call them, Mr. Fisherman?”

“Some call them Sea-Acorns, some Sea-Rose-Buds. These are pretty names;
but Barnacle is the right name.”

“Do you know, Mr. Fisherman, that they are cousins of the crabs?”

“I’ll never believe _that_,” said the fisherman. “They do not _look_
like crabs. When I was a boy, folks told me that out of these shells
came a little bird that grew into a goose. I saw a picture once, of
a tree all covered with big barnacles, and out of each one hung a
little bird’s head. Is that tale true? They were not quite like these
barnacles.”

“No, Mr. Fisherman, it is not at all true. No birds grow from
barnacles. That is an old-time fable.”

“Well,” said the fisherman, “once in the water I saw something hanging
out of the shell of a fellow like this. It opened and shut, and looked
a _little_ like a bird’s foot.”

“It was a foot, Mr. Fisherman, but not a bird’s foot. It was Mr.
Barnacle’s own foot, and as he has no hands, he uses his feet to catch
his dinner.”

“I know,” said the fisherman, “that horse-hairs in ponds will turn into
long worms. But I never did think these shells would turn into birds.”

“And horse-hairs will never turn into worms. Long, thin, black worms
in ponds look much like the hairs of a horse’s tail, so some people
think they must once have been horse-tail hairs. But it is not so.
Horse-hairs are always only horse-hairs, and worms all come from eggs
which were laid to bring out a worm.”

“It is a pity,” said the fisherman, “that when I was a boy in school my
books did not tell me of these things. It would have been nice to know
what I was looking at as I went about the world.”

Now let us study these barnacles of which our fisherman spoke. He told
us truly about their number and where they grow. He told us what he
knew because it was what he had seen.

There are two kinds of barnacles,--those that have stems, and those
that have no stems. The kind that has no stems is the kind you will see
oftener, though there are plenty of the other kind.

The stemless, or acorn barnacles, are placed flat upon whatever they
grow on. Try to pull one off a stone. You cannot do it while the animal
is alive. When the animal is dead or dying, you can move the shell from
what it grows upon. After the animal has been dead some time, the
shells drop from their places, and leave room for others to grow.

All barnacles do not fix themselves upon dead bodies, such as stones,
wood, or shells. Many of them fasten upon living animals, and are
carried about with them from place to place. Perhaps they enjoy travel!

In the North Sea many sharks have barnacles growing upon them. The stem
of the barnacle has little hollow hairs, and these enter into the flesh
of the shark and hold fast there. Others have been found keeping house
upon the whale’s skin, and yet others on the shells of turtles.

These barnacles which you find by the shore are small things, you can
hold several of them in your hand at once. Far down in the ocean lives
a huge giant barnacle, so big that some of you could hardly lift him.




LESSON XXXIII.

MR. BARNACLE AND HIS SON.


The Barnacle has a name which means hair or ringlet-footed. People
thought his little fine curled-up feet looked like small curls of hair.
His body is like a small bag or sac, with the six pairs of little
curly feet placed at one end. The body is made of rings as are the
bodies of insects. All the six pairs of legs are on the chest rings.
Each leg has two joints, and a little branch like a fine fringe. The
hard shelly cover of the barnacle is made of plates lapped together.
When they are closed they look something like buds on trees, or young
pine cones. When the fringes of the feet wave out between the edges
of the shell-plates, it looks as if the buds were about to open into
flower.

A barnacle is more like his far-off cousin Mr. Crab when he is little
than when he is grown up. Every grown-up barnacle must be firmly
fastened upon some other body. The barnacles are divided into two
classes, according to the way in which they are fastened upon objects:
1. Stem Barnacles, 2. Stemless Barnacles.

A stem barnacle has plates which form a three-cornered shell. It grows
fast to some object by a small stem which is soft, and can bend about
easily.

A stemless barnacle has a shell shaped like an acorn, or like a rosebud
with the top bitten off. Instead of a stem, it is held fast to the
object on which it grows by a thin plate of shell at its broad, or flat
end. This plate has a tiny hole in the centre.

When you first saw a barnacle, you would not think it was any relative
of Mr. Crab. When grown up it does not look at all like the Crab
Family. When crabs and barnacles are very young, they look more like
each other.

[Illustration: Old and Young Barnacles.]

Let us look at an acorn barnacle. The shell is in plates, as if two or
three shells were set one over another. The shell grows by added bits
of lime, as a conch shell does. The thin skin that lines it, and holds
it together, is shed, like Mr. Crab’s coat. Then the shell has room to
grow.

The shell is hard and white. It is lined with a very thin skin, which
often has a faint, pretty tint.

The stem barnacles have long, flesh-like stems which move and sway with
the motion of the water. They look much like a little, queer, pale plum
hung by a thick stem.

The end of the barnacle, which clings to the stone, log, shell, or fish
on which it has fastened itself, is the head end. The two feelers,
which all these animals have, are turned into two fine tubes, or pipes.
These feelers have little glands or sacs which make a strong cement.
Cement is like glue, but much more strong and stiff.

This cement fastens Mr. Barnacle to his place. So after he has settled
himself in life, he never wanders about any more.

Did Mr. Barnacle ever go abroad? Oh, yes! When he was young he swam
about the water-world, in a very brisk way. Let us hear about that.

Mr. Barnacle makes the same changes of life that an insect does. First
he is an egg, then a larva, then a pupa, and at last a steady old
barnacle. But the larva barnacle makes two or three changes of shape
before it turns into a pupa.

Barnacles grow fast. They change their coats often when they are young.

Here is an old acorn barnacle fast upon a stone. It is about as big as
the end of your little finger. It has some eggs which it packs into the
shape of a small leaf. It tucks this leaf of eggs into a fold of the
thin skin that lines the thick shell.

As the eggs get ready to hatch into larvæ, the old barnacle is also
growing, and making more shell. Soon it is ready to enlarge the outer
shell. So the inside skin cracks apart and falls off. By degrees some
barnacles become quite large as fresh shell grows from within.

[Illustration]

When the old inside skin falls off, the eggs are set free. Out of them
come the larvæ. The larvæ are active, hungry little fellows, who know
how to swim as soon as they are loose in the water.

The larva acts as if it liked to be free from the shell prison. It
darts about in the sea, and each day its shape changes. It has one eye,
a mouth, two feelers like horns, and six legs. It can swim, and can
walk over sea-weed.

Some parts of this gay little larva will one day turn into tubes to
make cement to hold it fast to a stone. Then it will be a stay-at-home
barnacle all the rest of its life long.

When the larva becomes a pupa, it drifts about until at last it is time
for it to stop travelling and keep still. Then it fixes itself by its
head to the place that will always be its home. All it has to do after
that, is to fish and eat. As it makes new shell, it will enlarge the
old shell. And it will have little eggs, packed in the shape of a wee
leaf between the skin and outer shell.

By and by Mr. Barnacle has a hard shell of many plates, his eye has
gone down near his stomach. Do you think he can see what he eats? His
legs are not used for walking, but to fish with; his mouth is near his
feet. The rest of his head has gone off with his feelers, to attend to
making cement and shell. What a queer creature he is!




LESSON XXXIV.

A FISHING PARTY.


Did you ever go fishing? Did you fish with a rod and line? Or, did you
sit on a pier and let your line drop into the water from your hand?
Or, did you go out with the boats and see the men throw a net into the
water?

There are many ways of fishing, and now I shall tell you of some queer
little fishers and their ways. Why did you want to catch fish? Oh, just
for fun!

My little fishers fish for food, and they eat their fish without any
cooking. Their fish are so small that you cannot see them without the
help of a glass that magnifies.

I saw a fishing party to-day. There were twenty fishers in it. They
were all dressed in white coats. They all sat on one stone.

“What a big stone!” you cry. You had better say, “Oh, what little
fishers!” For, to tell you the truth, I covered the whole party up with
one of my hands!

Was this a fairy fishing party? No; it was a barnacle fishing party. I
will tell you about it.

The sun shone on the water, the sea was still, and the tide was slowly
going out. It was half-low tide. A gray rock lay in the water. The
water was yet about two or three inches above the top of the rock.

On this rock were about twenty stemless barnacles, clean, white, and
acorn-shaped. They were of the size of small acorns. You must know that
barnacles grow. They are of many sizes. Some are the size of a small
glove-button. Others are of the size of a small acorn, or of the end of
your little finger.

[Illustration: A Fishing Party.]

As I looked at these twenty little fishers, the plates of the shells
were opened a little. Out of the top of each shell came a fine little
plume, like five or six tiny feathers.

This plume waved up and down in the water. It seemed to open and shut
gently, as you would open and shut your hand.

Every now and then this little plume was drawn quite back into the
shell. In a minute out it came again and waved as before. What did all
this mean?

It meant that the barnacles were having a fishing party. They were
catching their dinner while the tide was over their shells. Mr. Crab
gets his dinner at low tide, and hides at high tide. Mr. Barnacle
fishes and eats at high tide. At low tide he shuts his shell house and
clings to his place. He is waiting for the tide to come up and cover
him once more.

When Mr. Barnacle opened and shut this fine plume, it was his net, or
his set of lines with which to fish little live creatures from the
water. He tangles his prey (or food) up in his fine plumes.

Among the things he catches are tiny crabs, too small for the naked eye
to see.

When the plume net is full, he draws it into his shell. Then he empties
it into his mouth. After this he puts his plume out of his house once
more, to fish for other things. In the meantime, he feeds on what he
has taken. He has no pantry in which to store things, as Mr. Crab has.

Near this fishing party on the stone, drifted a log. On the under side
of the log were some stem barnacles. They were fishing too. They fished
in the same way, and for the same kind of things.

They opened their shells, pushed out a lovely plume, and this pretty
thing caught food in its meshes.

Does their net never break and need to be mended as the fisherman’s
net does? No doubt, if it does, a new piece will soon grow. What is his
net? It is Mr. Barnacle’s feet. If any of them are lost or hurt others
will come, just as Mrs. Crab gets new legs when some are gone. Notice
these tiny legs. They look very like a cluster of long fingers or toes.
He uses them to fish with. For what else should he use them? He never
walks nor swims.




LESSON XXXV.

A LAST LOOK AT MR. BARNACLE.


It is well to know all you can about barnacles, for you will see them
wherever you go by the seaside.

If you study them, you will not, like the fisherman, believe foolish
things about them, and refuse to believe true things.

Will it not be pleasant to think of what you know of their story? When
you see an acorn barnacle fast to a stone, you can think of the days
when he was young and went sailing about. I wonder if he calls those
days “the good old times!”

When you see a stem barnacle swinging in the water, you can think of
what a good time he is having, fishing with his pretty feet.

The stemless barnacles also have, from their shape, a name which means
_acorn_. You will find the Latin names easy when you are older and
study more.

The acorn shells can live out of water for a few hours at a time. When
the tide is low, many of them are left high and dry. But if they should
be out of water too long, they would die for want of food and water.
Perhaps, also, the dry heat of the air kills them.

If you wish to study them for yourselves, take home a stone, shell, or
stick, with some of them on it. Put it in a bowl of sea-water. Soon
they will open their shells and begin fishing.

Those barnacles which grow fast to living fish, sharks, or whales, bury
their heads and tubes in the skins of these animals. I wonder if the
whales and sharks feel them and do not like them.

The barnacles that make the most trouble are those which fasten upon
the outside of ships. The bottoms of ships are often covered with
barnacles. They make the hull of the ship rough and heavy. That hinders
its motion through the water.

In such a case the ship must be put into a dry dock. There it is
scraped clean. Because of this trouble and waiting, sailors dislike
barnacles. They often say that they wish there were none.

In some parts of the world there is a large kind of barnacles. People
eat these as we eat oysters or mussels.

You need not expect to see the young barnacles swimming about in the
water. They are very tiny creatures, of the shape of an apple-seed. If
you should see them, I think you would never guess what they are.

For a great while people thought barnacles were not worth much study.
They called them “shell fish,” and did not dream what wonders were
hidden in their shell-plate cases. At last, when wise men knocked
at Mr. Barnacle’s house door, and said, “Come out and tell me your
secrets,” they found he was a most interesting little creature.




LESSON XXXVI.

FLOWERS OF THE SEA.


There are flowers in the sea as well as on the land. Under the waves of
the ocean are fields of green sea-grasses and groves of great sea-weeds
like trees. Diving-men go down to the sea-bottom and walk about. They
often find it hard to move in the tall weeds. The weeds tangle the
men’s feet. The divers feel as you would among the brush and vines of
a great wood. There are splendid sea-plants of all colors,--red, pink,
white, green, brown, purple, yellow, and orange.

[Illustration: An Ocean Garden.]

The leaves of these sea-plants are of many shapes. They are round or
long; they are flat or curly. Some are cut into fine fingers; many are
like fringes; they have spots, dots, or knobs upon them that shine like
silver and gold.

The sea has also another kind of flowers. These are animals or fishes
that look more like lovely flowers than like any other thing. We call
them sea-flowers or animal-flowers. We name some of them after dainty
little plants that grow in the woods in spring.

The name “flowers” which we give to these is only a pretty fancy.
You must know that really they are a kind of animal. It is, then,
flower-animals that we shall now study for a few lessons.

You have read of animals made upon a ring pattern; these flower-animals
are made upon a star pattern.

The pattern on which they are made is very simple (see cut), and yet it
is so built upon and changed that the members of this Family are among
the most lovely of animals.

[Illustration]

These animal-plants have, from their odd and pretty shapes, such names
as the sunflower, the aster, the fern, the crown, the fan, the pen, and
so on. I will now tell you about one of them.

Early one day I went from my door to the beach, which was near, and
there I saw a lovely object.

The water was very still and clear, and floating in it was something
all rose and cream color.

This pretty thing was as large as a very large dinner-plate. It was not
flat, but shaped like half an orange, with the rounded side up. It was
of a fine rose color, and as clear as jelly. It looked much like pink
jelly.

From the centre of the top to the edge went lines of a deeper pink.
There were also dots around the outer edge. This edge seemed to have
a soft full ruffle of cream color about it. Looking closer, I saw that
the under side was not flat. It was shaped like a bell or an open
parasol. It had something which looked like long leaves, and which
opened and shut.

But this was not all that I saw. From the darker lines on the upper
part of the bell ran out long pink arms. These were almost a yard long.
Their edges had full ruffles. They were of a cream color, like soft
lace.

[Illustration: Fig. 1.]

[Illustration: Fig. 2.]

[Illustration: Fig. 3.]

These long arms hung down in the water, which spread out their pretty
edges. With a soft and gentle motion they waved from side to side.

In my boat I went quietly near this creature. It floated here and
there, spread out in all its beauty. I kept near it to watch it. This
lovely thing was a jelly-fish.

It was easy to see that the creature was of a star pattern, but it had
four, and not five rays. Its plan was like Figure 1. If these rays are
bent down, you will see that they may form the frame of a bell-shape,
like Figure 2. The ends of these four rays often run out into arms,
like Figure 3. All the soft pink-and-cream jelly-like stuff fills up
between the upper part of the rays and gathers into the ruffles along
the edge.

This is the plan on which the jelly-fish is built. His frame is built
of four rays. The four parts between the rays may be again divided and
be eight and not four. Again, there may be sixteen rays instead of
eight. But the plan is the same.




LESSON XXXVII.

THE LIFE OF A JELLY-FISH.


It is from the clear stuff between the rays, the stuff which forms the
bell or disk part, that the jelly-fish has its common name.

It has also another name, which means _nettle_, from the plant called
a nettle. The leaves of this plant can prick and sting your skin, and
make it burn. The fine, long arms of the jelly-fish can sting in the
same way.

The jelly-fish is nearly all water. It is made of flesh as fluid as the
white of an egg. If taken from the water, jelly-fish die in a very
short time. They die by drying up. A very large jelly-fish will dry to
a thin, small skin.

I do not know of any other living creature so soft, or so nearly all
water, as a jelly-fish. And yet these are true animals. They can hear,
see, feel, and, no doubt, can also taste as other animals do.

All along the edge of the bell part you can see some dark dots, which
are the eyes. Some of the jelly-fish have these little eyes bare; that
is, they have no lid or cover over them. These are called bare-eyed
jelly-fish. Others have a little hood like a lid over each eye. Also
along the bell part are little sacs which take the place of ears. The
long arms which droop from the edge of the bell are the feelers. These
are used to touch things with. They wave gently to and fro and help the
fish to move through the water.

Up in the centre of the under side of the bell is the mouth. It has
over it a little fine frill. Even a jelly-fish, you see, does not wish
to keep its mouth wide open all the time!

Below the mouth, the jelly-fish has fishing-lines or nets, as the
barnacle has. The soft, pretty ruffles move up and down in the water,
and catch things to put into the mouth of the jelly-fish.

It would surprise you to know what large and hard things these soft
jelly-fish can soften and use as food. Fish, crabs, shell-fish, are
caught and eaten by jelly-fish.

There is something in the jelly-fish which can dissolve these hard
things. He often casts out from his mouth-sac the harder and larger
shells and bones. He does this as you would put from your mouth
nutshells or plum-stones.

[Illustration: The Jelly-fish.]

How do the jelly-fish move in the water? They have no swimming-feet as
Mr. Crab has. They have no fins, as the fish has. Some of them move
by spreading out the bell, or round part, of their bodies, and then
drawing it up again. This motion, which is like the rise and fall of
your chest when you breathe, drives them through the water.

Other jelly-fish have a motion more like the opening and closing of
the hands. Some have little oars, paddles, or hairs on the edge of the
disk. Some seem to open and close as you would slowly open and shut an
umbrella.

The swimming-bell of the jelly-fish is often called the umbrella from
its shape. This bell has little fine muscles through it, by which it
can spread out and draw together. You know you have muscles by which
you can move the parts of your body.

On the under side of the swimming-bell, is a flap called the veil. This
flap turns inward, and the little fine muscles spread over it. This
veil is pulled together in the act of swimming, and pushes out the
water from the bell. Then the bell spreads and takes in more water, and
again it is driven out. A boy in swimming parts and pushes the water
back with his arms, the jelly-fish has no arms or legs, but still it
moves about easily.

I told you that jelly-fish could sting. They can also shine. They can
make a fine bright light, something as glow-worms or fire-flies do, but
more steady. From this power, they have been called Lamps of the Sea.
I have seen the ocean bright with them for miles. It looked as if all
the stars had fallen from the sky, and were glowing in the water.

When the jelly-fish shine so, the light is like a ball. It is not in
straight lines, long, or square. It is round, like fire-balls, or balls
of melted iron, or of glass. These balls are sometimes red, or blue, or
white, or green, or yellow.

Jelly-fish differ much in size. Some are so small that you can hardly
see them; some are as large as a split pea. Then some are the size of
a dime, of a dollar, of a plate, and so on, up to the size of a huge
wheel.

As they are of many sizes, so they are of many shapes, as I told you
at first. They are like balls, fans, bells, bottles, plumes, baskets,
cups, flowers.

And now, here is another odd thing to tell you. You know that when
Mr. Barnacle is young he swims about. When he is grown up, he settles
down to stay in one place. The jelly-fish stays in one place, and
grows fast, when he is young, but when he has grown up he swims about
wherever he chooses. I wonder which is the better way! Which way would
you children like best?

[Illustration: Flowers of the Sea.]

Some of the jelly-fishes come from an egg. Some of them come from what
is called a bud. Let us look at them from the bud or from the egg. The
egg at once fastens to some solid thing on the sea-bottom. It grows
into what looks like a plant with stems and branches.

On these branches are little cup-shaped buds. These buds are so many
little jelly-fish growing on one stem. This is the larva state. After a
time, these buds open, and a young jelly-fish breaks from the slender
stem, and at once goes swimming away, as happy as a jelly-fish knows
how to be.




LESSON XXXVIII.

SEA-STARS.


Now we come to another animal who seems to be made on the star plan.
Here you see pictures of him in the water, where he has his home. Is he
not a pretty thing?

The jelly-fish has one of his names from his shape, and another
name from his power to sting. This fish gets one name from his
shape,--star-fish. And he has a long, hard name from his coat. His coat
is a thick, tough skin. It has upon it prickles much like those of a
hedge-hog. Most of them have five rays, or ten, because each single ray
has been made into two, and so on.

All of the star-fish do not keep to the plan of five. The sun-star has
twelve rays. He is of a splendid, bright-red color. These animals seem
to be made on the star plan; the grown-up sea-stars show this shape
most clearly, but it is never perfect; the young ones are two-sided,
not star-like.

From their general shape they are called “stars,” from their skins,
“rough or hedge-hog coated.” This skin is really their skeleton: they
have their bones outside like the crabs and some other creatures.

[Illustration: The Ray Family at Home.]

The crab’s skeleton is hard, the sea-star’s is more like a tough skin
filled with little plates or spikes of shelly stuff. Sometimes these
little plates lock together, sometimes they merely lie near each other,
so some of the stars have much softer coats than the others. In the
water these coats are tough and bend like leather. When they are dry
they are brittle. If you want a dead star-fish to bend, drop it into
water.

I will tell you of some kinds of star-fish, and then will tell you how
they grow.

In the picture you see a star-fish with the thin, crooked rays, or
arms. He is called a sand-star, because he likes to lie close to the
sand on the sea-bottom. He is of a sand color.

The one with the curled arms, like plumes, is called the brittle-star.
That is because he breaks so easily. He is a very queer fellow. When
things do not please him, he drops all to pieces. It would be a queer
thing, if, when you feel cross or afraid, you could throw yourself down
and fly to pieces, jerking off your head, your arms, and your legs!

You have heard how crabs can drop off a claw, and then another grows
out. You also know that a spider does not mind much about losing a leg
or two. These facts cause us to feel sure that these creatures do not
suffer pain at the loss of a part of their bodies. If the loss of legs,
claws, or rays caused pain, these animals would not be so ready to drop
them.

There is no other creature that breaks itself so readily and so
entirely as the brittle-star. It will throw off all its rays, and they
will float away in many directions, while the little disk is left alone
to sink or to float.

When the star-fish loses one or more, or even four rays, others will
soon grow. All the animals of this family renew lost parts even more
easily than crabs do.

It is very hard to get a brittle-star out of the water. As soon as it
feels a net or scoop or the upper air about it, or a pail of fresh
water rising gently around it, it breaks into many pieces.

On the end of every ray is a little sharp eye. When you frighten Mr.
Brittle-Star, off swim his legs, every one by itself, and each has its
one eye to look out for it. I never saw anything else so queer; did you?

The strong, prim-looking star-fish, with five points, is called the
cross-star. It is the common, or pattern star-fish. There are many
other kinds. I will tell you in the next lesson of one very pretty
kind. You must go to larger books to learn all that is known about
these strange and lovely creatures.

We will look at the model, or cross-star. Turn the animal over. The
mouth is in the centre of the under side. Do you not find there is a
seam, or groove of the hard skin, all the way down the centre of each
ray? From the mouth a nerve runs down to the point of each of the rays.

Along the centres of the under openings in the rays are set very,
very many little blunt points. These points are like tiny tubes close
together. It is on these that the star-fish can walk or creep on the
bottom of the sea, or over rocks. The star-fish seek their food as they
crawl slowly about.

Star-fish are very greedy. They are always hungry. They make the
fishermen much trouble by eating the fish-bait off their hooks. They
also devour oysters. When they get into an oyster-bed they are as bad
as the drill. When an army of star-fish go to a part of the coast where
oysters grow, the oysters are soon killed.

The star-fish are of many bright and pretty colors. They are green,
brown, gray, red, pink, or with several colors on the same star.

When they are dead, the flesh, which has much water in it, dries away.
The tough shell-like skin is left. You can dry them by pinning them on
a board. Leave them for a few days in the sun and wind. If you do not
pin out the rays, they may curl up.

They look better kept in alcohol, but that is not a good way for
children. I fear the bottles would soon be broken.




LESSON XXXIX.

A SEA-CHANGE.


The star-fish lay a great number of eggs. Let us see what happens to
eggs of one kind. They are not dropped one by one into the water, or
strung on threads like chains.

They stick to the under-side of the parent fish, which settles on the
sand or rocks, resting on its back, and bends up its five rays, like a
basket, to hold and protect the eggs.

You see that in this state the parent can neither walk nor eat. And
although star-fish are both greedy and restless, when they have eggs
to take care of, they patiently lie quiet for ten days, until the eggs
hatch.

In those ten days the parent star-fish cannot eat nor move. But at the
end of ten days, the eggs hatch out the larvæ, and they float away.
Then the star-fish finds that its work is done, and it bends back and
begins to walk, swim, and fish.

Many of the larvæ, when they first come from the egg, have no rays,
and do not look one bit like star-fish. They look like wee specks of
barrels, with little hairy hoops, and a plume of hairs on one end.

The larva can swim; the hairs help it through the water. Slowly it
begins to change its shape and to lose its loop of hairs. All it wants
is to swim and to grow. When no larger than a flaxseed it looks like
the grown-up star-fish.

A most curious thing is the lily-star egg, which fastens upon a coral,
or something firm and hard. Then it takes as fast hold as the barnacle
on the rock.

It shoots up a stem, and on the top of the stem grows a cup like a
lily-bell. It does not look like a star-fish, but like a lovely lily.
Fine plumes are waving from its cup.

Some kinds of star-fish have larvæ that take other shapes. I cannot
tell you about them all. But only the feather-star grows fast to some
object for the larval state. In that state they do not look at all like
the parent. Finally, like the jelly-fish, they change their shape, get
loose, and swim off to see the water-world. Then they are like their
parents.

[Illustration: Water Babies.]

Now let us look again at our star-fish. The little things like tubes
on the under-side are each one set in a grove. They are full of fluid,
and each has a tiny sucker. The star-fish can move them. They not only
serve for feet, but for hands, to catch, and hold, and kill his prey.

Most of the star-fish are dull and slow of motion. There is one kind
which moves quickly. It is called the Snake’s-tail-Star, from the shape
of the rays, which are long and thin.

There is one of these animals often found on the coast of the Southern
states, which has all the space between the rays filled up with a hard,
stony, or shell-like matter. So the shape of this animal is not like
a star. It is like a flat box with five sides. There are some little
loop-holes quite through this hard box. On the middle of the top is
the pattern of a five-pointed star-fish, like a picture! It is not a
star-fish, but an urchin.

In this Radiate, the disk spreads out, so as to include, or shut in,
the rays. On the one hand, there are some star-fish that have the disk
very small. They seem to be all rays and no disk.

People who have studied star-fish divide them into six families. I have
told you about all but the fifth. The fifth family are of such a queer
shape that they are called cucumbers--Sea-Cucumbers. The Chinese like
to eat them, and ships are sent out to fish for them. They grow in the
shallows, near the islands in tropic seas. We have some also on our
coasts.




LESSON XL.

THE STAR-FISH WITH AN OVERCOAT.


There is a very pretty star-fish called the Sea-Egg, or Sea-Urchin.
This creature has not five points or rays; it is in the shape of a
ball, somewhat flattened.

[Illustration: Fig. 1.]

[Illustration: Fig. 2.]

[Illustration: Fig. 3.]

Do you say, “Can this belong to the Star-fish Family, when it has no
rays?” Well, let us see. Let Figure 1 represent our Ray pattern. Bend
the rays up, and the plan looks like Figure 2. Then bend them until
the tips touch, and you have the form of Figure 3. The cover of this
star-fish, called the sea-urchin, is not tough and skin-like; it is
hard and shell-like.

If you look at it, you will see that it has up and down it lines of
knobs and dots set in double rows. You will find five double lines of
large knobs, and as many lines of small dots between the larger ones.

Do not think that you can see these marks as soon as you find a
sea-urchin. By no means! The sea-urchin wears a fine thick overcoat,
which hides his shell.

[Illustration: Well Dressed.]

I knew a boy who found a number of sea-eggs lying on the beach. He
cried out, “Oh! look at all the chestnut burrs in the water!” The
sea-egg when it is alive looks much like a chestnut burr, ripe, but not
open. It is covered all over with thorns or prickles like the burr,
and the water gives it the dark brown color.

Now let us look into this matter. You have read that a cross-star-fish
has along the under edges of its rays many little tubes full of
something like water. He can move them, and upon them he walks.

[Illustration: Undressed.]

The sea-urchin has hard, sharp spines, which cover all the shell, and
look like a rough coat. In the pictures you see the urchin with his
shell bare, with his shell half bare, and with his full overcoat of
quills. When the shell is bare, you will see upon it little lines of
points or knobs. These are very pretty, but they are for use, rather
than for beauty.

On every tiny knob is placed a spine, and the urchin can turn and move
his spines, in all directions, just as easily as you can move your arm
at the shoulder-joint.

When the urchin is alive, the quills stand out all about him. After he
is dead, the quills drop off.

Between the rows of knobs are five double rows of holes, like
pin-pricks. Out of these grow such little suckers as I told you the
star-fish had.

In some countries the sea-urchins are small--not much larger than a
dime. In warmer seas the urchins grow large, even as large as a large
orange. People often use these larger ones for food.

The sea-urchin walks on his spines, as the cross-star-fish does on his.
But as the quills of the urchin are all around him, like a ball-cover,
his walk is a roll! By the little suckers he can cling to the rocks,
and he can climb up their sides.

Turn over the bare urchin shell, and you will see that while at the top
it has no opening larger than a pin-prick, on the under side there is a
hole where the curved rays do not come entirely together. You see the
urchin must have this open place for his fish-lines, and to put food
into his ever-hungry mouth.

Since the sea-urchin eats so much, he must grow! Does he?

Yes, the sea-urchin grows, and it cannot cast its shell as a crab can.
It has not a soft skin as you have, yet his shell is never too tight.
How can the shell expand as the urchin grows?

The shell is made up of a great many little plates, or scales. As the
urchin within grows and needs more room, these little scale-plates grow
larger all around.

Here is a strange thing: these wee plates are set like bricks in a
dome. You know the urchin is made on the five-ray pattern bent like a
flattened ball.

About the body of the urchin, within the shell, is wrapped a soft,
pretty, silk-like mantle. This mantle lines the shell. It takes lime
from the sea-water and builds it into more shell along the five edges
of these wee plates. It also adds new plates.

So, as the urchin keeps growing all the time, its mantle is building
upon the plates all the time. The house or coat, whichever you choose
to call it, grows with the growth of its owner. I think your mother
would be glad if she could find you a coat to grow with the growth of
your body.

The shell part of the urchin is gray or greenish gray. The quills are
often red, brown, pink, or purple. When a number of these urchins are
fast upon a rock, they look like a bed of lovely fringed flowers.

The urchins are able to bore holes even in the hard limestone rock.
They bore these holes to live in, and, as they grow, they make the
holes larger, but not the openings. So, after a time, they are shut
into a prison which they have dug for themselves. They do not do this
on our coast.

On the coast of Spain you will find the rocks covered with these
urchins, fixed in holes. No doubt they feel that stone walls are safe
walls. If they had wished to get away, and go and come freely, I think
they could have made their doorways as large as themselves.

There is much more to be learned about sea-urchins. You will do well to
study them when you can. In fact, the longest life is not long enough
in which to learn even what is to be learned of very simple and common
things. There is danger that when we have learned a little we shall
become proud, and that we shall not take the trouble to learn the very
much more which we do not know.




LESSON XLI.

THE FLYING FLOWERS.


You have just read about some of the Radiate Family. From their beauty
they have been called Flowers of the Sea. We will now hear about some
insects which might be called Flying Flowers.

I knew a little boy who, the first time that he noticed butterflies,
cried out, “Oh, see all those flowers flying!” That was a pretty idea.
It well described the butterflies, as you will see when you come to
read about them.[20]

There is another family of insects which also deserves the name of
Flying Flowers. Their shape, colors, and motions are very lovely. These
insects are the Dragon-Flies.

I am sorry that such beautiful creatures have had harsh names given to
them. They are called Dragon-Flies, Horse-Stingers, Darning-Needles,
Spindles, and so on. These names have nothing true in them. These
pretty insects never harm any one.

The French people call them Little Ladies. Now, that is a nicer name.
It is given to them because they are graceful and pretty, and also neat
and delicate, in their looks and motions.

[Illustration: A Flight of Dragon-flies.]

I knew a man who called these insects Air-Jewels. That was because they
are almost always on the wing, and their eyes and bodies flash and
shine like precious gems.

I have known silly people to start and scream when one of these
dragon-flies came darting by. That was foolish; they might as well
scream at a rose or a violet. There is no need of running away from
one of them. The great trouble is that they are so swift and shy, you
cannot easily catch one if you wish to examine it.

The dragon-flies are cousins of the termites, the may-flies, and the
lace-wing flies. They have four large, fine, lace-like wings, divided
into a great many spaces or meshes.

The two pairs of wings are nearly or quite equal in size. The head
is large. The body is long and light. They are very active in their
motions, and are very seldom at rest. They fly so swiftly that you
can scarcely see their thin wings, but only the flash of their
bright-colored bodies.

Dragon-flies like damp or wet places. You will find them above lakes
and ponds. They fly over marshy places or by the edges of quiet streams.

Go out to some still, silver-like pond, where the tall trees stand in
a ring about the water. The ferns, the tall yellow spikes of the St.
John’s-wort, and the blue clubs of the arrow-plant make a wreath around
the sandy margin. There you will see hundreds of gay dragon-flies
darting up and down. They swing in the sunbeams, as if glad to be alive.

In their great beauty the dragon-flies are as pretty as the
butterflies. Like them, they love the sunshine. They are the
children of the summer time. The hotter the weather, the happier the
dragon-flies seem to be.

Let us look for a little time at a dragon-fly. It belongs to the class
of the ring-made creatures. Its body is made in rings, and its feet
and legs are jointed. The body is very long and slim. Some kinds of
dragon-flies have the body rather flat, but usually it is round, is
slimmest in the middle, and thickens a little both at the tail and
where it joins the breast.

The wings of the dragon-fly are horny and of iris or golden hues.
Sometimes the body is a vivid blue or bright green. Sometimes it is
banded or spotted with yellow or scarlet.

The wide wings look like delicate lace spread on a fine frame. A little
child who found one of these wings, brought it to me, saying, “I dot a
dood piece of lace!”

The head of the dragon-fly is large, and has on each side what you
would call a great eye. But like that of the house-fly, this eye is
made up of many eyes set so as to seem to be one. I hardly dare tell
you how many there are--over twelve thousand! Through these wonderful
eyes the light plays and flashes like fire. Between these big eyes
three little simple eyes are set in a band across the head.

The dragon-fly has a queer mouth. The jaws are hidden under two thin,
skin-like lips. These move up and down as it eats. It does not suck
food, like the butterflies and house-flies, but eats after the manner
of the beetle.

Thus, you see, the dragon-fly belongs to the great Division of the
Eaters, not of the Drinkers. Instead of feeding on nectar, as we would
think so lovely a thing should, it eats insects.

All its life long, from the egg, it is always greedy, because it is
always hungry. It spends all its time hunting for food. Who could count
how many small insects a dragon-fly, eats in his short lifetime?

LESSON XLII.

UNDER THE WATER.


Now let us hear the story of the dragon-fly from its beginning. While
it is an egg, a larva, and a pupa, it lives under the water. Only when
about to burst from the pupa-case, and at last get its wings, does it
leave the water and seek the upper air.

In all its early stages the dragon-fly lives in cool, still shallows,
among green and graceful water-plants. There the sunshine glows all
about it, as it darts over the bottom of the pond, hunting for food.

The mother dragon-fly, as she flits over the water, drops her eggs upon
it. They sink to the bottom. She may put them into plant stems. Their
cases are waterproof. If the eggs are not eaten up by beetles and other
fellow-citizens under water, they are quite safe, and soon the larvæ
hatch out.

[Illustration: Home of the Dragon-fly.]

Most insects move quickly in the larva state, and are dull or quite
asleep in the pupa-case. This is not the way with the dragon-fly. He
is busy and strong all his life. The egg settled upon the pond bottom
is quiet; the larva moves about, but is rather slow and lazy. The pupa
dashes here and there, and frightens all the little animals in the
pond. At last the perfect insect rises on the wing. It darts about with
almost the swiftness of light.

The larva of the dragon-fly is gray. It has six legs. It is always
hungry, and feeds on small water-animals, as beetles, grubs, shrimps,
leeches, and their young.

This larva does not run after its food, but lies waiting for it. On the
bottom of the pond, hidden in the shadow of a leaf, root, or stone,
or seated on stems or leaves that are under water, the larva waits
patiently for its prey to come by.

Did you ever see a person with a net for catching insects? This net
is a fine bag set on a little hoop. The hoop is fastened upon a long
handle. Sometimes the handle has joints, and will fold up. As insects
dart by, the person with the net brings it down over them with a quick
motion.

The dragon-fly larva has something much like this with which to catch
its food. The lower jaw is fastened by a hinge to a little jointed rod.
The rod, and the jaw-plate upon the end of it, when not in use, are
folded down upon the head of the insect.

The plate has fine teeth upon its edge. When the prey comes by, the
larva snaps out its rod, with the plate, as if they both were on a
spring, and so catches the things that are swimming along a little way
off. They do not see their foe, and do not know that he can reach so
far with his sweep net.

The teeth on the edge of the plate shut up, and then the rod folds
back, and puts the food into the hungry larva’s throat. I suppose the
little creatures that swim along feel quite happy and safe, and then,
all at once, out springs this weapon, and they are gone.

But this little plague of the pond is not quite safe himself. There are
some other creatures down under the water that eat him. All nature is a
kind of game of “tit for tat,” you see.

The larva of the dragon-fly breathes air. He has no lungs as you have,
but gills as a fish has. How does he get air?

Through his body goes a long tube. The tube ends in a horny point at
the tail. This point is made of five very fine spikes. These spikes and
this tube are able to take from the water some of the air that is in
it. Thus he gets air much as a fish does.[21]

This spike on the tail of the larva has a very strange use. It shoots
out the water which it has taken in, as you would shoot water from a
squirt-gun. It shoots the water out with such power that it drives the
larva along in the water.

Did you ever see a steamboat driven through the water by a screw or
wheel at the stern, or hind part? What do you think that the man who
first made such a boat said? He said that he took his idea of how it
should be made by seeing this queer larva move in the water.

When this creature seizes food, he likes to strike it from below. He
rises under it in the stroke, as the shark does. Dragon-fly larvæ are
very bold. They can eat large and hard insects.

When the larva changes to a pupa, it becomes more lively, fierce, and
hungry than ever. It does not change its form at this time as much as
most insects do.

The dragon-fly pupa has six legs, and each foot has strong hooks on it.
Its color is pale brown, clear and shining, and its case is horny. Some
rings of the body have horny spikes upon them. Upon the case of the
chest is a pattern like wings.

These pupæ dash about the bottom of the pond, swimming or running, and
eat almost everything that lives there. The body and head of the pupa
are thicker than those of the grown-up dragon-fly. They are made for
seizing and killing prey.

When it is nearly time for the pupa to come out as a dragon-fly, the
case grows clearer, like glass. The large, beautiful eyes grow brighter
and brighter, and the pupa leaves the deeper part and gets near the
edge of the pond.


FOOTNOTES:

[21] See Seaside and Wayside, No. 3. Lessons on Fish.




LESSON XLIII.

A HAPPY CHANGE.


When the close of the pupa state draws near, the coming dragon-fly
loses its fierce appetite. It seems to feel tired and heavy. It
breathes slowly, as if it could not get air enough. The body has
changed inside the horny case, and the time is near when it will leave
the water for air, and walking for flying.

Once the larva wanted nothing better than to chase bugs about under
water. Now, all at once, it longs for the free air and for the sun. It
needs no one to tell it what to do. In some way it knows exactly how it
should act.

This tired pupa now seeks the stem of some tall reed or grass that
grows in the water. Slowly it crawls up the stem. The hooks on the feet
take fast hold as it goes, and it keeps on until it is nearly a yard
above water.

The hooks, though very small, are so sharp and hard that they can go
into wood. When the pupa is as high up as he wants to be he drives the
hooks into the stem. Thus it will hold firm even when it twists and
struggles hard.

The pupa likes best to find two reeds or stems near, so that it can
take hold of both and swing between the two. Then, like a child in a
swing, it begins to sway to and fro. Now, as it sways, a strange thing
happens. The hard pupa-case splits open upon the back, and look, inside
the case, we see the perfect insect, with its wings!

The pupa-case is firmly held by its hooked feet, while the new insect
twists and pulls, and so gets free; and little by little its head,
legs, wings, and long body come forth, and finally hang only by the
last ring of the body.

[Illustration]

Then you would think it was dead. For after it stretches out first one
leg and then the other, it hangs by its last ring, stiff and still. But
it is only resting. After about fifteen minutes it awakes. Taking hold
firm with its feet upon a stem or leaf, it lets go its hold upon the
pupa-case. That is left hanging by its hooks in its place.

Here is now a dragon-fly, with large head, with two great cluster eyes,
six legs, four wings, and long, bright-hued body! And now, at last, it
can breathe freely through all those tubes and air-holes you have been
told about.

Still the insect does not look like the full-made dragon-fly. The
colors are dull, and the wings are folded up. The body is soft, damp,
and too short. The big eyes are dim.

[Illustration]

As if half asleep it still clings to the stem, not far from the case,
which is the old shape of itself. Hanging to the reeds by the pond you
will often find these old coffins, if you look for them.

The new insect is drawing in the sunshine and fresh air. It stands
still and breathes hard, filling its new body with pure, dry air. Now
and then its wings quiver.

As they quiver they spread out, fold after fold, as silken banners wave
out upon the air. Then at last they are spread out wide, in all their
beauty. The dragon-fly has reached its last and highest state. It can
sail away where it pleases on its new wings.

As the wings grow larger, the eyes of the dragon-fly grow brave and
bright; its body dries. Then it gleams like a jewel. Its fresh colors
come out clearly. It feels strong and active.

Then, all at once, it uses its new wings. It rises into the air and
flashes here and there, just as hungry and ten times swifter than ever
before.

The flight of the dragon-fly is called hawking, for it is like the
motion of that strong bird, the hawk. If it gets caught in a place
where its wide wings cannot turn, it can fly backwards and get off
safely. In a place where the wings might be injured by striking against
leaves or branches, it flies out in this way.

When dragon-flies are dead, the great beauty of their bodies passes
away. They fade and grow dull, as when they first came from the
pupa-case. The scarlet, yellow, blue, or green turns to a dull drab. So
you cannot keep them as well as you can keep beetles. It is life that
gives the dragon-fly its splendid beauty.




LESSON XLIV.

THE DRAGON-FLY AND HIS COUSINS.


The dragon-fly eats almost every kind of insects which you have thus
far read about. Beetles, spiders, flies, centipedes, fresh-water
shrimps, and polliwogs are its food.

The dragon-fly is a larva for a year. It is a perfect dragon-fly only
a part of one summer. You will find the most dragon-flies in July or
August. When the frost comes, they die.

Dragon-flies are very strong; they are fond of chasing other insects.
They seem to catch and tear them for the mere pleasure of pulling them
to pieces. They also fight with each other, and Mr. and Mrs. Dragon-fly
have some hard battles.

The dragon-fly does not have a long lip, or mask, set on a rod, as
the larva had. They fly so swiftly that they do not need such help in
getting food.

Few insects are so easy on the wing as this, and few have such
beauty of wing. Yet I think, after all, that the chief beauty of the
dragon-fly is in its eyes. These are like two great flaming jewels.

The eyes are beautiful, for this clear, glowing light in them; the
body, for vivid color; the wings, for their lace-like texture. Each of
the wings has a dark spot on the front edge. Often, in flying, this
spot and the line of bright color of the body, almost like a streak of
fire, are all that can be seen of the insect.

[Illustration: The Dragon-fly and his Cousins.]

There are several kinds of dragon-flies. These are different in color
and size, and in the shape of their bodies. One, with a very long,
thin, dark body, is called the Darning-Needle. One, with a thicker
body, is called the Ringed-Club. Its body is largest at the tail end.
This one is dressed in black and gold, and is large and strong.

A smaller kind of dragon-fly, which has no spots on the wings, is
called the Little Lady. This is among the prettiest of all; some of
them are bright red; some a clear light blue. They look more like
creatures in some dream about fairies, than like real live insects, for
they flit here and there like streaks of gay-colored light, and you can
scarcely see the wings on which they fly.

The dragon-fly has some very handsome relations. One of these is called
the Lace-Wing. The head and body of the lace-wing are bright green, its
wings are like white gauze; but its chief beauty is in its eyes. Some
call it the Golden-Eye, because its eyes are like a drop of amber, or
melted gold.

The veins in the wings of the lace-wing are very fine. As the light
falls on them, they change in color, and look like pink, red, blue,
green, or gold threads.

These lovely lace-wings do not like the bright light of the noon-day,
as the dragon-fly does. They prefer to come out in the moonlight, or
when the sun is setting.

The lace-wing is not a water lover, as the dragon-fly is. It lays its
eggs on leaves, and every egg is held upon a little silken stem. The
stem is much like the silk which the spider spins. These eggs are laid
in groups.

When the young lace-wings come out of the eggs, they feed on the little
aphis. You remember the aphis makes the honey that ants are so fond of.

In two weeks these larvæ change to pupæ. To do this the lace-wing larva
spins a nice silk ball, in which it goes to bed for a nap while it is a
pupa.

In this, you see, it is not at all like the young dragon-fly, which
hunts and runs about while it is a pupa. The ball of the sleeping
lace-wing is about the size and shape of a wild pea, or vetch seed.

The lace-wings are short lived. One summer makes a lifetime for them.
In a summer they grow from infancy to age, make all their changes, and
live out their time as complete insects.

When the lace-wing is dead, it loses all its fine colors in a very few
hours.




LESSON XLV.

THE WINGS OF THE DRAGON-FLY.


We can find no better example than the dragon-fly, of the way in which
insects behave when they leave the pupa-case.

You know that this case is horny or tough, and always seems smaller
than the grown-up insect; so the insect must be very closely packed in.

No person could pack a new insect back into the case it has just left.

While the dragon-fly pupa is under water, the case is kept tough, and
yet soft enough to bend. But when the pupa crawls up the stem of the
plant into the air, the case soon dries and becomes brittle.

As the fly struggles within, the dry case will easily split. The little
wet coat, which covers the body while it is in the case, makes it more
easy to slip out of the shell when it cracks open. You know if you have
on your finger a ring which is too tight, you can pull it off if you
wet your finger.

The wet coat of the fly in the case keeps the wings from being hurt by
their close folding. After they are dry and spread out, they are easy
to break. Then it is very easy to hurt or spoil them.

The fly seems to know this, and is careful of its wings. In the act of
unfolding, the fly holds its wings from touching any object, even its
own body.

When the dragon-fly gets free from the case, it knows just how to
spread its lovely wings into perfect shape. It stands quite still, and
far enough from stems or leaves to keep its wide wings safe.

It does not move its wings, but lets the air do the work, while it
holds its bent body away from the wings. The quiver you see through it,
now and then, is a motion of the body; and I will soon tell you what it
means.

When the fly first comes from the case, its wings are soft, and will
bend as easily as wet paper. After they are dry, they are like thin
plates of glass. These wings have very many nerves through them. Their
frame is like a fine net-work, and, as it is touched by the air, it
spreads slowly to its full size. If, at this drying-time, the wings are
hurt, they will never come to their right shape.

[Illustration]

If any one should try to help a dragon-fly out of its case its wings
would be ruined and never take their right shape. Human hands are too
clumsy for such work.

When first the pupa comes from the case, the wings and body are of a
dull, faded color. But as it stands in the sun and air, you can see it
change from minute to minute.

Fold after fold of the wings shakes out; ring after ring of the body
stretches to its proper length; the joints of the legs come to their
right shape and firmness. From all the body of the insect a mist seems
to pass away; and the colors of the fly come out, and red, blue, green,
gold, shine in beauty.

Now let us look closely at these fine wide wings. Although they are so
thin, like gauze, yet they are double. There is a surface on each side,
spread over a very fine frame. The parts of this frame are small as the
finest hairs.

And yet, though so tiny, they are all hollow. They are tubes or pipes.
They carry through the wing, air and a very thin white fluid, which is
the blood of the insect.

Now that you know this, can you clearly see how the wings expand? As
soon as the dragon-fly is born from its pupa-case, air and this thin
fluid are driven through these fine tubes. As they fill, they stretch
out, and the thin surface which covers them spreads with them.

If you notice the fly as it is thus getting its shape, you will see
that quiver which I spoke of. That motion is the pumping of air and
fluid through its tubes; and, no doubt, by this action the fly spreads
out its wings and its body. By such a motion the blow-fly spreads out
its big head.

The dragon-fly spends about fifteen minutes in getting into shape.
Sometimes half an hour is needed. After that, the fly rests for an hour
or two, before it tries its wings in the air. Very likely it wishes to
give its wings time to get quite firm and hard.

Butterflies, Lace-Wings, May-Flies, and other insects of the kind have
their wings made in this way; so what you learn about one will help you
to understand the others. You read of the Lace-Wing in the last lesson,
and in the next book you will hear about Butterflies.

The May-Flies are very pretty insects. They are something like
dragon-flies, but very much smaller, and not fond of tearing up other
insects. You will find them in moist places. The body of the May-Fly is
much slimmer even than that of the dragon-fly. The wings are unequal.
Their heads are smaller. May-Flies have two fore legs, nearly as long
as the body, held almost straight out as they fly. On their tails they
have three long stiff hairs, twice as long as the body. These hairs
spread out, fan-shape.

These insects are often called May-Flies, because they usually come in
May. But they have another name, which means the “child of an hour.”
This name is given them because they seldom live longer than one day,
and often only for an hour or two. In the egg, larva, and pupa they
live about two years; but, once born with wings, they soon die.

And how do they spend that short life? They do not eat, for they have
no mouths. As they are not hungry, they do not hunt. They spend their
whole time in flying. Their flight is a sort of dance in the air; they
rise and fall, and spin about.

[Illustration: A Child of an Hour.]

Great numbers of them come out together, spin about, and drop their
eggs in the water. But soon they flutter down, dead, among the grasses.
That is the story of the pretty May-Fly. I have been on a large island
on a day when May-Flies had come out: the air was full of their shining
silver shapes--they lit on people’s clothes, and seemed to cover them
with a gauze veil.

Would you not like to seek out in their homes, and then read and study
about, the very many strange and wonderful insects that are in the
world?
