at can see in all
directions.

They have great need of such eyes, because there are so many birds and
other hungry creatures, that want to eat them.

One day a whiff of celery coming from a garden near by, reminded Miss
Swallow-tail of the time when she was a baby and liked to eat celery.

So she flew over into the garden, and fastened her eggs to a celery bush
with some glue that she carried with her. Then she left them, and never
thought of them again.

In about ten days the babies that had been growing inside of the eggs,
broke open the shells and crawled out. And what do you think they were?
Butterflies? like their mamma, only very much smaller?

No, indeed! for you know butterflies never grow any larger. They were
the smallest green and black worms you ever saw!

As soon as they were out of the shells, they began eating the celery,
and grew so fast that in a week they were quite large worms.

They were covered with green rings and black rings dotted with yellow.
They each had sixteen short legs, and they had a flesh-colored, Y-shaped
horn hidden away under a ring above the head, that they would show when
they were disturbed.

One morning the gardener discovered that something was eating his
celery. Searching among the leaves he found all but one of the little
worms, and put them where they could do no more mischief.

Soon the little worm that had escaped his notice, had grown so fat that
he was too stupid to eat any more; so he crawled away to a dark place on
the fence and fastened himself there.

But first he covered a small spot of the fence with a white, silken
carpet, that he wove from a web which he drew from his under lip.

He then glued the end of a web to the carpet, carried the rest of it up
over his breast, and down on the other side and fastened it there.

He then bent his head down under it, letting it pass over his head, and
by bending forward and backward worked it down near the middle of his
back. After inspecting his work, he bent his head upon his breast, and
leaned against the fence.

After resting two days, he began a series of twistings and turnings
that burst open his skin from the corners of his mouth down a short way,
and worked it all off himself.

He drew his head in out of sight, and sent out a stubbed horn on each
side of it, and lo! no worm was to be seen!--but a chrysalis, like the
one his mother was sleeping in when we first found her.
