REST METCALF.

Ugh! The ugly worm! Crush it! Wait a moment, listen, while I tell you

a more excellent way. Notice on what your worm is feeding; take a

branch of it home and place it in a bottle of water with the worm on

it; then place the bottle with its contents in a large box, fastening

a wire securely over the box, to prevent the escape; then watch your

worm. Perhaps your worm will be the one so often found on the milkweed

(_asclepias_) with black and yellow stripes around his body, two little

horns in front on his head and one at the tail. If you keep him well

supplied with fresh leaves, in a short time he will eat all he wishes

and then, and not until then, will he leave the plant on which he is

feeding and travel many a long journey up and down and all around the

box, until you may imagine he has gone crazy from his confinement; but

that is not the case, as you will soon see. When he finds just the

right place, he will remain quite still to all appearances, but really

he is very busy with his bobbin of silk and glue bottle weaving a small

silken mat and fastening it very securely to the top of the box, and

the next thing you will see him hanging by his tail from this mat,

with his head recurved. Watch him and you will notice that he makes

little jerky motions. For about twenty-four hours he remains in that

same position, when suddenly he drops down his head so that he hangs

straight down; now don't leave him for a moment, for very soon after

taking that position, his black and yellow striped coat begins to split

open, right between those two little black horns on the head, as evenly

as though cut with a sharp knife and a pale green globular object comes

into sight. With a few contortions of the body the little fellow pushes

up his old coat, folding each stripe, just as Japanese lanterns fold

up, then with a dexterous movement he fastens the end of his beautiful

green chrysalis to the mat, dropping his old clothes, so closely

compacted together that you would hardly recognize them. Now for two

hours he exercises by little shrugs until the beautiful green chrysalis

hangs complete, with gold band and pure gold spots, the most beautiful

chrysalis I ever saw. Everyone exclaims, "How beautiful!" and wonders

how an ugly worm could so transform itself into a thing of beauty.

For ten days we can see no change in the looks of this chrysalis; then

it grows darker and darker until you can distinguish the veins on the

wings of the future butterfly. Then this little fellow, tired of his

close quarters, opens the door of his beautiful chrysalis and creeps

out, clinging fast to the empty nest. O, what tiny wings! But as you

watch they dry out and lengthen to three times their first size and you

behold the beautiful large Viceroy--orange-red wings with black lines

along the nervures and a row of white spots along the outer margin, his

black body beautifully spotted with white.

Or perhaps you may find, on the carrots in your garden, a worm with

black and green stripes around his body, the black stripe being

decorated with yellow spots. He will spin a long silken mat the length

of his body and to that mat fasten a swing to hang around his body,

so that by using a little glue at the end of his body the swing will

hold his chrysalis in place. This chrysalis is not as beautiful as the

Viceroy, but very interesting in its odd shape and in its development

and will well repay all the interest taken in it. Perhaps you may

be surprised by not seeing a beautiful butterfly emerge from your

chrysalis, but instead an Ichneumon fly, for often the Ichneumon fly

deposits her egg in the caterpillar's back, and he can not say her

nay; after he is nicely settled in his chrysalis this egg hatches and

develops rapidly, needing so much food that nothing is left of the

poor caterpillar or worm, but the fly prospers and soon comes forth

full-grown, from a round hole which he makes in the side of the

chrysalis.

Each variety of worm and caterpillar will reward you with a different

chrysalis or cocoon. If you are not sure of your worm place a box of

dirt in your box, for some worms go into the dirt to make the great

change. After watching these changes you, too, will say: "Don't crush

the worms! For are they not a symbol of our own death and resurrection

when we shall awake in His glorious likeness?"
