The first thing a caterpillar has to do is to eat his eggshell so that the ichneumon fly—the fellow is an enemy to my family—will not be able to find any traces of him on the leaf. Where did I learn that? I think Mother B. must have folded that thought in the eggshell, for it came out with me. After doing that duty I was so hungry that I ate the leaf on which I found myself, all day long and far into the night. Then I curled up and went to sleep feeling very quiet and comfortable. When I awakened the sun was up. I was warm and hungry, so I began to eat again. Suddenly I heard a buzzing noise overhead. Oh, dear me! I was frightened and kept perfectly still, for I thought it was that miserable fly after me, but it proved to be only a jolly bumble-bee, and I went on eating. After several days of this life—eating, and watching for enemies—something happened. I suppose that I had eaten so much milkweed that my skin got too tight to hold me, for it felt very uncomfortable and then began to crack. I had spun a little silk on the leaf to get a better foot-hold and remained very quiet for I did not feel like moving. I stretched my head a little, after awhile, and the old head-case came off, falling to the ground. Then I made violent exertions, or movements, with the muscles of my body, and finally the old skin came off. I was very much fatigued and was quiescent, not caring to stir, for several hours. I thought of the fly too, that might sting me now while my new jacket was soft, and that kept me still also. When it became harder I had to eat up the old one, and then was hungry as ever. Eat! Why I did nothing for about four weeks but devour milkweed, keep a watch out for enemies and grow too big for my jacket. I moulted four times in all, and at the end you should have seen me. My body was striped yellow, black and green, and was nearly two inches long. My head was black-banded; my face yellow with two parallel black bows, and I had two pairs of long slender, flexible filaments, like a hair, on my body. I had grown so large and strong that I wanted to see more of the world. I crawled off my leaf, down the stalk of the plant onto the ground. What a queer sensation it was, to be sure, to feel the grass and the ground! There was a rail-fence near my old home. I began to feel very weary and sleepy. I crept cautiously along until I reached the fence; crawled up to next the top rail and under it to rest awhile. My, how tired I was! I did not want anything to eat. I did not care to move, nor to speak. I caught hold of the rail and hung there for about twelve days.
