the end of one of the cocoons grew dark aлd moist. I thought that it had probably spoiled, and wanted to throw it away. But then I thought that perhaps it began that way, and so I watched to see what would happen. And, indeed, something began to move at the wet end. For a long time I could not make out what it was. Later there appeared something like a head with whiskers. The whiskers moved. Then I noticed a leg sticking out through the hole, then another, and the legs scrambled to get out of the cocoon. It came out more and more, and I saw a wet butterfly. When all six legs scrambled out, the back jumped out, too, and the butterfly crawled out and stopped. When it dried it was white; it straightened its wings, flew away, circled around, and alighted on the window.
Two days later the butterfly on the window-sill laid eggs in a row, and stuck them fast. The eggs were yellow. Twenty-five butterflies laid eggs. I collected five thousand eggs. The following year I raised more worms, and had more silk spun.
