The whole next day I watched it for a long time. I knew that worms moulted several times, because they grew up and found it close in their old hide, and so put on a new one.
My friend and I watched it by turns. In the evening my friend called out:

With my nail I no doubt disturbed the new shirt, for, though the worm crawled out, it soon died.
The other worms I did not touch. Аll of them came out of their shirts in the same manner; only a few died, and nearly all came out safely, though they struggled hard for a long time.
