"But how can we tell? Aren't they all shut up inside the cocoons?" gasped Pierre.

"Oh, it is quite easy," answered Josef. "The female silkworm spins a house which, like an egg, is a little sharper at one end than at the other. We'll choose about the same number of each gender. There is a knack in selecting good cocoons for breeding, and you've got to know lots of things about them. And after we have chosen them there will be the rest of the cocoons to sort. That will require care, too. We cannot do it as experts do, but still we can group them roughly into lots of various kinds. We can get at it to-morrow. I will give you your first lesson. I fancy your mother knows more about it than the rest of us for she has always helped your father do this part of the work."

"It will be fun to learn!" cried Marie. "Won't it, Pierre?"

"I don't believe it will be very hard," sniffed Pierre. "There can't be much choice in cocoons. Most of them look alike, except that some are bigger than others."

Josef regarded the boy a moment and then laughed.

"Don't be too cock-sure of that!" he retorted ironically.
