Why not make up some neat attractive cases, each containing a little collection illustrating the four stages of the growth of this insect?

Do not make the mistake of getting too many eggs. An ounce does not seem like very much, but the well-grown worms from an ounce of eggs ought to have at least seventy-fiv

Chop some young, tender mulberry leaves very fine. Scatter a thin layer of these bits over the cloth and lightly lay it over the hatching eggs. No sooner do the young silkworms become aware of the presence of their favourite vegetable than they make their way to it, coming up through the holes of the bobinet as easily as "rolling off a log." They are tiny creatures. Eight of them laid end t

They will not need to search long for a place to mount and spin in safety and security their cocoon of shining silvery silk.

Wonderful happenings must have been going on inside to make a winged moth out of that naked caterpillar. Something left in the cocoon rattles when you shake it.
