In Niimi’s neighborhood, where there are plenty of mulberrytrees, many families keep silkworms;—the tending and feeding being mostly done by women and children. The worms are kept in large oblong trays, elevated upon light wooden stands about three feet high. It is curious to see hundreds of caterpillars feeding all together in one tray, and to hear the soft papery noise which they make while gnawing their mulberry-leaves. As they approach maturity, the creatures need almost constant attention. At brief intervals some expert visits each tray to inspect progress, picks up the plumpest feeders, and decides, by gently rolling them between forefinger and thumb, which are ready to spin. These are dropped into covered boxes, where they soon swathe themselves out of sight in white floss. A few only of the best are suffered to emerge from their silky sleep,—the selected breeders. They have beautiful wings, but cannot use them. They have mouths, but do not eat. They only pair, lay eggs, and die. For thousands of years their race has been so well-cared for, that it can no longer take any care of itself. It was the evolutional lesson of this latter fact that chiefly occupied me while Niimi and his younger brother (who feeds the worms) were kindly explaining the methods of the industry. They told me curious things about different breeds, and also about a wild variety of silkworm that cannot be domesticated:—it spins splendid silk before turning into a vigorous moth which can use its wings to some purpose. But I fear that I did not act like a person who felt interested in the subject; for, even while I tried to listen, I began to muse. II First of all, I found myself thinking about a delightful revery by M. Anatole France, in which he says that if he had been the Demiurge, he would have put youth at the end of life instead of at the beginning, and would have otherwise so ordered matters that every human being should have three stages of development, somewhat corresponding to those of the lepidoptera. Then it occurred to me that this fantasy was in substance scarcely more than the delicate modification of a most ancient doctrine, common to nearly all the higher forms of religion.
