I
I was puzzled by the phrase, “silkworm-moth eyebrow,” in an old Japanese, or rather Chinese proverb:—The silkworm-moth eyebrow of a woman is the axe that cuts down the wisdom of man. So I went to my friend Niimi, who keeps silkworms, to ask for an explanation.
“Is it possible,” he exclaimed, “that you never saw a silkworm-moth? The silkworm-moth has very beautiful eyebrows.”
“Eyebrows?” I queried, in astonishment. “Well, call them what you like,” returned Niimi;—“the poets call them eyebrows…. Wait a moment, and I will show you.”
He left the guest-room, and presently returned with a white paper-fan, on which a silkworm-moth was sleepily reposing.
“We always reserve a few for breeding,” he said;—“this one is just out of the cocoon. It cannot fly, of course: none of them can fly…. Now look at the eyebrows.”
I looked, and saw that the antennae, very short and feathery, were so arched back over the two jewel-specks of eyes in the velvety head, as to give the appearance of a really handsome pair of eyebrows.
Then Niimi took me to see his worms.
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.
