common silk-worm spins and suspends itself by its thread, long before it begins its cocoon. It appears probable, therefore, that there may have been wild varieties of this creature, or perhaps other species of the same genus, which in the earlier stages of their existence spun threads long enough for use. We ground this conjecture partly on the following passage from Du Halde's History of China[1].
"The province of Chan-tong produces a particular sort of silk, which is found
in great quantities on the trees and in the fields. It is spun and made into a stuff
called Kien-tcheou. This silk is made by little insects that are much like caterpillars. They do not spin an oval or round cocoon, like the silk-worms, but very long threads. These threads, as they are driven about by the winds, hang upon the trees and bushes, and are gathered to make a sort of silk, which is coarser than that made of the silk spun in houses. But these worms are wild, and eat indifferently the leaves of mulberry and other trees. Those who do not understand this silk would take it for unbleached cloth, or a coarse sort of drugget. "The worms, which spin this silk, are of two kinds: the first, much larger and blacker than the common silk-worms, are called Tsouen-kien; the second, being smaller, are named Tiao-kien. The silk of the former is of a reddish gray, that of the latter darker. The stuff made of these materials is between both colors, it is very close, does not fret, is very lasting, washes like linen, and, when it is good, receives no damage by spots, even though oil were to be shed on it. "This stuff is much valued by the Chinese, and it is sometimes as dear as satin or the finest silks. As the Chinese are very skilful at counterfeiting, they make a false sort of Kien-tcheou with the waste of the Tche-kiang silk, which without due inspection might easily be taken for the genuine article." This account affords a remarkable illustration of many of the expressions of the ancient writers, such as "Bombyx pendulus urget opus," Martial; "Per aerem liquando aranearum horoscopis idoneas sedes tendit," Tertullian; "In aranearum morem tenuissima fila deducunt," Servius. In further illustration of the subject, and as tending to show that the Kien-tcheou is manufactured from the thread of a silk-worm, modified in its habits and perhaps in its organization by circumstances, we shall now quote a few passages from a work having the following title: "China; its costume, arts, manufactures, &c., edited from the originals in the cabinet of M. Bertin, with observations by M. Breton. Translated from the French. London, 1812." Vol. iv. p. 55, &c.
