comes from the worm, contains a strong gum, which would be dissolved by the showers of water dashed against the trees, and thus the cocoons, being loosened from the leaves and twigs, would be easily collected. In the subsequent processes, water would be further useful in enabling the women to spin the silk or to wind it upon bobbins.

It may be observed that in this use of water art only follows nature. When the moth is ready to leave its cell, it always softens the extremity of it by emitting a drop of fluid, and thus easily obtains for itself a passage. In the third volume of the Transactions of the Royal Asiatic Society (p. 543.), Colonel Sykes gives the following account of the process by which the moth of the Kolisurra silk-worm liberates itself from confinement. "It discharges from its mouth a liquor, which dissolves or loosens that part of the cocoon adjoining to the cord which attaches it to the branch, causing a hole, and admitting of the passage of the moth. The solvent property of this liquid is very remarkable; for that part of the cocoon, against which it is directed, although previously as hard as a piece of wood, becomes soft and pervious as wetted brown paper."

In the seventh volume of the Linnæan Transactions, is an account by Dr. Roxburgh of the Tusseh silk-worm. Both species are natives of Bengal. The cocoons require to be immersed in cold water before the silk can be obtained from them. In the latter species it is too delicate to be wound from the cocoons, and is therefore spun like cotton. Thus manufactured it is so durable, that the life of one person is seldom sufficient to wear out a garment made of it, and the same piece descends from mother to daughter. (See Chap. VIII. of this Part.)
