the breed being first selected and set apart on hurdles, in a dry and airy situation. The next care, is to destroy the vitality of the chrysalides in those balls which are to be reeled. The most approved method of performing this, is to fill large earthen vessels with cocoons, in layers, throwing in one-fortieth part of their weight of salt upon each layer, covering the whole with large dry leaves resembling those of the water-lilly, and then closely stopping the mouths of the vessels. In reeling their silk the Chinese separate the thick and dark from the long and glittering white cocoons, as the produce of the former is inferior.
We are indebted to Dr. Ure for the two following articles (extracted from the Journal of the Asiatic Society, for January, 1837), on wild silk-worms. The first article is from the pen of Thomas Hugon, a resident of Nowgong, and relates to wild silk-worms of Assam.
"The Assamese select for breeding, such cocoons only as have been begun to be formed in the largest number on the same day, usually the second or third after the commencement; those which contain males being distinguishable by a more pointed end. They are put in a closed basket suspended from the roof; the moths, as they come forth, having room to move about, at the expiration of a day, the females (known only by their large body) are taken out, and tied to small wisps of thatching-straw, selected always from over the hearth, its darkened color being thought more acceptable to the insect. If out of a batch, there should be but few males; the wisps with the females tied to them are exposed outside at night; and the males thrown away in the neighborhood, find their way to them. These wisps are hung upon a string tied across the roof, to keep them from vermin. The eggs laid after the first three days, are said to produce weak worms. The wisps are taken out morning and evening, and exposed to the sun, and in ten days after being laid, a few of them are hatched. The wisps being then hung up to the tree, the young worms find their way to the leaves. The ant, whose bite is fatal to the worm in its early stages, is destroyed by rubbing the trunk of the tree with molasses, and tying dead fish and toads to it, to
