The depths of the Central American forests will probably yield some new articles of commerce. In the Olancha there is found hanging from the t*.e a sort of sack, some two feet in depth, which is the nest of a species of silkworm. The silk is woven over the inside of this sack. In 1844, six pounds were sent to England, where it was made into handkerchiefs of excellent quality. A profitable trade in this article might, perhaps, be established, as this material can be gathered in any required quantity. An old Mexican author speaks of wild silk as abundant in the Isthmus of Tehuantepec, and states that the natives were accustomed to gather it for exportation to Spain.—California Paper.
