Large quantities of lac and tussur silk are gathered in the hilly tract.
There are indigo factories, and other industries include the weaving of tussur silk and the making of coarse glass.
The principal products are rice, oil-seeds, lac, tussur silk, horns, hides, wax and a little iron.
On this account the fibres of tussur or tussore silk tend to split up into fine fibrillae under the various preparatory processes in manufacturing, and its riband structure is the cause of the glassy lustre peculiar to the woven and finished fibres.
The natural colour of tussur silk is a greyish fawn, and that shade it was found impossible to discharge by any of the ordinary bleaching agents, so as to obtain a basis for light and delicate dyes.
