Bank Notes of Silk.

Bank notes made of silk of a par" ticUlar shade that will baffle the banknote foTger are now possible. As is known, most of the expert banknote forgers use photography to obtain their best results; but a recent invention makes it possible to manufacture silk of a particular shade that cannot possibly be photographed. Discovered by a woman, this invention is a new process of waterpropfing fabrics without rubber and dyeing them in the same operation. Linen, cotton or other materials to be treats ed by this process are placed white into one end of the machine and brought out at the other end a few minutes later colored, .waterproofed, and dry. Fabrics so produced, the inventor maintains, can be used in hundreds of trades, from aeroplane building to banknote making.
