Novel material for percussion caps.
--David Magee, of Fredericksburg, Va., has succeeded in making a very excellent article of caps out of leather and paper. He was in Richmond Saturday, examining the machinery for making copper caps, so as to model his after the same pattern. The scrap leather of which Mr. Magee has thus far made his caps, are pressed into shape while wet, are then allowed to dry, and are then filled, as copper caps are, with the detonating substance. --Both the leather and paper caps are as effective as the regular copper caps. A sample was exhibited at this office on Saturday. They do not make so powerful a report as the copper cap, but are just as certain in their effects. The discoverer of this singular war material thinks he has discovered a way to make both the leather and paper impervious to water.
