Note 1308 — GUNS. GUN-LOCKS.

This kind of stone is not everywhere used for this purpose. In the Tyrol, for example, the hardest ferruginous granite, which consists of corneous, partly irregular and partly polyedral, pieces, is employed as flints, which therefore are called Tyrol flints. In other places, jasper, such as that found in great abundance in Turkey, is formed by grinding, and used in the same manner.
