Clark Wissler, ../../ (1913)
“ In the days of the old flint-lock, tinder was lighted by snapping the lock of the rifle, while a little powder was put in the pan so that the flash might readily ignite the tinder. The placing of tinder around the hole in the fire drill is not essential. What really ignites is the wood dust ground off by the friction, and from this the tinder is ignited. It is true that tinder is sometimes placed beneath the hearth of the fire drill so that the wood dust, as it is ground off, accumulates on it in a little heap, but it is the wood dust that first takes fire. ”
