stone hammers, of which many specimens have been found. Sometimes hollows were cut or ground out in the hammering-pebbles (Fig. 1), in order to secure a firmer grip for the fingers.

The manner in which such a pebble could be used for the work was demonstrated to an Englishman some time ago by an Indian arrow-maker in California. The long and narrow barbs in the fine arrow-heads (Fig. 2) and saw-teeth (Fig. 3) were obtained probably by the pressure of a bone tool, such as is still used by some American tribes. Holes were bored, where needed, by twirling a stick, hard pressed upon, against the spot where the perforation was to be. It took a long time, but primitive men had time. Most of the tools were only chipped, while others were polished or ground. The grindstone was usually a suitable block of sandstone, or else a thick piece of the same material. One of these pieces, which has been worn down in the middle by use, is represented by Fig. 4. Handles, if the instruments were provided with them, were inserted into

holes bored by the tedious process which we have mentioned, or were attached in grooves by splitting the end of a stick and binding it around by cords. Clumsy implements these, even at the best, but some beautiful works remain that were executed with them; and a Danish gentleman recently, for experiment, had some trees felled and all the work necessary for building a small
