been as yet discovered in Europe; but hammers of stag's horn and detached tines have frequently been found in connection with worked flints, and may have served in their manufacture. I have, moreover, remarked among the worked flints discovered in this country, and especially in Yorkshire, a number of small tools, the ends of which present a blunted, worn, and rounded appearance, as if from attrition against a hard substance. These tools are usually from 2 to 4 inches long, and made from large thick flakes, with the cutting edges removed by chipping; but occasionally, they are carefully finished implements of a pointed oval or a subtriangular section, and sometimes slightly curved longitudinally. Of these, illustrations will be given at a subsequent page. They are usually well adapted for being held in the hand, and I cannot but think that we have in them some of the tools which were used in the preparation of flint arrow-heads and other small instruments. I have tried the experiment with a large flake of flint used as the arrow-flaker, both unmounted and mounted in a wooden handle, and have succeeded in producing with it very passable imitations of ancient arrow-heads, both leaf-shaped and barbed. The flake of flint on which I have operated has been placed against a stop on a flat piece of wood, and when necessary to raise the edge of the flake I have placed a small blocking piece, also of wood, underneath it, and then by pressure of the arrow-flaker upon the edge of the flake, have detached successive splinters until I have reduced it into form. If the tool consists of a rather square-ended flake, one corner may rest upon the table of wood, and the pressure be given by a rocking action, bringing the other corner down upon the flake. In cutting the notches in barbed arrow-heads, this was probably the plan adopted, as I was surprised to find how easily this seemingly difficult part of the process was effected. Serration of the edges may be produced by the same means.
The edges of the arrow-heads made entirely with these flint arrow-flakers are, however, more obtuse and rounded than those of ancient specimens, so that probably these flint tools were used rather for removing slight irregularities in the form than for the main chipping out. This latter process, I find experimentally, can be best performed by means of a piece of stag's horn, used much in the same way as practised by the Eskimos. By supporting the flake of flint which is to be converted into an arrow-head against a wooden stop, and pressing the horn against the edge of the
