Among the stone implements flint flakes were incredibly numerous, and the number of chips scattered about as well as the blocks of flint from which they had been struck, proved that they had been made on the spot; most of these flakes were notched by use (Fig. 106). Instruments with the ends carefully rounded off (Fig. 107) were also abundant, and from their analogy with similar instruments used by the Eskimos, there can be but little doubt that they were intended for the preparation of skins (compare Fig. 107 with Fig. 124). The ends of some were chipped to a point for insertion into a handle, while others rounded at both ends were probably used freely in the hand. In the cave of Moustier oval implements were met with, resembling those figured from the caverns of Kent’s Hole and Wookey (Figs. 84 and 97). The spear, javelin, and arrow-heads of flint presented two modes of attachment to the shaft, the base of some being squared off with a notch above for the ligature (as in Fig. 108), while in others (Fig. 109) it tapered off into a point intended for insertion. This latter form has been obtained also in Kent’s Hole. The bone needles are carefully smoothed, and were pierced with a neatly-made eye (Fig. 110) by means of pointed flakes which were found along with them, and the use of which M. Lartet demonstrated by experiment. They had been sawn out of the compact metacarpals and tarsals of the reindeer[224] and the horse, and subsequently rounded on fragments of sandstone, the grooves of which fitted them. In this, therefore, we have not merely the evidence that the hunters were in the habit of sewing, but also we have vividly brought before us the very method by which their needles were manufactured. They were probably used for sewing skins together, the tendon of a reindeer forming the thread, as among the modern Eskimos. [Illustration: FIGS. 111, 112.--Harpoons of Antler, La Madelaine. (Lartet and Christy.) FIGS. 113, 114.--Arrow-heads, Gorge d’Enfer. (Broca.) FIG. 115.--Bone Awl, Gorge d’Enfer (1/1). (Broca.)] The heads of arrows and lances are made principally out of reindeer antler, and are barbed, the barbs generally being grooved, and carved on both sides of the axis (Figs. 111, 112, 113); but in some cases, as in Fig. 114, the barbs are only on one side. Many bones and antlers are variously carved into shapes for which it is impossible to assign a definite use. Fig. 115 is a bone awl. [Illustration: FIG. 116.--Carved Handle of Reindeer Antler (1/2).
