other Palæolithic men who have left abundant traces of their presence in the spear-heads, flints, scrapers and other large stone implements which are often found in the gravel deposits of ancient rivers. The Old Stone-workers, as this earliest known race of men is called to distinguish them from Neolithic men, their immeasurably remote descendants or representatives, knew, of course, nothing of the use of metals, and generally fashioned their flint implements or their bone needles in a somewhat rough and unworkmanlike manner. They knew nothing of the art of the weaver, and can therefore have had no other clothing than the skins of beasts. Neither did they ever manufacture anything in the nature of pottery; so that shells and the skulls of animals must have been their only drinking cups. But the relics of their primeval feasts show that they were in all probability not cannibals, and the very few Palæolithic skulls which have been preserved show a type decidedly nobler than some of the backward races of the present day. Curiously enough the men who had made so little advance in the homely industries of life had nevertheless a distinct feeling for graphic art. “By far the most noteworthy objects” in the Palæolithic caves “are the fragments of bone, horn, ivory and stone, which exhibit outlined and even shaded sketches of various animals. These engravings have been made with a sharp-pointed implement, and are often wonderfully characteristic representations of the creatures they portray. The figures are sometimes single; in other cases they are drawn in groups. We find representations of a fish, a seal, an ox, an ibex, the red-deer, the great Irish elk or deer, the bison, the horse, the cave-bear, the rein-deer and the mammoth or woolly elephant.”[1]
