I was struck in reading this paper with a remark of Dupont on the unprogressive character of the men of the mammoth age, who seem to have made so little advance in the arts of life during the period of their occupation of Europe. Perhaps he makes too great an estimate of the length of their residence, or does not sufficiently consider how long men about their stage of civilisation have remained at the same point in the historic period. Nor does he consider the possibility of the cave men belonging to ruder tribes of a race which may have inhabited better if more perishable residences elsewhere. In any case, all experience shows that to such a people any great advance in the arts could come only by missionary influence from abroad, or by the appearance of some great inventive genius among themselves; and no good fortune of this kind seems to have happened to the Canstadt or Cro-magnon men, or if it did, they rejected their opportunity, as so many others have since done. Still, perhaps, we need not pity them too much. They lived in a young and fresh condition of the earth, enjoyed a vigorous health, and were gifted with rare strength and energy. They were bountifully provided for by nature as to food and clothing, were in slavery to no man, lived in families bound together by ties of affection, and were free to migrate over vast territories according to the exigencies of the seasons. They had some taste in dress and ornaments, and no doubt enjoyed their clever carvings on bone and ivory as much as any modern lovers of art their most finished treasures. A Cro-magnon 'brave,' tall, muscular and graceful in movement, clad in well-dressed skins, ornamented with polished shells and ivory pendants, with a pearly shell helmet, probably decked with feathers, and armed with his flint-headed lance and skull-cracker of reindeer antler handsomely carved, must have been a somewhat noble savage, and he must have rejoiced in the chase of the mammoth, the rhinoceros, the bison, and the wild horse and reindeer, and in launching his curiously-constructed harpoons against the salmon and other larger fish that haunted the rivers.
