The objects found in the sepulchral caves are important, and included a number of arrow-heads with transverse cutting edges. There is no doubt about their use; they have been picked up in black earth, in contact with human bones, the decomposition of the soft parts of which caused them to fall out of the mortal wound they had inflicted. With these arrow-heads were found flint knives, large sloped scrapers, polishers, and bone stilettos, the femora of a ruminant with a pig’s tooth fixed on to each end, hoes made of stag horn, beads and pendants made of bone, shell, schist, quartz, and aragonite, with the teeth of bears, boars, wolves, and foxes, all pierced with holes. Some of the shell anti schist beads were spread upon the surface of the skull, and perhaps formed a net or _résille_, such as that already referred to as found at Baoussé-Roussé. For centuries this occupation of caves continued, offering as they did a shelter that was dry and warm in winter, and cool in summer. Homer tells us that the Cyclops lived on the heights of the mountains and in the depths of the caves,4 and Prometheus says that, like the feeble ant, men dwelt in deep subterranean caves, where the sun never penetrated.5 Whilst the men of the Petit-Morin valley hollowed out caves, or enlarged those made by nature, others took refuge in buts made of dried clay and interlaced branches, or in tents of the skins of the animals they had slain, and, though these fragile dwellings have disappeared, leaving no trace, there yet remain indelible evidences of the presence of many successive generations. Everywhere throughout the world we find heaps of rubbish, consisting chiefly of the shells of mollusca and crustacea, broken bones, flakes of flint, and fragments of stone and bone implements, covering vast areas and often rising to a considerable height.
