The principal objects found in these caves, and the rock-shelters are worked flakes, scrapers, cores, awls, lance-heads, cutters, hammers, and mortar-stones. These works, though unpolished, are but little ruder than those of the Esquimaux or the North American Indian. _Belgian Caverns._--Under the auspices of the Belgian government M. Edward Dupont examined more than twenty caves on the banks of the Lesse, in the province of Namur. Among these were four, in which occurred numerous traces of the reindeer-man, namely, Trou du Frontal, Trou Rosette, Trou des Nutons, and Trou de Chaleux. The cavern Trou de Frontal was a place of burial, and similar to the cave of Aurignac. The mouth of the cave was closed by a slab of sandstone, and within were the remains of fourteen human beings belonging to persons of various ages, and some of them to infants scarcely a year old. In front of the cave was an esplanade, where were celebrated the funeral feasts, and which was marked by hearth-stone, traces of fire, flint-knives, bones of animals, shells, etc. The human bones were intermixed with a considerable number of the bones of the reindeer and other animals, as well as the different kinds of implements. Among the remains were two perfect human skulls, in a good state of preservation. The bones were discovered in a state of great confusion, which M. Dupont thinks was caused by the disturbance of water. Sir John Lubbock regards the disturbance of the bones as due to foxes and badgers.[65] Immediately above this cave is the Trou Rosette, in which the bones of three persons were found, mingled with those of the reindeer and beaver. It also contained fragments of a blackish kind of pottery, which were hollowed out in rough grooves and hardened by fire. Dupont is of opinion that the three men were crushed to death by masses of rock at the time of the inundation of the valley of the Lesse. In the Trou des Nutons, situated one hundred and sixty-four feet above the Lesse, were found a great many bones of the reindeer, wild bull, and many other species. In the cave, indiscriminately mixed up with these bones, were one hundred and fifty worked reindeer horns, knuckle-bones of the goat, polished on both sides, a whistle made from the tibia of a goat, fragments of very coarse pottery, and fire-hearths.
