_Clothing._--Clothing also varied according to locality. Where the wild animals were numerous their skins were used--there being no incentive to substitute other material. Coarse material made of fibrous plants had come into use. The lake-dwellers clothed themselves with this material, and completely protected their bodies. They also used sandals for their feet, as these have been found with the usual indications of usage. _Food._--Where wild animals could be obtained they were used, and the marrow of the long bones extracted. To this, fish and birds were added. In Denmark the principal food was the different species of the edible mollusk. In Switzerland a higher order and greater variety of food was used. The meat of the wild animals, birds, and fish was varied with bread made of barley and wheat, and fruit and berries. The meat was not only obtained from the wild animal, but they provided against the uncertainty of the chase by domesticating the boar, ox, sheep, and goat. The horse and dog were domesticated to assist in the chase, but sometimes served for food, probably during a famine. If these people were cannibals, the evidence must rest solely on the human bones discovered at a dolmen near the village of Hammer, Denmark, which had been subjected to the action of fire. They were found together with some flint implements. But this evidence is not sufficient to lead to the conclusion that at the funeral banquets human flesh was used along with the roasted stag. _Arts and Manufactures._--The flint hatchets of the refuse-heaps are generally of an imperfect type; the long knives indicate a considerable amount of skill; the bodkins, spear-heads, and scrapers are but little improved. In the latter part of this epoch, the various kinds of implements, especially in Switzerland, attained to a surprising degree of perfection, in so much so, it is difficult to understand how this was achieved without the use of metal. They were made into various shapes, and with the design of pleasing the eye. Besides the various types of implements common to the different countries, the tribes of Denmark manufactured a drilled hatchet, which is combined in various ways with the hammer. A specimen of this type is represented in Fig. 16, now in the Museum of Copenhagen. It is pierced with a round hole, in which the handle was fixed. The cutting edge describes an arc of a circle, and the other end is wrought into sharp angular edges.
