course, necessitated the gathering of grass or other material for their food. They also cultivated wheat, barley, flax, and a number of other vegetable products. Their methods of cultivation were no doubt very rude, consisting of a mere scratching of the ground with crooked branches of trees or with simple instruments made of stags' horn; but, nevertheless, they succeeded in getting very good results. Among the relics which they have left are found stones for crushing corn, the grain which they used, and even the very cakes or bread which they made. There are also fruits, such as the apple, pear, nut, etc.; so that the bill of fare of prehistoric man was by no means contemptible. He had fish, game, beef, mutton, pork, bread, and fruit, besides a plentiful supply of water from the lake at his door. He was acquainted with the potter's art, and manufactured earthen vessels of various kinds. He seems to have produced two kinds--a coarser and a finer; the former made from clay mixed with a quantity of grains of stone, and the latter of washed loam. These he ornamented in an elementary fashion with certain lines and marks. Some of the vessels he used have been found with a burnt crust of the porridge which he had been making adhering. As to his clothes, these were probably formed in great part from the skins of wild or domestic animals, but he also used fabrics made from flax, which he had learned to weave, as remains of cloth, twine, rope, etc., are not infrequently found in his dwellings.
