Other species are found in different parts of Asia. The balance of probabilities seems to incline toward the view that the turbary sheep came into Europe from western and central Asia with other "turbary" forms, that it had been long domesticated, and either here or on its westward migration may have more or less crossed with the descendants of other varieties. The oldest domesticated goats seem to be descended from the Bezoar goat (_Capra ægagrus_), from the mountains of southwestern Asia. The presence of oxen, sheep, and goats is enough to prove that the people must have practised agriculture to some extent to have kept these animals alive through the winter. That they were kept on the platform is shown by the presence of manure in the remains underneath. Whether this was used for fertilizer we do not know, nor their method of cultivating the ground. No agricultural implements have come down to us. "The small-grained, six-rowed barley (_Hordeum hexastichum sanctum_) and the small lake-dwelling wheat (_Triticum vulgare antiquorum_) were the most ancient, most important, and most generally cultivated farinaceous seeds of our country. Next to them come the beardless compact wheat (_T. vulg. compactum muticum_) and the larger six-rowed barley (_Hordeum hexastichum densum_), with the two kinds of millet, the common millet (_Panicum miliaceum_) and the Italian millet (_Setaria italica_). The Egyptian wheat (_Triticum turgidum L._), the two-rowed wheat (emmer, _Triticum dicoccum Schr._), and the one-grained wheat (_Trit. monococcum_) were probably, like the two-rowed barley, only cultivated as experiments in a few places; and the spelt (_Triticum spelta L._), which at present is one of the most important cereals, and the oat (_Avena sativa L._) appeared later, not till the Bronze Age, while rye was entirely unknown among the lake-dwellings of Switzerland."[61] Oats occur in the Bronze period in western, middle, and northern Europe, in the Alpine lake-dwellings, and in the Danish islands. The ancient Egyptians and Hebrews, Indians and Chinese, did not cultivate them; they were raised in Asia Minor and America only since historic times. We remember that wheat and barley are mentioned in the oldest records of the Old Testament--as in Gideon's barley loaf--but rye and oats not at all.
