rising in a lofty elevation, and from pure springs, but plunging steadily down till it pours itself into that Dead Sea from which there is no outlet.” (_b_) Later investigations have rendered it probable that the stone age of some localities was contemporaneous with the bronze and iron ages of others, while certain tribes and nations, instead of making progress from one to the other, were never, so far back as we can trace them, without the knowledge and use of the metals. It is to be observed, moreover, that even without such knowledge and use man is not necessarily a barbarian, though he may be a child. On the question whether the arts of civilization can be lost, see Arthur Mitchell, Past in the Present, 219: Rude art is often the debasement of a higher, instead of being the earlier; the rudest art in a nation may coëxist with the highest; cave-life may accompany high civilization. Illustrations from modern Scotland, where burial of a cock for epilepsy, and sacrifice of a bull, were until very recently extant. Certain arts have unquestionably been lost, as glass-making and iron-working in Assyria (see Mivart, referred to above). The most ancient men do not appear to have been inferior to the latest, either physically or intellectually. Rawlinson: “The explorers who have dug deep into the Mesopotamian mounds, and have ransacked the tombs of Egypt, have come upon no certain traces of savage man in those regions which a wide-spread tradition makes the cradle of the human race.” The Tyrolese peasants show that a rude people may be moral, and a very simple people may be highly intelligent. See Southall, Recent Origin of Man, 386-449; Schliemann, Troy and her Remains, 274. Mason, Origins of Invention, 110, 124, 128—“There is no evidence that a stone age ever existed in some regions. In Africa, Canada, and perhaps Michigan, the metal age was as old as the stone age.” An illustration of the mathematical powers of the savage is given by Rev. A. E. Hunt in an account of the native arithmetic of Murray Islands, Torres Straits. “Netat” (one) and “neis” (two) are the only numerals, higher numbers being described by combinations of these, as “neis-netat” for three, “neis-i-neis” for four, etc., or by reference to one of the fingers, elbows or other parts of the body. A total of thirty-one could be counted by the latter method. Beyond this all numbers were “many,” as this was the limit reached in counting before the introduction of English numerals, now in general use in the islands.
