Darwin quotes approvingly the opinion of Mr. Bentham ("Hist. Notes Cult. Plants"), "as the result of all the most reliable evidence that none of the Ceralia--wheat, rye, barley, and oats--exist or have existed truly wild in their present state." In the Stone Age of Europe five varieties of wheat and three of barley were cultivated. (Darwin, "Animals and Plants," vol. i., p. 382.) He says that it may be inferred, from the presence in the lake habitations of Switzerland of a variety of wheat known as the Egyptian wheat, and from the nature of the weeds that grew among their crops, "that the lake inhabitants either still kept up commercial intercourse with some southern people, or had originally proceeded as colonists from the south." I should argue that they were colonists from the land where wheat and barley were first domesticated, to wit, Atlantis. And when the Bronze Age came, we find oats and rye making their appearance with the weapons of bronze, together with a peculiar kind of pea. Darwin concludes (Ibid., vol. i., p. 385) that wheat, barley, rye, and oats were either descended from ten or fifteen distinct species, "most of which are now unknown or extinct," or from four or eight species closely resembling our present forms, or so "widely different as to escape identification;" in which latter case, he says, "man must have cultivated the cereals at an enormously remote period," and at that time practised "some degree of selection." Rawlinson ("Ancient Monarchies," vol. i., p. 578) expresses the opinion that the ancient Assyrians possessed the pineapple. "The representation on the monuments is so exact that I can scarcely doubt the pineapple being intended." (See Layard's "Nineveh and Babylon," p. 338.) The pineapple (Bromelia ananassa) is supposed to be of American origin, and unknown to Europe before the time of Columbus; and yet, apart from the revelations of the Assyrian monuments, there has been some dispute upon this point. ("Amer. Cyclop.," vol. xiii., p. 528.) ANCIENT IRISH PIPES It is not even certain that the use of tobacco was not known to the colonists from Atlantis settled in Ireland in an age long prior to Sir Walter Raleigh. Great numbers of pipes have been found in the raths and tumuli of Ireland, which, there is every reason to believe, were placed there by men of the Prehistoric Period. The illustration on p. 63 represents some of the so-called "Danes' pipes" now in the collection of the Royal Irish Academy. The Danes entered Ireland many centuries before the time of Columbus, and if the pipes are theirs, they must have used tobacco, or some substitute for it, at that early period. It is probable, however, that the tumuli of Ireland antedate the Danes thousands of years. ANCIENT INDIAN PIPE, NEW JERSEY
