fruits of the new crop. In the beginning of August the grains are fully formed, though still tender and white; and it is eaten as green corn, now called "elote." In September the maize is ripe, and is gathered when dry, and stowed away, generally over the rooms of the natives. A second crop is often sown in December. Maize is very prolific, bearing a hundredfold, and ripening in April. From the most ancient times, maize has been the principal food of the inhabitants of the western side of tropical America. On the coast of Peru, Darwin found heads of it,* along with eighteen species of marine shells, in a raised beach eighty-five feet above the level of the sea (* "Geological Observations in South America" 1846 page 49 and "Animals and Plants under Domestication" volume 1 page 320.); and in the same country it has been found in tombs apparently more ancient than the earliest times of the Incas.* (*Von Tschudi "Travels in Peru" English edition page 177.) In Mexico it was known from the earliest times of which we have any record, in the picture writings of the Toltecs; and that ancient people carried it with them in all their wanderings. In Central America the stone grinders, with which they bruised it down, are almost invariably found in the ancient graves, having been buried with the ashes of the dead, as an indispensable article for their outfit for another world. When Florida and Louisiana were first discovered, the native Indian tribes all cultivated maize as their staple food; and throughout Yucatan, Mexico, and all the western side of Central America, and through Peru to Chili, it was, and still is, the main sustenance of the Indians. The people that cultivated it were all more or less advanced in civilisation; they were settled in towns; their traders travelled from one country to another with their wares; they were of a docile and tractable disposition, easily frightened into submission. It is likely that these maize-eating peoples belonged to closely affiliated races. In the West India Islands they occupied most of Cuba and Hayti; but from Porto Rico southwards the islands were peopled by the warlike Caribs, who harassed the more civilised tribes to the north. From Cape Gracias a Dios southward, the eastern coast of America was peopled on its first discovery by much ruder tribes, who did not grow maize, but made bread from the roots of the mandioca (Manihot aipim); and still in British Guiana, on the Lower Amazon, and in north-eastern Brazil, farina made from the roots of the mandioca is the staple food. Maize has been introduced by the Portuguese, but it has no native name, and is used mostly for feeding cattle and fowls, scarcely at all for the food of the people. This fundamental difference in the food of the indigenes points to a great distinction between the peoples to which I shall have in the sequel to revert. In the West India Islands, Cuba and Hayti seem to have been peopled from Yucatan, and Florida, Porto Rico, and all the
