That the population of Central America (and in this term I include Mexico) was at one time very dense, and had attained to a high degree of civilization, higher even than that of Europe in the time of Columbus, there can be no question; and it is also probable, as I have shown, that they originally belonged to the white race. Dêsirè Charnay, who is now exploring the ruins of Central America, says (North American Review, January, 1881, p. 48), "The Toltecs were fair, robust, and bearded. I have often seen Indians of pure blood with blue eyes." Quetzalcoatl was represented as large, "with a big head and a heavy beard." The same author speaks (page 44) of "the ocean of ruins all around, not inferior in size to those of Egypt." At Teotihuacan he measured one building two thousand feet wide on each side, and fifteen pyramids, each nearly as large in the base as Cheops. "The city is indeed of vast extent ... the whole ground, over a space of five or six miles in diameter, is covered with heaps of ruins--ruins which at first make no impression, so complete is their dilapidation." He asserts the great antiquity of these ruins, because he found the very highways of the ancient city to be composed of broken bricks and pottery, the débris left by earlier populations. "This continent," he says (page 43), "is the land of mysteries; we here enter an infinity whose limits we cannot estimate.... I shall soon have to quit work in this place. The long avenue on which it stands is lined with ruins of public buildings and palaces, forming continuous lines, as in the streets of modern cities. Still, all these edifices and halls were as nothing compared with the vast substructures which strengthened their foundations." We find the strongest resemblances to the works of the ancient European races: the masonry is similar; the cement is the same; the sculptures are alike; both peoples used the arch; in both continents we find bricks, glassware, and even porcelain (North American Review, December, 1880, pp. 524, 525), "with blue figures on a white ground;" also bronze composed of the same elements of copper and tin in like proportions; coins made of copper, round and T-shaped, and even metallic candlesticks.
