This house, or fort, has been surrounded by a wall, seven feet thick, and in which enormous stones were used; the beams of pine are said still to exist. In the centre is a keep or mound; the whole has had a ditch about it, and earthen pots, jars, &c. with mirrors of the itzli stone, have been dug up in the neighbourhood. On leaving this spot, they crossed the mountains of Taraumara, and rested three years at Culiacan. When the Aztecas left their native country, they consisted of six tribes, viz. the Mexicans, Tepanecas, Chalcese, Tlahuicas, Tlascans, and Xochimilcans. At Culiacan they constructed the image of the deity Huitzilopochtli, with a throne to carry it on the shoulders of four priests. The Mexicans were deserted by the five other tribes on quitting Culiacan, and journeying with their image, arrived at Tula, the capital which the Toltecans had built, erecting altars at all their resting places on the road. They stayed here, and in the vicinity, twenty years; and in 1216 they came to Zumpanco, a large town in the vale of Anahuac; here they were kindly received, and one of their chief women married Ilhuicatl, the son of the chief; from which marriage the race of Mexican emperors descended. They roamed about the borders of the lake Tezcuco, settling in different places, and at last engaged in wars with the Cachemicas and Acolhuans, and were obliged to take refuge in some islands called Acocolo, in the southern part of the Mexican lakes. Here they existed fifty-two years, in great poverty, and were finally enslaved by the chief of a small state called Colhuacan.
