This people were said to have possessed a good knowledge of agriculture, and were well instructed in many useful mechanic arts. They mixed gold and copper, and were experts in working these metals. For a period of four hundred years they occupied the territory of Mexico or Anahuac; but secession, and the attendant evils of war, pestilence, and famine, greatly reduced their numbers, and the race disappeared from the land to give place to their successors, the Aztecs, who also emigrated from the North. Remnants of the Toltec race are said to have migrated still farther south, and to have spread over Central America; and the remarkable correspondence of dates inclines us to the belief that the famous Manco Capac, whom the Peruvians worshipped as the founder of their empire, may have been a wanderer from that once happy, but then unfortunate people. The useful arts, which he made known to the semi-barbarous people among whom he settled, instead of originating in the great luminary of the day, and being brought to earth by a "child of the Sun," as they were taught, are far more likely to have been cultivated by the Toltecs in the days of their prosperity, and, on the dissolution of their government, transmitted by those who, fearing the result, had fled and taken refuge with the credulous Peruvians. Whether the stupendous ruins of temples found at Mitla, Palenque, and Uxmal were the work of the Toltecs or the Aztecs, is immaterial. It is sufficient for the purposes of this paper to show that a people inhabited Mexico prior to and at the time of the Conquest, who were far in advance of the roving tribes of Indians that subsisted in the more northern and eastern portions of North America.
