natives. The principle of compulsory labor was established forever; and, even to this day, the Indian of Mexico remains the bondsman he was doomed to become in the sixteenth century.
Between the years 1540 and 1542, an expedition was undertaken for the subjugation of an important nation which it was alleged existed far to the north of Mexico. A Franciscan missionary, Marcos de Naza, reported that he had discovered, north of Sonora, a rich and powerful people inhabiting a realm known as Quivara, or the seven cities, whose capital, Cibola, was quite as civilized as an European city. After the report had reached and been considered in Spain, it was determined to send an armed force to this region in order to explore, and if possible to reduce the Quivarans to the Spanish yoke. Mendoza had designed to entrust this expedition to Pedro de Alvarado, after having refused Cortéz permission to lead the adventurers,—a task which he had demanded as his right. But when all the troops were enlisted, Alvarado had not yet reached Mexico from Guatemala, and, accordingly, the viceroy despatched Vasquez de Coronado, at the head of the enterprise. At the same time he fitted out another expedition, with two ships, under the orders of Francisco Alarcon, who was to make a reconnoisance of the coast as far as the thirty-sixth degree, and, after having frequently visited the shores, he was, in that latitude to meet the forces sent by land.
Coronado set forth from Culiacan, with three hundred and fifty Spaniards and eight hundred Indians, and, after reaching the source of the Gila, passed the mountains to the Rio del Norte. He wintered twice in the region now called New Mexico, explored it thoroughly from north to south, and then, striking off to the north east, crossed the mountains and wandering eastwardly as far north as the fortieth degree of latitude, he unfortunately found neither Quivara nor gold. A few wretched ruins of Indian villages were all the discoveries made by these hardy pioneers, and thus the enchanted kingdom eluded the grasp of Spain forever. The troop of strangers and Indians soon became disorganized and disbanded; nor was Alarcon more successful by sea than Coronado by land. His vessels explored the shores of the Pacific carefully, but they found no wealthy cities to plunder, nor could the sailors hear of any from the Indians with whom they held intercourse.
In 1546, a desolating pestilence swept over the land, destroying, according to some writers, eight hundred thousand Indians, and, according to others, five-sixths of the whole population. It lasted for about six months; and, at this period, a projected insurrection
