On their estates the planter, the ranchman, and the mine owner lived like feudal overlords, waited upon by Indian and negro peasants who also tilled the fields, tended the droves, and dug the earth for precious metals and stones. Originally the natives had been forced to work under conditions approximating actual servitude, but gradually the harsher features of this system had given way to a mode of service closely resembling peonage. Paid a pitifully small wage, provided with a hut of reeds or sundried mud and a tiny patch of soil on which to grow a few hills of the corn and beans that were his usual nourishment, the ordinary Indian or half-caste laborer was scarcely more than a beast of burden, a creature in whom civic virtues of a high order were not likely to develop. If he betook himself to the town his possible usefulness lessened in proportion as he fell into drunken or dissolute habits, or lapsed into a state of lazy and vacuous dreaminess, enlivened only by chatter or the rolling of a cigarette. On the other hand, when employed in a capacity where native talent might be tested, he often revealed a power of action which, if properly guided, could be turned to excellent account. As a cowboy, for example, he became a capital horseman, brave, alert, skillful, and daring. Commerce with Portugal and Spain was long confined to yearly fairs and occasional trading fleets that plied between fixed points. But when liberal decrees threw open numerous ports in the mother countries to traffic and the several colonies were given also the privilege of exchanging their products among themselves, the volume of exports and imports increased and gave an impetus to activity which brought a notable release from the torpor and vegetation characterizing earlier days. Yet, even so, communication was difficult and irregular. By sea the distances were great and the vessels slow. Overland the natural obstacles to transportation were so numerous and the methods of conveyance so cumbersome and expensive that the people of one province were practically strangers to their neighbors. Matters of the mind and of the soul were under the guardianship of the Church. More than merely a spiritual mentor, it controlled education and determined in large measure the course of intellectual life. Possessed of vast wealth in lands and revenues, its monasteries and priories, its hospitals and asylums, its residences of ecclesiastics, were the finest buildings in every community, adorned with the masterpieces of sculptors and painters. A village might boast of only a few squalid huts, yet there in the "plaza," or central square, loomed up a massively imposing edifice of worship, its towers pointing heavenward, the sign and symbol of triumphant power.
