In 1755,--after founding the Presidio of Horcasitas, in Sonora, designed to restrain the incursions of the Apaches into that province,--the Count Revilla-Gigedo, was recalled, at his own request, from the Mexican viceroyalty in order that he might devote himself to the management of his private property, which had increased enormously, during his government. In the history of Mexican viceroys, this nobleman is celebrated as a speculative and industrious trader. There was no kind of commercial enterprise or profitable traffic in which he did not personally engage. His palace degenerated into an exchange, frequented by all kinds of adventurers, while gaming tables were openly spread out to catch the doubloons of the viceroyal courtiers. The speculations and profits of Revilla-Gigedo enabled him to found _Mayorazgos_ for his sons in Spain, and he was regarded, throughout Europe, as the richest vassal of Ferdinand the VI. His son, who subsequently became a Mexican viceroy, and was the second bearing the family title, labored to blot out the stain which the trading propensities of his father had cast upon his name. He was a model of propriety in every respect; but, whilst he made no open display of anxiety to enrich himself corruptly through official influence or position, he, nevertheless, exhibited the avaricious traits of his father in requiring from his butler, each night an exact account of every cent that was spent during the day, and every dish that was prepared in his kitchen. Notwithstanding the notorious and corrupting habits of the first count, that personage contrived to exercise an extraordinary influence or control over the masses in Mexico. The people feared and respected him; and, upon a certain occasion, when they were roused in the capital and gathered in menacing mobs, this resolute viceroy, whose wild and savage aspect aided the authority of his determined address, rode into the midst of the turbulent assemblage without a soldier in attendance, and immediately dispersed the revolutionists by the mere authority of his presence and command.
