During the following year Mendoza received despatches from the Emperor in which, after bestowing encomiums for the manifestations of good government which the viceroy had already given, he was directed to pay particular attention to the Indians; and, together with these missives, came a summary of the laws which the Council of the Indies had formed for the welfare of the natives. These benevolent intentions, not only of the sovereign but of the Spanish people also, were made known to the Indians and their caciques, upon an occasion of festivity, by a clergyman who was versed in their language, and, in a similar way, they were disseminated throughout the whole viceroyalty. This year was, moreover, memorable in Mexican annals as that in which the first book, entitled _La Escala de San Juan Climaca_, was published in Mexico, in the establishment of Juan Pablos, having been printed at a press brought to the country by the viceroy Mendoza. Nor was 1536 alone signalized by the first literary issue of the new kingdom; for the first money, as well as the first book came at this time from the Mexican mint. According to Torquemada two hundred thousand dollars were coined in _copper_; but the emission of a circulating medium, in this base metal, was so distasteful to the Mexicans, that it became necessary for the viceroy to use stringent means in order to compel its reception for the ordinary purposes of trade. Between the years 1536 and 1540 the history of the Mexican viceroyalty was uneventful, save in the gradual progressive efforts made not only by Mendoza, but by the Emperor himself, in endeavoring to model and consolidate the Spanish empire on our continent. Schools were established; hospitals were erected; the protection of the Indians, under the apostolic labors of Las Casas was honestly fostered, and every effort appears to have been zealously made to give a permanent and domestic character to the population which found its way rapidly into New Spain. In 1541 the copper coin, of which we have already spoken as being distasteful to the Mexicans, suddenly disappeared altogether from circulation, and it was discovered that the natives had either buried or thrown it into the lake as utterly worthless. The viceroy endeavored to remedy the evil and dispel the popular prejudice by coining _cuartillas_ of silver; but these, from their extreme smallness and the constant risk of loss, were equally unacceptable to the people, who either collected large quantities and melted them into bars, or cast them contemptuously into the water as they had before done with the despised copper.
