and thirty-nine quintals of quicksilver, for which he paid a hundred and fifty-nine thousand two hundred and forty-one dollars.
In June, 1778, the mineral deposits of Hostotipaquillo, in the province of Guadalajara, now Jalisco, were discovered, and promised the most extraordinary returns of wealth. In the following year, the valuable mines of Catorce, were accidentally found by a soldier whilst searching for a lost horse. All these discoveries and beneficial labors induced Bucareli to recommend the mineral interests of New Spain particularly to the sovereign, and various persons were charged to explore the country, for the discovery of quicksilver mines, which it was alleged existed in Mexico. The extraction of quicksilver from American mines had hitherto been prohibited by Spain, but the fear of wars, which might prevent its importation from abroad, and consequently, destroy the increasing mineral industry of the nation, induced the court to send Don Raphael Heling and Don Antonio Posada, with several subordinates, who formerly wrought in the mines of Almaden, to examine the deposits at Talchapa and others in the neighborhood of Ajuchitlan, in October, 1778, under the direction of padre Alzate. But this reconnoisance proved unavailing at that time, inasmuch as the explorers found no veins or deposits which repaid the cost and labor of working.
At this epoch the Spanish government began to manifest a desire to propagate information in its American possessions. There is a gleam of intellectual dawn seen in a royal order of Charles, in 1776, commanding educated ecclesiastics to devote themselves to the study of Mexican antiquities, mineralogy, metallurgy, geology, and fossils. This decree was directed to the clergy because his majesty, perhaps justly supposed, that they were the only persons who possessed any knowledge of natural sciences, whilst the rest of his American subjects were in the most profound ignorance.
