It is certain that in the month of September, 1570, Philip II. of Spain, purchased this mine of the above-mentioned Amador Cabrera, and that the different processes employed in working it, were immediately undertaken by the superintendant, Don Pedro De Los Rios. The first governor was Don Francisco De Angulo, during whose administration, which lasted five years, from 1571 to 1576, upwards of nine thousand quintals of mercury were extracted[1]. The mine of Huancavelica has continued to be the exclusive property of the crown.
In the year 1735, the political system of its government was changed. It had before been confided to one of the members of the Royal Audience of Lima; but was at length invested in a particular governor, who had nothing in common with his predecessors, except the title of superintendant.
