investigated the metals of the province. It is impossible to conceive of a more rapid development. These things would not have attracted so much attention in Chili or Buenos Ayres, but in an inland province with only the aid of native workmen, the progress was prodigious, and in ten years it might have been one of the most remarkable places in the country; but Facundo's army crushed this promising civilization, and the monk Aldao passed his plough over it and watered the earth with blood for ten years. What could remain?
But the progress of ideas was not entirely stopped with the occupation of Quiroga; the members of the mining society, who emigrated to Chili, there gave themselves up to the study of chemistry, mineralogy, and metallurgy. Godoi Cruz, Correa, Villanueva, Doncel, and many others, looked up all books treating of the subject, and made a large collection of different metals from all parts of South America; they also examined the Chilian archives for information about the mines of Uspallata, and with much labor succeeded in establishing modes of operation by which these mines have become profitable, notwithstanding the scarcity of metal. From that time dates the new and profitable working of the mines of Mendoza. The Argentine miners, not satisfied with these results, scattered themselves throughout Chili, which afforded a rich field for the experiments of their science, and they have accomplished much at Copiapo and other places by the introduction of new machinery and tools.
Godoi Cruz had another object in his researches: he endeavored, by introducing the cultivation of the white mulberry, to solve the problem of the possible
