Having consulted those persons who were best informed on this subject, obtained leave of the royal Governours, hired men to dig, and purchased cattle to maintain them, solely on the promise of reward, he explored, for some time, the bowels of the earth, but with no success, with great loss, and terrible expense, as it was necessary to convey both wood and water many leagues on the backs of mules. Overwhelmed with debts, which his hopes of discovering gold had led him to contract, this wretched man served to teach others that it is safer to seek for gold on the surface of the earth, than in the subterranean caverns of the Cordoban mountains. And indeed no one, that I know of, from that time forward ever thought of seeking there for mines of gold. A report was spread amongst the common people, that the Indians, before the coming of the Spaniards, had dug gold out of the mountains which surround the city Rioja. But every attempt of the Spaniards to find this noble metal in those mountains was uniformly unsuccessful. That small pieces of gold had been discovered in our times in the mountains near the city of Monte-Video, I was informed by Andonaegui, Governour of Buenos-Ayres. Though the Catholic King was made acquainted with this circumstance, no pains were ever taken to examine and excavate those mountains, it being thought that there was little hope, and perhaps no reality in the matter. Some one reported that amethysts had been found in the river Rosario, near the city of Monte-Video; but I thought that they either were not genuine, or had been brought thither from some other place, as no one was known to have taken the pains to seek for more in the same river.
