of the mines of St. Domingo, which have never been wrought since. It was soon reduced, therefore, to a third; then to a fifth; afterwards to a tenth; and at last to a twentieth part of the gross produce of the gold mines. The tax upon silver continued for a long time to be a fifth of the gross produce. It was reduced to a tenth only in the course of the present century. But the first adventurers do not appear to have been much interested about silver. Nothing less precious than gold seemed worthy of their attention.
All the other enterprizes of the Spaniards in the New World, subsequent to those of Columbus, seem to have been prompted by the same motive. It was the sacred thirst of gold that carried Ovieda, Nicuessa, and Vasco Nugnes de Balboa, to the Isthmus of Darien; that carried Cortes to Mexico, Almagro and Pizarro to Chili and Peru. When those adventurers arrived upon any unknown coast, their first inquiry was always if there was any gold to be found there; and according to the information which they received concerning this particular, they determined either to quit the country or to settle in it.
