While these orders were being carried out, he despatched his brother, Bartholomew Columbus,--Adelantado, the Spaniards call him, of the island,--with a number of miners and a troop of soldiers, to the gold mines, which had been discovered by the assistance of the natives sixty leagues from Isabella in the direction of Cipangu, As some very ancient pits were found there, the Admiral believed that he had rediscovered in those mines the ancient treasures which, it is stated in the Old Testament, King Solomon of Jerusalem had found in the Persian Gulf. Whether this be true or false is not for me to decide. These mines cover an area of six miles. The miners, in sifting some dry earth gathered at different places, declared that they had found such a great quantity of gold hidden in that earth that a miner could easily collect three drachmas in a day's work. After they had explored that region, the Adelantado and the miners wrote to Columbus acquainting him with their discovery. The ships being then ready, Columbus immediately and with great delight embarked to return to Spain; that is to say, the fifth day of the ides of March in the year 1495.[9] He confided the government of the province with full powers to his brother, the Adelantado, Bartholomew Columbus. [Note 9: Columbus sailed on March 10, 1496.] BOOK V TO CARDINAL LUDOVICO D'ARAGON, NEPHEW OF OUR KING Acting upon the parting counsel of his brother, the Adelantado, Bartholomew Columbus, constructed a blockhouse at the mines, which he called El Dorado,[1] because the labourers discovered gold in the earth with which they were building its walls. It required three months to manufacture the necessary tools for washing and sifting the gold, but famine obliged him to abandon this enterprise before it was terminated. At a place sixty miles farther on, where he and the greater part of his soldiers went, he succeeded in procuring from the islanders a small quantity of the bread they make, to such a bad state were affairs at that time reduced. Unable to prolong his stay, he left ten men at El Dorado, furnishing them with a small part of the bread that remained. He moreover left with them an excellent hunting dog for chasing the game, which I have above said resembles our rabbits, and which are called _utias_; after which he left to return to Concepcion. It was at that time that the tribute from the caique Guarionex and one of his neighbours called Manicavex was due. The Adelantado remained there the whole month of June, and obtained from the caciques, not only the sum total of the tribute, but also provisions necessary to support himself and the 400 men of his escort.
