Of the numbers who volunteered he selected thirty-nine in all, among whom was a physician, a ship's carpenter, a cooper, a tailor, and a gunner; the command being given to Diego de Arana, notary and alguazil of the armament, with Pedro Gutierrez and Rodrigo de Escobedo as his lieutenants, directing them to obtain all the information in their power. He charged the garrison to be especially circumspect in their intercourse with the natives,--to treat them with gentleness and justice,--to be highly discreet in their conduct towards the Indian females, and, moreover, not to scatter themselves, or on any account stray beyond the friendly territory of Guacanagari. On the 2nd of January, 1493, Columbus bade farewell to the generous cacique and his chieftains, commending those he left behind to their care. To impress the Indians with an idea of the warlike prowess of the white man, after a banquet he had given at his house, he ordered them to engage in mock fights with swords, bucklers, crossbows, arquebuses, and cannon. Guacanagari shed tears as he parted with Columbus, who, returning on board, two days afterwards set sail, the garrison on shore answering the cheers of their comrades who were about to return to their native land. The ship, being towed out of the harbour, they stood to the eastward, but were detained for two days by a contrary wind. On the 6th, a seaman aloft cried out that he saw the _Pinta_. The certainty that he was right cheered the heart of the Admiral and his crew. In a short time she approached, and, as the wind was contrary, Columbus put back to a little bay west of Monte Cristo, where he was followed by the _Pinta_. Pinzon endeavoured to excuse himself, but Columbus discovered that he had purposely separated, and had gone to Hispaniola, where he had remained trading with the natives; collecting a considerable quantity of gold, the greater part of which he retained, and the rest divided among the men to secure his secret. Columbus, however, knowing the number of friends the Pinzons had on board, repressed his indignation; but so much was his confidence in his confederates impaired, that, instead of continuing his explorations, as he hoped to have done when he first saw the _Pinta_, he resolved at once to sail for Spain. While obtaining wood and water for the voyage at a river flowing into the bay, so much gold was perceived in the sand at its mouth that the name of Rio del Oro, or the Golden River, was given to it. At present it is called the Santiago. Turtles of large size were found here, and, as a proof how so sagacious a man as Columbus might deceive himself, he states that he here saw three mermaids, who were very far from lovely, although they had traces of human countenances. They were undoubtedly manatees or sea-cows. Putting into the river where Pinzon had been trading, some of the natives complained that he had violently carried off four men and two girls to be sold as slaves in Spain.
