His plans, however, were frustrated by Roldan and Escobar, the delegates of Columbus, and he was compelled to withdraw from the island. On the 5th of February, 1500, he returned, carrying with him to Cadiz an extraordinary number of slaves, from which he realized an enormous sum of money. At the beginning of December, 1499, the same year in which Ojeda set sail on his last voyage, another companion of Columbus, in his first voyage, Vicente Yañez Pinzon, sailed from Palos, was the first to cross the line on the American side of the Atlantic. and on the 20th of January, 1500, discovered Cape St. Augustine, to which he gave the name of Cabo Santa Maria de la Consolacion, whence returning northward he followed the westerly trending coast, and so discovered the mouth of the Amazon, which he named Paricura. Within a month after his departure from Palos, he was followed from the same port and on the same route by Diego de Lepe, who was the first to discover, at the mouth of the Oronoco, by means of a closed vessel, which only opened when it reached the bottom of the water, that, at a depth of eight fathoms and a half, the two lowest fathoms were salt water, but all above was fresh. Lepe also made the observation that beyond Cape St. Augustine, which he doubled, as well as Pinzon, the coast of Brazil trended south-west." _R. H.
