This put an end to treasure-seeking on the Amazon, but the search for "El Dorado" had been going on and was still continued along the banks of the Orinoco. The first attempt to reach the golden city by this river appears to have been made by Pedro de Acosta about the year 1530, but after most of his men had been killed and eaten by the cannibals, he was compelled to abandon his project. After him came Diego de Ordas, the following year, whose expedition became afterwards famous. He, however, found nothing himself, although he went as far as the mouth of the Caroni--it was from one of his men that the "El Dorado" story was gleaned. By some accident the whole of the gunpowder was exploded, and this being attributed to the negligence of the munitioner, Juan Martinez, he was sentenced to be put in a canoe, without paddles or food, and allowed to drift at the mercy of the current. What became of the culprit was not known, but some months afterwards a strange white man was brought by some Indians to Margarita. He was wasted by sickness, naked, and apparently destitute, but, through the kindness of a ship-captain, he got a passage to Porto Rico, and was there placed in a religious house, under the care of some Dominican friars. Here he became worse, but when on the point of death he presented his friends with two gourdsful of gold beads to pay for the repose of his soul; he also declared himself to be Juan Martinez, and told the wonderful story of his adventures. After being cast adrift, the canoe floated down the stream until evening, when it attracted the attention of some Indians, who paddled out from the shore and rescued Martinez from his perilous situation. These were Guianians, who had never before seen a white man, and therefore resolved to take him to their king as a curiosity. He was, however, blind-folded to prevent his seeing the direction they were taking, and led on and on, through forest and over mountain, for fifteen days, until a great city was reached. Arriving here at noon, his bandage was taken off, and Martinez feasted his eyes upon a great plain covered with houses, the roofs of which glittered in the sun as if made of gold. As far as his eye could reach stretched this marvellous assemblage of palaces. In the centre dwelt the great king, but, although the party travelled the whole of that and the next day, they did not reach the palace until evening.
