There is still, Most Holy Father, a subject which is quite worthy to figure in history, but I would prefer to see it handled by a Cicero or a Livy than by myself. It affords me such astonishment that I feel more embarrassed in my description than a young chicken wrapped in tow. We have said that, according to the Indians, the land separating the north from the south sea can be traversed in six days. I am not a little puzzled both by the number and size of the rivers described, and by the small breadth of that stretch of land; nor do I understand how such large rivers can possibly flow down from these mountains, only three days' march from the sea, and empty into the north ocean. I cannot understand it, for I presume that equally large rivers empty into the south sea. Doubtless the rivers of Uraba are not so important when compared with others, but the Spaniards declare that during the lifetime of Columbus they discovered and have since sailed upon a river the breadth of whose mouth, where it empties into the sea, is not less than one hundred miles. This river is on the borders of Paria, and descends with such force from the high mountains that it overwhelms the sea even at high tide or when it is swept by violent winds, driving back the waves before the fury and weight of its current. The waters of the sea for a large area round about are no longer salt but fresh, and pleasant to the taste. The Indians call this river Maragnon.[6] Other tribes give it the names Mariatambal, Camamoros, or Paricora. In addition to the rivers I have before mentioned, the Darien, Rio Grande, Dobaiba, San Matteo, Veragua, Boiogatti, Lagartos, and Gaira, there are also others which water the country. I wonder, Most Holy Father, what must be the size of these mountain caverns so near the seacoast, and, according to the Indians, so narrow, and what sources they have to enable them to send forth such torrents of water? Several explanations suggest themselves to my mind. [Note 6: Just which river is meant is not clear. The description would seem to fit the Orinoco, but Maragnon is the native name for the Amazon. This last name is given exclusively to the upper part of the river in the Peruvian territory.] The first is the size of the mountains. It is claimed that they are very great and this was the opinion of Columbus, who discovered them. He had also another theory, asserting that the terrestrial paradise was situated on the top of the mountains visible from Paria and Boca de la Sierpe. He ended by convincing himself that this was a fact. If these mountains are so immense, they must contain extensive and gigantic reservoirs. If such be the case, how are these reservoirs supplied with water? Is it true, as many people think, that all fresh waters flow from the sea into the land, where they are forced by the terrible power of the waves into subterranean passages of the earth, just as we see it pour forth from those same channels to flow again into the ocean?
