He saw another peak of the mainland to the northwest, which was the peninsula of Paria, and to which Columbus, taking it to be another island, gave the name of Isla de Gracia. Between him and this land lay a narrow channel through which a mighty current was flowing—that press of waters which, sweeping across the Atlantic from Africa, enters the Caribbean Sea, sprays round the Gulf of Mexico, and turns north again in the current known as the Gulf Stream. While his ships were anchored at the entrance to this channel and Columbus was wondering how he should cross it, a mighty flood of water suddenly came down with a roar, sending a great surging wave in front of it. The vessels were lifted up as though by magic; two of them dragged their anchors from the bottom, and the other one broke her cable. This flood was probably caused by a sudden flush of fresh water from one of the many mouths of the Orinoco; but to Columbus, who had no thought of rivers in his mind, it was very alarming. Apparently, however, there was nothing for it but to get through the channel, and having sent boats on in front to take soundings and see that there was clear water he eventually piloted his little squadron through, with his heart in his mouth and his eyes fixed on the swinging eddies and surging circles of the channel. Once beyond it he was in the smooth water of the Gulf of Paria. He followed the westerly coast of Trinidad to the north until he came to a second channel narrower than the first, through which the current boiled with still greater violence, and to which he gave the name of Dragon’s Mouth. This is the channel between the northwesterly point of Trinidad and the eastern promontory of Paria. Columbus now began to be bewildered, for he discovered that the water over the ship’s side was fresh water, and he could not make out where it came from. Thinking that the peninsula of Paria was an island, and not wishing to attempt the dangerous passage of the Dragon’s Mouth, he decided to coast along the southern shore of the land opposite, hoping to be able to turn north round its western extremity.
