Mulford felt that he had been providentially rescued from death. His strength had been about to fail him, when he was thus led, unknown to himself, to a spot where his life might yet be possibly prolonged for a few more hours, or days. He had leisure to look about him, and to reflect on what was next to be done. Almost unwittingly, he turned in quest of his terrible companion, in whose voracious mouth he had actually believed himself about to be immolated, a few seconds before. There the two horn-like fins still were, gliding about above the water, and indicating the smallest movement of their formidable owner. The mate observed that they went a short distance ahead of him, describing nearly a semi-circle, and then returned, doing the same thing in his rear, repeating the movements incessantly, keeping always on his right. This convinced him that shoaler water existed on his left hand, and he waded in that direction, until he reached a small spot of naked rock. For a time, at least, he was safe! The fragment of coral on which the mate now stood, was irregular in shape, but might have contained a hundred feet square in superficial measurement, and was so little raised above the level of the water as not to be visible, even by daylight, at the distance of a hundred yards. Mulford found it was perfectly dry, however, an important discovery to him, as by a close calculation he had made of the tides, since quitting the Dry Tortugas, he knew it must be near high water. Could he have even this small portion of bare rock secure, it made him, for the moment, rich as the most extensive landholder living. A considerable quantity of sea-weed had lodged on the rock, and, as most of this was also quite dry, it convinced the young sailor that the place was usually bare. But, though most of this sea-weed was dry, there were portions of the more recent accessions there that still lay in, or quite near to the water, which formed exceptions. In handling these weeds, in order to ascertain the facts, Mulford caught a small shell-fish, and finding it fresh and easy to open, he swallowed it with the eagerness of a famishing man. Never had food proved half so grateful to him as that single swallow of a very palatable testaceous animal. By feeling further, he found several others of the same family, and made quite as large a meal, as, under the circumstances, was probably good for him. Then, grateful for his escape, but overcome by fatigue, he hastily arranged a bed of sea-weed, drew a portion of the plant over his body, to keep him warm, and fell into a deep sleep that lasted for hours.
