The wreck was fully half a mile from the rock of the mate, but much nearer to the reef than it had been the previous night. “Could it but ground on the rocks,” thought the young man, “it would be a most blessed event.” The thing was possible, though the first half hour of his observations told him that its drift was in the direction of the open passage so often named, rather than toward the nearest rocks. Still, that drift brought Rose each minute nearer and nearer to himself again. In looking round, however, the young man saw the boat. It was a quarter of a mile distant, with open water between them, apparently grounded on a rock, for it was more within the reef than he was himself. He must have passed it in the dark, and the boat had been left to obey the wind and currents, and to drift to the spot where it then lay.
Mulford shouted aloud when he saw the boat, and at once determined to swim in quest of it, as soon as he had collected a little refreshment from among the sea-weed. On taking a look at his rock by daylight, he saw that its size was quadrupled to the eye by the falling of the tide, and that water was lying in several of the cavities of its uneven surface. At first he supposed this to be sea-water, left by the flood; but, reflecting a moment, he remembered the rain, and hoped it might be possible that one little cavity, containing two or three gallons of the fluid, would turn out to be fresh. Kneeling beside it, he applied his lips in feverish haste, and drank the sweetest draught that had ever passed his lips. Slaking his thirst, which had begun again to be painfully severe, he arose with a heart overflowing with gratitude—could he only get Rose to that narrow and barren rock, it would seem to be an earthly paradise. Mulford next made his scanty, but, all things considered, sufficient meal, drank moderately afterward, and then turned his attention and energies toward the boat, which, though now aground and fast, might soon float on the rising tide, and drift once more beyond his reach. It was his first intention to swim directly for his object; but, just as about to enter the water, he saw with horror the fins of at least a dozen sharks, who were prowling about in the deeper water of the reef, and almost encircling his hold. To throw himself in the midst of such enemies would be madness, and he stopped to reflect, and again to look about him. For the first time that morning, he took a survey of the entire horizon, to see if any thing were in sight; for, hitherto, his thoughts had been too much occupied with Rose and her companions, to remember any thing else. To the northward and westward he distinctly saw the upper sails of a large ship, that was standing on a wind to the northward and eastward. As there was no port to which a vessel of that character would be likely to be bound in the quarter of the Gulf to which such a course would lead, Mulford at once inferred it was the sloop-of-war, which, after having examined the islets, at the Dry Tortugas, and finding them deserted, was beating up, either to go into Key West, or to pass to the southward of the reef again, by the passage through which she had come as lately as the previous day. This was highly encouraging; and could he only get to the boat, and remove the party from the wreck before it sank, there was now every prospect of a final escape.
