At length Mark found, to his great delight, that there were four good fathoms of water under the ship's bows, though she still hung abaft. He ascertained this fact by means of Bob Betts, which true-hearted tar stood by him, with a lantern, by swinging which low enough, the marks were seen on the lead-line. Foot by foot the ship now surged ahead, the seas being so much reduced in size and power, by the manner in which they had been broken to windward, as not to lift the vessel more than an inch or two at a time. After waiting patiently a quarter of an hour, Mark believed that the proper time had come, and he gave the order to 'let run.' The seaman stationed at the stopper obeyed, and down went the anchor. It happened, opportunely enough, that the anchor was thus dropped, just as the keel cleared the bottom, and the cable being secured at a short range, after forging ahead far enough to tighten the hitter, the vessel tended. In swinging to her anchor, a roller came down upon her, however; one that had crossed the reef without breaking, and broke on board her. Mark afterwards believed that the rush and weight of this sea, which did no serious harm, frightened the men into the launch, where Hillson was already in person, and that the boat either struck adrift under the power of the roller, or that the painter was imprudently cast off in the confusion of the moment. He had got in as far as the windlass himself, when the sea came aboard; and, as soon as he recovered his sight after the ducking he received, he caught a dim view of the launch, driving off to leeward, on the top of a wave. Hailing was useless, and he stood gazing at the helpless boat until it became lost, like everything else that was a hundred yards from the ship, in the gloom of night. Even then Mark was by no means conscious of the extent of the calamity that had befallen him. It was only when he had visited cabin, steerage and forecastle, and called the crew over by name, that he reached the grave fact that there was no one left on board the Rancocus but Bob Betts and himself!
As Mark did not know what land was to be found to leeward, he naturally enough hoped and expected that the people in both boats might reach the shore, and be recovered in the morning; but he had little expectation of ever seeing Captain Crutchely again. The circumstances, however, afforded him little time to reflect on these things, and he gave his whole attention, for the moment, to the preservation of the ship. Fortunately, the anchor held, and, as the wind, which had never blown very heavily, sensibly began to lessen, Mark was sanguine in the belief it would continue to hold. Captain Crutchely had taken the precaution to have the cable bitted at a short range with a view to keep it, as much as possible, off the bottom; coral being known to cut the hempen cables that were altogether in use, in that day, almost as readily as axes. In consequence of this bit of foresight, the Rancocus lay at a distance of less than forty fathoms from her anchor, which Mark knew had been dropped in four fathoms' water. He now sounded abreast of the main-mast, and ascertained that the ship itself was in nine fathoms. This was cheering intelligence, and when Bob Betts heard it, he gave it as his opinion that all might yet go well with them, could they only recover the six men who had gone to leeward in the jolly-boat. The launch had carried off nine of their crew, which, previously to this night, had consisted of nineteen, all told. This suggestion relieved Mark's mind of a load of care, and he lent himself to the measures necessary to the continued safety of the vessel, with renewed animation and vigour.
