But reflection showed him a less hazardous way of making an effort to reach the boat. The sharks’ fins described a semi-circle only, as had been the case of his single attendant during the night, and he thought that the shoalness of the water prevented their going further than they did, in a south-easterly direction, which was that of the boat. He well knew that a shark required sufficient water to sink beneath its prey, ere it made its swoop, and that it uniformly turned on its back, and struck upward whenever it gave one of its voracious bites. This was owing to the greater length of its upper than of its lower jaw, and Mulford had heard it was a physical necessity of its formation. Right or wrong, he determined to act on this theory, and began at once to wade along the part of the reef that his enemies seemed unwilling to approach.

Had our young mate a weapon of any sort larger than his knife, he would have felt greater confidence in his success. As it was, however, he drew that knife, and was prepared to sell his life dearly should a foe assail him. No sooner was his step heard in the water, than the whole group of sharks were set in violent motion, glancing past, and frequently quite near him, as if aware their intended prey was about to escape. Had the water deepened much, Harry would have returned at once, for a conflict with such numbers would have been hopeless; but it did not; on the contrary, it shoaled again, after a very short distance at which it had been waist deep; and Mulford found himself wading over a long, broad surface of rock, and that directly toward the boat, through water that seldom rose above his knees, and which, occasionally, scarce covered his feet. There was no absolutely naked rock near him, but there seemed to be acres of that which might be almost said to be awash. Amid the greedy throng that endeavored to accompany him, the mate even fancied he recognised the enormous fins of his old companion, who sailed to and fro in the crowd in a stately manner, as if merely a curious looker on of his own movements. It was the smaller, and probably the younger sharks, that betrayed the greatest hardihood and voracity. One or two of these made fierce swoops toward Harry, as if bent on having him at every hazard; but they invariably glided off when they found their customary mode of attack resisted by the shoalness of the water.

Our young mate got ahead but slowly, being obliged to pay a cautious attention to the movements of his escort. Sometimes he was compelled to wade up to his arms in order to cross narrow places, that he might get on portions of the rock that were nearly bare; and once he was actually compelled to swim eight or ten yards. Nevertheless, he did get on, and after an hour of this sort of work, he found himself within a hundred yards of the boat, which lay grounded near a low piece of naked rock, but separated from it by a channel of deep water, into which all the sharks rushed in a body, as if expressly to cut off his escape. Mulford now paused to take breath, and to consider what ought to be done. On the spot where he stood he was quite safe, though ancle deep in the sea, the shallow water extending to a considerable distance on all sides of him, with the single exception of the channel in his front. He stood on the very verge of that channel, and could see in the pellucid element before him, that it was deep enough to float a vessel of some size.

To venture into the midst of twenty sharks required desperation, and Harry was not yet reduced to that. He had been so busy in making his way to the point where he stood as to have no leisure to look for the wreck; but he now turned his eyes in quest of that all interesting object. He saw the shawl fluttering in the breeze, and that was all he could see. Tier had contrived to keep it flying as a signal where he was to be found, but the hull of the schooner had sunk so low in the water that they who were seated on its keel were not visible even at the short distance which now separated them from Mulford. Encouraged by this signal, and animated by the revived hope of still saving his companions, Harry turned toward the channel, half inclined to face every danger rather than to wait any longer. At that moment the fins were all gliding along the channel from him, and in the same direction. Some object drew the sharks away in a body, and the young mate let himself easily into the water, and swam as noiselessly as he could toward the boat.

It was a fearful trial, but Mulford felt that every thing depended on his success. Stimulated by his motive, and strengthened by the food and water taken an hour before, never had he shown so much skill and power in the water. In an incredibly short period he was half way across the channel, still swimming strong and unharmed. A few strokes more sent him so near the boat that hope took full possession of his soul, and he shouted in exultation. That indiscreet but natural cry, uttered so near the surface of the sea, turned every shark upon him, as the pack springs at the fox in view. Mulford was conscious of the folly of his cry the instant it escaped him, and involuntarily he turned his head to note the effect on his enemies. Every fin was gliding toward him—a dark array of swift and furious foes. Ten thousand bayonets, leveled in their line, could not have been one-half as terrible, and the efforts of the young man became nearly frantic. But strong as he was, and ready in the element, what is the movement of a man in the water compared to that of a vigorous and voracious fish? Mulford could see those fins coming on like a tempest, and he had just given up all hope, and was feeling his flesh creep with terror, when his foot hit the rock. Giving himself an onward plunge, he threw his body upward toward the boat, and into so much shoaler water, at least a dozen feet by that single effort. Recovering his legs as soon as possible, he turned to look behind him. The water seemed alive with fins, each pair gliding back and forth, as the bull-dog bounds in front of the ox’s muzzle. Just then a light-colored object glanced past the young man, so near as almost to touch him. It was a shark that had actually turned on its back to seize its prey, and was only prevented from succeeding by being driven from the line of its course by hitting the slimy rock, over which it was compelled to make its plunge. The momentum with which it came on, added to the inclination of the rock, forced the head and half of the body of this terrible assailant into the air, giving the intended victim an opportunity of seeing from what a fate he had escaped. Mulford avoided this fish without much trouble, however, and the next instant he threw himself into the boat, on the bottom of which he lay panting with the violence of his exertions, and unable to move under the reaction which now came over his system.

The mate lay in the bottom of the boat, exhausted and unable to rise, for several minutes; during that space he devoutly returned thanks to God for his escape, and bethought him of the course he was next to pursue, in order to effect the rescue of his companions. The boat was larger than common. It was also well equipped—a mast and sail lying along with the oars, on its thwarts. The rock placed Harry to windward of the wreck, and by the time he felt sufficiently revived to rise and look about him, his plan of proceeding was fully arranged in his own mind. Among other things that he saw, as he still lay in the bottom of the boat, was a breaker which he knew contained fresh water, and a bread-bag. These were provisions that it was customary for the men to make, when employed on boat duty; and the articles had been left where he now saw them, in the hurry of the movements, as the brig quitted the islets.

Harry rose the instant he felt his strength returning. Striking the breaker with his foot, and feeling the basket with a hand, he ascertained that the one held its water, and the other its bread. This was immense relief for by this time the sufferings of the party on the wreck must be returning with redoubled force. The mate then stepped the mast, and fitted the sprit to the sail, knowing that the latter would be seen fluttering in the wind by those on the wreck, and carry joy to their hearts. After this considerate act, he began to examine into the position of the boat. It was still aground, having been left by the tide; but the water had already risen several inches, and by placing himself on a gunwale, so as to bring the boat on its bilge, and pushing with an oar, he soon got it into deep water. It only remained to haul aft the sheet, and right the helm, to be standing through the channel, at a rate that promised a speedy deliverance to his friends, and most of all, to Rose.

Mulford glanced past the rocks and shoals, attended by the whole company of the sharks. They moved before, behind, and on each side of him, as if unwilling to abandon their prey, even after he had got beyond the limits of their power to do him harm. It was not an easy thing to manage the boat in that narrow and crooked channel, with no other guide for the courses than the eye, and it required so much of the mate’s vigilance to keep clear of the sharp angles of the rocks, that he could not once cast his eyes aside, to look for the fluttering shawl, which now composed the standing signal of the wreck. At length the boat shot through the last passage of the reef, and issued into open water. Mulford knew that he must come out half a mile at least to leeward of his object, and, without even raising his head, he flattened in the sheet, put his helm down, and luffed close to the wind. Then, and then only, did he venture to look around him.

Our mate felt his heart leap toward his mouth, as he observed the present state of the wreck. It was dead to windward of him, in the first place, and it seemed to be entirely submerged. He saw the shawl fluttering as before; for Tier had fastened one corner to a button-hole of his own jacket, and another to the dress of Biddy, leaving the part which might be called the fly, to rise at moments almost perpendicularly in the air, in a way to render it visible at some distance. He saw also the heads and the bodies of those on the schooner’s bottom, but to him they appeared to be standing in, or on, the water. The distance may have contributed a little to this appearance, but no doubt remained that so much air had escaped from the hold of the vessel, as to permit it to sink altogether beneath the surface of the sea. It was time, indeed, to proceed to the relief of the sufferers.

Notwithstanding the boat sailed particularly fast, and worked beautifully, it could not equal the impatience of Mulford to get on. Passing away to the north-east a sufficient distance, as he thought, to weather on the wreck, the young man tacked at last, and had the happiness to see that every foot he proceeded was now in a direct line toward Rose. It was only while tacking he perceived that all the fins had disappeared. He felt no doubt that they had deserted him, in order to push for the wreck, which offered a so much larger, and a so much more attainable prey. This increased his feverish desire to get on, the boat seeming to drag, in his eyes, at the very moment it was leaving a wake full of eddies and little whirlpools. The wind was steady, but it seemed to Mulford that the boat was set to leeward of her course by a current, though this could hardly have been the case, as the wreck, the sole mark of his progress, would have had at least as great a drift as the boat. At length Mulford—to him it appeared to be an age; in truth it was after a run of about twenty minutes—came near the goal he so earnestly sought, and got an accurate view of the state of the wreck, and of those on it. The hull of the schooner had, in truth, sunk entirely beneath the surface of the sea; and the party it sustained stood already knee deep in the water. This was sufficiently appalling; but the presence of the sharks, who were crowding around the spot, rendered the whole scene frightful. To the young mate it seemed as if he must still be too late to save Rose from a fate more terrible than drowning, for his boat fell so far to leeward as to compel him to tack once more. As he swept past the wreck, he called out to encourage his friends, begging them to be of good heart for five minutes longer, when he should be able to reach them. Rose held out her arms entreatingly, and the screams of Mrs. Budd and Biddy, which were extorted by the closer and closer approach of the sharks, proclaimed the imminency of the danger they ran, and the importance of not losing a moment of time.
