<h3>Chapter Ninety One.</h3>
<h4>The insane Swimmer.</h4>
<p>A dozen strokes would have carried him up to the craft; which they could not have hindered him from boarding, except by using some deadly violence. To avoid this, the oars were plied; and the raft rapidly pulled in a contrary direction.</p>
<p>For all this, so swiftly did the maniac make way through the water, that it was just as much as they could do to keep the <i>Catamaran</i> clear of his grasp; and it was only after Ben Brace and Snowball had got fairly bent to their oars, that they could insure themselves against being overtaken. Then became it a chase in which there was no great advantage in speed between the pursued and the pursuer; though what little there might have been was in favour of the former.</p>
<p>How long this singular chase might have continued, it is impossible to say. Perhaps until the lunatic had exhausted his insane strength, and sunk into the sea: since he appeared to have no idea of making an attempt to return to the boat. He never looked round to see how far he was leaving it behind him. On the contrary, he swam straight on, his eyes steadfastly fixed upon the one object that seemed to have possession of his soul,—the Coromantee! That it was of him only he was thinking could be told from his speech,—for even while in the water he continued to utter imprecations on the head of the negro,—his name being every moment mentioned in terms of menace.</p>
<p>The chase could not have lasted much longer,—even had it been permitted to terminate by the exhaustion of the insane swimmer. The supernatural strength of insanity could not forever sustain him; and in due time he would have sunk helplessly to the bottom of the sea.</p>
<p>But this was not the sort of death that Fate had designed for him. A still more violent ending of his life was in store for the unfortunate wretch. Though he himself knew it not, those aboard the <i>Catamaran</i> had now become aware of its approach.</p>
<p>Behind him,—scarce half a cable’s length,—two creatures were seen moving through the water. Horrible-looking creatures they were: for they were hammer-headed sharks! Both were conspicuously seen: for they had risen to the surface, and were swimming with their dark dorsal fins protruded above, and set with all the triangular sharpness of staysails. Although they had not been observed before by those on the <i>Catamaran</i>, they appeared to have been swimming in the proximity of the gig,—on which, beyond doubt, they had been for some time attending.</p>
<p>They were now advancing side by side, in the same direction as the swimmer, and there could be no doubt as to their design. They were evidently in chase of <i>him</i>, with as much eagerness as he was in chase of the <i>Catamaran</i>.</p>
<p>The wretched man neither saw nor thought of them. Even had he seen them it is questionable whether he would have made any attempt to escape from them. They would, in all likelihood, have appeared a part of the fearful phantasmagoria already filling his brain.</p>
<p>In any case he could not have eluded those earnest and eager pursuers,—unless by the intervention of those upon the raft; and even had these wished to succour him, it would have required a most prompt and adroit interference. They <i>did</i> wish it, even became desirous to save him. Their hearts melted within them as they saw the unfortunate man, maniac though he was, in such a situation. Fear him as they might,—and deem him an enemy as they did,—still was he a human being,—one of their own kind,—and their natural instinct of hostility towards those ravenous monsters of the deep had now obliterated that which they might have felt for him about to become their prey.</p>
<p>Risking everything from the encounter which they might expect with a madman, they suspended their oars, and then commenced backing towards him. Even Snowball exerted himself to bring the <i>Catamaran</i> within saving distance of the wretch who, in his insane hatred, was threatening his own destruction.</p>
<p>Their good intentions, however, proved of no avail. The man was destined to destruction. Before they could get near enough to make any effective demonstration in his favour, the sharks had closed upon him. They who would have saved him saw it, and ceased their exertions to become spectators of the tragical catastrophe.</p>
<p>It was a brief affair. The monsters swam up, one on each side of their intended victim, till their uncouth bodies were parallel with his. He saw one of them first, and, with an instinct more true than his dethroned powers of reason, swerved out of the way to avoid it. The effort resulted in placing him within reach of the other, that, suddenly turning upon its side, grasped him between its extended jaws.</p>
<p>The shriek that followed appeared to proceed from only the half of his body; for the other half, completely dissevered, had been already carried off between the terrible teeth of the <i>zygaena</i>.</p>
<p>There was but one cry. There was not time for another, even had there been strength. Before it could have been uttered, the remaining moiety of the madman’s body was seized by the second shark, and borne down into the voiceless abysm of the ocean!</p>
