captain redwood and the irishman were horrified at the sight that had passed under their eyes. so, too, were the children, who had both started up from their reclining attitude, and looked over the side of the boat. even the impassive malay, all his life used to stirring scenes, in which blood was often shed, could not look down into those depths, disturbed by such a tragical occurrence, without having aroused within him a sensation of horror.

all of them recoiled back into the boat, staggering down upon their seats. one alone remained standing, and with an expression upon his face as if he was desirous of again beholding the sight. it was not a look that betrayed pleasure, but one grim and ghastly, yet strong and steady, as if it penetrated the profoundest depths of the ocean. it was the look of the insane sailor.

if his companions had still held any lingering before a finger could touch him he had made the fatal spring doubts about his insanity, it was sufficient to dispel them. it was the true stare of the maniac.

it was not long continued. scarce had they resumed their seats when the man, once more elevating his arms in the air, uttered another startling shriek, if possible louder and wilder than before. he had stepped upon one of the boat seats, and stood with body bent, half leaning over the gunwale, in the attitude of a diver about to make his headlong plunge.

there could be no mistaking his intention to leap overboard, for his comrades could see that his muscles were strained to the effort.

all three—the captain, murtagh, and the malay—suddenly rose again, and leant forward to lay hold on him. they were too late. before a finger could touch him he had made the fatal spring; and the next moment he was beneath the surface of the sea!

none of them felt strong enough to leap after and try to save him. in all probability, the effort would have been idle, and worse; for the mad fancy that seemed urging him to self-destruction might still influence his mind, and carry another victim into the same vortex with himself. restrained by this thought, they stood up in the boat, and watched for his coming up again.

he did so at length, but a good distance off. a breeze had been gradually springing up, and during his dive the pinnace had made some way, by drifting before it. when his head was again seen above the curling water, he was nearly a hundred yards to windward of the boat. he was not so far off as to prevent them from reading the expression upon his face, now turned toward them. it had become changed, as if by magic. the wild look of insanity was gone, and in its place was one almost equally wild, though plainly was it an expression of fear, or indeed terror. the immersion into the cold, deep sea, had told upon his fevered brain, producing a quick reaction of reason; and his cries for help, now in piteous tones sent back to the boat, showed that he understood the peril in which he had placed himself.

they were not unheeded. murtagh and the malay rushed, or rather tottered, to the oars; while the captain threw himself into the stern, and took hold of the tiller-ropes.

in an instant the pinnace was headed round, and moving through the water in the direction of the swimmer; who, on his side, swam toward them, though evidently with feeble stroke. there seemed not much doubt of their being able to pick him up. the only danger thought of by any of them was the zygaena; but they hoped the shark might be still occupied with its late prey, and not seeking another victim. there might be another shark, or many more; but for some time past one only had been seen in the neighbourhood of the boat; the shark, as they supposed, which had but recently devoured the dead body of the sailor. trusting to this conjecture, they plied the oars with all the little strength left in their arms. still, notwithstanding their feeble efforts, and the impediment of pulling against the wind, they were nearing the unfortunate man, surely, if slowly.

they had got over half the distance; less than half a cable’s length was now between the boat and the struggling swimmer. not a shark was to be seen on the water, nor beneath it—no fish of any kind—nothing whatever in the sea. only, in the sky above, a large bird, whose long scimitar-shaped wings and grand curving beak told them what it was—an albatross. it was the great albatross of the indian seas, with an extent of wing beyond that of the largest eagle, and almost equalling the spread of the south american condor. (note 1.)

they scarce looked at it, or even glanced above, they were looking below for the zygaena—scanning the surface of the water around them, or with their eyes keenly bent, endeavouring to penetrate its indigo depths in search of the monstrous form.

no shark in sight. all seemed well; and despite the piteous appeals of the swimmer, now toiling with feebler stroke, and scarce having power to sustain himself they in the pinnace felt sure of being able to rescue him.

less than a quarter cable’s length lay between. the boat, urged on by the oars, was still lessening the distance. five minutes more, and they would be close to their comrade, and lift him over the gunwale.

still no zygaena in sight—no shark of any kind.

“poor fellow! he seems quite cured; we shall be able to save him.”

it was captain redwood who thus spoke. the irishman was about making a little hopeful rejoinder, when his speech was cut short by a cry from saloo, who had suspended his stroke, as if paralysed by some sudden despair.

the malay, who, as well as murtagh, had been sitting with his back toward the swimmer, had slewed himself round with a quick jerk, that told of some surprise. the movement was caused by a shadow flitting over the boat; something was passing rapidly through the air above. it had caught the attention of the others, who, on hearing saloo’s cry, looked up along with him.

they saw only the albatross moving athwart the sky, no longer slow sailing as before, but with the swift-cutting flight of a falcon pouncing down upon its prey. it seemed descending not in a straight line, but in an acute parabolic curve, like a thunderbolt or some aerolite projected toward the surface of the sea. but the bird, with a whirr like the sound of running spindles, was going in a definite direction, the point evidently aimed at being the head of the swimmer!

a strange commingled shout arose over the ocean, in which several voices bore part. surprise pealed forth from the lips of those in the boat, and terror from the throat of the struggling man, while a hoarse croak from the gullet of the albatross, followed by what appeared a mocking scream of triumph. then quick succeeded a crashing sound, as the sharp heavy beak of the bird broke through the skull of the swimmer, striking him dead, as if by the shot of a six-pounder, and sending his lifeless body down toward the bottom of the sea!

it came not up again—at all events, it was never more seen by his castaway companions; who, dropping the oars in sorrowful despair, allowed the boat to drift away from the fatal spot—in whatever direction the soft-sighing breeze might capriciously carry it.

note 1. the albatross is the largest of the ocean-birds. its wings, when extended, measuring fifteen feet, and its weight sometimes exceeding twenty to twenty-four pounds. the common albatross is the diomedea exulans of naturalists. its plumage, except a few of the wing feathers, is white; its long, hard beak, which is very powerful, is of a pale yellow colour; and its short, webbed feet are flesh coloured. it is frequently met with in the southern ocean. the species mentioned in the text is the black-beaked albatross, which frequents the india waters. the albatross is a formidable enemy to the sailor, for if one falls overboard, he will assuredly fall a victim to this powerful bird, unless rescued immediately by his comrades. its cry has some resemblance to that of the pelican; but it will also, when excited, give rent to a noise not unlike the braying of an ass. the female makes a rude nest of earth on the sea-shore, and deposits therein her solitary egg, which is about four inches long, white, and spotted at the larger end.
