The Ocean Waifs: A Story of Adventure on Land and Sea. Reid Mayne
a long time there was supposed to be only one, or at most two, species of the Exocetus; but it is now certain there are several – perhaps as many as half a dozen – distinct from each other. They are all much alike in their habits, – differing only in size, colour, and such like circumstances.
Naturalists disagree as to the character of their flight. Some assert that it is only a leap, and this is the prevailing opinion. Their reason for regarding it thus is, that while the fish is in the air there cannot be observed any movement of the wings (pectoral fins); and, moreover, after reaching the height to which it attains on its first spring, it cannot afterwards rise higher, but gradually sinks lower till it drops suddenly back into the water.
This reasoning is neither clear nor conclusive. A similar power of suspending themselves in the air, without motion of the wings is well-known to belong to many birds, – as the vulture, the albatross, the petrels, and others. Besides, it is difficult to conceive of a leap twenty feet high and two hundred yards long; for the flight of the Exocetus has been observed to be carried to this extent, and even farther. It is probable that the movement partakes both of the nature of leaping and flying: that it is first begun by a spring up out of the water, – a power possessed by most other kinds of fish, – and that the impulse thus obtained is continued by the spread fins acting on the air after the fashion of parachutes. It is known that the fish can greatly lighten the specific gravity of its body by the inflation of its “swim-bladder,” which, when perfectly extended, occupies nearly the entire cavity of its abdomen. In addition to this, there is a membrane in the mouth which can be inflated through the gills. These two reservoirs are capable of containing a considerable volume of air; and as the fish has the power of filling or emptying them at will, they no doubt play an important part in the mechanism of its aerial movement.
One thing is certain, that the flying-fish can turn while in the air, – that is, diverge slightly from the direction first taken; and this would seem to argue a capacity something more than that of a mere spring or leap. Besides, the wings make a perceptible noise, – a sort of rustling, – often distinctly heard; and they have been seen to open and close while the creature is in the air.
A shoal of flying-fish might easily be mistaken for a flock of white birds, though their rapid movements, and the glistening sheen of their scales – especially when the sun is shining – usually disclose their true character. They are at all times a favourite spectacle, and with all observers, – the old “salt” who has seen them a thousand times, and the young sailor on his maiden voyage, who beholds them for the first time in his life. Many an hour of ennui occurring to the ship-traveller, as he sits upon the poop, restlessly scanning the monotonous surface of the sea, has been brought to a cheerful termination by the appearance of a shoal of flying-fish suddenly sparkling up out of the bosom of the deep.
The flying-fish appear to be the most persecuted of all creatures. It is to avoid their enemies under water that they take fin and mount into the air; but the old proverb, “out of the frying-pan into the fire,” is but too applicable in their case, for in their endeavours to escape from the jaws of dolphins, albicores, bonitos, and other petty tyrants of the sea, they rush into the beaks of gannets, boobies, albatrosses, and other petty tyrants of the sky.
Much sympathy has been felt – or at all events expressed – for these pretty and apparently innocent little victims. But, alas! our sympathy receives a sad shock, when it becomes known that the flying-fish is himself one of the petty tyrants of the ocean, – being, like his near congener, the pike, a most ruthless little destroyer and devourer of any fish small enough to go down his gullet.
Besides the two genera of flying-fish above described, there are certain other marine animals which are gifted with a similar power of sustaining themselves for some seconds in the air. They are often seen in the Pacific and Indian oceans, rising out of the water in shoals, just like the Exoceti: and, like them, endeavouring to escape from the albicores and bonitos that incessantly pursue them. These creatures are not fish in the true sense of the word, but “molluscs,” of the genus Loligo; and the name given to them by the whalers of the Pacific is that of “Flying Squid.”

A Cheering Cloud
The particular species of flying-fish that had fallen into the clutches of the two starving castaways upon the raft was the Exocetus evolans, or “Spanish flying-fish” of mariners, – a well-known inhabitant of the warmer latitudes of the Atlantic. Its body was of a steel-blue, olive and silvery white underneath, with its large pectoral fins (its wings) of a powdered grey colour. It was one of the largest of its kind, being rather over twelve inches in length, and nearly a pound in weight.
Of course, it afforded but a very slight meal for two hungry stomachs, – such as were those of Ben Brace and his boy companion. Still it helped to strengthen them a little; and its opportune arrival upon the raft – which they could not help regarding as providential – had the further effect of rendering them for a time more cheerful and hopeful.
It is not necessary to say that they ate the creature without cooking it; and although under ordinary circumstances this might be regarded as a hardship, neither was at that moment in the mood to be squeamish. They thought the dish dainty enough. It was its quantity – not the quality – that failed to give satisfaction.
Indeed the flying-fish is (when cooked, of course) one of the most delicious of morsels, – a good deal resembling the common herring when caught freshly, and dressed in a proper manner.
It seemed, however, as if the partial relief from hunger only aggravated the kindred appetite from which the occupants of the raft had already begun to suffer. Perhaps the salt-water, mingled with the saline juices of the fish, aided in producing this effect. In any case, it was not long after they had eaten the Exocetus before both felt thirst in its very keenest agony.
Extreme thirst, under any circumstances, is painful to endure; but under no conditions is it so excruciating as in the midst of the ocean. The sight of water which you may not drink, – the very proximity of that element, – so near that you may touch it, and yet as useless to the assuaging of thirst as if it was the parched dust of the desert, – increases rather than alleviates the appetite. It is to no purpose, that you dip your fingers into the briny flood, and endeavour to cool your lips and tongue by taking it into the mouth. To swallow it is still worse. You might as well think to allay thirst by drinking liquid fire. The momentary moistening of the mouth and tongue is succeeded by an almost instantaneous parching of the salivary glands, which only glow with redoubled ardour.
Ben Brace knew this well enough; and once or twice that little William lifted the sea-water on his palm and applied it to his lips, the sailor cautioned him to desist, saying that it would do him more harm than good.
In one of his pockets Ben chanced to have a leaden bullet, which he gave the boy, telling him to keep it in his mouth and occasionally to chew it. By this means the secretion of the saliva was promoted; and although it was but slight, the sufferer obtained a little relief.
Ben himself held the axe to his lips, and partly by pressing his tongue against the iron, and partly by gnawing the angle of the blade, endeavoured to produce the same effect.
It was but a poor means of assuaging that fearful thirst that was now the sole object of their thoughts, – it might be said their only sensation, – for all other feelings, both of pleasure or pain, had become overpowered by this one. On food they no longer reflected, though still hungry; but the appetite of hunger, even when keenest, is far less painful than that of thirst. The former weakens the frame, so that the nervous system becomes dulled, and less sensible of the affliction it is enduring; whereas the latter may exist to its extremest degree, while the body is in full strength and vigour, and therefore more capable of feeling pain.
They suffered for several hours, almost all the time in silence. The words of cheer which the sailor had addressed to his youthful comrade were now only heard occasionally, and at long intervals, and when heard were spoken in a tone that proclaimed their utterance to be merely mechanical, and that he who gave tongue to them had but slight hope. Little as remained, however, he would rise from time to time to his feet, and stand for a while scanning the
