whale can only live by inhaling the disengaged air in the open atmosphere. Wherefore the necessity for his periodical visits to the upper world. But he cannot in any degree breathe through his mouth, for, in his ordinary attitude, the Sperm Whale's mouth is buried at least eight feet beneath the surface; and what is still more, his windpipe has no connection with his mouth. No, he breathes through his spiracle alone; and this is on the top of his head.

If I say, that in any creature breathing is only a function indispensable to vitality, inasmuch as it withdraws from the air a certain element, which being subsequently brought into contact with the blood imparts to the blood its vivifying principle, I do not think I shall err; though I may possibly use some superfluous scientific words. Assume it, and it follows that if all the blood in a man could be aerated with one breath, he might then seal up his nostrils and not fetch another for a considerable time. That is to say, he would then live without breathing. Anomalous as it may seem, this is precisely the case with the whale, who systematically lives, by intervals, his full hour and more (when at the bottom) without drawing a single breath, or so much as in any way inhaling a particle of air; for, remember, he has no gills. How is this? Between his ribs and on each side of his spine he is supplied with a remarkable involved Cretan labyrinth of vermicelli-like vessels, which vessels, when he quits the surface, are completely distended with oxygenated blood. So that for an hour or more, a thousand fathoms in the sea, he carries a surplus stock of vitality in him, just as the camel crossing the waterless desert carries a surplus supply of drink for future use in its four supplementary stomachs. The anatomical fact of this labyrinth is indisputable; and that the supposition founded upon it is reasonable and true, seems the more cogent to me, when I consider the otherwise inexplicable obstinacy of that leviathan in having his spoutings out, as the fishermen phrase it. This is what I mean. If unmolested, upon rising to the surface, the Sperm Whale will continue there for a period of time exactly uniform with all his other unmolested risings. Say he stays eleven minutes, and jets seventy times, that is, respires seventy breaths; then whenever he rises again, he will be sure to have his seventy breaths over again, to a minute. Now, if after he fetches a few breaths you alarm him, so that he sounds, he will be always dodging up again to make

good his regular allowance of air. And not till those seventy breaths are told, will he finally go down to stay out his full term below. Remark, however, that in different individuals these rates are different; but in any one they are alike. Now, why should the whale thus insist upon having his spoutings out, unless it be to replenish his reservoir of air, ere descending for good? How obvious is it, too, that this necessity for the whale's rising exposes him to all the fatal hazards of the chase. For not by hook or by net could this vast leviathan be caught, when sailing a thousand fathoms beneath the sunlight. Not so much thy skill, then, O hunter, as the great necessities that strike the victory to thee!

In man, breathing is incessantly going on—one breath only serving for two or three pulsations; so that whatever other business he has to attend to, waking or sleeping, breathe he must or die he will. But the Sperm Whale only breathes about one seventh or Sunday of his time.

It has been said that the whale only breathes through his spout-hole; if it could truthfully be added that his spouts are mixed with water, then I opine we should be furnished with the reason why his sense of smell seems obliterated in him; for the only thing about him that at all answers to his nose is that identical spout-hole; and being so clogged with two elements, it could not be expected to have the power of smelling. But owing to the mystery of the spout— whether it be water or whether it be vapour—no absolute certainty can as yet be arrived at on this head. Sure it is, nevertheless that the Sperm Whale has no proper olfactories. But what does he want of them? No roses, nor violets, no Cologne-water in the sea.

Furthermore, as his windpipe solely opens into the tube of his spouting canal, and as that long canal—like the grand Erie Canal—is furnished with a sort of locks (that open and shut) for the downward retention of air or the upward exclusion of water, therefore the whale has no voice; unless you insult him by saying, that when he so strangely rumbles, he talks through his nose. But then again, what has the whale to say? Seldom have I known any profound being that had anything to say to this world, unless forced to stammer out something by way of getting a living. Oh! happy that the world is such an excellent listener!

Now, the spouting canal of the Sperm Whale, chiefly intended as it is for the conveyance of air, and for several

feet laid along, horizontally, just beneath the upper surface of his head, and a little to one side; this curious canal is very much like a gas-pipe laid down in a city on one side of a street. But the question returns whether this gas-pipe is also a water-pipe; in other words, whether the spout of the Sperm Whale is the mere vapour of the exhaled breath, or whether that exhaled breath is mixed with water taken in at the mouth, and discharged through the spiracle. It is certain that the mouth indirectly communicates with the spouting canal; but it cannot be proved that this is for the purpose of discharging water through the spiracle. Because the greatest necessity for so doing would seem to be, when in feeding he accidentally takes in water. But the Sperm Whale's food is far beneath the surface, and there he cannot spout even if he would. Besides, if you regard him very closely, and time him with your watch, you will find that when unmolested, there is an undeviating rhyme between the periods of his jets and the ordinary periods of respiration. But why pester one with all this reasoning on the subject? Speak out! You have seen him spout; then declare what the spout is; can you not tell water from air? My dear sir, in this world it is not so easy to settle these plain things. I have ever found your plain things the knottiest of all. And as for this whale spout, you might almost stand in it, and yet be undecided as to what it is precisely.

The central body of it is hidden in the snowy sparkling mist enveloping it; and how can you certainly tell whether any water falls from it, when, always, when you are close enough to a whale to get a close view of his spout, he is in a prodigious commotion, the water cascading all around him. And if at such times you should think that you really perceived drops of moisture in the spout, how do you know that they are not merely condensed from its vapour; or how do you know that they are not those identical drops superficially lodged in the spout-hole fissure, which is countersunk into the summit of the whale's head? For even when tranquilly swimming through the mid-day sea in a calm, with his elevated hump sun-dried as a dromedary's in the desert; even then, the whale always carries a small basin of water on his head, as under a blazing sun you will sometimes see a cavity in a rock filled up with rain.

Nor is it at all prudent for the hunter to be over-curious touching the precise nature of the whale spout. It will not do for him to be peering into it, and putting his face in

ft. You cannot go with your pitcher to this fountain and fill it, and bring it away. For even when coming into slight contact with the outer, vapoury shreds of the jet, which will often happen, your skin will feverishly smart, from the acridness of the thing so touching it. And I. know one, who coming into still closer contact with the spout, whether with some scientific object in view, or otherwise, I cannot say, the skin peeled off from his cheek and arm. Wherefore, among whalemen, the spout is deemed poisonous; they try to evade it. Another thing; I have heard it said, and I do not much doubt it, that if the jet is fairly spouted into your eyes, it will blind you. The wisest thing the investigator can do then, it seems to me, is to let this deadly spout alone.

Still, we can hypothesize, even if we cannot prove and establish. My hypothesis is this: that the spout is nothing but mist. And besides other reasons, to this conclusion I am impelled, by considerations touching the great inherent dignity and sublimity of the Sperm Whale; I account him no common, shallow being, inasmuch as it is an undisputed fact that he is never found on soundings, or near shores; all other whales sometimes are. He is both ponderous and profound. And I am convinced that from the heads of all ponderous profound beings, such as Plato, Pyrrho, the Devil, Jupiter, Dante, and so on, there always goes up a certain semi-visible steam, while in the act of thinking deep thoughts. While composing a little treatise on Eternity, I had the curiosity to place a mirror before me; and ere long saw reflected there, a curious involved worming and undulation in the atmosphere over my head. The invariable moisture of my hair, while plunged in deep thought, after six cups of hot tea in my thin shingled attic, of an August noon; this seems an additional argument for the above supposition.

And how nobly it raises our conceit of the mighty, misty monster, to behold him solemnly sailing through a calm tropical sea; his vast, mild head overhung by a canopy of vapour, engendered by his incommunicable contemplations, and that vapour—as you will sometimes see it—glorified by a rainbow, as if Heaven itself had put its seal upon his thoughts. For, d'ye see, rainbows do not visit the clear air; they only irradiate vapour. And so, through all the thick mists of the dim doubts in my mind, divine intuitions now and then shoot, enkindling my fog with a heavenly

ray. And for this I thank God; for all have doubts; many deny; but doubts or denials, few along with them, have intuitions. Doubts of all things earthly, and intuitions of some things heavenly; this combination makes neither believer nor infidel, but makes a man who regards them both with equal eye.

CHAPTER LXXXVI.

THE TAIL.

Other poets have warbled the praises of the soft eye of the antelope, and the lovely plumage of the bird that never alights; less celestial, I celebrate a tail.

Reckoning the largest sized Sperm Whale's tail to begin at that point of the trunk where it tapers to about the girth of a man, it comprises upon its upper surface alone, an area of at least fifty square feet. The compact round body of its root expands into two broad, firm, flat palms or flukes, gradually shoaling away to less than an inch in thickness. At the crotch or junction, these flukes slightly overlap, then sideways recede from each other like wings, leaving a wide vacancy between. In no living thing are the lines of beauty more exquisitely defined than in the crescentic. borders of these flukes. At its utmost expansion in the full grown whale, the tail will considerably exceed twenty feet across.

The entire member seems a dense webbed bed of welded sinews; but cut into it, and you find that three distinct strata compose it:—upper, middle, and lower. The fibres in the upper and lower layers, are long and horizontal; those of the middle one, very short, and running crosswise between the outside layers. This triune structure, as much as anything else, imparts power to the tail. To the student of old Roman walls, the middle layer will furnish a curious parallel to the thin course of tiles always alternating with the stone in those wonderful relics of the antique, and which undoubtedly contribute so much to the great strength of the masonry.

But as if this vast local power in the tendinous tail were not enough, the whole bulk of the leviathan is knit over with a warp and woof of muscular fibres and filaments,
