Inasmuch, then, as this Leviathan comes floundering down upon us from the head-waters of the Eternities, it may be fitly inquired, whether, in the long course of his generations, he has not degenerated from the original bulk of his sires.

But upon investigation we find, that not only are the whales of the present day superior in magnitude to those whose fossil remains are found in the Tertiary system (embracing a distinct geological period prior to man), but of the whales found in that Tertiary system, those belonging to its latter formations exceed in size those of its earlier ones.

Of all the pre-adamite whales yet exhumed, by far the largest is the Alabama one mentioned in the last chapter, and that was less than seventy feet in length in the skeleton. Whereas, we have already seen, that the tape-measure gives seventy-two feet for the skeleton of a large sized modern whale. And I have heard, on whalemen's authority, that Sperm Whales have been captured near a hundred feet long at the time of capture.

But may it not be, that while the whales of the present hour are an advance in magnitude upon those of all previous geological periods; may it not be, that since Adam's time they have degenerated?

Assuredly, we must conclude so, if we are to credit the accounts of such gentlemen as Pliny, and the ancient naturalists generally. For Pliny tells us of Whales that embraced acres of living bulk, and Aldrovandus of others which measured eight hundred feet in length-- Rope Walks and Thames Tunnels of Whales! And even in the days of Banks and Solander, Cooke's naturalists, we find a Danish member of the Academy of Sciences setting down certain Iceland Whales (reydan-siskur, or Wrinkled Bellies) at one hundred and twenty yards; that is, three hundred and sixty feet. And Lacepede, the French naturalist, in his elaborate history of whales, in the very beginning of his work (page 3), sets down the Right Whale at one hundred metres, three hundred and twenty-eight feet. And this work was published so late as A.D. 1825.

But will any whaleman believe these stories? No. The whale of to-day is as big as his ancestors in Pliny's time. And if ever I go where Pliny is, I, a whaleman (more than he was), will make bold to tell him so. Because I cannot understand how it is, that while the Egyptian mummies that were buried thousands of years before even Pliny was born, do not measure so much in their coffins as a modern Kentuckian in his socks; and while the cattle and other animals sculptured on the oldest Egyptian and Nineveh tablets, by the relative proportions in which they are drawn, just as plainly prove that the high-bred, stall-fed, prize cattle of Smithfield, not only equal, but far exceed in magnitude the fattest of Pharaoh's fat kine; in the face of all this, I will not admit that of all animals the whale alone should have degenerated.

But still another inquiry remains; one often agitated by the more recondite Nantucketers. Whether owing to the almost omniscient look-outs at the mast-heads of the whaleships, now penetrating even through Behring's straits, and into the remotest secret drawers and lockers of the world; and the thousand harpoons and lances darted along all continental coasts; the moot point is, whether Leviathan can long endure so wide a chase, and so remorseless a havoc; whether he must not at last be exterminated from the waters, and the last whale, like the last man, smoke his last pipe, and then himself evaporate in the final puff.

Comparing the humped herds of whales with the humped herds of buffalo, which, not forty years ago, overspread by tens of thousands the prairies of Illinois and Missouri, and shook their iron manes and scowled with their thunder-clotted brows upon the sites of populous river-capitals, where now the polite broker sells you land at a dollar an inch; in such a comparison an irresistible argument would seem furnished, to show that the hunted whale cannot now escape speedy extinction.

But you must look at this matter in every light. Though so short a period ago--not a good lifetime--the census of the buffalo in Illinois exceeded the census of men now in London, and though at the present day not one horn or hoof of them remains in all that region; and though the cause of this wondrous extermination was the spear of man; yet the far different nature of the whale-hunt peremptorily forbids so inglorious an end to the Leviathan.
