seems
the conceit, that because the so-called whale-bone whales no longer
haunt many grounds in former years abounding with them, hence that
species also is declining. For they are only being driven from
promontory to cape; and if one coast is no longer enlivened with
their jets, then, be sure, some other and remoter strand has been very
recently startled by the unfamiliar spectacle.

Furthermore: concerning these last mentioned Leviathans, they have two
firm fortresses, which, in all human probability, will for ever remain
impregnable. And as upon the invasion of their valleys, the frosty Swiss
have retreated to their mountains; so, hunted from the savannas and
glades of the middle seas, the whale-bone whales can at last resort to
their Polar citadels, and diving under the ultimate glassy barriers and
walls there, come up among icy fields and floes; and in a charmed circle
of everlasting December, bid defiance to all pursuit from man.

But as perhaps fifty of these whale-bone whales are harpooned for one
cachalot, some philosophers of the forecastle have concluded that this
positive havoc has already very seriously diminished their battalions.
But though for some time past a number of these whales, not less than
13,000, have been annually slain on the nor'-west coast by the Americans
alone; yet there are considerations which render even this circumstance
of little or no account as an opposing argument in this matter.

Natural as it is to be somewhat incredulous concerning the populousness
of the more enormous creatures of the globe, yet what shall we say to
Harto, the historian of Goa, when he tells us that at one hunting the
King of Siam took 4,000 elephants; that in those regions elephants are
numerous as droves of cattle in the temperate climes. And there seems no
reason to doubt that if these elephants, which have now been hunted for
thousands of years, by Semiramis, by Porus, by Hannibal, and by all the
successive monarchs of the East--if they still survive there in great
numbers, much more may the great whale outlast all hunting, since he
has a pasture to expatiate in, which is precisely twice as large as all
Asia, both Americas, Europe and Africa, New Holland, and all the Isles
of the sea combined.

Moreover: we are to consider, that from the presumed great longevity
of whales, their probably attaining the age of a century and more,
therefore at any one period of time, several distinct adult generations
must
