men, for the same number of months, mounted on horse instead of sailing in ships, would have slain not forty, but forty thousand and more buffaloes; a fact that, if need were, could be statistically stated.

Nor, considered aright, does it seem any argument in favour of the gradual extinction of the Sperm Whale, for example, that in former years (the latter part of the last century, say) these Leviathans, in small pods, were encountered much oftener than at present, and, in consequence, the voyages were not so prolonged, and were also much more remunerative. Because, as has been elsewhere noticed, those whales, influenced by some views to safety, now swim the seas in immense caravans, so that to a large degree the scattered solitaries, yokes, and pods, and schools of other days are now aggregated into vast but widely separated, unfrequent armies.
