Had the competition and spirit of rivalry been at a lower point among our adventurers than it actually was, greater caution might have been observed. It is just as dangerous to assault a whale that has its young to defend, as to assault most other animals. We know that the most delicate women become heroines in such straits; and nature seems to have given to the whole sex, whether endowed with reason or only with an instinct, the same disposition to die in defence of the helpless creatures that so much depend on their care. But, no one there now thought of the risk he ran, it being the Vineyard against Oyster Pond, one Sea Lion against the other, and, in many instances, pocket against pocket. Roswell, as if disdaining all meaner game, pulled quite through the herd, and laid the bows of his boat directly on the side of the old bull--a hundred-barrel whale, at the very least. No sooner did the enormous creature feel the harpoon, than, throwing its flukes upward, it descended into the depths of the ocean, with a velocity that caused smoke to arise from the chuck through which the line passed. Ordinarily, the movement of a whale is not much faster than an active man can walk; and, when it runs on the surface, its speed seldom exceeds that of a swift vessel under full sail; but, when suddenly startled, with the harpoon in its blubber, the animal is capable of making a prodigious exertion. When struck, it usually 'sounds,' as it is termed, or runs downward, sometimes to the depth of a mile; and it is said that instances have been known in which the fish inflicted great injury on itself, by dashing its head against rocks.
