But it was only the sound they made as they parted the brit which at all reminded one of mowers. Seen from the mastheads, especially when they paused and were stationary for a while, their vast black forms looked more like lifeless masses of rock than anything else. And as in the great hunting countries of India, the stranger at a distance will sometimes pass on the plains recumbent elephants without knowing them to be such, taking them for bare, blackened elevations of the soil; even so, often, with him, who for the first time beholds this species of the leviathans of the sea. And even when recognised at last, their immense magnitude renders it very hard really to believe that such bulky masses of overgrowth can possibly be instinct, in all parts, with the same sort of life that lives in a dog or a horse.
