land. But I should not much wonder if, in the darkness of that early hour of the morning, the shock was after all caused by an unseen whale vertically bumping the hull from beneath.

I might proceed with several more examples, one way or another known to me, of the great power and malice at times of the sperm whale. In more than one instance, he has been known, not only to chase the assailing boats back to their ships, but to pursue the ship itself, and long withstand all the lances hurled at him from its decks. The English ship Pusie Hall can tell a story on that head; and, as for his strength, let me say, that there have been examples where the lines attached to a running sperm whale have, in a calm, been transferred to the ship, and secured there; the whale towing her great hull through the water, as a horse walks off with a cart.
