It was about one bell in the first dog-watch; the weather was fine, the water smooth, the breeze light; and the brig, with little more than bare steerage-way upon her, was laying her course, with squared yards, both clews of her mainsail hauled up, and studding-sails set on both sides, her topsails occasionally collapsing and flapping to the masts for lack of wind to keep them “asleep.” Miss Trevor was, as usual, on deck, seated in a deck-chair, with a book on her lap and the fingers of one hand playing abstractedly with an ear of the great dog that lay stretched contentedly upon the deck beside her. Leslie, also with a book in his hands, was seated right aft upon the taffrail, with his feet upon the stern grating, in such a position that he could look past the helmsman right forward and command the entire starboard side of the deck, as far forward as the windlass-bitts—and, incidentally, study the varying expressions that flitted athwart Miss Trevor’s face as she read. The carpenter, with the rest of the men, was on the forecastle, looking after them and busying himself upon some small job that needed attention. The stillness of the peaceful afternoon seemed to have fallen upon the vessel; the men conversed together intermittently in subdued tones, that barely reached aft in the form of a low mumble; and the only sounds heard were the occasional soft rustle and flap of the canvas aloft, with an accompanying patter of reef-points, the jar of the rudder upon its pintles, the jerk of the wheel chains, and the soft, scarcely audible seething of the water alongside.

Upon this reposeful quietude there suddenly broke the sound of a gentle “wash” of water close alongside, then a long-drawn, sigh-like respiration, and a jet of mingled vapour and water shot above the port bulwark to a height of some ten or twelve feet, so close to the brig that the next instant a small shower of spray came splashing down on the deck in the wake of the main rigging.

So totally unexpected was the occurrence that it startled everybody. Leslie sprang to his feet and looked with mild surprise down into the water; Miss Trevor dropped her book as she shot out of her chair; the dog, who had manifested a readiness to respond to the name of Sailor, leaped up and rushed to the bulwarks, where he reared himself upon his hind legs, emitting a succession of deep, alert barks; and the crew forward shambled over to the port bulwarks, staring curiously.

“Come up here, Miss Trevor,” said Leslie, extending his hand to help the girl up on to the grating beside him. “Here is a sight that you may never have an opportunity to behold again—at least, under such perfect conditions as these.”

The girl, closely attended by Sailor, sprang lightly upon the grating, and following with her eyes Leslie’s pointing finger, gazed down into the blue, transparent depths, where she beheld the enormous black bulk of a large sperm whale, lying right up alongside the brig—so close to her, indeed, that his starboard fin was right under her bilge, about a third of his length—from his blow-holes aft toward his tail—showing shiny as polished ebony, some six inches above water, while his ponderous tail stretched away some forty feet or more beyond the taffrail, where it could be clearly seen gently rising and falling to enable him to keep pace with the brig.

“What a veritable monster!” exclaimed Miss Trevor, gazing down with wide-open eyes of mingled astonishment and dismay at the huge creature, as she clung unconsciously to Leslie’s supporting arm. “Is it dangerous? I hope not, because it looks big enough and strong enough to destroy this ship at a single blow if it chose to do so!”

“You need not be in the least alarmed,” answered Leslie, reassuringly. “He will not hurt us if we do not interfere with him. These creatures are only dangerous if attacked; then, indeed, they have been known to turn upon their assailants, with dire results. But ah! look there!—there is another one!”

And sure enough, up came another of the monsters, breaking water with a rush that showed nearly half his length, at a distance of only some fifty yards from the brig.

“And there is another!” cried Miss Trevor, with unmistakable trepidation, as a third came to the surface and blew close under the brig’s counter.

“Pity as we ain’t a whaler, sir,” remarked the helmsman. “If we was, here ’d be a chance to get fast to two of ’em at once, without so much as havin’ to lower a boat!”
