One night, during the middle watch, the captain came on deck, and took to walking up and down with the second mate. The night was clear, though dark. The Chrysolite was close-hauled on the starboard tack, and was making good headway under a clinking breeze. She was an old-fashioned, frigate-built, full-rigged ship, such as one seldom happens on now, her quarter-galleries, chain-plates, to' gallant bulwarks, and single topsail-yards being all out of date among the ship-builders of to-day. It has been said that she had "rare lines," and the remark was just. A more imposing pile of timber was possibly never floated. She had plenty of beam to cope with the South Atlantic wave-giants, and not too much sheer. Her fiddle-stem was gracefully cut, and harmonised to perfection with the slight rake aft of her lofty masts. Her spars, also, were finely proportioned to the breadth of her hull. So that, with her canvas spread in an unwavering breeze, the Chrysolite was a stately creature and "a thing of beauty." "Mr. Grant," said the captain, addressing his subordinate officer, "be good enough to take a star and work out the ship's position." The second mate quickly brought his sextant, and took the altitude of a star convenient for his purpose. He then went below to the cabin to perform his calculations. The lookout man, a ready sleeper, was in a heavy slumber, upon which the stiffening breeze made no effect. The rest of the watch had disappeared in the customary fashion. Captain Anderson was practically alone on deck. He walked forward, leaned over the weather-rail, and directed his glass. He saw just exactly what he expected to see. There, right ahead in the distance, the binoculars showed a long, thin streak of sparkling silver, appearing like a lightning flash held fast between the darkness and the deep sea. It was phosphorescent water playing on a sand-bank. Anderson put the glass into his pocket. He was sullen and determined. He stood motionless for full half an hour, trying to repress the workings of an aroused conscience; but his thoughts would not let him alone. There was something behind them, some new sensations, which set them buzzing in his mind. These sensations were his finest feelings--ennobling emotions which had been cramped in the grip of discipline for forty years. He could not comprehend it, but he found himself pursuing a train of thoughts of finer sensibility than he had ever experienced, and in which the great bribe had no place. He foreshadowed in his mind's eye the tragic events over which he was now presiding. He foresaw the danger to life and limb with a fresh clearness of vision. He pictured to himself the possible agonies of his fellow-creatures (never once thinking of his own) with a sentiment much akin to pity--strong, too, but not sufficiently strong to overcome that unbending guide which forbade him for honour's sake to go back upon his promise. Then there was the doom of the ship itself--
