"Next moment I was thinking of old Bob Martin's particular landmarks at the river-mouth he spoke of, and the notion of its possibly being hereabouts glanced on me like a godsend. In the unsure dusky sight I had of it, certainly, it wore somewhat of that look, and it lay fair to leeward of the weather; while, as for the dead shut-in appearance of it, old Bob had specially said you'd never think it was a river; but then again it was more like a desperate fancy owing to our hard case, and to run the ship straight for it would be the trick of a Bedlamite. At any rate, a quick cry from aft turned me round, and I saw a blue flare of lightning streak out betwixt the bank of grey haze and the cloud that hung over it--then another, and the clouds were beginning to rise slowly in the midst, leaving a white glare between, as if you could see through it towards what was coming. The men could pull no longer, but ahead of the ship there was now only about eight or ten fathoms water, with a soft bottom. The boats were hoisted in, and the men had begun to clue up and hand the topsails, which were lowered on the caps, when, just in the midst of the hubbub and confusion, as I stood listening to every order the mate gave, the steward came up hastily from below to tell him that the captain had woke up, and, being much better, wanted to see him immediately. Mr Finch looked surprised, but he turned at once, and hurried down the hatchway. "The sight which all of us who weren't busy gazed upon, over the larboard bulwarks, was terrible to see: 'twas half dark, though the sun dropping behind the haze-bank, made it glimmer and redden. The dark heap of clouds had first lengthened out blacker and blacker, and was rising slowly in the sky like a mighty arch, till you saw their white edges below, and a ghastly white space behind, out of which the mist and scud began to fly. Next minute a long sigh came into her jib and foresail, then the black bow of cloud partly sank again, and a blaze of lightning came out all round her, showing you every face on deck, the inside of the round-house aft, with the Indian judge standing in it, his hand to his eyes--and the land far away, to the very swell rolling into it. Then the thunder broke overhead in the gloom, in one fearful sudden crack, that you seemed to hear through every corner of cabins and forecastle below--and the wet back-fins of twenty sharks or so, that had risen out of the inky surface, vanished as suddenly.
