At last they drew near to the break in that interminable gangway. A spur of coral sand stood forth on the one hand; on the other a high and thick tuft of trees cut off the view; between was the mouth of the huge laver. Twice a day the ocean crowded in that narrow entrance and was heaped between these frail walls; twice a day, with the return of the ebb, the mighty surplusage of water must struggle to escape. The hour in which the Farallone came there was the hour of flood. The sea turned (as with the instinct of the homing pigeon) for the vast receptacle, swept eddying through the gates, was transmuted, as it did so, into a wonder of watery and silken hues, and brimmed into the inland sea beyond. The schooner looked up close-hauled, and was caught and carried away by the influx like a toy. She skimmed; she flew; a momentary shadow touched her decks from the shore-side trees; the bottom of the channel showed up for a moment and was in a moment gone; the next, she floated on the bosom of the lagoon, and below, in the transparent chamber of waters, a myriad of many-coloured fishes were sporting, a myriad pale-flowers of coral diversified the floor. Herrick stood transported. In the gratified lust of his eye, he forgot the past and the present; forgot that he was menaced by a prison on the one hand and starvation on the other; forgot that he was come to that island, desperately foraging, clutching at expedients. A drove of fishes, painted like the rainbow and billed like parrots, hovered up in the shadow of the schooner, and passed clear of it, and glinted in the submarine sun. They were beautiful, like birds, and their silent passage impressed him like a strain of song. Meanwhile, to the eye of Davis in the cross-trees, the lagoon continued to expand its empty waters, and the long succession of the shore-side trees to be paid out like fishing line off a reel. And still there was no mark of habitation. The schooner, immediately on entering, had been kept away to the nor'ard where the water seemed to be the most deep; and she was now skimming past the tall grove of trees, which stood on that side of the channel and denied further view. Of the whole of the low shores of the island, only this bight remained to be revealed. And suddenly the curtain was raised; they began to open out a haven, snugly elbowed there, and beheld, with an astonishment beyond words, the roofs of men.
