A narrow strip of clean white sand bordered the whole island, and outside of this again extended the placid waters of the lagoon, barely ruffled by the evening breeze. This lagoon was, as my readers will probably know, the belt of water which surrounded the island, intervening between it and the encircling coral-reef on which the heavy swell expended all its force, without being able to reach and disturb the still water inside.

We were within a mile and a half of the southern extremity of the island, when I detected a thin line of unbroken water tortuously threading its way across the reef, and extending clear into the lagoon. Its mouth would never have been observed from our deck, or indeed from the deck of a ship, for the channel entered the reef at an acute angle; and the surf broke so heavily upon the outside and overlapping ledge that the foam and spray were carried quite across the narrow opening, and mingled with the broken water on the opposite side.

But from my elevation I could see that there the channel was, and having satisfied myself, as we drew down towards it, that it was unbroken, I decided to run in through it.

Had the Lily been a moderately large vessel or square-rigged, she could not have been taken through, for there was one point about midway across the reef where I believed the passage could not exceed thirty feet in width, and it was at a very awkward bend; and there were so many sharp turnings (to use a shore phrase) that a square-rigged vessel’s yards could not have been handled rapidly enough to meet her frequent and quickly succeeding changes of direction. But it was very different with us.

I directed Bob to haul aft his weather-jib-sheet and lee-fore-sheet, thus providing for the keeping of one of the head-sails always full, and to trim his mainsail with a moderately flowing sheet; after which he might leave the canvas to take care of itself, whilst he gave his undivided attention to the helm.

This was soon done, and we bore away in the direction I indicated. The look-out ahead from the deck must have been alarming enough, for great as was Bob’s confidence in my judgment, and steady as were his nerves, he could not forbear hailing me.

“I hope, Harry,” shouted he, “that you’re quite sartain about that there passage. I sees nothing ahead, or anywheres else for that matter, on either bow but surf; and mind ye, lad, if we but touches once, the little barkie ’ll be knocked into match-wood. We may still claw off if there’s any doubt.”

“Port, hard!” answered I, “too intent on the channel to enter into any explanation just then. Steady!”

“Steady!” responded Bob. You stay close to me, dearie, so’s to be within reach if anything happens, and mind you don’t get knocked overboard with the boom. Ah! all right; I sees the opening.

The Water Lily shot in past the overlapping ledge; and my companions on deck were treated to a copious shower-bath of spray for a few seconds, and then we began to feel the shelter of the reef.
