The white rock, visible enough above the brush, was still some eighth of a mile farther down the spit, and it took me a goodish while to get up with it, crawling, often on all-fours, among the scrub. Night had almost come when I laid my hand on its rough sides. Right below it there was an exceedingly small hollow of green turf, hidden by banks and a thick underwood about knee-deep, that grew there very plentifully; and in the center of the dell, sure enough, a little tent of goat-skins, like what the gypsies carry about with them in England. I dropped into the hollow, lifted the side of the tent, and there was Ben Gunn's boat--homemade if ever anything was homemade--a rude, lopsided framework of tough wood, and stretched upon that a covering of goat-skin, with the hair inside. The thing was extremely small, even for me, and I can hardly imagine that it could have floated with a full-sized man. There was one thwart set as low as possible, a kind of stretcher in the bows, and a double paddle for propulsion. I had not then seen a coracle, such as the ancient Britons made, but I have seen one since, and I can give you no fairer idea of Ben Gunn's boat than by saying it was like the first and the worst coracle ever made by man. But the great advantage of the coracle it certainly possessed, for it was exceedingly light and portable. Well, now that I had found the boat, you would have thought I had had enough of truantry for once; but in the meantime I had taken another notion, and become so obstinately fond of it that I would have carried it out, I believe, in the teeth of Captain Smollett himself. This was to slip out under cover of the night, cut the _Hispaniola_ adrift, and let her go ashore where she fancied. I had quite made up my mind that the mutineers, after their repulse of the morning, had nothing nearer their hearts than to up anchor and away to sea; this, I thought, it would be a fine thing to prevent, and now that I had seen how they left their watchman unprovided with a boat, I thought it might be done with little risk. Down I sat to wait for darkness, and made a hearty meal of biscuit. It was a night out of ten thousand for my purpose. The fog had now buried all heaven. As the last rays of daylight dwindled and disappeared, absolute blackness settled down on Treasure Island. And when, at last, I shouldered the coracle, and groped my way stumblingly out of the hollow where I had supped, there were but two points visible on the whole anchorage. One was the great fire on shore, by which the defeated pirates lay carousing in the swamp. The other, a mere blur of light upon the darkness, indicated the position of the anchored ship. She had swung round to the ebb--her bow was now toward me--the only lights on board were in the cabin; and what I saw was merely a reflection on the fog of the strong rays that flowed from the stern window.
