As for the scheme I had in my head, it was not a bad one in itself. I was to go down the sandy spit that divides the anchorage on the east from the open sea, find the white rock I had observed last evening, and ascertain whether it was there or not that Ben Gunn had hidden his boat, a thing quite worth doing, as I still believe. But as I was certain I should not be allowed to leave the enclosure, my only plan was to take French leave and slip out when nobody was watching, and that was so bad a way of doing it as made the thing itself wrong. But I was only a boy, and I had made my mind up. Well, as things at last fell out, I found an admirable opportunity. The squire and Gray were busy helping the captain with his bandages, the coast was clear, I made a bolt for it over the stockade and into the thickest of the trees, and before my absence was observed I was out of cry of my companions. This was my second folly, far worse than the first, as I left but two sound men to guard the house; but like the first, it was a help towards saving all of us. I took my way straight for the east coast of the island, for I was determined to go down the sea side of the spit to avoid all chance of observation from the anchorage. It was already late in the afternoon, although still warm and sunny. As I continued to thread the tall woods, I could hear from far before me not only the continuous thunder of the surf, but a certain tossing of foliage and grinding of boughs which showed me the sea breeze had set in higher than usual. Soon cool draughts of air began to reach me, and a few steps farther I came forth into the open borders of the grove, and saw the sea lying blue and sunny to the horizon and the surf tumbling and tossing its foam along the beach. I have never seen the sea quiet round Treasure Island. The sun might blaze overhead, the air be without a breath, the surface smooth and blue, but still these great rollers would be running along all the external coast, thundering and thundering by day and night; and I scarce believe there is one spot in the island where a man would be out of earshot of their noise. I walked along beside the surf with great enjoyment, till, thinking I was now got far enough to the south, I took the cover of some thick bushes and crept warily up to the ridge of the spit. Behind me was the sea, in front the anchorage. The sea breeze, as though it had the sooner blown itself out by its unusual violence, was already at an end; it had been succeeded by light, variable airs from the south and south-east, carrying great banks of fog; and the anchorage, under lee of Skeleton Island, lay still and leaden as when first we entered it. The HISPANIOLA, in that unbroken mirror, was exactly portrayed from the truck to the waterline, the Jolly Roger hanging from her peak.
