"There was no use for her to run in and take the risk, without good luck having turned up on the island; yet any sign she could profit by must be both sufficient to reach sixty miles or so, and hidden enough not to alarm the telegraphs or the cruisers. Here was a worse puzzle than all, and I only guessed at it for my own satisfaction--as a fellow can't help doing when he hears a question he can't answer--till my eye lighted on Diana's Peak, near three thousand feet above the sea. There it was, by Jove! 'Twas quite clear at the time; but by nightfall there was always more or less cloud near the top; and if you set a fire on the very peak, 'twould only be seen leagues off: a notion that brought to mind a similar thing which I told you saved the Indiaman from a lee-shore one night on the African coast--and again, by George! I saw _that_ must have been meant at first by the negroes as a smoke to help the French brig easier in! Putting that and that together, why it struck me at once what the fourth black's errand might be--namely, to watch for the schooner, and kindle his signal as soon as he couldn't see the island for mist, I was sure of it; and as for a dark night coming on at sea, the freshening of the breeze there promised nothing more likely; a bright white haze was softening out the horizon already, and here and there the egg of a cloud could be seen to break off the sky to windward, all of which would be better known afloat than here. "The truth was, I was on the point of tripping my anchor to hurry down and get aboard again, but, on standing up, the head of a peak fell below the sail I had noticed in the distance, and, seeing she loomed large on the stretch of water, I pretty soon found she must be a ship of the line. The telegraph over the Alarm House was hard at work again, so I e'en took down my glass and cleaned it to have a better view, during which I caught sight, for a minute, of some soldier-officer or other on horseback, with a mounted red-coat behind him, riding hastily up the gully a good bit from my back, till they were round the red piece of crag, turning at times as if to watch the vessel. Though I couldn't have a better spy at him for want of my glass, I had no doubt he was the Governor himself, for the sentries in the distance took no note of him.
