“Have you succeeded, Harry?” asked Rose, by this time wide awake, and wondering like the others.

“It must have happened in this wise. The wreck was abandoned by us some little distance out here, to windward. The schooner's masts, of course, pointed to leeward, and when she drifted in here, they have first touched on a shelving rock, and as they have been shoved up, little by little, they have acted as levers to right the hull, until the cargo has shifted back into its proper berth, which has suddenly set the vessel up again.”

“Ay, ay, sir,” answered Jack, “all that might have happened had she been above water, or any part of her above water; but you'll remember, maty, that soon after we left her she went down.”

“Not entirely. The wreck settled in the water no faster after we had left it, than it had done before. It continued to sink, inch by inch, as the air escaped, and no faster after it had gone entirely out of sight than before; not as fast, indeed, as the water became denser the lower it got. The great argument against my theory, is the fact, that after the hull got beneath the surface, the wind could not act on it. This is true in one sense, however, and not in another. The waves, or the pressure of the water produced by the wind, might act on the hull for some time after we ceased to see it. But the currents have set the craft in here, and the hull floating always, very little force would cant the craft. If the rock were shelving and slippery, I see no great difficulty in the way; and the barrels may have been so lodged, that a trifle would set them rolling back again, each one helping to produce a change that would move another. As for the ballast, that, I am certain, could not shift, for it was stowed with great care. As the vessel righted, the air still in her moved, and as soon as the water permitted, it escaped by the hatches, when the craft went down, as a matter of course. This air may have aided in bringing the hull upright by its movements in the water.”

This was the only explanation to which the ingenuity of Mulford could help him, under the circumstances, and it may have been the right one, or not. There lay the schooner, however, in some five or six fathoms of water, with her two topmasts, and lower mast-heads out of the element, as upright as if docked! It may all have occurred as the mate fancied, or the unusual incident may have been owing to some of the many mysterious causes which baffle inquiry, when the agents are necessarily hidden from examination.

“Spike intends to come and look for this wreck, you tell me, Jack; in the hope of getting at the doubloons it contains?” said Mulford; when the boat had lain a minute or two longer, riding by the mast-head.

“Ay, ay, sir; that's his notion, sir, and he'll be in a great stew, as soon as he turns out, which must be about this time, and finds me missing; for I was to pilot him to the spot.”

“He'll want no pilot now. It will be scarcely possible to pass anywhere near this and not see these spars. But this discovery almost induces me to change my own plans. What say you, Rose? We have now reached the northern side of the reef, when it is time to haul close by the wind, if we wish to beat up to Key West. There is a moral certainty, however, that the sloop-of-war is somewhere in the neighbourhood of the Dry Tortugas, which are much the most easily reached, being to leeward. We might run down to the light-house by mid-day, while it is doubtful if we could reach the town until to-morrow morning. I should like exceedingly to have five minutes conversation with the commander of the Poughkeepsie.”

“Ay, to let him know where he will be likely to fall in with the Molly Swash and her traitor master, Stephen Spike,” cried Jack Tier. “Never mind, maty; let 'em come on; both the Molly and her master have got long legs and clean heels. Stephen Spike will show 'em how to thread the channels of a reef.”

“It is amazing to me, Jack, that you should stand by your old captain in feeling, while you are helping to thwart him, all you can, in his warmest wishes.”
