Even Jack Cockrell, hopeful to the last, was compelled to agree with the crew of the brig that not a solitary man could be seen on these sea-girt cays and it seemed useless to send off a boat to explore them one by one. There would have been some stir or signal, even if men were too weak to stand. The air was clear and from the brig's masts it was possible to sweep every foot of sandy surface. Here was another mystery of the sea. It occurred to Stede Bonnet to ask:

"You took it for granted they were marooned, Jack, when the boats passed from your sight and you were hidden in the tree in the swamp. What if a quicker death were dealt 'em?"

"That may be, sir."

The brig was leaving the coast astern. Jack moped by himself until his curiosity was drawn to a group of seamen upon the forecastle head who were talking loudly and pointing at something in the water, well ahead of the ship. One vowed it was a big sea-turtle asleep, another was willing to wager his silver-mounted pistols that it was a rum barrel, while a third announced that he'd stake his head on its being a mermaid or her husband. The after-deck brought a spy-glass to bear and perceived that the thing was splashing about. The tiller was shifted to bring it close aboard and soon Captain Bonnet exclaimed that it was, indeed, a merman a-cruising with a cask!

Jack Cockrell scampered to the heel of the bowsprit to investigate this ocean prodigy. And as the cask drifted nearer he saw that Joe Hawkridge was clinging to it. There was no mistaking that dauntless grin and the mop of carroty hair. A handy seaman tossed a bight of line over his shoulders as he bobbed past the forefoot of the brig and he was yanked bodily over the bulwark like a strange species of fish. Flopping on deck he waved a skinny arm in greeting and then Jack Cockrell rushed at him, lifted him bodily, and dragged him to the cabin.

"What ho, comrade!" said the dripping merman. "Blast my eyes, but I was sick with worry for you. I left you in that swamp——"

"And I thought you dead, Joe. For the love o' heaven, tell me how you fared and what——"

Captain Bonnet interfered to say:

"I treated you more courteously than this, Jack. Let us make him comfortable."

Accepting the rebuke, Jack bustled his amazing friend into a change of clothes and saw that he was well fed. Little the worse for his watery pilgrimage, Joe Hawkridge explained at his leisure:
