Waves from the exhausted swimmers sent bright streaks of watershine wavering up the green hull over Madden's head. Utter silence pervaded the vessel. There was no creaking of spar or block. Hot tar stood in her seams in the beating sunshine.

The boys kicked wearily through the tepid water to the schooner's prow, where Greer succeeded in catching the bobstays and climbing aboard. A little later he lowered a rope to Madden with a double bight in it. The Yankee made the Englishman fast in the loops, climbed on deck himself and helped haul the unconscious fellow aboard.

The two boys lugged the senseless man wearily across deck into the shade of the superstructure, then in default of any better restorative, Leonard began slapping the bottom of the Englishman's feet to revive him. Presently Caradoc groaned, drew up his legs.

"He's coming around all right," said Greer, then he looked about him. "What do you make out of this anyway, Mr. Madden?"

Leonard glanced around and did see a remarkable derelict. The schooner was as newly painted and trig as if fresh from the ways. Her deck was holystoned to man-o'-war cleanliness; every sheet, hawser, stay, tackle, pin, spike, was in place. Three small boats, her full complement, hung in davits. On the bow of these boats, on their oars and buoys, was painted the name of the schooner, "Minnie B."

From the port side of the vessel there stretched a long cable patently leading to a sea anchor. All sails were brailed except mains'l and tops'l, which were reefed and set against each other to hold her steady in case of a blow. The funnel was freshly painted black with a red band at the top. Judging from her appearance, the desertion of the Minnie B had been carefully planned. Yet why desert a new vessel? By what means did the crew leave the schooner, since all her small boats remained?

What was their motive in anchoring the Minnie B in the middle of the Sargasso?

There appeared to be no easy answer to these questions.

"I don't understand this," said Greer, in answer to Madden's unspoken perplexity. "Where did the crew go, sir, and how did they go?"

"They might have deserted her for her insurance," suggested Madden tentatively.
