While he spoke he rested a long-barrelled six-shooter of the heaviest pattern in the hollow of his arm, with its muzzle pointing directly at the heart of the giant mate. The man with the pale eyes sat upon the taffrail with his Colt automatic in readiness, and looked Smart and the two men over without a word. Speech was unnecessary. The iconoclast had done all that was needed to bring about a perfect understanding, and, as both men were armed with guns that admitted of some respect, the Sea-Horse held her way over the reef under all sail, while the freshening breeze heeled her gradually over until she fairly tore along through a calm sea, leaving a snowy, boiling wake astern.

Bahama Bill looked his men over. He feared neither gun nor knife when the time came for a fracas, but there was another consideration which moved him deeper than the threat of the thin-faced invalid. The marshal had libelled his vessel upon an occasion, for the payment of a small bill. Here he was forced, at the point of a gun, to run away, to carry the evident prey with him. It would exonerate him if caught, for he could prove that it was a matter he had no discretion in. He could, with all safety, put as much space between the two vessels as possible. All hands would swear that he was forced to do so.

The idea tickled him, and his huge, ugly mouth broadened out into a sinister grin as the Sea-Horse, racing along through the choppy water of the edge of the Gulf Stream, poked her short horn out over the foam, and tore away to windward.

The box in the cabin excited his curiosity, but he felt sure that it was of value, and that the men were trying to make a getaway with it. Smart was sitting quietly watching the affair, and being, like the mate, under the guns of the passengers, there was nothing to do but obey orders, or take the consequences.

"Seems like your health has improved wonderfully since you dined on the ship's grub," said the yacht captain, addressing the invalid, who held the revolver.

"The sea air is good for the health," assented that gentleman, his thin face lining up into something resembling a smile. "It'll be healthy for all of us out here in the broad ocean, free from all cares. Oh, the life on the bounding wave for me—isn't that so, Jim?" said he, referring to his companion.

The sharp "ping" of a bullet interrupted the answer, and it was found that to be perfectly safe it was necessary to remain under cover.

"Those bullets would go through the ship both ways and back again," said the invalid, as the rest snuggled down, "but of course it's well to keep out of sight. Better put everything you can on her, skipper," he added, addressing the mate, "if you want to keep clear. Let her go. Don't stop on our account. When we get an offing, I'll trust you to steer without trouble, and I'll put out a line to catch some supper. There ought to be fine fishing off the reef this time of year."
