"Black Sam" Hurley was impatiently awaiting the explosion which should tear a gap in the Kenilworth's side and allow his greedy wreckers to begin operations. Ten, fifteen, twenty minutes passed, and there was a great hubbub on board the Bahama schooners tossing at a safe distance from the steamer. At the end of half an hour "Black Sam" ordered a boat away and the crew crowded in pell-mell. They boarded the lee side of the Kenilworth with the agility of monkeys and their bare feet slapped the deck as they ran to the hatch.

Dan heard them and realized that he must try to find a resting-place where they would not discover him upon their return from below. He might perhaps be unseen if he took refuge on the bridge which the wreckers were not likely to ransack until later. He managed to drag his aching, weary body forward and laid down on the mattress behind the canvas weather screen. After a few minutes he heard the wreckers come boiling out of the hold with cries of amazement, anger, and fear. They had expected to find a faulty fuse, but fuse, powder, and all had vanished. Some of them swore the ship was haunted and refused to have anything to do with fetching another sack of powder. Their leader bellowed and threatened, but he could not quell the riot. At last he yelled that he would lay the second charge himself and stay aboard if he blew up with it. Scoffing at the idea of ghostly interference, he ordered his men to search the ship.

These plans were suddenly knocked all askew. Shouting arose on board the schooners whose crews were waving their arms toward the north. The wreckers on the steamer rushed to the side and discovered the cause of alarm. The funnel and upper works of a tug were lifting from the sea, beneath a trailing banner of smoke. Dan had been watching the scene on deck with absorbed attention, and as he looked seaward and caught sight of the tug his heart stood still. He squinted through the glasses. There were two white bands around the funnel. Could it be the Three Sisters of Jacksonville, the big wrecking tug of which Captain Jim's cousin was master? The streaked smoke-stack and the stubby derrick-masts—the drab wheel-house—yes, these were things which Dan remembered noticing when the tug was in Key West. And Captain Jim must be in her. She was hurrying to find out what had become of the Kenilworth. "Perhaps they are looking for me," thought Dan. "And I'm still wrecking master if 'Black Sam' doesn't see me first."

The Bahama wreckers were very busy with their own affairs. The sight of the on-coming tug had altered their campaign in a twinkling. "Black Sam" was now determined to keep possession of the wreck at all hazards, acting on the theory that he was the wrecking master by the law of the Reef. He told his men to stay where they were and slid down the side of the steamer to pull off to the schooners and muster reinforcements. A score of stalwart negroes rallied to his summons and tumbled into their boats.

A picturesque and piratical looking force they were as they scrambled over the Kenilworth's bulwarks and scattered along her sea-scarred decks. "Black Sam" showed his teeth in a snarl as he yelled to them:

"Dey ain't gwine be no argifying 'bout dis yere wreck. We'se heah an' we stay heah. If dem tow-boat folks tries to come aboard, keep 'em busy wid dem belaying-pins yondah an' yo' knives—yo' heah me?"

The Three Sisters was rapidly nearing the scene. From his ambush Dan watched her with yearning, happy eyes. He was not yet out of trouble, but Captain Jim would somehow rescue him in the nick of time. He saw the powerful tug sweep around to leeward of the Bahama schooners and slow down as if her people were trying to fathom the situation. Captain Jim Wetherly was standing by the wheel-house door, shading his eyes with his hand. Dan wanted to call to him, but he dared not show himself. The tug crept nearer, and Dan rejoiced to discover that most of the Resolute's crew were clustered along the lower deck, including the portly chief engineer, Bill McKnight, who loomed like a whale among minnows.

Presently Captain Jim sung out:

"What are you Bahama niggers doing aboard that steamer? She belongs to me. I had hold of her once and am in charge of wrecking her. Clear out before I put my men aboard."

A row of black heads bobbed in violent agitation along the Kenilworth's bulwarks, and "Black Sam" Hurley shouted back with a loud laugh:
