If there was any doubt in their minds it was dispelled by a faint halloo from the swimmer, accompanied by a warning cry for them to make no noise.

“That’s queer,” said Harvey. “Something’s up when Tim doesn’t want a noise. I wonder if anything has gone wrong.”

Little Tim, climbing aboard a few moments later, and telling his story in excited tones, quickly apprised them that things were decidedly wrong up the Thoroughfare. Wrong indeed! The yachtsmen were thunderstruck.

Jack Harvey brought the Viking into the wind as near shore as he dared.

“Bully for you, Tim!” he exclaimed. “Now take the dory and get ashore quick, and bring the rest of the crew down here.”

Tim was away for shore in a twinkling. A few minutes later the four could be seen coming down on the run. They piled aboard the Viking in a heap, and the yacht stood along up the Thoroughfare once more.

“Well, what are we going to do, Jack?” inquired Henry Burns, as they turned a bend of the shore and came in sight of the mast of the Seagull.

“I’m going to fight for that boat!” cried Harvey, angrily. “I’ll die for it, but they sha’n’t get it away from me.”

“Of course we’ll fight for it if we need to,” said Henry Burns, calmly. “We will all stand by you, eh, fellows?”

“Yes, sir,” exclaimed Tom and Bob together, feeling of their muscles, developed by canoeing and gymnastics.
