“Dinner bell at the hotel,” said Nelson.

“Sounded like a riot call,” observed Dan. Then they piled into the tender and went ashore, to be ushered, four very sedate and well-behaved young gentlemen, into the dining room.

It was all of an hour later when Tom was finally separated from the table and led protestingly back to the porch.

“But I wanted some more frozen pudding!” he explained.

“Of course you did,” answered Bob soothingly. “But you must remember that we’re only paying for one dinner apiece, Tommy. Don’t bankrupt the hotel right at the beginning of the season.”

“Hope you ch-choke!” said Tom.

Later they rowed back to the launch over the peaceful cove, which was shot with all sorts of steel-blue and purple lights and shadows. Across the cove Rocky Neck was a blurred promontory of darkness, with here and there a yellow gleam lighting some window and finding reflection in the water below. Seaward, the harbor was still alight with the afterglow, and the lantern at the end of the breakwater showed coldly white in the gathering darkness. It had grown chilly since sunset, and so, after making all fast for the night, the boys went below and closed the doors and hatch behind them. With the lamps going, the cabin soon warmed up. Bob, by request, had brought his mandolin, and now, also by request, he produced it and they had what Nelson called a “sing-song,” Tom alternately attempting bass and soprano, and not meeting with much success at either. Finally Bob tossed the mandolin onto the bunk and said he was going to bed. That apparently casual remark seemed to remind Dan of something, for he suddenly sat up on the edge of the berth and grabbed Tom by the arm.

“We haven’t given them our stunt yet, Tommy,” he said.

“Eh? What stunt? Oh, yes; that’s so! Come on!” And Tom climbed to his feet. Dan joined him, and they stood very stiffly at attention.

“What’s this?” asked Bob.
