“There might be a shadow of reason for their talk in one direction,” he admitted, slowly and reluctantly. “But, pshaw, no; I’m dreaming. No, there can’t be any reason for wanting to ruin my boat. Very likely you didn’t hear quite right.”

“At any rate,” Halstead went on, “Joe and I will be aboard to-night, and probably every night as long as we’re in your employ.”

“You seem to take this thing seriously, Halstead.”

“I don’t believe, sir, in throwing away what seems like a very valuable hint. It won’t do any harm for us to be watchful, anyway. By the way, sir, do you mind letting the dog stay aboard, too?”

“Certainly you may have him,” nodded the owner. “He won’t interfere with you and he’ll sleep with one eye and both ears open. Well, make yourselves at home here, boys. Do whatever you please in the galley and feed and water Bouncer. I’ll be at the hotel this evening in case you should want me for anything.”

After impressing upon Bouncer that he was still to remain aboard, Mr. Dunstan strolled leisurely down the pier. Both boys went hard at work.

“What do you make of our new employer?” asked Joe after a while.

“He seems like an ordinary, easy-going man,” Tom replied. “I don’t believe he ever startled anyone by doing anything very original, but he’s a gentleman, and we’re going to find him considerate and just. That’s all we can ask in any man.”

After that there wasn’t much talk, except the few words now and then that related to taking the motor to pieces, and repairing and replacing its parts. At the close of day they helped themselves to a bountiful meal and made a fast friend of Bouncer by catering to his healthy appetite. Then, by the light of lanterns, they went to work again. It was after eleven o’clock when they found themselves too drowsy to do further justice to their work.

“Let’s go up on deck and get some air. After that we’ll turn in,” proposed Halstead.
