"He naded a bath, too, so he did," declared Jimmy. "An, mark my word, he'd be willing to kape it up all the blissed day at the same price, so he would. Now we're safe out from the rocks along the shore, why not hit her up, an' overhaul the rist av the bunch, Jack?"

"Right you are, and here goes," sang out the other. "Take the wheel, Jimmy, and look out for anything in the way. I want to watch how the engine works. You know, George wasn't the only one who overhauled his motor after our fun this last summer."

"She is makin' better toime than she iver did in her whole blissed life!" cried the delighted Jimmy, presently, after Jack had been working at the engine a spell. "Be the powers! I do belave we kin give George a race for his money nixt toime he challenges us, so I do. Hurroo! we're flyin' over the wather, Jack!"

"Less talk, and keep your eyes in front of you!" called the other. "If you get as careless as that tugboat man, we'll be smashing into something, too. And then good-bye to all our hopes for a jolly voyage down the coast."

"Aw! 'tis me that is boring the wather with me eyes all the toime, Jack dear; and never a thing as could escape me aigle vision. I'm a broth of bhoy when it comes to steering a boat, do ye mind."

The stream was wide, and there were far less vessels moving up or down than had been the case above, so that, just as Jimmy declared, it was an easy job to keep clear of obstructions.

Jack had become intensely interested in the splendid working of his reconstructed motor. He was watching its pulsations, and experimenting in many little ways, in order to find out just how to get the maximum of speed from it.

And then, all at once, he heard Jimmy give utterance to an exclamation that might be freighted with either curiosity or alarm—perhaps both.

Hardly knowing what to expect, the skipper of the little Tramp struggled to his knees, and then drew himself erect, to make a discovery that thrilled him through and through.
