"Say, Harry," said Frank earnestly, as the boys, having bade their leave of Captain Hazzard, who remained on board owing to press of business on the ship, made their way along the maze of wharves and toward a street car.

"Say it," responded Harry cheerfully, his spirits at the tip-top of excitement at the idea of an almost immediate start for the polar regions.

"Well, it's about that Jap."

"Oh that yellow-faced bit of soft-footed putty—well, what about him?"

"Well, that 'yellow-faced bit of putty,' as you call him, is not so easily dismissed from my mind as all that. I'm pretty sure that he had some stronger reason than the one he gave for coming up behind us as silently as a cat while we were talking."

"But Captain Hazzard says that he has had him for years. That he can trust him implicitly," protested Harry.

"Just the same I can't get it out of my mind that there is something wrong about the fellow. I wish he hadn't seen that map and the proposed route of our expedition."

"Oh bosh, you are thinking of what Captain Hazzard said about the Jap secret service. Our friend Oyama is much too thick to be a secret service man."

"He simply looks unimpressive," rejoined Frank. "For that reason alone he would make a good man for any such purpose."

"Well, here comes a car," interrupted Harry, "so let's board it and forget our Japanese friend. Depend upon it you'll find out that he is all O. K. long before we sight an iceberg."
