"Hullo!" hailed back Tom, who, with his two companions, stood at the rail amidships watching the city they were leaving.

"Won't you tell me anything about this trip?"

"That's just it," hurled back Tom at the top of his voice, "we don't know ourselves!"

"Well, I'll be jiggered!" exclaimed Tom Jessop as he turned away from the dock and the moving vessel, which he now felt certain held a mystery within her gray steel sides.


[CHAPTER II.]

NORTHWARD HO!

It was hardly surprising that the ship-news reporter had instantly recognized the Bungalow Boys when he heard their names. Their exploits in many quarters had received numerous columns of newspaper space, much to their amusement. The clever manner in which they had broken up forever the operations of the gang of counterfeiters in the Sawmill Valley, as related in the first volume of this series, "The Bungalow Boys," had brought them before the public. Further interesting "copy" had been made by their wonderful adventures in search of a sunken treasure galleon. Readers of this series were given full details of that adventurous voyage on the surface and below the ocean, in the second volume dealing with our young friends' experiences, which was called "The Bungalow Boys Marooned in the Tropics."

In the third volume we followed them throughout their venturesome doings in the northwest. "The Bungalow Boys in the Great Northwest" showed how pluck and self-reliance can win out even against such a combination as the boys found in the "Chinese runners." The fourth volume dealt with their voyage on the Great Lakes. The mysteries of Castle Rock Island, the ways of the wreckers who captured the lads, and the daring manner in which the boys escaped from the ruined lighthouse, all were set forth in the book in question, which bore the title, "The Bungalow Boys on the Great Lakes."
