Thad examined the engine carefully. He knew considerable about such things, and yet he fancied, he might have more or less trouble with the motive power of this Lake Superior boat; for it was of rather an ancient pattern, and had evidently seen its best days.

Between them Thad and Allan confessed this much, but they did not think it good policy to say anything to the others, though anxious Bumpus watched their conference uneasily, and could be seen to carefully pick out a spot on the rail where he perched, and seemed inclined to stay—it was handy to a quick getaway in case the worst happened, and the engine blew up, as he whispered to himself.

After he had, as he believed, mastered the rudiments of the working of the motor Thad told them to cast off, and they would make a start. Several men stood around to watch them get away, among them the party in whose charge the boat had been left, and who had only delivered it up after Thad had produced an order for the same, and paid certain expenses for storage and watching.

"Were moving at last!" called Step Hen excitedly, as the machinery started to go with a rush, after Thad had cranked the engine.

Allan stood by the wheel, and as the prow of the boat gurgled through the clear waters of the great lake, every scout was thrilled with the vast possibilities that faced them, now that their cruise had begun.

"This means that we'll eat our first meal aboard at noon to-day," remarked Giraffe who seemed determined that no regular feeding time might be neglected, if he could help it.

"You ought to be a happy fellow, Giraffe," remarked Davy Jones, "after taking a look over the piles of grub we've got aboard. Why, do you know there's a whole big ham, two slabs of bacon, and all sorts of good things. No danger of any of us going hungry on this excursion; unless the old tub should happen to sink, and leave us marooned on some rocky island."

"Oh! see here, stop joking about that sort of thing, Davy," remonstrated Bumpus, shivering as though he felt a cold draught; "I know right well that if such a horrible thing ever did happen to us, the rest of you'd make up your minds to begin on me the first thing."

"Well, that's the penalty you have to pay, Bum, pus, for being so tempting," chuckled Step Hen; "now, who'd ever think of picking Giraffe out for a dainty meal; why he's as skinny as an old crow."

"There are times when it pays right well to be thin," remarked the scout held up to derision, "and that'd be one of 'em, I reckon."
