He must have turned hastily and retreated after the flash. What he thought the sudden dazzling illumination was caused by, the boys had no means of knowing.

Jerry and Bluff were now getting ready to start on their mission in search of supplies. They both expressed the hope that these could all be procured, once they reached the distant village on the lake shore, many miles off.

It promised to be an interesting trip, for they would pass along a shore neither of them had ever examined at close range before. To those who love outdoor life there is always a novelty about exploration. With new and interesting scenes opening up constantly before the eyes the senses are kept on the alert.

Bluff even had the temerity to suggest that Will loan them his camera for the occasion.

"We might run across some dandy pictures that would be worth while snapping off, you know, Will," he went on to say in a wheedling tone of voice, which Bluff knew so well how to use.

Will, however, shook his head. Usually he was of a most accommodating nature; and on numerous occasions had willingly entrusted his highly valued camera into the keeping of the other boys, who knew how to use it almost as well as did the owner himself.

"I'd rather not, if it's all the same to you, Bluff," he remarked slowly.

"Oh! well, just as you say," declared the other, shrugging his broad shoulders as though it did not matter much after all, and as if taking care of the camera might possibly prove a task rather than a pleasure; "I reckon you're thinking about the chances of my dropping it overboard; or our running into a storm where the little old black box might get soaked and ruined."

"Not so much that, Bluff, as that I want to do some work on the camera," explained Will. "There's a little matter that really needs adjusting, and I told myself I'd fix it this morning sure. Then again I've laid out a scheme for to-day that if it works will call for the use of the camera."

"That's all right, Will," remarked the other, briskly; "it doesn't matter a pin to me, only I thought you mightn't ever be going all the way to that village; and something fine could be run across between here and there."
