"Look at the flap of the tent here!" he exclaimed. "I'm dead sure I fastened it tight behind me; and I was the last one in there. It's hanging loose, right now!"

"Wow, so's ours!" whooped Steve, furiously.

The boys plunged into the tents, anxious once more concerning the state of affairs; and immediately a chorus of indignant outcries told that they found things otherwise than satisfactory.

"Somebody's been rooting around in here!" called out Steve, from the depths of the second tent.

"And mauled all our duds, too! Look at the stuff scattered around, would you?" Bandy-legs was heard to howl.

"Looks like the thief wanted to find something or other, and must have been frightened off by hearing us coming," Owen declared, also a bit angrily.

As yet there had come no loud outcries from the other tent; but that was not because those who had rushed inside found things just to their satisfaction. Max was always a fellow of few words; and as for Toby, he never could express himself intelligently when tremendously excited. He just stood there, with his lower jaw moving up and down, yet no sound following the action.

There was good reason for this feeling of dismay on the part of the pair occupying the smaller tent, where most of the provisions were kept. For they had discovered, as soon as they entered, that everything was thrown about, helter-skelter. Indeed, it looked as though the unknown thief must have been gathering together pretty much all their supplies in the shape of foodstuff, with the evident intention of carrying the same off; when, alarmed by their coming, he had grabbed up a strip of breakfast bacon, the last loaf of bread, and possibly a can of baked beans, with which he had hastily decamped.

Max, after the first flush of his indignation had passed away, was rather amused than otherwise by the affair. The loss had not been so very great after all, since no damage had been done to the precious canoes. And if it came to the worst, one of the campers could easily be dispatched to the home town to buy more provisions, since they had plenty of money still in the treasury, thanks to those wonderful little pearls, taken from the waters of this same Big Sunflower River.

As usual with him, Max began to cast around in order to find some clew to the identity of the thief. Of course the other three had by this time hurried into the smaller tent to ascertain what the extent of the damages might be. And loud were the wailings of Bandy-legs when he heard that among the missing things was the splendid strip of bacon, on which he had cast many an envious eye, as he contemplated future enjoyment, with slices of the same sizzling in a hot frying pan, and sending off the odors that made him positively ravenous with hunger.
