"I guess we'd all like to do that," responded Shadow. "Nevertheless, if he is the real Dave Porter you can't blame him for trying to prove it."

"There is only one thing about it that troubles me," said Luke. "Don't you remember that all of those who saw this Ward Porton agreed that he looked very much like Mr. Dunston Porter?"

"Yes, but Dave looks like Dunston Porter, too," came quickly from Ben.

"It's queer that he resembles his uncle more than he does his father," was Shadow's comment. "Maybe this Ward Porton resembles Mr. David Porter."

"Well, it's fierce; that's all I've got to say," declared Ben. "And what Dave is going to do if they prove he isn't the real Dave Porter is something I don't like to think about. In those days when we first went to Oak Hall, you'll remember how bitter he felt when some of his enemies referred to him as that 'poorhouse nobody,' and how eager he was to clear up the mystery of his identity, even though it cost him a trip to the South Sea Islands."

Dave walked on and on along the lake shore, paying little attention to where he was going. His mind was in a state bordering on bewilderment. In a faint, uncertain way he had anticipated some such calamity, but now that the blow had fallen, the matter looked almost hopeless to him. Had he followed his own inclinations, he would have made preparations to return to Crumville at once.

"But evidently they don't want me there," he told himself, bitterly. "They want to solve this mystery without my interference. And if they do make up their minds that I am not the real Dave Porter, I wonder how they will treat me? Of course, they may be very kind to me—the same as Laura and Jessie and the others up here. But kindness of that sort isn't everything. I don't want any one to support me if I haven't some claim on him." And then Dave shut his teeth hard, clenched his hands, and walked on faster than ever.

Finally tired out because he had been on his feet since early morning, Dave sat down on a flat rock to rest. As he did this, he heard the put-put of a motor, and presently around a bend of the shore showed the headlight of Mr. Appleby's motor-boat.

"I wonder if they are simply going down to the end of the lake, or whether they are going to stop at our place," said Dave, to himself. "I'd rather they wouldn't stop at Bear Camp to-night, when everything is so upset."

As the motor-boat swung around, the headlight flashed full upon our hero and there followed an exclamation from the manager of the moving-picture company, who was at the wheel of the craft, with two men beside him.
