“He keeps going toward Purvis,” said Dick, who had once more resorted to his field glass; “he seems to be certain he has misled us.”

“Why shouldn’t he be? His last view showed him we were fishing as hard as ever and he must believe we shall not figure any more in his affairs.”

“Well, Dick, we must be up and doing if we expect to help Bunk.”

“True; we are through fishing for the present.”

They flung the lines down in the boat, Dick took up the paddle.

“If we have to camp out to-night, we shall have our supper with us. There’s some consolation in that. I don’t believe the Professor will show up again before to-morrow morning. He may have his invention completed by that time, but everything must remain guesswork for awhile.”

Under the propulsion of the paddle the light craft skimmed swiftly over the placid lake. Dick put forth all his skill and the canoe touched the shingle a few minutes later and both stepped ashore and drew the boat up the shore.

“It strikes me, Harv, that it will be better for us to separate. We don’t know whether to hunt for Bunk at the place where the Professor halted awhile ago, or to look for him farther over to the right where I have seen his machine several times.”

“I should say that the spot you saw is most likely the right one.”

“So it seems to me, but the afternoon is so far gone that we shall need every minute and we mustn’t go too far astray. It’s a safe guess that one of us will establish communication with Bunk pretty soon.”
