"Tonight, you mean," corrected Cameron.

"I started early this morning," replied Ed, "but I guess I've been wandering around the country a good deal. It seems that I came up to the cottage from the north."

Cameron sank back into his chair with a look of satisfaction on his face. The boys now busied themselves getting a substantial meal for Ed, and the boy was soon attacking a generous slice of bear steak.

If Cameron had the plans bearing the thumb marks, he was certainly the man to keep them concealed if he believed them to be of any value whatever to any one. If he did not have charge of the plans, then the chances were that Vin. Chase, the crooked clerk, had them and that any reference to them in the presence of Cameron would be communicated as soon as possible to the actual holder.

Will was certain that Cameron was the man who had given the name of Len Garman by Mr. Horton in the interview in which he had received his instructions. At that time he did not believe that Cameron, or Garman, whichever his name was, knew anything whatever of the thumb prints on the plans.

He did believe, however, that the fellow would fight to the death for the drawings, not because he believed them to be of value as evidence, but because he believed them to be of great value to one in quest of mining machinery suitable for that section of the country.

Directly Cameron began pacing to and fro in the cabin and occasionally glancing out of the window. There were only a few stars in sight and no moon, but for all that the fellow appeared greatly interested in the landscape outside.

"Are you expecting some one?" Will finally asked.

"Certainly not," was the reply. "Why do you ask such a question?"

"Because you seem anxious about something."
