Vernon hesitated. Had Winter stopped a few yards off, he would have begun some banter and drawn him away from the pool. Bob was a woodsman and his eyes were keen. The sun was, however, rising behind the pines and a beam of light touched the sand. There was no use in trying to hide the marks. In fact, Vernon imagined Bob had seen them.

"No," he said. "I thought I'd try to trail the wolf Miss Hyslop talked about."

"Looks as if you'd found some tracks," Winter remarked. "Well, they're not a wolf's." He sat down opposite Vernon. "A man's! I saw another at a soft spot. He followed the girls from the lake and stopped for some time. I allow I reckoned on something like that."

Vernon made an experiment. "Might have been a packer going to a logging camp, or perhaps an Indian."

"Shucks!" said Winter, although he gave Vernon a sympathetic smile. "There are no Indians about the lake and packers' boots don't make marks like those. A city boot and a city man! A fellow who's wise to the bush lifts his feet. Anyhow, I reckon he doesn't belong to your crowd."

"A sure thing!" Vernon agreed. "I can fix where all the boys were. Besides, if somebody in our lot had wanted to talk to Miss Hyslop, he wouldn't have hung around in the woods. My mother's pretty fastidious about her guests. Well, I'll own up the thing bothers me."

Winter nodded. Harry was frank and honest, and Bob imagined he had felt Barbara Hyslop's charm. He was sorry for Harry. The thing was awkward.

"What are you going to do about it?" he asked.

"To begin with, I'm going to hide these tracks. After all, I don't see much light. I suppose I ought to tell my mother and put Mrs. Cartwright wise; but I won't. Spying on a girl and telling is mean. All the same, I'm surely bothered. In a sense, my mother's accountable for her guests and the girl's nice. I'd like it if I could talk to the man."

"Nothing doing there; he'll watch out. Well, we'll hide up his tracks and look for my knife. D'you think Grace Hyslop knew the job was put up?"
