"The trouble—whatever it is—is in that note, too," Betty interrupted, returning him the paper with the deliberate intention of checking his outburst.

Mason gave her a quick glance of approval. Though he did not approve of women in a lumber camp, Betty's quiet capacity, her gentle womanliness, with her great strength of character and keenness of perception underlying it, pleased him immensely. He admired her, and curiously enough frequently found himself discussing affairs of the camp with her as though she were there for the purpose of sharing the burden of his responsibilities. In the ordinary course this would not have happened, but she had come at a moment when his difficulties were many and trying. And at such a time her ready understanding had become decided moral support which was none the less welcome for the fact that he failed to realize it.

"You're right," he nodded. "There's something doing. What's that?"

All three glanced at the door. And there was a look of uneasiness in each which they could not have explained. Mason hurried across the room with Chepstow at his heels.

Outside, night was closing in rapidly. A gray, misty twilight held the mountain world in a gloomy shroud. The vast hills, and the dark woodland belts, loomed hazily through the mist. But the deathly stillness was broken by the rattle of wheels and the beating of hoofs upon the hard trail. The vehicle, whatever it was, had passed the dugout, and the sounds of it were already dying away in the direction of the distant camp.

"There's a fog coming down," observed Mason, as they returned to the stove.

"That was a buckboard," remarked the parson.

"And it was traveling fast and light," added Betty.

And each remark indicated the point of view of the speaker.

Mason thought less of the vehicle than he did of the fog. Any uneasiness he felt was for his work rather than the trouble he felt to be brewing. A heavy fog was always a deterrent, and, at this time of year, fogs were not unfrequent in the hills. Chepstow was bent on the identity of the arrival, while Betty sought the object of it.
