The handwriting was strange to him, and while Tom Chepstow was reading Mason's letter he tore the other open. As he read, the gravity of his face slowly relaxed. At last an exclamation from the parson made him look up.

"This is terrible, Dave!"

"It's a bit fierce," the other agreed. "Have you read it all?" he inquired.

"Yes."

"Then you've got my meaning in coming to you?"

"I see. I hadn't thought of it."

Dave smiled into the other's face.

"You're going to do it for me? It may mean weeks. It may even mean months. You see, it's an epidemic. At the best it might be only a couple of weeks. They're tough, those boys. On the other hand it might mean—anything to me."

Chepstow nodded. He understood well enough what an epidemic of mountain fever in his lumber camps must mean to Dave. He understood the conditions under which he stood with regard to his contract. A catastrophe like that might mean ruin. And ruin for Dave would mean ruin for nearly all connected with Malkern.

"Yes, I'll do it, Dave. Putting all friendship on one side, it is clearly my duty. Certainly. I'll go up there and lend all the aid I possibly can. You must outfit me with drugs and help."
