The sheriff turned and made another elaborate apology for having had to trouble the lady.

I heard Madge tell him that he hadn't troubled her at all, and then, as the cowboys and Camp walked off, she added, "And, Mr. Gunton, I want to thank you for reproving Mr. Camp's dreadful swearing."

"Thank yer, miss," said the sheriff. "We fellers are a little rough at times, but —— me if we don't know what's due to a lady."

"Papa," said Madge, as soon as he was out of hearing, "the sheriff is the most beautiful swearer I ever heard."

For a while there was silence round the station; I suppose the party in 218 were comparing notes, while the two cowboys and I had the best reasons for being quiet. Presently, however, the men came out of the car and jumped down on the platform. Madge evidently followed them to the door, for she called, "Please let me know the moment something happens or you learn anything."

"Better go to bed, Madgy," Albert called. "You'll only worry, and it's after three."

"I couldn't sleep if I tried," she answered.

Their footsteps died away in a moment, and I heard her close the door of 218. In a few moments she opened it again, and, stepping down to the station platform, began to pace up and down it. If I had only dared, I could have put my finger through the crack of the planks and touched her foot as she walked over my head, but I was afraid it might startle her into a shriek, and there was no explaining to her what it meant without telling the cowboys how close they were to their quarry.

Madge hadn't walked from one end of the platform to the other more than three or four times, when I heard some one coming. She evidently heard it also, for she said—

"I began to be afraid you hadn't understood me."
