“Well, I can’t understand the matter at all,” said the ranchman. “Lish had some object in sending me that note, but what it was I don’t know. But I do know that the mule is mine, and that I must have him if I have to fight for him.”

INSIDE THE DUG-OUT.

Poor Oscar! This was a most unexpected and disastrous ending to the expedition upon which he had set out with such high hopes.

Thompson,” he added, turning to his guide, who had stood by, an interested listener to all that had passed between the ranchman and his employer, “what will you take for your pony?”

“Wal,” said the latter, suddenly straightening up and winking hard, as if he had just been aroused from a sound sleep, “he aint fur sale, that there hoss aint.”
