But the puzzle was too difficult for him, and he finally abandoned it to dismount and practice the things the agent had taught him.

Such action at first mystified Firefly, but Bob patted and spoke to him, explaining what he was trying to do just as though he were talking to a human being.

"You and Chester and I will have many a long day and night together, so we had better be good friends right away. I've got to learn to hobble and saddle and I want to do it before I return to the ranch."

Evidently satisfied with this explanation, Firefly stood quietly, nibbling at the grass now and again, while the dog sat down and watched operations.

Having finally acquired the knack, Bob remounted and was soon at the ranch, where he turned his pony into the corral and carried his saddle to the cabin.

"Then you've learned enough to turn your pony into the corral, eh?" was Ford's greeting as Bob threw his saddle on the floor.

"Yes, sir. And to hobble and saddle and make my horse whirl when I'm mounting."

"Hal's a good friend to have," commented the ranchman. "Did he show you how to throw a rope?"

"Do you mean my lariat?"

"No, I mean rope; that's what we call it on the plains, though it means the same thing."
