"Guess you don't know much about that saloobrious portion of the world if you ain't had the pleasure of a Greaser's company. Why, son, he's a varmint that's about one-fourth Mexican, one-fourth Spaniard, one-fourth Indian, and the other quarter just plain meanness. He's as venomous as a rattler, as sneaking as a coyote, as bad-tempered as a bob-cat, and just about as pretty to look at as a Gila monster."

Roger laughed.

"You don't seem to love them much," he said, "but I guess that description's coming it a little strong."

"Not a blamed bit!" answered the agent, handing the boy his ticket, "an' you'll find out that the rest of the people down there are just about as fond of 'em as me. I lived down in Tombstone for some years, and I wouldn't take the whole county of Cochise for a gift unless I could teetotally banish all those cusses. Prescott ain't any lily-fingered Eastern town, by a long shot, but it's a Sunday school compared to the Pecos country, you can bet on that!"

"Well," replied the boy, nodding, "I'll try to come out of there alive, just the same."

"Hope you do, son," was the reply, "an' I'll give you jest one piece of advice which may help that hope along a lot. It's this—don't let any Greaser who has a grudge agin you get within' knifin' distance, or your camp mates will be picking out a nice chaste headstone and sending your last lovin' messages to your friends."

"All right," replied the boy cheerfully, "I'll keep it in mind."

The day following, Roger, having regretfully bidden good-by to Duke, boarded the train for the Pecos country, but the trip was so replete with wonder that there was no time for lamenting even the absence of a favorite horse. Passing through Phœnix, which a few years ago was nothing but the desolate haunt of the dying consumptive, and which, through irrigation, has become one of the garden spots of the Southwest, they came to Casa Grande. Roger had never even heard of the place, but in the observation car an elderly man, who was traveling with his son, began speaking of the wonderful ruins that lay north of the road, and casually showed that he was going to stop off and visit them. After a moment's hesitation, Roger, who had been sitting close by, turned to him.

"I beg your pardon, sir," he said, "but I felt sure you would not mind my hearing what you said about the Casa Grande ruins."

"Not at all, my boy," was the ready reply, "I am only glad if I was able to interest you."
