"I could see," the older man said, "that the Titus Canyon matter worked a little on your nerves. Now, I don't want you to feel that you must get hard, for you will find that the finest and most daring men in the world are often as tender as a woman, but it contains a most important lesson for you."
"And that is?" queried Roger.
"That it is only the fool who over-estimates his own strength."
CHAPTER IX
A FIRST-CLASS BUCKING MULE
As there was yet a month to elapse before Roger's "engagement with the sun," as Masseth had called it, and the journey to the Grand Canyon would not take more than eight or nine days, the boy felt little desirous either of waiting about the desert country or of going back to the Canyon ahead of time. It was practically a vacation for him, he had plenty of money in his pocket, a good horse between his knees, the prestige of a government appointment at his back, and the recollection of the gloomy Mohave country to wipe out.
The reconnoissance party had left him at Olancha, at the southern extremity of Owens Lake, a land of black volcanic lava and great beds of tuff. After the dazzling white of salt and borate deposits; the great sheets of black lava, and the heights of the Sierra Nevada behind, formed so strong a contrast that Roger could hardly believe that the two were but a couple of days' ride from each other. Towering over all, moreover, could be seen Mt. Whitney, the sentinel peak of the southern end of the Sierra, snow-capped and majestic, and Roger conceived the idea of riding thitherward to gain some idea of the life and scenery of the mountain-side.
A few hours' ride brought him to Lone Pine, where he put up for the night. In the course of casual conversation with some of the men in the little frame hotel, Roger mentioned that he was with the Geological Survey. This announcement he had found it necessary to make in a number of instances, for in that Western country a man's business is not regarded as a matter especially to be kept secret.
"Sho!" said one of the men, just in from a big cattle ranch. "I presoom, then, that you propose to hitch up with that peak-climbin' outfit?"
"Is there a geological reconnoissance party near here, then?" queried Roger interestedly.
