“I knew you’d like to do that, so I got everything ready beforehand,” announced his chum. “We’ll spend to-day in sightseeing.”

They visited the Capitol and the White House, and numerous other buildings, and almost before they were aware it was evening. Then Mrs. Morr insisted upon it that her son retire early, knowing what a hard journey was before him.

The senator’s son had received word that the Mentor Construction Company had opened a temporary office at San Antonio, and the two youths were to report there before proceeding farther. The engineering corps to which they had been assigned was on the point of moving from one place to another, and they were to get definite instructions at San Antonio regarding their further movements.

“Well, good-bye and good luck to you!” said the senator, who came down to the depot with them to see them off.

“Good-bye, Dad,” answered Roger, shaking hands warmly. Dave, too, shook hands with his chum’s father.

Then, in a moment more, the two youths were off on their long journey to Texas.

“This kind of traveling is rather different from what the pioneers put up with,” remarked Roger, as the two settled themselves in their comfortable seats, they having a whole section of the sleeper 208 to themselves. “Think of what it must have been to travel thousands of miles in a boomer wagon behind a team of mules or oxen!”

“Yes, Roger, and think of being on the lookout constantly for unfriendly Indians and wild beasts,” added Dave. “I’ll tell you, when you come to consider the luxuries we enjoy these days we have much to be thankful for.”

The day’s run was a pleasant one, and the youths enjoyed it greatly. They spent the time in chatting about the prospects and in gazing at the swiftly-moving panorama to be seen from the car window.

“It’s a pity we have to sleep when there is so much to see,” was Dave’s comment, as, after having passed through Cincinnati, it grew time to retire. “I’d like very much to see what this section of the country looks like.”
