“They’d be delighted to be asked to the professor’s house, even with you out of the question, which I should not admit. Moreover, my dear Shirley, how do you know that by that time a senior girl would be interesting? Now the reverend seniors are often known to have the most serious cases of their college career with sophomores, or even freshmen girls.”

“That is so. Good. I’ll know all the freshmen girls, perhaps, and I know some of the sophomore girls as it is. Just pick out one that Aunt Anne will welcome into the family!”

“That remains to be seen, Shirley. Now, look here. Let’s plan what we do when we get to Denver.” Dick pulled from his pocket one of the illustrated advertisements, published by the railroad companies. Everything else was soon forgotten in studying Colorado and its possibilities.

From that time on there was one delightful panorama of prairie, irrigating ditches, rivers, mountains, with rides among the foothills and climbs to the heights; of new birds and flowers and trees; of unafraid wild animals in the national parks; of snowy summits; of glaciers in Glacier Park and sure-footed horses on narrow trails. Shirley was not afraid to go into quiet raptures over dashing mountain streams, all the scenes so new and inspiring to her, and each new expedition. Mrs. Lytton declared that it was “as stimulating as a cup of coffee” to meet Shirley’s eagerness every morning.

“Never having had a daughter, Shirley, I did not know what I had missed, till this trip. Dick could not be spared, but I wish that we could adopt you.”

“I never made a good girl, did I?” queried Dick.

“You are a fine son,” said his mother, “and that is enough for me.”

Shirley was glad of that little speech of compliment from her cousin Molly. Thoroughly appreciating the privilege of this trip with them, she had tried in every way to make her cousins glad that she had come. There were many little ways in which she could be of service, and when they were out together, as they sometimes were without the gentlemen, they were as jolly as two girls. Mrs. Lytton was active and strong, taking part in all the rides upon the narrow trails as bravely as any of them.

One delightful experience followed another. They grew weary at times, to be sure, and there were some narrowly averted accidents, but no calamity occurred to mar their trip. When it was wise to let time intervene between undertakings, they merely tarried a little longer in some camp or hotel until they felt like resuming the onward way. They met many friendly people at different places and with the informality of American tourists, they joined forces for some trip, or discussed frankly the problems of a common country. There was one group of girls, traveling with two chaperons, who were attracted to Shirley. Their companionship made the trip through the Yellowstone lively, for they often found themselves upon the same ’bus. Dick, too, attached a young man of about his own age, a student in a different university.

But it was not until they had reached a hotel in the big and wonderful state of Washington that Shirley saw her double.
