Virg laughed. “I’m afraid you are going to be disappointed in us, Betsy. You’ll find V. M. really quite tame if you have been reading Wild West stories.” Then Margaret said quietly to her berth companion, “I do wish something exciting would happen the moment we arrive, don’t you, Virg?”

The older girl smiled but shook her sunny head. “No need to wish for that these days, dear. Life in Arizona is not nearly as thrilling as it is in the city of New York, if one can believe the newspapers.”

“Don’t tell Betsy, for if she thinks it is to be too commonplace, it will take all the thrill of expectancy out of it for her. You know she is never really enjoying herself unless there is a mystery to unravel or some adventure awaiting her.”

Fifteen minutes later the four girls were in the dining car.

Betsy beamed on her companions. The early morning sun falling on her red-brown hair made it shine like burnished gold.

“Even your freckles look gilded this morning,” Barbara teased.

The pug nose of the youngest wrinkled at her tormentor, then with an excited little squeal she exclaimed, “Oh, isn’t the desert just gloriously lonesome looking? Those mountains over there are so bleak and gray and the canons so dark! I can’t see a living thing anywhere, can you?”

Margaret, being questioned, peered out at the wide sandy waste of desert stretching to the distant mountains that rose grim, gray and forbidding. Here and there a clump of greasewood or of mesquite was half buried in mounds of sand that the frequent whirlwinds had left.

Betsy shivered. “Girls,” she said solemnly, “the very scene teems with mystery. I just feel sure that an exciting adventure is about to begin at most any moment. The setting is perfect for one. I’m going to watch that sandhill over there as long as it’s in sight. I expect to see a Mexican bandit peer around it and utter a shrill cry which will mean—”

“Do the young ladies wish oatmeal this morning?” It was the suave waiter who had interrupted, and although the girls gave their orders with solemn faces, they laughed merrily when they were again alone.
