The young hostess nodded, “Yes, dear, it does, but I am more concerned about Malcolm’s anxiety than I am about the disappearance of the yearlings. I do wish there was something that girls could do to help.”

Betsy had drawn near to listen. “Let’s get up just as soon as ever we can awaken,” she suggested, “and let’s try to find the wagon trails. If only I could solve this mystery, I’d be the happiest girl in all the land.”

Virginia, who understood the desert better than did her companions, even those who had visited it the year before, hesitated. Well she knew that it was very easy for even one desert-bred, to be lost in the Burning Acres. Then, noticing how truly disappointed Betsy looked, the young hostess conceded. “We can ride as far as the Three Sand Hills if you wish.” And with this Betsy had to be content, but how she did hope that they would go farther, and, Oh, if only she, Betsy Clossen, could find the caravan trail and restore the missing cattle. Her active brain was planning imaginary clews long after the others were asleep and yet, she was the first to awaken as soon as a faint grey light revealed the horizon. What would the day bring forth, she wondered.

CHAPTER V
BETSY’S FIRST RIDE

Malcolm, weary indeed with the long hard riding on the three days previous, did not waken, nor did Uncle Tex when, at a very early hour, the four girls stole out of the ranch house and, while the stars were still shining in the paling sky they skipped down to the wrangling corral. In a nearby shelter hung the saddles and Virg, with Margaret’s help, soon had the four ponies ready to ride. If Malcolm had known of their expedition, he would have insisted upon accompanying them, not knowing what dangers might await them. In fact he had intended to warn Virginia not to leave the immediate neighborhood of the ranch until he and Lucky had discovered the hiding place of the mysterious caravan, but, although he thought of it after he had retired, he reminded himself that it would be time to tell them at breakfast.

Virginia indeed had little hope of coming upon the trail of the rumored caravan, for, during the night, a sandstorm had swept across the desert and though of but brief duration, it would have obliterated whatever tracks had been visible the day before. She had thought of explaining this to the girls, but, knowing that Betsy would be greatly disappointed, she decided to ride with them at least as far as the Three Sand Hills.

This she often did, and, as the hills were surrounded by a vast waste of open desert, she knew that unless the gypsies were camped on the other side of the hills themselves, they would not come unexpectedly upon them.

Betsy, before she had left school, had expected to be timid about riding the western horses but Virg chose for her a gentle pony that was well broken and so interested was the Eastern girl in the quest upon which they were starting, that she found that she was not at all afraid.

The east was beginning to glow with pale rose and lilac when the top of the mesa was reached and Virginia, in the lead, pointed, as they all drew rein, to the Three Sand Hills that loomed dark and isolated, standing alone like sentinels on an otherwise flat expanse of desert.

Betsy looked up with glowing eyes. “It’s wonderful!” she said, “just to see this sun rise on the desert is worth a great deal, even if we don’t find a trail.”
