A dozen yards or so ahead of them Andy Rawlinson and Mr. Nelson cantered up the dusty road, their horses' hoofs making the dust fly in a white cloud.

"Goodness!" sneezed Betty, extracting a small handkerchief from her pocket and applying it to her nose, "I do hope those two keep their distance. We'll be simply choked with dust."

"I wonder," said Grace, as she rubbed her dust-filled eyes, "if they don't have any rain in this part of the world."

"Of course they do; only this happens to be the dry season," said Mollie, instructively, from the heights of her superior intelligence. At least, that is what she called it.

"I'll say it's dry," grumbled Grace.

"Ooh, look," Amy interrupted ecstatically. "Isn't that a cactus over there? Oh, I've wanted all my life to see some real cacti. Now I know we're in the West."

The girls were silent for a moment, gazing out over the rolling plain—a plain studded with stunted trees and sickly-looking bushes with here and there a cactus plant for variety's sake—out to the hazy mountains beyond, serene, calm, majestic, jutting jaggedly into the dazzling blue of a cloudless sky.

"The mountains!" murmured Betty, half to herself. "How I love them. The plains are fascinating in a cruelly romantic way, but somehow the mountains make one think of hidden springs rushing swiftly into noisy foolish little brooks, of bird songs, and the smell of cool damp earth, of the crackling of dry twigs under one's feet, and the pungent woodsy smell of camp fires—but there," she broke off confusedly, as she realized the girls were regarding her with fond amusement. "I didn't mean to wax so poetic."

"It's all right, honey," said Mollie, giving her hand a warm little squeeze. "You rave right along. I know just how you feel, for I get that way myself sometimes."

"There is something mighty wonderful about the mountains," added Grace softly.
