Sara gave a short nod. "Give me my pipe, Pen, and then jolly Mrs. Flynn up."

Mrs. Flynn, whose curiosity was only equaled by her kindness of heart, was only too willing to take care of Sara. Had a caged South African lion been placed in her care she would have had the same thrill at the thought of caring for it as at watching Sara. Great stories of Sara's marvelous temper had gone about the camp. Any extra steps he caused Mrs. Flynn she felt would be more than compensated for in the delectable gossip she would pick.

Pen did not ask Jim to take her down to the Ames place. She arranged to go down with Bill Evans, who kept a hog ranch near the dam. Bill fed his hogs on the camp table scrapings and filled in odd moments "renting out" his automobile. This was a sad-looking vehicle of an early vintage, held together by binding wire and bits of sheet iron. But Bill got twenty miles an hour out of the machine and took better care of it than he did of his wife.

The Ames ranch lay in the desert valley below the dam. Two hours after they left the dam, Bill drew up before the Ames door with a rattle and a series of staccato explosions that would have done credit to an approaching army.

The trip down had been a noisy rush through multicolored ranges out onto a desert floor of brilliant yellow dotted with giant cactus, that austere sentinel of the desolate plains. Long before they left the mountain road Bill pointed out to Penelope the green spot in the desert that was the Ames ranch. The road, leaving the desert, ran along an irrigating ditch fringed with cotton woods. Beyond the road lay acre after acre of alfalfa, its peculiar living green melting far beyond in the shimmering of olive orchard and orange grove.

The ranch house was of yellow gray adobe, long and low, with a red roof. Oscar had made no attempt at beauty when he had added, year after year, room on room to the original box he had built for Jane. But he unknowingly had kept close to real art. He had built of the material of the country in the manner best suited to the exigencies of the country. The result, consequently, was satisfying to eye and taste.

The walls of a desert house must be thick, for coolness. The lines of the house must be broad and low and strong, to withstand the fearful winds of late winter and early spring. The Ames house lay comfortably on the desert as if it had grown up out of the sand and proposed to live forever. It was as natural a part of the landscape as the sentinel cactus.

Jane Ames, in a blue gingham dress, was standing in the door. She waved both hands as she recognized Pen. When the machine stopped she took Pen's bag.

"Of course I knew it was Bill's machine half an hour ago, but I didn't know my luck had changed enough to bring you."

"I can stay over night," said Pen, like a child out of school.
