The Gila River cutting straight across the southern portion of Arizona, from the Alkali flats on the east to the Colorado at Yuma on the west, flowed then its whole course through desolation. Sometimes cottonwoods and sycamore trees rose in the bottom, and there was a patch of green around some irrigated land. But, for the most part, the basin was a waste of glittering sand and white dust, and beyond, the low hills, bare of every plant save a few stunted wild flowers, cacti and sage, greasewood and mesquite, rolled for miles and miles of barrenness. The chicken hawk and crow sailed through the fiercely blue sky, the air waved and quivered with incredible heat. At night malaria rose from the ground, the coyote barked and whined at the light of the brilliant stars, and the polecat prowled deliberately. Here, toward the eastern part of the territory, the government had portioned off the San Carlos Agency for its Apache wards, and some thirty miles away, not far from the banks of the river, Camp Thomas for its faithful soldiery. On a day when the mercury registered 120 degrees, Felipa Landor drove into the camp. Her life, since her marriage three years before, had been the usual nomadic one of the place and circumstances, rarely so much as a twelvemonth in one place, never certain for one day where the next would find her. Recently Landor had been stationed at the headquarters of the Department of Arizona. But Felipa had made no complaint whatever at having to leave the gayest post in the territories for the most God-forsaken, and she refused flatly to go East. "I can stand anything that you can," she told her husband when he suggested it, which was apparently true enough, for now, in a heat that was playing out the very mules, covered as she was with powdery, irritating dust, she was quite cheerful as he helped her from the ambulance. She stood looking round the post, across the white-hot parade ground, to the adobe barracks and the sutler's store. Then she turned and considered the officers' quarters. They were a row of hospital, wall, and A tents, floored with rough boards and sheltered by ramadas of willow branches. In the middle of the line there was a one-room mud hut. This, with the tents back of it, was her home. Landor had fitted up the hut with Navajo blankets, Indian baskets, dolls, saddle bags, war bonnets, and quivers; with stuffed birds and framed chromos, camp-chairs and some rough quartermaster's furniture. A gray blanket, with a yellow Q. M. D. in the centre, kept the glare out at the window, and the room was cool enough. One advantage of adobe--and it has others--is that it retains all summer the winter cold, and all winter the summer heat.
