In the Black Rim country March is a month of raw winds and cold rains, with sleet and snow and storm clouds tumbling high in the West and spreading to the East, where they hang lowering at the earth and then return to empty their burden of moisture upon the shrinking live things below. In the thinly settled places March is also the time when children go shivering to school, harried by weather that has lost a little of its deadliness. In January and February their lives would not be safe from sudden blizzards, but by the middle of March they may venture forth upon the quest of learning. Black Rim country was at best but scantily supplied with schools, and on the Devil's Tooth range seven young Americans--three of them adopted from Sweden--were in danger of growing up in deplorable ignorance of what learning lies hidden in books. A twelve-mile stretch of country had neither schoolhouse, teacher nor school officers empowered to establish a school. Until the Swedish family moved into a shack on the AJ ranch there had not been children enough to make a teacher worth while. But the Swedish family thirsted for knowledge of the English language, and their lamenting awoke the father of four purely range-bred products to a sense of duty toward his offspring. Wherefore Mary Hope Douglas, home from two winters in Pocatello, where she had lived with a cousin twice removed and had gone to school and had learned much, was one day invited to teach a school in the Devil's Tooth neighborhood. True, there was no schoolhouse, but there was a deserted old shack on the road to Jumpoff. A few benches and a stove and table would transform it into a seat of learning, and there were an old shed and corral where the pupils might keep their saddle horses during school hours. She would be paid five dollars a month per head, Jim Boyle of the AJ further explained. Seven "heads" at five dollars each would amount to thirty-five dollars a month, and Mary Hope felt her heart jump at the prospect of earning so much money of her own. Moreover, to teach school had long been her secret ambition, the solid foundation of many an air castle. She forthwith consented to become the very first school-teacher in the Devil's Tooth neighborhood, which hoped some day to become a real school district. She would have to ride five miles every morning and evening, and her morning ride would carry her five miles nearer the Lorrigan ranch, two of them along their direct trail to Jumpoff. Mary Hope would never admit to herself that this small detail interested her, but she thought of it the moment Jim Boyle suggested the old Whipple shack as a schoolhouse.
