DUST was piled in thick, velvety folds on the weeds and grass of the open Kansas prairie; it lay, a thin veil on the scrawny black horses and the sharp-boned cow picketed near a covered wagon; it showered to the ground in little clouds as Mrs. Wade, a tall, spare woman, moved about a camp-fire, preparing supper in a sizzling skillet, huge iron kettle and blackened coffee-pot. Her husband, pale and gaunt, the shadow of death in his weary face and the droop of his body, sat leaning against one of the wagon wheels trying to quiet a wailing, emaciated year-old baby while little tow-headed Nellie, a vigorous child of seven, frolicked undaunted by the August heat.
