Even the soft voice the mare had heard all her days did not entirely soothe her. As Virginia mounted the wind flung shut the stable door with a bang. Juno leaped as from a gunshot, and dashed away up the river to the northwest. Her rider tried in vain to change her course and quiet her spirit. The mare only surged madly forward, as if bent on outrunning the tantalizing, grinding wind. With the sense of freedom, and with the boundlessness of the plains, some old instinct of the unbridled days of by-gone generations woke to life and power in her, and with the bit between her teeth, she swept away in unrestrained speed. Virginia was a skilled horsewoman, and she had no fear for herself, so she held the reins and kept her place. "I can go wherever you can, you foolish Juno," she cried, giving herself up to the exhilarating ride. "We'll stay together to the end of the race, and we will get it out of our systems once for all, and come back 'plains-broke.'" Beyond a westward sweeping curve of the river's course the chase became a climb up a long slope that grew steeper and steeper, cutting off the view of the stream. Here Juno's speed slackened, then dropped into a steady canter, as she listened for a command to turn back. "We'll go on to the edge of that bluff, lady, now we are here, and see what is across the river," Virginia said. "Then we will hurry home to Asher and prairie hay." When they came at last over a rough shale outcrop to the highest headland, the river bed lay between its base and a barren waste of sand dunes, with broad grassy regions beyond them spreading southward. The view from the bluff's top was magnificent. Virginia held Juno to the place and looked in wonder at the vast southwest on this strange September afternoon. Across a reach of level land, miles wide, a prairie fire was sweeping in the majesty of mastery. The lurid flames leaped skyward, while roll on surging roll of black smoke-waves, with folds of gray ashes smothering between, poured out along the horizon. Beyond the fire was the dark blue storm-cloud, banded across the front by the hail mark of coppery green. Virginia sat enchanted by the grandeur of the scene. The veil had fallen from her head, and with white face and fascinated eyes, she watched the glowing fury, a graceful rider on a graceful black horse, on the crest of the lone headland outlined against the sky. Suddenly the terror of it broke upon her. She was miles from the cabin with its double fireguard. Asher had said such fires could leap rivers. Between her and safety were many level banks where the sandy stream bed was narrow, and many grassy stretches where there was no water at all.
