Cold and still the dawn is breaking. Faint, wan, and pallid is the feeble gleam that comes peeping over the low hills far over at the east. Bare and desolate look the barren slopes on every hand. Not a tree, not a shrub of any kind can eye discover in this dim and ghostly light. All is silence, too. Even the coyotes who have set up their unearthly yelping at odd intervals during the night seem to have slunk away before the coming of the morning's sun and sought the shelter of their lurking-spots. Here on the bleak ridge, where three men, wrapped in cavalry overcoats, are lying prone, not a sound of any kind beyond an occasional muffled word is to be heard. Three hundred yards behind them, down in the valley, some thirty shadowy steeds are cropping at the dense buffalo-grass, while their riders, dismounted now, are huddled together for warmth. The occasional stamp of a hoof and the snort of some impatient charger break the silence here, but cannot be heard out at the front where the picket is lying. Another sound, soothing, monotonous, ceaseless, falls constantly upon the ear of the waking soldiers,--the rush of the swollen Platte over the rocks and gravel of the ford a quarter-mile away, the only point below the fort where the renegade Sioux can recross without swimming, and they are not yet here to try it. When they come they will find Captain Terry, with young McLean and thirty troopers, lurking behind the covering ridge, ready and willing to dispute the passage. Through the darkness of the night those good gray steeds, flitting like ghosts along the shore, have come speeding down the Platte to land their riders first at the goal, and once here, and satisfied by scrutiny of the south entrance to the ford that no Indian pony has appeared within the last twenty-four hours, Terry has posted his lookouts on the ridge, and then, having hoppled and "half-lariated" his horses, has cautioned the men to rest on their arms and not to throw off belt or spur. "There is no telling," he says, "what moment they may come along."
