Daybreak, and the broad expanse of valley opening away to the south is just lighting up in chill, half-reluctant fashion, as though the night had been far too short or the revels of yester-even far too long. There is a swish and plash of rapid running waters close at hand, and here and there, where the stream is dammed by rocky ridge, the wisps of fog rise slowly into air, mingling with and adding to the prevailing tone of chilly gray. Through these fog-wreaths there stands revealed a massive barrier of wooded and rock-ribbed heights, towering aloft and shutting out the eastern sky, all their crests a-swim in floating cloud, all their rugged foothills dotted with the tentage of a sleeping army. Here, close at hand on the banks of the rushing river, a sentry paces slowly to and fro, the dew dripping from his shouldered musket and beading on his cartridge-box. The collar of his light-blue overcoat is muffled up about his ears, and his forage cap is pulled far down over his blinking eyes. As he paces southward he can see along the stream-bed camps and pale-blue ghosts of sentries pacing as wearily as himself in the wan and cheerless light. Trees are dripping with heavy charge of moisture that the faintest whiff of morning air sends showering on the bank beneath; and a little deluge of the kind coming suddenly down upon this particular sentry as he strolls under the spreading branches serves to augment the expression of general weariness and disgust, which by no means distinguishes him from his more distant fellows, but evokes no further comment than a momentary huddling of head and shoulders into the depths of the blue collar, and the briefest possible mention of the last place of all others one would be apt to connect with cooling showers. Facing about and slouching along the other way the sentry sees a picture that, had he poetry or love of the grand and beautiful in his soul, would a thousand-fold compensate him for his enforced vigil. Every moment, as the timid light grows bolder with its reinforcement from the east, there opens a vista before his eyes that few men could look upon unmoved. To his right the brawling Shenandoah, swift and swirling, goes rushing through its last rapids, as though bent on having one final "hurrah" on its own account before losing its identity in the welcoming waters of the Potomac. Hemming it in to the right--the east--and shutting out the crimson dawn are the massive bulwarks of the Loudon Heights climbing towards the changing heavens. Westward, less bold and jagged, but still a mighty barrier in almost any other companionship, are the sister heights of Bolivar, scarred and seamed with earth-work and rifle-pit, and bristling with _abattis_ and battery. Down the intervening valley plunges the Shenandoah and winds the macadam of the highway, its dust subdued for the time being; while, straight away to the front, mist-wreathed at their base from the sleeping waters of the
