As we drove on, the darkness was falling, and the scenery along the road grew wilder and grander. A terrific storm had swept over these heights, and the great trees lay uptorn and prostrate in every direction, or reeled and fell against each other like drunken giants--a scene of fearful elemental violence. On the summits one sees the tan-bark oak; lower down, the white oak; and lower yet, fine specimens of yellow poplar; while from the valleys to the crests is a dense and varied undergrowth, save where the ground has been burned over, year after year, to kill it out and improve the grazing. Twenty miles to the south-east we had seen through the pale-tinted air the waving line of Jellico Mountains in Tennessee. Away to the north lay the Beaver Creek and the lower Cumberland, while in front of us rose the craggy, scowling face of Anvil Rock, commanding a view of Kentucky, Tennessee, and Virginia. The utter silence and heart-oppressing repose of primeval nature was around us. The stark white and gray trunks of the immemorial forest dead linked us to an inviolable past. The air seemed to blow upon us from over regions illimitable and unexplored, and to be fraught with unutterable suggestions. The full-moon swung itself aloft over the sharp touchings of the green with spectral pallor; and the evening-star stood lustrous on the western horizon in depths of blue as cold as a sky of Landseer, except where brushed by tremulous shadows of rose on the verge of the sunlit world. A bat wheeled upward in fantastic curves out of his undiscovered glade. And the soft tinkle of a single cow-bell far below marked the invisible spot of some lonely human habitation. By-and-by we lost sight of the heavens altogether, so dense and interlaced the forest. The descent of the hack appeared to be into a steep abyss of gloom; then all at once we broke from the edge of the woods into a flood of moonlight; at our feet were the whirling, foaming rapids of the river; in our ears was the roar of the cataract, where the bow-crowned mist rose and floated upward and away in long trailing shapes of ethereal lightness. [Illustration: MOONRISE ON CUMBERLAND RIDGE.] The Cumberland River throws itself over the rocks here with a fall of seventy feet, or a perpendicular descent of sixty-two, making a mimic but beautiful Niagara. Just below, at Eagle Falls, it drops over its precipice in a lawny cascade. The roar of the cataract, under favorable conditions, may be heard up and down stream a distance of ten or twelve miles. You will not find in mountainous Kentucky a more picturesque spot.
