Far down the valley he could trace the silvery veil of vapor, revealing the course of the narrow stream, and among the dense shadows of willow and vines the fire-flies wove their webs of glimmering light. The midsummer night was still and tranquil, the silence only broken by the moan of the brook and the chirp of insects; the heavy dew-drops on tree and shrub glinted and flashed in the moonbeams that sifted through the willows in a sheen of wavering silver.
The quavering scream of a wolf on some dismal hill-top--a sound heard nightly all over the Western prairies, but one that never fails to send a cold thrill of horror through the lone traveler--startled Clifford from the momentary reverie into which he had fallen, and brought back vividly the remembrance of that night of terror and danger, which now seemed so long ago; and, as if the very thought had conjured up the spirits of the past, that well-remembered spectre, gray-robed, with snaky locks and glaring eyes, darted from among the shadows and with its bony, talon-like fingers clutched at young Warlow's throat.
Not a sound came from the lips that were drawn back from its snaggled fangs, but with its loathsome, grave-like breath full on his cheek, it closed in a death grapple with the startled and horrified youth. A wild struggle ensued; the rank vines and slender willows were trampled to the earth; and soon the combatants stood on the banks of the stream, by a deep, dark pool, and the fierce, unearthly creature, tried to force Clifford's head beneath the water.
As the fiendish, murderous intention of his assailant became apparent, young Warlow sprang back from the danger that yawned before him, and tore loose from the fury-blinded wretch, which again darted at Clifford, grappling with him in all the frenzy and desperation of a maniac.
The failing strength of the strange creature became more apparent every moment; so Clifford determined to first exhaust it by a violent struggle, then bind it with the lariat which hung at his saddle; and soon it was an easy matter for our athletic and vigorous young hero to drag the panting wretch to where his horse stood trembling with terror and wild with fright. Clifford spoke in a soothing tone, and when the horse became once more quiet, he reached for the lariat, while holding the maniac with one hand; but with a desperate wrench the spectral being tore loose from his grasp, and bounded away with a loud yell. Then, as it fled swiftly away over the prairie, at every step it would shriek like a mangled hound--the sound growing fainter, until at length it died out in silence on the grassy hills.
