"O my God! my God! have mercy!" Dick buries his face in his hands, as he clings desperately to the smooth white-oak trunk. A strange, wild strain, like a detached chord of a vesper melody, sounds above him! It is the whippoorwill--steadily, continuously, entrancingly the dulcet measure is taken up and echoed, until the slough of despond seems transformed into a varying diapason of melancholy minstrelsy. He dares not raise his head. It will vanish if he moves. He crouches, panting, almost exultant, in the sense of recovered faculties, or rather the suspension of numbing fear. How long will it last? He must move; his limbs are cramped and aching. He raises his head. Mortal powers! the torch is flickering into ashes! Another instant and he will be in the dark. Dare he move? Dare he seek the distant pine, between him and which the black surface of the murky sheet shines, dotted with uncanny growth and reptilian things? Yes; anything is better than the hideous darkness of this hideous place. The horse he rode has broken his leash and comes to him with a gentle whinny, as if asking why the delay in such a place. "Blessed, blessed God, that made a beast so human!" He caresses it, he clings to its neck and calls to it piteously. Ah, yes; the dying light. He must renew it. He slips down upon the bare back and urges the patient beast across the brackish morass. Ah, this is life again! He is not alone. This noble beast is human. It crops the tender leaves confidingly, and swings its head as much as to say: "Don't fear, Dick; Fin here. I'll stand by you; I don't forget the pains you took to get me water, and that particularly toothsome measure of oats you cribbed in the rebel barn near Williamsburg!" But the pine knot that will burn is not so easily found. Dick was forced to go a long way before he came upon the resinous sort. He brought back a supply, having taken the precaution to provide matches in order to secure his way back. The quest had to some extent lessened the morbid or supernatural forms of his terrors. They all returned, however, when, having dismounted, he forgot to tie the horse, and it wandered off in search of herbage. He called, but the beast made no sign of returning. Alone again. Alone in the night; spectral forms about him; the sleeping man adding to the ghostliness of the scene by his incoherent mutterings, his hideous, gulping breath, his ghastly, blood-curdling outcries. Then through the gloom the shining outlines of the white oak, like shreds of shrouds hung on funeral foliage. Ah! he would go mad--he must break the brutish sleep of the sick man.
