There was no longer any noise audible, and I drew the door inward, never dreaming of danger. Suddenly, with a fierce, wild spring out of the dark, a huge body hurled itself directly at my throat, striking with such headlong impetus that I went backward as if shot, crashing against the table, then to the floor, dropping my weapon as I fell. There was no noise, no sound, while for an instant, with strength of sheer desperation, I held back the snapping jaws that breathed hot fire into my very face. With a bound backward of its great body the beast jerked free from my grip, and the next instant had sunk its dripping fangs, deep and hard, into the flesh of my shoulder. As the intense pain shot through me, my right hand, driven with all the force I could muster, caught the monster once, twice, full in the throat, but tighter and tighter those clinched jaws locked, until it seemed as if every bone between them must be ground to powder. Even as I grasped the lower jaw, seeking vainly to wrench it loose, I heard the girl scream in sudden afright. “Quick!” I gasped desperately. “Get my revolver there on the floor, and use it--but for God's sake keep down; don't let the brute see you.” She must have heard, but there was no response, although her crying ceased. Yet my own struggle to rid myself of that crushing weight and those iron jaws drowned all other sounds, drove all other thoughts from me. I doubt if what I now record occupied a minute; but God protect me from ever having to experience such another minute! I continued to struggle in desperate hopelessness with single hand, in vain endeavor to wrench loose that awful grip upon my shoulder. Every movement I made was an agony, an inexpressible torture, but the very intensity of pain kept me from faintness, as the maddened beast tore deeper and deeper into the quivering flesh. With knee bent double beneath me I succeeded in turning partially upon one side, lifting the entire weight of the animal as I did so; but no degree of force I could exert would loosen those set jaws. There was no growling, no savage snarling, no sound of any kind,--just that fierce, desperate, silent struggle for life in the darkness. Every muscle of my body began to weaken from the strain, my eyes blurred, faintness swept over me, I felt my brain reeling, when there burst a vivid flash of flame within a foot of my face, singeing my forehead; then followed a deafening report, and the huge brute sprang backward with a snarl of pain, his teeth clicking together like cogs of steel. Then he stiffened and fell prone across me, a dead, inert weight, pinning me breathless to the floor.
