Bear in mind closely that I did not see any actual visual horror at the end. To say that a mental shock was the cause of what I inferred - that last straw which sent me racing out of the lonely Akeley farmhouse and through the wild domed hills of Vermont in a commandeered motor at night - is to ignore the plainest facts of my final experience. Notwithstanding the deep things I saw and heard, and the admitted vividness the impression produced on me by these things, I cannot prove even now whether I was right or wrong in my hideous inference. For after all Akeley's disappearance establishes nothing. People found nothing amiss in his house despite the bullet-marks on the outside and inside. It was just as though he had walked out casually for a ramble in the hills and failed to return. There was not even a sign that a guest had been there, or that those horrible cylinders and machines had been stored in the study. That he had mortally feared the crowded green hills and endless trickle of brooks among which he had been born and reared, means nothing at all, either; for thousands are subject to just such morbid fears. Eccentricity, moreover, could easily account for his strange acts and apprehensions toward the last.
