But if the most disturbing of all the views was that of the footprint, the most curiously suggestive was that of the great black stone found in the Round Hill woods. Akeley had photographed it on what was evidently his study table, for I could see rows of books and a bust of Milton in the background. The thing, as nearly as one might guess, had faced the camera vertically with a somewhat irregularly curved surface of one by two feet; but to say anything definite about that surface, or about the general shape of the whole mass, almost defies the power of language. What outlandish geometrical principles had guided its cutting—for artificially cut it surely was—I could not even begin to guess; and never before had I seen anything which struck me as so strangely and unmistakably alien to this world. Of the hieroglyphics on the surface I could discern very few, but one or two that I did see gave rather a shock. Of course they might be fraudulent, for others besides myself had read the monstrous and abhorred Necronomicon of the mad Arab Abdul Alhazred; but it nevertheless made me shiver to recognise certain ideographs which study had taught me to link with the most blood-curdling and blasphemous whispers of things that had had a kind of mad half-existence before the earth and the other inner worlds of the solar system were made.
