I have said that there were things in some of Akeley’s letters—especially the second and most voluminous one—which I would not dare to quote or even form into words on paper. This hesitancy applies with still greater force to the things I heard whispered that evening in the darkened room among the lonely hills. Of the extent of the cosmic horrors unfolded by that raucous voice I cannot even hint. He had known hideous things before, but what he had learned since making his pact with the Outside Things was almost too much for sanity to bear. Even now I absolutely refused to believe what he implied about the constitution of ultimate infinity, the juxtaposition of dimensions, and the frightful position of our known cosmos of space and time in the unending chain of linked cosmos-atoms which makes up the immediate super-cosmos of curves, angles, and material and semi-material electronic organisation.
