Despite the incredible nature of what he claimed, I could not help at once taking Akeley more seriously than I had taken any of the other challengers of my views. For one thing, he was really close to the actual phenomena—visible and tangible—that he speculated so grotesquely about; and for another thing, he was amazingly willing to leave his conclusions in a tentative state like a true man of science. He had no personal preferences to advance, and was always guided by what he took to be solid evidence. Of course I began by considering him mistaken, but gave him credit for being intelligently mistaken; and at no time did I emulate some of his friends in attributing his ideas, and his fear of the lonely green hills, to insanity. I could see that there was a great deal to the man, and knew that what he reported must surely come from strange circumstance deserving investigation, however little it might have to do with the fantastic causes he assigned. Later on I received from him certain material proofs which placed the matter on a somewhat different and bewilderingly bizarre basis.
