In the end I answered Akeley's letter, adopting a tone of friendly interest and soliciting further particulars. His reply came almost by return mail; and contained, true to promise, a number of Kodak views of scenes and objects illustrating what he had to tell. Glancing at these pictures as I took them from the envelope, I felt a curious sense of fright and nearness to forbidden things; for in spite of the vagueness of most of them, they had a damnably suggestive power which was intensified by the fact of their being genuine photographs—actual optical links with what they portrayed, and the product of an impersonal transmitting process without prejudice, fallibility, or mendacity.
