In Search of the Unknown by Robert W. Chambers
Excerpt-Because it all seems so improbable--so horribly impossible to me now, sitting here safe and sane in my own library--I hesitate to record an episode which already appears to me less horrible than grotesque. Yet, unless this story is written now, I know I shall never have the courage to tell the truth about the matter--not from fear of ridicule, but because I myself shall soon cease to credit what I now know to be true. Yet scarcely a month has elapsed since I heard the stealthy purring of what I believed to be the shoaling undertow--scarcely a month ago, with my own eyes, I saw that which, even now, I am beginning to believe never existed. As for the harbor-master--and the blow I am now striking at the old order of things--But of that I shall not speak now, or later; I shall try to tell the story simply and truthfully, and let my friends testify as to my probity and the publishers of this book corroborate them.
