Published in 1913. From the Writer's Preface: The thought that the world of man, and the higher world to which those who were men have gone are not completely and irrevocably shut of from one another by the death of man's body, is made familiar to us today by some of the foremost workers and writers in science and literature. And that communication between the two worlds is not only possible, but an actual fact, is believed by many who openly avow it, and by many more who hesitate to acknowledge it for fear of unsympathetic criticism. The wish to hear from the world beyond earth is a natural wish, and sometimes that wish becomes a longing that must seek satisfaction.
