ABOUT BOOK

The reader will, of course, understand that whilst the astronomical information is, in all cases, scientific fact according to our present knowledge, the story itself--as well as the attempt to describe the physical and social conditions on Mars--is purely imaginative. It is not, however, merely random imagining. In a narrative such as this some matters--as, for instance, the "air-ship," and the possibility of a voyage through space--must be taken for granted; but the other ideas are mainly logical deductions from known facts and scientific data, or legitimate inferences.
