The enterprise of Messrs. T. Nelson & Sons and the friendly accommodation of Messrs. Macmillan render possible this collection in one cover of all the short stories by me that I care for anyone to read again. Except for the two series of linked incidents that make up the bulk of the book called Tales of Space and Time, no short story of mine of the slightest merit is excluded from this volume. Many of very questionable merit find a place; it is an inclusive and not an exclusive gathering. And the task of selection and revision brings home to me with something of the effect of discovery that I was once an industrious writer of short stories, and that I am no longer anything of the kind. I have not written one now for quite a long time and in the past five or six years I have made scarcely one a year. The bulk of the fifty or sixty tales from which this present three-and-thirty have been chosen dates from the last century.
