This theme, which lay outside my plan to depict the West, had long demanded to be written, and I now set about it with vigor. As a matter of fact, I knew a great deal about mediums, for at one time I had been a member of the Council of the American Psychical Society, and as a special committee on slate writing and other psychical phenomena had conducted many experiments. I had in my mind (and in my notebooks) a mass of material which formed the background of my story, The Tyranny of the Dark. It made a creditable serial and a fairly successful book, but it will probably not count as largely in my record as "Martha's Fireplace," a short story which I wrote at about the same time. I do not regret having done this novel, because at the moment it seemed very much worth while, but I was fully aware, even then, that it had a much narrower appeal than either Hesper or The Captain of the Gray Horse Troop.

In the midst of my work on this book our good friends, Mary and Fred Easton, invited us to go with them, in their houseboat, on a trip to the World's Fair in St. Louis. Mrs. Easton offered to take Mary Isabel and her nurse into her own lovely home during our absence, and as Zulime needed the outing we joined the party.

It was a beautiful experience, a kind of dream journey, luxurious, effortless, silent and suggestive,—suggestive of the great river as it was in the time of Dubuque. Sometimes for an hour or more we lost sight of the railway, and the primitive loneliness of the stream awed and humbled us.

For ten days we sailed in such luxury as I had never known before; and when we reached home again it was the splendor of the stream and not the marvels of the Fair which had permanently enriched me. I have forgotten almost every feature of the exhibition, but the sunset light falling athwart the valleys and lighting the sand-bars into burning gold fills my memory to this day.

Here I must make another confession. Up to this time our big living-room had no fireplace. I had thrown out bay-windows, tacked on porches, and constructed bathrooms; but the most vital of all the requisites of a homestead was still lacking. We had no hearth and no outside chimney.

A fireplace was one of the possessions which I really envied my friends. I had never said, "I wish I had Bacheller's house," but I longed to duplicate his fireplace.

Like most of my generation in the West I had been raised beside a stove, with only one early memory of a fireplace, that in my Uncle David's home, in the glow of which, nearly forty years before, I had lain one Thanksgiving night to hear him play the violin—a memory of sweetest quality to me even now. Zulime's childhood had been almost equally bare. She had hung her Christmas stockings before a radiator, as I had strung mine on the wall, behind the kitchen stove. Now suddenly with a small daughter to think of, we both began to long for a fireplace with a desire which led at last toward action—on my part, Zulime was hesitant.

"As our stay in the Old Homestead comes always during the summer, it seems a wilful extravagance to put our hard-earned dollars into an improvement which a renter would consider a nuisance," she argued.

"Nevertheless I'm going to build a fireplace," I replied.

"You mustn't think of it," she protested.
