For years I had wished to write an historical novel of the conquest of Canada or the settlement of the United Empire loyalists and the subsequent War of 1812, but the central idea and the central character had not come to me; and without both and the driving power of a big idea and of a big character, a book did not seem to me possible. The human thing with the grip of real life was necessary. At last, as pointed out in the prefatory note of the first edition, published in the spring of 1896 by Messrs. D. Appleton & Co., of New York, and Messrs. Methuen & Co., of London, I ran across a tiny little volume in the library of Mr. George M. Fairchild, Jr., of Quebec, called the Memoirs of Major Robert Stobo. It was published by John S. Davidson, of Market Street, Pittsburgh, with an introduction by an editor who signed himself "N. B.C." The Memoirs proper contained about seventeen thousand words, the remaining three thousand words being made up of abstracts and appendices collected by the editor. The narrative was written in a very ornate and grandiloquent style, but the hero of the memoirs was so evidently a man of remarkable character, enterprise and adventure, that I saw in the few scattered bones of the story which he unfolded the skeleton of an ample historical romance. There was necessary to offset this buoyant and courageous Scotsman, adventurous and experienced, a character of the race which captured him and held him in leash till just before the taking of Quebec. I therefore found in the character of Doltaire--which was the character of Voltaire spelled with a big D--purely a creature of the imagination, one who, as the son of a peasant woman and Louis XV, should be an effective offset to Major Stobo. There was no hint of Doltaire in the Memoirs. There could not be, nor of the plot on which the story was based, because it was all imagination. Likewise, there was no mention of Alixe Duvarney in the Memoirs, nor of Bigot or Madame Cournal and all the others. They too, when not characters of the imagination, were lifted out of the history of the time; but the first germ of the story came from 'The Memoirs of Robert Stobo', and when 'The Seats of the Mighty' was first published in 'The Atlantic Monthly' the subtitle contained these words: "Being the Memoirs of Captain Robert Stobo, sometime an officer in the Virginia Regiment, and afterwards of Amherst's Regiment."
