It was in the winter of 1892, when on a visit to French Canada, that I made up my mind I would write the volume which the public knows as 'The Seats of the Mighty,' but I did not begin the composition until early in 1894. It was finished by the beginning of February, 1895, and began to appear in 'The Atlantic Monthly' in March of that year. It was not my first attempt at historical fiction, because I had written 'The Trail of the Sword' in the year 1893, but it was the first effort on an ambitious scale, and the writing of it was attended with as much searching of heart as enthusiasm. I had long been saturated by the early history of French Canada, as perhaps 'The Trail of the Sword' bore witness, and particularly of the period of the Conquest, and I longed for a subject which would, in effect, compel me to write; for I have strong views upon this business of compulsion in the mind of the writer. Unless a thing has seized a man, has obsessed him, and he feels that it excludes all other temptations to his talent or his genius, his book will not convince. Before all else he must himself be overpowered by the insistence of his subject, then intoxicated with his idea, and, being still possessed, become master of his material while remaining the slave of his subject. I believe that every book which has taken hold of the public has represented a kind of self-hypnotism on the part of the writer. I am further convinced that the book which absorbs the author, which possesses him as he writes it, has the effect of isolating him into an atmosphere which is not sleep, and which is not absolute wakefulness, but a place between the two, where the working world is indistinct and the mind is swept along a flood submerging the self-conscious but not drowning into unconsciousness. Such, at any rate, is my own experience. I am convinced that the books of mine which have had so many friends as this book, 'The Seats of the Mighty', has had in the English-speaking world were written in just such conditions of temperamental isolation or absorption. First the subject, which must of itself have driving power, then the main character, which becomes a law working out its own destiny; and the subject in my own work has always been translatable into a phrase. Nearly every one of my books has always been reducible to its title.
