MY DEAR DR. VALCOUR: You gave me the Inspiration which made this story haunt me until I wrote it. Gaspard Roussillon's letter, a mildewed relic of the year 1788, which you so kindly permitted me to copy, as far as it remained legible, was the point from which my imagination, accompanied by my curiosity, set out upon a long and delightful quest. You laughed at me when I became enthusiastic regarding the possible historical importance at that ancient find, alas! fragmentary epistle; but the old saying about the beatitude of him whose cachinations are latest comes handy to me just now, and I must remind you that "I told you so." True enough, it was history pure and simple that I had in mind while enjoying the large hospitality of your gulf-side home. Gaspard Roussillon's letter then appealed to my greed for materials which would help along the making of my little book "The Story of Louisiana." Later, however, as my frequent calls upon you for both documents and suggestions have informed you, I fell to strumming a different guitar. And now to you I dedicate this historical romance of old Vincennes, as a very appropriate, however slight, recognition of your scholarly attainments, your distinguished career in a noble profession, and your descent from one of the earliest French families (if not the very earliest) long resident at that strange little post on the Wabash, now one of the most beautiful cities between the greet river and the ocean.
