It was in the Fall of nineteen seventeen at an officers' training camp that I first became acquainted with John Carter, War Lord of Barsoom, through the pages of your novel "A Princess of Mars." The story made a profound impression upon me and while my better judgment assured me that it was but a highly imaginative piece of fiction, a suggestion of the verity of it pervaded my inner consciousness to such an extent that I found myself dreaming of Mars and John Carter, of Dejah Thoris, of Tars Tarkas and of Woola as if they had been entities of my own experience rather than the figments of your imagination.
