I have often thought that to this training of my tramp days is due much of my success as a story-writer. In order to get the food whereby I lived, I was compelled to tell tales that rang true. At the back door, out of inexorable necessity, is developed the convincingness and sincerity laid down by all authorities on the art of the short-story. Also, I quite believe it was my tramp-apprenticeship that made a realist out of me. Realism constitutes the only goods one can exchange at the kitchen door for grub.
After all, art is only consummate artfulness, and artfulness saves many a "story." I remember lying in a police station at Winnipeg, Manitoba. I was bound west over the Canadian Pacific. Of course, the police wanted my story, and I gave it to them--on the spur of the moment.
