Clarence E. Mulford, The Coming of Cassidy — I : The Coming of Cassidy (1913)
“ The hunter, gripping the rifle firmly, looked into the angry eyes of the other, and slowly obeyed. Bill, watching the rifle intently, forthwith learned a lesson he never forgot: never to watch a gun, but the eyes of the man who has it. The left hand of the hunter seemed to melt into smoke, and Bill, firing at the same instant, blundered into a hit when his surprise and carelessness should have cost him dearly. His bullet, missing its intended mark by inches, struck the still moving Colt of the other, knocking it into the air and numbing the hand that held it. ”
