J.A. Hunter was an African big game guide and was paid by governments to hunt man killing animals. I think he was still active in to the 1940's. He used to sit in low trees to kill problem leapords and usually smoked cigarettes while doing so. When asked if the cats might smell the cigarette smoke he replied " If they can smell the cigarette, they can smell you". I used to trap a lot when I was a kid and you can believe it.
