Young deer slayers. Variously known as puma, mountain lion and panther, the cougar is 
America’s largest predatory beast. He is a relentless big-game enemy, and though extremely 
interesting, he must be kept well in check. Contrary to popular opinion, the cougar is seldom 
dangerous to man and will use all means to avoid him.
