There are certain wild animals which when hard pressed by severe cold and hunger, will raid the farmers and ranchmen's yards, killing fowls and stock. There however, are no animals that destroy so much stock as wolves and coyotes as they largely live upon the property of farmers, settlers and ranchmen to which they add game as they can get it. While these animals are trapped, shot, poisoned, hunted with dogs, etc., their numbers, in some states, seem to be on the increase rather than the decrease in face of the fact that heavy bounties are offered. The fact that wolf and coyote scalps command a bounty, in many states, and in addition their pelts are valuable, makes the hunting and trapping of these animals of no little importance. One thing that has helped to keep the members of these "howlers" so numerous is the fact that they are among the shrewdest animal in America. The day of their extermination is, no doubt, far in the distance. This book contains much of value to those who expect to follow the business of catching wolves and coyotes.
