The coyote problem is a serious one. Various methods of dealing with it have been in vogue since coyotes first began to like mutton. None of the methods have been entirely satisfactory, and some are signal failures. All of them combined have resulted in a partial check on the increase of coyotes in most parts of their range. Poison has probably killed the greatest number of adult animals, and in some parts of Mexico has almost destroyed some of the species, but no such success has attended its use in the United States. POISONING. Strychnine has always been a favorite weapon of hunters for wolf pelts and bounties. A half century ago hunters on the prairies killed the buffalo for its pelt, and added to their income by killing the wolves that followed the daily slaughter. A little strychnine inserted in the skinned carcass of a buffalo enabled them to secure many pelts of the gray wolf and occasionally one of the coyote; but not often the latter: he was regarded as much too shrewd to be taken by ordinary methods of poisoning. Resides, the pelt was small and not sufficiently valuable in comparison to warrant special efforts to secure it. Even in 1819 Thomas Say, who first gave a scientific name to a coyote, found this animal more abundant than the gray wolf.[F] Yet the number killed for their pelts has never been great. [Footnote F: Long's Expedition to the Rocky Mountains, p. 168, 1823.] As an illustration of the coyote's shrewdness in avoiding poisoned bails, a farmer in Oklahoma gave the writer the following experience: After butchering some hogs he poisoned a hogskin and left it with other offal for a coyote that nightly prowled about his premises. In the morning everything but the poisoned skin had been cleared away. He left it two more nights, but it remained untouched. Thinking that the animal would not eat the poisoned bait, he buried it. That night the coyote dug up the pigskin and ate it, falling a victim to its deadly contents. Since then the farmer says he has never failed to poison coyotes when he buries the bait.
