More can be done with poison, but even in this case the animal speedily learns caution by experience. When poison is first used in a district wolves are very easily killed, and perhaps almost all of them will be slain, but nowadays it is difficult to catch any but young ones in this way. Occasionally an old one will succumb, but there are always some who cannot be persuaded to touch a bait. The old she-wolves teach their cubs, as soon as they are able to walk, to avoid man’s trace in every way, and to look out for traps and poison. In consequence, though most cow-punchers carry poison with them, and are continually laying out baits, and though some men devote most of their time to poisoning for the sake of the bounty and the fur, the results are not very remunerative. [Illustration] The most successful wolf-hunter on the Little Missouri in 1896 was a man who did not rely on poison at all, but on dogs. He was a hunter named Massingale, and he always had a pack of at least twenty hounds. The number varied, for a wolf at bay is a terrible fighter, with jaws like those of a steel trap and teeth that cut like knives, so that the dogs were continually disabled and sometimes killed, and the hunter had always to be on the watch to add animals to his pack. It was not a pack that would appeal, as far as looks go, to an old huntsman, but it was thoroughly fitted for its own work. Most of the dogs were greyhounds, either rough or smooth haired, but many of them were big mongrels, and part some other breed, such as bull-dog, mastiff, Newfoundland, blood-hound, or collie. [Illustration: DOGS IN PURSUIT OF AN OLD WOLF] [Illustration] The only two necessary requisites were that the dogs should run fast and fight gamely; and in consequence they formed as wicked, hard-biting a crew as ever ran down and throttled a wolf. They were usually taken out ten at a time, and by their aid Massingale killed two hundred wolves in the course of the year. Of course there were no pretence of giving the game fair play. The wolves were killed as vermin, not for sport. The greatest havoc was in the spring-time, when the she-wolves were followed to their dens, which were sometimes holes in the earth and sometimes natural caves. There were from three to nine whelps in each litter. Some of the hounds were very fast, and they could usually overtake a young or weak wolf; but an old wolf-dog, with a good start, unless run into at once, would surely get away if he were in a running trim. Frequently, however, he was caught when he was not in running trim, for the hunter was apt to find him when he had killed a calf or taken part in dragging down a horse or steer. Under these circumstances he could not run long before the pack. [Illustration]
