When Jones was game warden of the Yellowstone National Park, he had unexampled opportunities to hunt cougars and learn their habits. All the cougars in that region of the Rockies made a rendezvous of the game preserve. Jones soon procured a pack of hounds, but as they had been trained to run deer, foxes and coyotes he had great trouble. They would break on the trail of these animals, and also on elk and antelope just when this was farthest from his wish. He soon realized that to train the hounds was a sore task. When they refused to come back at his call, he stung them with fine shot, and in this manner taught obedience. But obedience was not enough; the hounds must know how to follow and tree a lion. With this in mind, Jones decided to catch a lion alive and give his dogs practical lessons. A few days after reaching this decision, he discovered the tracks of two lions in the neighborhood of Mt. Everett. The hounds were put on the trail and followed it into an abandoned coal shaft. Jones recognized this as his opportunity, and taking his lasso and an extra rope, he crawled into the hole. Not fifteen feet from the opening sat one of the cougars, snarling and spitting. Jones promptly lassoed it, passed his end of the lasso round a side prop of the shaft, and out to the soldiers who had followed him. Instructing them not to pull till he called, he cautiously began to crawl by the cougar, with the intention of getting farther back and roping its hind leg, so as to prevent disaster when the soldiers pulled it out. He accomplished this, not without some uneasiness in regard to the second lion, and giving the word to his companions, soon had his captive hauled from the shaft and tied so tightly it could not move. Jones took the cougar and his hounds to an open place in the park, where there were trees, and prepared for a chase. Loosing the lion, he held his hounds back a moment, then let them go. Within one hundred yards the cougar climbed a tree, and the dogs saw the performance. Taking a forked stick, Jones mounted up to the cougar, caught it under the jaw with the stick, and pushed it out. There was a fight, a scramble, and the cougar dashed off to run up another tree. In this manner, he soon trained his hounds to the pink of perfection.
