Dan Failing had been studying nature on the high ridges; and he went home by a back trail that led to old Bald Mountain. Many a man of longer residence in the mountains wouldn't have cared to strike off through the thickets with no guide except his own sense of direction. The ridges are too many, and they look too much alike. It is very easy to walk in a great circle--because one leg tires before the other--with no hope whatever of anything except the spirit ever rising above the barrier of the pines. But Dan always knew exactly where he was. It was part of his inheritance from his frontiersmen ancestors, and it freed his wings in the hills. The trail was just a narrow serpent in the brush; and it had not been made by gangs of laborers, working with shovels and picks. Possibly half a dozen white men, in all, had ever walked along it. It was just the path of the wild creatures, worn down by hoof and paw and cushion since the young days of the world. It was covered, like a sheep lane, with little slit triangles in the yellow dirt. Some of them were hardly larger than the print of a man's thumb, and they went all the way up to a great imprint that Dan could scarcely cover with his open hand. All manner of deer, from seasonal fawns with spotted coats and wide, startled eyes to the great bull elk, monarch of the forest, had passed that way before him. Once he found the traces of an old kill, where a cougar had dined and from which the buzzards had but newly departed. And once he saw where Woof had left his challenge in the bark of a great pine. This is a very common thing for Woof to do,--to go about leaving challenges as if he were the most warlike creature in the world. In reality, he never fights until he is driven to it, and then his big, furry arms turn out to be steel compressors of the first order; he is patient and good-natured and ordinarily all he wants to do is sleep in the leaves and grunt and soliloquize and hunt berries. But woe to the man or beast who meets him in a rough-and-tumble fight. Unlike his great cousin the Grizzly, that American Adamzad that not only walks like a man but kills cattle like a butcher, he almost never eats meat. No one ever pays any attention to his challenges either, and likely he never thought any one would. They seemed to be the result of an inherited tendency with him, just as much as to grow drowsy in winter, or to scratch fleas from his furry hide.
