The Roachbacks, as the Bitter-root Grizzlies are called, are a cunning and desperate race. An old Roachback knows more about traps than half a dozen ordinary trappers; he knows more about plants and roots than a whole college of botanists. He can tell to a certainty just when and where to find each kind of grub and worm, and he knows by a whiff whether the hunter on his trail a mile away is working with guns, poison, dogs, traps, or all of them together. And he has one general rule, which is an endless puzzle to the hunter: "Whatever you decide to do, do it quickly and follow it right up." So when a trapper and a Roachback meet, the Bear at once makes up his mind to run away as hard as he can, or to rush at the man and fight to a finish. The Grizzlies of the Bad Lands did not do this: they used to stand on their dignity and growl like a thunder-storm, and so gave the hunters a chance to play their deadly lightning; and lightning is worse than thunder any day. Men can get used to growls that rumble along the ground and up one's legs to the little house where one's courage lives; but Bears cannot get used to 45-90 soft-nosed bullets, and that is why the Grizzlies of the Bad Lands were all killed off. So the hunters have learned that they never know what a Roachback will do; but they do know that he is going to be quick about it. Altogether these Bitter-root Grizzlies have solved very well the problem of life, in spite of white men, and are therefore increasing in their own wild mountains. Of course a range will hold only so many Bears, and the increase is crowded out; so that when that slim young Bald-faced Roachback found he could not hold the range he wanted, he went out perforce to seek his fortune in the world. [Illustration] He was not a big Bear, or he would not have been crowded out; but he had been trained in a good school, so that he was cunning enough to get on very well elsewhere. How he wandered down to the Salmon River Mountains and did not like them; how he traveled till he got among the barbwire fences of the Snake Plains and of course could not stay there; how a mere chance turned him from going eastward to the Park, where he might have rested; how he made for the Snake River Mountains and found more hunters than berries; how he crossed into the Tetons and looked down with disgust on the teeming man colony of Jackson's Hole, does not belong to this history of Wahb. But when Baldy Roachback crossed the Gros Ventre Range and over the Wind River Divide to the head of the Graybull, he does come into the story, just as he did into the country and the life of the Meteetsee Grizzly. The Roachback had not found a man-sign since he left Jackson's Hole, and here he was in a land of plenty of food. He feasted on all the delicacies of the season, and enjoyed the easy, brushless country till he came on one of Wahb's sign-posts. "Trespassers beware!" it said in the plainest manner. The Roachback reared up against it.
