Comes a day when the young fellows refuse to be hooked and hectored to the rear! Then one of the boldest braces himself, circling and guarding and wheeling and keeping his lowered horns in line with the head of the older rival. That is the buffalo challenge! And there presently follows a bellowing like the rumbling of distant thunder, each keeping his eye on the other, circling and guarding and countering each other's moves, like fencers with foils. When one charges, the other wheels to meet the charge straight in front; and with a crash the horns are locked. It is then a contest of strength against strength, dexterity against dexterity. Not unusually the older brute goes into a fury from sheer amazement at the younger's presumption. His guarded charges become blind rushes, and he soon finds himself on the end of a pair of piercing horns. As soon as the rumbling and pawing began, Colonel Bedson used to send his herders out on the fleetest buffalo ponies to part the contestants; for, like the king of beasts that he is, the buffalo does not know how to surrender. He fights till he can fight no more; and if he is not killed, is likely to be mangled, a deposed king, whipped and broken-spirited and relegated to the fag-end of the trail, where he drags lamely after the subjects he once ruled. Some day the barking of a prairie-dog, the rustle of a leaf, the shadow of a cloud, startles a giddy young cow. She throws up her head and is off. There is a stampede--myriad forms lumbering over the earth till the ground rocks and nothing remains of the buffalo herd but the smoking dust of the far horizon--nothing but the poor, old, deposed king, too weak to keep up the pace, feeble with fear, trembling at his own shadow, leaping in terror at a leaf blown by the wind. After that the end is near, and the old buffalo must realize that fact as plainly as a human being would. Has he roamed the plains and guarded the calves from sleuths of the trail and seen the devourers leap on a fallen comrade before death has come, and yet does not know what those vague, gray forms are, always hovering behind him, always sneaking to the crest of a hill when he hides in the valley, always skulking through the prairie grass when he goes to a lookout on the crest of the hill, always stopping when he stops, creeping closer when he lies down, scuttling when he wheels, snapping at his heels when he stoops for a drink? If the buffalo did not know what these creatures meant, he would not have spent his entire life from calfhood guarding against them. But he does know; and therein lies the tragedy of the old king's end. He invariably seeks out some steep background where he can take his last stand against the wolves with a face to the foe. But the end is inevitable.
