Joe McCaskey was a man of nerve; he held himself erect; there was defiance in the gaze which he leveled at the faces below him. But his brother Jim was not made of such stern, stuff--he was the meaner, the more cowardly of the pair--and these methodical preparations, the certainty of his own forthcoming ordeal, bred in him a desperate panic. The sight of his brother's flesh bared to the bite of the lash brought home to him the horrifying significance of a flogging, and then, as if to emphasize that significance, the executioner gave his cat-o'-nine-tails a practice swing. As the lashes hissed through the air the victim at the post stiffened rigidly, but his brother, outside the inclosure, writhed in his tracks and uttered a faint moan. Profiting by the inattention of his captors, Jim McCaskey summoned his strength and with an effort born of desperation wrenched himself free. Hands grasped at him as he bolted, bodies barred his way, but he bore them down; before the meaning of the commotion had dawned upon the crowd at large he had fought his way out and was speeding down the street. But fleet-footed men were at his heels, a roar of rage burst from the mob, and in a body it took up the chase. Down the stumpy, muddy trail went the pursuit, and every command to halt spurred the fleeing man to swifter flight. Cabin doors opened; people came running from their tents; some tried to fling themselves in the way of the escaping criminal; packers toiling up the trail heard the approaching clamor, shook off their burdens and endeavored to seize the figure that came bounding ahead of it. But Jim dodged them all. Failing in their attempt to intercept him, these newcomers joined the chase, and the fugitive, once the first frenzy of excitement had died in him, heard their footsteps gaining on him. He was stark mad by now; black terror throttled him. Then some one fired a shot; that shot was followed by others; there came a scattered fusillade, and with a mighty leap Jim McCaskey fell. He collapsed in midair; he was dead when his pursuers reached him. Mob spirit is a peculiar thing; its vagaries are difficult to explain or to analyze. Some trivial occurrence may completely destroy its temper, or again merely serve to harden it and give it edge. In this instance the escape, the flight, the short, swift pursuit and its tragic ending, had the effect, not of sobering the assembled citizens of Sheep Camp, not of satisfying their long-slumbering rage, but of inflaming it, of intoxicating them to a state of insane triumph. Like the Paris mobs that followed shouting, in the wake of the tumbrels bound for the guillotine, these men came trooping back to the scene of execution, and as they came they bellowed hoarsely and they waved their arms.
