"Go on and make me!" implored Nance. "I will if you don't stand back," threatened the boy called Mac. Nance promptly stepped up to the alley gate and wiggled her fingers in a way peculiarly provocative to a juvenile enemy. "Poor white trash!" he jeered. "You stay where you belong! Don't you step on our concrete!" "Will if I want to. It's my foot. I'll put it where I like." "Bet you don't. You're afraid to." "I ain't either." "Well, _do_ it then. I dare you! Anybody that would take a--" In a second Nance had thrust her leg as far as possible between the boards that warned the public to keep out, and had planted a small alien foot firmly in the center of the soft cement. This audacious act was the signal for instant battle. With yells of indignation the choir boys hurled themselves from the fence, and descended upon their foes. Mud gave place to rocks, sticks clashed, the air resounded with war cries. Ash barrels were overturned, straying cats made flying leaps for safety, heads appeared at doorways and windows, and frantic mothers made futile efforts to quell the riot. Thus began the greatest fight ever enjoyed in Calvary Alley. It went down in neighborhood annals as the decisive clash between the classes, in which the despised swells "was learnt to know their places onct an' fer all!" For ten minutes it raged with unabated fury, then when the tide of battle began to set unmistakably in favor of the alley, parental authority waned and threats changed to cheers. Old and young united in the conviction that the Monroe Doctrine must be maintained at any cost! In and out of the subsiding pandemonium darted Nance Molloy, covered with mud from the shoestring on her hair to the rag about her toe, giving and taking blows with the best, and emitting yells of frenzied victory over every vanquished foe. Suddenly her transports were checked by a disturbing sight. At the end of the alley, locked in mortal combat, she beheld her arch-enemy, he of the brown eyes and the frilled shirt, whom the boys called Mac, sitting astride the hitherto invincible Dan Lewis, the former philosopher of the ash barrel and one of the acknowledged leaders of the Calvary Micks. It was a moment of intense chagrin for Nance, untempered by the fact that Dan's adversary was much the bigger boy. Up to this time, the whole affair had been a glorious game, but at the sight of the valiant Dan lying helpless on his back, his mouth bloody from the blows of the boy above him, the comedy changed suddenly to tragedy. With a swift charge from the rear, she flung herself upon the victor, clapping her mud-daubed hands about his eyes and dragging him backward with a force that sent them both rolling in the gutter.
