"Looks like a scrap--do you--" "Nonsense! Come on. I divide women into those who would like to see a prize fight and admit it, and those who would like to see a prize fight and deny it!" "Gee whiz!" said Bertram. They had reached the edge of the crowd, which circled about some knot of violent struggle and gesture. "Excuse me!" He had sprung from her side and was breaking his way through. By instinct, she followed into the hole back of him, so that she found herself in the second row of spectators to a curious struggle, the details of which flashed in upon her all at once. Two laborers, gross, tanned, dirty, were fighting. They had swung side-on as the hole opened, and her glance focused itself upon the smaller of the two. He was an old man, quite gray; and down his scalp ran a stream of bright blood which trickled upon his ear. The thing which puzzled her was the action of the older man. He seemed to be hanging to the arms of his younger and sturdier opponent; also he was talking rapidly, excitedly; and she caught only one phrase. "Hit me with a nail, will you?" And just then the younger man got his arm free, and dove for the pavement--dove at precisely the same instant with Bertram Chester. Apparently, the younger fighter arrived first; he backed off from the scuffle brandishing a piece of packing box. Then she saw what the old man meant. Pointing the weapon was a nail, stained red. As this rough fury poised himself for the stroke, she took in the whole picture--a young, tall, brute man, one eye puffing from a new blow, the other blood-shot, the mouth open and dripping, the right arm raised for the murderer's blow. Bertram Chester came between as though he had risen out of the earth. His left hand, with a trained aptitude which made the motion seem the easiest thing in the world, caught the upraised wrist. The laborer ripped out an unconsidered oath and struck with his free fist at Bertram's face. Bertram evaded the blow, slipped in close. And then--in a lightning flash of speed, Bertram's right hand, which had been resting loosely by his side, shot upward. His whole body seemed to spring up behind it. The blow struck under the point of the chin. The head of the young bruiser dropped, then his shoulders, then his arms; his body sagged down upon Bertram. The champion of age shook him off; he dropped to the sidewalk. All this in a flash, in a wink. The crowd, curiously inert, as all city crowds are until the leader appears, now followed this leader. A clamor of many tongues arose--"Get a cop!" "He's killed him!" "Do him up!" A short rush of half a dozen boys toward the fallen bully met the resistance of Bertram, who had turned as though anticipating such a movement. He shoved them back and raised his hand. His eyes were bright, his face flushed, and that smile which won and commanded men had broken out on his lips.
