"Hold on!" the contractor cried to Tom's back. His cunning told him in an instant that he had made a mistake; that this man, if let go, might make trouble. "I was just foolin' you. Of course, I'll pay you full rate." Tom knew the man was lying, but he had no real proof that the contractor was breaking faith both with the union and his fellow employers; so, as he needed the money, he took the offered position and went to work the next morning. The job was a fire-engine house just being started on the upper west side of the island. The isolation of the job and the insignificance of the contractor made Tom feel there was a chance Foley might overlook him for the next two weeks. On the following Saturday morning three new men began work on the job. One of them Tom was certain he knew--a tall, lank fellow, chiefly knobs and angles, with wide, drooping shoulders and a big yellow mustache. Tom left his place at the crane of the jimmy derrick and ran down a plank into the basement to where this man and four others were rolling a round column to its place. He touched the man on the shoulder. "Your name's Petersen, ain't it?" "Yah," said the big fellow. "And you worked for a couple of days on the St. Etienne Hotel?" "Yah." Tom did his duty as prescribed by the union rules. He pointed out Petersen as a scab to the steward. Straightway the men crowded up and there was a rapid exchange of opinions. Tom and the steward wanted that a demand for Petersen's discharge be made of the contractor. But the others favored summary action, and made for where the big Swede was standing. "Get out!" they ordered. Petersen glowered at the crowd. "I lick de whole bunch!" he said with slow defiance. The men were brought to a pause by his threatening attitude. His resentful eyes turned for an instant on Tom. The men began to move forward cautiously. Then the transformation that had taken place on the St. Etienne Hotel took place again. The courage faded from him, and he turned and started up the inclined plank for the street. Jeers broke from the men. Caps and greasy gloves pelted Petersen's retreating figure. One man, the smallest of the gang, ran up the plank after him. "Do him up, Kid!" the men shouted scrambling up to the sidewalk. Kid, with showy valiance, aimed an upward blow at the Swede's head. Petersen warded off the fist with automatic ease, but made no attempt to strike back. He started away, walking sidewise, one eye on his path, one on his little assailant who kept delivering fierce blows that somehow failed to reach their mark. "If he ain't runnin' from Kid!" ejaculated the men. "Good boy, Kid!" The blows became faster and fiercer. At the corner Petersen turned back, held his foe at bay an instant, and a second time Tom felt the resentment of his eyes. Then he was driven around the corner. A minute later the little man came back, puffed out and swaggering. "What an infernal coward!" the men marveled, as they went back to work.
