paragraph: Mr. Andrews pointed to one of the oak chairs. "You sit there," he commanded, "it's reserved for members of the bar, but it's all right. You're with ME." Distinctly annoyed, slightly bewildered, the banker sank between the arms of a chair. He felt he had lost his individuality. Andrews had become his sponsor. Because of Andrews he was tolerated. Because Andrews had a pull he was permitted to sit as an equal among police-court lawyers. No longer was he Arnold Thorndike. He was merely the man "with Mr. Andrews." Then even Andrews abandoned him. "The judge'll be here in a minute, now," said the assistant district attorney, and went inside a railed enclosure in front of the judge's bench. There he greeted another assistant district attorney whose years were those of even greater indiscretion than the years of Mr. Andrews. Seated on the rail, with their hands in their pockets and their backs turned to Mr. Thorndike, they laughed and talked together. The subject of their discourse was one Mike Donlin, as he appeared in vaudeville. To Mr. Thorndike it was evident that young Andrews had entirely forgotten him. He arose, and touched his sleeve. With infinite sarcasm Mr. Thorndike began: "My engagements are not pressing, but—" A court attendant beat with his palm upon the rail. "Sit down!" whispered Andrews. "The judge is coming." Mr. Thorndike sat down. The court attendant droned loudly words Mr. Thorndike could not distinguish. There was a rustle of silk, and from a door behind him the judge stalked past.
