"Hello! Yes, yes! What is it?" he cried, irritably. "Mercy Hospital! _What_?" The young physician started. "Hurt, you say? Run-away? Go on, quick!" He listened with whitening face, then broke in abruptly: "Of course he sent for me. I'll be right up." He slammed the receiver upon its hook and, seizing his hat, bolted out through a waiting-room full of patients. His car was in readiness, and he called to his chauffeur in such tones that the fellow vaulted to his seat. "Go up Madison Avenue; there's less traffic there. And for God's sake _hurry_!" During two years' service with New York's most fashionable physician the driver had never received a command like this, and he opened up his machine. A policeman warned him at Thirty-third Street and the car slowed down, at which Suydam leaned forward, crying, roughly: "To hell with regulations! There's a man dying!" The last word was jerked from him as he was snapped back into his seat. Regardless of admonitory shouts from patrolmen, the French car sang its growing song, while truck-drivers bellowed curses and pedestrians fled from crossings at the scream of its siren. A cross-town car blocked them, and the brakes screeched in agony, while Doctor Suydam was well-nigh catapulted into the street; then they were under way again, with the car leaping from speed to speed. It was the first time the driver had ever dared to disregard those upraised, white-gloved hands, and it filled his joy-riding soul with exultation. A street repair loomed ahead, whereupon, with a sickening skid, they swung into a side street; the gears clashed again, and an instant later they shot out upon Fifth Avenue. At the next corner they lay motionless in a blockade, while the motor shuddered; then they dodged through an opening where the mud-guards missed by an inch and were whirling west toward Broadway. At 109th Street a bicycle officer stared in amazement at the dwindling number beneath the rear axle, then ducked his head and began to pedal. He overhauled the speeding machine as it throbbed before the doors of Mercy Hospital, to be greeted by a grinning chauffeur who waved him toward the building and told of a doctor's urgency. Inside, Doctor Suydam, pallid of face and shaking in a most unprofessional manner, was bending over a figure in riding-clothes, the figure of a tall, muscular man who lay silent, deaf to his words of greeting.
