The only response to this appeal was another swerve on the part of the runaway, in avoiding which Philip nearly cannoned into a tree at the side of the road. The gentleman with the beard appeared to have lost his head altogether. His efforts to avoid disaster were now limited to swearing volubly and blowing his horn. Philip noted that the side-brake was full on; but it seemed to have little effect in checking the car. "Stick to your _wheel_, you fool!" he shouted with the full strength of his lungs. The gentleman responded with a fresh outburst of vocal and instrumental exuberance. But suddenly, just as Philip shot ahead, the girl in the blue veil leaned over and gripped the wheel in her two hands. Her parent immediately relinquished his hold altogether, and devoted his undivided attention to the horn. Then followed the fullest and most eventful minute of Philip's life. He was ahead now--going perhaps fifty miles an hour, but clear in front of the other car. He knew he must act at once, for there was barely half a mile of straight road left, and there were two sharp turns at the foot of the hill. What he had to do must be done instantaneously, and called for superb driving. He wondered if the girl behind could hold on long enough to give him a chance. To steer a car steadily from any position except the driver's seat is a difficult enough performance, but to accomplish it when the seat is occupied by a gesticulating lunatic is almost a physical impossibility. Still, Philip had had time to note the prompt and decisive way in which this girl had grasped his purpose and carried out his instructions. He felt somehow that those small gloved hands could be trusted to cling gamely on until the end of all things. Glancing back, he saw that the other car was now right behind him--seven yards or so. The moment had come--the inventor's moment. "I told Timothy it would stop a motor-bus," he observed to himself. "We'll see if it will stop two cars!" The Brake was controlled by a switch upon the steering-pillar. The farther the switch was pulled over the stronger became the current which supplied the Brake's magnetic force. But it was not required yet. Philip hastily jammed on the side-brake, which, though it could not check, sensibly moderated the headlong speed of his car; and then, getting both hands back to the steering-wheel, braced himself, and leaning well back, waited for the impact of the runaway. It came, but not too severely. By good luck or good management the pursuing car struck Philip's fairly and squarely in the back, and the two raced on together down the hill, locked together like engine and tender, the sorely handicapped little _chauffeuse_ behind exerting all her small strength to keep her leading wheels from slewing round. The shock of collision, coming where it did, sent a thrill of satisfaction coursing up Philip's spine.
