The President paused. From the crowd in front of him came a sudden disturbance. A man sprang free of the crowd and broke through the restraining cordon of police. In his hand gleamed an ugly blue steel automatic pistol. Quickly he leveled it and fired. A puff of dust came from the Capitol. The bullet had landed a few inches from one of the lower windows, fifty feet from where the President stood. He raised his weapon for a second shot but it was never fired. The man who had come down the Capitol steps sprang forward like a cat and grasped the weapon. For a moment the two men struggled, but only for a moment. From the crowd, stunned for a moment by the sheer audacity of the attack, came a roar of rage. The police closed in about the struggling men but the crowd rolled over them like a wave. The captor shouted his identity and tried to display the gold badge of the secret service but the mob was in no state of mind to listen. The police were trampled underfoot and the would-be assassin torn from the hands of the secret service operative. Every man in reach tried to strike a blow. The secret service man was buffeted and thrown aside. Realizing that the affair had been taken out of his hands, he made his way to the rear of the Capitol where his badge gained him ready passage through the cordon of police. He entered the building and reappeared in a few moments by the side of the President. * * * * * Two hours later he leaned forward in his chair in Dr. Bird's private laboratory in the Bureau of Standards and spoke earnestly. "Dr. Bird," he said, "that bullet was never meant for the President. That man was after bigger game." The famous scientist nodded thoughtfully. "Even a very rotten pistol shot should have come closer to him," he replied. "He must have missed by a good forty feet." "He missed by a matter of inches. Doctor, that bullet struck the Capitol only two inches from a window. In that window was standing a man. The bullet was intended for the occupant of that window. I was directly behind him when he raised his weapon for a second shot and I am sure of his aim. He deliberately ignored the President and aimed again at that window. That was when I tackled him." "Who was standing there, Carnes?" "_You_ were, Doctor." Dr. Bird whistled. "Then you think that bullet was intended for me?" "I am sure of it, Doctor. That fact proves one thing to me. You are right in your idea that this whole affair is man-made and not an accident of nature. The guiding intelligence back of it fears you more than he fears anyone else and he took this means to get rid of you unobtrusively. Attention was focused on the President. Your death would have been laid to accident. It was a clever thought."
