The airplane observers picked up the smoke five minutes after the fire was lighted. The amateur operator picked up the message and notified the warden almost immediately. Twenty minutes later the warden was on the scene and the fire was extinguished. Another half hour and the case was being heard in court and sentence pronounced. Thus within an hour after the fire was started the man had been convicted and had paid his fine. He never knew how the fire was discovered and why the warden had arrived so quickly until it was all over. It mystified him, for things had happened so quickly. The warden explained to him how the observers were flying overhead with all-seeing eyes and could discern even the smallest of slashing fires. It was rather a bitter pill for the woodsman to swallow, but he had learned that when forest regulations were published it was expected that they would be obeyed.
