Man is by instinct and tradition a hunter, and there is no sport so thrilling as man-hunting, especially if the hunted be a menace to society, and more especially if he be a spy that threatens the safety of yourself and comrades. There is also in this branch of intelligence service an appeal to the clash of wits that holds fascination for the keen mind. The German spy system is not more clever than our own, but has been more carefully organized and much longer in operation. He spies also on friend and neutral, while we only use this back-door method of gleaning information from an enemy. The word, too, has associations that are ugly, and I fancy that our spies do not boast of their service, but spy-hunting is a service that has no taint, and there is much satisfaction both to the conscience and intellect in routing out the underground worker who, for "filthy lucre," would sell the blood of his fellow man. The traitor and the spy have in all ages been rightly considered as foul beings who poison the air and whose touch contaminates. In Germany alone is the spy given honor which is fitting in a country which has substituted _Expediency_ for _Honor_ and _Plausibility_ for _Truth_, on whose throne is a maniac, and where _Conscience_ has been unseated by _Pride_, and _Reason_ displaced by _Method_. Germany's espionage of her neighbors has been in existence so long, and so much time and money have been expended on it that we must prepare for its reassertion after the war even in countries where it has been for a time suppressed. Its hands have been cut off, but the plotting brain and the murderous heart of the system still persist and will be used after the war to rehabilitate the trade of Germany under many disguises, and will also seek, through appeal to our pity for a fallen nation, to lull us into slumber, until the claws and fangs of militarism have grown again. We are so new in the game that our methods in spy-hunting are clumsy, and we frequently give warning to the brains of the system to seek cover when we strike at its puppets. By arresting the agents of the German master spy we cut off his activity for a time but allow him to spread his ramifications in other directions, and the first knowledge we have that he has sprung to life again is by the destruction of property and loss of life that ensue. It would sometimes pay us to give these agents more and more rope, keeping them under observation until we can strike at the centre and heart of all this plotting. When we have enough evidence against one of these agents for a death penalty we should allow him to purchase his life by betraying his master, and as these agents only serve for hire and know not what loyalty is, they are always ready to turn king's evidence if the price offered be high enough. Of course, they should not be given their liberty again, but segregated like the carrier of a contagious disease.
