But not only are barbed wires used, but also electrically charged wires in some cases, though between the lines they will seldom be of much use for a single shell may short circuit the system and it be rendered harmless. An effective method was that of placing trip wires near the ground, and then a little beyond them bayonets with the sharp points uppermost, or pointed sticks, so that when the man tripped over the wire he would fall and impale himself on the spikes. Sometimes bombs were attached to the wires in places where it was thought likely that the enemy would attempt to cut them or come through them. As these entanglements have to be erected during the night and under the fire of the enemy it will be seen that it becomes exceedingly dangerous work. But it has to be done, and the risk must be taken for the sake of the additional security it will give to the trenches. It has been suggested that this is work to which the conscientious objectors in England--the Pacifists here--might be put. It is necessary work for the preservation of life, and is not specifically military. It is labourer's work. There is no chance of fighting out there nor of taking human life. Then it offers an excellent opportunity of winning the martyr's crown because some one is sure to turn a machine gun on you if you remain out there long enough. All of these points should appeal to Pacifists. But the greatest reason from our point of view is that it would save the lives of valuable men! The men in the trenches are further protected by men whose business it is to go out into No Man's Land and remain there hours at a time, lying in some kind of hole, and listening to be able to detect the presence of the enemy. Should the enemy make his appearance in small parties, these listening posts can usually take care of them, but when they are in large parties, the listening post men return to the trenches and give warning. The best nerves are needed by the men who go out into the open to do this work, and sooner or later every one has to take a turn at it. These listening posts are sometimes entirely disconnected from the trenches, and out beyond their own barbed wire, through which the men have to make a passage for the time being, and of course keep it secret. But sometimes they are connected with the fire trench by a shallow trench or sap which is dug out into the neutral territory whenever circumstances are favourable.
