vision foresees, because this indication of what another 

 war will mean is the best possible argument for world 

 peace. Professor Low says : 



Cities will be protected against aerial attack in many ways, 

 rays of wireless power being directed at vital parts of the 

 machines from the ground, or from other aeroplanes. Vortex 

 clouds of poison vapour will be released at a sufficient height 

 to render them innocuous to those below, but deadly to the 

 pilots of any machines that entered their zones. Protective 

 rings of radio heat will be used to crumple up invading aero- 

 planes. 



Another new weapon used to disable aircraft will be electri- 

 cally controlled rockets operated on a strong wire. This will 

 be most useful, for to-day an aeroplane striking the telephone 

 wires is often crashed to the ground. 



Poison gas will be introduced in many new and terrible 

 forms, also waves of radio heat; and the equipment of the 

 fighting men and women will need very careful attention by 

 scientific chemists to supply the necessary protection. Deadly 

 germs will also be pressed into service in every possible way to 

 harass both combatants and non-combatants. 



The use of the wireless-controlled torpedo at sea, equipped 

 with radio-sighted periscopes, will render necessary travelling 

 ' jamming ' stations, which will patrol the coast and send out 

 sufficiently powerful disturbances to paralyse all controls at a 

 distance of several miles. 



There will be great activity underground, both for protective 

 purposes and because the introductions of wireless sight and 

 light will mean that night affords no cover. Government and 

 other important centres will be underground; there will be 

 scientifically constructed shelters, comfortably equipped, elec- 

 trically heated and lighted throughout. Electrically heated 

 suits will be worn during cold weather, enabling the wearers to 

 plug themselves in at different points for shelter. Advanced 

 boring machinery will tunnel underground at high speed, for 

 constructing shelters and trenches. 



Summing up this prophecy of future war, which is
