The infection spread to side streets and to other avenues, inevitably. Within an hour, a great part of middle and lower Manhattan became such an abattoir as history has no record of. The show-windows along Fifth Avenue were burst in by the push of people who were then sliced and guillotined by the cascading glass. Wooden buildings were knocked askew in places. Nobody could cope with such a situation but the mayor did his resourceful best. He ordered airplanes equipped with loud-speakers of great power to fly over the self-beleaguered city and explain what the source of the great stampede had been. Every morgue and hospital in the city and in its environs was mobilized. All bridges and tunnels were instantly cleared for the transport of the injured, as Manhattan's hospitals could not handle five per cent of the casualties. Police, using pistols with little ceremony, brought to a partial halt the epidemic of looting that occurred in the early afternoon. People were commanded to take the equivalent of air-raid shelter and to stay there. The military, acting with their usual belated but firm ineffectuality, again essayed the problem of the Word itself. Unveiling a new weapon--a rocket adapted for air-to-air combat, with a warhead of a secret explosive--the Army launched squadrons of fighters and bombers to the attack. A great cannonade over the city began near five o'clock. It was futile: the blasts disrupted edges and fringes of the letters in the sky but they mended themselves as fast as they were tattered. Army Ordinance then tried its supersecret, twenty-four-inch rockets. Careless fusing caused one of these to explode at a low level, destroying the upper stories of the Metropolitan Life Insurance Building--but subsequent accurate salvos of the tremendous weapon merely caused the letters to undulate. Shortly after six o'clock the Navy, carrying out a suggestion of Cardinal Bleatbier, tried a new tactic--the interposition of a smoke screen between the abomination and the desolated city. The idea was greeted by officers with enthusiasm. The effect of it was not. For, after some fifty Navy planes had laid a great, brown carpet underneath the Word and above the buildings, there came new and hitherto unobserved eddyings of the air and the Navy smoke was drawn into the writing on the heavens--not only fortifying and clarifying what it had been intended to obscure but also giving the letters a phosphorescent glow which became visible as soon as twilight descended.
