On August 6, 1945, an American aircraft droopped a bomb on the Japanese town of Hiroshima(广岛). The bomb exploded 1,000 ft.above the ground. Within the fraction of a second, the bomb changed from a metal cylinder into an immense mass of expanding gas, millions of degrees hot. The air itself around the point of explosion began to burn. A shower of penetrating invisible rays attacked every living or dead thing in the town. The followed a shock-wave which shattered the buildings and a tremendous blast of hot air whirled the debris of stone, concrete, metal, and wood over the ground. the explosion kiiled at least 140,000 people and left tens of thousands of others maimed of disfigured for life.
Three days later, yet another bomb of the same kind gave the town of Nagasaki（长崎）the same fatal blow. It killed an estimated 54,000 people and made one and half square miles of the city an ecpanse of reddish rubble. Within the stricken area, not a single soul remained alive, and the city center looked as if it had been razed by a monster steam-roller.
