"In the map of nearly every country of the world three or four more red circles, a score of miles in diameter, mark the position of the dying atomic bombs, and the death areas that men have been forced to abandon around them. Within these areas perished museums, cathedrals, palaces, libraries, galleries of masterpieces, and a vast accumulation of human achievement, whose charred remains lie buried, a legacy of curious material that only future generations may hope to examine."
