We had settled back in our comfortable armchairs, and Professor Dringenbaum of Switzerland was just delivering the first numeral of his report, when all at once the hollow rumble of an explosion shook the building and made the windows rattle. The optimists among us passed this off as a simple earthquake, but I was inclined to think that the group of demonstrators outside that had been picketing the hotel since morning was now resorting to incendiary tactics. Though the following blast and concussion, much more powerful, changed my mind; now I could hear the familiar staccato of machine-gun fire in the streets. No, there was no longer any doubt: Costa Rica had entered into the stage of open hostilities. Our reporters were the first to disappear; at the sound of shooting they jumped to their feet and rushed out the door, eager to cover this new assignment. But Professor Dringenbaum went on with his lecture, which was fairly pessimistic in tone, for it maintained that the next phase of our civilization would be cannibalism. He cited several well-known American theoreticians, who had calculated that, if things on Earth continued at their present rate, in four hundred years humanity would represent a living sphere of bodies with a radius expanding at approximately the speed of light.
