The peoples of all nations had celebrated—victors and vanquished alike—for they were tired of war. At least they thought that they were tired of war; but were they? What else did they know? Only the oldest of men could recall even a semblance of world peace, the others knew nothing but war. Men had been born and lived their lives and died with their grandchildren clustered about them—all with the alarms of war ringing constantly in their ears. Perchance the little area of their activities was never actually encroached upon by the iron-shod hoof of battle; but always somewhere war endured, now receding like the salt tide only to return again; until there arose that great tidal wave of human emotion in 1959 that swept the entire world for eight bloody years, and receding, left peace upon a spent and devastated world. Two months had passed—two months during which the world appeared to stand still, to mark time, to hold its breath. What now? We have peace, but what shall we do with it? The leaders of thought and of action are trained for but one condition—war. The reaction brought despondency—our nerves, accustomed to the constant stimulus of excitement, cried out against the monotony of peace, and yet no one wanted war again. We did not know what we wanted. And then came the announcement that I think saved a world from madness, for it directed our minds along a new line to the contemplation of a fact far more engrossing than prosaic wars and equally as stimulating to the imagination and the nerves—intelligible communication had at last been established with Mars! Generations of wars had done their part to stimulate scientific research to the end that we might kill one another more expeditiously, that we might transport our youth more quickly to their shallow graves in alien soil, that we might transmit more secretly and with greater celerity our orders to slay our fellow men. And always, generation after generation, there had been those few who could detach their minds from the contemplation of massacre and looking forward to a happier era concentrate their talents and their energies upon the utilization of scientific achievement for the betterment of mankind and the rebuilding of civilization. Among these was that much ridiculed but devoted coterie who had clung tenaciously to the idea that communication could be established with Mars. The hope that had been growing for a hundred years had never been permitted to die, but had been transmitted from teacher to pupil with ever-growing enthusiasm, while the people scoffed as, a hundred years before, we are told, they scoffed at the experimenters with _flying machines_, as they chose to call them.
