It was five years later before a sending apparatus was evolved that bade fair to transmit its waves from Earth to Mars. At first their own message was repeated—three dots and three dashes. Although the usual interval of time had not elapsed since we had received their daily signal, ours was immediately answered. Then we sent a message consisting of five dots and two dashes, alternating. Immediately they replied with five dots and two dashes and we knew beyond peradventure of a doubt that we were in communication with the Red Planet, but it required twenty-two years of unremitting effort, with the most brilliant intellects of two world concentrated upon it, to evolve and perfect an intelligent system of inter-communication between the two planets. Today, this tenth of June, 1967, there was published broadcast to the world the first message from Mars. It was dated Helium, Barsoom, and merely extended greetings to a sister world and wished us well. But it was the beginning. The Blue Room of _The Harding_ was, I presume, but typical of every other gathering place in the civilized world. Men and women were eating, drinking, laughing, singing and talking. The flier was racing through the air at an altitude of little over a thousand feet. Its engines, motivated wirelessly from power plants thousands of miles distant, drove it noiselessly and swiftly along its overnight pathway between Chicago and Paris. I had of course crossed many times, but this instance was unique because of the epoch-making occasion which the passengers were celebrating, and so I sat at the table longer than usual, watching my fellow diners, with, I imagine, a slightly indulgent smile upon my lips, since—I mention it in no spirit of egotism—it had been my high privilege to assist in the consummation of a hundred years of effort that had borne fruit that day. I looked around at my fellow diners and then back to my table companion. He was a fine looking chap, lean and bronzed—one need not have noted the Air Corps overseas service uniform, the Admiral’s stars and anchors or the wound stripes to have guessed that he was a fighting man; he looked it, every inch of him, and there were a full seventy- two inches. We talked a little—about the great victory and the message from Mars, of course, and though he often smiled I noticed an occasional shadow of sadness in his eyes and once, after a particularly mad outburst of pandemonium on the part of the celebrators, he shook his head, remarking: “Poor devils!” and then: “It is just as well—let them enjoy life while they may. I envy them their ignorance.” “What do you mean?” I asked. He flushed a little and then smiled. “Was I speaking aloud?” he asked.
