 How do Formians communicate with each other?
I exclaimed, as my eye fell on the following item: SIGNALS FROM MARS FAIL TO REACH HARVARD Cambridge, Massachusetts, Wednesday. So far as it has been possible to test the direction of the source of these waves, it appears that the direction has a twenty-four hour cycle, thus indicating that the origin of these waves is some point outside the earth. The university authorities will express no opinion as to whether or not these messages come from Mars. Myles, alone of all the radio engineers of my acquaintance, was competent to surmount these difficulties, and thus enable the Cambridge savants to receive with clearness the message from another planet. 6 Twelve months ago he would have been available, for he was then quietly visiting at my farm, after five earth-years spent on the planet Venus, where, by the aid of radio, he had led the Cupians to victory over their oppressors, a human-brained race of gigantic black ants. While at my farm Cabot had rigged up a huge radio set and a matter-transmitting apparatus, with which he had (presumably) shot himself back to Poros on the night of the big October storm which had wrecked his installation. They utterly failed to comprehend the matter-transmitting apparatus, and so—after the fallen tower had been reerected and the rubbish cleared away—they had devoted their attention to the restoration of the conversational part of the set. In conventional radioese, I repeated the sounds to the Harvard group: “Dah-dit-dah-dit dah-dah-dit-dah. Dah-dit-dah-dit dah-dah-dit-dah. Dah-dit-dah-dit dah-dah-dit-dah. Dah-dit-dah-dit dit-dah dah-dit dit dit dah-dah-dah dah. Dah-dit-dah-dit dit-dah dah-dit-dit-dit dah-dah-dah dah. Dah-dit-dah-dit dit-dah dah-dit-dit-dit-dah dah-dah-dah.” “Yes,” I answered quickly, “One-X-X-B.” “One-X-X-B,” he continued the ticking “K.” Interplanetary communication was an established fact at last! But what meant more to me was that I was again in touch with my classmate Myles Standish Cabot, the radio man. The next day a party of prominent scientists, accompanied by a telegrapher and two stenographers, arrived at my farm.
