 How do Formians communicate with each other?
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. 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. The next day a party of prominent scientists, accompanied by a telegrapher and two stenographers, arrived at my farm. The last of the ant-men and their ally, the renegade Cupian Prince Yuri, had presumably perished in an attempt to escape by flying through the steam-clouds which completely hem in continental Poros. Ants, six-footed, and six feet high. As he stood thus expectant, Myles realized that his present position and condition, the surrounding scenery, and the advance of the ant-men were exactly, item for item, like the opening events of his first arrival on the planet Poros. And then events began to differ from those of the past; for the three other Formians halted, and Doggo advanced alone. But Myles no longer possessed the wonderful electrical headset which he had contrived and built during his previous visit to that planet, so as to talk with Cupians and Formians, both of which races are earless and converse by means of radiations from their antennae. 11 He dreaded the paralyzing bite which Formians usually administer to their victims, and which he had twice experienced in the past; but, fortunately, it was not now forthcoming. The other three ants kept away from him as Doggo led him to the beached airplane, and soon they were scudding along beneath silver skies, northward as it later turned out.
