 How did Doggo feel about their plan?
The university authorities will express no opinion as to whether or not these messages come from Mars. He had driven the last ant from the face of continental Poros, and had won and wed the Princess Lilla, who had borne him a son to occupy the throne of Cupia. In conventional radioese, I repeated the sounds to the Harvard group: “Dah-dit-dah-dit dah-dah-dit-dah. 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. What lay beyond the boiling seas no man knew. Yes, there could be no mistake; an airplane was approaching. Gone was all his languor, as he seized a piece of driftwood and prepared to defend himself. 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. He even recognized one of the ant-men as old Doggo, who had befriended him on his previous visit. Could it be that all his adventures in Cupia had been naught but a dream; a recurring dream, in fact? Were his dear wife Lilla and his little son Kew merely figments of his imagination? 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. So he picked up two sticks from the beach, and held them projecting from his forehead; then threw them to the ground with a grimace of disgust and pointed to his ears. Doggo understood, and scratched with his paw in Cupian shorthand on the silver sands the message: “Myles Cabot, you are our prisoner.” 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.
