Thus he easily eluded the noisy sentinels who were patrolling the lake, and soon was far into the depths of the woods. But there he stopped. To go on would undoubtedly mean traveling in a circle. It was safer where he was. So crawling into the heart of a tartan bush, he gave himself up to much needed sleep. * * * * * A crash and a roar awakened him. It was broad daylight. How long he had slept could not be known, for all hours of the day are the same on Poros, save only early morning and late evening. Again the crash and the roar. Airships must be bombing the castle, in which event all attention of the ant men was probably centered on the island in the lake, and now was the psychological time for an escape. Furthermore, by keeping the noise of the explosions always behind him, Cabot could be sure of traveling ever northward without danger of circling. So northward he pressed on, through the dense woods. But his certainty that the Formians’ attention was directed to the lake, proved to be his undoing, for he had scarcely gone half a stad, before he stumbled almost into the arms of an ant man. It is hard to say which of them was the more surprised. Cabot fired first, but missed. Then the Formian fired and missed. Then both of them retreated precipitately. Soon Myles heard his enemy radiating loudly for help. Other ants must have been much nearer to him than the lake, for the S.O.S. was promptly answered. And now there was impressed upon the earth-man one serious difference between his artificial radio-organs and the natural ones of the natives of this planet. Formians and Cupians can not only vary the capacity of their antennae—for tuning purposes—by waving them around, but also by the same method can, to a certain extent, determine the direction from which the incoming waves are arriving. But Cabot’s antennae, although looking just like those of his people, were stationary. Being artificial, they were without control-muscles at their base. He did his tuning in by means of a variable condenser and a variocoupler on his belt, and had no means for direction-finding. So now he was unable to sense from which quarter came the radiations of the approaching enemy reenforcements. Taking a chance, however, he turned sharp to the right, and struck out through the forest, in an easterly direction. Overhead the sky was beginning to darken, and there was every sign of impending rain. But Cabot did not mind this. What was a wetting compared with meeting the ant men? He heard no further calls from his enemies, and began to wonder if they had not given up the pursuit. Accordingly he turned northward again, or at least what he believed to be northward, for the bombing of Luno Castle had stopped, and there was no longer anything to guide him.
