 Who does Myles Cabot help upon returning to Poros? What does he do for them?
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. 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. So once again he made motions of writing on the palm of his left hand with the thumb and forefinger of his right; and this time the sign language produced results, for Doggo halted the procession and led Cabot into a room.
