The battle for the extreme southern tip of the continent was the fiercest of the entire war; and when finally the last ramparts of the enemy were stormed, there arose from this fortress a considerable fleet of planes. It had not been known that the Formians still had any of these left; but nevertheless the Cupian fliers and their bee allies were ready for them, and instantly rose into the air to meet them. And at the head of the Cupian fleet rode Myles Cabot on the back of Portheris, king of the bees. But to his surprise and horror, the enemy flew southeast, instead of north, bent on escape rather than on battle. And there was no possible escape in that direction, for the way was barred by the steam clouds which overhung the boiling seas. Probably, therefore, this squadron was due soon to execute some feint. But no, they kept straight on; and before the forces of the earthman could catch up with them, they disappeared within the clouds. Cabot’s fleet wheeled and returned, driven back by the intense heat. Thus perished—presumably—the last of the ant men, for when the Cupian army stormed the fortress from which these had flown, it was devoid of defenders. No trace of Doggo or of Prince Yuri was ever found. As to Doggo, perhaps he had been slain and his serial number had been incorrectly reported by those who had found his body. Or perhaps he had been among those who had braved the steam in a heroic attempt to cheat Cabot of his final victory, by a flight to unknown lands beyond the boiling seas. It was just as well, for Cabot’s hands were not drenched with the blood of a friend. His conscience was clear, and yet he was relieved of the embarrassing alternative of having to choose between putting to death one who had saved his life, or permitting to live a member of the proscribed race. As for Yuri, undoubtedly he, too, had been among these fliers; for never could one of his spirit brook to remain, even in hiding, in a land completely dominated by his enemy and rival, Myles Cabot. Thus passed from the continent the race of black insects which had long exercised dominion over it. Poros was safe at last. The stadium was repaired, and an appropriate celebration was held therein. The lands and other property of the Formians were distributed among the war widows and the leading heroes of the Cupian soldiery. Under the regency of Myles Cabot, Cupia prospered. Luno Castle was rebuilt. Myles and his fellow scientists perfected many devices for the welfare of the people.
