"Well, Seaton, old top, you've got to cut out this loafing on the job and get busy!"

In spite of his utmost exertions and in spite of the powerful ammonia plant, now exerting its full capacity, but sadly handicapped by the fact that its cooling-water was now boiling, Seaton saw the arenak shell continue to heat. The bright red was succeeded by orange, which slowly changed, first to yellow, then to light yellow, and finally to a dazzling white; through which, with the aid of his heavy red lenses, he could still see the enemy ships. After a time he noted that the color had gone down to yellow and he thrilled with exultation, knowing that he had so reduced the numbers of the enemy fleet that their wave-generators could no longer overcome his refrigerators. After a few minutes more of the awful carnage there remained only a small fraction of the proud fleet which, thousands strong, had invaded Kondal—a remnant that sought safety in flight. But even in flight, they still fought with all their weapons, and the streams of bombs dropped from their keel-batteries upon the country beneath marked the path of their retreat with a wide swath of destruction. Half inclined to let the few remaining vessels escape, Seaton's mind changed instantly as he saw the bombs spreading devastation upon the countryside, and not until the last of the Mardonalian vessels had been destroyed did he drop the Skylark into the area of ruins which had once been the palace grounds, beside the Kondal, which was still lying as it had fallen.

After several attempts to steady their whirling senses, the three men finally were able to walk, and, opening a door, they leaped out through the opening in the still glowing wall. Seaton's first act was to wireless the news to Dorothy, who replied that they were coming as fast as they could. The men then removed their helmets, revealing faces pale and drawn, and turned to the helpless space-car.

"There's no way of getting into this thing from the outside...." Seaton began, when he saw that the Kofedix and his party were beginning to revive. Soon Dunark opened the door and stumbled out.

"I have to thank you for more than my life this time," he said, his voice shaken by uncontrollable emotion as he grasped the hands of all three men. "Though unable to move, I was conscious and saw all that happened—you kept them so busy that they didn't have a chance to give us enough to kill us outright. You have saved the lives of millions of our nation and have saved Kondal itself from annihilation."

"Oh, it's not that bad," answered Seaton, uncomfortably. "Both nations have been invaded before."

"Yes—once when we developed the ultra-violet ray, once when Mardonale perfected the machine for producing the silent sound-wave, and again when we harnessed the heat-wave. But this would have been the most complete disaster in history. The other inventions were not so deadly as was this one, and there were terrible battles, from which the victors emerged so crippled that they could not completely exterminate the vanquished, who were able to re-establish themselves in the course of time. If it had not been for you, this would have been the end, as not a Kondalian soldier could move—any person touching iridium was helpless and would have been killed."

He ceased speaking and saluted as the Karfedix and his party rounded a heap of boulders. Dorothy and Margaret screamed in unison as they saw the haggard faces of their husbands, and saw their suits, dripping with a thick substance which they knew to be red, in spite of its purplish-black color. Seaton dodged nimbly as Dorothy sought to take him in her arms, and tore off his suit.

"Nothing but red paint to stop their light-rays," he reassured her as he lifted her clear from the ground in a soul-satisfying embrace. Out of the corner of his eye he saw the Kondalians staring in open-mouthed amazement at the Skylark. Wheeling swiftly, he laughed as he saw a gigantic ball of frost and snow! Again donning his fur suit, he shut off the refrigerators and returned to his party, where the Karfedix gave him thanks in measured terms. As he fell silent, Dunark added:

"Thanks to you, the Mardonalian forces, instead of wiping us out, are themselves destroyed, while only a handful of our vessels have been lost, since the grand fleet could not arrive until the battle was over, and since the vessels that would have thrown themselves away were saved by your orders, which I heard. Thanks to you, we are not even crippled, though our capital is destroyed and the lives of some unfortunates, who could not reach the pits in time, have probably been lost.
