Their scientists had spent years refining by slow process the vital elements necessary to its construction. The work had started when Xenephrene came within the first faint rays of our sunlight. There was no time now to repeat that process. Unless they could remove the Control, within a few months, at most, they were doomed. * * * * * They had been truthful in telling father that there was no interplanetary vehicle ready in Garla. And Graff had left none in his Braun city. There was only the small vehicle in which Dan, Freddie and I had arrived. It was decided that father and his earth people were to return in this globe to earth at once, taking Kean with them. Kean could be taught by father how to navigate the vehicle. If on earth the Control were recovered from Graff, Kean would bring it back to Garla. They waited about a week, gathering weapons and equipment with which to fight Graff on earth. The globe was too small to take very much. They brought to earth four giant projectors of the purple ray with which to stab neutral openings in Graff's barrage; a projector of the crimson barrage itself; and the insulating equipment for some four hundred persons--black-hooded suits, masks, gloves, Infra-red goggles and ear-grids. It seemed very little, but the best that could be done. The Garlands promised to rush another vehicle to earth with other weapons. But the vehicle would be some weeks yet in construction, and the distance between the worlds was daily lengthening. It was, even now, a long voyage for father's party. They arrived--dropped into the Everglades on the evening of August 7--as I have told. Father, at the conference, would have none of the idea of surrender. And the delegates from the World Powers, heartened with the weapons now at hand, with Freddie and Dan vigorously stating that they knew how to use them--reversed their decision. The searchlight beam held steady with its defiance. Both Dan and Freddie have since told me how forcefully father spoke in Miami that night. On Xenephrene an ineffectiveness had seemed to be upon him. I had noticed it. A strange world, among strange people where he had lived and worried all those months, had beaten him down. He had seemed years older; an almost querulous, ineffectual old man. Subconsciously realizing this, Dan, Freddie and I had discarded him from all our planning. But back on earth, among his own people, his own environment, his forceful character returned. He told them, that night at the conference, about the Control. It was disturbing news. But Graff obviously had not used the Control as yet. Perhaps on earth it would not operate. There was much to do before Graff could be seriously attacked. Four Arctic A warplanes were to be equipped with the four purple ray projectors. They were to be armed with long-range Essen-Bloc guns. These guns, developed in the early fifties, just before the Great Change, were for aircraft use in war.
