And then the light from the approaching star struck them in a blinding radiance of vermilion flames. Carruthers held his breath. Some invisible force seemed to take possession of his body and that of the girl at his side. The rocky plateau, now a boiling mass of rocks, dropped from under their feet. Clear, cold air enveloped their bodies. Then with the speed of light their bodies were hurled through planetary space, up, up, up into the vast reaches of the higher ether. Darkness assailed them. The flames from the jungle fire vanished into nothingness. The electron moon paled to the size of a pin point, then went out. Carruthers had the feeling of expansion and growth. It was as if his body was taking on the size of the whole world. It seemed to last for hours, days, ages. But all the while he clung fast to the slender, quivering body of Nanette. * * * * * Mountains and hills suddenly blazed before his eyes. Straight up and down mountains. He tried to stir his sluggish mind into action. What did they mean? Where had he seen them before? And while yet his mind struggled with the problem the mountains dwindled like melting snow. The pressure around his body relaxed. A blinding glare of steady light played upon his face. Then all was quietness and peace. "Nan! Aaron!" The voice was Karl's. Dazedly they looked around. What had once been mountains were now desks and chairs. They were back again in the laboratory. Several agonizing minutes passed before either could grasp the startling change in things. The horror of the electronic disaster still filled their minds to overflowing. Carruthers recovered first. He stepped from the railed inclosure marking the spot where the atomic beam had restored them after their space flight, and guided the girl to a chair. Karl's face was drawn and white as his eyes rested on the two pitiful figures that had materialized out of the ether. "Don't ask us any questions yet," spoke Carruthers in a tired voice. "We've passed through too many horrors. What was the matter, Karl? Couldn't you get the rays to work sooner?" "Sooner?" Danzig's eyes were wide with wonder. He glanced at his watch. "It was a little difficult to control both machines all alone, but I switched off the ray from the inverse dimensional tubes and turned on the other immediately. All in all it must have taken me fifteen seconds." "Fifteen seconds," repeated Carruthers, dazedly. "It's unbelievable." He dropped wearily into a chair and rested his forehead in the palms of his hands. "How long have we been gone, Nan?" * * * * * Nanette pulled the ragged remnants of a dress around her knees and attempted a smile. "Almost four months, according to the passage of time on the electron." "Impossible!" whispered Danzig, shutting his eyes to the truth.
