A barrage of unintelligible words cut his protest short. Schwartzmann poured forth imprecations in an unknown tongue, then turned to the others.
"Back!" he ordered. "Bah!—such men! The danger it iss over—yess! This pilot, he will take us back safely."
He turned his attention now to the waiting Chet. "Herr Bullard, iss it not—yess?"
He launched into extended apologies—he had wanted a look at this so marvelous ship—he had spied upon it; he admitted it. But this murderous attack was none of his doing; his men had got out of hand; and then he had thought it best to take Chet, unconscious as he was and return with him where he could have care.
And Chet Bullard kept his eyes steadily upon the protesting man and said nothing, but he was thinking of a number of things. There was Walt's warning, "this Schwartzmann means mischief," and the faked message that had brought him from the hospital to get the ship from its hiding place; no, it was too much to believe. But Chet's eyes were unchanging, and he nodded shortly in agreement as the other concluded.
"You will take us back?" Schwartzmann was asking. "I will repay you well for what inconvenience we have caused. The ship, you will return it safely to the place where it was?"
And Chet, after making and discarding a score of plans, knew there was nothing else he could do. He swung the little metal ball into a sharply-banked turn. The straight ray of light from an impossibly brilliant sun struck now on a forward lookout; it shone across the shoulder of a great globe to make a white, shining crescent as of a giant moon. It was Earth; and Chet brought the bow-sights to bear on that far-off target, while again the thunderous blast was built up to drive them back along the trackless path on which they had come. But he wondered, as he pressed forward on the control, what the real plan of this man, Schwartzmann, might be....
Less than half an hour brought them to the Repelling Area, and Chet felt the upward surge as he approached it. Here, above this magnetic field where gravitation's pull was nullified, had been the air-lanes for fast liners. Empty lanes they were now; for the R. A., as the flying fraternity knew it—the Heaviside Layer of an earlier day—marked the danger line above which the mysterious serpents lay in wait. Only the speed of Chet's ship saved them; more than one of the luminous monsters was in sight as he plunged through the invisible R. A. and threw on their bow-blast strongly to check their fall.
