For one brief instant Schwartzmann's free hand was raised protectingly to his face so contorted with rage; for one brief instant, below that big fist, there showed the contour of a jaw; and, with every ounce of weight that Chet could put into the swing, he came up from under in that same instant with a smashing left that connected with the exposed jaw.
The hand that gripped his gun-hand did not let go completely, but Chet felt the steel-hard rigidity of that arm relax, and abruptly he knew that he could beat this man down if he once got clear. He didn't need the gun; he needed only to get both hands free. And, despite the arm that clung and swung with his, he managed to wrench himself into a sideways throw of his whole body at the instant he unclosed his hand. The slim barrel of the detonite pistol described a flashing arc through the clear air and clattered along the lava underneath a big shining surface of metal.
And then, in a breath-taking flash of understanding, Chet knew.
He knew he was beside the ship: he saw the closed port and the self-retracting lever that would open it, and he saw it through clear air where no taint of the green gas was apparent.
He was certain that he had been fighting for an interminable time, yet before him the air was clear. It was impossible, but true; and he threw the half-stunned body of Schwartzmann from him. Then, instead of following it with punishing blows, he sprang toward the port.
With one hand on the lever, he turned to dart a glance toward the column of flame. It was gone! And in its place came green, billowing gas that was coughed and spewed into the air to be caught up in the steady breeze that blew directly from the vent.
Beside him, his antagonist, prone on the lava floor, dragged himself beneath the ship to reach for the gun. Chet paid no heed; his every thought—his whole being, it seemed—was focused upon the lever that turned so slowly, that let fall, at last, a lock whose releasing mechanism clanged loudly through the metal wall.
The outer port, a thin door that served only to streamline the opening, swung open under Chet's hand. And, while he held his breath till his pumping heart set his whole body to pulsing, he drew himself into the ship as the green cloud wrapped thickly about. But first he bent to grasp the knotted vines and leathery leaves that enclosed a bulky package.
