His footwork was smooth, and the giant pounded air. Again Epworth’s right found lodging in the giant’s abdomen, and he grunted a little, faintly, and advanced with fists on guard.

It was evident that he knew a little about boxing, and Epworth’s heart weakened. He had been counting on Toplinsky’s ignorance. If the man was only partially skilled his great weight, long reach, and massive power gave him the decided advantage. Yet the young American, though a little doubtful, had no intention of permitting fear to gain possession of him. Fear, he knew, would result in quick defeat.

He sprang forward like a catapult, dodged downward just as the giant met him with a terrific blow at his face, and got in two good blows before Toplinsky could regain his equilibrium. Then with deft footwork he slipped beneath the giant’s arms, battered him in the rear of his short ribs, and darted out of reach.

“Atta boy! At——”

But again Billy’s mouth was choked off.

Toplinsky did not speak. Very quietly he paused, and studied his opponent attentively. It was a menacing, cruel, determined gaze. Joan caught his facial expression and suppressed a cry of terror. She was beginning to think that Epworth was a great fighter for one so small and that he might whip this enormous beast but that if he did Toplinsky would break his promise, and be more terrifying in defeat than in victory. His cruel red face expressed this thought. She shuddered, and glanced helplessly at the colonists who were backing Toplinsky. They were grim visaged and fierce, and there was small promise of help in that mass of intent, unsympathetic faces.

Her thoughts were broken by Epworth. The American made a dash as if he intended to strike the giant in the face. Toplinsky covered and shot his hands up in front of his face. Instantly Epworth stopped his rush, and kicked his opponent with all the force of his leg and foot in the pit of the stomach. The giant doubled up with a groan, and instantly Epworth sent a mighty right hand blow to the back of his neck.

Toplinsky went down, his followers groaned, and the Americans sent up a shout of triumph.

It was short-lived. The giant in falling threw out his right and encircled Epworth’s neck. When he got to his feet with his hands around the American’s neck he gave a ferocious grin, and stuck his face, streaming with blood, against Epworth, at the same time jabbing the American with his left. Epworth retaliated with a short hand jab into the scientist’s stomach. Again the giant’s mighty left landed in the American’s face. If he could not soon break loose from the terrific embrace around the neck his face would be pounded to a jelly.

Bending his head he lifted his feet, permitting the giant to sustain his weight for a fraction of moment, and doubling up slammed both feet with all of his strength into Toplinsky’s abdomen. In order to sustain his footing the giant held him up, and then slammed his terrible left on his nose. The blood spurted out like a pump working but in regaining his equilibrium Toplinsky slightly relieved the strangle hold around the American’s neck. Taking the blow in his face, quick as thought Epworth struck back with all of his strength, landing beneath the giant’s chin. He had his mouth open at the time, and his tongue was caught between his teeth.
