Then I shed my antennae, and stood once more, an earth-man, ready to battle for my existence against the inhabitants of Poros. We were belted together, face to face, waist touching waist. Each of us held a short sharp dagger in his left hand—Cupians being a left-handed race—while the right hand of each of us seized the left wrist of his opponent. The idea was for me to try and stab Yuri to death before he could stab me, and _vice versa_. Yuri had the advantage on the offensive, for he held his dagger in his strong hand, whereas I held mine in my weak. But conversely, I had the advantage on the defensive, for it was my strongest hand which warded him off. No spoken signal could be given, because of my receiving set being off. So Poblath held up his hand and both of us watched it. Then when he let it fall we started to wrestle. Yuri might be the most perfect physical specimen in all Cupia, but I was from a planet where the greater attraction of gravity necessitated a greater strength on the average. However, I soon perceived that these Porovian duels are not to be won by strength alone. There were tricks and feints by which one’s opponent could be tired out. And I was a mere novice, while Yuri was regarded as the most expert duelist on all Poros. We tumbled and rolled about the floor, with first his knife and then mine near its mark. At last we both struggled to our feet again and swayed back and forth for a moment. And then, gradually, Yuri’s dagger began to descend. Strain as I would, I could not stay its slow and steady progress toward my heart. A gleam of exultation filled the eye of my opponent. The point of his knife pricked my breast, and began to enter. In a few seconds it would be over and I should fall a victim to an alien race. A strange train of ideas ran through my affrighted mind: “Alien race. Japanese. Jiujitsu. The very thing! The ulnar nerve!” Suddenly shifting my grip on his wrist, I forced my thumb into the sensitive spot; and instantly his knife, about to pierce my heart, dropped instead from his nerveless fingers and clattered harmlessly to the floor. And now what was the etiquette of the situation? I turned my glance from Yuri’s eyes to those of Poblath and saw the latter frantically motioning me to kill. To kill! Nothing would give me greater pleasure. But as I returned to the task, I noted the Princess Lilla standing in the crowd, with a look of terror on her face. Her appealing eyes showed that she was speaking to me, probably urging me to spare the prince. So she cared for the scoundrel after all! In disgust, I threw my own knife into a corner, and signaled to Poblath to remove the belts. He did so, reproachfully, and then handed me my receiving set. Something prompted me to put it on in haste, and it is well that I did so, for as I snapped the ear phones in place, I heard Yuri shout: “Quick, two of you cover Cabot and the mango.”
