CHAPTER 10
"The next event will be," Warrant Officer McKenny's voice boomed over the loud-speaker and echoed over the Academy stadium, "the last semifinal round of mercuryball. Polaris unit versus Arcturus unit."
As two thousand space cadets, crowded in the grandstands watching the annual academy tournament, rose to their feet and cheered lustily, Tom Corbett turned to his unit-mates Astro and Roger and called enthusiastically, "O.K., fellas. Let's go out there and show them how to play this game!"
During the two days of the tournament, Tom, Roger and Astro, competing as a unit against all the other academy units, had piled up a tremendous amount of points in all the events. But so had Unit 77-K, now known as the Capella unit. Now with the Capella unit already in the finals, the Polaris crew had to win their semifinal round against the Arcturus, in order to meet the Capella in the final round for Academy honors.
"This is going to be a cinch," boasted Astro. "I'm going to burn 'em up!"
"Save it for the field," said Tom with a smile.
"Yeah, you big Venusian ape," added Roger. "Make points instead of space gas."
Stripped to the waist, wearing shorts and soft, three-quarter-length space boots, the three boys walked onto the sun-baked field amid the rousing cheers from the stands. Across the field, the cadets of the Arcturus unit walked out to meet them, stopping beside McKenny at the mid-field line. Mike waited for the six boys to form a circle around him, while he held the mercuryball, a twelve-inch plastic sphere, filled with air and the tricky tube of mercury.
"You all know the rules," announced McKenny abruptly. "Head, shoulders, feet, knees, or any part of your body except your hands, can touch the ball. Polaris unit will defend the north goal," he said, pointing to a white chalk line fifty yards away, "Arcturus the south," and he pointed to a line equally distant in the opposite direction. "Five-minute periods, with one-minute rest between. All clear?"
