"Well, Vidac could say that the colonists were using too much of the supplies simply because it was free. And instead of imposing rationing, he's making them pay, but that he wouldn't actually take their profit."

"Yeah," growled Astro. "And there's just enough hokum in that to make everyone back at the Academy happy."

"I'm afraid we'll have to go on with it," said Tom. "Not only this exploration of the asteroid belt, but we'll have to wait for Vidac to really tip his hand."

"From the way he operates," said Roger disgustedly, "that might be never."

Blasting farther ahead through the unexplored region of outer space, the cadets, who had seen a great many space phenomena, were awed by the thickening groups of stars around them. It was Tom who finally realized that they were getting closer to the inner ring of their galaxy and that the stars and suns they were unable to see from Earth, or other Solar Alliance planets, were some fifty to sixty billion miles closer.

Gulping a cup of tea and a few sandwiches, the three cadets continued their advance toward the uncharted, unknown dangers of the asteroid belt that lay ahead of them.

Meanwhile, back on the Polaris, Jeff Marshall walked into the observatory quietly. He stood and watched Professor Sykes adjust the prisms of his telescopes, then settle himself to an hour of observation. Jeff knew that the professor would remain there for the next two hours. He felt safe in going to the storeroom and taking out the communications unit to work on it. But just to make sure, he called out, "Will you be needing anything, sir?"

"No, I won't!" barked Sykes. "If I did, I'd ask for it!"

"Yes, sir!" said Jeff. He turned away with a slight smile on his face and left the observatory. He walked quickly through the passageways of the ship until he came to the storeroom hatch. He glanced around quickly and then stepped into the quiet chamber. Pulling the cartons away from the bench, he took out the half-completed tangle of wires, and by the light of a small flashlight, he peered into the maze, trying to figure out where Roger had left off. He had traced the connections and was about to go to work when suddenly the overhead light was switched on, bathing the storeroom in light. Jeff whirled around to see Vidac, standing in the open hatch, staring at him.

"Well, Sergeant Marshall," he said, advancing toward the enlisted spaceman, "some secret experiment, no doubt!"
