Roger worked with the supervisor of the assembly groups, ordering supplies and machinery as they were needed from the wrecking crews and seeing that they were sent to the right place at the right time. One of his first jobs was the assembling of materials for the construction of the Administration Building of the colony. Less than five days after the foundation had been dug, the last gleaming sheets of Titan crystal were welded together and the building towered over the plain, a glistening monument to man's first flight to the stars.

Tom had been assigned to work closely with Vidac, who was responsible for all the construction on Roald. The young cadet welcomed the chance to observe the man in action, and time after time he found contradictions in the character of the lieutenant governor. Vidac's attitude and behavior in his drive to build the colony were completely different from his actions on the long space flight. He was a man of firmness and immediate decision. Shooting from one project to another in a jet boat, he would listen to the supervisors' complaints, make a snap decision, and then head for another project. Once Tad Winters and Ed Bush, who had taken over Astro's jet barge, had hesitated when trying to transfer a four-hundred-ton lift. A bank of atomic motors from Fleet Ship Number Twelve was to be installed in the main power plant for the colony. The motors were in a position where it was impossible to use more than one of the booms for the lift. Bush and Winters tried futilely to maneuver the jet barge into position where they could use two booms, and when Vidac arrived he promptly took charge. Using Tom as signalman, Vidac stood at the controls of the giant derrick, and after testing the strain on the five-inch cables, he yelled down to the cadet:

"Think they'll hold, Corbett?"

Tom looked at the derrick, the motors, and the boom Astro had constructed. Finally he nodded his head. If anyone else had built the jet barge, Tom would have said No, but he knew when the Venusian built something it was built solidly.

Stepping back out of range, Tom watched Vidac slowly apply power to the rockets on the jet barge. Slowly, inch by inch, the boom began to bend under the load. Vidac continued to apply power. The boom bent even more and still the motors would not lift free of the ground. The rocket exhausts on the jet barge glowed fiery red under the sustained surge of power. All over the colony, men stopped work to see if the jet barge would handle the outsized lift.

Vidac sat at the controls calmly and watched Tom. The curly-haired cadet continued to wave his hand to lift the motors. The boom continued to bend, and just as Tom thought it must snap, the motors lifted free and Vidac swung them around to the table top of the barge. He climbed down and walked over to Bush and Winters.

"Next time you're afraid to try something and waste valuable time," he barked, "you'll pay for it!"

He turned to Tom. "Let's go, Corbett," he said casually.

Day after day the work continued and finally, at the end of three weeks, the dry barren plain had been transformed into a small city. Towering above the city, the Administration Building glistened in the light of their new sun, Wolf 359, and streets named after the colonists radiated from it in all directions, like the spokes of a giant wheel.
