"I don't understand," said Astro. "What are you going to do?"

"You'll see." The man chuckled. "You'll see. Move on!"

As they trooped out of the tunnel and down into the canyon they passed groups of men working on the many ships. The cadet recognized what they were doing at once. The unmistakable outlines of gun ports were being cut into the sides of several bulky space freighters. Elsewhere, the steady pounding of metal and grinding of machinery told the cadet that machine shops were going at full blast. He noticed a difference between the men of the patrol and the workers. Neither spoke to the other. In fact, Astro saw that it was rarely that a worker even glanced at them as they passed by.

Up ahead, Astro saw a huge building, wide and sprawling but only a few stories high. It was nearly dark now and lights began to wink on in the many windows. He guessed that he was being taken to the building and was not surprised when the leader pulled him by the arm, guiding him toward a small side door. There was a curious look about the building and the cadet couldn't figure out what it was. Glancing quickly at the wall as he passed through the door, he nearly burst out laughing. The building was made of wood! He guessed that the rebels were using materials at hand rather than importing anything from outside planets. And since Venus was largely a planet of jungles and vegetation, with few large mineral deposits, wood would be the easiest thing to use.

The inside of the building was handsomely decorated and designed. He saw walls covered with carvings, depicting old legends about the first colonists. He shook his head. "Boy," he thought, "they sure go for the Venusian stuff in a big way!"

"All right!" snapped the leader. "Stop here!"

Astro stood before a huge double door that had been polished to a brilliant luster. The cadet waited for the leader to enter, but the Nationalist stood perfectly still, eyes straight ahead. Suddenly the doors swung open, revealing a huge chamber, at least a hundred and fifty feet long. At the far end a man dressed in white with a green band across his chest sat in a beautifully carved chair. Arrayed on either side of him were fifty or more men dressed in various shades of green. The man in white lifted his hand and the patrol leader stepped forward, pushing Astro before him. They walked across the polished floor and stopped ten feet away from the man in white, the patrol leader bowing deeply. Astro glanced at the men standing at either side of the man in white. The bulge of paralo-ray pistols was plainly visible beneath their flowing robes.

The man in white lifted his hand in the salute Astro had seen before. Then the patrol leader straightened up and began to speak rapidly in the Venusian dialect. Translating easily, Astro heard him report his capture. When he concluded, the man in white looked at Astro closely and spoke three words. Astro shook his head.
