The trail was plain to see. Where the boys once had to hack their way through the thick underbrush, the monster had created a path for them. The three cadets felt better about being back in the jungle with more reliable equipment and joked about what they would do to the tyrannosaurus when they saw it again.

"I thought you were supposed to be the home-grown Venusian hick that could manage in the jungle like that fairy-tale character, Tarzan," Roger teased Astro.

"Listen, you sleepwalking space Romeo," growled Astro, "I know more about this jungle than you could learn in ten years. And I'm not foolish enough to battle with a tyranno with the odds on his side. I ran for a good reason!"

"Boy, did you run!" taunted Roger. "You were as fast as the Polaris on emergency thrust!"

"Knock off that rocket wash!" roared Connel. "The Nationalists might have security patrols in this area. They could hear you talking and blast you before you could bat an eyelash! Now keep quiet and stay alert!"

The three cadets quieted down after that, walking carefully, stepping around dead brush that might betray their presence. After working their way along the tyrannosaurus's trail for several hours, Connel called a halt, and after a quick look at his compass, motioned for them to cut away from the monster's tracks.

"We'll start working around in a circle," he said. "One day east, one south, west, and north. Then we'll move in closer to the heart of the circle, and repeat the same procedure. That should cover a lot of ground in eight days. If anything's moving around out here, besides what should be here, we'll find it. From now on, we'll have a scout. Astro, you know the jungle, you take the point, about five hundred yards ahead. If you see anything, signs of a patrol or any danger from the jungle, fall back and report. Don't try to do anything yourself. Four guns in a good position are better than one popping off by itself."

"Aye, aye, sir," said Astro. With a quick nod to Tom and Roger, he moved off through the jungle. In ten feet he was invisible. In thirty seconds his footsteps were lost in the thousands of jungle sounds around them.

"I'll take the lead now," said Connel. "Corbett, you bring up the rear. All right, move out!"

From above, in the leafy roof covering the jungle; from the side, in the thick tangle of vines; and from below, in the thorny underbrush, the eyes of living things, jungle things, followed the movements of the three spacemen, perhaps wondering if these new beasts were a threat to their lives.
