"Good idea," said Tom.

The three cadets climbed into the jet boat, Tom taking the pilot's seat. He pushed a release button, and a portion of the Polaris' steel hull slid back. Tom pressed another button, gripped the wheel of the small space craft, and stepped on the acceleration pedal. The little red ship shot out of the open hatch and zoomed over the giant trees.

Traveling at a slow speed, Tom made a wide arc over the forest, checking his position against that of the Polaris before losing sight of it. He pulled the tiny ship up to one thousand feet, leveled off, set the automatic pilot, and took his first close look at Tara, four and a half light years from Earth.

From above, Tara seemed to be a quagmire of reptiles, dinosaurs, and dense vegetation reaching as high as the gleaming towers of Venusport and Atom City. Huge trees that spread their branches over an area of a thousand feet soared skyward, limbs and trunks wrapped in jungle creepers. Now and then Alfie would grasp Tom or Astro by the arm and point a wavering finger at a moving animal below, then gasp and fall back white-faced into his seat. While Tom was inclined to share Alfie's reactions, Astro took it in stride, having been exposed to the dangers of wild jungles on his own Venus.

The tiny jet boat raced out across the blue-green sea that swept up in giant swells along the snow-white sandy beaches. It was a temptation to set the small craft down and enjoy the pleasure of a swim after the many days of cramped, tortured living on the Polaris. But Tom remembered Connel's orders and also had a lot of respect for some of the things he had seen swimming in the water.

"Better get back," said Tom. He flipped the audiophone switch in the jet boat and spoke into a small mike.

"Jet boat one to Polaris. Jet boat one to Polaris. Cadet Corbett to Major Connel."

There was a crackle of static and then Connel's voice, vibrant and clear, filled the small cabin.

"Corbett!" he roared. "By the craters of Luna, I couldn't contact you. Return to the Polaris on the double!"

"Is there something wrong, sir?" asked Tom, apprehensive after seeing the wildness of the jungle below him.
