“Your city—I saw very tall buildings. Of what do you build them?”

“In your tongue—glass,” said Tanub. “The engineers of the Delphinus said it was impossible. As you saw—they are wrong.”

“A glass-blowing culture,” hissed Stetson. “That’d explain a lot of things.”

Slowly, the disguised sled crept through the jungle. Once, a scout swooped down into the headlights, waved. Orne stopped on Tanub’s order, and they waited almost ten minutes before proceeding.

“Wild ones?” asked Orne.

“Perhaps,” said Tanub.

A glowing of many lights grew visible through the giant tree trunks. It grew brighter as the sled crept through the last of the jungle, emerged in cleared land at the edge of the city.

Orne stared upward in awe. The city fluted and spiraled into the moonlit sky. It was a fragile appearing lacery of bridges, winking dots of light. The bridges wove back and forth from building to building until the entire visible network appeared one gigantic dew-glittering web.

“All that with glass,” murmured Orne.

“What’s happening?” hissed Stetson.

Orne touched his throat contact. “We’re just into the city clearing, proceeding toward the nearest building.”

“This is far enough,” said Tanub.

Orne stopped the sled. In the moonlight, he could see armed Gienahns all around. The buttressed pedestal of one of the buildings loomed directly ahead. It looked taller than had the scout cruiser in its jungle landing circle.

Tanub leaned close to Orne’s shoulder. “We have not deceived you, have we, Orne?”

“Huh? What do you mean?”

“You have recognized that we are not mutated members of your race.”

Orne swallowed. Into his ears came Stetson’s voice: “Better admit it.”

“That’s true,” said Orne.

“I like you, Orne,” said Tanub. “You shall be one of my slaves. You will teach me many things.”

“How did you capture the Delphinus?” asked Orne.

“You know that, too?”

“You have one of their rifles,” said Orne.

“Your race is no match for us, Orne ... in cunning, in strength, in the prowess of the mind. Your ship landed to repair its tubes. Very inferior ceramics in those tubes.”

Orne turned, looked at Tanub in the dim glow of the cab light. “Have you heard about the I-A, Tanub?”

“I-A? What is that?” There was a wary tenseness in the Gienahn’s figure. His mouth opened to reveal the long canines.

“You took the Delphinus by treachery?” asked Orne.

“They were simple fools,” said Tanub. “We are smaller, thus they thought us weaker.” The Mark XX’s muzzle came around to center on Orne’s stomach. “You have not answered my question. What is the I-A?”

“I am of the I-A,” said Orne. “Where’ve you hidden the Delphinus?”

“In the place that suits us best,” said Tanub. “In all our history there has never been a better place.”

“What do you plan to do with it?” asked Orne.

“Within a year we will have a copy with our own improvements. After that—”

“You intend to start a war?” asked Orne.

“In the jungle the strong slay the weak until only the strong remain,” said Tanub.

“And then the strong prey upon each other?” asked Orne.

“That is a quibble for women,” said Tanub.

“It’s too bad you feel that way,” said Orne. “When two cultures meet like this they tend to help each other. What have you done with the crew of the Delphinus?”

“They are slaves,” said Tanub. “Those who still live. Some resisted. Others objected to teaching us what we want to know.” He waved the gun muzzle. “You will not be that foolish, will you, Orne?”

“No
