"Oh, what does all that matter now?" Jrann-Pttt said sullenly. "We're all going to a Sirian zoo, anyway."

"Correctly," approved the monster-bat. "Finest zoo. Clean. Commodious cages. Reasonable visiting hours. Very nice."

Mrs. Bernardi began to cry.

"Now," the vine comforted her, "a zoo's not so bad. After all, most of us spend our lives in cages of one kind or another, and without the basic security a zoo affords—"

"But we don't know we're in cages," Mrs. Bernardi sobbed. "That's the important thing."

Professor Bernardi looked at the vine. "But why are you—" he began, then halted. "Perhaps I don't want an answer," he said. There was no hope at all left in him, now that there was no doubt.

"You are wise," the vine agreed quietly. Algol arose from Mr. Bernardi's lap and rubbed against its thick pale green stem. He knew. The mosquito-bat looked at both of them restlessly.

The yellow haze had deepened to old gold. Now it was beginning to turn brown.

"It's twilight," Miss Anspacher observed. "Soon it will be dark."

"Perhaps we'll sail right past his ship in the night," Mortland suggested hopefully.
