"But—"

"In fact," said Calhoun, "I forbid it. I shall prevent it. You shan't do anything of the kind."

One of the young men, staring at Calhoun, nodded suddenly. His eyes closed. He jerked his head erect and looked bewildered. A second sank heavily into a chair. He said remotely, "Thish sfunny!" and abruptly went to sleep. The third found his knees giving way. He paid elaborate attention to them, stiffening them. But they yielded like rubber and he went slowly down to the floor. The fourth said thickly and reproachfully, "Thought y'were our frien'!"

He collapsed.

Calhoun very soberly tied them hand and foot and laid them out comfortably on the floor. Maril watched, white-faced, her hand to her throat. Murgatroyd looked agitated. He said anxiously, "Chee? Chee?"

"No," said Calhoun. "They'll wake up presently."

Maril said in a tense and desperate whisper, "You're betraying us! You're going to take us to Weald!"

"No," said Calhoun. "We'll only orbit around it. First, though, I want to get rid of those damned packed-up cultures. They're dead, by the way. I killed them with super-sonics a couple of days ago, while a fine argument was going on about distance-measurements by variable Cepheids of known period."

He put the four boxes carefully in the disposal unit. He operated it. The boxes and their contents streamed out to space in the form of metallic and other vapors. Calhoun sat at the control desk.

"I'm a Med Service man," he said detachedly. "I couldn't cooperate in the spread of plagues, anyhow, though a useful epidemic might be another matter. But the important thing right now is not keeping Weald busy with troubles to increase their hatred of Dara. It's getting some food for Dara. And driblets won't help. What's needed is thousands of tons, or tens of thousands." Then he said, "Overdrive coming, Murgatroyd! Hold fast!"
