quote, with alarm and apprehension, unquote, the fact that six percent of those between the ages of twelve and twenty-five were schizophrenics who needed institutionalizing. And he was, quote, appalled and horrified, unquote, that five percent of the nation were homeless unemployed and that three point seven percent of those were between the ages of fourteen and thirty. He said that if this schizophrenia kept on progressing, half the world would be in rehabilitation camps. But if that occurred, the sane half would go to pot. Back to the stone age. And the schizos would die."

He licked his lips as if he were tasting the figures and found them bitter.

"I was very interested by Vespa's reply to a mother who had written him," he went on. "Her daughter ended up in a Bohas camp for schizos, and her son had left his wonderful home and brilliant future to become a bum. She wanted to know why. Vespa took six long paragraphs to give six explanations, all equally valid and all advanced by equally distinguished sociologists. He himself favored the mass hysteria theory. But if you looked at his gobbledegook closely, you could reduce it to one phrase, We don't know.

"He did say this—though you won't like it—that the schizos and the transies were just two sides of the same coin. Both were infected with the same disease, whatever it was. And the transies usually ended up as schizos anyway. It just took them longer."

Gears shifted. The floor slanted. Jack was shoved hard against the rear boards by the weight of the other men. He didn't answer until the pressure had eased and his ribs were free to work for more than mere survival.

He said, "You're way off, schizo. My hitting the road has nothing to do with those split-heads. Nothing, you understand? There's nothing foggy or dreamy about me. I wouldn't be here with you guys if I hadn't been so interested in a wasp catching a caterpillar that I never saw the Bohas sneaking up on me."

While Jack described the little tragedy, the other allowed an understanding smile to bend his lips. He seemed engrossed, however, and when Jack had finished, he said:

"That was probably an ammophila wasp. Sphex urnaria Klug. Lovely, but vicious, little she-demon. Injects the poison from her sting into the caterpillar's central nerve cord. That not only paralyzes but preserves it. The victim is always stowed away with another one in an underground burrow. The wasp attaches one of her eggs to the body of a worm. When the egg hatches, the grub eats both of the worms. They're alive, but they're completely helpless to resist while their guts are gnawed away. Beautiful idea, isn't it?

"It's a habit common to many of those little devils: Sceliphron cementarium, Eumenes coarcta, Eumenes fraterna, Bembix spinolae, Pelopoeus ..."

Jack's interest wandered. His informant was evidently one of those transies who spent long hours in the libraries. They were ready at the slightest chance to offer their encyclopaedic but often useless knowledge. Jack himself had abandoned his childhood bookwormishness. For the last three years his days and evenings had worn themselves out on the streets, passed in a parade of faces, flickered by in plate-glass windows of restaurants and department stores and business offices, while he hoped, hoped....

"Did you say you spied on the camp?" Jack interrupted the sonorous, almost chanting flow of Greek and Latin.

"Huh? Oh, yeah. For two weeks. I saw plenty of transies trucked in, but I never saw any taken out. Maybe they left in the rocket."

"Rocket?"

The youth was looking straight before him. His face was hard as bone, but his voice trembled.

"Yes. A big one. It landed and discharged about a dozen men."

"You nuts? There's been only one man-carrying rocket invented, and it lands by parachute."

"I saw it, I tell you. And I'm not so nutty I'm seeing things that aren't there. Not yet, anyway!"

"Maybe the government's got
