Ritchie nodded. "Any more than you could, a few months ago, when you tried to commit suicide. Wouldn't you say that you were thinking like a Naturalist then?"

Harry grimaced. "I suppose so."

"Don't feel ashamed. You saw the situation clearly, just as the so-called Naturalists do. And just as the government does. Only the government can't dare admit it—hence the secrecy behind this project."

"A hush-hush government plan to stimulate further breeding? I still don't see—"

"Look at the world," Ritchie repeated. "Look at it realistically. What's the situation at present? Population close to six billion, and rising fast. There was a leveling-off period in the Sixties, and then it started to climb again. No wars, no disease to cut it down. The development of synthetic foods, the use of algae and fungi, rules out famine as a limiting factor. Increased harnessing of atomic power has done away with widespread poverty, so there's no economic deterrent to propagation. Neither church nor state dares set up a legal prohibition. So here we are, at the millennium. In place of international tension we've substituted internal tension. In place of thermonuclear explosion, we have a population explosion."

"You make it look pretty grim."

"I'm just talking about today. What happens ten years from now, when we hit a population-level of ten billion? What happens when we reach twenty billion, fifty billion, a hundred? Don't talk to me about more substitutes, more synthetics, new ways of conserving top-soil. There just isn't going to be room for everyone!"

"Then what's the answer?"

"That's what the government wants to know. Believe me, they've done a lot of searching; most of it sub rosa. And then along came this man Leffingwell, with his solution. That's just what it is, of course—an endocrinological solution, for direct injection."

"Leffingwell? The Dr. Leffingwell whose name was on that photostat? What's he got to do with all this?"
