The bearded man considered this and shook his head. "Over fifty. By that time they're hopeless. Leave her and bring the boy."

Miss Terry let out an agonized wail of protest and fainted across her desk. One of the men slung Paul over his shoulder and the bearded leader led the group from the room.


"Amazing," murmured Staghorn. "Absolutely amazing. One never knows what to expect."

"Pure gibberish," said Peccary, then betrayed his interest by saying, "Can you follow them?"

"I'm trying to." Staghorn worked at the geographic adjustment and finally got the screen focused on the corridor again. It was deserted. The bearded man and his companions had already departed. Staghorn touched the controls again, the screen flickered and once more the little park came into focus. But now it, too, was deserted. None of the ragged men and women were in sight, neither in the park nor on the street beyond. Staghorn twisted the focus in all directions without discovering anyone.

"That whistle we heard was obviously some kind of alarm," he said. "Everyone must be in hiding—from the Atavars, whoever they are. I strongly suspect that bearded fellow of being one."

"You might as well shut it off, Staghorn," Dr. Peccary said coldly. "It's too much nonsense for any sane man to swallow. And unless that machine can provide a full and satisfactory explanation as to why my Y Hormone will bring about the conditions depicted on that screen, I see no reason to keep the hormone off the market."

Staghorn turned from the controls to study his companion. "The only possible way that Humanac could give us the entire background of events leading up to what we've just seen would be to set the time control to the present and then leave the machine running until it arrived at this same period again. That would take a hundred years, and I'm not going to sit here that long. What's more, I'm not going to touch your Y Hormone even if you do put it on the market."

"There'll be plenty who will!"
