"I don't think you understand me," Micheals said. "Perhaps I'm not phrasing this very well. The leech eats energy. It can consume the strength of any energy weapon you use against it."

"What happens," O'Donnell asked, "if it keeps on eating?"

"I have no idea what its growth-limits are," Micheals said. "Its growth may be limited only by its food source."

"You mean it could continue to grow probably forever?"

"It could possibly grow as long as it had something to feed on."

"This is really a challenge," O'Donnell said. "That leech can't be totally impervious to force."

"It seems to be. I suggest you get some physicists in here. Some biologists also. Have them figure out a way of nullifying it."

The general put out his cigarette. "Professor, I cannot wait while scientists wrangle. There is an axiom of mine which I am going to tell you." He paused impressively. "Nothing is impervious to force. Muster enough force and anything will give. Anything.

"Professor," the general continued, in a friendlier tone, "you shouldn't sell short the science you represent. We have, massed under North Hill, the greatest accumulation of energy and radioactive weapons ever assembled in one spot. Do you think your leech can stand the full force of them?"

"I suppose it's possible to overload the thing," Micheals said doubtfully. He realized now why the general wanted him around. He supplied the trappings of science, without the authority to override O'Donnell.

"Come with me," General O'Donnell said cheerfully, getting up and holding back a flap of the tent. "We're going to crack that leech in half."

After a long wait, rich food started to come again, piped into one side of it. First there was only a little, and then more and more. Radiations, vibrations, explosions, solids, liquids—an amazing variety of edibles. It accepted them all. But the food was coming too slowly for the starving cells, for new cells were constantly adding their demands to the rest.

After

The ever-hungry body screamed for more food, faster!

Now that it had reached a fairly efficient size, it was fully awake. It puzzled over the energy-impressions around it, locating the
