"Watch," Horstokowski warned. "When he comes back, he's going to pretend nothing happened."

Presently, Fisher returned, walking rapidly and rubbing the muck from his hands.

Horstokowski intercepted him. "What'd you find?"

"Me?" Fisher blinked. "I didn't find anything."

"Don't kid me! You were down on your hands and knees, grubbing in the bog."

"I -- thought I saw something metal, that's all."

A vast inner excitement radiated through Horstokowski. He had been right.

"Come on!" he shouted. "What'd you find?"

"I thought it was a gas pipe," Fisher muttered. "But it was only a root. A big, wet root."

There was a tense silence.

"Search him," Portbane ordered.

Two soldiers grabbed Fisher. Silberman and Daniels quickly searched him.

They spilled out his belt pistol, knife, emergency whistle, automatic relay checker, Geiger counter, pulse tab, medical kit and identification papers. There was nothing else.

The soldiers let him go, disappointed, and Fisher sullenly collected his things.

"No, he didn't find anything," Portbane stated. "Sorry, Fisher. We have to be careful. We have to watch all the time, as long as they're out there, plotting and conspiring against us."

Silberman and Horstokowski exchanged glances, then moved quietly away.

"I think I get it," Silberman said softly.

"Sure," Horstokowski answered. "He hid something. We'll dig up that section of bog he was poking around in. I think maybe well find something interesting." He hunched his shoulders combatively. "I knew somebody was working for them, here in the camp. A spy for Terra."

Silberman started. "Terra? Is that who's attacking us?"

"Of course that's who."

There was a puzzled look on Silberman's face.

"Seemed to me we're fighting somebody else."

Horstokowski was outraged.

"For instance?"

Silberman shook his head. "I don't know. I didn't think about who so much as what to do about it. I guess I just took it for granted they were aliens."

"And what do you think those Terran monkey men are?" Horstokowski challenged.

The weekly Pattern Conference brought together the nine leaders of the camp in their reinforced underground conference chamber. Armed guards protected the entrance, which was sealed tight as soon as the last leader had been examined, checked over and finally passed.

Domgraf-Schwach, the conference chairman, sat attentively in his deep chair, one hand on the Pattern composite, the other on the switch that could instantly catapult him from the room and into a special compartment, safe from attack. Portbane was making his routine inspection of the chamber, examining each chair and desk for scanning eyes. Daniels sat with eyes fixed on his Geiger counter. Silberman was completely encased in an elaborate steel and plastic suit, configured with wiring, from which continual whirrings came.

"What in God's name is that suit of armor?" Domgraf-Schwach asked angrily. "Take it off so we can see you."

"Nuts to you," Silberman snapped, his voice muted by his intricate hull. "I'm wearing this from now on. Last night, somebody tried to jab me with bacteria-impregnated needles."

Lanoir, who was half-dozing at his place, came alive. "Bacteria-impregnated needles?" He leaped up and hurried over to Silberman. "Let me ask you if --"

"Keep away from me!" Silberman shouted. "If you come any closer, I'll electrocute you!"

"The attempt I reported last week," Lanoir panted excitedly, "when they tried to poison the water supply with metallic salts. It occurred to me their next method would be bacterial wastes, filterable virus we couldn't detect until actual outbreak of disease." From his pocket, he yanked a bottle and shook out a handful of white capsules. One after another, he popped the capsules into his mouth.

Every man in the room was protected in some fashion. Each chose whatever apparatus conformed to his individual experience. But the totality of defense-systems was integrated in the general Pattern planning. The only man who didn't seem busy with a device was Tate. He sat pale and tense, but otherwise unoccupied.

Domgraf-Schwach made a mental note -- Tate's confidence-level was unusually high. It suggested he somehow felt safe from attack.

"No talking," Domgraf-Schwach said. "Time to start."

He had been chosen as chairman by the turn of a wheel. There was no possibility of subversion under such a system. In an isolated, autonomous colony of sixty men and fifty women, such a random method was necessary.

"Daniels will read the week's Pattern composite," Domgraf-Schwach ordered.

"Why?" Portbane demanded bluntly. "We were the ones who put it together. We all know what's in it."

"For the same reason it's always read," Silberman answered. "So we'll know it wasn't tampered with."

"Just the summation!" Horstokowski said loudly. "I don't want to stay down here in this vault any longer than I have to."

"Afraid somebody'll fill up the passage?" Daniels jeered. "There are half a dozen emergency escape exits. You ought to know -- you insisted on every one of them."

"Read the summation," Lanoir demanded.

Daniels cleared his throat. "During the last seven days, there were eleven overt attacks in all. The main attack was on our new class-A bridge network, which was sabotaged and wrecked. The struts were weakened and the plastic mix that served as base material was diluted, so that when the very first convoy of trucks passed over it, the whole thing collapsed."

"We know that," Portbane said gloomily.

"Loss consisted of six lives and considerable equipment. Troops scoured the area for a whole day, but the saboteurs managed to escape. Shortly after this attack, it was discovered that the water supply was poisoned with metallic salts. The wells were therefore filled and new ones drilled. Now all our water passes through filter and analysis systems."

"I boil mine," Lanoir added feelingly.

"It's agreed by everyone that the frequency and severity of attacks have been stepped up." Daniels indicated the massive wall charts and graphs. "Without our bomb-proof screen and our constant direction network, we'd be overwhelmed tonight. The real question is -- who are our attackers?"

"Terrans," Horstokowski said.

Tate shook his head. "Terrans, hell! What would monkey men be doing out this far?"

"We're out this far, aren't we?" Lanoir retorted. "And we were Terrans once."

"Never!" Fisher shouted. "Maybe we lived on Terra, but we aren't Terrans. We're a superior mutant race."

"Then who are they?" Horstokowski insisted.

"They're other survivors from the ship," Tate said.

"How do you know?" asked Silberman. "Have you ever seen them?'

"We salvaged no lifeboats, remember? They must have blasted off in them."

"If they were isolated survivors," O'Keefe objected, "they wouldn't have the equipment and weapons and machines they're using. They're a trained, integrated force. We haven't been able to defeat them or even kill any of them in five years. That certainly shows their strength."

"We haven't tried to defeat them," Fisher said. "We've only tried to defend ourselves."

A sudden tense silence fell over the nine men.

"You mean the ship," Horstokowski said.

"It'll be up out of the bog soon," Tate replied. "And then we'll have something to show them -- something they'll remember."

"Good God!" Lanoir exclaimed, disgusted. "The ship's a wreck -- the meteor completely smashed it. What happens when we do get it up? We can't operate it unless we can completely rebuild it."

"If the monkey men could build the thing," Portbane said, "we can repair it. We have the tools and machinery."

"And we've finally located the control cabin," O'Keefe pointed out. "I see no reason why we can't raise it."
