Mechanically, he counted them. Twenty. Most of them were feeding, but four of them seemed to be standing a little apart from the others, watching the forest, acting as lookouts.

_Typical herd action_, Dodeth thought.

He wished Yerdeth were here; he'd show that fool what good his ten-to-the-billionth odds were.

And yet, in another way, Dodeth had the feeling that his parabrother was right. How could the life of the World have suddenly evolved such creatures? For they looked even more impossible when seen in the flesh.

Their locomotive limbs ended in lumpy protuberances that showed no sign of toes, and they were covered all over with a dull gray hide, except for the hands at the ends of their handling limbs and the necks and the faces of their oddly-shaped heads, where the skin ranged in color from a pinkish an to a definitive brown, depending on the individual. There was no hair anywhere on their bodies except on the top and back of their heads. No, wait--there were two long tufts above each eye. They--

"Do you see what they're _eating_?" Wygor's voice whispered.

Dodeth hadn't. He'd been too busy looking at the things themselves.

But when he did notice, he made a noise like a throttled "_Geep!_"

_Hurkles!_

There were few enough of the animals--only a few small population was needed to keep the Balance, but they were important. And the swamps were drying up, and the quiggies were moving in on them, and _now_--

Dodeth made a hasty count. Twenty! By the Universal Motivator, these predators had eaten a hurkle apiece!

Overhead, the Yellow Sun, a distant dot of intensely bright light, shed its wan glow over the ghastly scene. Dodeth wished the Moon were out; its much brighter light would have shown him more detail.

But he could see well enough to count the gnawed skeletons of the little, harmless hurkles. Even the Moon, which wouldn't bring morning for another fifteen work periods yet, couldn't have made it any plainer that these beasts were deadly dangerous to the Balance.

"How often do they eat?" he asked in a strained voice.

It was Wygor's robot, Arsam, who answered. "About three times every work period. They sleep then. Their metabolic cycle seems to be timed about the same as yours, sir."

"_Gaw!_" said Dodeth. "Sixty hurkles per sleep period! Why, they'll have the whole hurkle population eaten before long! Wygor! As soon as we can get shots of all this, we're going back! There's not a moment to lose! This is the most deadly dangerous thing that has ever happened to the World!"

"Fry me, yes," Wygor said in an awed voice. "Three hurkles in one period."

"Allow me to correct you, sir," said the patrol robot. "They do not eat that many hurkles. They eat other things besides."

"Like what, for instance?" Dodeth asked in a choked voice.

The robot told him, and Dodeth groaned. "Omnivores! That's even worse!

Ardan, pa.s.s the word to the scouts to get their pictures and meet at that tree down there behind us in ten minutes. We've got to get back to the city!"

Dodeth Pell laid his palms flat on the speaker's bench and looked around at the a.s.sembled Keepers of the Balance, wise and prudence thinkers, who had spent lifetimes in ecological service and had shown their capabilities many times over.

"And that's the situation, sirs," he said, after a significant pause.

"The moving and still bathygraphs, the data sheets, and the samplings of the area all tell the same story. I do not feel that I, alone, can make the decision. Emotionally, I must admit, I am tempted to destroy all twenty of the monsters. Intellectually, I realize that we should attempt to capture at least one family group--if we can discover what const.i.tutes a family group in this species. Unfortunately, we cannot tell the s.e.xes apart by visual inspection; the s.e.x organs themselves must be hidden in the folds of that gray hide. And this is evidently not their breeding season, for we have seen no sign of s.e.xual activity.

"We have very little time, sirs, it seems to me. The damage they have already done will take years to repair, and the danger of upsetting the Balance irreparably grows exponentially greater with every pa.s.sing work period.

"Sirs, I ask your advice and your decision."

There was a murmur of approval for his presentation as he came down from the speakers bench. Then the Keepers went into their respective committee meetings so discuss the various problems of detail that had arisen out of the one great problem.

Dodeth went into an anteroom and tried to relax and get a little sleep--though he doubted he'd get any. His nerves were too much on edge.

Ardan woke him gently. "Your breakfast, sir."

Dodeth blinked and jerked his head up. "Oh. Uhum. Ardan! Have the Keepers reached any decision yet?"

"No, sir; not yet. The data are still coming in."

It was three more work periods before the Keepers called Dodeth Pell before them again. Dodeth could almost read the decision on their faces--there was both sadness and determination there.

"It was an uncomfortable decision, Dodeth Pell," said the Eldest Keeper without preliminary, "but a necessary one. We can find no place in the Ecological Balance for this species. We have already ordered a patrol column of two hundred fully-armed pesticide robots to destroy the animals. Two are to be captured alive, if possible, but, if not, the bodies will be brought to the biological laboratories for study.

Within a few hours, the species will be nearly or completely extinct.

"By the way, you may tell your a.s.sistant, Wygor, that the animal will go down in the files as _wygorex_. A unique distinction for him, in many ways, but not, I fear, a happy one."

Dodeth nodded silently. Now that the decision had been made, he felt rather bad about it. Something in him rebelled at the thought of a species becoming extinct, no matter how great the need. He wondered if it would be possible for the biologists and the geneticists to trace the evolution of the animal. He hoped so. At least they deserved that much.

Dodeth Pell delayed returning to his own city; he wanted to wait until the final results had been brought in before he returned to his duties. The delay turned out to be a little longer than he expected--much longer, in fact. The communicator in his temporary room buzzed, and when he answered, Wygor's voice came to him, a rush of excited words that didn't make any sense at all at first. And when it did make sense he didn't believe it.

"What?" he squealed. "_What?_"

"I said," Wygor repeated, "that the report has come back from the pesticide column! They've found no trace of any such animal as we've described! They're nowhere to be found, in or near the clearing!"

"I think," said Dodeth very calmly, "that I'll take a little trip over to the Brightside and take up permanent residence there. It's going to be pretty hot for me around here before long."

And he cut the connection without waiting for Wygor's answer.

The armored car jounced across the gra.s.sland at high speed. Behind it, two more cars followed, each taking care not to run exactly in the tracks of the one ahead, so that there would be as little damage as possible done to the gra.s.s.

In the lead car, Dodeth Pell watched the forest loom nearer, wondering what sort of madness he would find there this time. Beside him, the Eldest Keeper dozed gently, in the way that only the very young or the very old can doze. It was just as well; Dodeth didn't feel much like talking.

This time, as they approached the clearing, he didn't bother to tell the car to stop two miles away. If the animals were gone, there was no point in being cautious. All through the wooded area, he could see occasional members of the pesticide robots. He told the car to stop at the base of the little rise that he used before as a vantage point.

Then, without further preliminaries, he got out of the car and marched up the slope to take a look at the clearing. Overhead, the burning spark of the Yellow Sun cast its pale radiance over the landscape.

At the ridge, he stopped suddenly and ducked his head. Then he grabbed his field gla.s.ses and took a good look.

The animals had built themselves a few crude-looking shelters out of the logs, but he hardly noticed that.

There were four of the animals, in plain sight, standing guard!

The others were obviously inside the rude huts, asleep!
