"Of an entirely new species!" snapped Dodeth in a sudden interruption. His legs stopped their rhythmic tramp. His voice rose from its usual eight-thousand-cycle rumble to a shrill squeak. "Fry it, Wygor, if you weren't such a good field man, I'd have sacked you long ago! Your trouble is that you have a penchant for bringing me problems that you ought to be able to solve by yourself and then flipping right over on your back and holding off on some information that ought to be brought to my attention immediately!"

There wasn't much Wygor could say to that, so he didn't try. He simply waited for the raking to come, and, sure enough, it came.

Dodeth's voice lowered itself to a soft purr. "The next time you have to do anything as complicated as setting a snith-trap, you just hump right down here and ask me, and I'll tell you all about it. On the other hand, if the lower levels all suddenly become infested with shelks at the same time, why, you just take care of that little detail yourself, eh? The only other alternative is to learn to think."

Wygor winced a trifle and kept his mouth shut.

Having delivered himself of his jet of acid, Dodeth Pell looked down at the data booklet that Wygor had handed him. "Fortunately," he said, "there doesn't seem to be much to worry about. Only the Universal Motivator knows how this thing could have spawned, but it doesn't appear to be very efficient."

"No, sir, it doesn't," said Wygor, taking heart from his superior's mild tone. "The eating orifice is oddly placed, and the teeth are obviously for grinding purposes."

"I was thinking more of the method of locomotion," Dodeth said. "I believe this is a record, although I'll have to look in the files to make sure. I think that six locomotive limbs is the least I've ever heard of on an animal that size."

"I've checked the files," said Wygor. "There was a four-limbed leaf-eater recorded seven hundred years ago—four locomotive limbs, that is, and two grasping. But it was only as big as your hand."

Dodeth looked through the three pages of the booklet. There wasn't much there, really, but he knew Wygor well enough to know that all the data he had thus far was there. The only thing that rankled was that Wygor had delayed for three work periods before reporting the intrusion of the new beast, and now five of them had been spotted.

He looked at the page which showed the three bathygraphs that had been taken of the new animals from a distance. There was something odd about them, and Dodeth couldn't, for the hide of him, figure out what it was. It aroused an odd fear in him, and made him want to burrow deeper into the ground.
