"Or some such thing as that, would explain it. I don't know. The creature is good for several Ph.D. theses just as it lies—and probably an equal number of nervous collapses when we get it out."

"I find myself strongly desirous of seeing its skull," remarked Lampert. Sulewayo glanced at him sharply.

"You, too?" asked the young paleontologist. "I was hoping I was the only one crazy enough to have thought of that." Mitsuitei smiled openly, an almost unheard-of act for him. He said nothing for a moment, but everyone saw him; and even McLaughlin understood the thought. After a sufficiently long pause, he asked a question.

"Have you uncovered enough of this creature's structure to guess at any evolutionary connection—or lack of it—with the amphibids we already know on this world?"

"I'd hate to take any oaths," replied Krendall. "The legs, which we've seen most of, are different in detail; but they at least correspond in general with what we find here. The only really significant point there would be the single shin-bone. In that it resembles Viridian land life in general—these animals don't have the separate tibia and fibula characteristic of the usual run of Earthly land vertebrates. It really proves nothing about what we're all thinking, of course."

"I am tempted to work with you gentlemen tomorrow," muttered the archaeologist.

"Why? Didn't your investigation pan out?"

"It is harder for me to say than for you, so far. To dig a pit, big enough not only to work in but to cover a useful amount of ground, in a driving rain, is quite a job even with Rob's machines—which I would never use were I not sure that there is nothing of importance above the limestone level. I have gotten down to the rock over an area three meters square, which is very good going; but I shall undoubtedly find the pit full of water tomorrow, as we have not yet improvised a really satisfactory drainage system. I cannot—or at least will not—use machines inside the crack in the limestone; so it will be some time before I get down to our mysterious green threads."

"Then it would seem that the best we can do is go on as we have," said Lampert. "The only change might be if one more man were to help at Take's dig. But I don't suppose either Hans or Ndomi would care to leave his own job at the moment, and actually there's not much more to do at the hill which can be done by anyone but Take himself. I'll continue to help him as long as it's a question of moving mud, but after that he'll have to do his own sifting. String is automatically on guard duty at the hill, so there's not much change we can make. Though I must say I haven't seen anything dangerous yet, in that jungle."

"Those animals are like crows," remarked the guide. "We used to have 'em on the farm, back on Earth. They'd be all over a freshly planted field, while no one was around. Come out yelling—they don't move; come out with a gun, and they're gone—unless you'd happened to forget to load it; then they sat and laughed at you. If you're suggesting, Doctor, that I should relax the guard duty and lend a hand with digging, I veto the idea—and not because I'm afraid of getting my hands dirty."
