"Just so, the sea!"

"But scouts have been here for more than a year, one team or another.
And nobody saw anything or found any traces."

"All four of our base camps were set inland, our explorations along the
coast were mainly carried out by flitter, except for one party--the one
which found this. And there may be excellent local reasons why any
native never showed himself to us. For that matter, they may not be able
to exist on land at all, any more than we could live without artificial
aids in the sea."

"Now----?"

"Now we must make a real attempt to find them if they do exist anywhere
near here. A friendly native race could make all the difference in the
world in any struggle with the Throgs."

"Then you did have more than the dreams to back you when you argued with
Fenniston!" Shann cut in.

Thorvald's eyes were on him again. "When did you hear that, Lantee?"

To his great embarrassment, Shann found himself flushing. "I heard you,
the day you left for Headquarters," he admitted, and then added in his
own defense, "Probably half the camp did, too."

Thorvald's gathering frown flickered away. He gave a snort of laughter.
"Yes, I guess we did rather get to the bellowing point that morning. The
dreams--" he came back to the subject--"Yes, the dreams
were--are--important. We had their warning from the start. Lorry was the
First-In Scout who charted Warlock, and he is a good man. I guess I can
break secret now to tell you that his ship was equipped with a new
experimental device which recorded--well, you might call it an
"emanation"--a radiation so faint its source could not be traced. And it
registered whenever Lorry had one of those dreams. Unfortunately, the
machine was very new, very much in the untested stage, and its
performance when checked later in the lab was erratic enough so the
powers-that-be questioned all its readings. They produced a half dozen
answers to account for that tape, and Lorry only caught the recording as
long as he was on a big bay to the south.

"Then when two check flights came in later, carrying perfected machines
and getting no recordings, it was all written off as a mistake in the
first experiment. A planet such as Warlock is too big a find to throw
away when there was no proof of occupancy. And the settlement boys
rushed matters right along."

Shann recalled his own vivid dream of the skull-rock set in t
