"Towahg was the last one I instructed," Walt was saying; and Chet knew
from the deep lines in his face that his attempt at casual talk was for
Diane's benefit; "I wonder how long Towahg remembered. He was a grateful
little animal."

"Towahg?" queried Kreiss. "Who is Towahg?"

"Ape-man," Harkness told him. "Friendly little rascal; he helped us out
when we were here before. He saved Diane's life, no question about that.
I showed him the use of the bow; jumped him ahead a hundred generations
in the art of self-defense."

"And offense!" was Kreiss' comment. "There are certain drawbacks to
arming a potential enemy."

"Oh, Towahg is all right," Harkness reassured the scientist, "although
he may have taught the trick to others of the tribe who are not so
friendly."

"Where are they? In what direction do they live?" Kreiss continued.

"Want to make a social call?" Chet inquired. "You needn't mind those
little formalities up here, Doctor."

But in the mental makeup of Herr Doktor Kreiss had been included no
trace of humor; he took Chet's remark at face value. And he answered in
words that echoed Chet's real thoughts and that took the smile from his
lips.

"But, no," said Herr Kreiss; "it is the contrary that I desire. Here we
are; here we stay for the rest of our lives. I would wish those years to
be undisturbed. I have no wish to quarrel with what primitive
inhabitants this globe may hold. There is much to study, to learn. I
shall pass the years so.

"And now," he questioned, "where is it that we go? Where shall be our
home?"

Chet, too, looked inquiringly at Harkness. "You saw more of this country
than I did," he reminded him; "what would you suggest?"

And, at sight of the serious, troubled eyes of Diane Delacouer, he
added:

"We want a site for a high-grade subdivision, you understand. Something
good, something exclusive, where we can keep out the less desirable
element. Dianeville must appeal to the people who rate socially."

At the puzzled look on the scientist's face, Chet caught Diane's glance
of unspoken amusement, and knew that his ruse had succeeded: he must not
let Diane get too serious. Harkness answered slowly:

"I saw a valley; I think I can find it again. When Towahg guided me back
to the ship, when we were here before, I saw the valley beyond the third
range of hills. We go up Fire Valley; follow the stream that comes in
from the
