ad a plan.
To communicate it to his assistant was his greatest problem.

He stopped at the clearing, while Towahg urged him on across the smooth
rock. Chet shook his head and pointed away from the direction of the big
divide, and at last he made him understand. Then Towahg did what Chet
never could have done.

He followed their former trail across the stone, his head close to the
ground. Now he picked a bruised leaf: again he replaced a turned stone
whose markings showed it had been displaced, and he came back over an
area that even an ape-man would not follow as being a place where men
had gone.

From where they emerged he turned as Chet had pointed, crossed the
clearing as clumsily as the German scientist might have done, scuffed
his bare feet in a pocket of gravel, and pointed to soft earth where
Chet might walk and leave a mark of shoes. Chet grinned happily while
Towahg did his grotesque dance that indicated satisfaction, though from
afar the first cries of the pack rang in the air.

They could never have outdistanced the apes alone, Chet knew that. But
he also knew that Schwartzmann and the others would slow them up, and he
counted on the pack staying together on the trail as they traversed this
new country. He entered the jungle with Towahg where their new trail
led, and drove his tired muscles to greater speed while Towahg, always
in the lead, motioned him on.

There were stops for food at times until another night came, and Chet
threw himself down on a mat of grass and fell instantly asleep. If there
was danger abroad he neither knew nor cared. He knew only that every
muscle of his body was aching from the forced march, and that Towahg's
twitching ears were on guard.

The following day they went more slowly, stopping at times to wait for
the sounds of pursuit. They were leading the pack on a long journey;
Chet wanted to be sure they were following and had not turned back. He
left a plain mark of his boot from time to time, and knew that this mark
would be shown to Schwartzmann. With that to lead him there would be no
stopping the man: he would drive his army of blacks despite their
superstitious fears.

The short days and nights formed an endless succession to Chet. Only
once did he see a familiar place, as they passed a valley and he saw
where their ship had rested on that earlier voyage.

"This is far enough," he told Towahg, and made himself plain with sig
