"I can't be sure, but it seems to me that we came past here," he said.
"I seem to remember that big rock."

"There are lots like it," observed Jack.

"Suppose we try over to the left," spoke Mark, after they had rested
for ten minutes.

They swerved in that direction, and, after keeping on that trail for
some time, and becoming more and more convinced that it was the wrong
one, they turned to the right. That did not bring them to familiar
ground, and there was no sight of the projectile.

"Let's go straight ahead," suggested Andy, after a puzzled pause. "I
think that will be best."

"Well, which way is straight ahead?" asked Mark.

"That's so, it is hard to tell," admitted the hunter. "I wish I hadn't
lost that compass."

They wandered about for an hour longer. They could seem to make no
progress, though they covered much ground. Suddenly Jack called out:

"Say, we've been going around in a circle!"

"In a circle?" asked Mark.

"Yes," went on his chum. "Here's the very rock I sat down on a while
ago. I remember it, for I scratched my initials on it."
