place," returned the patrol
leader, with a smile. "But what's happened to give you that idea, Jack?"

"Just by chance," his chum went on, "I saw something moving away up on
the side of the mountain. At first I thought it might be some sort of
animal; but as I watched I made sure it was human, either a boy or man.
And whoever he was he kept track on what we were doing down here. I
could see him crane his neck to look, lots of times."

"But you couldn't recognize him?" asked Paul.

"It was pretty far, and there's a sort of haze around us just now.
Sometimes I thought I knew him, and then I made up my mind I didn't,"
came the reply.

"Is he still there, Jack?"

"Yes, but don't look up," said his chum, quickly. "We are in too plain
sight here. I thought perhaps you might step into the tent and get our
field glasses. Then we could slip away, and take a good look on the sly.
How's that suit you?"

"All right. Meet me at the place where you saw him. Where was that,

results.

Jack pointed carefully upward.

"He's there yet, because I saw him move while I waited for you, Paul,"
he said, in an eager tone.

"I've got him," answered the scout leader, as his hands became rigid.

After a brief look he lowered the glasses.

"Well, who is it?" demanded Jack.

For answer his chum offered him the glasses; and presently Jack had his
eyes glued to the smaller end.

When he lowered them a short time later his eyes met those of his chum.
Both of them laughed, as though they had exchanged their views in that
glance.

"Ted Slavin?" said Paul.

"Just as sure as fate," went on Jack; "and much interested in our
doings. That of course means trouble for us at any time. I believe all
those fellows have come up here for is to pick quarrels with us. But Mr.
Gordon will know how to handle them when he gets here."

"Meanwhile," said Paul, seriously, "we must be on our guard against a
sudden attack. We don't want the name of o
