in his
pocket, he still grasped it in his hand. The tense look on his face showed
plainly enough that he was ready to shoot right through his coat. Lew,
observing his companion's movements, followed his example.

Minute after minute the two young forest guards stood silent, listening
for the sound of axes or other customary noises that ordinarily accompany
lumbering operations. But the morning stillness was undisturbed. A puzzled
expression crept over their faces.

"Maybe that tree wasn't cut at all," whispered Lew. "Maybe it just fell
of itself."

"We'll find out," replied Charley, and cautiously they began to make their
way toward the point whence the sound had come. Sheltering themselves
behind trees, they advanced rod after rod. The stillness remained
unbroken. The stand of trees grew thinner, with more and more underbrush.
Presently they saw before them an unmistakable clearing in the forest.
Rapidly they advanced, screened by the bushes, until they stood close to
the edge of the clearing. Beyond question somebody had been cutting trees.
Over a considerable area the timber had been felled, and whoever had
felled it had cut ruthlessly. Hardly a sapling remained in all the cleared
area. On every hand trees lay prone. Some had been trimmed and cut into
pieces. Some remained exactly as they fell. Everywhere freshly cut stumps
told plainly enough what had occurred.

"Somebody's cutting timber all right enough," whispered Charley, "and it's
on state land. I wonder where they are. They certainly cut that tree we
heard fall, but I haven't heard an axe or a human voice and I don't see
any signs of lumbermen."

"Maybe they're at camp eating breakfast. It's still early, you know."

"If they are," said Charley, "then this is the very time to investigate.
We'll look around before anybody gets back."

Glancing once more about the opening to make sure that nobody was in
sight, they stepped from behind their concealing bushes and started across
the open space. But immediately they came to a dead stop. Like
rifle-shots, a succession of sharp sounds rang out, accompanied by
splashing noises. The two boys were at first alarmed, then puzzled. They
looked at each other in amazement.

"What was that?" asked Lew.

"I don't know," replied Charley. "At first I thought somebody was shooting
at us. But I didn't hear any bullets hum. And the noise didn't sound
exactly like a gun, either. It was like the noise a fellow makes when he
