Hal stooped over and picked up the revolver. He examined it carefully and
then passed it to Chester.

"Can't find anything," he said.

Chester examined the weapon with no better success.

"Well," he said at last, slowly, "there is one thing certain. You've an
enemy of some kind in the camp. It will behoove you to be careful in
the future."

"I suppose the bullet was meant for me," said Hal, "although, of course
it might have been meant for either you or Stubbs."

"Great Scott! What would anybody want to shoot Stubbs for?"

"Well, you can search me," said Hal with a shrug of his shoulders, "which
may not be very good English, but expresses my sentiments just the same."

"How about Stubbs' conspiracy? Maybe one of the conspirators has caught
Stubbs nosing about."

"By Jove! It might be that, after all," said Hal. "I wonder!"

"At all events, we shall all have to be on our guard," declared
Chester. "We don't know for which of us the bullet was meant. We'll
have to warn Stubbs."

"So we shall, and if I mistake not here he comes now."
