"Are Greg and Harry keeping awake?" was Prescott's first question.
"They are," nodded Darrin.
"Then they can be trusted to look after the camp," Dick continued.
"And to look after the canoe," Reade amended.
"Now, we'll explore the woods a bit," Prescott went on. "We know about where we heard the explosions, and we'll look for whatever evidence we can find."
For this purpose each explorer went by himself. Ten minutes later Dave Darrin set up a loud hello. This brought the others to him on the run.
"Give us another call," demanded Dick.
"Here!" called Dave, from the depths of the woods.
Dick went in, followed by Tom and Dan.
"I've found this much," Dave announced, holding up a scorched bit of colored paper. It was such paper as is used for the outer wrapping of fireworks.
