"No powder mills in this part of the world," he declared. "But,
gracious! The explosion seemed big enough."

Tom Reade stepped over to Prescott, whispering in the latter's
ear:

"What if this is another chapter in the lake mystery that we struck
this afternoon?"

"That's possible," nodded Dick.

"What are you two fellows whispering about?" called Hazelton.

"We're using whispers in case there's anyone else near enough
to hear speaking voices," Prescott explained in a low tone.

That was enough to fan the curiosity of the others, who, partially
dressed, crowded about Prescott and Reade.

Leaving the lantern in the tent, Dick & Co. gathered in the darkness
in the open air.

"What do you make of it, Dick?" Dave asked.

"Just as much as you fellows do---no more," came the reply.

"If it isn't anything that carries danger to us," proposed Darrin,
"we may as well go back and to bed."
