“Because Old Noah found a cache of dynamite somewhere near here.”
“He won’t tell us its location,” added Louise.
“If it should develop that the men are saboteurs, we might learn something which would help your brother’s case,” Penny said persuasively. “How about it, Sara?”

“Then let’s leave it here. We can watch the spot night and day.”
“And what will your parents have to say?”
Penny’s face fell. “Well, I suppose when it comes right to it, Dad will set his foot down. But at least we can watch during the day time. Then if necessary, we might report to the police.”
“Let’s leave them out of it,” Sara said feelingly. “If you girls will remain throughout the day, I’ll stand the night watch.”
“Not alone!” Louise protested.
“Why not?” Sara asked, amused. “I’ve frequently camped out along the river at night. Once I made a canoe trip the full length of the river just for the fun of it.”
