“We have a network of ten observation towers in this particular area,” he informed the Scouts. “Even so all points cannot be viewed, so we find it necessary to maintain ground patrols as well.”

“Can one see Pine Cone Camp from here?” Judy inquired.

“No, the camp is one of our blind spots, unfortunately,” the ranger replied. “Rest assured, it is well protected though. Lowell Diethelm patrols that area. His Forest Service car is equipped with radio telephone. If he should observe a fire, he immediately would notify headquarters. Ground fighters would be dispatched at once.”

“Do you have many fires here during the summer?” Kathleen inquired.

“Until this year, very few. Recently, we’ve had a number of small ones, mostly along the main highway. A few though, have been of mysterious origin.”

“Deliberately set?” questioned Judy.

“We’re beginning to wonder,” the ranger answered. “Carelessness, of course, is the underlying cause of most fires. But incendiarism runs high too. Now that so many summer campers and tourists are pouring into the area, we have to be especially watchful.”

Before leaving the observation tower, the Scouts studied the big topographical map and took turns peering through the binoculars.

“Well, come again girls,” the ranger invited as they prepared to leave. “Be careful of your fires. And remember, if you do see one, report it at once. Discovery time counts for a lot.”

Leaving the observation tower, the Scouts hiked on for another mile and a half. By the time they reached the Fountain Falls trail, everyone was beginning to feel the first pangs of hunger.
