Riders of the Whistling Pines
AUTRY COMES ROARING OUT OF THE SKIES...to save the forests from outlaw lumber ring!
While pursuing Forest Ranger Charles Carter, suspected of permitting lumber man Henry Mitchell to cut restricted timber, Gene fires at a dangerous mountain lion and seemingly kills Carter. Actually, Bill Wright, Mitchell's associate, killed Carter because the ranger had discovered tussock moth infestation; if unreported, the trees would die and have to be cut, profiting Mitchell and Wright. Gene sells his sportsman's camp and gives the money to Carter's daughter Helen. En route to Texas, he discovers the infestation and is assigned by the Forest Department to supervise aerial DDT spraying. After the first day, furious stock men blame the DDT for many animals found dead of poisoning.
