During the war, radio transmitters were regulated, and Scouts were called to look for unauthorized units. Scouts were used as message runners, coast watchers, and were to be alert for men who had not reported for duty. Over $352 million of war bonds were sold by Scouts along with $101 million War Saving Stamps. They collected fruit pits to be processed into charcoal for gas masks and inventoried black walnut trees for use as propellers and gun stocks. The War Garden program was intended for Scouts to raise food at home, but was only moderately successful.
