Direct action on fires is usually first taken by a local resident who is a commissioned volunteer fire warden. Contact with these men is maintained by 12 area fire wardens who are part of the regular forestry organization. The area wardens in turn are responsible to division wardens on the staffs of the district foresters. Three of the district foresters also have special fire-control assistants. In the state forests in Ohio, the 20 rangers in charge are responsible for fire protection within their units. Ohio operates 39 lookout towers, 4 planes, and has 2 additional private planes under contract. Equipment includes 112 2-way radios, 60 trucks, 4 tractor plows.

Fire control on national-forest lands

Nearly 12 million acres of national-forest land is protected by the U. S. Forest Service in Illinois, Indiana, and Ohio. State and private lands are so intermingled that all fire-control organizations- federal, state, and local community-work in close coordination. There are 3 national forests; headquarters are given in the Appendix on page 121. At national-forest headquarters in Bedford and Harrisburg, assistant supervisors serve as staff fire-control officers.

Forest-fire protection is part of the district ranger's administrative duties in connection with managing national-forest land. The ranger's fire-control aides are a dispatcher, a fire guard, and lookouts. The dispatcher receives reports of fires by radio or telephone at the communications and supply center at ranger headquarters. He sends men, equipment, and supplies to fires and coordinates the action. The fire guard carries on prevention work, trains lookouts and wardens, and goes to fires either as a fireman alone, or as a foreman in charge of a crew.

Rangers place a great deal of reliance for fire fighting upon their planting crews. A volunteer organization of about 10 men per district serve as fire wardens, initial action on fires in their respective neighborhoods, and authority to hire additional help. The volunteer wardens are paid when actually employed on fire duties. The U. S. Forest Service maintains 15 towers in Illinois, 7 in Indiana, and 7 in Ohio.
