The use of radio in fire protection practice in Ontario commenced in 1927. Development has mainly been in the northern and western districts where telephone line construction was more costly than in the older, settled districts. From 3 sets in 1927, radio equipment has been increased to 148 sets in 1940. These are of different types according to use requirements. Simplicity of operation is essential because the operators are largely untrained, although interest on the part of tower observers and other users is increasing. Two way communication is made possible by the use of a small gasoline motor of commercial type for charging batteries. Installation in towers, methods of repairing and improving equipment, and the organization of "groups" of sets is described.
