hibitive. Fire risk is reduced to a minimum, which is of greatest 

 importance on isolated farms, where fire-fighting appliances are 

 limited, Fig. 8. With a number of motors installed for the various 

 classes of service, the operating periods can be so arranged as to 

 secure a very good load-factor, thus minimizing the cost of power. 



The power supply may be obtained from the extensive net- 

 works of high-tension transmission lines which are now being 

 erected in so many sections of the country, and which are con- 

 tinuously being extended at a very rapid rate. While this supply- 

 without doubt offers the simplest and cheapest source of power, 

 there are thousands of small streams whose wasted energy might 

 readily be transformed and applied to useful work on farms by 

 the installation of small and inexpensive water-power plants. 



The following tables show some of the more important appli- 

 cations of electric drive for farm machinery and power required.
