TILLAGE AND FARM MACHINERY m 



are sandy and too loose need rollers to pack them 

 slightly. Every sort of harvester has been devised 

 for gathering the crop. But farmers have not been 

 content with horse power alone. They have har- 

 nessed the wind to their windmills, they have 

 hitched their plows and harvesters to great steam 

 engines (Fig. 58), and they are using the power 

 of gasoline engines to do many kinds of work about 

 the farm (Fig. 59). Even electricity may be had 

 where there is a waterfall to make it cheaply. 



Care of Machinery. It is important that the 

 farmer take good care of his machinery and tools. 

 More plows have been rusted out by the weather 

 than have been worn out by use. There are three 

 good rules for every farm. Keep all tools under a 

 good roof when they are not in use. See that all 

 machinery, wagons, and the like are kept well 



Tiu. 59. A gas engine is a great labor saver on the farm.
