118 FOR BETTER CROPS 



and there are -generally about six washers full. This means 

 that the machine is run about 30 minutes for a washing-, and 

 takes about .0478 part of a gallon of gasoline. This is not the 

 amount which is generally used, for the washing machines are 

 run about twice as long when they are motor driven as when 

 hand driven, and get the clothes correspondingly cleaner. 



In short, the following table shows about the amount of 

 gasoline required when using a 3-horse power gasoline engine 

 for the work about the farm. Some of the figures are from 

 actual tests and some are computations : 



One gallon of gasoline will pump 



2,454 gallons of water from well 43 feet deep. 



1,720 gallons of water from well 159 feet deep 



Will shell !^-. ■ 



264 bushels of corn. 



Will grind 



48.6 bushels of corn. 



Will separate the milk from 



300 cows. 



Will do about 



20 weekly washings without wringing. 



Will grind about 



20 sickles and 



If harvester is pulled by horses, will cut about 



4 acres of grain. 



The limit of usefulness of a gasoline engine on a farm depends 

 upon the ingenuity of the farmer. Besides the subjects men- 

 tioned, it should be made to cut the ice, put the ice in the ice 

 house, the hay in the barn, the corn in the crib, cut the alfalfa, 

 the ensilage, do the threshing, sharpen the plows and the disks, 

 sweep the floors of the house, saw the wood, light the buildings, 

 and do many other kinds of work. 



Size of Engine — What size of engine to purchase depends 

 entirely upon the farm and farmer. On the whole, it seems 

 that most farmers are purchasing too small an engine, and over- 

 looking the medium sizes. A good 4 or 5-horse power engine will 

 do anything on the farm, except thresh or fill the silo, and do 

 it as economically as a large engine which would require a 

 large force to keep it supplied with work. This same engine 

 will do all the small work about the farm, and requires only a 

 trifle more gasoline for the work than a 1 or 2-horse power 

 engine. 



With modern machines and a good gasoline engine a farmer 

 should use his mental ability in such a way that he and his 

 farm hand can do all his work, and then thereby drop the old 

 time shelling bee and threshing day. By stacking the grain
