economical use under proper care is widely known 

 and appreciated. The pumping of water to the 

 height of the largest tank or reservoir is very simply 

 accomplished by use of one of these small engines. 

 It has an additional advantage in being so simple 

 in operation that it can be started and stopped in a 

 few seconds' time. This not only effects a saving 

 in the cost of the fuel but also in doing away with 

 the necessity of employing skilled attendants the 

 small boy of the home being able to stop or start it 

 at will and there is a decided point in its favor in 

 the fact that this form of engine costs nothing when 

 it is not working ; and the working time is short for 

 pumping enough water to fill a large reservoir. The 

 first cost is also slight compared with some forms 

 of power; as an engine can be installed for from 

 eighty-five to one hundred and fifty dollars which 

 will give good service for many years. Engines at 

 the low cost of eighty-five dollars under proper man- 

 agement will pump one thousand gallons an hour 

 from a well twenty-four feet or more in depth, to a 

 tank situated at least eighty feet above the well. 

 Another advantage lies in the fact that the gasoline 

 engine used for pumping water may also serve other 

 home requirements as a source of power. 



The hot-air engine is another of the dopendables 

 which will not require special conditions of location
