spring and the house, lay the pipes and allow gravi- 

 tation to do the rest in the process of distribution. 



When the house and the spring or brook are not 

 so satisfactorily situated, it will be necessary to sup- 

 ply means of pumping the water to the right height 

 to effect proper distribution. The windmill has 

 long been depended upon for country and suburban 

 homes for the watering of stock and supplying the 

 house where the demands are not great; but, as the 

 wind cannot always be depended upon to afford suf- 

 ficient power at the time when it is most needed, 

 other forms of pumping are carefully considered. 



The various engines run respectively by gas, 

 gasoline, hot air, steam, and electric motor all have 

 their good points, according to the environments of 

 the home and the source of the water supply. The 

 hydraulic ram is one of the simplest methods of 

 solving the problem ; but, like the pressure by gravi- 

 tation, it demands special conditions, in this instance 

 it being required to have a stream of running water 

 near the house, or some means of damming up 

 spring water to supply the power, as the ram is en- 

 tirely automatic in its action. When it is possible to 

 obtain from the water of the stream the energy 

 necessary for its operation, the hydraulic ram will 



prove to be the most economical means of obtaining
