but situations with brooks are rare. The next best 

 thing is a device which supplies water by gravity 

 from a spring or a brook higher up on the property. 

 Without such a brook one or other of the systems 

 illustrated elsewhere, will be found desirable, but 

 where the supply of water is limited a device like 

 that used in flush tanks, in which the inflow is 

 regulated by a check valve and float, will be found 

 better than the style which flows continuously. It 

 is not necessary to go into the discussion of means 

 to supply water; whether gasoline engine, hydraulic 

 ram or windmill ; the only point is to have some 

 way whereby water can be supplied without daily 

 cost of labor, time and money in carrying from 

 pump to yard. While the initial cost of installa- 

 tion may seem large, yet the amount of money 

 saved in the long run will usually more than offset 

 the cost of installation.
