One horsepower will pump water from a well of ordinary depth in

sufficient quantity to supply an ordinary farmhouse and all the

buildings with water for all the ordinary uses.

In determining the size of power plant required in any particular

instance the use requiring the largest amount of power must be

considered. It follows that there will then be plenty of power for the

smaller requirements. In considering a water power it should also be

borne in mind that the full theoretical amount of a water power can

never be realized, a certain portion being taken up in friction in the

waterwheel and in losses in the electric generator, transmission lines,

motors, etc. The question as to how much may be made available will be

discussed hereinafter.

Following are descriptions of some typical water-power developments in

use in this State at the present time.
