This estimate is very liberal. The asaTsnption is made<br />

that every house in the village will be wired for electricity. This<br />

condition will not exist* A second assximption is made that at dinner<br />

time and throu^ the early hours <strong>of</strong> the evening, each one <strong>of</strong> the ninety<br />

residences will be burning four twenty-five watt tungsten lamps. This<br />

community is composed <strong>of</strong> farmei^ - accustomed all their lives to kerosene<br />

lamp light and most <strong>of</strong> them will probably be satisfied with one light<br />

in the dinning room, one in the kitchen, one in the sitting room and<br />

one on the porch; ^ich will all probably burn during the peak hour.<br />

Other lights in bedrooms, bar»i^,etc,, will burn at <strong>of</strong>f-peak-hours.<br />

However - a few cases <strong>of</strong> extravagance in fixtures, etc., will rapidly<br />

bring up the average - so that it is good practice in estimating the<br />

load for lighting the residences in a village <strong>of</strong> this character to use<br />

this figure <strong>of</strong> 100 watts per residence.<br />

The estimate <strong>of</strong> 150 watts central station capacity for<br />

business houses is very fair - when consideration is taken <strong>of</strong> the<br />

type <strong>of</strong> business establishment tsrpical <strong>of</strong> the town. There are but few<br />

concerns in the town which are progressive enou^ to illuminate their<br />

stores in a modern manner. In these few stores, for estimating pur-<br />

poses, the figure <strong>of</strong> one watt per square foot may be used; while in<br />

most <strong>of</strong> the stores it is safe to figure that a light will probably<br />

be used in each window with additional lights spaced ten or fifteen<br />

feet apart down the center <strong>of</strong> the store.<br />

Each church will present a separate problem, and an<br />

accurate estimate <strong>of</strong> the load which they will supply can only be made<br />

after detailed study <strong>of</strong> each has been made. However, the figure <strong>of</strong><br />

1500 watts for each churoh is close enou^ for determing the central<br />
