station capacity. This figure may also be used in estimating the<br />

school house load.<br />

The street -lighting load can be definitely determined<br />

be studying the conditions in the town. Reference to Figure 1 will<br />

show the plat <strong>of</strong> the town together with the location <strong>of</strong> the street<br />

lights as indicated by the circles drawn in at the street intersections.<br />

The size <strong>of</strong> the units is a question <strong>of</strong> importance which must be decided<br />

early in the study <strong>of</strong> the conditions. Small towns, prior to the install-<br />

ation <strong>of</strong> the Electric Light Plant - are generally lighted by ascetelene,<br />

gasoline, oil and sometimes gas. As a rule, these systems get run down<br />

and are valueless, and very frequently it is the poor street illumination<br />

that call the attention to the necessity for electric light, under these<br />

conditions street illumination, ndiich would be considered abominable in<br />

a city, is welcomed as a great improvement in the Village. It is prac-<br />

tically xinnecessary to endeavor to brightly ill^lminate the streets. All<br />

that is desired is that there shall be sources <strong>of</strong> light at intervals<br />

not too far apart so that it will be possible to discern objects which<br />

come between the source <strong>of</strong> light and a person stationed midway between<br />

two li^ts. If enough light is thrown down the street to make it possible<br />

to see the curb-line at any point, then the end has been met, and usually<br />

a great improvement has been made over the old system. 60 watt, 100 watt<br />

and 150 watt tungsten lamps, spaced 250 to 300 feet apart, generally<br />

meet the conditions satisfactorily.<br />

At Norvralk, it was decided that four 100 watt lamps with<br />

suitable reflectors should be placed in the business districts on the four<br />

most ijnportant comers, and twenty two - sixty watt lamps scattered throxi^<br />
