A thin disk of brass 2/4 in. in diam-eter is attached to each wire midway between the glass plates, andthus prevent, the direct access of rain 01 snow through the openings.Standard straight line insulators are used for supporting the barewires inside of the building. A similarly built and equipped house is located at Dunton wherethe branch transmission line running eastward from Woodhavenis changed from conduit to overhead construction. At the drawbridge channels in Jamaica Bay, three houses arcprovided to shelter similar apparatus. These each consist of a steelframework covered with expanded metal and concrete side wallsand a corrugated copper roof. These houses rest upon pile founda-tions. The method of entrance of wires is similar to that used inthe house at Dutchkills St. and the strains of the overhead line aretaken by a separate anchorage composed of four poles braced to- 7/£-

Overhead Line Construction. There are two general divisions of the overhead construction, thetrunk line between Dutchkills St. and Woodhaven Junction, and thebranch lines between the latter point and the other outlying sub-,stations. The trunk line is built with steel poles. The branch linebetween Dunton and Rockaway Junction, through which the sub-station at the latter point and two portable sub-stations are fed. andupon which pole line the circuits to stations not yet constructed mayeventually run, is therefore also built with steel poles From Rock-away Junction, the branch pole line to the separate outlying sub-stations are built with wooden poles. Because of the rather excep-tional height at which the cables have to be carried to clear otherwires the poles are of steel from Woodhaven Junction to the s
