Union and Garden Prairie, approximately 10 milesapart. The three buildings are practically alike in construc-tion and equipment except that the substation at Gilberts switches, switchboards, and the other necessary apparatus. Ineach station provision is made for the installation of an addi-tional rotary at some future time. Instead of employing the usual type of strain towerthe high-tension wires enter the substation from two 45-footpoles located opposite the front of the building. The polesare securely guyed to each other and to the ground. Insula-.

The main portion of each substation is 32x31feet in floor area and 25 feet high and there is a tower atthe rear 27x12 feet in floor area which extends 7 feet abovethe main portion of the building. The walls are of brickand rest on concrete foundations. The roots are of cinder tion is provided between the poles by means of a Brooklynstrain insulator. The wires are carried on Locke No. 606high-tension strain insulators and the poles are set with theircross-arms at an angle of 45 degrees to the line. Fromthe strain poles the wires pass to a rack on the parapet atthe front of the building and thence to another rack on thewall of the tower. The high-tension wires enter the build-
