A con-crete column is in series with the first gap, an electrolyticarrester in series with the second and a 5-foot fuse of No. 18copper wire in series with the third, that is to say, betweenone horn and the ground. Both horns of each gap are ofV^-inch round iron. Between the line and the first arresterthere is a hoolc type knife switch, and between the last ar-rester and the lead into the substation there is a No. 18 copperwire fuse in each conductor, placed horizontally upon thestructure especially devised for it on top of a pole. Thesefuses are inclosed in wooden tubes about five feet long,wrapped with torpedo twine. The entire arrangement of light-.

Substation Building. The substatiou building is located in the Y formed bythe railroad tracks at Avon, and together with the car shed,is adjacent to the roundhouse and division repair shop. Thebuilding is absolutely fireproof, the doors and windows beingof kalomein construction, and fitted with wire glass. Thebuilding is 39 feet S inches by 44 feet on the outside and 29feet 10 inches high from the top of the foundation to the topof the parapets. The arrangement of the 60,000-volt lightning arresters inthe yard consists of three horn gaps, arranged one behind theother, on each of the three conductors, the first gap being 4*4 uing arrester gaps, fuses and switches is mounted upon 18chestnut poles; and a suitable elevated plat
