In the switch room, the portion which adjoins the machine roomand that which contains the four-pole high-tension switch are sep-arated by a special partition of perforated iron. Above the four- points where the high tension circuits leaves the city—one to Tar-bole and the other to Varone—a tower again brings the mains aboveground. A branch of the circuit to Varone leads to St. length of the high-tension circuit in the city is miles, thelength to Tarbole is miles, to Varone miles and the branch toSt. Giacomo miles. These branches from Riva are supported. FIG. 7.—CANDELABRA WITH ARC AND INl VMH - I \ I I , I r pole switch are the measuring transformers with safety fuses, whilebelow rheostats and carbon cut-outs are arranged. On the otherside of the aisle are the machine fuses, and on the north side of theroom are eight wire fuses. Of these eight fuses, four are con-stantly under pressure, the remainder being held in reserve, so thatin case of a burning out no interruption of service will occur. The high-tension mains to Riva do not proceed by the most directroute, as that has been utilized for state telegraph wires. The cityis reached by a circuitous route over the rough surface of the moun-tain side and along the cliffs of the Lago di Garda. The mains are?carried on triangular iron brackets whose feet are imbedded in the FIG. 8.—PENSTOCK. on wooden poles and double bell insulators. The poles are 36 feetlong and the tops are charred. The mains are fitted with homedlightning arresters. The transformers are in fir
