The alternators are run in multiple so that theymust run in synchronism and the speed be that of the fastestgovernor. In practice it is impossible to set all the gover-nors for the same speed and only the one set for the highestspeed does the work. The power station which houses the generators andcovers the wheel pit is a handsome building of Queenston ^1Jicd%hv^%vleW (16;$ limestone in the Moorish style of architeeture and is alongthe side of the canal.

The iagara Power Company owns 1,072 acres of landal>out its station, and leases it to manufacturing concerns deliver them directly to any of the railroads entering theBuffalo-Niagara Falls district. The first lo use power from this plant was the Pittsburgl< eduction Company which has a contract for 3,500 h. p.ilu- current is by means of static and rotary transformersconverted to a direct current at 160 volts.

IUTTE SUBSTATION, SHOWING ELECTROLYTIC LIGHTNING ARRESTERS framed structure with concrete floorsand roof. There are installed at presentfour banks of single-phase trans-formers, rated at 3,600 kilowatts perbank and connected in delta on bothhigh and low-tension sides. Theystep the voltage down from 102,000to 2,500, at which voltage it is dis- tributed to customers. The trans-formers are installed in fireproofcompartments, entirely shut off fromthe rest of the building by brickwalls and opening only out of doors.The transformers are mounted onwheels, and can readily be run outonto a flat car, which stands on atrack running parallel with the build-

This arrange-ment furnishes a convenient methodof handling the transformers, bothat the time of installation and after-ward, in case it is necessary to makerepairs. On the gallery above the trans-former compartments are located theelectrolytic lightning arresters. Onthe gallery opposite are the 100,000-volt line switches. Possibly the mostunique feature of the electrical lay-out is the 100,000-volt bus construc-tion. For flexibility in switchingduplicate busses are provided. Thebusses themselves are made of 1^2-inch iron pipe suspended by stand-ard line insulators from the rooftrusses of the building. The threeconductors of each three-phase busare suspended one above another,each being supported by the next oneabove. The connections to the linesare also of iron pipe, making the busstructure as a whole quite rigid andwell adapted to the use of su

RHODE ISLAND POWER HOUSE—LOCKING DISCONNECTS IN SUB-CELLS OF BUS ROOM exciters, auxiliary power and lighting transformers,and local service circuits. Two sets of station auxiliarythree-phase buses are installed, one at 220 volts formotor starting, and the other at 440 volts for normaloperation. These buses are run at the rear of theauxiliary board with a horizontal sectionalizing switchfor breaking up the service in emergencies. Threesets of station power transformers are mounted in base-ment compartments, with adjacent remote-controlled,solenoid-type oil switches in the taps from the trans-former secondaries to the 440-volt and 220-volt auxil-iary buses. Feeders are run in duct carried in the wall betweenpilasters from the bus and switch room to the outgoingline connections. Electrolytic lightning arresters areprovided for the various feeder circuits in a separatesection of the basement, with choke coils and discon-necting knife switches mounted on pipe framing.
