of the models shows the interior of the power houses. In every feature. even to the most minute detail. the models pic- ture these great. power cations most ac- curate1y. The preseI' station. 1t ia shown. is to have a neg gable added to the rear end to complet it's proportions. Almost in frontfof this first power housa is seen a small building to be built over the shaft that was, sunk into the tunnel heading at the time of the recent exten- sion of the tunnel around to wheel pit No 2. Tn future winters ice will be 1oated from the inlet canal to this head house, where. it will be allowed to drop into the tunnel. through which 1t will pass to the lower river Although wheel pit No. has not yet been completed. the Pan-Amertcan model shows how power house No. will look when it is erected over this second great pit. Near 1y all of the excavation of the pit has been comrhered, the depth attained being nearly that required, which is approxi- mately, 1S0 feet Thus from this model one gets advance information in regard to the plans of the Niagara Falls Power Company. This second power house is to have an output capacity of 55,000 horsepower, as compared with 50,000 horsepower of the present station. The length of the new station will be about 560 feet. of which, approximately 320 feet will be erected for the installation first to be placed This installation will be for 30,0o0 horsepower, the units for the balance of the output capacity of the station to be installed as demand makes necessary. In width the new power house will be about 70 feet. The model also shows that the company have adopted a covered forebay in con- nection with the new power house, and it intimates that the forebay of the pres ent station may also be covered in time. The structure that covers the forebay of power house No. will be about 40 feet wide, and 1t will serve to shelter the racks and the men working about them in winter time, and in other ways be an aid to keeping the racks free from the annoyance of Ice.
 While the two great power stations will be located on opposite side of the inlet canal, which flows between them, 1t should not be overlooked that the two wheel pits will be connected by a tun- mel having an approximate length of BIO feet and which will start from the tur- bine deck in each pit. the depth being about 13O feet below the surface. This connecting tunnel will be for the accom- modation of the company's employees in passing from one pit to the other, thus avoiding the necessity of ascending to the surface to pass from pit to pit. In size this connecting tunnel will be about 6xS feet and lined with brick.
 The second model which has to do with this wonderful development at Ni- agara Falls shows the power house with the office front cut off, thus allowing visitors in inspecting it to look right Into the dynamo room. The penstocks. the turbines, the shafts. the elevator all are there. One of the turbines will be in operation, affording the exposition vis- itors an unusual opportunity of learning exactly how power is developed at the falls The location of the models In the Electricity Building is well toward the west end. Right opposite them is the Niagara transformer plant, where the {. voltage of the transmitted electric en- ergy of Niagara is reduced from 11,OOo to 1S00 volts.
