. Electrical world. h a concrete tunnel from the lake. Power house No. 2. the first to be built, was used during the earlyconstruction period, and is held in reserve at the present time. Powerhouse No. I is the most centrally-located and the most contains the electrical plant, the air compressors, the hydraulicpumps and several blowing engines for the Bessemer plant; in fact,all of the power plant which it has not been considered advisable toinstall in separate power houses. It contains all machinery for thegeneration of power which is to be distributed in small units overthe entire area of the works. The power house is 77 x 725 ft. in of the same type as employed for all buildings, namely, steelskeleton with brick curtain wall construction. A 25-ton electrictraveling crane built by the .\merican Engineering Company com-mands the entire floor space. It is heated by the Buffalo Forge Com-panys hot blast system.

Ingersoll-Sergeant cross-compound air compressors, eachrated at 950 cu. ft. of free air per minute at 100 pounds machinery for tilting converters, manipulators, etc., isoperated by water at a pressure of 450 pounds, three accumulatorsbeing installed in the building. There are two Snow and twoKnowles 20 x 9 x 36-in. duplex pumps and seven 29 x g/i x pumps. The boiler feed pumps for power house No. 2are also installed in the building. There are one Blake and threeKnowles 30 x 16 x 24-in. pumps. The blowing engines housed inthe-power house supply air to the converters in the Bessemer steeldepartment. There are four of these, two of these having engines 52 X 60 X 60 in., and two 50 x 54 x 60 in., made by the .Mlis-Chal-mers Company. The engines are
