duit Company uses some 1,000h. p. which is transformed to a pressure of 11,000 volts andtransmitted to Buffalo. At the Falls end there are twotransformers located in the transformer house across thecanal from the power house. Each has a capacitj of 935k. w. They are 94 in. high on a base 56x64 in., and weigh25,000 lbs. each ; they are cooled by a blast of air driven upthrough the core and cells. At the Buffalo end there arethree transformers which step down the current from 10,700volts (the line loss being 300) to 370 volts. This current iscarried to two 500-h. p. rotary converters which feed therailway bus bars at 500 volts. This equipment was fur-nished by the General Electric Company. The transmission line to Buffalo was built by the NiagaraFalls Power Company at great expense. The line is 26miles long, and for 18 miles a strip of land 30 ft. wide waspurchased outright; for five miles the line is along the ErieCanal. The line was constructed by the White-CrosbyCompany of Baltimore.

SAMPLES OF LINE CONSTRUCTION—NIAGARA FALLS-BUFFALO TRANSMISSION. ^t\£d%ilw&i\%vlcW 065 Cellar poles, i8 in. at tlie Initt, S in. at the lop and from -^^to 65 ft. long were planted 75 ft. apart. These poles carrythree cables, each of 19 strands, having a total cross-sectionof 3^0,000 c. m. For the last 4,200 ft. the cables are laid invitrified tile ducts. One of the greatest ilitKculties in theconstrnction of the line was in securing insulators whichwould stand a high voltage test. By co-operation with themanufacturers great improvements were made in the insul-ators. That adopted was a double jietticoated one of porce-lain, made by the Imperial Porcelain Works of Trenton,X. J. All of the feeder cables for this line—two order for75 miles each, 150 miles of 3^0,000-c.m. cable—were fur-furnished bv the American Electrical Works of Providence,R. I. Recent tests have shown the insulation resistance of theline to be 300,000 ohms on wet days and 1,000,000 on drydays. The actual wor
