burg Reduction Company have built on the banks of the power 

 canal a large establishment for the manufacture of aluminum and 

 have arranged to take from the St Lawrence Power Company 

 10,000 horsepower. This power was sold upon the shaft of the 

 turbines, the Pittsburg Reduction Company putting in their own 

 generators, which are direct current and not alternating. 



At present there are seven sets or units of turbines installed, 

 each of three pairs of Victor wheels, with an output of 6000 

 horsepower per unit. Two of these units are those referred to 

 as equipped with direct-current generators for the Pittsburg 

 Reduction Company; three other units have 5000-horsepower 

 alternating current Westinghouse generators, fully installed, 

 with all connections, bus-bars, switchboards and other appur- 

 tenances; the two remaining turbines are not yet equipped with 

 electric generators. 



The village of Massena is lighted by the Pow T er Company and 

 St Lawrence water is supplied from the canal under pressure. 



Aside from the Pittsburg Reduction Company, no other indus- 

 tries are yet established. 



Power Development on Hudson River 



The Hudson Rico- Power Transmission Company. Among the 

 important developments on the Hudson river mention may be 

 made of the plant of the Hudson River Pow T er Transmission 

 Company, two miles below Mechanicville. This plant is eleven 

 miles from Troy, eighteen miles from Albany, and seventeen 

 miles from Schenectady. 



The Hudson river is here divided by an island into two channels 

 with a total width of about 1200 feet. The dam and power-house 

 were constructed in 1897 and 1898. The w-estern channel of the 

 river is used for power head and tailrace. The dam is 15 feet 

 high above the river, 8 feet thick a short distance below the crest 

 and 16 feet through the face. The original length of the spillway, 

 which was situated on the east side of the island, was 707 feet, 

 but since the original construction an additional spillway, 143 

 feet long, has been added by removing the earth and rock from 

 the river bank, one foot lower than the crest of the main dam. 

 The power-house of concrete is at the w r est end of the dam and 

 may be considered as a continuation thereof. The length of the
