 At a point on the St. Maurice River, some eighty-four miles to the north east of Montreal. are located the beau tiful cascades to which the Indians seeing in them a resemblance to the glitterins bead and quill work of the people, have given the name of shaw inigan."
 The total descent of the water is 1AO feet, and the site forms one of those ideal spots for hydraulic development, of which nature has made such abundant provision in North America
 As If to render the task an inviting one to the locating engineer, nature has provided in the river just above the cascades a broad bay or upper lake, and just below the cascades, which turn through an angle Of about % degrees, there Is e second or lower lake.
 The bend in the river brings the up- per and lower water levels within a short distance of each other, thus in- viting the location of a power house at the bottom of the slope. From the south end of the upper lake or forebay, @ canal twenty feet deep and 1000 feet long leads to a point where the ground begins to fall through a vertical height of 140 feet in a horizontal distance of 500 feet. Here the canal is closed by concrete walls, which is pierced by six outlets for as many penstocks' each nine feet in diameter
 At present three penstocks are in position, carrying water to as many turbine wheels in the power house oh the shore of the lower lake. Each penstock supplies a S,000-horse-power horizontal shaft turbine, dtreet-con- neeted to a generator.
 At the present time the capacity of the station Is being enlarged by the addition of a fourth turbine, which is now being installed. This turbine is the largest which has ever been con structed.
 It has capacity of 1e,5Oo horse- power, and It's huge dimensions are we'll shown by the photograph.
 The water enters the turbine through the intake. 10 feet in diameter, at the bottom of the turbine. It flows around and fills the outer special tube, and then passes in radially through an annuIar gate. and through the wheel. and. diverging, fnaliy dis charges right and left through two large draft bends. one on either side, of which one is shown in the photo Graph. Tn tnese DSuuS are SltuabSu the bearings for the shaft, one of which is clearly visible in the view shown.
 The dimensions of this vast machine are as impressive as the photograph. It is 30 feet from base to top. 22 feet wide over all and 27 feet from center to center of the two shaft bearings. It's total weight Is 964O00 pounds. The runner or wheel, which is the rotating part of the turbine. Is of bronze, and weighs five tons. The quantity of water used when thes tur- bine Is operating under full load is enormous no less than 100000 gallons passing through per minute. Just what this figure amounts to will be understood when we state that 1t represents river 100 feet wide, feet de9p. and flowing at the rate of l 60 feet per minute.
 The present output of power from l the Ehawlnigan station is 22.50o horse4 1 power, and ef this about 10000 hoFss- power is transnltted ss miles over long distance lines to the city of Mou- trsal where 1t ls uted for strest rail-
