The generators are direct-connected tothe water wheels and are 3-phase, 1,100 volts, 60 cycle, The generator voltage is stepped up to a line volt-age of 22,000 volts through air blast transformers, of whichthere are four banks, three transformers in each bank, witha capacity of 1,000 per bank. AH the electrical equip-ment in this plant was furnished by the Canadian GeneralElectric Company. No. 2 Plant This plant is situated at Upper Bonnington Falls, dis-tant about one mik from Xo. 1 plant. Construction work. Power HouKe No. 2—Discharge Side was commenced in July, 1905, and completed in January,1907. The power house is built in the channel on the northside of the river. About 70,000 cubic yards of solid graniterock had to be excavated for forebay, power house siteand tail race. The natural head of water is about 63 feet at low waterstage, but, during high water this head is reduced to 56 feet on account of a difference of seven feet beivsceii therise of water above and below the falls. This differenceof water level is caused by the contracted area of the chan-nel, a short distance below the falls. To overcome thisloss of head during high water the power company have<lecided, when load demands it, to remove the obstructionin the channel below the falls, thus increasing the sectionalarea to such an extent that the water level at high waterbelow the falls will be lowered about five feet. They alsowill build a dam across the river above the falls, which
