HARNESSING NIAGARA.

在今年可能Canadian side of the Niagara falls the lead in the electrical horsepower will well belong to the Dominion of Canada. There are three companies established in the lands about ths Horseshoe falls, the Canadian Niagara Power company, which will develop 110,000-horsepower; the Electrical Development company of Ontario, which will develop 125,000 horsepower, and the Ontario Power company, which will develop 186,000-horsepower—a total of 415,000-horsepower, with a prospect of further development. The Canadian Niagara Power company will soon be at work, with the greatest turbines and generators ever built. The plan adopted is the same as that of the Niagara Falls Power company, in alliance with the Canadian company, on the New York side, namely, a wheelpit and tunnel tail-race, the pit being the same on both sides. The tunnel, however, is shorter, being 2,200 feet as against 7,000 on the American side. The portal is close up by the Horseshoe falls. The tunnel is slightly the longer of the two, but, on account of its shortness, the development will be much more economical. The leading feature of this development will be the size of the unit required for it, which will be ro,ooo-horsepower, double that on the New York side, produced by a turbine and generator, which require little more space than a set developing only 5,000-horsepower. The Electrical Development company is developing power in Victoria park, has also adopted the wheelpit and tunnel method. The latter will be about 2,000 feet long, twenty-four feet wide, and twenty-six feet high, built in the form of a horseshoe, and will discharge behind the sheet of water of the Horseshoe fall. At its upper end two lateral tunnels will extend 165 feet to the ends of the wheelpit, and throughout these lateral tunnels the water from the turbines will reach the main tunnel. The Ontario Power company has built two large forebays in Victoria park, above the Dufferin islands, carefully screened so as to avoid inconvenience from ice in the winter. The gatehouse will be at the lower end of the inner forebay, whose waters will flow into the huge eighteentnch steel pipes-—the largest ever used in connection with a power development. The pipes are of steel plates riveted together, and covered outside first with concrete, then with earth, to equalize the earth pressure. One of these steel flumes is now in place. It is over 6,000 feet long, and is expected to deliver 3,900 feet of water a second into a spillway near Table Rock, close by the edge of the high bank. From that point the water will be taken by penstocks to a power house at the water’s edge in the gorge, very close to the base of the old waterfall. In this station the unit of development will be io.ooo-horsepower and the water from each of the three steel flumes is expected to develop (early next summer) 60,ooo-horsepower.
