The generators are of the vertical type. They are mounted above the waterwheels, each nine feet in diameter, which keep them turning at the highest permissible speed. The wheels are encased in steel, and we can see nothing but their outer shell. A muffled roar is the only sign of the mighty force they are creating. It is difficult to realize that such tremendous energy can be completely tamed and working in harness, and we shiver as we wonder what would happen if one of these mechanical Titans should suddenly break loose. Each generator is a huge affair, as tall as a four-story house, and a rope eighty feet long would hardly reach around it. Its largest portion weighs more than three hundred tons. It reminds us somewhat of a merry-go-round, only in this case the whirling portion is all inside, and turning so fast that it seems to be standing still. It is so big that it would take thirty men, standing close together, to encircle it, and it is making one hundred and eighty-seven and one half revolutions a minute. We look through a little window in the bearing case and see a miniature lake of two hundred gallons of frothing oil that furnishes lubrication. So much heat is developed in the operation of the generator that cold air must be fed to it. In warm weather, it requires thirteen hundred and eighty thousand pounds of air every two hours and a half, or exactly as much as the total weight of the generator itself. In winter the air warmed by the generators is utilized for heating the power station. On the trip down to Niagara Falls from Toronto I had an opportunity to see something of what cheap power has done for southwestern Ontario. I passed through Hamilton, a place of more than one hundred thousand inhabitants, with plants operated by Niagara. Here are a large number of American branch factories using electric current that costs them less than fifteen dollars per horse-power per year. As in London, Windsor, Brantford, Kitchener, and other towns, the manufacturing establishments of Hamilton are increasing in number and size, and the people say that one of the chief reasons for their prosperity is the “Hydro” power system. In riding over the country I was struck with the well-cultivated farms and the attractive homes. I passed through the heart of the Niagara fruit district, which yields rich crops of grapes, apples, peaches, and other fruits. Most of the farmers now have electricity to help them with their outdoor work and lighten the labours of their wives as well.
