A Large California Power Plant. The Great Western Power company, a syndicate owned by New York men, with Viccpresident Edwin Hawley of the Western Pacific railway as president, has been for some time quietly at work in the neighborhood of the Feather river —a very obscure region—on a big water-power plant. A tunnel 3 miles long and 18 1/2 by 20 ft. in the clear, through rock, all lined with concrete, has been completed. This is the greatest waterpower conduit in the world, and practically takes a whole river and runs it under a mountain 3,021 It. high. The power plant, when completed, will produce 120,000-horsepower. The biggest power plant now in California is not more than 25,000horsepower. Within a period of less than two years the Great Western Power company will have expended in California a first instalment of $ 10,000,000.
