One of the most spectacular sights in North America is to be seen at Grand Coulee Dam, where the overflow from the now-full Columbia River reservoir, impounded by the 1072 million cubic yard concrete structure, plunges over the giant spillway. Nearly 2,000,000 gallons of water fall over the man-made precipice with a tremendous roar every second. Power is being developed in a large power- house flanking the cataract, in which three 108,000 kilo- watt hydro-electric generators, largest ever constructed, have been assembled. MADE IN U, S. A C.
