Even at this we are using less than our share, as we do not wish to take away from the beauty of the falls by lessening the volume of water that passes over them, our total consumption being only about sixteen thousand cubic feet per second. As our country grows and we need more light, fuel, and power, this question as to the use of the falls will become more and more important. The total power now going to waste every year equals many million tons of coal. The black coal once burned cannot be ...replaced, but this white coal, as water power has been named, comes on just the same year after year. Therefore, some think we ought to get more power from Niagara, and save our coal for the future. 280 NIAGARA IN HARNESS 281 And now let us see what Niagara in harness is doing. The amount so far employed by both countries is less than a half million horsepower, but this serves to run many great factories at Niagara and to light and give power to cities and towns many miles from the falls. By means of the cheap electricity so generated, one factory at Niagara makes a grinding material called carborundum, which takes the place of grindstones, emery, and diamond dust.
