EVOLUTION OF THE WATER WHEEL. The essential principles of a well constructed water wheel are not unlike those of a finely balanced and ad- justed automatic cut-off steam engine. In either device the first considera- tion is a point of impact of the power with some vehicle through which the power is conveyed directly to the machines to be driven. In the steam engine this point of impact is the piston head, and the power is the steam ad- mitted to it through the cylinder. In the water wheel the point of impact is the bucket, and the power is the weight of water conducted to it. During the early stages of steam engine develop- ment the margin of profit in the use of steam over hand power was so enor- mous that little or no at- tention was given to economy of fuel; but with the expansion of competition which this large margin naturally invited, the minutest detail of cost of production came to be closely scanned, and to-day the quantity of fuel consumed in any well ordered manufacturing estab- lishment is as accurately noted as any other material that enters into the factory product, and vast sums are cheerfully paid for plants that secure the closest propor- tion between a certain weight of coal burned and each pound of water evaporated. Such scaling down in the cost of steam power for a time left vast water powers throughout the land com- paratively u
