Geological changes are taking place so slowly that they need not be reckoned with as a probable destroyer of the Falls for ages yet to come. Moreover, their effect is treated in another chapter. The history of the Niagara Falls Hydraulic Power and Manufacturing Company, as a user of power from the Falls, antedates even its legislative recognition. Between the years of 1888 and 1894 nine companies were recognised or chartered in the State of New York. These charters were granted very freely, no revenue was required for the use of the waters, and in some cases no limitation was placed upon the amount to be used. Of these charters, all were granted in good faith; but it is very doubtful if all were received in that spirit. Some of the companies failed to effect an organisation, others offered to sell their rights as soon as obtained. Various limitations were put upon the time in which work must be begun. At least three of the charters have lapsed by their own time limitations, one franchise was sold by its original owners; one other shows at times faint signs of life; another is leading a questionable existence, while two, the Hydraulic Power and Manufacturing Company and the Niagara Falls Power Company, are producing and selling power. To these two organisations are to be credited the great industrial development on the American side and they are not yet using the amount of water allowed them by their charters. As a result, of course, the flow of water is of smaller volume; but this cannot be perceived by the casual observer. However, citizens of Niagara Falls insist that the decreased flow is manifested in other ways; such as the annual gorging of ice at the head of the American channel almost laying this channel bare and sending its water to the Canadian side. This happens very rarely with a normal depth. Besides this it became necessary not long ago to move the dock at which the _Maid of the Mist_ lands, the water line having retreated as a result of decreased volume. The two American companies are not expecting to diminish their consumption of water in any way. The growing demands for power have caused each continually to enlarge its plants. The Niagara Falls Power Company, realising the great growing demand for cheap power, has obtained a large interest in one of the Canadian companies. The amount of water which may be used by these companies according to charter limits is as follows: Niagara Falls Hydraulic Power and Manufacturing Co. 7,700 cu. ft. per sec.
