Now as the ground in the city of New York, to which water ought to be conveyed to a principal reservoir, is about forty feet above high tide, which is ten feet only below the level of the river Bronx, where it may be diverted, I consider it a fall perfectly inadequate to any design of conveying the water in a line of pipes it then becomes ne- ;

cessary, that the water of the Bronx should be elevated by the means of some machinery."

By this plan the water was to be elevated eighty feet above the level of Harlem river ;

the machinery for the purpose, was to be propelled by the surplus water from the Bronx, which was estimated to discharge 1200 cubic feet, or 7400 ale gallons per minute.
