The water power created,’ is calculated to be equal to 
raise into the reservoir by eight wheels and pumps,upwards 
of ten millions of gallons per diem. e river, in the dry 
season, will afford four hundred and forty millions ev 
twenty-four hours;—andas it is calculated, that forty gallons 
upon the wheel will raise one into the reservoir—eleven 
million of gallons may be raised each day. 
Many interesting particulars, detailed in the last report

of such an elevation as to afford the hydrostatic pressure 
of ninety-two feet, throwing upon the pumps a pressure of 
seven thousand nine hundred pounds. ‘There are two re- 
servoirs, one of which is one hundred and thirty-nine feet -
