51. Four per cent. of the annual rateable value would realize $9,033 per annum, and on the assumption that 10 gallons per head were used for domestic purposes would make the price paid 18 cents per 1,000 gallons.

52. It will, therefore, be seen that a charge for water supplied by meter of 25 cents per 1,000 gallons, and an allotment of 4 per cent. per annum on the rateable value of the districts supplied to water works purposes would probably yield an annual revenue of $11,314, leaving a balance of $2,904 per annum, in order to pay off the cost of the works now proposed in 20 years and meet the annual cost of maintenance, to be defrayed from other sources or from the revenue derived from an increased rateable value or increased supply by meter in the future.

53. The estimated quantity of water available to meet these further demands without increased expenditure on works is 74,950 gallons per diem, or 27,356,750 gallons per annum.

REMARKS. The albumenoid ammonia figure is rather high, but the other features in the analysis are so satisfactory as to

indicate that it is not of an objectionable origin.
