seven years of valuable time, and there is therefore no other 

 way to make up for it but to proceed in the manner I have 

 indicated. 



In order to confine the statement of costs of the various 

 works and services within reasonable limits, I have con- 

 verted the whole of such costs shown in the Table in 

 appendix into pounds per day. 



The cost of the water in Columns "J," "P," and "V" 

 is given in pounds per million gallons, and as consumers 

 have to pay for water at a rate of pence per thousand gal-

 "K,""Q"and"W." 



Column "K" shows the total cost in pence per thousand 

 gallons of the water delivered to Crown Street and Ryde by 

 gravitation only. Column "Q" shows the total mean cost 

 in pence per thousand gallons of the water delivered to 

 Crown Street and Ryde by gravitation, plus the total mean 

 cost of pumping it to the higher zones. 



Column "W" shows from the year 1922, when pumping 

 would cease, the total mean cost in pence per thousand gal- 

 lons of all the works included in the costs shown in Column 

 "Q," less the cost of the additional works of the Prospect 

 Scheme shown in Column "E," less also the cost of pump- 

 ing shown in Columns " M " and " N, " plus the cost of all 

 the work included under my proposal shown in Column 

 "R." 



Column "X" shows the excess or deficiency in the cost 

 per thousand gallons when comparing the cost of the water 

 delivered under my proposal shown in Column "W," with 

 the cost of the water gravitated and pumped as shown in 

 Column "Q." 



An inspection of Column "X" shows that, notwithstand- 

 ing the heavy expenditure which will be necessary for the
