000,000 cubic feet; at this rate the cost per million cubic feet 

 stored would be $173.33, but with 25 per cent added to the esti- 

 mate to conform to conditions in 1901, the cost per million cubic 

 feet stored is $216.67. 



The main characteristics of the proposed reservoir are shown 

 bj table Xo. 83, condensed from pages 708-9 of the Report of the 

 State Engineer and Surveyor for 1896 :

Comparing the foregoing statements of cost with those made 

 on the preceding page with reference to the cost of the proposed 

 reservoir in Mount Morris canyon, it appears that at Portage a
