CONCLUSION AS
TO AVAILABLE SUPPLY.
The annual supply will therefore be:-

The storage according to my computation won't
be 4.00 x 200 = 800.00 millions.
Mr Cooper proposes to provide

Modifications in details or in the order of exeqution may be made, from time to time, as experience may direct.

I have assumed that the available rainfall from gather- ing-grounds collected by outon-water channels, is the same as that of areas the flow from which runs naturally to the reservoirs. To carry off the great floods which sometimes occur, channels of impracticable size would be required. The whole of the reasoning is however based on the data obtained, during exceptionally dry seasons, during which exceptional floods are not to be expented. I venture to believe that, if the channels were made sufficiently large, to carry off" of rain on the gathering-ground which they intercept, they would in exoeptionally dry seasons, nonvey practically the whole
