Авт. УШ. Notes on the Proposition to Supply Auckland with Water from 
Mount Eden. By James STEWART, С.Е. 
[Read before the Auckland Institute, 8th December, 1873.1 
AT last monthly meeting of this Society, Mr. Goodall read a paper in which 
the above proposition was pretty fully set forth, and a scheme for testing its 
feasibility stated in detail This is not, by any means, a new idea, as about 
eleven or twelve years ago it was proposed as original, and advocated with 
other three schemes for the same purpose. One of the schemes was, in sober 
earnest, a proposal to impound the water flowing down the valley of Newton, 
from the cemeteries; and the advocacy of the Mount Eden one showed 
equally the absence of all engineering thought or study. Mr Goodall’s paper 
dealt with it differently, and in a clear manner stated a method of testing the 
level and area of the supposed water basin. One grand point was, however, 
overlooked, just as the earlier propounder had done. While the existence of - 
water in wells near the base of Mount Eden is undisputed, and that at а 
tolerably high level above the sea, there is no attempt to show that there is a 
source of supply at all adequate to the demand. It is not only necessary to 
show a reservoir of water, but how much may be daily and yearly drawn from 
it without failure must also be demonstrated. Two lines of evidence are 
required to show the latter point in this ease, Firstly, the discharge of the
