CXXIV. DISCUSSION. 
has given the prestige of his name to ideas that are not 
practicable and may mislead. It would be more satisfactory 
if Mr. Scott gave some details of the capital cost of his 
suggested schemes, so that a comparison could be made 
with steam or gas driven plants, and then it could be seen 
whether the stoppage of supply during drought, to which 
he refers as being of apparently only of small importance, 
would be more than compensated for by the great saving 
that would result from cheaper power. 
In the above remarks I may have taken a very conser- 
vative view, but that does not lessen my appreciation of 
the work done by those who have proposed these big 
schemes of harnessing water, which would otherwise flow 
to waste to the machines in a factory a long distance 
away, and our thanks are due to Mr. Scott for bringing the 
subject before us.
