Mr, T. STEWART, Engineer of the Table Mountain Reservoir Works, 
then read his paper on ‘Table Mountain as a Source of Water-power.’ 
Dr. GILL, after complimenting Mr. Stewart upon his paper, said they 
had an enormous source of power on Table Mountain, of which they at 
present made no practical use. They had never been able to arrive at 
an estimate of this power until this paper of Mr. Stewart’s was brought 
before them. He believed that Mr. Stewart had understated the actual 
power that could be obtained. He thought Mr. Stewart’s statements 
would draw attention to the fact that this power could be utilized for 
working the electric light in Cape Town. Parliament in its wisdom had 
seen fit to divide the principal part of Table Mountain into areas, one 
set of which were suitable for collecting rain-water, and the other for 
making reservoirs. To one set of municipalities they had given those 
suitable for making reservoirs, and to the other set those suitable for 
collecting the water, with the happy result that they could not both 
collect and store their water to the best advantage; and from the 
harmonious manner in which such people managed matters, it seemed 
that there might possibly be some difficulty in connection with this. 
He believed that there would be sufficient power with accumulators to 
run 10,000 electric lamps. He thought the subject was by no means 
threshed out, and that the Society might well revert to it on a future 
occasion.
