ELECTRIC LIGHTING OF THE BOROUGH.

We publieh the f'-Uuwing letter as bei » the private opinio.. Fan electrical expm who knows Akaroa well , and the amount of water power at our command : — 'If ynu only require 25 horse poweUi 6in. pipes are ample under 236 feet bead. To obtain mora power you can e'.lher (1) put in larger pip'M under same head, or (2) bring the pow v atfttion lower down the treek, and so geb more head, and use the sma'.l:r pipe. If the supply *f water is at uil likely tv run short. I would strougly advise you to adopt io. 2 and have the power houee as close to t 6 sea as possible, 8 id so uae up as much of the 450 ft head R". possible. The total estimate given by Turnoull and Jones seems very high, and is out of of all proportion to the power supplied. If you like I will send you a complete estimate, as I am certain that I caG fully sUisfy your requirements afcaccn siderably lower figure, and with your excellent water supply the Council should mo.-t certainly arrange for a much larger amount lof power, and be prepared to supply it for all purposes. The power house would be much more centrally situated if it were lower dowu the creek, and this for supplying electricity is an immense advantage. Just to give you an idea of tbe power available, if you oan use a fall of 4CO feet, I imy ttll yon tint you caa easily obtain 500 horse power, and then you only require 800 cubic feet of water a minute, but this would take a large pipe cf two feet or more in diameter ; or with 400 feet head and 6in pij.es you oan get 50 horee power with ease, and probably more, as I have not make a careful estimate. Roughly speaking, 1 horse power will run ten 16-eandle power lamps, bo that 50 horeo power would give 500 lamps."
