MINING
HARNESSING WATER POWER. Mr J. Stephens, of Dunedin, claims to have designed a new method of harnessing water power for use in mining to secure greater efficiency, more particularly in elevating. As the result of a number of experiments, the inventor claims that by a simple adaptation the ordinary hydraulic plant can be improved in efficiency by at least 100 per cent. Not only is it claimed will this design widen the field for the profitable use of high pressure water power, but also that large volumes of low pressure water power, down to 15 feet of fall, will be able to lie harnessed efficiently to aid the winning of gold in a number of our unworked alluvial streams.
