The Thames-Hauraki Pumping Plant at Thames, New Zealand

THIS paper proposes to give a general description of the pumping and other machinery in use at the Thames Hauraki Pumping Station, situated on the Thames goldfields of the North Island, New Zealand. An idea of the general arrangement of the pumping engines and pumps can be obtained, together with a certain amount of detail, by reference to the illustrations. The history of the pump is rather interesting, and is as follows: -In 1894 the Government decided that a subsidy of £1 for £1up to an amoUllt not exceeding £25,000 be granted towards the erection of suitable machinery to exploit the Thames low levels.With a guarantee of such assistance a company was floated in London, with a capital of £300,000, to develop several properties at Thames. As the old Queen of Beauty Company had produced bullion worth £400,000 prior to closing down on account ofa breakdown to its pumping gear, their shaft was chosen as the site of the principal work. As soon as the company was floated, operations were commenced at the Queen of Beauty shaft, situated at the entrance of the Waio-Karaka Creek, and not more than about half a mile distant from the principal mines on the field.
