. The agricultural gazette of New South Wales. Agriculture; Agriculture -- Australia New South Wales. Nov. 2, Agricultural Gazette of W, 875. The larger plants were stimulated into a vigorous growth by electric rays, under the Thwaite System at the Royal Botanic Gardens.—Illustration from T/ie .Scitdtino 4/iitTicaii. connected with a dynamo, from whence the electric current is conveyed to the travelHng arc lamp. An electrostatic machine, wliich charges the atmosphere, the plant and roots, is driven from the gas-engine crank shaft ; in fact, the whole requirements of heating, feeding, and lighting are supplied by the gas-engine. Excellent results have been obtained both with vegetables and flowers, and from three to four seasons are attainable during the year. In regard to the cost of working a glass-house under the Thwaite system, apart from the initial outlay it is said to be absurdly low ; indeed, it is asserted that the whole expense of the apparatus and its working is about one-third that of the ordinary glass-house process. Similar experiments to those of Mr, Thwaite have been made with a A^ariety of plants at the Cornell University Agricultural Station in America. These have shown that the system does not benefit all plants equally, but that in regard to method of treatment they must be considered individually, and classified accordingly. The cauliflower proved absolutely unresponsive to the new stimulus under the conditions in this test; while from the lettuce most striking results were obtained, plants of the best quality being ready for market ten days earlier than by the ordinary glass-house process. That electric light is a valuable aid in forcing and perfecting both market garden and horticultural produce is so far recognised that many American gardeners have already found its introduction distinctly Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - colo
