manufactured by the British Electric Company circulated the air over the coils and through the rooms. The motive power was derived from "National" Suction Gas Engines, and that gas plant worked with complete smoothness during the whole exhibition period, for a nine hours dailyf average, without a single hitch of any kind, we are assured, though in

the hands of a driver who was making his first acquaintance with a suction gas plant. There were two complete suction gas producer plants and engines working in this exhibit. One was a 20 B.H.P. plant and drove the four L,inde freezing machines already mentioned. In addition it drove a 2-inch Gwynne centrifugal pump, raising water from a well to a height of 30ft. to supply ammonia con-

denser and gas plants. It also drove a 3in* an' 1 a 4-in. Gwynne centrifugal pump as exhibits, circulating water up to a tank and from it. The other plant included a 6 B.H.P. " National" engine direct coupled to a dynamo manufactured by the Electromotors, Limited, of Manchester. This supplied the current for an electrically illuminating sign of 90 lamps and two Brockie-Pell arc lamps, which most effectively illuminated the whole exhibit. We are assured that this plant did not cost more than one penny per hour for fuel. The slight attention it got and the cost of fuel were matters of general comment. , ■ The well known Gwynne centrifugal pump was another of this firm's exhibits. The type, by the way, was chosen by the advising engineers at the exhibition for fire prevention purposes, and two specimens (of 4") were installed near the river bank in front of the exhibition, with a capacity between them of 1,000 gallons per minute. At Messrs. Niven & Co's court four were shown to great advantage. The work these pumps have done in connection with many irrigation schemes throughout the world is familiar to every engineer. We understand there are Gwynne pumps working now in New Zealand which^- J have been working for over forty years without any repairs ! Messrs. Gwynne' s Limited., claim to have manufactured pumps during the past fifty years of an aggregate capacity of 80 million gallons per minute ! The firm also showed a fine eight H.P. stationary engine from the works of Messrs. Brown and May, the famous engineers of Devizes ; it was a highly finished specimen mounted on a concrete foundation covered

by Arkilite, of a dark grey colour with a beautiful smooth polish. They had also a useful four horse traction engine from the same works in the exhibition grounds. Another couple of their exhibits was a Blackman ventilating fan and a KeithBlackman forge blower, which attracted considerable attention. Of these the former drew from many visitors the remark that no building need now be badly ventilated ; and exports freely expressed the opinion that with the electric current now available in most of our large towns the advantages of the electric forge blower for industrial purposes wotld be incontestible. This one was exhibited in full working order, and there was a supply of descriptive pamphlets in stock, freely distributed by the exhibitors, who were always ready to give every information on the subject. There were likewise in this court many samples of steam and water fittings from Messrs. Isaac Story and Sons (limited) of Manchester. And one of Goodwin Barsby & Co's coke breakers was shown at work breaking coke for the gas producer plants. lastly there was a fine show of electrical goods manufactured by various English firms — two Brockie-Pell arc lamps and a quantity of carbons manufactured by the Brockie-Pell Company, L,td., one 5-h.p. 220 volt B type starter, 1 motor starting panel, etc., manufactured by Brook, Hirst and Co., London, 1 black marble switch board moun-

ted in polished teak manufactured by Nalder Bros, and Thompson, London. All the belt drives (in all about 300 feet) were of patent Linkum belting, supplied by Messrs. Booth & Budd, of Wellington. The background in the painting of building, signboards, etc., was white, the lettering mostly in gold, black and red. The total space occupied by building and plant was 78 feet frontage by 20 feet. The machinery space was enclosed by a two-inch polished brass rail supported by polished posts, and the whole made a very comprehensive exhibit of working machinery / well laid out and finished off in a style creditable to all concerned. One feature much commented on was that all the exhibits in this stand were of British manufacture. Our illustrations give a fair idea of the firm's fine up-to-date establishment at Napier, which is in touch with the various manufacturers, and of the work it does on its own account. They present various phases of an industrial entei prise very useful to the State and most creditable to its promoters.
