In case of mishap the economiser may be cut out of use, the flue gases being conveyed to the chimney by means of a bye pass, or auxiliary flue, and the feed water being pumped direct into the boilers without passing through the economiser tubes. Two feed water filters are supplied and all water passes through one or other of these before entering the boilers.

As the work was being carried out Messrs. H. P. White, M. W. Slade, H. W.
the best site obtainable in all other respects this difficulty had to be overcome, and efficient foundations were obtained by the driving of over five thousand piles. These were spaced so as to support the whole weight of the buildings themselves, the ground, which greatly varied in solidity, being left as an additional factor of safety. China fir poles, 15 feet in length and 5 inches in diameter, were used for the buildings and machinery, special 7-inch poles 18 feet in length being used for the chimney foundations. The depot comprises engine-room and basement, boiler-house, cars-hed and machine- shop, smithy, paint-shop and carpenters'-shop, and also offices. The engine room, which is lofty and well lighted, contains two continuous current, direct connected railway generators of the multipolar type, compound wound, giving a potential of 550 volts, and making 100 revolutions per minute. They are designed to run either separately or parallel. The genera tors are keyed direct on the main shaft of the engines, which are of the horizontal cross compound type, each engine being equal to a maximum load of 557 brake horse power. The engines, built by Yates and Thom, are each provided with a Wheeler surface condenser of the Admiralty pattern, and may be worked either condensing or non-condensing. condensed steam is conveyed to the hot well to be again used for boiler feed. The condensers are fixed in the basement below the engine room, as also are all the steam, exhaust, circulating and other pipes, thus leaving the engine room free and open. Circulating water for the condensers is obtained from the Bowrington Canal, which is alongside the site, the water first passing through pumps fitted with gratings and strainers to exclude obstructions.

The boiler house, which is at a lower level than the engine room, contains two double drum, water-tube boilers of the Babcock and Wilcox type, arranged to burn ordinary Japanese engine slack. Each boiler has 3,654 square feet of heating surface, evaporates 12,000 lbs. of water per hour, and works at a pressure of 160 lbs per square inch. In addition to the steam and water ganges each boiler is fitted with a spring safety valve and a dead weight safety

Dr. Jordan had no objections, he was simply going on a point of order. They had passed the rule giving the Committee power to add to their number, and he did not think that the present meeting had anything to do with the election of the additional members.
