Subdivisions a a are intended for grain to be cleaned; b b for grain ready to be loaded into railway trucks. Silos c c are for damp wheat, and are furnished with steam pipes for drying purposes. Silo Granaries at the Sun Flour Mills, Bromley by-Bow.—This is one of the earlier installations of this class, and affords an excellent illustration of the timber silo. Figs. 978 and 979 clearly indicate the general arrangements of this warehouse. The wheat is distributed by adjustable barge elevators, ordinary elevators, and band and worm conveyors. The granaries in question are situated on the river Lea, and are placed by that Fig. 978. Cross Section through Silo Warehouse and Receiving Station of Granary, Bow. waterway in direct connection with the Thames ; whilst the Lea flows by one side of the mills, the other side is served by another waterway known as the Limehouse New Cut. The mill is separated from the wheat warehouse by fireproof walls and iron doors. The grain receiving and handling plant was manufactured by Messrs Thomas Robinson & Son., Ltd., Rochdale. Fig. 978 shows a cross section through the receiving elevator, the preliminary cleaning, and the silos themselves. In the silo warehouse itself the grain is distributed by means of a band conveyor which runs under the apex of the roof, and which has a throw-off carriage which is shown in Fig. 979. By means of a system of spouts the grain can be deposited in any of the silos. The installation consists of thirty-three silo bins, each being 36 ft. deep and 9 ft. square. The walls of each silo are constructed on the American “ Cribwork ” system, which
