TI PORT ECONOMICS independent but allied organization, a notable installation of warehouses, stores and industrial concerns, has been effected. Goods are conveyed by rail from the quayside to any place in Trafford Park at a uniform rate of 6d. per ton. CARDIFF Besides being a representative port for Wales, Cardiff has a special claim to distinction as the leading port for the shipment of coal, not only in Great Britain, but in the world. It is the centre of the South Wales coal trade and is flanked by neighbouring ports which also do a notable business in coal. Coal and coke exports from Cardiff have exceeded 26 million tons (in 1913), and though there have been necessarily wide fluctuations lately, due to various causes, yet under normal conditions such exports may be put at about 20 million tons. It is a feature of the Cardiff docks, therefore, that the quays are equipped with special appliances for shipping coal—hoists and tips, capable of dealing with loads up to zo tons. Formerly a very large proportion of the wagons engaged in the coal-mining industry could only convey loads of 10 tons, and most of the quayside appliances were also limited to this figure, but, of late, the forward policy of the Great Western Railway in offering special advantageous terms to the colliery proprietors for the use of 20-ton wagons has resulted in a general raising of the standard. The quayside appliances have been adapted to meet it. But Cardiff is not merely a coaling port. There is an important import trade in pit props and various kinds of timber, as well as in grain and iron ore. The densely populated area in the vicinity of the port requires a steady influx of foodstuffs, and Cardiff has attained the position of the third largest milling centre in the country. There are important iron and steel works in the neighbourhood consuming a continuous supply of ore. The tinplate Cy)
