Grand Junction 12,601 15 ---------------------- Difference 7,857,646 11 ---------------------- If, therefore, the independent canal companies, having a waterway from the colliery district of the Midlands and the North through to London (without, as already stated, any section thereof being controlled by railway companies), had improved their canals, and doubled, trebled, or even quadrupled the quantity of coal they carried in 1889, their total would still have been insignificant as compared with the quantity conveyed by rail. [Illustration: "FROM PIT TO PORT." (Prospect Pit, Wigan Coal and Iron Company. Raised to the surface, the coal is emptied on to a mechanical shaker, which grades it into various sizes--lumps, cobbles, nuts, and slack. These sizes then each pass along a picking belt--so that impurities can be removed--and fall into the railway trucks placed at the end ready to receive them. The coal can thus be taken direct from the mouth of the pit to any port or town in Great Britain.) [_To face page 82._ ] The reasons for this transition in the London coal trade (and the same general principle applies elsewhere) can be readily stated. They are to be found in the facilities conferred by the railway companies, and the great changes that, as the direct result thereof, have taken place in the coal trade itself. Not only are most of the collieries in communication with the railways, but the coal waggons are generally so arranged alongside the mouth of each pit that the coal, as raised, can be tipped into them direct from the screens. Coal trains, thus made up, are next brought to certain sidings in the neighbourhood of London, where the waggons await the orders of the coal merchants to whom they have been consigned. At Willesden, for example, there is special accommodation for 2,000 coal waggons, and the sidings are generally full. Liberal provision of a like character has also been made in London by the Midland, the Great Northern, and other railway companies in touch with the colliery districts. An intimation as to the arrival of the consignments is sent by the railway company to the coal merchant, who, in London, is allowed three "free" days at these coal sidings in which to give instructions where the coal is to be sent. After three days he is charged the very modest sum of 6d. per day per truck. Assuming that the coal merchant gives directions, either within the three days or later, for a dozen trucks, containing particular qualities of coal, to be sent to different parts of London, north, south, east and west, those dozen trucks will have to be picked out from the one or two thousand on the sidings, shunted, and coupled on to trains going through to the stated destination. This represents in itself a considerable amount of work, and special staffs have to be kept on duty for the purpose.
