IN few if in any departments of civil or industrial life has applied science introduced more revolutionary changes in the last hundred years than in that of transport. It would be difficult, however, to find any other aspect of civil life which has been allowed to develop along more haphazard lines or in which the utilisation of the results of scientific discoveries has been more divorced from scientific organisation and control. One and a half million people, or nearly eight per cent of the employed population of Britain, are directly engaged in one or other of the branches of transport. Regarded solely as an industry, it is, therefore, of the utmost importance that efficient management and wise administration should maintain the highest possible standard of efficiency and economic development of the transport industry. Prom the wider view of transport as an integral and indispensable part of the national structure, it is impossible to exaggerate the importance of adequate, efficient, and cheap transport facilities, particularly in a country such as Great Britain, in which trade consists so largely in the importation of food and raw materials and the exportation of manufactured goods.
