THE LOCAL AUTHORITIES 279 real conflict between two ideals—the civic pride which is most easily aroused in a smaller compact area, and the desire for expert centralized administration. All the authorities so far described are general authorities, performing many duties. There remains a comparatively small number of ad hoc authorities, to manage ports and rivers, or to provide water supply. Some of these *are created by the joint action of the ordinary local authorities; on others, both the public authorities and private companies are represented. They are suitable for handling technical problems, but, as ipth century experience has shown* the multiplication of them leads to con- fusion. To-day, the Central Government finds a substitute for them by requiring that particular local authorities shall act as housing authorities, education authorities, and so on. Thus a Borough Council can be several authorities in one, e.g., a sanitary, a highway and an .education authority. It is for this reason that local authorities find it essential to divide into committees. The full working of this system, and its relation to the general problems of politics, can be best understood after a survey of the social services has been made. BOOKS: *j. J. CLARKE.
