3. The Local Government Board may, by order, dissolve any special drainage district constituted either before or after the passing of the Public Health Act in which a loan for the execution of works has not been raised, and merge it into the parish or parishes in which it is situated; but in the cases where a loan has been raised the Local Government Board can only do this by provisional order (Public Health Act, sec. 271).

Disputes with regard to the boundaries of districts are to be settled by the Local Government Board after local inquiry (Public Health Act, sec. 278).

Where districts also are constituted for the purposes of main sewerage only, in pursuance of the Public Health Act of 1848, or where a district has been formed subject to the jurisdiction of a joint sewerage board, in pursuance

of the Sewage Utilisation Act of 1867, such districts or district may be dissolved by provisional order, and the Local Government Board may constitute it a united district, subject to the jurisdiction of a joint board (Public Health Act, sec. 323).

The Local Government Board may also declare by provisional order any rural district to be a local government district.

The Local Government Board has also the important power of investing a rural authority with urban powers as follows:

“The Local Government Board may, on the application of the authority of any rural district, or of persons rated to the relief of the poor, the assessment of whose hereditaments amounts at the least to one tenth of the net rateable value of such district, or of any contributory place therein, by order to be published in the ‘London Gazette,’ or in such other manner as the Local Government Board may direct, declare any provisions of this Act in force in urban districts to be in force in such rural district or contributory place, and may invest such authority with all or any of the powers, rights, duties, capacities, liabilities, and obligations of an urban authority under this Act, and such investment may be made either unconditionally or subject to any conditions to be specified by the board as to the time, portion of its district, or manner during, at, and in which such powers, rights, duties, liabilities, capacities, and obligations are to be exercised and attach, provided that an order of the Local Government Board made on the application of one tenth of the persons rated to the relief of the poor in any contributory place shall not invest the rural authority with any new powers beyond the limits of such contributory places” (Public Health Act, sec. 276).

Powers and Duties of Sanitary Authorities. In England urban sanitary authorities have very extensive powers and duties under the Public Health Act of 1875, and in addition they have to carry out the Bakehouse Regulation Act, and the Artisans’ and Labourers’ Dwellings Act. They also have power to adopt the Baths and Wash-houses Acts, and the Labouring Classes’ Lodging Houses Acts; but where adopted or in force, the powers, rights, duties, &c., of these Acts belong to the urban authority. The powers of any local act for sanitary purposes (except a River Conservancy Act) are transferred to the urban authority.

The powers of an English rural authority are exercised principally under the Public Health Act, but they have also to carry out the Bakehouse Regulation Act.

The powers given by the Irish Public Health Act to Irish Sanitary Authorities are similar.
