THE LOCAL AUTHORITIES 275 satisfactory, half the expenses will be met by the Central Govern- ment. Subject to this control, the County Police are responsible for all police duties within their area. As readers of detective stories know, the Chief Constable may call in the help of the C.I.D., when the problem is one of special difficulty or requires nation-wide police action. To create so expert a body as the C.I.D., and then limit its work at the will of local authorities may seem a surprising procedure; it arises from the desire for local independence, and the reluctance to give executive power to anyone appointed by the Central Government.

The day on which an Urban District becomes a Borough is welcomed by local celebrations, attended by the Mayors of neighbouring Boroughs,
