To prevent the legislature from creating new counties or altering the boundaries of existing counties against the wishes of the inhabitants, and to secure to the people home rule in such matters, the constitutions of a number of states provide that new counties may be formed, or the area of existing counties altered, only with the consent of the inhabitants concerned, given by a direct popular vote on the question. _Functions of the County._--The county is a judicial and elective district, and the jails and courthouses and sometimes the almshouses are county rather than town institutions. Outside of New England the county is also often the unit of representation in the legislature; and it acts as an agent of the state in collecting taxes and executing many laws. =County Officers.=--_The County Board._--The principal county authority is usually a board of commissioners or supervisors (in Louisiana it is called the police jury), elected by the voters either from the county at large or from districts into which the county is divided. In most states it is a small board, usually three or five members; in some it is larger, being composed of one member from each township in the county. In a few Southern states (Kentucky, Tennessee, and Arkansas), the county court of justices of the peace still acts as the county board, as in Colonial days. This board is both a legislative and an administrative body for the county, for the executive and legislative functions in local government are not always kept so separate and distinct as they are in the state and national governments. It levies taxes, appropriates money for meeting the public expenses, has general control of county finances, has charge of county buildings and other property, settles claims against the county, approves bonds of county officials, and in many states it establishes roads, lets contracts for the erection of bridges and other public works and for repairing them, licenses ferries and sometimes inns, saloons, peddlers, etc., cares for the poor and dependent classes, and performs numerous other services which vary in extent and character in the different states.
