When towns grow large the town meeting becomes unwieldy and the system of administration by numerous boards fails to work smoothly. For this reason some New England towns have recently adopted a “limited town meeting” system, by which the voters of the town elect delegates to represent them in the town meeting. A few towns have also abolished the various administrative boards and have placed town administration in charge of a town manager appointed by the selectmen.[64] =The Township.=—In the great group of Central and Middle Western states, ranging from New York and Pennsylvania to Nebraska and the Dakotas, the principal area of community government is the township, although it is sometimes called the town. In the older states these townships (or towns) are of irregular shape; in several of the newer states the so-called “congressional” townships were laid out in uniform blocks, six miles square. In some of the states, both old and new, the towns or townships have town meetings, as in New England, but nowhere outside of New England have these meetings attained any great importance. Their chief function in the Central and Middle Western states is to elect the town or township officers. The work of township (or town) administration is carried on either by a board of trustees or by a single official commonly known as a supervisor. There are also various subordinate officials, all of whom are usually elected by the voters. =The County Districts.=—In most states of the South and Far West there are no townships. The county remains the principal area of local government, but for the management of various community affairs the county is divided into districts. There are school districts, road districts, and election districts, for example. Each district has its own elective officers who are in charge of the function for which the district was established.
