The government is a centralized republic, based on the constitution of 1860, revised in 1920. The President is now elected for five years; he is ineligible for immediate reëlection. The other two branches of government are of the usual form. Congress has two Chambers, a Senate of 35 members and Deputies 110, both elected by direct vote. Alternates are chosen to assume office in case of vacancy. There are also three local legislatures. The President appoints the Prefects of Departments and the Sub-prefects of Provinces; the Prefects name the _Gobernadores_ of the Districts. The President controls the police of the country; the supervision of education is centralized. The Judiciary has a Supreme Court at Lima, nine Superior Courts in the chief cities, and Lower Courts in smaller places.
