_Commerce._--The foreign trade of Bolivia is comparatively unimportant, but the statistical returns are incomplete and unsatisfactory; the imports of 1904 aggregated only L1,734,551 in value, and the exports only L1,851,758. The imports consisted of cottons, woollens, live-stock, provisions, hardware and machinery, wines, spirits and clothing. The principal exports were (in 1903) silver and its ores (L636,743), tin and its ores (L1,039,298), copper ores (L157,609), bismuth (L16,354), other minerals (L20,948), rubber (L260,559), coca (L28,907), and cinchona (L9197)--total exports, L2,453,638. These figures, however, do not correctly represent the aggregates of Bolivian trade, as her imports and exports passing through Antofagasta, Arica and Mollendo are to a large extent credited to Chile and Peru. The import trade of Bolivia is restricted by the poverty of the people. The geographical position limits the exports to mineral, forest and some pastoral products, owing to cost of transportation and the tariffs of neighbouring countries. _Government._--The government of Bolivia is a "unitarian" or centralized republic, representative in form, but autocratic in some important particulars. The constitution in force (1908) was adopted on the 28th of October 1880, and is a model in form and profession. The executive branch of the government is presided over by a president and two vice-presidents, who are elected by direct popular vote for a period of four years, and are not eligible for re-election for the next succeeding term. The president is assisted by a cabinet of five ministers of state, viz.: foreign relations and worship; finance and industry; interior and fomento; justice and public instruction; war and colonization. Every executive act must be countersigned by a minister of state, who is held responsible for its character and enforcement, and may be prosecuted before the supreme court for its illegality and effects. The legislative branch is represented by a national congress of two houses--a Senate and Chamber of Deputies. The Senate is composed of 16 members, two from each department, who are elected by direct popular vote for a period of six years, one-third retiring every two years. The Chamber of Deputies is composed of 72 members, who are elected for a period of four years, one-half retiring every two years. In impeachment trials the Chamber prosecutes and the Senate sits as a court, as in the United States. One of the duties of the Chamber is to elect the justices of the supreme court. Congress meets annually and its sessions are for sixty days, which may be extended to ninety days. The chambers have separate and concurrent powers defined by the constitution. The right of suffrage is exercised by all male citizens, twenty-one years of age, or over, if single, and eighteen years, or over, if married, who can read and write, and own real estate or have an income of 200 bolivianos a year, said
