The Government of Argentina is that of a Federal rather than a Centralized Republic, although in fact the President has a preponderating influence, with certain rights of intervention in the affairs of any Province. The constitution following quite closely that of the United States, there are the three usual branches. The President of the Republic, elected for a term of six years, is not immediately eligible for reëlection. Congress has a Senate of 30 members and a Chamber of Deputies of 158. The Provinces have each a Governor and a Legislative Assembly of its own choosing. The Governors of Territories are appointed by the President. A Territory has the privilege of becoming a Province when it has 50,000 inhabitants, but for some reason this right has not been exercised. The Federal District, the City of Buenos Aires, is governed by a Mayor and a Council elected by tax paying residents. Male citizens have the right of suffrage at the age of 18. The passage of a law, at the initiative of President Dr. Roque Saenz Peña, made the exercise of the franchise obligatory upon all native born citizens, and on foreigners after two years of residence, thus inaugurating a great change. At the first election under the new law in 1916, Dr. Hipolito Irigoyen of the Radical Party was chosen President by the Electoral College, the first person outside of the previously governing class to be elected. There are 14 Provinces corresponding to our States, and 10 Territories, besides the Federal District, Buenos Aires. The best obtainable figures of the area and population of the Provinces and Territories with those of the population and altitude of their capitals follow. The Provinces are named in order from the north across from west to east in four rows, thus beginning at the northwest:
