_The Socialist Labor Party_, organized in 1892, advocates government ownership of land, railways, telegraph lines, and other means of production and transportation. _The Socialist Party_, organized in 1904 mainly from the Socialist Labor party, advocates essentially the same views. At the election of 1912 it cast about 900,000 votes throughout the country, and in 1916 about 600,000. In 1919 a large section of the party, composed of radicals who advocate the Bolshevist régime of government by the working class, split off and formed the _Communist Party_. =Party Organization.=--Political parties, like other associations which have ends to promote, must have organization. For the conduct of national campaigns, each of the parties has a national organization; for state purposes there is a state organization; and usually there are a county and a district organization. The characteristic feature of party organization is the use which is made of committees. The organization everywhere consists of a committee, at the head of which is a chairman, and which has also a treasurer and usually a secretary. The chairman is usually an experienced political leader; sometimes he is at the same time an office holder. _The Convention._--The policies of the party are formulated by a convention which is a representative gathering composed of delegates chosen directly by the members of the party or by local conventions. The national convention, to be described hereafter, is composed of a certain number of delegates from each state, while the state convention is composed of delegates chosen from the counties, the legislative districts, or other units. The county convention is composed of delegates from the districts into which the county is divided, and the city convention of delegates from the wards or precincts. This is the usual rule, but here and there are variations. The state convention formulates the principles of the party and sets them forth in a document called the platform; it nominates the candidates of the party, except in those states where they are nominated by a direct primary; and it appoints the central committee, selects the chairman, and transacts such other business as may come before it. It is, in short, the supreme sovereign authority of the party in the state. It is usually a large body, sometimes comprising 1,000 or more delegates, and in Massachusetts as many as 2,000.
