=Frequency of New Constitutions.=--The frequency with which the states revise their constitutions varies in different sections of the country. In New England new constitutions are rare, while in the states of the West and the South new constitutions are framed, on an average, at least once in every generation and sometimes oftener. Since the Revolution more than two hundred constitutions have been made by the states, though some of them never went into operation. Several of the states within a period of less than one hundred years have had as many as six, and a few have had even more. The constitution of Massachusetts of 1780, with several subsequent amendments, is still in force; but outside of New England there are few constitutions that are more than thirty years old. Some of the states, indeed, have inserted provisions in their constitutions making it the duty of the legislature at stated intervals to submit to the voters the question of calling a convention to revise the existing constitution or to adopt an entirely new one. In this way the people are given an opportunity to determine whether the constitution under which they live shall be revised or superseded by a new one, independently of the will of the legislature. =Contents of State Constitutions.=--The early state constitutions were brief documents and dealt only with important matters of a fundamental and permanent character. They were remarkably free from detail and rarely contained more than 5,000 words. As time passed, however, there was an increasing tendency to incorporate in them provisions in regard to many matters that had formerly been left to the legislature to be regulated by statute, so that some of the constitutions of the present day are bulky codes containing detailed provisions concerning many matters that might more properly be dealt with by statute. The constitution of Virginia, for example, has expanded from a document of a few pages to one of seventy-five, from an instrument of about 1,500 words to one of more than 30,000. The present constitution of Alabama contains about 33,000 words; that of Louisiana, about 45,000; and that of Oklahoma, about 50,000. The Virginia constitution contains a lengthy article on the organization of counties; one on the government of cities, constituting a code almost as elaborate as a municipal corporations act; one on agriculture and immigration; one on corporations, containing fourteen sections; one on taxation and finance, etc. The constitution of Oklahoma contains an article of seven sections on federal relations, one of which deals with the liquor traffic; elaborate provisions regarding the referendum and initiative; a section describing the seal of the state; a detailed enumeration of those who are permitted to accept railroad passes; an article on insurance; one on manufactures and commerce; and one on alien and corporate ownership of lands.
