_Extent of the Legislative Power._--In spite of the numerous restrictions, however, the power of the legislature is very large. It enacts the whole body of criminal law of the state; makes laws concerning the ownership, use, and disposition of property, laws concerning contracts, trade, business, industry, the exercise of such professions as law, medicine, pharmacy, and others; laws relating to the government of counties, towns, cities, and other localities; laws concerning the public health, education, charity, marriage and divorce, and the conduct of elections; laws concerning railroads, canals, ferries, drainage, manufacturing, eminent domain, and a great variety of other matters. The subjects concerning which the legislatures may enact laws are indeed so numerous and varied that it would be impossible to enumerate them all. For that reason the legislature is by far the most important branch of the state government, and it is highly important that it should be composed of honest, intelligent, and efficient members. Unfortunately, however, in many states the legislature has declined in public esteem. In the early days of our history the legislative branch of the government was all-powerful. It was not only practically unlimited as to its power of legislation, but it was intrusted with the choice of many important officers of the state. Now, however, there is a disposition to cut down its powers and place restrictions on the exercise of those that are left to it. In many states the people have secured the power to legislate for themselves by means of the initiative and referendum (pp. 85-89); and, to diminish the power of the legislature to enact useless laws, many constitutions limit the length of the sessions to forty or sixty days in the hope of compelling it to devote its time to the consideration of important measures of general interest. =Structure of the Legislature.=--Every state legislature to-day consists of two houses. At first several states followed the example of the Congress of the Confederation and tried the single-chamber system, but they soon found its disadvantages serious, and substituted legislatures with two houses. The principal advantage of a bicameral legislature is that each house serves as a check upon the haste of the other and thus insures more careful consideration of bills. Nevertheless, proposals have recently been made in several states to establish a single-chambered legislature, and the question was voted on by the electors of Oregon in 1912 and in 1914, and by those of Arizona in 1916.
