The scheme of government thus provided for the northwest territory became the model for the later territorial governments. It was introduced into the southwest territory and later to the territory acquired west of the Mississippi River. =The Organized Territories: Hawaii and Alaska.=--The territories and dependencies of the United States may be grouped into two classes: the organized and the unorganized. A territory of the first class is said to be "organized" because it has its own local legislature, both houses of which are elected. At present the only territories of this class fully included as parts of the United States are Hawaii[105] and Alaska,[106] but since most of the states were organized territories before being admitted to the Union, this kind of government is of more than ordinary interest to the student of civics. [105] The Hawaiian Islands were annexed to the United States in July, 1898, by a joint resolution of Congress after a treaty of annexation had been rejected by the senate. The senate of Hawaii is composed of fifteen members, the house of thirty; ability to speak, read, and write the English or Hawaiian language is required of voters; the governor may veto special items in appropriation bills; and in case the legislature fails to pass appropriation bills to pay the necessary expenses for carrying on the government and meeting its obligations, the treasurer may, with the approval of the governor, make such payments, for which purpose the sums appropriated in the last appropriation bills shall be deemed to have been reappropriated; the purpose being to prevent the legislature from causing deadlocks. [106] For Porto Rico and the Philippines, see pages 374-379. _Executive._--In a fully organized territory there is a governor who is appointed by the President with the consent of the senate for a term of four years, and who enjoys the usual powers of a state executive. The appointment is usually made from the residents of the territory, though in a few cases outsiders have been appointed. There is also a secretary who keeps the records of the territory, compiles and publishes the acts of the legislature, and serves as governor during the absence or disability of the latter official. Other administrative officers of the territory are the attorney-general, treasurer, commissioner of public lands, superintendent of public education, surveyor, and auditor. _The Legislature_ is composed of two houses, both of which are popularly elected. Regular sessions of the legislature are held every two years and are limited to sixty days, though the governor may call extraordinary sessions with the approval of the President of the United States.
