The time of residence is shortened for persons who have served in the army or navy of the United States, and any such person may homestead 160 acres of land valued at $2.50 per acre. Any citizen may take advantage of both the homestead and preëmption privileges. Under the timber culture act, any citizen who is the head of a family may acquire title to 160 acres of land in the prairie region by cultivating timber thereon in certain specific quantities; the title can be acquired at the expiration of eight years from the date of entry. Any citizen may acquire title to one section of desert land (irrigable lands as described in this paper) by the payment at the time of entry of 25 cents per acre, and by redeeming the same by irrigation within a period of three years and by the payment of $1 per acre at the expiration of that time, and a patent will then issue. Provision is also made for the disposal of public lands as town sites. From time to time land warrants have been issued by the Government as bounties to soldiers and sailors, and for other purposes. These land warrants have found their way into the market, and the owners thereof are entitled to enter Government lands in the quantities specified in the warrants. Agricultural scrip has been issued for the purpose of establishing and endowing agricultural schools. A part of this scrip has been used by the schools in locating lands for investment. Much of the scrip has found its way into the market and is used by private individuals. Warrants and scrip can be used when lands have been offered for sale, and preëmptors can use them in lieu of money. Grants of lands have been made to railroad and other companies, and as these railroads have been completed in whole or in part, the companies have obtained titles to the whole or proportional parts of the lands thus granted. Where the railroads are unfinished the titles are inchoate to an extent proportional to the incomplete parts. With small exceptions, the lands of the Arid Region have not been offered for sale at auction or by private entry. The methods, then, by which the lands under consideration can be obtained from the Government are by taking advantage of the preëmption, homestead, timber culture, or desert land privileges.
