There are two classes of public lands subject to entry; one at $1.25 per acre, known as _minimum_, and one at $2.50, known as _double minimum_, the latter being the alternate sections along the lines of railroads. Title may be acquired by purchase at public sale, or by “private entry,” and in virtue of the Pre-emption and Homestead Laws. _At Public Sale._—Lands are offered at auction to the highest bidder, pursuant to proclamation or public notice. _Private Entry._—Lands subject to private entry, are those which have been once offered at public sale without finding purchasers. In order to acquire title to these lands, a written application must be made to the Land Register of the District in which the land is located, describing the tract desired. The Register certifies the fact to the Receiver, stating price, and the applicant then pays the money and takes a receipt, and at the close of the month the Register and Receiver make return of the sale to the General Land Office, when a patent or full title issues on due surrender of the receipt, and will be delivered at the option of the purchaser, at the General Land Office in Washington, or by the Register at the District Land Office. _Land Warrants._—When lands are to be located with land warrants, application must be made as in cash cases, accompanied by an assigned warrant. When the tract is $2.50 per acre, $1.25 per acre must be paid in addition to the warrant. Receipts are given and patents delivered, as in the preceding case. At the time of location, a fee of 50 cents for a 40 acre warrant, and a corresponding amount for larger ones, must be paid to the Register, and a like sum to the Receiver. _Agricultural College Scrip._—This may be used in the location of lands at private entry, but is only applicable to lands subject to entry at $1.25 per acre, and is restricted to a technical “quarter section,” and to three sections in each township of land. The proceeding to acquire title is the same as in cash and warrant cases, the fees being the same as on warrants. This scrip may be used in payment of pre-emption claims.
