20.  Parties having founded or who desire to found a city or town on the public lands must file with the recorder of the county in which land is situate a plat thereof, describing the exterior boundaries of the land according to the lines of public surveys.  Such plat must state the name of the city or town, exhibit the streets, squares, blocks, lots, and alleys, and specify the size of the same, with measurements and area of each municipal subdivision the lots in which shall not exceed 4,200 square feet, with a statement of the extent and general character of the improvements.  The plat and statement must be verified by the oath of the party, acting for and in behalf of the occupants and inhabitants of the town or city.  Within one month after filing the plat with the recorder of the county a verified copy of said plat and statement must be sent to the General Land Office, accompanied by the testimony of two witnesses that such town or city has been established in good faith, and a similar map and statement must be filed with the register and receiver of the proper district office.  Thereafter the President may cause the lots embraced within the limits of such city or town to be offered at public sale to the highest bidder, subject to a minimum of $10 for each lot; and such lots as may not be disposed of at public sale shall thereafter be liable to private entry at such minimum or at such reasonable increase or diminution thereafter as the Secretary of the Interior may order from time to time, after at least three months’ notice, in view of the increase or decrease in the value of the municipal property.  Any actual settler upon any lot and upon any additional lot upon which he may have substantial improvements shall be entitled to prove up and purchase the same as a preemption, at such minimum, at any time before the day fixed for the public sale. (See section 2382, U.S.  Revised Statutes.)

21.  In case the parties interested shall fail or refuse within twelve months after founding a city or town to file in the General Land Office a transcript map, with the statement and testimony, as required in paragraph 20, the Secretary of the Interior may cause a survey and plat to be made of said city or town, and thereafter the lots will be sold at an increase of 50 per cent on the minimum price of $10 per lot. (See section 2384, U.S.  Revised Statutes.)

22.  When lots vary in size from the limitation of 4,200 square feet and the lots, buildings, and improvements cover an area greater than 640 acres, such variance as to size of lots or excess in area will prove no bar to entry, but the price of the lots may be increased to such reasonable amount as the Secretary of the Interior may by rule establish. (See section 2385, U.S.  Revised Statutes.)

23.  Under the second method lands actually settled upon and occupied as a town site, and therefore not subject to entry under the homestead laws, may be entered as a town site at the proper district land office.  (See section 2387, U.S.  Revised Statutes.)
