Wyoming constitution
Article 18: public lands and donations
Section 1

The State of Wyoming hereby agrees to accept the grants of lands heretofore made, or that may hereafter be made by the United States to the state, for educational purposes, for public buildings and institutions and for other objects, and donations of money with the conditions and limitations that may be imposed by the act or acts of congress, making such grants or donations. Such lands shall be disposed of only at public auction to the highest responsible bidder, after having been duly appraised by the land commissioners, at not less than three-fourths the appraised value thereof, and for not less than $10 per acre; provided, that in the case of actual and bona fide settlement and improvement thereon at the time of the adoption of this constitution, such actual settler shall have the preference right to purchase the land whereon he may have settled, not exceeding 160 acres at a sum not less than the appraised value thereof, and in making such appraisement the value of improvements shall not be taken into consideration. If, at any time hereafter, the United States shall grant any arid lands in the state to the state, on the condition that the state reclaim and dispose of them to actual settlers, the legislature shall be authorized to accept such arid lands on such conditions, or other conditions, if the same are practicable and reasonable.
