The lands of full-blooded members of any of the Five Civilized Tribes are made subject to the laws of the State of Oklahoma, providing for the partition of real estate. Any land allotted in such proceedings to a full-blood Indian, or conveyed to him upon his election to take the same at the appraisement, shall remain subject to all restrictions upon alienation and taxation obtaining prior to such partition. In case of a sale under any decree, or partition, the conveyance thereunder shall operate to relieve the land described of all restrictions of every character.
