“ In so far as it is applicable here, it does no more than to withdraw a particular class of allotments from the restrictions imposed by Congress, and to authorize the immediate issue of fee-simple patents for them. Although saying nothing on the point, it evidently intends that the administrative officers shall be satisfied in each instance before issuing the patent that the allotment belongs to the particular class; and so the patent when issued carries with it an implication that those officers found the allotment to be of that class. ”

“ The allotment was made under legislation providing that the United States would hold the land in trust for the period of twenty-five years, and at the expiration of that period would convey the same to the allottee or his heirs by patent in fee discharged of such trust and free of all charge or encumbrance, and also that if any conveyance should be made of the land, or if any contract should be made touching the same, before the expiration of the trust period, such conveyance or contract should be absolutely null and void. ”

“ Stat. 1913, § 4203, which provides that when an Indian allottee is given a patent in fee for his allotment he 'shall have the benefit of and be subject to all the laws, both civil and criminal, of the state.' Among the laws to which the allottee became subject, and to the benefit of which he became entitled, under this enactment, were those governing the transfer of real property, fixing the age of majority, and declaring the disability of minors. ”
