“ Of course, the purpose in requiring any approval is to safeguard the interests of the full-blood Indian heir. Where he is a minor he can convey only through a guardian, and no court is in a better situation to appreciate and safeguard his interests than the one wherein the guardianship is pending. Besides, as a general rule, a guardianship carries with it exclusive power to direct the guardian and to supervise the management and disposal of the ward's property. ”

“ Section 22 read as follows:
'That the adult heirs of any deceased Indian of either of the Five Civilized Tribes whose selection has been made, or to whom a deed or patent has been issued for his or her share of the land of the tribe to which he or she belongs or belonged, may sell and convey the lands inherited from such decedent; and if there be both adult and minor heirs of such decedent, then such minors may join in a sale of such lands by a guardian duly appointed by the proper United States court for the Indian Territory. ”

“ One ground on which the guardian's sale on behalf of the minor heirs, Amos and Elizabeth, is assailed is that it was in violation of this proviso. But in our opinion the proviso does not include or affect inherited lands. It refers, as a survey of the act shows, to lands of living minor allottees and not to lands inherited from deceased allottees. Section 9 expressly recognizes that the latter may be sold, and this proviso cannot be taken as prescribing the contrary. The word 'living' evidently is intended to mark the distinction. ”
