Thus the event which the regulations and the lease declare shall terminate the supervision by the Secretary of the Interior of the collection, care and disbursement of the royalties has not occurred. Nor has the occasion for some supervision disappeared. The heir is a full-blood Indian, as was the allottee, and is regarded by the act as in need of protection, as was the allottee. In the absence of some provision to the contrary the supervision naturally falls to the Secretary of the Interior. ”

Conveyances without its approval fall within the ban of the restrictions. That the agency which is to approve or not is a state court is not material. ”
