In the case of Anderson v. Brule County, 67 S.D. 308, 313, 292 N.W. 429, 431, the court says regarding this matter: "That these and similar provisions in other enabling acts and constitutions of the several states were inserted for the purpose of maintaining ample supreme powers on the part of the United States to permit it to fully respond to its legal and moral obligations to the Indians rather than for the purpose of withholding power from the states to exercise jurisdiction over the reservations, and that it was intended the states should exercise a limited jurisdiction over Indian reservations within their exterior boundaries
