True, under the terms of this bill the Indians seem to have a right to take the water from the white settlers, but the practical difficulties against doing this, in the light of what has just been said, are, in my opinion, too obvious to require extended comment. I am anxious to favor in every way the actual bona fide homesteaders of northern Montana, and I will gladly sign any bill which will thus favor them, provided, that it explicitly and unequivocally guarantees to the Indians their water rights-that is the right of each Indian to a sufficiency of water to make his allotment of real use to him. Subject to this guaranty, and also to, of course, to the certainty that the action of the Government will redound not to the benefit of one individual or corporation who wishes to exploit the water rights, but to the benefit of the actual settlers. I will gladly approve any bill which may be drawn to achieve the purposes of this bill without containing its defects.”

Senator Walsh was doubly defeated in his bill to sell the surplus lands of the Indians left over after allotment likely containing the Indians irrigated lands, oil fields, and coal mines by the provision that: “The Secretary of the Interior shall make allotments under existing laws to any living children of said Blackfeet tribe, who have not heretofore been allotted, so long as there remains any un-allotted lands.” The Blackfeet Indian Reservation was then totally allotted except for tribal reserves of grazing lands, timber reserves, and reservoir sites, and for agency, school, and government townships.
