About one-third of the Indians have become landless with the exception of their 80 acre homestead which could not be alienated by an act of Congress. Many of these lands are valuable oil lands, one tract in particular consisting of 280 acres produced $3,000,000 in oil in the past 10 years, this allotment was mortgaged by the Indian for $2,000 and lost by reason of foreclosure. We have known of the Milk River anticline and conceded by Government geologists as one of the most promising oil structures on the Blackfeet Indian Reservation. You will note that looking at plats of the reservation that nearly all of the lands lying therein are patented. Louis Hill of the Great Northern Railway Co. who was at that time one of the major lessees through his lobbyists in Washington was able to get that area of land patented in fee. We are asking to hold our lands in trust and non-assessable.”

In 1944 Judge Charles N. Pray ruled that the 1887 Indian Allotment Act reserved all of the minerals underlying the Blackfeet Reservation, but none of the oil & gas minerals were returned to the Blackfeet Indians. The defendants in U.S. v. C.E. Frisbee were the Texas Co. [Texaco] and J.L. Sherburne, the agency trader. The fee minerals [white owned] on the reservation have grown to 28% of the reservation minerals, while the oil companies directed J.L. Sherburne and C.E. Frisbee to the productive oil properties on the Blackfeet Indian Reservation and the agency superintendent issued fee patents to the illiterate Indian owners as part of the larger conspiracy to defraud the Indians. State and corporate political and economic apartheid is built on the backs of the poor and exploitation of the resources of a nation and people.
