BREITENSTEIN, Circuit Judge. Appellants-plaintiffs Choctaw Nation and Chickasaw Nation, two Indian tribes, brought suit to secure possession of, quiet title to, and recover a reasonable rental for a tract of about 200 acres formerly reserved from allotment because of an easement acquired by a predecessor of the appellee, The Atchison, Topeka and Santa Fe Railway Company. The district court sustained a motion to dismiss and this appeal followed.
