assessment and sale, the supreme-court of Minnesota had held other portions of the same grant, under identical conditions, to be taxable. Cass Co. v. Morrison, 28 Minn. 257, 9 N. W. Rep. 761. After the sale of the lands to plaintiff, the supreme court of the United States, in deciding the appeal from the supreme court of the Territory of Dakota, held the lands not taxable. Railroad Co. v.
