delivered the opinion of the court.
This claim, as construed by the claimant and appellant is based upon covenants supposed to be imported by an act of Congress of July 25, 1866, c. 241, § 9. 14 Stat. 236. Upon demurrer it was dismissed by the Court of Claims. 47 C. Cl. 59. The largeness of the demand tends to induce a correspondingly voluminous statement, but the issue really is narrow and the material facts are few.
The United States had made land grants to the great roads running east and west but had not provided for a connection between those roads and the Gulf, through Kansas and the Indian Territory to the south. To that end, the act of July 25, 1866, after granting to Kansas, for the use of a road to be built through eastern Kansas from the eastern terminus of the Union Pacific between Kansas and Missouri, ten alternate sections per mile on each side of the road, § 1, authorized the company mentioned to extend its road from the southern boundary of Kansas south, through the Indian Territory to Red River, at or near Preston, in Texas, so as to connect with a road then being constructed from Galveston to that point. Section 8. The appellant also had been authorized by charter to build a road running southerly from a point on the Union Pacific to where the southern boundary of Kansas crosses the Neosho River, and had acquired a land grant; and the act of July 25, 1866,went on to provide that if the appellant, under its former name of Union *39Pacific Railway, Southern Branch, first completed its road to the point of crossing the southern boundary of Kansas, it should be authorized to construct its line to the point near Preston, “with grants of land according to the provisions of this act.” The right of way was granted in accordance with treaties with the Indians and is not in question here.
The appellant finished its road first, built the southern extension and acquired the rights to land under the act of 1866, and the question is what rights it has, in the event that has happened, under § 9. That section enacted “That the same grants of lands through said Indian Territory are hereby made as provided in the first section of this act, whenever the Indian title shall be extinguished by treaty or otherwise, not to exceed the ratio per mile granted in the first section of this act; Provided, That said lands become a part of the public lands of the United States.” This part of the Indian Territory was occupied by the five civilized tribes, and what has happened is that under acts of Congress the land concerned has been distributed in severalty to the members of those tribes or sold for their benefit.
Taken literally the grant or covenant of the United States was subject to two conditions precedent. ‘Whenever the Indian title shall be extinguished’ means when and not until that occurs, and contemplates it as something that may or may not come to pass. The proviso attaches the further condition that if the Indian title shall be extinguished it must be extinguished in such a way that the lands become a part of the public domain. It cannot be said that ‘whenever’ imports that sooner or later the Indian title will and shall be disposed of. The Indians had to be considered and it could not be assumed that they would be removed to another place, as they had been removed before. It cannot be said, either, that on the face of the clause the proviso adds nothing and means *40only that on extinction of the Indian title the rights of the railroad shall attach as if the land were public land. The section taken by itself and on its face excludes the claimant’s interpretation that the United States made an absolute promise or grant, and it excludes it none the less that certain services were to be rendered by the road to the United States as one of the terms of the grant of a fight of way which the railroad got. — On this literal reading of the statute the conditions have not been fulfilled. The land has remained continuously appropriated to the use. of thé Indians or has been sold for their benefit. It never for a moment has become a part of the public domain in the ordinary sense. Newhall v. Sanger, 92 U. S. 761, 763. Union Pacific R. R. Co. v. Harris, 215 U. S. 386, 388. It is argued that the grant attached the moment that the tribal title ceased, whatever it was. But, still looking only at the face of the act and seeing the in-' tent to respect the Indian rights, we cannot read it as preventing the United States from making the change from tribal to several possession or dealing with -this land in any way deemed most beneficial for those whose rights were treated as paramount. The proviso that the land must become public land shows that a mere change from tribal title was not enough. Taken literally the grant only applied in case the Indians were removed or bought off the land.
The facts existing at the time confirm the literal interpretation of the act. Less than a week before the passage of the statute the United States had made a treaty with the Cherokees that contemplated the possible allotment of their share in this land to be held in severalty. Treaty of July 19, 1866, Art. 16, 14 Stat. 799, 804. On June 14, 1866, it had agreed with the Creeks that their lands should be forever set apart as a home for the Nation. 14 Stat. 785. And by a treaty of April 28, 1866, Art. 11, it had agreed with the Choctaws and Chickasaws that *41they might have their lands surveyed and divided up, reciting that it was believed that the holding of the land in severalty would promote the general civilization of said Nation. 14 Stat. 769, 774. Whether or not, as the Government contends, the title of these tribes to the land in controversy was higher than the original possessory right, the United States, as the appellant must be taken to have known, just before its covenant with the railroad, had been holding out to the Indians the desirableness and possibility of dividing up their lands into individual holdings; and it would be to accuse the Government of bad faith to one party or the other to suggest that it forthwith agreed with the appellant that the moment such a division and allotment took place the appellant thereby should acquire a paramount title and render the allotment vain. See further Kansas v. United States, 204 U. S. 331, 341, 342.
The action of Congress in making the allotment to individuals shows in express terms that it did not suppose that the railroads would, or intend that they should, acquire any new rights. Act of March 1, 1901, c. 676, § 23; 31 Stat. 861, 867. July 1, 1902, c. 1362; 32 Stat. 641. July 1, 1902, c. 1375; 32 Stat. 716. April 26, 1906, c. 1876, § 27; 34 Stat. 137, 148. Our conclusion from the words of the statute and the circumstances seems to us too plain to require a reference to the rule of strict construction against the grantee of the Government in case of doubt, and seems to us unaffected by the argument that a grant in prcesenti was made by § 9. It appears to us that the appellant’s claim stands most strongly if based upon a covenant — but, covenant or grant, the concession of the United States w,as dependent upon conditions that have not been fulfilled.
Judgment affirmed.
