It is contended by defendants in error that, whatever questions may be found in the case, the decision of the supreme court of Alabama was upon a question not of a federal character, and one broad enough to sustain the judgment, and, therefore, that this court has no jurisdiction, and should dismiss the case. Hale v. Akers, 132 U. S. 554, 10 Sup. Ct. Rep. 171; Hopkins v. McLure, 133 U. S. 380, 10 Sup. Ct. Rep. 407; Blount v. Walker, 134 U. S. 607, 10 Sup. Ct. Rep. 606; Machine Co. v. Skinner, 139 U. S. 293, 11 Sup. Ct. Rep. 528; Henderson Bridge Co. v. City of Henderson, 141 U. S. 679, 12 Sup. Ct. Rep. 114; Navigation Co. v. Reybold, 142 U. S. 636, 12 Sup. Ct. Rep. 290.

As the mortgage to the state was executed some months before the contracts with Bagley, the title held by the state of Alabama under the bankruptcy proceedings would prima facie be paramount to that acquired by Bagley. Wilson v. Boyce, 92 U. S. 320. To avoid this, it was contended that under the act of February 11, 1870, and the mortgage of March 2, 1870, the railroad company, the mortgagor, was given the right to sell these lands; and the question which was considered and determined by the supreme court of the state, and the vital question, was whether the act and mortgage gave such authority. The act of February, 1870, provided that 'the said Alabama and Chattanooga Railroad Company shall have the privilege and right of selling said lands or any part thereof in accordance with the acts of congress granting the same.' The mortgage contained the same provision. In respect to this, the supreme court of the state thus expressed itself: 'This reservation was incorporated in the mortgage, and its construction, as applied to the facts of the case, is the controlling question for us to decide. The power retained by the mortgagor was not an unlimited power to sell. It was a power to sell only in accordance with the terms and conditions of the act of congress making the grant, which, we have said in a former decision, was 'a law as well as a grant.' If these terms and conditions were followed, then the lien of the mortgage was by agreement to be released. If they were not followed as to the mode or time prescribed or otherwise, then the contract of the parties is that the lien of the mortgage is to remain unaffected. Compliance with the essential requirements of the act of congress became thus a condition precedent to the divestiture of title out of the state as mortgagee. This, we repeat, was the express contract between the parties. It is sufficiently shown in the former opinion in this case that the attempt to sell to Bagley was in direct violation of the terms of the law of congress, and therefore necessarily also in violation of the agreement of the parties to the mortgage, which was based on that law. Swann v. Miller, 82 Ala. 530, 1 South. Rep. 65. The lien of the mortgage for this reason remained undischarged. This we understand to be the natural and just construction of the mortgage agreement and of the act of the Alabama general assembly approved February, 1870, above cited.' Section 4 of the act of congress of June, 1856, is as follows:

'Sec. 4. And be it further enacted, that the lands hereby granted to said state shall be disposed of by said state only in manner following, that is to say: That a quantity of land, not exceeding one hundred and twenty sections for each of said roads, and included within a continuous length of twenty miles of each of said roads, may be sold, and when the governor of said state shall certify to the secretary of the interior that any twenty continuous miles of any of said roads is completed, then another quantity of land hereby granted, not to exceed one hundred and twenty sections for each of said roads, having twenty continuous miles completed as aforesaid, and included within a continuous length of twenty miles of each of such roads, may be sold; and so, from time to time, until said roads are completed; and if any of said roads is not completed within ten years, no further sale shall be made, and the lands unsold shall revert to the United States.'

These lands confessedly were not part of the first 120 sections, which the state might sell prior to the construction of any portion of the road, and there is no pretense that at the time of these contracts of Bagley's any certificate had been made by the governor of the state to the secretary of the interior, as provided in the act. The supreme court, in its first opinion, held that, under the act of 1870 and the reservation in the mortgage, the railroad company had absolutely no power to sell until the making of that certificate; and that any attempted sale made prior thereto was a nullity, not voidable, but absolutely void. Now, whether that was a correct construction or not of the act of 1870, and the reservation of the mortgage, is a purely local question, and involves nothing of a federal character. The question is not what rights passed to the state under the acts of congress, but what authority the railroad company had under the statute of the state. The construction of such a statute is a matter for the state court, and its determination thereof is binding on this court. The fact that the state statute and the mortgage refer to certain acts of congress as prescribing the rule and measure of the rights granted by the state does not make the determination of such rights a federal question. A state may prescribe the procedure in the federal courts as the rule of practice in its own tribunals; it may authorize the disposal of its own lands in accordance with the provisions for the sale of the public lands of the United States; and in such cases an examination may be necessary of the acts of congress, the rules of the federal courts, and the practices of the land department, and yet the questions for decision would not be of a federal character. The inquiry along federal lines is only incidental to a determination of the local question of what the state has required and prescribed. The matter decided is one of state rule and practice. The facts by which that state rule and practice are determined may be of a federal origin.

We see nothing in the cases of Railway Co. v. McGee, 115 U. S. 469, 6 Sup. Ct. Rep. 123, and Doe v. Larmore, 116 U. S. 198, 6 Sup. Ct. Rep. 365, conflicting with these views, or throwing any light on this question. These cases involved simply a consideration of the effect to be given to the later act of congress, in respect to the rights of the state in the lands, and held that the later act was not to be considered as a new and independent grant, but simply as an extension of time.

Our conclusion, therefore, is that, as the construction of the statute of 1870 and following mortgage presented no question of a federal nature,—as upon that construction the supreme court decided the case,—and an such question is sufficiently broad to sustain the judgment, the case must be dismissed, and it is so ordered.
