1
This is an appeal from a judgment of the Court of Claims which dismissed the petition on demurrer. The plaintiff owns a shortline railroad which it operated, but which is alleged to have been under federal control from January 1 to July 1, 1918. The suit was brought to recover, for that period, amounts representing the deficit in operating income, under maintenance of way and equipment charges, and the rental value of the property, which are claimed under section 3 of the Federal Control Act, March 21, 1918, c. 25, 40 Stat. 451, 454 (Comp. St. 1918, Comp. St. Ann. Supp. 1919, § 3115 3/4 c). There was annexed to the petition as an exhibit the copy of a contract between the plaintiff and the Director General of Railroads, dated February 26, 1919. It deals, in the main, with the mutual relations of the parties for the period after July 1, 1918, but section 3 of the contract provides as follows:


2
'The company * * * expressly accepts the covenants and      obligations of the Director General in this agreement set out      and the rights arising thereunder in full adjustment,      settlement, satisfaction, and discharge of any and all claims      and rights at law or in equity, which it now has or hereafter      can have against the United States, the President, the      Director General or any agent or agency thereof by virtue of      anything done or omitted, pursuant to the acts of Congress      herein referred to.


3
'This is not intended to affect any claim said company may      have against the United States for carrying the mails or for      other services rendered not pertaining to or based upon the      Federal Control Act.'


4
The acts of Congress referred to in the contract were the Federal Control Act, the Act of August 29, 1916, c. 418, 39 Stat. 619, 645 (Comp. St. § 1974a), and the Joint Resolutions of April 6, 1917, and December 7, 1917, 40 Stat. 1, 429. The government assigned as a ground of demurrer that the copy of the contract annexed to the petition showed that the claims sued on had been settled and that the United States had been released from any liability to the plaintiff.


5
The petition alleges, among other things, 'that section 3 thereof does not contain and was not intended to contain any receipt or acknowledgement of any consideration by or in favor of the plaintiff for the use of said railroad property during said six months from January 1 to July 1, 1918;' that the section refers only to other provisions; and that the 'plaintiff gained nothing by the execution of this contract, and by it no rights were lost.' The contention is that these allegations are admitted by the demurrer; and that for this and other reasons section 3 cannot properly be construed to apply to claims of the character of those sought to be recovered, because these 'did not arise out of the contract or because of anything contained in it.' The allegations in the petition as to the meaning, application and effect of section 3, being conclusions of law, are not admitted by the demurrer. United States v. Ames, 99 U. S. 35, 45, 25 L. Ed. 295; Chicot County v. Sherwood, 148 U. S. 529, 536, 13 S. Ct. 695, 37 L. Ed. 546; Equitable Life Assurance Society v. Brown, 213 U. S. 25, 43, 29 S. Ct. 404, 53 L. Ed. 682. The legal effect of the instrument remains that which its language imports. Inter-State Land Co. v. Maxwell Land Grant Co., 139 U. S. 569, 578, 11 S. Ct. 656, 35 L. Ed. 278. The contract here in question appears to have been carefully drawn. It is the standard form short-line or co-operative contract said to have been executed by more than a hundred railroads.1 The language employed in section 3 to embody the agreement for settlement and release of claims is so clear and comprehensive as to leave on its face no room for construction. United States v. Wm. Cramp & Sons Co., 206 U. S. 118, 128, 27 S. Ct. 676, 51 L. Ed. 983. And we do not find in any other part of the contract any provision which prevents the application of the release clause to the claims here in suit.


6
There is no contention that the contract as written does not express the actual agreement, nor a prayer that, because of mutual mistake, it should be reformed. The petition contains allegations which indicate that originally it was intended to challenge the validity of the contract because of duress, lack of consideration, and want of power in the Director General to enter into the same. But the plaintiff's brief declares that the sole question before the court is whether section 3 of the contract is a settlement or waiver of the claim in suit. And more specifically:


7
'It is not alleged nor now claimed that the contract was      wholly and absolutely void because of total lack of      consideration, or because the same was executed under      forceable and legal duress.'


8
Any claim based on a lack of authority in the Director General is clearly unfounded.


9
There is in the brief a suggestion that the lower court erred in giving effect to section 3 because 'the contract was set out as an exhibit to the petition not as a part thereof, but merely for the purpose of showing to the court that the cause of action set out in the petition * * * [was] entirely independent of and arose outside of the contract itself.' The suggestion is unsubstantial. Ordinarily, the defense of release or accord and satisfaction must be pleaded in bar. But where the fact appears either in the body of the petition, or from an exhibit annexed, the defense may be availed of on demurrer. Compare Randall v. Howard, 2 Black, 585, 589, 17 L. Ed. 269; McClure v. Township of Oxford, 94 U. S. 429, 433, 24 L. Ed. 129; Speidel v. Henrici, 120 U. S. 377, 387, 7 S. Ct. 610, 30 L. Ed. 718.


10
Affirmed.
