This is a claim for $512,515.50, being the price of 20,500,620 pounds of copper at 26 cents a pound less payments received at 23 1/2 cents. The petition was dismissed by the Court of Claims on demurrer. The facts alleged are as follows. The Government had some correspondence with the United Metals Selling Company ending in an order or proposal for 30,000 metric tons of copper for the French Government to be delivered on or before June 1, 1918. To this the Company replied on March 26, 1918, that the Copper Producers Committee had divided the handling of copper and had given the export business to the American Smelting and Refining Company. The letter requested that the order be changed to apply to the last-named company and concluded 'they tell us that it will quite fit in with their operations to handle this present order along with the other shipments.' Thereupon, on March 28, 1918, a letter was written by the Ordnance Department to the American Smelting & Refining Company, 'to advise you that the Procurement Division is prepared to procure from you 30,000 metric tons (66,138,000 pounds) of copper at a price of 23 1/2 c. per pound net, f. o. b. New York basis. Deliveries are to be completed on or before June 1, 1918'; shipping instructions to be taken up with the Supply Division, Ordnance Department; with further particulars not material and ending, 'Your acceptance of this letter is requested pending issuance of formal contract which will go forward in a few days.' The representative of the claimant seems to have delayed an answer in the hope of adjusting one or two details but on April 11, wrote:

'We have your favor March 28th * * * and take pleasure in accepting your letter as above pending issuance of formal contract which we hope to receive in the near future.'

The copper except the 20,500,620 pounds, was delivered before July 2, 1918, has been paid for and no question is raised about it. But it was practically impossible to deliver this last amount until after that date and no shipping orders for it were received until a later time. It was delivered finally and the claim for the advanced price is based upon the facts and arguments that we shall state.

At the time when the order was accepted the Price-Fixing Committee of the War Industries Board, an agency of the Council of National Defence, had fixed the price of copper at 23 1/2 cents per pound f. o. b. New York, under the Act of August 29, 1916, c. 418, § 2, 39 Stat. 619, 649 (Comp. St. §§ 3115a-3115e), and the authority of the President. On July 2, 1918, the price was advanced to 26 cents per pound. The National Defence Act of June 3, 1916, c. 134, § 120, 39 Stat. 166, 213 (Comp. St. §§ 3115f-3115h), had author ized the President in time of war 'in addition to the present authorized methods of purchase or procurement, to place an order' for material required, made compliance with such orders obligatory under a penalty, and gave them precedence. The compensation paid was to be fair and just. The position of the claimant is that although the language of contract was used, it was yielding to the requirements of the statute and is entitled to the fair price that the statute promised. The fair price, it contends, for copper delivered after the change of July 2, is 26 cents, because the delay is alleged to have been due to the failure of the Government to send shipping orders and to the fact that further deliveries were made impossible for the time by the Government's appropriating all the copper available to other uses. It also argues that there was no valid contract, since the agreement was not made by advertising and was not within the exception when the public exigencies require immediate delivery. Rev. St. § 3709 (Comp. St. § 6832).

We may lay the latter objection on one side. There can be no question that the war created a public exigency and it would be going far to deny that the contract was for a delivery as immediate as was practicable for the subject-matter. Moreover the statutory requirements were for the protection of the United States, not to the seller. United States v. New York & Porto Rico Steamship Co., 239 U. S. 88, 36 Sup. Ct. 41, 60 L. Ed. 161. Of course the expressed contemplation of a more formal document did not prevent the letters from having the effect that otherwise they would have had. The only serious argument is the supposed duress. But that can not prevail. It may be true that the claimant was yielding to the statute in a general way and did not discriminate between what it was required to yield and what it could reserve. But if it had desired to stand upon its legal rights it should have saved the question of the price. It did not do so, but on the contrary so far as appears was willing to contract and was content in the main with what was offered. As was pointed out by the Court of Claims, the acceptance was sent because the claimant was advised by the Government that no payment could be made until the claimant had accepted in writing the Government's proposal, whereas no acceptance was necessary if the order was a compulsory requisition. We are of opinion that the claimant must stand upon the letters of March 28 and April 11.

The claimant argues that under its contract it was set free by the delay in shipping orders, and that although it did not refuse to proceed on that account, the omission should be credited to patriotism, not to a waiver of legal rights. But whatever the motives for its conduct the claimant kept the contract on foot. It even is said to have requested to be allowed to continue deliveries after June 1. Its claim if any must be for damages on the ground that the United States did not perform its part of the contract on time. Such a claim is not necessarily waived by completing performance. St. Louis Hay & Grain Co. v. United States, 191 U. S. 159, 164, 24 Sup. Ct. 47, 48 L. Ed. 130. But the petition is framed on the theory that there was no contract but a requisition under the above mentioned Act of June 3, 1916, c. 134, § 120, and that the claimant is entitled to just compensation by that section and by the Fifth Amendment to the Constitution. This we hold to be a mistake. Whether any claim for damages could be urged is not before us; the petition discloses grounds for doubt at least. Our judgment excludes any remedy under the Act of March 2, 1919, c. 94, 40 Stat. 1272 (Comp. St. Ann. Supp. 1919, §§ 3115 14/15a-3115 14/15e), providing for supplies and services furnished under agreements not executed in the manner prescribed by law. We have said nothing about repeated requests that the claimant should sign a formal contract, its refusals, and its ultimate signing under protest, because these facts in no way modify the relation of the parties under the contract by letters already made.

Judgment affirmed.
