delivered the opinion of the Court.
Thе United States, plaintiff below, and certain surety companies, defendants below, appeal from a decree of the Circuit Court of Appeals,
The controversy concerns the right of the banks, as against appellants, to set off against debts owing to them by the Butterworth-Judson Corporation the deposit balances remaining with them in special accounts.
The Butterworth-Judson Corporation, a' contractor, and the United States made an agreement, dated May 9, 1918. The contractor agreed to select a site and, for a profit of one dollar and no more, to design, construct and equip thereon a-plant for the production of picric acid, and to manufacture for the United States 72,000,000' pounds for 53 cents per pound. The entire cost of the plant was to be paid by the United Statesf The contractor. was to make all necessary expenditures for the construction work, and the United States from time to time was to reimburse it therefor. The United States agreed to recommend to the War Credits Broad an advance payment to the contractor of $1,500,000, upon such terms as the board might prescribe; and also agreed that, if the board should require interest on the advance payment, it would reimburse the contractor as a part of the cost and expense of thе latter under the contract. The United States reserved the right to cancel the agreement at any time that its need for the plant or - output ceased. It agreed in such event to reimburse the contractor for its expenditures, to assume all its outstanding obligations incurred under the contract, and to pay for all the picric acid wholly or partly manufactured; and it agreed, in case of cancelation before 18,000,000 pounds were delivered, to pay three cents per pound for the undelivered portion up.to that amount.
The same parties made a supplementary agreement, dated May 22, 1918. The United States agreed to advance $1,500,000 to the contractor. The contractor agreed to account for the advance with interest, by applying that *390 amount to the payment of vouchers covering deliveries of picric acid. The contractor reserved the right at any time to repay in cash; If the United States did not recoup, through the deliveries of picric acid, the total amount of the advance with interest, the contractor was required to “ return to the Govеrnment, on demand, any balance of the said advance and interest after deducting the total of any recoupments made as hereinabove provided, together with all liquidated accounts that may be due and owing under the Principal Agreement from the Government to the contractor.” The contractor agreed to give the United States, as collateral security for the recoupment or return of the above mentioned advance and any interest due, its demand note for $1,500,000, bearing six per cent, interest, and to furnish a bond in the sum of $750,000, with surety, fpr the performance of the agreement. The United States reserved the right,, in case of failure of the contractor to comply with the agreement, to sell, the note and apply the proceeds .to the repayment of the advance, accounting to the cоntractor for the surplus, if any. But it agreed not to negotiate or demand payment of the note, so long as the contractor was not in default, and to return the note and bond upon complete performance. • And the agreement contained the following: “ The contractor shall deposit the money advanced hereunder in special accounts in banks, separate from its other funds, and shall draw on said accounts only in payment of expenditures made and obligations incurred in designing, constructing and equipping the plant specified in the Principal Agreement, and for other equipment and for material, labor and overhead expense, required in the .direct performance of the Principal Agreement, unless otherwise i authorized in writing by the War Credits Board.” It was stipulated that the contracting officer might require the contractor to deposit in the special accounts the funds paid by the Government, reimbursing *391 the contractor for expenditures made from such advance payment. The contractor was to collect from the banks with which such accounts were kept such interest as is usually allowed for similar accounts, and credit or pay that interest to the Government.
The bonds provided for in the principal and supplementary agreements were furnished. The United States advanced $1,500,000 to the contractor, and the latter gave its note as agreed. The contractor deposited the monej with defendant banks in special accounts, and entered upon the performance of the agreement. It made with-. drawals from these accounts for' the specified purposes, and from time to time deposited therein the sums paid to it by the United States in reimbursement of its expenditures. The banks at all times knew that the moneys deposited by the contractor in the special accounts consisted exclusively of 'the advance payment and replenishments, and that all deposits and balances in these accounts were held pursuant to the principal and supplementary agreements. Shortly after the Armistice, the plant being less than half completed, the United States terminated the principal agreement. No picric acid had been manufactured. The United States reimbursed the contractor and assumed all the latter’s obligations under the principal agreement. It was shown in a creditors’ suit in the District Court that the contractor was unable to pay its debts, and April 22, 1922, the. court appointed receivers who are defendants in this case. Neither the contractor nor its receivers accounted' to the United States for any part of the advance of $1,500,000 or interest, except $348,-550, leaving unaccounted for, as the United States claims, $1,151,450. The total of the balances in the special accounts on April 22, 1922, was $519,631.99. On that day, the contractor was indebted to each of the banks in an amount in excess of the balance in the special account with it, and each bank set off the amount of such deposit against the debt owed by the contractor.
*392 The suit was'for an accounting and to have the balances in the special accounts applied on the amount found unaccounted' for and due the United States on the settlement of the account between it and the contractor. In affirming the District Court, the Circuit Court of Appeals held that the advanсe payment was for supplies purchased and thereafter to be delivered, and that the Secretary of War had no authority to retain title to the moneys advanced and make the contractor agent of the United States for its disbursement; that the supplementary' agreement created no relation of trust or agency between the parties, but. only that of debtor and creditor.' It held that the doctrine of trust, or equitable lien, or equitable assignment, did not apply, and that the banks had'the right of set-off. The appellants maintain that the United States hаd an equitable lien on the balances in the special accounts, and that the banks, having notice of the lien, could not set off the deposits against the debts owed them by the contractor.
The advance payment was made under the authority of an.act of Congress of October 6, 1917, § 5, c. 79, 40 Stat. 383, which provides: “ That the Secretary-of War and the Secretary of the Navy are authorized, during the period of the. existing emergency, from appropriations available therefor to advance payments to contractors for supplies fоr,their respective departments in amounts not exceeding thirty per centum' of the contract, price of such supplies:
Provided,
That such advances shall be made upon such terms as the Secretary of War and the Secretary of the Navy, respectively, shall prescribе and they shall require adequate security for the protection of the Government for the payments so made.” The act was intended to relax, during the period of the war, the strict rule against advances of public money. See R. S. § 3648.
The Floyd Acceptances,
The agreemеnts made the balances in the special accounts security for the obligations of the contractor and so created -an equitable lien in favor of the United States.
The established rule as to the creation of equitable liens is stated in
Walker
v.
Brown,
Ordinarily, the relation existing between banks and' their depositors is that of debtor and creditor, out of which the right оf set-off arises. As a general rule, in the
*395
absence of an agreement to the contrary, a deposit, not made specifically applicable to some other purpose, may be applied by the bank in payment of the indebtedness. of the depositor. See
