UNITED STATES
v.
STATE BANK.
Supreme Court of United States.

*31 The Solicitor-General, for the United States.
Mr. C.B. Goodrich, for the State Bank.
Mr. Sidney Bartlett, for the banks.
*33 MR. JUSTICE SWAYNE delivered the opinion of the court.
Upon analyzing this case as it is presented in the record, the facts are found to be few and simple.
Hartwell was cashier of the sub-treasury in Boston. He embezzled a large amount of money belonging to the United States, by lending it to Mellen, Ward, & Co. As the time for the examination of the funds in the sub-treasury approached, Mellen, Ward, & Co. endeavored to tide Hartwell over the crisis, and to conceal his guilt and their own by the devices out of which this controversy has arisen. They had sold to the Merchants' National Bank, of Boston, a large amount of gold certificates, with the understanding that they might buy back the like amount by paying what the bank had paid, and interest at the rate of six per cent per annum. Carter, one of the firm, arranged with Smith, the cashier of the State National Bank, of Boston, to buy from the Merchants' National Bank, of Boston, gold certificates to the amount of $420,000, and to pay for them with the checks of Mellen, Ward, & Co., certified to be good by Smith as such cashier, and then to deposit the certificates in the sub-treasury, where they were to remain until the ensuing day. A receipt was to be taken from the proper sub-treasury officer. The certificates were bought, paid for, and deposited accordingly. Hartwell received them from Smith in the presence of Carter, and made out the receipt to Mellen, Ward, & Co., or order. Smith inquired why the receipt was to them. Carter thereupon indorsed it by the firm name to Smith as cashier, and Smith took it without further remark.
Subsequently, pursuant to a like arrangement between the same parties, Smith, as such cashier, made a further purchase of gold and gold certificates from the Merchants' Bank, and converted the gold into gold certificates. The aggregate of the *34 certificates thus procured was $60,000. Thereafter Smith, as such cashier, at the instance of Carter, made a further purchase of gold certificates from another bank to the amount of $100,000. All these certificates, amounting to $160,000, were also deposited by Smith in the sub-treasury in the presence of Carter, and a receipt taken and indorsed as before to Smith as cashier. The receipts specified that the certificates deposited were "to be exchanged for gold certificates or its equivalent, on demand" Only $60,000 of the last deposit is claimed by the appellee. The residue is not involved in this controversy. The total claimed is $480,000. All these things occurred on the 28th of February, 1867. On the following day, Smith presented the receipts at the sub-treasury, and payment was refused. The certificates were all cancelled, and sent to the proper officer at Washington. The gold which they represented has since remained in the treasury of the United States. Carter gave Smith plausible reasons, not necessary to be repeated, for desiring to make the deposits. The Court of Claims found these facts: "He (Carter) submitted his plan to Hartwell, which was as follows: He proposed to buy gold certificates in New York, bring them to Boston, and borrow money upon them of the Merchants' Bank, and he then proposed to get Smith, the cashier of the State Bank, to pay for these certificates, and leave them with Hartwell during the examination. Hartwell made no objection to this plan, but he thought Smith would not do it. The plan was carried into effect by Carter, as hereinbefore set forth; but Hartwell had no agency in carrying it out, except to receive the moneys and gold certificates paid to him on the 28th of February, as aforesaid, and he had no actual knowledge of the proceedings taken by Carter on that day to obtain said gold certificates. When Carter and Smith deposited the $420,000 of gold certificates in the sub-treasury, as aforesaid, Smith did not know Hartwell, nor did Hartwell know Smith, or know that Smith was connected with any bank or money institution."
The case, under another aspect, was before us on a former occasion. Merchants' Bank v. State Bank, 10 Wall. 604. We there held, after the most careful consideration, that the legal title to the certificates was, by the purchases made by its cashier, *35 vested in the State Bank. We find no reason to change this view. The finding of the court shows clearly that Hartwell knew when he received the certificates that they did not belong to Mellen, Ward, & Co., and that they did belong to the State Bank, represented by Smith as its agent. Hartwell was privy to the entire fraud from the beginning to the end, and was a participant in its consummation.
It is not denied that Smith acted in entire good faith. What he did was honestly done, and it was according to the settled and usual course of business. Hartwell was the agent of the United States. He was appointed by them, and acted for them. He did, so far as Smith knew, only what it was his duty to do, and what he did constantly for others, and it is not denied that it was according to the law of the land. 12 Stat. 711. Smith no more suspected fraud, and had no more reason to suspect it, than any other of the countless parties who dealt with the sub-treasury in like manner.
There could hardly be a stronger equity than that in favor of the plaintiff. It remains to consider the law of the case.
The interposition of equity is not necessary where a trust fund is perverted. The cestui que trust can follow it at law as far as it can be traced. May v. Le Claire, 11 Wall. 217; Taylor et al. v. Plumer, 3 Mau. & Sel. 562.
Where a draft was remitted by a collecting agent to a sub-agent for collection, and the proceeds were applied by the sub-agent in payment of the indebtedness of the agent to himself, in ignorance of the rights of the principal, this court held that, there being no new advance made, and no new credit given by the sub-agent, the principal was entitled to recover against him. Wilson & Co. v. Smith, 3 How. 763. See also Bank of the Metropolis v. The New England Bank, 6 id. 212.
A party who, without right and with guilty knowledge, obtains money of the United States from a disbursing officer, becomes indebted to the United States, and they may recover the amount. An action will lie whenever the defendant has received money which is the property of the plaintiff, and which the defendant is obliged by natural justice and equity to refund. The form of the indebtedness or the mode in which it was incurred is immaterial. Bayne et al., Trustees, v. United States 93 U.S. 642.
*36 The United States must use due diligence to charge the indorsers of a bill of exchange, and they are liable to damages if they allow one which they have accepted to go to protest. United States v. Barker, 12 Wheat. 560; Bank of the United States v. The United States, 2 How. 711; The United States v. Bank of the Metropolis, 15 Pet. 377.
In these cases, and many others that might be cited, the rules of law applicable to individuals were applied to the United States. Here the basis of the liability insisted upon is an implied contract by which they might well become bound in virtue of their corporate character. Their sovereignty is in no wise involved.
Atlantic Bank v. The Merchants' Bank (10 Gray (Mass.), 532) and Skinner v. The Merchants' Bank (4 Allen (Mass.), 290) are, in their facts, strikingly like the case before us, and they involved exactly the same point. It was held in each of those cases, after an elaborate examination of the subject, that the defrauded bank was entitled to recover.
But surely it ought to require neither argument nor authority to support the proposition, that, where the money or property of an innocent person has gone into the coffers of the nation by means of a fraud to which its agent was a party, such money or property cannot be held by the United States against the claim of the wronged and injured party.
The agent was agent for no such purpose. His doings were vitiated by the underlying dishonesty, and could confer no rights upon his principal.
The appellee recovered below the amount claimed. A different result here would be a reproach to our jurisprudence.
Judgment affirmed.
NOTE.  In Merchants' Bank v. United States, MR. JUSTICE SWAYNE, in delivering the opinion of the court, remarked, the opinion in United States v. State Bank (supra, p. 30) decides this case. Judgment affirmed.
