Mr. Justice Trimble

delivered the opinion of the Court

*506 The questions to be decided in this case arise out of a bill of exceptions, taken by the plaintiffs, to the charge and instructions of the Circuit Court to the jury upon the trial of ,the cause. a

The suit was founded on the official bond of Robert Swartwoul, ás-navj agent, and with whom the defendant had become bound as'one of his sureties. ■ The bond bears date the 22d day of February, 1819; aid is in the penalty of 20,000 dollars, with the usual condition, to be void if Swartwout should faithfully perform the duties of his office, and account for, and pay over, when required, the public property and money placed in his hands.

The declaration alleges, as a breach of the condition* of the bond, thatSwartwout’s accounts had been settled by the proper accounting officers on the day of and that, upon that settlement, a large balance had been found against him, which he had'failed and'refused to pay over to the United States when, required. The pleadings having .been made up according to the practice of Newr York, so as to put in issue the matters in controversy between the parties, the plaintiffs gave in evidence to the jury the bond, witii its condition, and Swarlwout’s settled account, duly certified from the treasury department; and the defendant gave in evidence a letter from the Secretary of the Navy tó Robert Swarlwout, dated the 25th day of February, 1819; two commissions to Swartwout as-uavy agent, the one dated the 16th day of October,18l8, and the other the 30th day of November, 1818, and the following letter, dated the 8th day of December, 1823, from Mr. Pleasanton, agent of the treasury, to Mr. Tillotson, the district attorney, which will be more particularlv noticed hereafter:

“ Sjr: From the best information I cat. obtain, it seems pretty certain that if we foreclose the mortgage given to'thc United States by General Robert Swartwout, and expose *507 the property to sale, subject to a previous mortgage given to Mr. Coster? we shall lose the whole, or nearly all of our debt; this property being our only reliance, if the sureties should be discharged by due course, of law from their responsibility for the payment of it. Under these .circumstances, the only alternative which presents its jlf for securing any considerable portion of the debt is, to allow General Swartwout time within which to make an advantageous disposition of the property. He expresses a confident belief ihat,rin seven years he would be enabled, by connecting it with a banking institution for which a charter has already been granted by the State of New-Jersey, not only to pay off the.first mortgage, but our mortgage also.,

“ It has been recommended by the Navy Department to allow this time, and 1 have, accordingly, instead of three years,,as intimated to-you some time ago, determined to allow him seven years, provided the first mortgagee will pledge himself in writing, not to molest him for the same space of time; and provided-also, that the bank with which the property is to be connected, shall go into operation on or before the first of October next. Should the banking capital not be made up -by the time mentioned, and the bank fail to go into operation, this agreement is to be considered wholly null and void. You will be pleased to take such steps as will give this arrangement effect.

“ As the sureties on General Swartwout’s bond dispute our right to recover the penalty from, them, it will be your duty forthwith to institute suits against them in the Circuit Court, and judgment going against us there, you - will remove the cause to the Supreme Court, it being very de-. sirable that the law should be settled in relation to bonds so situated.

The Circuit Court decided, and, accordingly, instructed the jury, first, “ That the defendant, Francis H. Nicóll, was not responsible for any defalcation that took place on the part of Robert Swartwout, as navy agent, subsequent to the *508 30th day of September, 1820, when, in and by the act of Congress, passed the ,18th of May, 1820, new sureties were required by law to be given by the said Robert Swartwout. • Secondly, “That the defendant was not responsible for any deficiency of public money reported on by the account.ofiicers of the United States, subsequent to the 30th of November, 1822, when it appeared in evidence that the appointment of Robert Swartwout, as navy agent, expired by its legal termination.

Thirdly,That he. left it to them to decide whether the letter from S. Pleasanton, .Esq. addressed to Robert Tillotson, Esq. which had been read in evidence before the jury, did give further time to Robert Swartwout for the payment of the debt due the United States; and that if,, in the opinion of the jury, the letter in question did give time to the said. Robért Swartwout until Octor ber, 1.824, or any subsequent period, that then the defendant was discharged from his liability, and their verdict' should be rendered for the defendant. And, lastly, that the said several matters so produced and read in evidence, on the part of the said Francis H. jNicoll, were sufficient, in laWj to maintain the issue on his part, and that the United States ought not, upon all the matters produced in evidence, to maintain the said acfion,” &c.

These several opinions and instructions, are brought before this Court for re-examination by the present writ of error.

Upon looking into the act of Congress, passed May 15th, 1820, entitled “An act providing for the better organiza^on c^e treasury department,” which is the one referred to in the first instruction, w.e are satisfied it was misconstrued by the judge. The second section of the act provides a new and summary process against public defaulter^ and their sureties, after the 30th of September, 1820. The scope, and design of the act, in requiring new sureties to be given by that day, was in order that, if such new sureties should he given, the summary process might operate upon them, as well as upon the principal, if the treasury department should elect to pursue such summary process. This is manifest from the provision in the act, that the summary process shall not affect the "existing sureties. ’

*509 Second in °

The act bo where directs the principals to be discharged from office^ upon failure to give new sureties; and if the act had so directed, they would have remained in office until actually removed. The law does pot, in terms, declare the existing sureties shall be discharged from and after the 30th of September, 1820. It would require a very strained construction of the statute to discharge them by implication, while their principals were permitted to remain in office. Such construction would be, we think, against the manifest intention of the legislature. The 10th section enacts, “that nothing in this act contained shall be construed to take away or impair any right or rerrred) which the United States now have, by law, for the recovery of taxes, debts, or demands.”

' The cases of the United States v. Kirkpatrick, (9 Wheat. Rep. 720.) and the United States v. Vanzandt. (11 Wheat. Rep. 184.) are, in principle, undistinguishable from this case.

They decide, 1st. That laches is not imputable to the government; 2d. that the provisions of the law requiring settlements by its officers to be made at short periods, are designed for the security and .protection of the government, and to regulate the conduct of those officers ; that they, arc merely directory to those officers, and form no part of the contract with the.sureties. And the last case decides, 3dly. That’where the act expressly directs a defaulting officer to be recalled at thi expiration of six months from the time of his default, his sureties are not discharged, but' remain liable for his defaults thereafter, until he is actually recalled.

If the second.instruction given to the jury was intended to inform them that the defendant, as surety of Swartwout, was not. legaih responsible for money placed by the government in his hands, after the legal termination of his office, it was unquestionably.correct; and this is the sense in which we suppose the Court méant to be under stood. But if it was intended,to convey the idea, that he was not responsible for money which came to Swartwout's hands while in office, but which he afterwards failed to at count for and pay over, it was clearly incotrécí.

*510 Third instruction.'

effect and operation of Mr. Pleasanton’s letter to the Dis-what would be the opinion of this Court, if it had appeared from the letter, that the government had made any arrangéhad been suspended to the first day of'October, 1824, or to any subsequent time. Nothing of the kind appears from the letter. It speaks of a mortgage which had been given by Swartwout, upon property subject to a former mortgage to Mr; Coster; but it does not appear that, by the terms of the mortgage, the right to sue on the official bond was suspended ; and the taking of a collateral security, without suspending the right to sue on the bond, could not bar the action on ' the bond. The letter speaks of an intention formed of giving time upon the mortgage, upon specified conditions ar.d contingencies ; but none of those conditions or contingencies are shown to have been complied with, or to have happened. The letter contains no contract, and gives no time per se, upon any consideration binding on the government; and that the letter did not intend tosuspend the right of the United States to sue on this bond, is palpable, because it directs suit to be brought thereon immediately. As no fact, connected with the létter, was proved by evidence aliunde, the construction of the letter upon its face was matter of law, and the- Circuit Court ought to have decided and instructed the jury accordingly, that nothing on the face of the letter constituted any defence to the action. There was nothing but the construction of the letter to be left to the jury, and the Court ought to have informed the jury that, according to its true construction, it did not give time so as to bar the action against the surety. ment with Swartwout, without the assent of his sureties, whereby the right of the .government to sue upon the bond

After the observations already made, it cannot be necessary to go into any further reasoning to show that the Circuit erred in.its concluding instruction, that, upon the whole matter, the-law was for the defendant. It was a conclusion $rawnby that Court from the premises it had assumed in the former instruct-km given, and the error of.these premises *511 having been shown, the error of the conclusion necessarily follows.

Some observations were made by the defendant’s counsel in argument, as to the manner in which the debits and credits in SwartwoutV account had been adjusted by the accounting officers; and beseemed to suppose, that credits which ought to have been -applied towards the extinguishment or lessening of the debits, for money placed in his hands before the 20th of November, 1822, had been improperly applied to the transactions -of .Swartwout with the. government after (hat day.

The case of' The United States v. January & Patterson, {t Cranch's Rep. 572.) is in point to show, that, as to any disbursements of money after the 30th of November, 1822, for which Swartwout was entitled to credit, it was at the election of the government to apply them to either account. But there is no necessity for the application of-the principle to this case; for, upon looking into the account, we find that, after crediting Swartwout with all his disbursements up until the 3Qth of November, 1822, there remained, on that day, a balauce in his hands unaccounted for, much beyond'the penalty of the bond ; so -that no injustice is done to the surety in the manner of settling the account.
