Mr. Justice GRIER
delivered the opinion of the court.
It would contribute nothing to a clear apprehension of the merits of this case to enumerate the various bills, answers, cross-bills, &c., constituting the very voluminous and confused
mass of pleadings and documents spread upon our. paper books. .The pleadings have been consolidated, by agreement of the; parties.. We may, therefore, consider the case before us. as a bill by. John Innerarity, administrator óf the estate of John Forbes, deceased, against the trustees of the Appalachicola Land Company, for the foreclosure of a mortgage given .under. the following circumstances.
On the 4th of December, 1818, John Forbes, acting as. the executor of William Panton and Thomas Forbes, and as agent of their respective heirs, covenanted to sell to Colin Mitchell
“
two undivided thirds of a certain tract of land ceded-by the Creek Indians unto the house of trade of which said Forbes was the principal partner, lying upon and between the rivers Appalachicola and Appalachee, .and cpritaining about one million two hundred' thousand. acres, for the consideration of $ 66,666.66, to be paid in the following manner: — One fourth, or $ 16,666, on the 1st of May next, in the city of London, valuing the same at four shillings and six pence sterling 'each dollar; the remainder, or $ 50,000, in four equal yearly instalments, reckoning from the date,” &.c.
This agreement was made and executed in the island of Cuba, where John Forbes then .resided. Colin Mitchell purchased for himself, Camochan, and others, and. subsequently todk' the title in his own name, and continued to hold it till 1820,- when he transferred it to Octavius Mitchell, who held it as trustee for the company then or afterwards known as the Appalachicola Land Company. On the 9th of October, 1820, Octavius Mitchell executed á mortgage to John Forbes for the last two instalments of $ 12,500 each, due, by the agreement, on the 8th. of December, 1820, and the 8th of December, 1821; but further time appears , to have been given in the mortgage for these two payments,' as they are made payable on the 9th of March, 1821, and the 9th of March, 1822. This mortgage is on the undivided half of the land conveyed to Mitchell, and is the subject of the present suit
John Forbes, the mortgagee, died in Cuba, in May, 1822, having made a will arid appointed executors, who qualified and acted as such in that place, but never proved the will nor obtained letters testamentary in Florida.
John Innerarity first obtained letters of administration in Florida, on the' estate of John Forbes, on the 5th of July, 1836.
That there is a balance due and unpaid on this mortgage seems to be admitted; but the parties differ widely in their estimates of its amount. The Supbrior Court for the county of Escambia, where this case originated, adjudged thfe balance
due on the mortgage to be $ 50,159.6.0. On appeal to the Court of Errors of the territory, that court decreed the balance due to be $ 28,500. From that decree both parties have appealed. At present, we can notice only the exceptions taken by the mortgagors, whose appeal is now under consideration.
They have insisted on three several exceptions to the decree of the,Court of Appeals, which will be noticed in their order.
1. Because interest was allowed from the time the money secured by the mortgáge became payable, when it should have been allowed only from the time of filing the bill for foreclosure.
2. Because the court refused to allow a credit of
£
375, which John Forbes admitted should be deducted from the amount claimed.
■3. Because a payment of
$
13,357.73, made to Thomas M. Blount, was not allowed as a credit.
We shall consider these exceptions in their order, stating the facts of the case bearing on each of them so far as may be necessary to their elucidation.
I. As to the interest.
As the contract for the purchase of these lands, and the mortgage given to secure the balance of the purchase-money, were executed in the island of Cuba, the court below allowed the current and legal rate of interest of that place (five per cent.) from the time the respective payments became due.
It is a dictate of natural justice, and the law of every civilized country, that a man is bound in equity, not only to perform his engagements, but also to repair all the damages that accrue naturally from their breach. Hence, every nation, whether governed by the civil or common law, has established a certain common measure of reparation for the detention of money not paid according to contract, which is usually calculated at a certain and legal rate of interest. Every one who contracts to pay money on a certain day knows, that, if he fails to fulfil his contract, he must pay the established rate of interest as damages for his non-performance. Hence it may correctly be said, that such is thq implied contract of the parties. (See 2 Fonblanque, Eq. 423. 1 Domat, book 3, tit. 5.) The appellants themselyes seem to have been fully aware of the justice of this rule, as in all their communications with the mortgagees they have admitted their liability to pay interest, and in their bill, filed in 1837, to have satisfaction entered on the mortgage- (which makes a part of the record of this case), they offer “ to pay interest at five per cent, from the 8th of December, 1821.” This may not of itself be a sufficient rea
son for disallowing their present exception, if founded in jus? tice, but it affords a strong ■ presumption that it has no such-foundation.
The reasons alleged- in support of this exception are, first, that the mortgagors had not possession of the land, or at least received no profits from it, and that, in either case, by the civil law, the purchaser is not bound to pay interest. But we are of opinion that this objection is founded on a mistake both of the law and the fact. The mortgage was given more .than two years after the sale to the mortgagors and title executed.to them. A large portion of the purchase-money had been paid, and no objection made, that' the purchasers had not all the possession' of which the land, was capable.- Both parties knew that, although the Indians had ceded their title, they still continued a transient occupancy of the lands for hunting-grounds. They may have infested the lands, and- rendered it dangerous for the owner to occupy them in time of war; but their possession was not what the law would term adverse, not. being with claim of title. There was no covenant by the vendor to. expel or exterminate the Indians; the purchasers received such possession of the land as could be given them,
cum onere.
It ' was not expected that the Indians should attorn to them or pay them rent. The purchasers of over a million of acres of wild lands did pot expect to make profits by actual cultivation or reception of rents. Their expectation of profit was from the-increase in value of the lands from efflux of time and the progress of improvement. These profits they have realized, doubtless to the amount of more than á thousand per cent, on then1 original investment. Moreover, the record of the Forbes case, decided in this court (and read in evidence in this case, by consent), shows that, in 1828, eleven years after the purchase, the appellants, or those under whom they claim, declared under oath that they had had “ peaceable possession ” of the land ever since their purchase. If, since that time,.or before it, an actual
pedis possessio
of these lands may have proved difficult or dangerous, owing to Indian wars, it surely cannot be seriously argued, that any warranty, expressed or implied, either by the civil or the common law, makes the vendor liable for the acts of a public enemy, or for a detention or disturbance of the possession by the act of the sovereign power. The purchasers have received full seizin and possession of these lands in the yéár 1819, under a title proved to be good and indefeasible; the execution of this mortgage is an assertion of the fact ;-they have neglected to comply with their contract to -pay. the money secured by the ■ mortgage for ten years, at least, without any apology; and it would be a strange doctrine indeed, .and 'one
equally unknown to the civil as to the common law, that an accidental disturbance of the possession by the public enemy, happening so many years after such default of payment, could retroact to justify its previous detention, or operate as a defence to the payment either of principal or interest.
Besides, if it were true that, during all this time, the vendee was unable to have such a possession of his land as to receive profits from it, the„ doctrine of the civil law, as quoted by the learned counsel for the appellant, — “ that the vendee is not hable for interest where' he received no profits from the thing purchased,” — has no application to the present case. It applies only to executory contracts, where the price is contracted to be paid at some future day, and the contract is silent as to interest. In such a case, the civiblaw will allow interest from the date of the contract of sale, if the vendee has had possession and received profits from the. thing purchased. In this it differs from the common law, which would not allow interest before the day fixed for payment, unless specially contracted for. But where the purchaser has contracted to pay on a given day, and neglects or refuses so to do, both law and equity subject him to interest as the measure of damages for the breach of his contract.
A second objection made to the payment of interest is, that the purchasers incurred much trouble and expense in obtaining any acknowledgment of their title from the United States, and, although it was finally decided by the Supreme Court. of the United States that their title was valid, yet that the courts of Florida had declared it invalid, and thus caused a cloud to hang over it for two or three years, which hindered the settlement, improvement, and sale of the lands.
It is hard- to conceive on what grounds these facts should constitute a defence to the payment of interest. The vendor
did
not, and no sane vendor would, covenant that his vendee should enjoy the property in all future time, free from unjust interruption or . oppression either by the sovereign power of the State, the public enemy, or individual trespassers. At the time this company purchased this claim from Forbes, the United States and Spain were in treaty for the cession of Florida; and doubtless it was the prospect of this change of sovereign, and the anticipated increase in value in consequence thereof, that moved'them to purchase this , large claim on speculation, and to covenant to pay the-money for it, without waiting to gee whether the United States would confirm the title, or without exacting from the vendors any covenant for the payment of any expenses to be incurred in obtaining the confirmation of their title by the new sovereign.
It may be admitted, also, that a court of equity would have enjoined the vendor from enforcing the collection of the pur- . chase-money .while the decree of the Florida court as to the title remained unreversed, from an apprehension of a total failure of Consideration; yet as that judgment
was
reversed, and as the vendee was never evicted or put out of possession, he could have ho claim to be released from paying interest,* even during, the time his title was thus unjustly subject to a cloud, much less for any term preceding its existence, or since its removal. As we have'already said, there was.no covenant in this sale, nor is there in this or in any sale, either of real or personal property, any implied warranty by the vendor that his vendee shall enjoy it for ever free from all unjust or illegal interference either by the. sovereign, or the citizen, or the public enemy.
If the money secured by this mortgage had been paid when it became due,, the mortgagee could have retained it with good conscience, and the mortgagor could have shown no right to recover it back'on the ground of failure of consideration; for. the consideration has not failed, and the title to the lands sold is indefeasible. And such being the case, it is hard to perceive any reason why the mortgagor should not be liable to the legal damages for detaining money which he was bound to pay.
Another reason urged against the allowance of interest in this case is founded on the allegation, that, from the death of Forbes, in 1822, till 1836, when John Innerarity took out letters of administration in Florida, there was no person to whom the mortgagors could legally make payment. But this argument is founded on a mistake of 'facts, as it appears clearly by the record, that,- whenever the mortgagors were ready or. willing to pay, they found persons ready to receive and give them a good and sufficient acquittance.
John Forbes was a trustee, as to this money, for the heirs of Pantón and Thomas Forbes. When the mortgagors called on the executors of John Forbes to make a partial payment on the mortgage, they declined to receive it, but directed the payment to be made to the
cestui que
trusts, which was accordingly done. In October, 4823, one half of the first instalment was paid .to William H. Forbes, acting for himself and the other heirs of Thomas Forbes. In the same year, also, the mortgagors. paid to James Innerarity, who represented the heirs of Panton, the sum of § 2,680.81, and in February, 1825, the further sum of §2,080.87.- There is no evidence of any tender of the balance, either to the executors of Forbes or to the
cestui que trusts.
This objection is therefore without foundation-; and ..this
exception to the decree of the Court of Appeals is overruled.
II. The second exception is to the refusal of the court to allow a credit of
£
375, claimed by the mortgagors.
After three of the five instalments into which the price of the lands was divided had been paid, but before the execution of the mortgage to secure the last two, it was discovered- that John and James Innerarity, who were owners of one fifth of the Panton interest (or one tenth'of the two thirds sold), would not assent to the sale made by John Forbes. Whereupon, as appears by all' the testimony and the admissions of the parties, it was agreed to refund to the purchasers a proportional amount (being one tenth) of the purchase-money. Accordingly, three several sums of-
£
375 were refunded to John,Camochan, who then represented the purchasers.
“
Besides which,” says Forbes, in his letter of 10th of December, 1819, “you will have to deduct from the acceptances due in 1820 and 1821
two
similar sums at these distinct periods.” On the trial below, the mortgagees insisted, that, as the mortgage was given for the balance due on the purchase nearly a year after the above-stated letter of Forbes, the fair presumption would be, that all the deductions for the defect of title in the Panton share had been already made, as the parties were fully aware of the difficulty, and had already refunded large sums on account of it; and, as further time was given in the mortgage for the payment of the last two instalments, it would not be probable that the parties had inadvertently given a security for a larger sum than was due. On the contrary, the mortgagors contended that they were entitled to a credit for two’sums of £375, according to the admission in Forbes’s letter. ■ The Court of Appeals allowed them a credit for one sum of £375, but refused to allow the other; which constitutes the ground of the second exception to the decree.
As the correctness of the position taken by either party, on this point, can be subjected to the test of mathematical calculation based on admitted facts, we are of opinion that ’ this exception - has not been sustained. The whole amount • of purchase-money for the two thirds conveyed was £15,000 sterling. The deduction for the Innerarity interest was one tenth, or £1,500, which would maké
four
instalments of £375 each. As the mortgage is given for the last two instalments without any deduction, and as it is admitted that three instalments of £375 each were refunded, it is plain that the fourth sum of £375 was not deducted from the mortgage, and equally plain that John Forbes was mistaken when he said that
two
sums of £375 remained yet to be deducted. The origin of this
. mistake can easily be discerned. The first payment was
me
fourth of the whole purchase-money, or £3,750; the one tenth refunded was £375; but as the remaining three fourths were divided into
four
instalments, each of £2,812 10s., the deduction from each would be but £281 5s. He overlooked the fact, that the last four instalments, being each one fourth less than the first, the amount to be deducted would be diminished in the same ratio. Thé oversight or mistake of Forbes in 1819 is not greater than that of both parties in 1820, when they included in the mortgage £375 which they knew was not due.' . But as the fact is fully established, that the only subject of deduction was one. tenth of the whole, and that three sums of £375 had been refunded," and ho more, the admission of Forbes, on the one side, and the presumptions ..of fact drawn from the execution' of the mortgage, on the other, must both yield to the certainty of arithmetic.
III. The third and last ground of exception urged by the appellants is the refusal of the court to allow them a credit for the sum of $ 13,357-75, paid to Thomas M. Blount, the agent and attorney of John Innerarity.
Some two years after the commencement of the litigation between these parties, the appellants made a payment to Thomas M. Blount of $ 13,357.75, under the following circumstances.
. It was admitted by both parties that a large-sum was due on the mortgage, but they "differed widely as to the amount. Innerarity. being, willing to receive any amount which the mortgagors were willing to pay, and give them a general credit for so much paid on account, without compromitting his "right to recover the whole amount claimed by him, gave a power of attorney to Thomas M. Blount, who was going to New York, where the appellants resided, “ to receive from the trustees of the Appalachicola Land Company, in the city of New York, any sum- or sums of money on account of and in part payment of the mortgage, <fcc., and to give such receipt or receipts, release or releases, therefor, as may be deemed requisite to exonerate the said trustees from so much of the said mortgage as may be paid by them on account and in part payment,” &c., &c.
With this power, of attorney, Blount proceeded to New York, and, instead of receiving such sums as the mortgagees might choose to pay on account, and gwing such receipts or releases as he was authorized to give, he assumed to adjust and settle with the company the whole balance due on the mortgage, and to act as if he had been authorized to arbitrate and decide all thematters in variance between the parties, an the controver-«Íes then pending án the; courts-of Florida. For the sum of $ 4,832.35, he gave the mortgagors a discharge for the balance
of the first instalment, including the disputed item of damages on the bill of exchange, claims, &c. And for a further sum of $ 8,525.38 he gave a discharge of one half the last instalment. Both Blount and the appellants well knew that Innerarity had uniformly and tenaciously claimed a much larger amount as due on each of these items; and they ought to have known, that, even if no more was justly due on them than the amounts paid, Blount had no authority to compromise or adjudicate on the justice of Innerarity’s claim. Besides these sums of money which are stated in Blount’s release to be the whole consideration thereof, he .received also a written contract of Messrs. Curtis and Griswold, to pay a further sum of ‡ 5,000, on certain
conditions;
but to whom, or how, or on what contingency, it is difficult to discover from any thing that appears on the face of the paper, or the evidence in the cause.
. Soon after, this transaction (on 20th January, 1840), Innerarity gave notice by letter to the appellants, that he repudiated the apt of Blount, and says: — “So soon after his return as I saw Mr. Blount,
he informed me of the provisional arrangement that he had made .with you, subject to my approval.
But this involved the suspension of the sum of $ 5,000, with the corresponding interest, &c., for which your contingent bond was proposed, &c., with the preliminary, however, of the cancellation of the moiety of the mortgage. This proposition, I confess, startled me,” &e.
The appellants, though thus informed by Innerarity that he considered “ Blount as. placed in the position of their agent,” and that he was unwilling to ratify “ this provisional arrangement,” nevertheless proceeded to put on record in Florida the release given them by Blount. . When this came to the knowledge of Innerarity, he again addressed them, by letter of 19th May, 1840, as follows: — “I addressed you a letter on the 20th of January last, and subsequently on the 25th of February, by original and duplicate, in which I advised you, that, having learned from T., M. Blount that he had an arrangement with you subject'to my approval,-aá he stated to me and others, in relation to a dischargé of one moiety of the mortgage, &c., I did not feel at liberty, as the representative' of the -interest of others, for the reasons stated in my said letter of 20th of January, to sanction the provisional contract which he made. To these letters I have received, ho answer, but to my great astonishment have just seen the deed of. release given to you on the 19th of September, by Mr. Blount, in which he proposes to act as my attorney, and which deed professes to discharge the trustees from one moiety secured by the above-
mentioned mortgage. In so doing Mr. Blount has transcended his authority as my attorney, as will appear by reference .to my letter of attorney, &c., &c. Feeling it to be my duty to disavow this unauthorized assumption of my attorney, and not less my duty to give you timely warning to protect yourselves from injury, I hereby notify you that I disavow and repudiate the deed of release, &c. I have not received, nor will not receive, any part of the money paid by you to Mr. Blount; but will look to you and the original security for the debt dué under the said mortgage.”
The receipt of these letters is admitted by the appellants in their answer to a supplemental bill filed by Iññer&rity (June 12th, 1840), for the purpose of having Blount’s release delivered up, and the whole transaction between him and the trustees declared fraudulent and void'. On the 6th of July, 1840; Camochan, one of the trustees, filed his cross bill to make Blount a party, and praying that, inasmuch as the money paid to him by the trustees had not been applied to the purpose for which it was designed, it may be paid into court'and held under their control. On the 9th of April, 1841, the appellants filed another cross bill, insisting on the full power of Blount in the transaction, and praying the court to confirm and establish the release, and to order satisfaction to be entered on the mortgage accordingly.
And finally, on the 27th of June, 1841, after it was ascertained that Blount and the Bank of Pensacola (of which he was president, add in which he had deposited the money) were both insolvent,, and that the money paid to him was lost, the appellants, in their answer to the cross bill,
for the first time,
offer “ to waive the said release,” and “ be satisfied that payment shall be held and regarded as on account of the mortgage generally, and be credited
pro tanto.”
On these facts, the appellants contend that they are entitled to a credit for the money paid to Blount, because he was authorized to receive it; and although the settlement he made and the release he gave may be void for want of authority, yet his acts, so far as they were authorized, were valid and binding on his principal.
“
Regularly it is true,” says Lord Coke, “ that when a man doth less than the commandment or authority committed unto him, then, the commandment or authority being not pursued, the act is void. And when a man doth that which he is authorized to do,
and more,
then it is good for that which is warranted, and void for the rest. Yet both these rules have divers exceptions and limitations.” (Co. Lit. 258
a.)
And
“
Lord Coke is well warranted,” says Mr.-Justice Story (Story
on Agency, <§> 166), “ in suggesting that there are exceptions and limitations. Where there is a complete execution of the authority, and something
ex abundanti
is added which is improper, then the execution is good and the excess only is void. But when there is not the complete execution of the power, or when the boundaries betweén the excess and the rightful execution are not distinguishable, then the whole would be void.”
It is contended, in the present case, that the excess and the rightful execution are easily distinguishable, and that the receipt, of the money was a valid act and'binding on his principal, though the settlement and release were void. But we are of opinion, that the appellants have not put themselves in a condition to have the. benefit of this principle. Blount’s power of attorney was a bare ■ nthority to receive money on account of the mortgage then in litigation, if the appellants chose to pay him any, leaving all the questions in dispute between the parties open to future adjustment. But the mortgagors' refuse to pay him money on the conditions on which he was authorized to receiye it, and give a valid acquittance. On the contrary, the money given to Blount is on their own terms, and in consideration of a settlement, arrangement, and release, which they knew, or ought to. have known, Blount had no authority to make. The money paid, the bond given, the receipt taken, discharging them from the balance claimed on the bill of exchange and from one half of the last instalment, constitute one transaction. Having advanced the money on their own terms and conditions, and not on those tendered by Innerarity, they put him into a situation in which he must either affirm or repudiate the whole transaction. For if he accepted' he mdney, they might insist that he could not reject the consideration on which it was given, on the familiar principle of the law, “ that the principal cannot ratify a transaction of his agent in part, and repudiate it as to the rest.” (Story on Agency, § 250.) Besides, by thus undertaking to enter into a treaty with Blount which they knew could not be binding without the assent of Innerarity, they- in fact constituted Blount their ambassador or agent to obtain its confirmation. They had a perfect right to refuse to pay money on the terms dictated by Innerarity in his letter of attorney; and Innerarity had an equal right to refuse it on their terms. And when informed by him, soon after the transaction, that he considers Blount as their agent, and that he had proposed this transaction as a provisional arrangement subject to the approval of Innerarity, they keep silence till he again repudiates the transaction and files a bill to set it aside, and never intimate
si
will agness
that Innerarity shall receive the money on the terms he offered, till near two years afterwards, when the iponey was lost by. the insolvency of Blount and the bank. This assent- of the appellants to the. terms of Innerarity came too late, after the money had been lost by their obstinate pertinacity in endeavours to compel him to accept it on their own terms.
We are of opinion, therefore, that the Court of Appeals have not erred' in refusing to credit .the appellants with this sum as a payment on the mortgage.
The decree of the Court of Appeals of Florida is therefore affirmed.
Order.
