    William H. Van Buren, Plaintiff in error, v. William H. Digges, Use of Joseph Libbey.
    Where a contractor engaged to build a house for a certain sum of money, and the owner of the house, when sued, offered to prove that there were' various omissions in the work stipulated to be done, and portions of the work were, done in a defective manner, not being as well done as contracted for, and filed a bill of particulars of these omissions and defects by way of set-off, this evidence was admissible. ■ - The old rule, that, where a party shall have been injured, either by a partial failure of consideration for the contract, or by the non-fulfilment of the contract, or by breach of warranty, he must be driven to a cross action, has been much relaxed in later times. The case of Withers v. Greene (9 Howard, 213) referred to and reaffirmed.
    Where the contract provided that,df the house were not finished by a certain day, a.deduction of ten per cent, from the price should be.made, and the defendant offered evidence to prove that this forfeiture was intended by the parties as liquidated ■ damages, the evidence was properly rejected. It would have been irregular in the court to go out of the terms of the contract- Unless the forfeiture had been expressly adopted by the parties as the measure of injury or compensation, it would have been irregular to receive the evidence where the inquiry was into the essential justice and fairness of the acts of the parties.
    Where the defendant offered to prove that certain work which he, the defendant, had caused to be done by a third person, was usual and proper, and necessary to the completion of the house, this evidence was properly rejected. He should have proved that it came within the contract. So, also, evidence was inadmissible that the defendant, in presence of the plaintiff, insisted upon its being within the contract; for this would have been making the defendant the judge in his own case.
    Mere acquiescence by the contractor in the defendant’s causing certain work to be done by a third person, will not exclude the contractor from the benefit of having further time allowed to finish the house. It was not necessary for him to make a special agreement that further time should be allowed, in consequence of the delay caused by this extra work.
    This case was brought up, by writ of error, from the Circuit Court of the United States, sitting for the County of Washington, in the District of Columbia.
    Oh the 7th of August, 1844, William H. Digges and William H. Van Burén entered into a contract in the city of Washington, as follows: —
    t! It is hereby agreed, between William Digges, of the city of Washington, carpenter, of the one part, and W. H. Van Burén, M. D., of the othér part, as follows:—
    
      u First. The said William Digges agrees to build, or cause to be built, for the said W. H. Van Burén, a house, with office, back buildings, woodhouse, stable, and privies, in the style and of the materials set forth in the following specifications, and represented in the accompanying plan, to wit: —
    '(Then followed numerous specifications.)
    “ Second. That the said W. H. Van Burén is to pay to said William Digges for the house built and finished as above specified, the sum of f 4,600 in gold or silver current money of the United States, or its equivalent in bank-notes, in the following manner; viz. $ 1,000 on the 1st day of September, $1,000 on the 1st of October, $1,000 on the 1st of November, and $ 1,600 on the day that the house is entirely finished and fit to occupy; provided that it shall not be later than tle 25th of December, 1844; he, William Digges, to forfeit ten per cent, on the whole amount if said house is not entirely completed and fit to occupy at the time agreed upon, viz. December 25th, 1844.
    •“ If there should be any matters of detail or finish, or matters not specified properly, and usually attached to or necessary to the completion of a house such as the one above specified, such things are to be considered as included in this agreement.
    “ If any disagreement should occur between the parties in this agreement with regard to matters above specified, such disagreement shall be settled finally and without appeal, by three persons, one of whom to be selected by each of the parties, and the third chosen by the persons thus selected, and, if necessary, by lot.
    “ In witness whereof, the said parties have hereunto set their hands and seals this 7th day of August, in the year of our Lord 1844.
    “• W. H. Digges,
    Wm. H. Van Burén.

    “ Signed this 1st day of September, 1844.
    “ Wm. H. Van Burén,‘ W. H. Digges.”
    On the 26th of June, 1845, Digges filed an account with the clerk of the Circuit Court, under the act of Congress passed on the 2d of March, 1833 (4 Stat. at Large, 659), entitled “An Act to secure to mechanics and others payment for labor done aná materials furnished in the erection of buildings in the District of Columbia”; and claimed the lien given by that act.

    On the 31st of January, 1846, Digges sued out a scire facias, on which the marshal returned made known. The defendant then put in a plea of non-assumpsit, and the case went on regularly in that form, no declaration having ever been filed, but it was agreed that a declaration should be considered as if embraced by the record.
    In April, 1847, the following notice of set-off was filed: —

    The bills of exception were as follows: —
    
      . Defendant's First Exception.
    
    Van Buhen v. Digges, Use of Libbey.
    
    “ The plaintiff, in support of the issue joined upon the plea of " non-assumpsit, produced and'proved written contracts between the parties, as follows (copied in pp. 461-463), and further offered evidence tending to prove that he had executed the work therein stipulated for, and had delivered it to the defendant, who received it without?objection. And thereupon the defendant offered to prove, by competent witnesses, that, before receiving, the said work, and during the progress thereof, he had objected to the sufiicier iy of various parts of the same as a compliance with the contract, and had communicated said objections to the plaintiff, and that there were various omissions of work stipulated to be done; and various portions of the work con-, tracted for were done in a defective and inferior manner, and not as well as contracted for by the plaintiff, and that some of these defects were not and could not be discovered by the defendant until after the defendant had entered into the possession and üse of the house; and the defendant offered to prove, by way of set-off, and having filed a bill of particulars of said alleged omissions and defects, and given due notice thereof to the plaintiff, and of his. purpose in reduction of the contract price of the whole work sued for by the plaintiff, the value of said omissions, and the difference in value between the actual work defectively executed and that contracted for; to which. evidence so offered, or any of it, the plaintiff objected as inadmissible under the issue; and the court, on the objection of the plaintiff so taken, refused to admit any of said evidence for said purpose; to which refusal the defendant excepts, and tenders to the court this his bill of exceptions, which is thereupon signed and sealed, this 14th, day of April, 1847,.
    “ W. Cranch,
    ■ James S. Moesell.”
    
      Defendants :Second Exception.
    
    “ In addition to the evidence contained in the aforegoing bills of exception on the part of defendant, and which áre' made a part hereof, the defendant, for the purpose of informing the court as to the relation and situation of the said defendant in regard to the said house, and the plan and building thereof, and the said plaintiff, at the time of the execution of the contract aforesaid, and the circumstances surrounding the-p'arties, and leading and inducing to' the said contract, offered evidence by T. P. Andrews, a competent witness, and who was present at the execution of said contract, and signed the same as a witness, tending to prove that the said defendant intended to reside in the said house with -his family as their permanent home; that the site of the same was “selected by him on account of its great convenience to be a place of business ; that'the plan thereof wras, in many respects, peculiar, and according to his own plan, and intended for his own convenience and professional habits ; and that the amount of ten per cent, on the contract price, stipulated by the contract aforesaid to be forfeited if the said house was not entirely, finished and fit to occupy, sí therein provided, on the 25th of December,' 1844, was intended by the said parties, at the time of entering into said contract, as and for the liquidated damages that would result and fairly belong to the said defendant by reason of said failure to finish the said house on the 25th of December, 1844; to which said offered evidence, and every part thereof, the plaintiff objected, and the court refused to hear.the same; to which refusal of the court the defendant, by his counsel, ex-eepts, and prays the court to sign, seal, and enroll this his bill of exception, which is accordingly done, this 15th day of April, 1847. W. Cranch,
    James S. Morsell, James Dunlop.”
    
      Defendant's Third Exception.
    
    “ Upon the further trial of this cause, and in addition to the evidence contained in the aforegoing bills of exceptions, the plaintiff having given evidence tending to show that the said defendant, while the said house was being built, made a contract for an alteration in the style and finish of the plastering of the said house, which contract was made with a third person, and not with the plaintiff, and thereby the execution of the work on the .said building was delayed beyond the said 25th of December, 1844; the defendant offered evidence tending to prove that the said plastering, and the style and finish thereof, was usual and proper and necessary to the completion of the said house; and further offered to prove, that at the time of the execution of the said plastering the defendant, in the presence of the plaintiff,, insisted on and required him to execute the same as a part of his contract, and that he refused so to do. To the admissibility of which said offered-evidence, and every part of it, the plaintiff objected, and the court refused to permit the same or any part thereof to go to the jury; to which refusal the defendant excepts, and prays the court to sign, seal, and enroll this his exception, which' is accordingly done, this 15th day of April, 1847.

      Defendant’s Fourth Exception.
    
    “ On the further trial of this cause; and after the evidence contained in the foregoing bills of exceptions, and which are made a part hereof, the defendant offered evidence tending to prove that he had paid, laid out, and expended various sums, of money to various persons other than the plaintiff, for and on account of the omissions and deficiencies 'in the work and materials done and furnished by the plaintiff, and omitted to be done and furnished by him under his said contract; and offered to prove, in connection therewith,:^hat such omissions and-deficiencies were in and about the work and materials furnished and done by the plaintiff'under his said contract; but the said plaintiff objected to the admissibility of the said offered evidence, and every part thereof, and the court refused to allow the same, or any part thereof, to go to the jury; to which refusal of the court the defendant.excepts, and prays the court to sign, seal, and enroll this his exception, which is accordingly done, this 15th day of April, 1847.
    W. Cranch,
    .Jas; S. Morsell.”
    
      Defendant’s Fifth Exception. .
    
    “Upon the further-trial of this cause,., the plaintiff having given evidence in addition to that contained in the aforegoing bills of exceptions, and which are made a part hereof, tending to prove that he had, at the request of defendant, in addition to the work and labor and materials provided for in the Said contract, done and performed certain extra -work, and furnished extra materials on and about the said house and premises, and for which he claimed extra compensation and damages over .and above the amount specified in the said contract, and the defendant, .having offered'evidence tending to prove that-he did not consent to any extension of the time for completing the said house 'as provided by the said' contract-, prayed the court to instruct the jury, that if, from the whole- evidence aforesaid, the jury shall believe that any extra work ordered or sanctioned by defendant beyond that provided for by the written agreements did not entitle.the plaintiff to any extension of time in the completion of said work, unless the jury shill find that at the time of agreeing for said work it was distinctly understood that extra time should be allowed in consequence, and then only to the' extent of the time actually agreed upon, or in' the absence of. any agreement for .a precise time, to such extent as-was reasonably necessary for such extra work; which instruction the court gives, and on the prayer of the plaintiff adds-thereto: But the court further instructs the jury, that the defendant is riot entitled to set off in this action the sum. of ten per cent, on the amount of the contract mentionéd in the proviso in the said contract, nor any damages which may have resulted to the defendant by any delay on the part of the plaintiff in completing the said house, and delivering the. same to the defendant on the said 25th. of December, 1844. To which modification of the court and instruction on the part of the plaintiff^ as above granted, the defendant excepts, and prays the .court to sign, seal, and enroll this his bill of exceptions, which is accordingly done, this 15th day of April, 1847.
    W. Chano», ' ■Jas. Dunlop.”
    
      Defendant's Sixth Exception.
    
    “ And the said plaintiff, having further given evidence tending to show that, after the plastering of the said house, had been begun, the defendant entered into a contract with the plasterer to make cornice and centre-pieces for the parlors and passage, that a delay in the work for a week was occasioned by the negotiation leading to the said agreement, and a further delay of two weeks was occasioned by the work required • on the said additional plastering, and part of the same being frozen insomuch that the said plasterer did not and could- not finish the said work until some days after the said 25th of December, 1844, and much of the carpenters’ work and the painters’ was ■thereby postponed and delayed until after' the said day; the said defendant then gave evidence to show that the plaintiff knew of the said agreement for the said additional plastering, and did not object-thereto.
    “ And thereupon the defendant prayed the court to instruct the jury: If the jury shall find, from the evidence, that any delay was caused in completing the work in consequence of the extra plastering in the parlors and passage, done under the distinct contract between the defendant and Messrs. Brown, given in evidence, and-they shall further find that said extra- plastering was so done with the full knowledge and sanction of the plaintiff, and without any understanding between him and the defendant at the time, that in consequence thereof a further time should-be allowed for . completing the building, then the plaintiff is not entitled to any further time for completing the building because of such work and the delay attending the same.
    “ That the forfeiture of ten per cent, in the contract price of the work for a failure to complete the same by the 25th .of December, as stipulated in the written, contract given in .evidence, is to bé held as the liquidated amount of damage for the failure-to c.omplete the work in that time, and the defendant is entitled to a deduction of the full amount thereof from the specified price of the work, unless the jury shall find that the failure to complete the same by said date proceeded wholly from the acts or default of the defendant, so that, independently of such acts or default, he would have so completed it within said time.
    “ Which instructions, and. each of them, the court refused to give ; to which refusal of the court the defendant excepts, and prays the court to sign and seal this his bill of exceptions; which is done accordingly, this 15th of April, 1847.
    W. Cranch,
    James S. Morsell, James Dunlop.”
    
      Defendant's Seventh Exception.
    
    “ If the jury shall find, from the evidence aforesaid, that the plaintiff contracted with the defendant, in writing, to build, complete, and deliver the said house to him on or before the 25th of December, 1844, and that the plaintiff failed so to do, and shall further find .that the time for said completion and delivery was not exténded beyond the said 25th of December, 1844, by the agreement of the said- plaintiff and defendant, or by the act of the defendant, then the plaintiff is not entitled to recover in this' action.
    “ Which the court refused to give; to which refusal the defendant prays leave to except, and that the court will sign and seal this his bill of exceptions; which is accordingly done, this 15th of April, 1847. W.. Cranch,
    James S. Morsell.”
    
      Defendant's Eighth Exception.
    
    “ If the jury find, from the evidence aforesaid, that the plaintiff contracted, by the. contract of the day of aforesaid, and the additional agreement thereto of the day as aforesaid, to build, complete, and deliver to the defendant the said house orí or before the 25th of December, 1844, and that the plaintiff failed so to do, then the defendant 'is entitled to claim ten per cent, as a deduction on the whole amount of the contract price from the claim of the plaintiff; provided the jury shall find, from the evidence, that the plaintiff could reasonably have so completed and delivered the said house on the 25th of December aforesaid, and notwithstanding the jury may further find that the building and completion thereof were delayed by the áct. of the defendant.
    “ Which instruction the court refused to give; to which refusal the defendant excepts, and this his bill of exceptions is signed, sealed, and ordered to be enrolled, this 15th of April, 1847. W. Cranch,
    James S. Morsell, James Dunlojp.”
    
      .Defendant's -Ninth Exception.
    
    “ If' the jury find, from the evidence, that the plaintiff contracted with the defendant to'build, complete, and deliver to him the. said house on the 25th of .December, 1844, and failed só to do, then the defendant is entitled to claim ten percent, on the amount of the whole price of the contract, as a deduction from the plaintiff’s claim. •.
    “ If the jury shall find, from the evidence, that the plaintiff contracted with the defendant, in writing, to build, complete, finish, and deliver to him the said house on or before the said 25th of December, 1844, and shall further find that the said plaintiff failed so to do, and that the time for'said completion and delivery was not extended by agreement of the parties beyond the said 25th of December, 1844, then the plaintiff is not entitled to recover in this action:
    “ Which instruction the court refused to give. Whereupon the defendant, by his counsel, excepted to .said refusal, and prayed the court here to sign and seal this his bill of. exceptions ; which is accordingly done, this 15th of April. 1847.
    W. Cranch,
    James S. Morsell, Jame3 Dunlop.”’
    Upon these exceptions, the case cáme up to this court.
    It was argued by Mr. May, for the plaintiff in error, and Mr. Bradley, for the defendant in error.
    
      Mr. May, for the plaintiff inr error,
    contended that the Circuit Court had erred.
    The principle asserted in the first, fourth, and fifth exceptions is understood to be, —:
    That in an action to recover the stipulated price on a special contract (to build a house, where the house, when built, has been accepted), evidence cannot be offered to show a.partial failure, to perform the same, according to its terms. Neither, can money paid to a stranger to complete the same or on account of said failure, nor any evidence of damages- suffered by reason of such failure, be offered to reduce the said price, even though the same be specially pleaded, or notice by way of set-off, with a particular aceoimt thereof, be filed in the case.
    
      Against this principle the following authorities will be relied on. Act of Assembly of Maryland of 1785, ch. 46, § 7; Evans’s Maryland Practice, 153; 2 Evans’s Harris, 37 ; 2 Greenleaf’s Evidence, § 136, and cases there cited; Basten v. Butter, 7 East, 482; Poulton v. Lattimore, 9 Barn. & Cress. 263; Runyan v. Nichols, 11 Johns. 547; Withers v. Greene, 9 Howard, 213.
    The second exception denies that it is the duty of the court to hear evidence to aid its exposition of a doubtful intention appealing in a written instrument, so as to give it effect according to the real intentions of the parties.
    Against this will be cited, i Greenleaf’s Evidence, § 277; Gray v. Harper, 1 Story, 574; Smith v. Bell, 6 Peters, 75; Bradley v. Steamboat Co., 13 Peters, 99.
    The fifth and eighth exceptions -declare that the sum of ten per cent., as agreed by the s.aid contract to be forfeit, in ease the .said house was not completed and delivered by the 25th of December, 1844, was intended by the parties as “ a penalty,” and not as “liquidated damages,” and could not be set off or discounted against the plaintiff’s claim.
    Against this will be cited, 2 Pothier on Obligations, by Evans, note No. 12, pp. 85-98; Davies v. Penton, 6 Barn. & Cress. 224; Lindsay v. Anesley, 6 Iredell, 189; Fletcher v. Dyche, 2 Term Rep. 32; Huband v. Grattan, 1 Alcock & Napier, 394; Crisdee v. Bolton, 3 Carr. & Payne, 240; Leighton v: Wales, 3 Meeson & Welsby, 545; Nobles v. Bates, 7 Cowen, 309; Dakin v. Williams, 17 Wendell, 454; Allen v. Brazier, 2 Bailey, (S. C.) 295; Brewster v. Edgarly, 13 N. Hamp. 277; Mead v. Wheeler, Ibid. 354.
    
      Mr. Bradley, for the defendant in error,
    referred to the following authorities: —
    On the first point, 12 Wheaton, 183,189, 193.
    Second point, 13 Peters, 99.
    Third point, 7 Wheaton, 13, 16,17, 18.
   Mr. Justice DANIEL

delivered the opinion of the court.

The defendant in error, in a form of proceeding practised in the court of Washington, instituted a suit in the nature of an action of assumpsit against the plaintiff, upon a contract-in writing for building a house. The contract between these parties, which is drawn out' in much minuteness of detail, it is not deemed necessary to set forth here in extenso in order to a correct understanding of the questions of law raised upon this record. Enough for that purpose will be shown in the following extracts from the agreement above mentioned.

After giving the dimensions of the house to be built, tlie contract proceéds with these stipulations concerning the work to be done, and the compensation to be paid therefor: —

“ House to be built of two stories, with attic chambers above, of first-rate materials throughout, including office and back buildings, and in the best and most modern style, of workmanship, and to be entirely finished and fit for occupation on or before the 15th of December, 1844.
“ For the brick-work throughout, the best hard-burned red brick are to be employed, with sharp river sand and best lime. For the flooring throughout, thé best quality narrow North Carolina yellow heart pme, tongued, grooved, and secret nailed. Roofs to be slated in the best manner. Spouting to be thoroughly arranged, in the least conspicuous manner, so as to carry off all the water that falls on the roofs of the main building,- office, and back buildings. Door and window frames and doors to be. of perfectly seasoned material, warranted not to shrink.”

After a long detail, having reference rather to an enumeration than' to the quality of the several things to be .done in completing the house and offices, the' agreement concludes in these words: — “ That the said William H. Van Burén is to pay to the said William .Digges for the house built and finished as above specified,- the sum of $ 4,600 in gold" or silver current money of the United- States, or its equivalent in bank-notes, in the following manner; viz. $ 1,000 on the 1st day of September ; $ 1000 on the 1st day of October.; $.1,000 on the 1st day of November; and $1,600 on the day-that the house is entirely finished and fit to occupy, provided that it shall not be later than the 25th day of December, 1844; he, the said William .Digges, to forfeit ten per cent on the whole amount, if the said house is not entirely completed and fit to occupy at the. time agreed upon, viz. December 25th, 1844.”

Subsequently, viz. on the 1st day of. September, 1844, the-above agreement was • altered by the parties in the following, particulars, vw “that in place of the attic story with rooms, as specified in .the above contract, William H. Digges is to build a third story, divided arid finished in all respects like the second story”; arid after reciting some directions with respect to divisions and arrangements in this third story, the hew agreement provides for the “ finishing of a garret; to be floored, plastered, and divided as agreed upon, with the necessary stairways, in the best manner and with the.same materials employed in the second story.”

For the work to be performed under this new agreement,' when it should be cotnpleted, the plaintiff in error was to' pay the additional sum of $ 525 ; but no stipulation appears therein as to the time within which this additional work was to be completed.

The plaintiff in error, the defendant below, pleaded the general issue (inon assumpsit), filed a bill of particulars amounting to the sum of $ 707, for moneys paid, expenses incurred, and damage sustained, by reason of the non-performance by the plaintiff of his agreement; and filed also with this bill of particulars a notice in writing, in which the amount of that bill was claimed in diminution of the plaintiff’s demand. Upon the issue joined, the jury rendered a verdict for the plaintiff, for the sum of $ 1,223.21, with interest from the 21st .day of August, 1845, till payment, and for this sum, with the costs of suit, the court gave judgment against the defendant below.

At the trial of this cause, there were nine separate prayers to the court, and nine bills of exceptions sealed to the rulings of the court upon the prayers thus presented to them. Some of these exceptions it will be unnecessary particularly to discuss,

’ as they are clearly embraced, if not within the terms, certainly within the meaning, - of others which were taken. We will therefore examine those exceptions only which.aré regarded as-propounding in themselves some distinct and separate legal principle. '

The first exception by the defendant below, the plaintiff in error-here, is as follows —

“ The plaintiff, in supportof the issue joined upon the plea of non assumpsit, produced and-proved written contracts between the parties, as follows (copied in pages 461 — 463), and further offered evidence tending to prove that .he had executed the work therein stipulated for, and had delivered it to the defendant, who received it without objection. And thereupon the defendant offered to prove, by competent witnesses, that, before receiving said work, and during, the progress thereof, he had objected to the sufficiency of various parts of the same as a compliance with -the contract, and had communicated said objections to the plaintiff, and that there were various omissions of work stipulated to be done, and various "portions of the work contracted for were done in a defective and inferior manner, and not as well as contracted for by the plaintiff, and that some of these-defects were not and. could not be discovered by the defendant, until after the defendant had entered into the possession and use of the house; and the defendant offered to prove, by way of set-off, and having filed a bilí of particulars of said alleged omissions and defects, and given, due notice thereof to the plaintiff, and of his purpose in reduction of. the contract price of the whole work sued for by the said plaintiff, the value of said omissions, and the difference in value between the actual work defectively executed, and that contracted for; to which evidence so offered, or any of it, the plaintiff objected, as inadmissible under the issue, and-the court, on the objection so taken, refused to admit any of said evidence for said purpose.”

The decision of the Circuit Court, rejecting the evidence described and tendered for the purposes set forth in this exception, cannot be sustained upon any sound legal principle.

We are aware of the rule laid down in the earlier English cases, which prescribed that in all instances wherein a party shall have been injured, either by a partial failure of consideration for the contract, or by the non-fulfilment of the contract, or by breach, of warranty, the person so injured could no.t in an action against him upon the contract defend himself by alleging and proving these, facts ; but could obtain redress only by a cross action against the party from whom the injury shall .have proceeded. .This doctrine of.the earlier, cases has been essentially modified by later decisions, and brought by them to the test of justice and convenience, which requires, that whenever compensation or an equivalent is claimed by á party in return for the performance of conditions for which such compensation or equivalent has been stipulated, the person so claiming is bound to show a fulfilment in good faith of those conditions; and the party against whom the claim shall be made shall be permitted to repel it by proof of an entire failure to perform, or of an imperfect or unfaithful performance; or by proof of injurious consequences resulting from either of these delinquencies; and shall not be driven exclusively to his cross action. Of this doctrine the following examples, amongst others to be. found, may be adduced from the-English courts.

Per Parke, Justice, in the case of Thornton v. Place, 1 Moody & Robinson, 219, it is said: “ When a party engages to do certain work on certain specified terms, and in a specified manner, but in fact does .not perform the work so as to correspond with the specification, he is riot of course entitled to recover the price agreed upon in the specification; nor can he recover according to the actual value of the work, as if there had been no special.contract. What the plaintiff is entitled to recover is the price agreed upon, subject to a.deduction, and the measure of that deduction is, the sum which it would take to alter the work so as to make it correspond with the specification.”

In Chapel v. Hicks, 2 Carrington & Marshman, 214, it is said: “ In an action on a special contract for work done under the contract, and for work and materials generally, the defendant may give iri evidence ■ that the work has been done improperly, and not agreeably to the contract; in that case, the plaintiff will only be entitled to recover the real;value of the Work done and materials supplied.”

In the case of Cutler v. Close, 5 Car. & Payne, 337, where a party had contracted to supply and erect a warm-air apparatus for a certain sum, it was ruled, in an action for the price (the defence to which was, that the apparatus did not answer), that, if the jury thought it was substantial in the main, though not quite so complete as it might be under the contract, and could be made good at a reasonable rate, the proper course would be to find a verdict for the plaintiff, deducting such sums as would enable the defendant to do what was requisite. And Tindal, C. J., in his instructions to the jury, uses this language: “ The plaintiffs say that they have performed their contract, and are entitled to be paid. On the contrary, the defendant says that the apparatus is not at all of the sort he contracted for; and therefore he is not liable to pay for it. The law on the subjeet, as it seems to me, lies in a narrow compass., If the stove in question is altogether incompetent, and unfit for the purpose, and either from that, or from the situation'in which it is placed, does not at all answer the end for which it was intended, then the defendant is not bound to pay. If it is perfect, and the fault lies in management at the chapel, then the plaintiffs will be entitled to recover the whole price. But there is another view of the case. The apparatus may be in the main substantial, but not quite so complete as it, might be according to the contract; and in that case, if it can be made good at a reasonable expense, the proper course will bej to give your verdict for the plaintiffs, deducting such sum as will enable the defendant to do that which is requisite to make it complete.”

But, as conclusive with this court upon this point, it may be ■ remarked, that it was carefully considered at the last term in the case of Withers v. Greene, 9 Howard, 213; the decisions applicable thereto from the courts both in England and the United States were then collated and- examined, and upon that examination the doctrine herein above propounded received the concurrence of all the judges. Again expressing our approbation of this doctrine, we conclude that the proof tendered, as declared in the first exception of the defendant below, should have been admitted, and that the Circuit’ Court erred in ruling, its exclusion from the jury.,

The second exception by the defendant states, that, in addition .to the evidence previously tendered by him, he offered proof tending to show the peculiar adaptation of the house contracted for, both in its design and situation, to the defendant’s personal and professional pursuits and convenience, and that the amount of ten per centum on the contract price stipulated to be forfeited if the house was not entirely, finished and ready for occupation, as therein provided, on the 25th of December, 1844, was intended by the parties--as and for liquidated damages, that would result and fairly belong to the said defendant by reason of said failure to finish the said house on the 25th of December, 1844; and that the court refused to hear the evidence thus tendered. In the refusal of the court to admit the evidence thus tendered we think they decided correctly. It would have been irregular in the court to go out of thé terms of the contract, and into the consideration of matters wholly extraneous, and with nothing upon the face of thewriting pointing to such matters as proper or necessary to. obtain its construction or meaning. The clause of the contract. providing for the forfeiture of ten per- centum on the amount of. the contract price, upon a failure to complete the work by a •given day, cannot properly be regarded as an agreement or settlement of liquidated damages; The terrp. forfeiture imports • a penalty ;■ it has no. necessary or natural connection with the measure or degree of injury which may result from a-breach of contract, or from an imperfect performance. It implies ati absolute infliction, regardless of the nature and extent of the causes by which it is superinduced. Unless, therefore, it shall have been expressly adopted and declared by the "parties to be a measure of injury or compensation, it is never taken as such by courts of justice, -who-leave it to be enforced where this can be done in its real character, viz. that of a penalty. In a defence like-that attempted by the defendant in the Circuit Court, upon the essential justice and fairness of .the acts of the parties, a positive immutable penalty could hardly be applied as a fair test of their' merits.

In the third exception by. the defendant, it is" stated'that the plaintiff, having given evidence to show that the defendant, whilst the house in question was being built, made a contract, for an alteration in the style and finish of the plastering of the house, with a third person, and not with the plaintiff; and thereby the execution of the work on the said building was delayed beyond the 25th of December, 1844; the defendant . offered evidence tending to prove that the,said plastering and the style and finish thereof were usual and proper and necessary to the completion of the said house; and further offered to prove, that, at the time of the execution of the said plastering, the defendant in the presence of the plaintiff insisted on' and required him to execute the sanie as a part of his contract; and that he refused so to do, and that to the admissibil-. ity of this evidence, objection "being made, it was excluded •from' the jury by the court. In this decision the court were certainly correct.- The defendant could- have-no right to insist upon the performance of plastering, or of any other description of work, unless it came within-t-he provisions of the contract; the simple fact that the work - demanded, was suitable to the' style of the defendant’s house, could give him no right to demand its execution, unless the plaintiff had contracted-for its. . performance. It was incumbent, therefore, on the defendant, to prove by legal evidence that the work demanded by him was within the provisions of the contract; but instead of doing this, he insisted upon showing merely that he, the defendant, had determined this work to be proper and within the,pro-, visions of the contract, and that the plaintiff’s non-concurrence in this determination, and consequent refusal to do what the defendant required, were to be received as proof of a failure on the part of the plaintiff to perform his contract ;> an 1 as forming a just ground with the defendant for his resistance, to the' action. It would' indeed have been -strange, if the court could have tolerated such an irregularity as this; by which the defendant would have been permitted to become a witness in his own behalf.

The fourth and fifth exceptions on the part of the defendant below, relating merely to the admissibility ■ of testimony to show a failure to perform, or an incomplete performance, on the part of the plaintiff, are embraced within the first exception already considered, and the rulings of the court as to these two last instances being in contravention of our opinion as declared upon the first exception, are pronounced by this court to be erroneous.

In the- sixth exception of the defendant, two subjects essentially distinct in character are blended. As to the first, it is stated that the plaintiff, having further given evidence tending to show that, after the plastering of the house was begun, the' defendant entered into a contract with the plasterer to make cornices and centre-pieces for the parlors and passages; that a delaji in the work, for- a week was occasioned by the negotiation leading to the said agreement; and a further delay of two weeks by the additional plastering, and part of the same being frozen, insomuch that the plasterer could not finish the work until some -days after the. 25 th of .December, 1844, and much of the' carpenters’ wqrk ' and- the:--painters’ was thereby postponed .and delayed until after ihe said day; and the said defendant theff'gáve evidence to .show that the plaintiff knew- of the said agreement for the- said additional plastering, and did .not object thereto. ■ And thereupon the- defendant prayed the court-to instruct1’the jury7, that-if they shall find that.any delay was caused in completing the work in consequence of the ex* tra plastering in the parlors and passage, done under the dis'tinc-t contract therefor given in evidence, and they shall further find that said extra plastering was so done with the full knowledge* and sanction of the plaintiff, and without any understand-, ing between him and the defendant at the time, that in consequence thereof a further time should be allowed for completing the building, then the plaintiff is not entitled to any further time for completing the building because of such work, and the delay attending the same.

The second subject embraced in this exception is the.forfeiture of ten per centum upon the contract price of the work, >v.hich the court was asked to declare was the amount of liquidated damages, the whole amount of which on the price of the work the defendant was authorized to claim for a failure to complete the work by the- 25th of December, 1844, unless the jury should find that the failure to complete. the work proceeded wholly from the acts or default of the defendant. The refusal by the Circuit Court of both the instructions appearing upon this exception is entirely approved.

It is difficult to conceive, upon what ground the defendant could be permitted to interpose an obstruction to the fulfilment of the contract, and then to convert that very obstruction info a merit on his own part, or into the- foundation of a claim against the party-whom he had already subjected to the inevitable consequences of the obstruction so interposed; an inability to comply with his engagement, ahd a postponement of the fruits of a compliance therewith, if that had been permitted. Mere acquiescence in this irregularity by the plaintiff should not subject him to farther mischief. With respect to the second subject embraced in this exception, vik. the forfeiture of ten per centum claimed by the defendant, we deem it unnecessary to add to what has been already said on that subject. We will here remark, once for all, with respect.to this penalty, that, as it constitutes the only ground for the. eighth and ninth exceptions taken by the defendant below, those exceptions must be regarded as expressly overruled.

" By the' seventh exception of the defendant below, it appears that the court were asked to propound as the law, that if, from the evidence, it should appear that the plaintiff contracted with ■the defendant in Writing, to build, complete, and deliver the said house, to him on or before the 25th day of December, 1844, and that the plaintiff failed to do so; .and the jury shall find that the time for said completion and delivery was-not extended beyond the said 25th of December, 1844, by the agreement of the said plaintiff and defendant, or by the act of the defendant, then the plaintiff is not entitled to recover in this action, which instruction the court refused to give.

The ruling of the court, as set forth in this exception, though not reconcilable 'with their own decision on the first prayer presented to them by the defendant, is in accordance with the opinion we have expressed in reference to the questions raised by that prayer, and also with the doctrine ruled by this and in other tribunals upon those questions, as in treating of that first prayer we have already shown. It places the parties upon the true ground of contestation between them, viz. the truth, the extent, and manner of performance on the one hand; the degree of injury, from omission, neglect, or imperfection of performance on the other. The ruling of the Circuit Court, therefore, upon this exception, is' entirely approved; but as that court has erred in its decision in reference to the prayers in the first, ' fourth, and fifth exceptions of the defendant, its decision as to those prayers is hereby reversed, with costs, and this cause is remanded to the Circuit Court, with orders for.a venire facias for a new trial in conformity with the principles expressed in this opinion.

Order.

This cause came on to be heard on the transcript of the record from the Circuit Court of the United States for the District of Columbia, holden in and for the County of Washington, and .was argued by counsel. On consideration whereof, it is now here ordered and adjudged by this court, that the judgment of the said Circuit Court in this cause be, and the same is hereby, reversed, with costs, and that this cause be, and the same is hereby, remanded to the said Circuit Court, with directions to award a venire facias de novo.
