delivered the opinion of the Court.
The appellee sued the appellant on the common counts for a balance claimed to be due for work done and materials provided, etc., under the following circumstances: The appellant owned a house known as No. 3038 Elliott street, at the corner of Canton street in Baltimore City, which was built without a cellar, was not plastered or partitioned off on the second story, and the rear was arranged for a stable. The appellee entered into a contract in writing with the appellant which states: “Cellar to be dug under the entire store to the partition wall between kitchen and store to a depth of 7 feet, and walls to be underpinned with good hard brick laid in cement. * * •* cellar to be connected with sewer and cemented,” and provides for work to be done in the kitchen, the second story of the house and a number of other things not necessary to mention. It concludes, “I will do the work and furnish material for the sum of fifteen hundred dollars ($1,500).” The paper was drawn in the shape of an estimate or bid, but was *226 accepted by the appellant and the appellee identified it as his contract.
The appellee began the work in April, 1903. He gave the contract to build the cellar to a sub-contractor who started to excavate. The appellee thus described the conditions of the ground: “The house stood on a hard crust about three feet thick and the foundation of that house didn’t extend through that hard crust, it was built on that crust and the more we got through that the more we got into a swamp, like the bottom of an old creek, black, muddy stuff and soft and they tried to dig and dig and it all ran into this place and finally a big lump would cave off and fall in every now and then and they continued on that way to get a trench dug to connect the cellar with the sewer so we thought we could drain the place a little.” His foreman notified him that the house was cracking, and he then got lumber and drove “lagging” in to hold the ground. He testified that he notified Mr. Preston, the Building Inspector of the city, who went there with one of his assistants; that they “took sticks and shoved them down in the ground about fourteen feet deep, that Mr. Linz was present upon this occasion.”. He also said that Mr- Preston told him no cellar could be made and he should fill in what he had taken out and he stopped the work. He further testified that the appellant called on him “off and on” and wanted to see “whether we couldn’t make a cellar there; wouldn’t it be possible in some way to overcome it even if a small cellar.” They finally thought they “could make a little cellar to get so’me cellar there,” and he said “let the thing lay and we will drain the ground into the sewer and may be we can overcome it provided you pay the additional post and stand the consequences.” He demanded a writing from the appellant and he'said “his word was as good as mine, and if I put a cellar there he would see that I got pay for it; that he would pay for the additional work I was compelled to do to make a cellar.” In another place he stated; “He says if I was able to get a cellar'under there he would reimburse or pay me the additional cost, whatever it was, to get a cellar there; that the *227 house was no good to him without a cellar.” In October he went to work again, dug out eight feet, then drove poles down eight feet long, used “concrete and cement in there to form our footing” and went to great expense and trouble to make the cellar, under the new arrangement.
The appellant introduced evidence which tended to show that some of the trouble about the cellar was owing to the negligent way in which the appellee’s men did the work, and that the bad condition of the soil did not extend as deep as the appellee said it was, but there can be no doubt that the conditions were altogether different from what appeared on the surface or what was anticipated. The appellee also testified that before he made the offer he “wanted to know how the ground was and defendant took plaintiff in the cellar of his building” (which was on the opposite side of the street) “and he showed me he had a cellar dug there and it went all right, and the soil was nice and sound there on the other corner, and when I started I wouldn’t have any trouble, and I made my figures on his say so.” After the work was begun, the owner of the adjoining property sued the appellant and the appellee for damages to her house sustained by reason of the excavation, and the suit was compromised by the appellant buying the house and -the appellee agreeing to put it in proper condition. That was No. 3036 Elliott street.
The principal question in the case is whether the plaintiff was entitled to recover for the additional costs and expenses incurred, by reason of those conditions, on the promise of the appellant to pay him for them. The precise question for our consideration is presented by the plaintiff’s fifth prayer, which was granted. After referring to the written contract made in April or May, 1903, and the refusal of the plaintiff in June, 1903, to perform and complete said contract, the prayer further submitted to the jury to find whether “said refusal on the part of the plaintiff was induced by
substantial and unforeseen difficulties
in the performance, which would cast upon the plaintiff
additional burden not anticipated by the parties when the contract was made,
and if they further find that after said refusal
*228
by the plaintiff, the defendant to induce the plaintiff to resume the work thus abandoned promised him to see him through and to stand the consequences, and that relying upon said promise the plaintiff completed the work, then their verdict may be for the plaintiff,” etc. That prayer seems to have followed quite closely the language used in
King v. Duluth M. & N.Ry. Co., 61
Minn. 487 (s. c.
We have thus referred to, and quoted from, that case at unusual length because the principles therein announced seem to us to be, not only well and clearly stated, but just, and founded on reasons that any Court of justice should hesitate to reject, unless they conflict with some binding authority or *230 established rule of law, which in our judgment they do not. When two parties make a contract based on supposed facts which they afterwards ascertain to be incorrect; and which would not have been entered into by the one party' if herbad known the actual conditions which the contract required him to meet, not only Courts of justice but all right thinking people must believe that the fair course for the other party to the contract to pursue is either to relieve the contractor of going on with his contract or to pay him additional compensation. If the difficulties be unforeseen, and such as neither party contemplated, or could have from the appearance of the thing to be dealt with anticipated, it would be an extremely harsh rule of law to hold that there was no legal way of binding the owner of property to fulfill a promise made by him to pay the contractor such additional sum as such unforeseen difficulties cost him. . But we do not understand the authorities to sustain such a rule, on the contrary they hold that the parties can rescind the original contract, and then enter into a new one, by which a larger consideration for the same work and materials that were to be done and furnished under the first contract can be validly agreed upon. Persons competent to contract can as validly agree to rescind a contract already made, as they could agree to make it originally, but we are met with the contention (which it must be admitted is sustained by Courts of high authority) that while this is true, yet after a contract is broken by one of the parties the other cannot waive his right to treat it as no longer existing and bind himself to pay more than the original contract called for, unless the orignal contract is actually rescinded.
Such authorities are based upon the ground that there is no consideration for the promise, and in that connection we will review the decisions of this State as to whether a moral obligation is sufficient to support a contract, as there is some conflict between them, and consequently a misunderstanding as to what the law of this State is on that subject. In
State v. Reigart,
I Gill, I, our predecessors held that, “A contract founded upon an equitable duty, such as would be enforced
*231
by a Court of equity, or upon a moral obligation, which no Court of law or equity can enforce, or to do that which an honest man ought to do, or upon the waiver of a legal right by thi. party entitled to it is maintained by a sufficient consideration.” That decision in reference to the moral obligation was based on what Lord Mansfield had said in
Hawkes
v.
Saunders,
Cowper, 289, although at that time his doctrine had been overruled in England.
Eastwood
v.
Kenyon,
11 Ad. & E. 438. In
Ellicott v. Peterson,
In
Ingersoll
v.
Martin,
» We are, however, of the opinion that this prayer can be sustained on the ground stated in King v. Duluth, etc., Ry. Co., supra, and other cases, which is, as expressed in that case, that “by the voluntary and mutual promises of the parties their respective rights and obligations under the original contract are waived, and those of the new or modified contract substituted for them.” When there is such a strong moral obligation as there was in this case to give the appellee relief, it would be making an exceedingly technical distinction to hold that the promise would have been binding if the original contract had been expressly rescinded, but that is not binding because there was no express or actual rescission, although the facts show that it was undoubtedly intended by the parties that neither should be held to the terms of the original contract. Of course it will be borne in' mind that the *233 Court in King v. Duluth, etc., Ry. Co., only applied the principle announced to cases where the refusal to perform was equitable and fair; and the difficulties were substantial, unforeseen and not within the contemplation of the parties when the original contract was made. The opinion also excluded from the application of the principle mere “inadequacy of the contract price which is the result of an error of judgment, and not of some excusable mistake of fact.” We need not go further than the doctrine announced by that case; but there are many others based upon the principle of waiver, some of them not being affected or governed by the motive of the promisee in refusing to perform the original contract, and we do not want to be understood by referring to or quoting from them as meaning to adopt all that is said in them.
In
Meech
v.
Buffalo,
In Anson on Contracts, 76, after speaking of the well known case of the sailors not being entitled to recover more than their contract called for, it is said: “It would have been otherwise if risks had arisen which were not contemplated in the contract. For instance, such a contract as that which the seamen had entered into in the case just cited contains an im *235 plied condition that the ship shall be seaworthy.” Mr. Brantly on page 70 of Law of Contracts, after referring to the other doctrine, says: “But the rule of other cases is that the promise is valid because the promisee is entitled to choose between the risk of being sued for a breach of his contract and the prospect of loss from going on at the original price. It also seems that the new promise of additional compensation amounts to a novation or a substituted contract. While a contract is executory on both sides, the parties are at liberty to rescind it by substituting a new one in its place.”
So without further citation of authorities we are of the opinion that the fifth prayer of the plaintiff was properly granted for reasons stated above. It follows that the first, second, fourth, sixth and seventh prayers of the defendant were properly rejected, as they in different forms present views contrary to the plaintiff’s prayer. The third was also properly rejected, as there was some evidence to prove the delivery of the materials. WTe see no error in admitting the evidence referred to in the first exception. Under the plaintiff’s theory he was to be paid the cost of making the cellar and the bills he paid or was liable for were admissible. The objection to the use of the bill of particulars was not well taken, but at any rate the subsequent agreement of counsel that the items set out in it appeared in the bills rendered by certain parties named relieved it of all question. It was a proper precaution for the protection of the defendants to see that such items were in the bill of particulars, and it was certainly proper for the plaintiff to show that items he was claiming payment for were there. We do not understand why the book of plaintiff mentioned in the third exception was objected to. He claimed to make the entries of payments by him in the book. If there could have been any injury by reason of the form of the question in the fourth bill of exceptions it was not answered, and another question was asked, which was not excepted to. It was certainly admissible to prove by the defendant, or any other witness, such deliveries of lumber, etc., as he knew of. The fifth and sixth exceptions to strike out *236 testimony were too general to inform us just what testimony was referred to, but we see no reason why such testimony as is mentioned in the latter part of those exceptions was not admissible. Payments had been made to the plaintiff from time to time and it was proper to show on what part of the work the money was paid, so as to enable the jury to determine what, if anything, was due on the work in controversy. Xhe testimony of Mr. Preston was relevant under our view of the law as announced above. Objection to that was presented by the seventh bill of exceptions. The eighth embraces a motion, made^at the conclusion of the testimony, to strike out all testimony tending to prove the making of a new promise, etc., which had been admitted subject to exception. After what we have said above, it is unnecessary to further consider that question. Finding no reversibie errors in any of the rulings, the judgment will be affirmed.
Judgment affirmed, the appellant to pay the costs.
