Opinion bv
Mr. Justice Bbown,This suit was brought upon a written contract. In its statement filed, the appellee sets forth that the defendants, on or about July 8, 1896, had entered into an agreement with it, in writing, for the purchase of four stokers, and a copy of the alleged contract was attached to and made part of the statement. .In their affidavit of defense, the defendants specifically denied that they had ever executed any such contract as was declared upon and set forth totidem verbis in the statement. With notice so given to it by the defendants in their affidavit of defense, as.well as by their plea, the plaintiff pro*510ceeded to try and offered in evidence, under objection, as tbe basis of its claim, an agreement different in terms from that declared upon. It seems that one Persch had taken to the defendants a specification and proposal, signed by the plaintiff, for the erection of the stokers, to which he had attached certain modifications of the terms. The appellee admits that he was its selling agent, and that it was bound by whatever he did in taking the order. The specification and proposal of the plaintiff, as modified by Persch, were left with the defendants, who handed him their acceptance of the same. In bringing suit, the appellee set forth its contract in writing to have been on a specification and proposal, of which it had retained a copy, but it was notified by the affidavit of defense that the contract or agreement, as set forth by it in the statement, was not the one that the defendants had signed.
Upon the trial, the defendants, in pursuance of notice from the plaintiff, produced the real contract that they had entered into, and the court, under objection, allowed the specification and proposal so produced to be received in evidence, with the modifications, made and attached to them by Persch, separated from them. The specification and proposal annexed to and made part of the statement were materially different from those produced by the defendants and offered in evidence in the first instance by the plaintiff. According to the statement filed, the specification and proposal provided: “We will furnish you a competent engineer to superintend the erection of the stokers and to instruct your fireman in the use of the same, for which you will pay four dollars per day, cost of board, and traveling expenses.” The specification and proposal submitted to the defendants provided: “We will furnish you a competent engineer to superintend the erection of the stokers and to instruct your fireman in the use of the same.” The difference between these two clauses is manifest. The terms of payment, according to the specification and proposal declared on, were one half cash on presentation of bill of lading and invoice, or when ready for delivery on contract, balance in sixty days from date of shipment. The specification and proposal accepted by the defendants provided that payment was to be made when the guarantees of the plaintiff were carried out in, say, six months. These are material differences between the specification and *511proposal as declared upon and proved on the trial, under objection by the defendants. But still more material is the variance between the contract declared upon and the one left with the defendants by Persch and signed by them. It provided that the price “ complete ” should be only $2,000, instead of $8,500, as set forth in the statement and made part thereof.
Under these material variances, the objection made by the defendants to the admission of the written contract, as produced by them on the trial, in pursuance of notice, and offered in evidence by the plaintiff, should have been sustained, for the latter was seeking to recover, according to its statement, upon one contract, which it alleged it had made with the defendants, while it relied, before the court and jury, upon another. When the plaintiff closed its testimony, the defendants were justified in asking the court to say that, as they had been sued upon a contract which had not been made by them, there could be no recovery, and judgment of nonsuit ought to be entered. This application was denied, and the appellants proceeded with their defense. In making the same, it is true that they did offer in evidence the real contract entered into, but plaintiff cannot take advantage of what they did, when it was simply to prove that they had not contracted as set forth in the pleadings. In other words, their offer of the real contract was simply consistent with their plea and affidavit of defense, that they had never contracted with the plaintiff as set forth in the statement. When all the evidence and the whole of the real contract was before the court, the defendants were again justified in asking that the jury be instructed to render a verdict in their favor. If such directions had been given by the court, the finding of the jury would not be disturbed.
It is true that pleading has, in late years, been greatly simplified, but it has not become so simple that a plaintiff, seeldng to recover upon a written contract, which is in existence, can declare upon a different one; and a defendant still has a right to know just what the cause of action is. The Procedure Act of May 25, 1887, P. L. 271, provides that the plaintiff’s declaration shall be accompanied by a copy of the contract sued upon. The statement in the case before us contains no such copy. If, as a matter of fact, the defendants ought to pay the sum of money which the jury found they owed the plaintiff, we cannot *512sustain their finding, because the trial was not an orderly one. Allegations and proofs must still correspond. The wise and reasonable requirement that a plaintiff must correctly and accurately set forth the material grounds of his complaint has, with us, withstood the reforming hand of the modern pleader, and .the defendant yet knows that he need answer only what is charged against him. In apparent disregard of this, the plaintiff in the case before us, when confronted with the real contract entered into with the defendants, was, in the face of objection, promptly made, allowed to proceed, without amendment of its pleadings, to recover upon a different one. We cannot sanction a judgment so recovered. We might properly reverse it, without giving the plaintiff an opportunity to try its case under pleadings corresponding to its proofs, but we will award a new trial, that, under amended pleadings, a just verdict may be rendered. There is nothing else in the record requiring our attention.
Judgment reversed and new trial awarded.
