delivered the opinion of the Court.
The Davis Sewing Machine Company, a corporation, of the first part, and John C. Foote, of the second part, made an agreement in writing. We will quote some passages from it. It stated: “That the said party of the first part has this day appointed the said party of the second part its authorized agent for the sale of the Davis Sewing Machines, which sewing machines shall be consigned to him by the said party of the first part; and for the further purpose of collecting and remitting cash, notes and mortgage leases received from the sale of such machines ; and for the further purpose of caring for, holding and storing such machines as are hereinafter specified, and for no other purpose whatever. The territory in which said sales and leases of said Davis Sewing Machines may be made by said party of the second part under this contract, is Baltimore County, in the State of Maryland.” It contained the following among other stipulations : “ Second. Said party of the second part shall continuously devote his entire time, skill, and best efforts to the vigorous prosecution of the business of selling and leasing said sewing machines in all parts of said territory, so that in every part of the same said business shall be continuously and vigorously prosecuted by the party of the second part.” There are a number of clauses relating to the manner of transacting the business, collecting and paying over money and other details. Theviews which we have taken of this case make it unnecessary to refer to them more particularly. At the time this agreement was made, Plunkett, *532the appellant; by a contract in writing made with the Machine Company guaranteed the performance by Foote of all the engagements contained in the agreement above mentioned, including the payment of all indebtedness to the Machine Company, which might be incurred by him. The guaranty contained the following clause : “ The within contract -may be varied or modified as to terms, prices or territory, by the mutual agreement in writing of said Davis Sewing Machine Co., through its secretary, and John C. Foote, without in any way impairing or affecting my liability on this guaranty.” An action at law was brought on the guaranty by the Machine Company against Plunkett, and a judgment was obtained against him.
■ The evidence tended to show that Foote had made default in several particulars and that he was indebted to the Machine Company in the sum of about five hundred dollars : also that the said company had enlarged the territory within which he was .to exercise his agency ; and that in addition to sending to him the Davis Sewing Machines, had sent him other machines of a different make, some of which were of a lower price and inferior quality and did not give satisfaction to customers; and also that no agreement in writing had been made between Foote and the company (as it is expressed in the bill of exceptions) for a “ variation or modification of the territory of his agency.” The record does not state in how many places beyond the limits of Baltimore County Foote was authorized to act. as agent for the company. It is very certain, however, that his responsibilities were materially enlarged by an extension of the territory within which he was to act. A more onerous duty was imposed upon him, the purpose of which was that he should become responsible for his dealings with a greater number of machines, and necessarily for the collection and payment of a larger amount of money. These changes were inconsistent with the duties which by the written contract he agreed to perform. It was impossible for him (as he agreed by the second stipulation already quoted) to “ devote his *533entire time and skill and best efforts to the prosecution of the business ” within the limits of Baltimore County. This obligation was eliminated from his contract with the Machine Company ; and in the place of it, another one was substituted which required skill, diligence and fidelity in a greater number of transactions, and throughout a larger extent of territory.
Plunkett, by his guaranty, agreed to become responsible for every failure of duty on the part of Foote in all cases embraced by the terms of his written contract. But he was not bound to anything beyond its terms, interpreted according to their intent and true meaning. The liability of a surety or guarantor is created entirely by his contract; it is therefore strictly confined and limited to his contract. It is not a question whether he will be injured or benefited much or little by a change in its terms. No change can be made in them without his consent. All Courts have maintained that his responsibility cannot be extended by construction beyond the limits which he has himself fixed. In Miller v. Stewart, 9 Wheaton, 680, where a bond was given, conditioned for the faithful performance of the duties of the office of deputy collector of direct taxes for eight certain townships, and the instrument of the appointment, referred to in the bond, was afterwards altered so as to extend to another township, without the consent of the sureties, it was held that the surety was discharged from his responsibility for moneys subsequently collected by his principal. It will be seen that the Court decided that the extension of the appointment to the ninth district, was, in effect, an extinguishment of the appointment for the eight districts, and was a new appointment for the nine, and that the obligation of the surety did not apply to the new appointment. In United States v. Kirkpatrick, 9 Wheaton, 720, it was held as follows : “ A bond, given on the 4th of December, 1813, for the faithful discharge of the duties of his office, by a collector of direct taxes and internal duties, appointed (under the Act of the 22d of July, 1813, *534ch. 16.,) by the President, on the nth of November, 1813, to hold his office until the end of the next session of the Senate, and no longer, and subsequently appointed by the President,' with the advice and consent of the Senate, on the 24th of January, 1814, is to be restricted (as to the liability of the sureties) to the duties and obligations created by the collection Acts passed antecedent to the date of the bond. The second commission, issued under the appointment, with the advice and consent of the Senate, operates a revocation of the first commission, issued under the appointment by the President, which was to continue until the end of the next session of the Senate, and no longer ; and the liability of the sureties in the bond did not extend beyond the duration of the first commission.”
(Decided January 5th, 1897).In the case now before us the original agreement between the Machine Company and Foote was changed, and the effect was to make a new agreement with new terms substituted in the place of those which had been abandoned. By the contract of guaranty this might be done by mutual agreement in writing between the company and Foote; but no other way was provided for doing it. The evidence in the cause was that no such agreement had been made.
The proof tends to show somewhat vaguely that the change was made in March, eighteen hundred and ninetyThrée, and that the defaults for which this suit is brought occurred after that time. If this be so, the plaintiff has no right of recovery. Of course, the question ought to be submitted to a jury; or, in this case, to the Court sitting as a jury. Construing the third prayer of the defendant in connection with the evidence, we suppose that this is what it means, although it might have been more distinct. With this understanding of it we think that it ought to have been granted. The other prayers were properly rejected.
For error in the rejection of the defendant’s third prayer the judgment must be reversed.
Reversed and new trial.
