On the 15th day of July, 1912, R. L. Bibb, of Little Rook, Arkansas, and the Merrimac Manufacturing Company, of New York City, entered into a written contract, whereby the former agreed to travel for the latter, iand to devote his entire time, zeal and energy toward selling its goods in the States of Arkansas and Missouri, and to carry no side line whatever. The Merrimac Manufacturing Company agreed to pay Bibb a commission of 10 per cent on all accepted orders, including mail orders, ■ — house sales coming from his territory; the company further agreed to pay him 5 per cent, of all accepted orders, and to notify him of all declined orders within thirty days after the receipt of same. The company also agreed to continue the contract at the expiration of the first season, provided Bibb had sold $20,000 worth of goods for the fall season of 1912 and spring season of 1913. Bibb instituted this suit to recover commissions alleged to be due him, and writs of garnishment were issued against certain residents of the State of Arkansas who are alleged to be indebted to the defendant company.
R. L. Bibb testified substantially as follows: I commenced to sell goods for the Merrimac Manufacturing *446•Company, under a contract which is the foundation of this action, in the fall of 1912, and continued as such salesman during the spring season of 1913; during the spring of 1913, the ¡company failed to send me 5 per cent, on accepted orders, as provided in the contract, and failed to notify me within thirty days of the declination of any order. Under the contract, they were to pay me for all orders accepted coming from my territory, hut one of their representatives came into my territory and sold goods without my consent, and they refused to pay me a commission on the same. They are indebted to me in the sum of something over $2,500.
Evidence introduced on the part of the defendant company is substantially ¡as follows: The Merrimac Manufacturing Company is a partnership composed of Morris Marks and Aaron M. Marks; the company is engaged in the manufacture and sale of clothing in the city of New York; during the spring of 1913 the plaintiff, without the consent of the defendants, sold clothing for another firm as a side line. The company admitted that one of their representatives sold goods in certain described territory in the State of Arkansas, but said it was with the consent of the plaintiff, because he could not make all of the territory. The company filed an itemized account of all the sales made by the plaintiff, and stated that they had paid him all the commissions due him.
In rebuttal the plaintiff testified that he carried a side line which consisted of pawn-broker’s goods, overcoats and pants, and stated that he did this because the defendants refused to pay Mm the commission due him under the contract, and that he was unable to pay his traveling expenses without carrying this side line. He further testified that he devoted all the time he could to the defendant’s business, and never tried to sell goods for the other firm he represented until he had first worked each point for the defendants. TMs side line, he said, did not conflict with the line he carried for the defendants, but rather did it good.
*447The jury .returned a verdict for the plaintiff, and from the judgment rendered, the defendants have appealed.
The defendants saved their exceptions to the testimony of the plaintiff to the effect that the side line carried Iby him did not conflict with his sale of the line of goods carried for the defendants, but rather laided it, and assigned as error the action of the court in . admitting this testimony. In this’'contention we think 'counsel for the de: fendants are correct. Counsel for the plaintiff seeks to uphold the action of the court upon the authority of Fitzgerald v. LaPorte, 64 Ark. 34, and Mitchell v. Caplinger, 97 Ark. 278, and other cases of a like character.
In those cases the court held that a substantial performance is all that is required to authorize a recovery under a contract, the additional cost of a literal compliance with the contract being taken into consideration in assessing damages. We do not think those cases have any application to the facts of the present case. It is true, the plaintiff testified that he used iall reasonable means and diligence to further the interests of the defendants; hut the contract, by its express terms, provided that the plaintiff should not carry any side line, and it is the duty of courts to enforce contracts according to their terms.
(1) According to the undisputed testimony, the defendants were engaged in the manufacture and sale of clothing; the side line carried by the plaintiff 'also consisted of clothing. It is true this side’ line consisted of clothing purchased at a pawn-broker’s shop, but the testimony of the defendants tended to show that this side line conflicted with plaintiff’s duties under their contract. But be that as it may, the contract, as we have already §een, in express terms provided that the plaintiff should not carry any side line during the time he worked for the defendants, 'and the carrying of a side line was in plain violation of the terms of the contract.
We think the admission of the testimony to the effect that the side line did not conflict with- plaintiff’s duties under the contract was prejudicial to the rights of the de*448fendants. This is emphasized by an instruction given by the court, which is as follows:
“I instruct you that if you find from all the evidence in the case that the plaintiff violated his contract by carrying side lines, or was selling goods for ¡another house, it would preclude ¡him from recovery in this case, unless you should further find that the defendant first violated its contract by not making payments ¡as called for in the contract. If you should so find, then the defendant can not complain of the plaintiff’s breach of contract, and the plaintiff should recover any amount you may find to be due him as unpaid commissions.”
It will be remembered that the plaintiff claimed certain-amounts due him as commissions for selling defendant’s -goods under the contract. The defendants denied that they owed the plaintiff anything. The instruction in effect tells the jury that if they should find that the defendants first violated the contract by not making payments as provided for therein, that they could not then complain of 'any breach of the contract by the plaintiff, and that the latter would be entitled to recover any amount due him as unpaid commissions.
(2) Of course, if the defendants had first committed a breach of the contract, they had no right to suppose that plaintiff, by thereafter performing the contract on his part, waived -any breach of the contract on their part. In such case, the plaintiff would have had the right to continue the performance of the contract -according to its terms and might have maintained an action against the defendants for the whole amount of the commissions due him; or, he might have treated the refusal of the defendants to pay him the commissions provided for in the contract as a manifestation of an intention on their part not to perform the contract -according to its terms, and sued, not only for the commissions ¡already earned by him under the contract, but 'also'for such commissions as he would have earned thereafter. See Spencer Medicine Co. v. Hall, 78 Ark. 336.
*449 (3) The fact that the defendants first- committed a breach of the contract would not entitle the plaintiff to recover the whole of the amount of the commissions provided for in the contract regardless of the fact as to whether or not he himself committed a breach of the contract.
Counsel for the defendants also assign as error the action of the court in refusing to give instruction numbered 2, asked for by .them. That instruction is as follows :
“The jury are instructed that if you find from the evidence that the plaintiff entered into a contract with the defendant company to work for them in the capacity of salesman, 'and agreed to devote his entire time and attention to the selling of defendant’s goods and wares and -agreed to carry no side line, and that in violation of the terms of said contract the plaintiff sold goods for other parties, and did carry a -side line, then this would-be a breach of the contract, and your verdict will be for the defendant unless you find they ¡knew of such breach and acquiesced therein. ”
(4) The court properly refused to give this instruction. It made the right of the plaintiff to recover anything depend upon whether or not the defendants knew that the plaintiff had committed a breach of the contract by carrying a side line. ' The contract, by its express terms, provided that the plaintiff should not carry a side line, iand the plaintiff committed a breach thereof by doing so. Notwithstanding this, he was entitled to recover commissions on all orders sent in by himself and accepted by the company, but was not entitled to recover on mail orders or orders sent in by -other representatives of the company traveling in the same territory.
(5) It is also contended by counsel for the defendants that the court erred in refusing to quash the service of summons on the defendants. We need not consider that, however, because the defendants, by appealing from the judgment rendered -against them -are now in court, and no further .service on them is required. Beal-Doyle *450 Dry Goods Co., v. Odd Fellows Building Co., 109 Ark. 77; W. T. Adams Machine Co. v. Castleberry, 84 Ark. 573; Holloway v. Holloway, 85 Ark. 431.
For .the error in admitting the testimony of the plaintiff to the effect that the side line carried 'by him did not conflict with his duties to the defendants, hut rather did them good, the judgment is reversed and the cause remanded.
