Appellant is a corporation engaged in the lumber business in the city of Memphis. Appellees are engaged in the business of manufacturing lumber for sale at or near the town of Hughes, in St. Francis County, Arkansas. Appellees had a large quantity of lumber stacked on their yard, and they entered into a written contract with appellant whereby appellant was ■ authorized to sell lumber on the market, at prices to be approved by appellees, for a commission of ten per cent.' upon the prices received. ' The contract described the lumber as 200,000 feet of lumber bulked down at Hughes, St. Francis County, State of Arkansas, and also about 500,000 feet of lumber ‘‘now on sticks on , the mill yard of first party, about six miles south of Hughes.” The contract recites that, in consideration of its execution, appellant agreed to advance to appel-lees as a loan the sum of $4,000, to be evidenced by note due April 6, 1921, bearing interest; and it further recites that “it is mutually agreed that first party (appel-lees) hereby gives the second party (appellant) the exclusive sales agency or right to sell certain lumber described as follows, to-wit.” The contract does not expressly name a date for its expiration, nor a definite time limit, but it provides that appellant should sell, without reasonable delay, “market conditions considered, all of the above described lumber, 'as soon as he can obtain orders therefor, said lumber to be sold upon orders at such prices as are approved by first party.” There are further provisions in the contract to the effect that sales *433of lumber should be credited on the said note of appel-lees until the same be-paid, and that thereafter the net proceeds of sales be remitted to appellees. The contract also provides that appellant will guarantee payment on all lumber sold.
This action was instituted by appellant against ap-pellees to recover damages for breach of the contract. It is alleged that, after a certain- amount of lumber was shipped and sold and applied on the debt of appellees to appellant, appellees refused to ship any more lumber. The action is to recover commissions which would have been earned on the sale of the remainder of the lumber. The contract was exhibited with the complaint.
Appellees answered, denying all the allegations of the complaint, and/upon the issues formed, there was a trial, and testimony was introduced by appellant, but the court gave a peremptory instruction in favor of appel-lees, and judgment was accordingly rendered against appellant.
Counsel for appellees defend the judgment on the ground that the authority conferred on appellant in the contract was revocable, and that it constituted ho breach of the contract to revoke it by a sale of the remainder of the lumber to other parties.
The contract, in express terms, confers an exclusive agency to sell, but it is contended that even this feature of the contract does not render it irrevocable unless a time’ limit is fixed for performance, or the authority is coupled with an interest.
It is conceded to be the rule that, where authority as an agent is not coupled with an interest, nor created for a definite period, it is terminable at the will of the principal. 2 C. J., pages 533, 534; 1 Mechem on Agency, § 570.
Counsel on each side argue with much zeal the question as to what constitutes a consideration or an interest coupled with the authority, but we have concluded that this case can be determined upon the question that a *434definite time was fixed in the contract for its performance. It is not required that the time of performance be fixed in express words, but, if the necessary result of the authority given is to fix a period for its exercise, then the contract, which is, in terms, exclusive, cannot be revoked. Our conclusion is that this contract, by its own terms, fixes a time within which it must be performed. In the first place, the subject-matter of the contract is merchantable chattels, which, according to the terms of the contract, are to be expeditiously and without unreasonable delay sold upon the market. This contemplates an immediate and continuous effort to sell the property on the market, and the language can only be construed to mean that it should extend until the property should be sold. The timo of performance is not fixed in days and months, but it is ascertainable from the terms specified in the writing. In other words, the contract does not itself specify the time for its performance, but it furnishes the means for its ascertainment, that is, say, an opportunity to sell on the market within a reasonable time. We are of opinion therefore that the contract is valid, and that a sale to another party by appellees, within the time afforded under the contract to appellant to make sale, constituted a breach of the contract, for which appellant was entitled to recover commissions.
Of course, the question whether or not appellant proceeded expeditiously towards the sale of the lumber, or whether there was an unreasonable delay, are questions nf fact to be determined ’by a trial jury. This was taken away from the jury by the court’s peremptory instruction.
There is another feature of the case which should be mentioned, and that is, the interpretation of the following language of the contract: “Second party agrees to sell, without reasonable delay, market conditions considered, all of the above described luftiber as soon as he can obtain orders therefor, said lumber to be sold *435upon orders at such prices as are approved by first party.”
The use of the word “reasonable” is an obvious error, as it is evident that the word “unreasonable” was intended. In disposing- of the case we have treated the contract as if it read “without unreasonable delay.”
The judgment is therefore reversed, and the cause remanded for a new trial.
