Appellant, Evelyn W. Daugherty, and appellee Godfrey W. Merrifield were formerly husband and wife and appellee, J. B. Lambert, is now, and has been for the past several years, the business partner of Merrifield.
This suit was instituted by appellant in the Phillips Circuit Court against appellees, alleging a balance due as evidenced by a promissory note of date October 1, 1927, due and payable six years after date, drawing interest from date until paid at the rate of 7 per cent, per annum, of $2,000, together with $211 accrued interest thereon.
Appellees answered the complaint thus filed by admitting the execution of the note sued upon and affirmatively pleading the release and satisfaction thereof by an agreement of date June 12, 1929. A cross-complaint was also filed by appellees against appellant, alleging that under a mistake of fact they had wrongfully paid appel*538lant upon said note the sum of $525.90, for which they prayed judgment.
The agreement plead by appellees as a release and satisfaction of said note is as follows :

Appellant filed an answer to appellees’ cross-complaint in which she admitted the payments on the note by appellees, but denied that they were made or paid under misapprehension of the facts, and she denied that the contract of June 12, 1929, had reference or relation to the debt as evidenced by the note in suit-; she denied that Lambert was either a party or privy to the contract of June 12,1929.
By way of amendment to their answer, appellees pleaded as res judicata certain litigations theretofore determined between appellant and appellee, Merrifield, in the chancery court of Phillips County.
The testimony on behalf of appellant tended to show that the debt evidenced by the note sued upon ,was not released or satisfied by the agreement of June 12, 1929; that certain payments had been made thereon subsequent to the execution of said contract,, and a letter was introduced which was admittedly written by appellees in reference to this debt as follows:
“September 29,1933.
“Mr. F. J. Daugherty, Oakland Avenue, Helena, Arkansas.
*541“Dear Sir:
“We have your letter reminding us that on October 1, there will be due a note of ours, together with one year’s interest, and that you expect the prompt payment of this indebtedness. We would like very much to be able to pay this amount due you at this time, but, like most other people, we find this impossible. We cannot refinance the mortgage, and we do not have the available money to pay it.
“By straining a point we can pay the interest due of $140 with the promise that we will make monthly payments on the principal in as large amounts as we can, so as to make some reduction in that amount during the coming year. Under this arrangement we would expect the note to be carried past due for a year, in which time we hope to be able to either refinance it or pay it off.
“If this arrangement is satisfactory, please advise us and we will forward the interest check promptly on the due date of the note.
“Yours very truly,
‘ ‘ Merrifield & Lambert,
‘ ‘ By J. B. Lambert. ’ ’
The testimony on behalf of appellees tended to show that the payments made by appellees upon the note in suit and the letter written by them, heretofore quoted, were effected under a misapprehension of facts in this: That appellees had misplaced the contract of June .12, 1929, and were unable to locate it at the time said payments were made and at the time said letter was written, and that they were apprehensive of results were they to antagonize appellant by denying liability on the note. Other testimony was adduced by the respective parties, but it is deemed unnecessary to summarize it here. At the conclusion of the testimony, appellant requested the court to direct the jury to return a verdict in her behalf for the amount sued for. This request was refused by the trial court, and this is the paramount issue presented on this appeal. The trial court submitted the issue of release and satisfaction and the issue of wrongful payments by appellees upon the note to appellant as set *542forth in the cross-complaint, and the jury decided these issues in favor of appellees, and appellant appeals.
When appellees admitted the execution of the note in suit, the burden then shifted to and devolved upon them to show discharge or satisfaction of the note. Continental Gin Co. v. Benton, 104 Ark. 367, 149 S. W. 528; Hays v. Dickey, 67 Ark. 169, 53 S. W. 887; Blass v. Lawhorn, 64 Ark. 466, 42 S. W. 1068.
To discharge this burden of proof of release and satisfaction, the contract of June 12, 1929, was introduced in testimony, together with appellees’ admitted letter of September 29, 1933, in reference to this debt. These instruments constituted the written contract between appellant and appellees in reference to the release and satisfaction of said debt or note. Under the law, it ivas the imperative duty of the trial court to construe these instruments and declare their effect instead of submitting their construction and effect to the jury for their interpretation and construction, there being no ambiguity in said instruments. Pine Bluff, Sheridan & So. Ry. Co. v. Leatherwood, 117 Ark. 524, 175 S. W. 1184; and Elliott on Contracts, page 775.
We think the fair, reasonable and only construction to be placed upon the contract of June 12, 1929, and appellees’ admitted letter of September 29, 1933, is that the debt evidenced by the note in this suit was neither released nor satisfied by the contract of June 12, 1929, and that the letter of September 29, 1933, is an unequivocal acknowledgment by appellees that this debt ivas not released or satisfied 'by said contract, and that the trial court should have so construed said instruments, instead of submitting their construction and interpretation to the jury. Citizens’ Bank & Trust Co. v. Hinckle, 126 Ark. 266, 189 S. W. 679; and Arkansas Fertilizer Co. v. Banks, 95 Ark. 86, 128 S. W. 566.
True, appellees testified that they had misplaced their copy of the contract of June 12, .1929, at the time they wrote this letter to appellant, but they do not say, and nowhere contend, that they did not know of its execution and contents at the time. Admittedly, when appellees found their copy of this contract, it apprised them *543of nothing they did not know when they made the payments on the note and wrote the letter in reference thereto.
Appellees also contend that this case should be affirmed because of their plea of res judicata-. This plea is predicated upon a suit between appellant and her former husband, Merrifield, wherein appellant, by equitable proceedings, sought discovery and accounting against her former husband of and for $56,300, which had passed through Merrifield’s hand as husband and agent of appellant. The note here sued upon does not appear to have been an issue in said suit or had any part in the proceedings. Moreover, just why appellant should litigate in reference to a note which was executed and delivered to her more than two years prior to the litigation does not appear from this record. Certainly no suit or proceedings for discovery and accounting could aid or assist appellant in discovering this note because it was then, and had been at all times since its execution, in her possession and control. Again, this note was not due and did not mature until October, 1933, or more than four years subsequent to the suit pleaded as res judicata, and there could have been no reason for litigating said note in that proceeding.
We conclude that the suit pleaded as res judicata had no reference to or connection with the note here sued upon. This note was not within the issues in the suit for discovery and accounting, and is therefore no adjudication of appellees’ liability thereon. Hannah v. Carrington, 18 Ark. 85; Shall v. Biscoe, 18 Ark. 142; McCombs v. Walls, 66 Ark. 336, 50 S. W. 876; Fagel v. Butler, 96 Ark. 87, 131 S. W. 211; Fourche River Lbr. Co. v. Walker, 96 Ark. 540, 132 S. W. 451; Pulaski County v. Hill, 97 Ark. 450, 134 S. W. 973; Sauls v. Sherrick, 121 Ark. 594, 182 S. W. 269; and McWharter v. Andrews, 53 Ark. 307, 12 S. W. 1099.
There is no controverted question of fact in reference to release and satisfaction of the note in this suit, and the trial court erred in submitting this issue to the jury, and likewise erred in refusing to direct a verdict in favor of appellant for the amount sued for.
*544The cause is reversed and remanded with directions to proceed in conformity to this opinion.
