Bernard Corrigan & Co., a firm composed of Bernard Corrigan, Pat Dowling and George M. Garvey, in March, 1901, entered into a contract, with the Western Oklahoma Railroad Company, for the construction of one hundred and seventeen miles of railroad in the Indian Territory.
*138The contract stipulated that, in order to prevent disputes between the contracting parties concerning the provisions of the contract or the matter of performance thereof, “the chief engineer of the railroad company * * * shall be, and he is hereby, made, constituted and appointed the umpire to finally decide all such questions and matters; and he shall also determine and set forth in final estimates the quantity and classification and amount -due the contractor for all work and material furnished by the contractor under this contract,” and that his decision should in all things be final and conclusive upon the parties.
Bernard Corrigan & Company sublet the contract for clearing and grading sections sixty to sixty-seven, inclusive, to Carlile, Corrigan & Dunne, a firm composed of J. M. Carlile, Edward Corrigan and J. E. Dunne, at the following prices:
“Clearing and gruhbing, twenty-five dollars per acre.
“Earth excavation, thirteen cents per cubic yard.
“Loose rock excavation, thirty cents per cubic yard.
“Solid rock excavation, sixty cents per cubic yard.
“Granite excavation, one dollar per cubic yard.
“Overhaul, one and one-half cents per cubic yard, over 5000 feet.
“Riprap, one dollar per cubic yard.”
After the completion of the -whole work, George M. Garvey commenced a suit in the chancery court of Pulaski Gounty against his co-partners in the firm of Bernard Corrigan & Company to settle the affairs of .the partnership and to enjoin the railroad company from paying over any money to Bernard Corrigan.
Carlile, Corrigan & Dunne (the last-named member of the firm having died in the meantime and the interest of his estate in the contract being represented by his executrix, Llelen M. Dunne) intervened in the suit, claiming a balance of $6,513.66 to be due them by said principal contractors for work performed under the contract, and prayed that said amount due them should be decreed to them before the partnership fund under the contract of the court should be paid to Bernard Corrigan & Company, or any member thereof. The interveners alleged in their complaint that the contract between them and said principal contractors was verbal, that the work performed *139¡thereunder by them at the prices agreed upon' amounted in the ■aggregate to $59,439.10, and that they had been paid the sum of $52,925.44, leaving due them the said amount claimed as above stated.
Bernard Corrigan & Company, the defendants'to the intervention, filed their answer, setting forth the terms of their contract with the railroad company and alleging that the interveners, in their contract with the defendants, had agreed to perform all work undertaken by them under and subject to all the terms of said contract between defendants and the railroad company. They further alleged that the chief engineer of the railroad company made a final estimate of all the different kinds of work performed in said sections, that the railroad company had settled with them and paid them for the work in accordance with said final estimates, and that they, in turn, had settled with interveners and paid them in full for • all work performed, in accordance with said final estimates of the chief engineer. They denied that they were indebted to the interveners in any sum.
The interveners subsequently filed an amendment setting forth that Bernard Corrigan, one of the partners, promised in August, 1902, in writing, that, if there was any mistake or error in the account of Carlile, Corrigan & Dunne, the error should be corrected; that there was an error and a reclassification by the engineer of the railroad company, by which the principal contractors, Bernard Corrigan & Company, received pay for 9,292 cubic yards which had originally been classified as loose frock, and which was later classified as granite, amounting to $6,504.40, and that this change was made in work done by Carlile, Corrigan & Dunne; and demanding judgment for that amount additional.
The chancellor found against the interveners on the final hearing and entered a decree dismissing their complaint, and they appealed to this court.
The first issue of fact presented is whether or not, in the verbal contract between the interveners and defendants, the former were to be bound by the decision and final estimates of the chief engineer of the railroad company, according to the stipulations of the principal contract.
The testimony of several witnesses introduced by the de*140fendants showed that the contract was made with Mr. Dunne, acting for Carlile, Corrigan & Dunne, and tended to establish such .a stipulation in the contract. One of the witnesses, the bookkeeper for Bernard Corrigan & Company, testified positively that suóh was the agreement, and that a written contract was prepared as agreed upon, covering all the terms of the contract, and containing the stipulation, but that Mr. Dunne afterwards declined to sign it for the sole reason that it embraced more work than he was willing to undertake. He testified that the work was agreed to be done under the contract. There are some unsatisfactory features about the testimony of these witnesses, but the testimony is uncontradicted, and we can not :say that the chancellor erred in accepting it as true.
Mr. Dunne died before the intervention was filed, but the plaintiff Garvey testified that Carlile agreed that the final estimates of the chief engineer should govern. Carlile did not testify.
The agreement to abide by the decision and final estimates of the chief engineer is binding upon the parties and the decision of the engineer can not be questioned except by showing “fraud or such gross mistake as would necessarily imply bad faith or a failure to exercise an honest judgment.” Hot Springs Railway Co. v. Maher, 48 Ark. 522; Ozan Lumber Co. v. Haynes, 68 Ark. 185; Ark-Mo Zinc Co. v. Patterson, 79 Ark. 506, and cases cited.
The complaint of the interveners contains no allegation of fraud on the part of the chief engineer who classified the work and finally estimated it, nor is there any testimony tending to show fraud or mistake except the testimony as to the difference between his classification and those of the engineers subsequently employed by the interveners to examine the work. This is not sufficient to establish fraud or gross mistake, as, to make the most of it, the conflicting testimony leaves in doubt which of the estimates and classifications is correct,
The only remaining question, therefore, is whether or not appellants have been paid for their work in accordance with the final estimates of the chief engineer. The work was completed in May, 1902, and after the estimates and certificates of the chief engineer were furnished to Corrigan & Company, the *141principal contractors, the latter sent to appellants a final estimate or summary of the work done by them, showing a total of $52,925.44 price of work, previous payments $46,059.89, leaving $6,865.55 balance due. On June 30, 1902, they sent a check to appellants for this amount, and they now contend that this was all that was due appellants for work. They contend that the estimate .referred to above was in accord with the final certificate of the chief engineer, and that .the payment closed finally the. transactions between the parties. Appellants refused to accept the payment in full, but did receive and credit it on the amount due. It is conceded that when the work was completed the chief engineer based his estimate and certificate of appellants’ work upon reports and classifications of a subordinate engineer named Woods; that the sub-contractors expressed dissatisfaction with the classification, and another engineer named Board was sent to re-classify the work, and upon the latter’s report the chief engineer changed his classification of 9,292 cubic yards of loose rock into granite. This change was made in appellants’ work and, at seventy cents per yard, which was the difference- in the contract price between loose rock and granite excavation, made a difference of $6,504.40. The further question of fact at issue is whether this change was made before the payment of $6,865.55 or afterwards. If -afterwards, appellants are entitled to recover the additional amount shown to be due in accordance with the change in the final estimate of the chief engineer, for he was, as we have .already seen, the final arbiter of the difference between the parties.
We have already called attention to the fact .that -the check for this payment was dated June 30, 1902, and the estimate which accompanied • it, though not dated on its 'face, mu-st have been of that or prior date as the balance shown thereby to be due corresponds exactly with the amount of the check. The only testimony in the record which throws any light on this point is that of Bernard Corrigan, one of the appellees. His examination concerning the estimate which accompanied the check, and which is -designated in .the records as Exhibit No. 4 to the deposition of witness Donnelly, is as follows: Q. “Is that estimate or statement the one upon which you settle with Carlile, Corrigan & Dunne?” A. “I would not say from recol*142lection, but to the best of my opinion it is.” Q. “Now, do you know whether that was made out and furnished to Carlile, Corrigan & Dunne, when they got through with their work there, and before the chief engineer had made the changes from loose rock to solid rock granite, which appears in his final estimate?” A. “The first estimate was made on a classification made by Mr. Woods; then Mr. Moliter sent Mr. Beard over the work, at my request, and Mr. Beard, as I remember, raised the estimate in dollars and cents some five or six thousand.” Q. “I call your attention to a notation on the margin of Exhibit No. 4, which Miss Dunne, in her deposition, says was made by her; do you know anything about the matter referred to. in that notation?” A. “The matter referred to in that notation is the difference in the number 'of yards of loose rock, under Mr. Woods’s estimate and in Mr. Beard’s final estimate. On examining this notation and this exhibit, I am satisfied that it was made and furnished to the sub-contractors before the final estimate of the chief engineer was made and before the chief engineer made the change at my request, which I have spoken of, changing loose .rock to solid rock granite.”
In another deposition he stated that the final estimates of the chief engineer were furnished by them (the principal contractors) in July, 1902, probably about the 22d of that month. It is true that he states in general terms that he settled with appellants according to the final certificate of the chief engineer, but these specific statements in his testimony show that that was not true. If the change in the classification from loose rock to granite was made in July, and after the estimate which accompanied the check was made and delivered to appellants, it necessarily follows that appellants have not been paid for the difference on the second classification, and are entitled to recover it. There is no dispute about the amount, or that the reclassification was as to appellants’'work. The only question is whether the settlement represented by the check dated June 30, 1902, included the additional sum due by reason of the reclassification. We think from the evidence that it was not included. The chancellor erred in his finding on this point.
The decree is therefore reversed, and the cause remanded with directions to enter a decree in favor of the interveners for $6,504.40, with interest from date of filing of the intervention.
