(after stating the facts). When the plaintiffs had drilled the first well under the original contract to a depth of 1,538 feet, the log kept by them contained this notation, “well is showing oil and gas very heavy.” According to the evidence for the plaintiffs, they reported this fact to a representative *412of the defendant, who was on the ground, and received orders to shut down and wait for the casing which was to be furnished by the defendants in making a test for- oil and gas. The log shows that the plaintiffs next began to' drill on October 10, 1921. They say that the defendants failed and refused to furnish the casing with which to make the test.
On the other hand, according to the evidence, for the defendants, the failure to make the test was due to the action of the plaintiffs.
The view we have taken of the matter renders- it unnecessary for us to decide this question. The parties compromised their differences in this respect by the execution of the supplemental agreement of November 12, 1921. This agreement expressly recites that it is a part of the original contract dated the 6th day of September, 1921. It also recites that the nature of the agreement is such that the parties of the second part of the original agreement have failed to comply with the terms of their contract for the testing of the structures as called for in their 'Contract for the drilling of the well, and that they agree- to allow the parties of the first part to take over their drilling machinery and equipment for the purpose of drilling a new well and making a complete test at the depth of approximately 1,550' feet.- ■
'The contract further provides that the parties of the first part -shall have full possession of the equipment and shall move the derrick and machinery and charge the cost of moving it to the parties of the second part.
Thus it will be seen that the supplemental agreement by its express terms modifies the original agreement. In - it the parties of the second part recognize that they have failed to make the test required in drilling the first, well and agree to turn .over their drilling machinery and equipment to the parties of the first part to drill a new well in order that proper tests may 'be made for oil and . gas as the drilling progresses.
The new well was to be drilled by the parties of the first part of-the depth of 1,550 feet. This showed that *413the new well was to be tested at this depth by the parties of the first part for oil and gas. The supplemental agreement imposed new conditions upon the parties to the original agreement, and modified it to the extent that the provisions of the original agreement were changed by those of the supplemental agreement.
The contract when changed by the mutual consent of the parties became a new contract and took the place of the old one in so far as the terms are. inconsistent. In other words, the new contract supersedes or modifies the old one to the extent that their terms are inconsistent. Ozark & Cherokee Cent. Ry. Co. v. Ferguson, 92 Ark. 254; Murray v. Miller, 112 Ark. 227, Weaver v. Emerson-Brantingham Imp. Co., 146 Ark. 379.
It follows that the defendants by making the supplemental agreement with the plaintiffs lost all right to rely upon the first contract either to enforce it as a contract, or to rely upon it in a suit for damages for a breach thereof to the extent that the first contract was changed or modified by the supplemental contract. It has been well said that when a new contract is inconsistent with and renders the performance of a former one between the same parties impossible, the former is rescinded upon the same principle that a subsequent act of the Legislature repeals a former act, when the two are inconsistent. Paul v. Meservey, 58 Me. 419.
It follows that a waiver of performance under the first contract arose when the supplemental contract was entered into in so far as the test provided for in drilling the first well is concerned.
This brings us to a consideration of the statement of the accounts between the parties. The supplemental contract of November 12, Í921, provides that the parties of the first part shall pay the parties of the second part all moneys which may be due them under their original contract after the cost of the second well has been deducted.
Under the terms of the original contract the parties of the first part agreed to pay the parties of the second *414part the sum of $50 per month, for the time the drilling crew was in operation, for a man to pump water. This service was performed for about two months, and the chancellor properly allowed the plaintiffs one hundred dollars for the services of a water pumper. The contract price of the well under the original contract was $15,000, and the chancellor’ properly allowed this sum, less the ' cost of drilling the second well. The chancellor allowed the- defendants $2,000 for drilling the second well.
G-. A. Woods and A. S. Woods both testified that this was a reasonable sum' for the cost ■ of the second well. They were corroborated by the testimony of three disinterested drilling contractors, who testified that the well could have been drilled in from ten to twenty days at most, and that $2,000 was a reasonable sum for the cost of drilling it.
According to the testimony of J. W. Jolly, who was in complete charge of drilling the second well, he did not commence it until after January 6, 1922, and completed it by the second day of February, 1922.
While the defendants submitted an expense account much larger than the sum of $2,000, we think that the decision of the chancellor was correct ini only allowing that sum. It must be remembered that'the defendants were not to receive any profit for drilling the second well, but were only allowed the cost of drilling it. The ' drilling outfit belonged to the plaintiffs, and the wear and tear on it was very great. Hence drilling contractors were usually allowed a large profit for drilling wells when they supplied their own drilling machinery and equipment. In fixing the price to be paid the plaintffs for drilling the first well, the profits were included. In determining what the profits were, of course their services, the rental value of the drilling outfit, and the wear and tear on the machinery would all be estimated.
We are of the opinion that, when all the testimony is considered, the chancellor did not err in finding that $2,000 was the actual cost of drilling the second well to the depth of 1,550 feet.'
*415The chancellor also allowed the plaintiffs the sum of $1,350 for the rent of their drilling outfit in order to enable the defendants to drill the well deeper than provided for in the first contract.
When the two contracts of the elate of November 12, 1921, were executed one of them provided that the defendants had rented from, the plaintiffs their complete drilling outfit for the purpose of drilling a test well for oil and gas below the depth provided in the first contract, and as rent they agreed to pay $25 per day for the drilling outfit. The defendants took charge of the drilling outfit of the plaintiffs when this contract was executed on the 12th day of November, 1921, and used it in drilling the first well deeper until the 6th day of January, 1922. Therefore, the chancellor properly allowed the sum of $1,350 for the rent of the drilling outfit under this contract.
The chancellor also allowed the plaintiffs $1,950 for damages on account of the defendants unlawfully detaining their drilling equipment, under the supplemental contract. The drilling of the second well was completed on the 26th day of April, 1922. There was no showing of oil or gas at the depth drilled. On the 5th day of-May, 192'2, the plaintiffs made a demand in writing .of the 'defendants for the immediate possession of their drilling outfit. On the 6th day of May, 1922, the original com-, plaint in this case was filed. As we have already seen, the suit was commenced in the circuit court for the purpose of obtaining possession of the drilling outfit and damages for the unlawful detention of the same. The drilling outfit was not returned by the defendants to the plaintiffs until the first day of July, 1922.
The plaintiffs introduced evidence tending to show that the rental value of their drilling outfit was not less than $50 per day. The defendants introduced evidence tending to show that its rental value was a very much smaller sum.
The court allowed the plaintiffs $30 per day for the wrongful detention of their drilling outfit, and, after a *416careful consideration of the evidence on this point, we are of the opinion that the finding of the chancellor is not against the weight of the evidence. Therefore it will he allowed to stand.
The plaintiffs also made claim for lost articles and damage to their equipment in the sum of $2,982.07, and the court allowed them $1,725.35. Here again we find the testimony in direct conflict. The chief item on this list was 1,650 feet of drill stem estimated 'by the plaintiffs to he worth $1,497.38.. This was the cost of the lost drill stem'. On the part of the defendants it was shown that there was only 1,300 feet of drill stem lost, and that it had been badly damaged.
The next item was twenty Hickman tool joints at $30 each, of the total value of $600. According to the testimony for the defendants, these tool joints were very badly damaged.
■ The next largest item was $500 estimated to be the damage to the entire outfit above its ordinary wear and tear. The other items on the list were from eleven to seventy-five dollars each for lost tools. We do not think the plaintiffs sustained the loss of the item of $500 for damages to the entire outfit above ordinary wear and tear. While drilling machinery wears out very quickly and is very expensive, as we have already seen, these matters are taken into consideration in fixing the profits to be received by their owner in making drilling contracts. After due consideration of the items on this list, we cannot say that the finding of the chancellor in this respect is contrary to the weight of'the evidence, and his finding on it will be allowed to stand.
The chancellor allowed the plaintiffs' the sum of $1,200 damages for sixteen days’ delay in making the first test. The original contract provided that the defendants should have the right to delay drilling the well by notifying'the plaintiffs to stop drilling, and that for such delay the defendants should pay the plaintiffs the sum of $75 per day. It is claimed by the plaintiffs that this sixteen'days ’ delay before the first test was occasioned by *417the defendants telling them to shut down in order to set an eight-inch casing for the purpose of making the test.
The claim of the plaintiffs for damages in this respect was settled by the supplemental contract of November 12, 1921. As we have already seen, the original contract was modified by it, and its provisions were substituted in part for the provisions of the original contract. It appears both from the terms of the supplemental contract and from the testimony in the case that it was the intention of the parties to adjust all their differences under the first contract by the execution of the two contracts of the date of November 12, 1921. Hence, for the reasons given in the beginning of the opinion where this phase of the case was discussed, we are of the opinion that the chancellor erred in allowing the plaintiffs the $1,200 item for the sixteen days’ delay in making the first test.
The plaintiffs have taken a cross-appeal, and they insist that the chancellor erred in not allowing them $461.10 for the delay in furnishing waiter under the original contract. For the reasons given above, the claim of the plaintiffs for damages in this respect was also settled under the supplemental contract of November 12, 1921.
There are several other smaller items argued in the brief on the cross-appeal, but we do not d°em it necessary to give them a separate discussion. We are of the opinion, after a careful consideration of the testimony, that the finding of facts made by the chancellor was correct, except as to the $1,200 item above stated.
Several other matters are argued at length in the respective briefs of the attorneys on both sides; but the conclusions of law which we have reached and announced above renders it unnecessary to set out or discuss these matters.
If we are correct in hoi dina: that the purnose of executing the supplemental contract of November 12, 1921, was to modify the original contract and to adjust *418all prior differences and claims of damages of the parties under that contract, it follows that the chancellor was right in his statement of the accounts between the parties, except as above indicated.
The result of our views is that the chancellor should have rendered judgment in favor of the plaintiffs against the defendants for the sum of $8,723.35, instead of $9,923.-35. Therefore it will bo ordered that judgment be rendered here in favor of the plaintiffs against the defendants for the sum of $8,723.35 with six per cent, interest thereon from the 31st day of October, 1923, the date of the decree in the chancery court, until paid.
It is ordered that the decree of the chancery court be modified as indicated in the opinion, and as modified that it be affirmed.
