McClain, J.—
The first trial of this case in the lower court resulted in a judgment for defendant on a directed verdict, which was reversed on appeal. See 119 Iowa, 410. On the second trial there was a verdict for the plaintiff and judgment thereon, from which the present appeal was taken, and the judgment was affirmed; but, a rehearing having been granted, the case is now before us for final determination. The essential facts to be considered in passing upon the alleged errors relied on in the present submission are as follows: The defendant on May 30, 1899, signed and delivered to plaintiff a written instrument appointing plaintiff his agent and authorizing him to sell two tracts of land, one in Calhoun county and the other in Greene county, otherwise specifically described, for an agreed commission of $1 per acre, which agreement was to be in force for one year. In this instrument the defendant authorized the plaintiff to [295]*295enter into a written contract for bim and on his behalf for the sale of said property, and also agreed to pay plaintiff “ the above-named commission as soon as the deal is made for making such transfer or deal, sighting (sic) me to a prospective buyer or being instrumental in any manner whatever.” The terms of sale named in the instrument were “ $35 per acre, $2,000 cash; balance will give time on at 6 per cent, interest.” On May 21, 1900, the plaintiff produced to the defendant as a prospective buyer one Cathcart, who as the evidence tended to show said to the defendant that he had come in answer to an advertisement of plaintiff, which he had seen, and stated that he believed that he would buy the Greene county land at $35 per acre. Defendant replied that he would not sell it at that price, and that $40 per acre was the lowest price that would buy it. Cathcart inquired whether he had not listed it at $35 per acre, and defendant said: “ Yes; but it is worth more money, and I won’t let it go at that price.” Thereupon the plaintiff told defendant that if he did not sell according to the contract plaintiff expected him to pay his commission, and defendant said, “ I will pay you your commissionthat he would rather pay such commission, because he would rather lose $1 an acre than lose $5 on the price. Defendant also said that, even if he wanted to sell, his wife would not sign the deed, but that he would go into the house and see her, and he then reported that she was not satisfied to sell, and Cathcart, with plaintiff, terminated the interview.
There was testimony of Cathcart to the effect that at the time this conversation was held with defendant he was ready, willing, and able to buy the land on the terms set forth in the written instrument and in the advertisement, including the payment of $2,000 cash; that he did not have that amount of money with him but that he could have procured it within one or two days. There was further evidence tending to show that later in the same day at plaintiff’s office Cathcart had another conversation with defendant with ref[296]*296erence to the purchase of the farm on somewhat different terms from those embodied in the written instrument and advertisement; but no arrangement was perfected, and Oath-cart made no further effort at that time to effect the purchase. Subsequently there were further negotiations between Oath-cart and defendant with reference to the purchase of the Greene county land, and also with reference to the Calhoun county land; but these negotiations did not result in a sale. In the meantime, however, plaintiff had claimed his commission from defendant on the ground of the production of Oathcart as a purchaser ready, willing, and able to pay; and this action is brought on the theory that plaintiff’s commission, as provided for in the written instrument, became due on the refusal of defendant to accept the purchaser thus offered — 'plaintiff’s allegation being that pursuant to and in conformity with the provisions of said written contract, set out as an exhibit to plaintiff’s petition, plaintiff did on May 21, 1900, procure a purchaser ready and willing to purchase upon the terms agreed upon in the writtén contract, who offered to pay the price named therein, but that the defendant then and there refused to sell said land at the price stated and demanded a greater price. Plaintiff also alleged by way of amendment that he cited defendant to a buyer, and was instrumental in bringing defendant and said buyer together, and that he had performed the conditions of the contract on his part.
In a second amendment the plaintiff alleged that defendant made and delivered to him his certain contract and agreement (referring to the same instrument set out as an exhibit to the original petition), which the plaintiff orally accepted, and that plaintiff entered upon the performance of said contract with the full knowledge of the defendant; that plaintiff found a purchaser at and upon the terms and conditions therein stated, whom he produced to the defendant; that the defendant refused to comply with the terms of the contract and the agreement, and refused to make and execute [297]*297a conveyance of said real estate upon tbe terms and conditions stated in said contract, demanding a greater price than that specified; and, further, that Catheart as such prospective purchaser was then and there ready and willing to purchase at and upon the terms and conditions specified and agreed upon in said contract and agreement, and hy the refusal of defendant to comply with the terms of the agreement plaintiff was prevented from a further compliance and defendant thereupon. waived a further compliance; that plaintiff then and there demanded of and from defendant the payment of plaintiff’s commission as provided in said contract, and that no part of said sum has ever been paid; and that, but for the refusal of the defendant to comply with the contract and agreement, said Catheart would have purchased said real estate at and upon the conditions and terms specified. Defendant denied generally the allegations of plaintiff’s petition and the amendments thereto, and for further answer alleged a material alteration of the instrument, thus raising an issue which was submitted to the jury and found against the defendant. With reference to this issue of alteration no question is now raised, and the only issue of fact with which we are concerned is that relating to the performance by plaintiff of the conditions of the contract and agreement to be by him performed entitling him to his commission.
a. Contracts: in-prejudice.' I. One of the contentions for appellant is that plaintiff sought recovery on a written contract, and the court instructed the jury that there could be no recovery by plaintiff unless the jury found that the plaintiff and defendant entered into the written contract pleaded by defendant and introduced by him in evidence, and that as the contract thus pleaded and proven was signed only by the defendant, and was orally accepted by the plaintiff, the contract was oral, and not in writing, and the plaintiff could not, therefore, recover; there being a variance between the allegations and the evidence. It is to be noticed, however, that plaintiff in his amendment expressly alleged [298]*298the execution and delivery by defendant of the written instrument, and its oral acceptance, and the performance thereof by plaintiff.
It further appears that in the instructions asked by defendant and given by the court the instrument is expressly referred to as the writing sued upon, and that the question of variance between the allegations in the pleadings and the evidence as offered in support thereof was in no way raised until after verdict. As the plaintiff expressly relied upon a writing executed by defendant and orally accepted by plaintiff and acted upon by him, and the evidence tended to support the allegations in this respect, there was no prejudicial error in referring to the instrument as a written contract. It is not claimed that the written instrument signed and delivered by defendant and acted upon by plaintiff was not a mutually binding obligation or contract. The claim is that it was not a written contract. As there is no controversy with reference to the obligations of the parties arising by the delivery of the instrument and its acceptance, we fail'to see any possible prejudice which could have resulted to defendant from the reference in the instructions to the instrument as the written contract of the parties.
g. Written contracts. Further, we think that a written instrument purporting to set forth the mutual obligations of a contract, which, though unilateral in form and signed by one party only, is, by delivered to the other and accepted ag contra,ct between the parties, is a written contract. Where a written agreement signed by one party is accepted and adopted by the other, and acted upon, it becomes their contract in the same sense as though both parties had signed it. Attix v. Pelan, 5 Iowa, 336; Dows v. Morse, 62 Iowa, 231; Sellers v. Greer, 172 Ill. 549 (50 N. E. 246, 40 L. R. A. 589); Vogel v. Pekoc, 157 Ill. 339 (42 N. E. 386, 30 L. R. A. 491) ; Horn v. Hansen, 56 Minn. 43 (57 N. W. 315, 22 L. R. A. 617) ; Bigler v. Baker, 40 Neb. 325 (58 N. W. 1026, 24 L. R. A. 255) ; Graves v. Smedes’ [299]*299Adm’r, 7 Dana (Ky.) 344; Woodlock v. Meyerstein, 5 Mo. App. 591. Tbe cases relied on for appellant relate to tbe question of mutuality, and bold that a written proposition, not accepted, does not become a written contract. It would certainly be a startling proposition to announce that an action by tbe grantee on tbe covenants of a deed signed by tbe grantor and accepted by tbe grantee is an action on an oral contract, barred under our statute of limitations in five years, ratber than an action on a written contract, barred only in ten years from tbe beach thereof (see Mitchell v. Kepler, 75 Iowa, 207; Yancey v. Tatlock, 93 Iowa, 386) ; or that oral evidence of contemporaneous conversations is admissible to vary tbe terms of a written instrument purporting to contain tbe mutual agreement of tbe parties, signed by one and accepted by tbe other as containing such agreement. There is no reasonable ground nor authority for saying that such an instrument is not a contract in writing.
T ma™notrbe assigned. II. On tbe examination of defendant as a witness he was asked whether be bad written an anonymous letter to the plaintiff with reference to tbe trouble between them, advising him in substance that he was likely to get hurt if the case should go against the defendant or ^ defendant should be put to any expense by reason of such controversy. Defendant denied any responsibility for or knowledge of tbe writing of tbe letter. There was testimony tending to show the letter to be in defendant’s bandwriting, and it was admitted in evidence over objection of defendant. The court gave an instruction, requested by defendant, with reference to this evidence, to tbe effect that tbe jury might consider the writing of the letter, if it were shown to have been written by the defendant, as establishing the fact that defendant had sworn falsely or mistakenly,. but should give effect to such evidence only as bearing on the credibility of defendant as a witness, and not as establishing that the proposed purchaser was ready, willing, and able to buy on the terms of the writing signed by the [300]*300defendant. ' This instruction counsel for defendant characterizes as erroneous and confusing, and perhaps the instruction is open to this objection; but, as it was given on defendant’s request, he cannot complain.
4‘ evidence” oi? OTorCTof Nor can defendant complain of the admission of the letter in evidence over his objection, in view of this instruction directing the jury to consider it for only a specific pur-Pose> f°r which by the requested instruction he admits that it might properly be considered. Had the defendant asked an instruction that the admitted evidence should not be considered for any purpose, his objection to the admission of the evidence would have been fully preserved. Had no instruction whatever been asked upon the subject, the court might notwithstanding have cured the error, if any there was, by directing the jury not to consider the letter in reaching a verdict. But, after defendant had specifically asked that the consideration of the evidence be limited to its bearing upon the credibility of defendant’s testimony, the court was not called upon to assume that the defendant still relied upon the admission of the evidence as constituting error, and might properly give the instruction asked, without further attention to the question whether the admission of the evidence for that purpose was erroneous.
b. Evidence: ad-former trial. In rebuttal plaintiff offered in 'evidence a portion of the transcript of the evidence on the former trial, showing that, when the attorney for plaintiff on that trial sought to show that defendant did not offer to sell to Cathcart at the price named in the contract, the attorney for defendant admitted that there was no such offer. Counsel for defendant claim that there was error in admitting this evidence over defendant’s objection, contending that the admission of counsel for a party on one trial of a case does not constitute an admission on another trial.. This, no doubt, is true; but that admissions made for a party, in pleadings or otherwise, appearing in the record of one trial, may be shown on another trial, subject, of course, to the [301]*301explanation that snch admissions were made by mistake or without authority, seems to be well settled. Peden v. Chicago R. I. & P. R. Co., 78 Iowa, 131; Shipley v. Reasoner, 87 Iowa, 555; Ludwig v. Blackshere, 102 Iowa, 366. Whether or not the exception to the admission of this testimony was well taken is immaterial, however; for the court instructed the. jury at defendant’s request that such an ad-, mission was not conclusive, and did not deprive the defendant of the right to show by testimony that the fact was otherwise than in accordance with this admission. What was said as to the alleged error in the admission of the anonymous letter is also applicable here. It is not open to the defendant, after having requested the court to instruct the jury as to the effect to be given to this evidence, to now contend that it was inadmissible for any purpose.
e. Agekcy: commission for the sale of land: right of recovery. III. The contract between defendant and plaintiff provided that plaintiff might make a written contract for defendant for the. sale of the property on the terms specified. It further provided that defendant would pay . -t • . • j.i i • • u plaintiff the agreed commission as soon as- . 0 the deal is made for making such transfer or deal sighting me to a buyer or being instrumental in any manner whatever.” Plaintiff did not attempt to earn his commission by entering into a written contract for defendant for the sale of the property, perhaps for the reason that the proposed purchaser was not willing to accept such a contract ; but he did attempt to earn his commission by citing the defendant to a buyer — that is, by producing a purchaser ready, willing, and able to make the purchase on the terms specified. It is contended for appellant that no commission ever became due the plaintiff because no deal was ever made, and' that, if defendant by his wrongful, act prevented a deal being made by refusing to make the sale to the proposed buyer on the terms specified in the writing, then -plaintiff’s remedy is for the wrong of the defendant in making it impossible for plaintiff to bring about the condition on which [302]*302payment was to be made. Of course, if the agreement bad been that a commission should be paid only when a sale was effected, the plaintiff would not be entitled to the commission specified in the contract, in the absence of any sale being effected, though he might be entitled to damage for the wrongful act of the defendant in preventing the sale. Milligan v. Owen, 123 Iowa, 285; Ormsby v. Graham, 123 Iowa, 202; Metzen v. Wyatt, 41 Ill. App. 487; Flower v. Davidson, 44 Minn. 46 (46 N. W. 308). But here the right of the plaintiff to a commission was not dependent solely upon perfecting a sale. True, he was to be entitled to his commission if a sale were made by him, exercising his authority to bind the defendant by a written contract of sale; but he was also to be entitled to the same commission if he cited the defendant to a buyer, and for these services his commission was not dependent upon the deal being made* This construction of the contract was accepted by the defendant throughout the trial of the case in the lower court.
Defendant interposed a plea in abatement after the conclusion of the evidence; but this amendment was stricken from the files on plaintiff’s motion, and while the defendant preserved his exception to this ruling, he does not rely upon it in his brief or argument as constituting error.
7. Appeal.-new trial: review. On the trial he asked instructions, which were given, to the effect that plaiñtiff might recover if plaintiff produced a purchaser able to pay the money called for by the terms of sale contained in the writing sued on, and neither by motion for new trial nor by motion in arrest of judgment did he contend that the commission, if earned, was not payable until a sale was made. The motion for a new trial does refer to error in overruling that part of defendant’s motion to direct á verdict which asserted that plaintiff’s demand was not due and that suit was prematurely brought thereon; but, as the motion to direct a verdict is not in the record, we cannot say whether the objection was there sufficiently raised.
[303]*3038. AGENCY: com mission con tracts: con struction. Aside from all this, we think the contract should be construed, as already indicated, as referring to either a transfer or deal on the one hand or producing a purchaser on the other, and that the transfer relates to a completed contract, either by the agent under his authority or by the defendant, while the deal relates to the production of a purchaser ready, willing, and able to purchase on the terms specified. At least three different methods of earning a commission under an agency contract for the sale of real estate may be provided: First, by effecting a binding contract of sale under authority given to the agent to make such contract for the principal; second, by producing a purchaser to whom a sale is in fact made; third, by producing a purchaser ready, willing, and able to buy on terms specified in the agency agreement. Blodgett v. Sioux City & St. P. R. Co., 63 Iowa, 606; Rounds v. Alee, 116 Iowa, 345; Cassady v. Seeley, 69 Iowa, 509; Bird v. Phillips, 115 Iowa, 703. We think the contract, reasonably construed, provided for a commission either on the making of a sale by plaintiff on the terms specified or on the production of a purchaser ready, willing, and able to buy on such terms.
9. Same. All the instructions asked by defendant, many of which were given as asked, assumed that plaintiff had performed his contract and was entitled to his commission if Oathcart was ready, willing, and able l~o make a contract such as described. Defendant cannot shift his ground in this court, and have a reversal on the ground that the actual closing of a contract between Oathcart and defendant was a condition precedent to plaintiff's right to, recover.
10. Same. And, finally, it is elementary that, where one party to a contract attempts to perform and the other refuses' performance, the former may recover as efiectually as though performance had been completed; the refusal to accept performance being a' waiver of [304]*304any further effort on the part of the party offering the performance to carry out the terms of the contract. Such waiver was expressly pleaded by the plaintiff, and the evidence tended to establish it. In the absence of any error in the trial relating to the issue with reference to a waiver, the plaintiff is entitled to the verdict which was secured. We are not cited to any authorities which hold that, where one party attempts to perform and the other is in such a situation that performance might have been accepted by him and the contract completed, the plaintiff is debarred from recovery under the contract and must rely on an action for damage for refusing to allow him to carry out his contract and become entitled to the consideration agreed upon. Where one party to a contract in fact does everything which he is called upon to do to entitle him to the compensation provided for, the other party cannot, by refusal on his part to go on, defeat recovery under such a contract. Larned v. Dubuque, 86 Iowa, 166, 181; Duclos v. Cunningham, 102 N. Y. 678 (6 N. E. 790) ; Stanton v. Barnes, 72 Kan. 541 (84 Pac. 116). The plaintiff did everything which by the contract he was bound to do to entitle him to his commission if he produced a purchaser ready, willing, and able to buy on the terms of the contract, and defendant could not, by his own act in refusing to proceed, defeat recovery of the agreed compensation. The authorities cited on this point for appellant do not sustain his contention. The question is not here as to whether Cathcart became entitled to a deed, but whether plaintiff produced him as a purchaser ready, willing, and able to buy on the terms of the contract. It is true he would not have, been entitled to a deed until he had paid $2,000 cash and executed a mortgage for the deferred payments; but these subsequent steps in the transaction essential to Oath-cart’s right to sue for specific performance or for damages did not concern this plaintiff. If Cathcart was ready, willing, and able to take, the necessary steps, then plaintiff, by .producing him to defendant, became entitled to his com[305]*305mission. If, when plaintiff produced Catbcart as a purchaser, defendant had put it out of his power to perform them, perhaps plaintiff would not have been entitled to his commission, but only to damages. Iselin v. Griffith, 62 Iowa, 668. The refusal of defendant to proceed was not based on the ground that he was unable to carry out the contract, but on his mere unwillingness to do so. He recognized his obligation and ability to make the conveyance, but insisted that he would prefer to pay plaintiff’s commission rather than carry-out his contract. Defendant cannot now resist payment of plaintiff’s commission on the ground that, although Cathcart was ready, willing, and able, defendant refused to take the subsequent steps required of him to entitle plaintiff to receive such commission. Collins v. Paden, 120 Iowa, 381.
ery of com-ciency of evidence. IV. The case as submitted'to the jury involved the determination of two issues: First, had the written instrument on which plaintiff sued been materially altered ? Second, was Cathcart, when presented by plaintiff to defendant as a prospective buyer, ready, willing, and able to buy on the terms fixed in , ° the writing ? An instruction asked by defendant specifically limited the jury to the consideration of these two questions, and such instruction was given as asked. It is not contended that any instruction inconsistent with this was given. As no complaint is made with reference to the submission of the issue as to material alteration, the finding of the jury bn that issue is conclusive. Sufficiency of the evidence to support the verdict depends upon whether the evidence as to the willingness, readiness, and ability of Cath-cart was such as to justify a finding on that issue in plaintiff’s favor. On the former appeal (119 Iowa, 470), we held that it was competent for plaintiff to show what Cath-cart said to defendant at the first interview, with reference to his readiness and willingness to buy upon the terms mentioned in the instrument. On this trial the same offered [306]*306evidence was received, with other evidence of Cathcart that he was then ready and willing to buy, and that he was able to do so, and conld within a day or two have raised the .money to make the necessary cash payment, if defendant had not refused to sell. This evidence was not contradicted. Oath-cart did not testify that his ability to raise the necessary $2,000 was dependent upon the sale of his farm; but he testified generally as to his ability to raise that amount of money, if necessary, in order to effect the purchase. It is also to be noticed that subsequent conversations relating to the payment of only $1,000 in cash were not predicated upon any expression of doubt by Cathcart as to his ability to raise $2,000, but upon some proposed modification of the terms of the sale by which defendant was to be allowed to retain possession until the 1st of March following.
There was enough evidence to sustain the verdict as to Catheart’s ability to raise the money necessary to complete the purchase, unless, as counsel for appellant contend, no evidence of that fact was sufficient which did not show an actual tender of the cash, or at least the actual possession by Cathcart of that amount of cash in readiness to make a tender if required. It is to be noticed, however, that the issue was not as to performance by Cathcart of a contract to purchase by a specified time. The issue between plaintiff and defendant was simply whether Cathcart was ready, willing, and able. The cases relating to sufficiency of tender of performance of a contract to convey are not in point.
It is further to be noticed that there yet remained ten days within which plaintiff might furnish a purchaser under his contract and thus entitle himself to a commission; and the inability of Cathcart to make payment on the day on which he was presented to the defendant was not material, even though it can be said under the evidence he would not have been able to make the requisite cash payment on that day, if defendant had accepted him as a purchaser. By refusing to proceed to effect the sale to Cathcart, the defend[307]*307ant waved the right to have him proceed further in demonstrating his ability to produce $2,000 in cash within such time' as would have entitled the plaintiff to his commission. Had the refusal to proceed been based upon the inability of Cathcart to procure the money within the necessary time, the objection could no doubt have been obviated. Duclos v. Cunningham, 102 N. Y. 678 (6 N. E. 790).
It is to be borne in mind that under the contract between plaintiff and defendant the proposed purchaser was not bound to pay $2,000 cash until the defendant had furnished an abstract showing a perfect title and made a warranty deed in which his wife had joined. Had Cathcart been in the immediate physical possession of the money, he would not have been required to tender it until defendant had proceeded to the point of furnishing an abstract and being ready to deliver the necessary deed. Defendant, by his own act in refusing to make the sale in accordance with the terms of the agency agreement, prevented the negotiations from proceeding to that point. At the time of this repudiation all that was required of the proposed purchaser was that he be ready, Avilling, and able to go on with the purchase. When defendant had thus repudiated, it was not required of Cathcart that he go through the useless formality of procuring and tendering $2,000 in cash, which defendant had declared he would not accept. With reference to a contract of purchase we have said in Kuhlman v. Wieben, 129 Iowa, 188: “ The statement that one will not comply with the terms of his contract excuses the other party from going through the useless formality of making a tender . . . True, he [the owner] did not say in so many words that he would not convey the land; but that such was the meaning of what he did say and do might have been inferred by the jury.” That renunciation of the contract relieves the other party from any further obligation, and entitles him to sue at once for its breach, is well settled. Roehm v. Horst, 178 U. S. 1 (20 Sup. Ct. 780, 44 L. Ed. 953) ; McCormick v. Basal, 46 [308]*308Iowa, 235. In short, tbe complete answer to appellant’s contention is tbe finding by tbe jury under proper instructions that plaintiff produced a purchaser ready, willing, and able to buy, and who would have bought under the terms of the contract, if defendant had not refused to sell, and that by such refusal appellant waived further performance on the part of the proposed purchaser and rendered it unnecessary for him to proceed further in demonstrating his ability to purchase and in carrying out the contract, which he would have made with appellant, had appellant been willing to proceed with the negotiations.
The cases relied upon for appellant in this connection do not support his contentions. In Mullenhoff v. Gensler (Super. Buff.) 15 N. Y. Supp. 673, especially urged upon our attention, it appeared that the agent was to produce a purchaser by the next morning ready, willing, and able to buy the property for $10,000 cash; that the proposed purchaser did not have that amount of cash, and expressly testified, as the court interpreted his language, that he needed thirty days in which to raise it; and the court held that he was not such a purchaser as required to entitle the agent to his commission. In that case the court expressly recognized the right of the purchaser offered to a reasonable time, at least until the conveyance should be prepared and the negotiations concluded, within which to procure the money, and evidently would have held that the agent was entitled to his commission if the evidence had shown the proposed purchaser to have been able to raise the money within such reasonable time. In Dent v. Powell, 93 Iowa, 711, the seller, instead of repudiating the proposed sale, did everything in his power to carry it out and gave the proposed purchaser every reasonable opportunity to procure the money necessary to do so; and it affirmatively appeared that the proposed purchaser could not raise the money, though he had property from which the claim against him, had the proposed sale been on credit instead of for cash, might have been made. The court simply [309]*309decided that the seller was not bound to waive a cash sale and contract for a sale on credit, under which it would probably have been necessary for him to resort to a suit in order to secure payment. In Watson v. Brooks, 11 Or. 271 (3 Pac. 679), it was held that the production by the agent, on the last day given him for performing his contract, of a purchaser able to pay the stipulated price, but willing to complete the purchase only on condition of being allowed further time to examine the title, did not entitle him to his commission ; time being of the essence of the contract. As we have already said, the evidence established to the satisfaction of the jury, to whom the question was submitted, that the purchaser in this case would have been able to produce the money and carry out the contract of purchase within the time of the agency, if he had not been prevented from doing so by defendant’s renunciation. In Castner v. Richardson, 18 Colo. 496 (33 Pac. 163), the contract of agency was not established, and the court held that the conceded rule that, where the owner engages the services of an agent to sell or negotiate a sale, the agent’s compensation being made dependent upon the consummation of a sale and time not being of the essence of the contract, the agent is entitled to a reasonable time in which to consummate such sale after a purchaser has been found ready, willing, and able to buy upon the terms stated by the owner has no application, especially where the owner had expressly limited the time within which a person not his agent was to procure.and pay over the purchase money. In Hurd v. Neilson, 100 Iowa, 555, the evidence failed to show that the agent had made or negotiated a sale in accordance with the authority given to him, and it was held that the-agent had not shown himself to be entitled to the commission agreed upon; for heihad failed to show either a completed sale or negotiations for a sale in compliance with the authority conferred upon him.
[310]*31012. same. [309]*309Among the many eases to which our attention is called • by counsel for appellant we have failed to find a single one [310]*310which supports his contention that, to demonstrate the ability of the purchaser to carry out the contract contemplated in the agency agreement, it must be shown that the proposed purchaser, when offered, has on his person or instantly within reach the amount of cash required to make the purchase, where something further remains to be done on the part of the seller before he is entitled to receive the cash payment and the latter repudiates the proposed sale and refuses to proceed on the ground that he is unwilling to sell on the terms of the agency agreement. Having elected to repudiate, the appellant was not entitled afterwards to mend his hold by insisting that, if he had not repudiated the contract, the purchaser would not instantly have been able to produce the required cash payment. That a party who has elected one ground of objection cannot afterwards mend his hold and select another, which might have been obviated,' had it then been insisted upon, is well settled. Donley v. Porter, 119 Iowa, 542; Stanton v. Barnes, 12 Kan. 541 (84 Pac. 116). “ Where a party gives a reason for his conduct, and decision touching anything involved in a controversy, he cannot, after litigation has begun, change his ground and put his conduct upon another and different consideration.” Railway Co. v. McCarthy, 96 U. S. 258 (24 L. Ed. 693).
V. There appears to be some contention on behalf of .appellant that plaintiff waived his right to insist on his commission earned by producing Cathcart as a purchaser on May 21st, by subsequently attempting at defendant’s request to induce Cathcart to purchase one or the other of the tracts of land described in the contract of agency. We find nothing in the pleadings suggesting any such issue, and the evidence does not support any such claim. Before there were any subsequent negotiations plaintiff had insisted that his commission was earned and payable, and there is nothing to indicate a waiver of his right to such commission. If plaintiff had subsequently at defendant’s request induced Cath-[311]*311cart to buy, be might have been entitled to an additional commission, not under the original contract, for the subsequent negotiations did not contemplate a sale within the time specified in the original contract of agency, but under an implied contract to make compensation for services thus rendered. Triplett v. Jackson, 130 Iowa, 408. We have no occasion to decide this question, however, for the subsequent negotiations came to naught.
We have considered every phase of this case, and, finding no error to have been committed on the trial and that the verdict is supported by the evidence, the judgment is Affirmed.
