Crosby, J.
These are two actions of contract to recover commissions alleged to have been earned by the plaintiff under a written contract dated August 16, 1920. They were consolidated and referred to an auditor who in the first case (numbered 134,562 on the docket of the Superior Court) allowed certain claims of the plaintiff and disallowed the others; and in the second case (numbered 143,412 on the docket of the Superior Court) found for the defendant. The sums so allowed amounted to $7,781.66; the auditor deducted two payments of $1,000 each, leaving a balance of $5,781.66, which he found the plaintiff was entitled to recover with interest. The cases were afterwards tried together before a jury in the Superior Court; in the first case a verdict was returned for the plaintiff in the sum of $11,525.35; in the second case the court directed a verdict for the defendant. The cases are before us on exceptions taken by the plaintiff and the defendant to requests given and refused by the trial judge in the first case, and to exceptions taken by the plaintiff in the second case.
The defendant is a corporation which manufactures an amusement device known as the “ Dodgem.” The “ Dodgem ” consists of a contrivance in the nature of a small, circular automobile containing a motor; the machine seats two persons and is operated and controlled by the passenger. [421]*421A set of fifteen such cars constitutes what is known as a “ ride.” These rides operate on a smooth surface in an enclosed area, and, it appears, are in use in a number of amusement parks throughout the country. One Pratt was the treasurer, general manager and principal business agent of the corporation. The contract under which the respective rights and obligations of the parties are to be governed was dated August 16, 1920, and was to continue for one year thereafter. Material portions of the contract are as follows:
“ The party of the first part hereby agrees to pay the party of the second part the sum of One Thousand dollars (1000.00) as commission for each fifteen car Dodgem ride, so called, sold by her at the sum of fifteen Thousand dollars (15000.00) : — the following acts by the said party of the second part being sufficient to entitle her to any sums of money which may be due her as herein provided, namely: — the party of the second part shall make an appointment for the consummation of a contract of sale between the prospective purchaser and the party of the first part, or the party of the second part shall notify the party of the first part by mail or telegram of the intention of a prospective purchaser solicited by the party of the second part for the purpose of consummating a contract of sale. The,party of the first part further agrees to pay the party of the second part a sum equal to 10 per cent on all monies received on any contract of sale solicited by her as above mentioned over and above fifteen Thousand dollars.
“ The party of the first part further agrees to pay to the said party of the second part a sum equal to 10 per cent on any cars which may be sold by said party of the first part to any purchaser solicited by her in addition to original ride sold said purchaser at any time within one year from date of the original sale to said purchaser.
“ The party of the first part agrees to pay to the party of the second part any monies due her as hereinbefore provided in the following manner: namely; one half of said sum upon signing of any contract of sale with any purchaser as above provided; and a note for the balance payable 45 days after date of signing of said contract of sale.
[422]*422“ The party of the first part is not to be held responsible for any expenses incurred by the said party of the second part in connection with the sale of the Dodgem ride.”
As all the questions involved arise under this contract they may be considered in one opinion.
FIRST CASE.
The auditor made specific findings on each of the seventeen items contained in the schedule annexed to the plaintiff’s declaration in the first case, allowing some of them and disallowing others. The trial in the Superior Court was upon the auditor’s report and other evidence; some but not all of the evidence was reported.
While this contract was in force, namely, on December 10, 1920, the plaintiff entered into another agreement with a firm known as Miller and Baker, which at that time was also an agent of the defendant in the sale of Dodgems on commission. This contract by its terms was to remain in force until August 15, 1921, substantially the time when the contract between the plaintiff and the defendant would expire. The plaintiff entered the employ of Miller and Baker as agent for the purpose of selling Dodgems manufactured by the defendant; by the terms of this contract she was to receive for her services for each fifteen car ride sold by her the sum of $500, and in case of a sale of a twenty car ride she was to receive $587.50 and in addition thereto five per cent on the purchase price of any ride in excess of twenty cars “ and at the same rate for any sale of exclusive right.” All travelling expenses of the plaintiff incurred by her in endeavoring to effect any sale were to be paid by Miller and Baker. She was also to be paid five per cent on the purchase price on any cars which might be sold to any purchaser, " in addition to original ride sold said purchaser at any time within one year from the date of said original sale to said purchaser.” This contract contained other provisions which it is unnecessary to refer to.
It is the contention of the defendant (1) that its contract with the plaintiff was abrogated or rescinded when she entered into the contract with Miller and Baker, and (2) [423]*423that apart from having entered into the second contract the plaintiff is not entitled to certain commissions claimed by her for the reason that she did not sell the rides in conformity with her agreement with the defendant. -
Under the second contract the plaintiff was to receive only about one half what she was entitled to get from the defendant on the sale of a fifteen car ride, but she was to receive all her expenses from Miller and Baker, and in the event of a sale of twenty cars she was to receive $87.50 from the latter and $87.50 from the defendant which it had agreed orally to pay as an inducement to her to sign the contract with that firm.
For these reasons and upon other evidence the defendant contends that the second contract was inconsistent with that previously entered into with the defendant whereby as matter of law the original contract was rescinded; that by entering into the second contract the plaintiff undertook to “ serve two masters ”; and that such action was detrimental and adverse to her principal, the defendant. We are of opinion that, in view of all the evidence, this contention cannot be sustained. There was evidence that the second contract was entered into by the plaintiff at the request of Pratt, the defendant’s treasurer and general manager, who had full knowledge of the facts. The plaintiff testified that Pratt told her in substance that, as she and Miller and Baker were at times seeing the same prospective customer, confusion resulted; that he was anxious to have her enter into the second contract; that he said to her, “ Another thing, you can’t go wrong. You have always got your contract you can fall back on. Go out and try it. You have nothing to lose. ... You have always got your old contract to fall back on, and I will appreciate it if you will get together with them.”
The auditor found that, when the plaintiff was finally induced by the defendant to enter into the second contract, Pratt told her it would be greatly to her advantage to do so as the Pratt Company would not pay her expenses and Miller and Baker would; that owing to the experience and extensive acquaintance of that firm it was in a much better [424]*424position than the defendant to furnish her with “ live leads,” by which is meant in the trade “ more than merely possible customers ”; that in addition to her commissions in the sale of Dodgems, she -could materially increase her income by the sale of Miller and Baker’s other amusement devices; that such contract might end the conflict of agents; that nothing was said at this conference that by making the second contract her contract with the defendant should become abrogated, or that she surrendered any rights thereunder; that on the contrary Pratt gave her to understand that her proposed contract with Miller and Baker “ would be merely in the nature of an experiment,” and that if she found it unsatisfactory she could have her contract with the defendant to fall back upon. After the second contract was made, the plaintiff testified, “ I wrote to Miller and Baker and told them I was writing to prospects, and told them I was representing both the Stoehrer & Pratt Company and Miller and Baker, and then I also wrote the prospects that way.” She further testified that the firm of Miller and Baker failed to perform its contract with her in that it never gave her any “ live leads ” where she could go and close up quick sales; and that soon after the contract was executed it failed to pay her travelling expenses and was continually indebted to her therefor and still owes her over $1,200 on that account. It is earnestly argued by the defendant that. as the plaintiff was to receive her travelling expenses under the second contract that the contract with the defendant was terminated. Although this was a circumstance to be considered, it could not be ruled as matter of law that the original contract was thereby abrogated. It is manifest that upon this evidence the jury could have found that the defendant, as well as Miller and Baker and prospective customers, knew that the plaintiff was acting under both contracts, and that the defendant recognized her right to do so.
It does not appear from either contract that the plaintiff was restricted as to territory within which she might make sales, or that she acted as an exclusive agent of either the defendant or Miller and Baker. The auditor found that by a contract dated September 14, 1920, the defendant made [425]*425Miller and Baker its agent, and thereafter “ had continuoüsly a half a dozen agents besides Greenburg and Miller and Baker in the field selling Dodgems, each unrestricted as to territory.” It is plain that it could not properly have been ruled that the plaintiff’s contract with the defendant was abrogated by reason of the making of the second contract, or because of the oral agreement under which the defendant promised to pay her $87.50, previously referred to. The principle that one who acts in a representative capacity is not permitted in the performance of his duties to put himself in a position antagonistic to the interests of those whom he represents, in view of the evidence in the present case, is not pertinent. See Quinn v. Burton, 195 Mass. 277, and cases cited. It follows that the defendant was not entitled to a ruling that it had proved an affirmative defence. The defendant’s requests 1 to 22 both inclusive, 43, 44, 45 and additional request 3, so far as they are requests for rulings of law, were rightly denied, and the defendant’s exceptions to the refusal to give them must be overruled.
It is also the contention of the defendant that, if the plaintiff had a right to operate under both contracts, she is not entitled to certain commissions claimed because she did not make such sales in conformity with the agreement. The transactions upon which she contends that she was entitled to a commission and with reference to which the defendant requested certain rulings at the trial before the jury are dealt with separately by the auditor and will now be considered.
In April, 1921, a twenty car Dodgem ride was sold to George J. Cleveland at a cost of $14,000. After the original contract between the plaintiff and defendant had been made, it was modified to the extent that the plaintiff should receive a commission of $1,000 on each fifteen car ride sold by her for $10,500. The auditor found that the plaintiff was not entitled to a commission on this sale. There was evidence that Cleveland sent one House, his associate in business, to New York to look at a Dodgem ride that had been installed there; that House called on the plaintiff; that she showed him the ride and notified the defendant that House had asked her to prepare a contract, which she did; that the [426]*426contract was signed by the plaintiff, representing the defendant, and by House, representing Cleveland; and $500 was paid by House to the plaintiff and forwarded by her to the defendant. This evidence warranted a finding that the plaintiff was the efficient cause of the sale. The defendant’s requests 25, 26, 27, 29, and 2 of the additional requests were rightly denied.
The plaintiff claimed a commission on a ride sold to one Riszk. The plaintiff showed the ride to Riszk who told her he was ready to buy but wanted to know the terms. He told her that one Nabham was friendly with Pratt and that he thought Nabham could get better terms from Pratt. She wrote Pratt informing him of Riszk’s call and that she had shown him a ride; afterwards Pratt gave Nabham a lower price and he bought ten cars and turned them over to Riszk. The auditor found that the plaintiff was entitled to a commission on this sale. The jury were warranted in finding that she was the efficient cause of the sale and that Riszk was the real party in interest. The defendant requested the court to rule “ That the sale of a ride to Charles Nabham and the transfer by him of said ride for the consideration of eight hundred dollars ($800.00) to one George Riszk, does not entitle the plaintiff to a commission for the same to said Riszk.” The defendant now contends that as the plaintiff’s right to recover under the contract was limited to a sale of fifteen rides, and as this sale was for only ten, that she cannot recover. This question, however, does not seem to have been raised at the hearing before the auditor or when the case was tried in the Superior Court. The request for ruling in substance is that because the sale was made to Nabham, who transferred the ride to Riszk, the plaintiff cannot recover. If the defendant desired to raise the question that the sale was not within the terms of the contract he should have done so at the trial.
The plaintiff claimed a commission on the sale of thirty cars to Riverview Park. For some time previous to this sale the defendant and Miller and Baker had been in communication with the manager of the park trying to sell him a Dodgem ride. The auditor found that a contract had been [427]*427prepared, but had not been signed; that at a convention held in Chicago, Miller and Baker, Pratt and the plaintiff attended; that Pratt asked the plaintiff to use what influence she had to get the contract signed as it would help the Pratt company in selling Dodgems; thereupon she saw Hodge, the assistant manager of the park, and urged him to get the contract signed; that he said he would see Schmidt, the general manager, about it; that the plaintiff then saw Schmidt and urged him to give her the contract; that he told her that if she would call at Riverview Park the next morning he would give her a signed contract; that she communicated this to Pratt; that she and Pratt went to the park office on the next day and there in Pratt’s presence she urged Schmidt to sign the contract and give it to her; that he did so, stating he would send a deposit check to Pratt, which he did; that thereupon the plaintiff handed the signed contract to Pratt; that it was for a fifteen car ride at $700 a car, and later it was increased to thirty cars. We are of opinion that upon these findings and the other evidence the jury were warranted in finding that the plaintiff had earned a commission on this sale.
The plaintiff claims a commission on a sale to one Hinkleday. It appeared that previous to this sale a twenty car ride had been sold by the plaintiff to one Aeschbach, who cancelled his contract and forfeited a deposit of $500; and afterwards a contract of sale was made with Hinkleday for a twenty car ride to be used in the same location in place of the Aeschbach contract. The auditor found that the plaintiff was entitled to a commission on the sale to Aeschbach, but was not entitled to a further commission on the sale to Hinkleday. The defendant contends that the evidence was not sufficient to warrant a finding that the plaintiff was entitled to a commission on this sale, but we are of opinion that it was for the jury to determine that question upon all the evidence including the auditor’s report. The defendant also contends that, as Aeschbach cancelled his contract with the defendant, the plaintiff cannot recover a commission for the sale to him, or that in any event her recovery is limited to $1,000, and that she is not entitled to $350 [428]*428additional. The auditor found that $1,350 was due the plaintiff. Under the contract she was entitled to receive a commission of $1,000 on each fifteen car ride sold by her for $10,500. The evidence justified a finding that she had earned a commission of $1,000. But to entitle her to a further commission of ten per cent she must prove that the defendant received on the contract a sum in excess of $10,500; it appears that but $500 was paid on this contract and that it was afterwards cancelled. It follows that the defendant’s request for ruling that the plaintiff could not recover a sum in excess of $1,000 for a commission on the sale to Aeschbach, should have been given.
The plaintiff seeks to recover a commission on a sale of twenty cars to Dominion Park in Montreal, Canada. The auditor found that the commission for this sale, $587.50, had been charged by her to Miller and Baker in a statement which she had rendered to the defendant in settlement with the latter and that the defendant had paid her one half of that commission (charging it to Miller and Baker). The balance of $293.75 the plaintiff also seeks to recover from the defendant. The amount so claimed was a debt due to her from Miller and Baker. The defendant is not liable therefor and the auditor so found. The plaintiff contends that the defendant promised to pay it, but there is no evidence to show that any promise was made by any one representing the defendant sufficient to satisfy the statute of frauds. The record recites “ There was no memorandum or agreement in writing introduced by the plaintiff showing a promise on the part of the defendant to pay to her this indebtedness of Miller and Baker.” The defendant’s requests 38, 39 and 40 should have been given.
The plaintiff seeks to recover a commission for securing locations at Luna Park, Coney Island, and at Canarsie Shore, the amount so claimed being $500 for each location, and in addition she seeks to recover commissions of $1,350 for a ride sold at each of these places. The auditor found that she was entitled to recover $500 for securing the location at Luna Park, but was not entitled to recover on the claim for selling a ride there or for securing the location or installing [429]*429the ride at Canarsie Shore. At the trial in the Superior Court the defendant requested the court to rule in substance that the plaintiff could not recover for rides installed at either of these places; and that if the defendant was hable for securing a location at Luna Park the plaintiff could not recover more than $500. These requests were refused and the defendant excepted. As all the evidence is not reported, we are unable to say as matter of law that the refusals of the court to give the defendant’s requests numbered 32, 33 and 35 were error. If, as the jury may have found, the plaintiff introduced evidence which controlled the finding of the auditor upon these items, she was entitled to recover a commission not only for securing a location at Luna Park but also for similar services at Canarsie Shore and for rides sold at each of these places.
The auditor found that the plaintiff was entitled to a commission of $1,000 on a sale of a fifteen car ride to one Neble. At the trial the defendant, by requests 22, 43, 44 and 45, requested instructions to the effect that the plaintiff could not recover a commission for this sale, on the ground that it would be a fraud upon Miller and Baker and for the reason that she, having previously allotted sales to that firm, was estopped from claiming a commission under her contract with the defendant. It could have been found that she was entitled to operate under both contracts and that by so doing she violated no legal obligation to Miller and Baker. The defendant’s requests relating to this sale are overruled.
The plaintiff’s exceptions in the first case arise by reason of an alleged sale of one hundred and thirty-five cars to one Tonner. The plaintiff contends that she was instrumental in making such a sale under the contract with the defendant hereinbefore referred to, and is thereby entitled to recover $9,400. The auditor found that the plaintiff was entitled to recover $1,000. The trial judge instructed the jury upon this item as follows: “ If the jury shall find that the defendant is liable to the plaintiff for the sale of a ride to one Tonner, then they must find that the defendant is only hable to her for a sale of twenty cars.” To this instruction the plaintiff excepted.
[430]*430Upon this item the auditor found the following facts: The plaintiff first met Tonner early in February, 1921, in the defendant’s New York office, where he had been brought by one Neble to see a sample car on exhibition there. Later in the same month there was a convention of amusement park men held in Chicago. Pratt attended the convention and the plaintiff, at his invitation, accompanied him to help sell Dodgems, the Pratt company paying her travelling expenses, but not her hotel bills. They met Tonner in Chicago in company with Neble. Pratt urged the plaintiff to go to Riverview Park in Neble’s absence, and she and Pratt took Tonner to Riverview Park and showed him the ride. On their return to the hotel, Pratt and the plaintiff took Tonner to her room and discussed a sale of Dodgems to him; for the exclusive right to sell cars in England, he agreed to buy .seventy-five cars, and Pratt drew a contract for the sale of that number of cars at $700 each. The contract was signed by Pratt in behalf of the defendant, and by Tonner, in the presence of the plaintiff; and Tonner gave Pratt a check payable to the defendant for $2,000 as a deposit on account of the purchase. Later, in response to a request for funds by the plaintiff, Pratt indorsed the check over to her; she deposited it for collection, but it- proved worthless and was returned to her unpaid, and she notified Pratt to that effect. On returning to Lawrence, Pratt wrote the plaintiff a letter dated February 22, 1921, in which he referred to this and another sale of cars and stated: “ I called on you for help in both cases, so of course acknowledge my indebtedness and am pleased to pay you.” On February 24, 1921, Tonner went to Lawrence and discussed further with Pratt the purchase of cars. In a letter of that date Pratt gave the plaintiff the details of this conference, stating: “ He (i.e. Tonner) has signed for one ride (i.e. 20 cars) and also 55 cars more to be shipped later. I received a cash deposit of $750, all the money he had with him, and am shipping a car to him to-morrow, on receipt of which he is to remit $6,250. When I receive this amount from him in 15 days I will credit you with commission on same.”
The auditor further finds that on February 25, 1921,. a [431]*431new contract was executed by Tonner and by Pratt, on ber half of the defendant, for the sale to Tonner and the purchase by him of a twenty car ride for $14,000, of which $750 was to be paid on execution of the contract, $6,250 within fifteen days thereafter, and $7,000 on receipt of bill of lading; that in this contract Tonner agreed to buy not less than fifty-five cars in addition at $700 each and to pay $5,000 on each order in advance; that the balance due on each shipment was to be paid on receipt of the bill of lading; that Tonner further agreed in this contract to purchase during the season of 1922 at the above prices and terms, not less than sixty additional cars, delivery to be made not later than December 31, 1922. This contract covered altogether one hundred and thirty-five cars at $700 each, a total of $94,500. On February 28, 1921, Pratt informed the plaintiff by letter that Tonner had bought seventy-five cars for England. On March 17, 1921, Pratt wrote the plaintiff that Tonner “ had made good ” and that the Pratt company was preparing to make shipment to him. The auditor further found that under the above contract the defendant delivered to Tonner only twenty cars, and received from him on account thereof only $7,000; that in her statement to Pratt, prepared on her return from the Chicago convention, the plaintiff gave Miller and Baker credit for the sale of the twenty cars to Tonner; and under her contract with them, claimed a commission of $587.50 together with $87.50 from the defendant. The auditor further found that in view of Pratt’s letters to the plaintiff of February 22 and 24, 1921, above referred to, the defendant owes her $1,000 as commission on these twenty cars.
The contract between the parties is definite in its provisions and is free from ambiguity. By its terms the defendant agrees to pay the plaintiff $1,000 as commission for each fifteen car ride sold by her for $15,000 (the last amount being afterwards changed to $10,500), provided she should make an appointment for the prospective purchaser with the Pratt company for the consummation of a contract of sale between them; or the plaintiff should notify the defendant by mail or telegram of the intention.of a prospective pur[432]*432chaser selected by her to consummate such sale. The contract further provides that the defendant should pay the plaintiff a sum equal to ten per cent on all moneys received on any contract of sale solicited by her over and above $15,000; that the defendant shall pay the plaintiff a sum equal to ten per cent on any cars which the defendant sold to any purchaser solicited by her in addition to the original ride sold to such purchaser, at any time within one year from the date of the original sale to such purchaser; that the defendant shall pay the plaintiff any moneys due her, one half thereof upon the signing of any contract of sale with any purchaser; and that the defendant shall give her a note for the balance payable forty-five days after such signing.
We construe this contract to mean that, if a written contract for the purchase of a ride, binding upon the seller and purchaser, was made, the plaintiff became entitled to a commission, provided she made an appointment for the consummation of the contract between the prospective purchaser and the defendant or notified the defendant by mail or telegram of the intention of a prospective purchaser solicited by her for the purpose of consummating a contract of sale; but that she was not entitled under any provision of the contract in the event of a sale of a greater number than fifteen cars, to an additional commission unless and until the defendant had been paid by the purchaser for such cars so sold in excess of fifteen. It follows that as Tonner paid the defendant only $7,000 a sum less than the price of fifteen cars, that the plaintiff cannot recover a sum greater than $1,000. The exception of the plaintiff to the instruction that “ If the jury shall find that the defendant is liable to the plaintiff for the sale of a ride to one Tonner, then they must find that the defendant is only liable to her for a sale of twenty cars,” must be overruled. The plaintiff’s second request “ That if the true import and meaning of an instrument in writing cannot be determined from its language, it must be construed most strongly against the party using the uncertain language,” must be overruled. As the contract is free from ambiguity, the request is not applicable.
[433]*433SECOND CASE.
This was an action upon the contract referred to in the first case to recover commissions upon- certain sales alleged to have been made by the plaintiff and set forth in Exhibit B of her declaration. The auditor found that she was not entitled to recover for any of these sales, on the ground that, upon the facts found by him, the sales were not made through her efforts or were not made by her within one year after the date of original sales made by her, in accordance with the terms of the contract. The trial in the Superior Court was upon the auditor’s report, upon her oral testimony, and upon certain correspondence offered by her. At the conclusion of the evidence, the presiding judge instructed the jury to return a verdict for the defendant on the ground that there was no evidence to control the auditor’s finding. To the verdict so ordered the plaintiff excepted.
After a careful examination of the findings of the auditor and the other evidence introduced at the trial, we are of opinion that the oral evidence and correspondence offered at the trial did not in any way control or affect the auditor’s findings. The auditor’s report, finding for the defendant, is prima facie evidence and requires a verdict for the defendant unless there is other evidence either in the report or outside of it to control the findings. Anderson v. Metropolitan Stock Exchange, 191 Mass. 117, 121. Wakefield v. American Surety Co. of New York, 209 Mass. 173, 176, and cases cited. As only one conclusion could properly be drawn as matter of law a verdict was rightly directed for the defendant.
It follows that, in the first case, the right of the plaintiff to recover a commission on the sale of a ride to Aeschbach is limited to $1,000, and she is not entitled as matter of law for the reasons previously stated to recover $350 in addition thereto; nor is she entitled to recover from this defendant $293.75 as commission on the sale of a ride to Dominion Park. These amounts may have been included in the verdict. If the plaintiff within thirty days from the date of the rescript files a remittitur of $643.75 and interest thereon from the date of the writ to October 19, 1923, the date of [434]*434the verdict, the defendant’s exceptions are to be overruled; otherwise they are to be sustained. In each case the plaintiff’s exceptions are overruled.
So ordered.
