Appeal from an order overruling defendant’s motion for a new trial. Plaintiff, Kirk, brought the 'action to recover upon a contract for digging a well. The performance of the Contract and tote amount due thereon were admitted. By way of counterclaim defendant, Thompson, alleged that the contract was. made with one Summerville arid) hot -with plaintiff, Kirk; toaifc at toe time of entering into' the contract defendant held and’ was- the owner of <a note for $60 executed' by Summer-ville to one Thompson; and that hue entered into the well contract to obtain, payment of Ithe .amount dhe on the note'. The defendant pleaded1 toe mote as fa counterclaim, and by his answer tendered in court toe .difference between) the amount due milder the contract and- toe amount due 011 toe' note, and offered to pay ciosts up to toe time of filing the answer. The reply denied the allegations of the 'aounteinclaim.
It appears finorni the evidence in the record, tolalfc 'some months prior to the negotiations -for the digging of the‘well Summerville had sold the well-digging' machinery to Kirk, hut that after such sale Summerville continued to take jobs and work with, the outfit as before toe stile. Kirk and Summerville testified that in conversations prior to the digging of toe well Thompson was informed of toe . sale to Kirk, and that Summerville was ■ assisting Kirk and teaching' him to. run the nig. The conversations with, reference to Idtoinig the work were with Sthnmerville. D'efendtint thereupon offered in eviil'enoe under his counterclaim the promissory nlcfe of Summerville1 with' proof of iite executódri,' assignment to Thompson, -and nonpayment. Appellant's assignments of error ore baiseidl wholly upon the exclusion of this .evidence.
Verdict for respondent for'the amount dUe’on the Contract *395for digging tole well. The trial count instructed toe julry as follows:
“There áte- mo controversy between toe panties in (this- case with reference to foie amtounit for which ytoulr verdict shoulid be ini ¡the e'vemlt toialt it is in flavor of toe plalimtiff. Tfhie controversy is ¡only with reference to wito whom. the dlefenidanlt, Mr. Thompson, made toe contract, whether Mir. Summerville, as he aonfcemds, ■or Mr. Kirk, as the latter contends. Sto if you find from, toe evidence thbit foe contract to do the wlell work himolved herein was 'between Mr. Thompson, the defendant, and Mir. Summer-ville, who formerly owtaed the outfit, Mr. Kirk Could not recover in this action, because Mr. Thompson’s 'lability would be to Mir. Sumlmiarviilfe, by whom he is not now being sued, but, on the other hand, if you finid -by a preponderance of foie evidence that toe contract, 'express! Pr implied, iwas nloit with Mr. Summerville, but with Mr. KHrk, Iasi he Contends, or that Mir. Thompson was. informed Mir. Kirk Was the owner of tole walhdrillinig outfit there toe first day, and ¡that he (Kirk) Was toe one who would collect for toe work to ble diotoe, anld tolat thereafter they went on and toe work was dtooie with that knowledge amid understanding, Mr. Kiirlc would be entitled to recover An thiiisl case.”
[i] It was pliai-nJtiff’s theory 'anld iwlas stated by his, counsel, in open court, that Summerville Was lacbing as agent for Kirk, who wa© foie principal in toe transaction wito Thompson. In his answer .appellant alleged, first, that Summerville (and molt Kiiirk was in fact the principal, anld1,, sedonid, tolat Kirk wais in fact toe principal, anld that appellant debit Wito Summerville without knowing or having reason to believe that Summerville was1 acting as agent for Kiirlc, and that upon toe latter theory the note was a valid counterclaim against Kirk, toe undisclosed principal who was suing upcln toe comlbraat. Civil Code, § 1691. Under the instruction given by toe ¡ferial court, tolat pfointiff cou'lld not reoovar if toe Contract was in fact between Summerville and1 Thompson, toe jury must have found tolat toe Contract wfasi in fact 'between Kirk amid Thoimpson. It is clear, however, under toe evidence and toe admission of plaintiff’s counsel at tíre trial, lamdNhe jury must have found, that the contract Was made by Sumlmierville 'a's agent of Kirk, and under siedtion 1691, Civil Code, whether Thompson was entitled to Coiuntardiaiiim Summerville’s mote in an action on *396the 'Qomteact 'by Kirk, the principa!), depended upon the question whether Thompson 'dealt with Summerville wilthbuit knowing or having reason to .believe that Summerville was acting as agent for Kiirk in> the transaction.
