delivered the opinion of the court.
The only error assigned is the court’s denial of defendant’s request to instruct the jury as follows:
“I charge you that to excuse the performance of a contract the instrument itself must make some suitable provision for such nonperformance, for he could have provided against that in the contract.”
1. Though a bill of exceptions appears to have been settled and allowed, it does not accompany the transcript. This appeal was tried, pursuant to stipulation, upon an abstract which does not include any of the testimony received or of the instructions given.
The brief of respondents’ counsel contains statements as follows:
“Upon the trial of the case plaintiffs gave evidence tending to sustain the allegations of their complaint, and also tending to show that the work of laying said brick was done in rainy and freezing weather at the request of defendant, and that it agreed to assume the risk of the joints freezing if plaintiffs went ahead with said work in such weather, and that the officers and agents of defendant saw said work daily as it progressed, and knew *216said work was being done in freezing weather, and made no objections thereto, but were constantly urging plaintiffs to complete the same; that the walls of the building were not weakened by the freezing of the joints, and that the injury to the joints by freezing was due to the water-soaked and defective condition of the brick furnished by defendant for said work. The defendant gave evidence tending to show that said work was not performed in a workmanlike manner, and not according to the terms and conditions of the contract, and tending to show that said work was performed during freezing weather, and by reason thereof the mortar placed between the brick froze and joints in the wall fell out, thereby weakening said wall and impairing its value, and requiring additional work and expense upon the part of defendant to repoint said wall and to restore the same to good condition, or to such condition as the same would have been in had the work been performed in a good and workmanlike manner and according to the terms and specifications of said contract, and also tending to show that defendant never requested the plaintiffs to proceed with said work during freezing weather, and that defendant had never agreed to assume the risk of the joints freezing if plaintiffs would prosecute said work in such weather, and also tending to show that when defendant urged plaintiffs to hasten said work, plaintiffs declined on account of weather conditions, and also tending to show that, before and after the completion of said work, the defendant duly requested the plaintiffs to remedy the said defective condition in said walls arising from said freezing, but the plaintiffs refused to remedy or correct the same, and that thereupon the defendant was compelled to and did expend money and materials in correcting the same.”
The foregoing report of what is purported to have occurred at the trial in the lower court is not denied in the brief of appellant’s counsel, nor was the correctness of the narrative controverted in argument in this court except by asserting that the person who urged a .continuance of the work during the freezing weather was not such an agent as could bind the defendant by his *217solicitations or representations. In the absence of a bill of exceptions, and in want of any reference in the abstract to the testimony admitted, it will be taken for granted that the declaration quoted, which pretends to have been extracted from the bill of exceptions, correctly details what transpired at the trial.
2. A liberal interpretation of the averments of the complaint would permit the admission of testimony tending to show that defendant’s agents requested plaintiffs to lay the brick, notwithstanding the rigor of the weather, inspecting the work as it was performed and agreeing to accept it when completed.
3-5. The parties were entitled to have their respective theories submitted to the jury, but, as the hypothesis of each was so variant, it was impossible to accept as true the assumption of both. As an abstract legal proposition the requested instruction, though very meager in details and wholly lacking in consequences' which would follow if a finding were made in conformity therewith, might possibly have been applicable in some instances to the facts involved. If parties stipulate for the performance of a valid contract, a failure to comply with its provisions will not excuse him who assumed the obligation unless an observance of the terms of the agreement has been rendered impossible by the act of God, the operation of a subsequent law, or the conduct of the other party. Bishop, Cont. (2 Enlarged ed.) § 590; 2 Parsons, Cont. (9 ed.) *672; Pengra v. Wheeler, 24 Or. 532 (34 Pac. 354; 21 L. R. A. 726) ; Hanthorn v. Quinn, 42 Or. 1 (69 Pac. 817) ; Reid v. Alaska Packing Co., 43 Or. 429 (73 Pac. 337).
The original agreement referred to herein contained no provision exempting plaintiffs from performnig their part of its terms on account of severe weather. The most solemn written contract, except when prohibited by positive enactment, may be modified or annulled by a *218subsequent valid oral agreement. If, therefore, the defendant’s duly authorized agent, desiring a speedy completion of the building, requested a construction of the walls during freezing weather, agreeing to assume the risks incident thereto, and plaintiffs, relying thereon, complied with the solicitation, the original contract was modified in that particular by the subsequent oral agreement entitling them to the remainder of the price agreed upon.
The defendant, having introduced testimony tending to disprove any modification of the written contract, could have formulated an instruction illustrating its theory of the case. Assuming that the jury were charged as to plaintiffs’ hypothesis respecting an alteration of the original agreement, such postulate must have been found inapplicable before a finding could have been made for the defendant, and hence the request might have been, in substance, as follows:
“If, however, you should find that no subsequent agreement was made, or if you should find that a modification of the written contract was attempted, but that the person assuming to act for the defendant, in requesting a speedy completion of the walls, and assuming all liability on account of injury from freezing, was unauthorized to represent the defendant, in either of such cases you should award it such a sum of money as would equal the damages sustained by it, not surpassing $925, and, if such allowance exceeds $832, your verdict should be in favor of the defendant for the difference, but, if you should find that the damages' so suffered did not equal the sum admitted to be due plaintiffs, your verdict should be in their favor for the difference.”
The requested instruction does not include the conditions mentioned nor the consequences depending thereon, and, failing in these particulars, no error was committed as alleged.
It followed that the judgment should be affirmed, and it is so ordered. Affirmed.
