Me. Chief Justice Loed
delivered the opinion of the court:
1. Preliminarily, it is claimed that the trial court failed to make certain findings of fact which the pleadings show were material and necessary. If that is so, the defendant should have applied to the trial court to make such findings, and if it refused, he could have excepted to the ruling, and brought the matter in an appropriate way to the attention of this court. “Should the circuit court fail or neglect,” said Thayer, C. J., “to make a material finding upon the evidence before it, and the bill of exceptions showed that the .court was specially requested to make the finding, and it had refused to do so, this court would doubtless deem an exception to such refusal well taken”: Hicklin v. McClear, 18 Or. 138 (22 Pac. 1057). As the findings of fact by the trial court are conclusive upon this court, the judgment must be affirmed, unless such findings are insufficient to sustain it.
*482The important question of fact to be determined was whether the consideration for the alleged written agreement was based on an existing indebtedness of five hundred dollars for a balance due from the defendant to the plaintiff on the purchase price of the Stephens Ranch, which the plaintiff sold to him. It is alleged in the complaint that the plaintiff sold and conveyed to the defendant certain real property known as the Stephens Ranch for the agreed price of two thousand dollars; that the defendant paid thereon the sum of one thousand five hundred dollars, and that he executed and delivered to the plaintiff the written agreement set out to pay the balance of five hundred dollars. The defendant denied these allegations, thus forming an issue which rendered the defense of a want of consideration unnecessary; for, if the indebtedness actually existed as the basis, or formed the consideration, of the written agreement at the time of its execution and delivery, it would defeat the defense set up that such agreement was without consideration, or á mere promise to make plaintiff a present of five hundred dollars if the defendant should succeed in selling the property for two thousand five hundred dollars. The court found, in substance, that at the time alleged the plaintiff sold and conveyed to the defendant certain real property known as the Stephens Ranch for the agreed price of two thousand dollars; that the defendant paid one thousand five hundred dollars of such purchase price, leaving a balance of five hundred dollars due and unpaid; that at the time alleged, the defendant, being indebted to the plaintiff in the sum of five hundred dollars as a balance due on said purchase price, delivered to her the said written agreement, and that more than seven years elapsed between the execution of the written agreement and the commencement of the action; so that it appears from the facts as found by the court that when the written agreement was executed and delivered to the plaintiff, the defendant was *483actually indebted to her in the sum named, as a balance due and unpaid on the purchase price of the ranch, and that such indebtedness formed the consideration of the agreement. This result fully sustains the allegations of the complaint upon which issue was joined, and renders futile and unavailing the contention of the defendant, unless the conclusion of law which the court deduced from its findings of fact is unwarranted and erroneous. The court found as a conclusion of law that the written instrument was an agreement or promise to pay the plaintiff the sum of five hundred dollars within a reasonable time, and that the seven years which had elapsed prior to the commencement of the present action is a reasonable time. The real question, then, to be determined, is the construction which should be given to the written agreement under the pleadings and findings of fact. Under the facts found, the the agreement did not create the indebtedness, but postponed the time of payment of a debt then due to an uncertain future time. The agreement of the defendant is “to pay the sum of five hundred dollars unto Delia Noland when the sale of the property known as the Stephens Ranch shall be accomplished * * * for not less than two thousand five hundred dollars”; and not that the defendant will pay such amount if he succeeds in selling the ranch for such price. The five hundred dollars was an existing indebtedness at the time the agreement was executed by the defendant and accepted by the plaintiff, the effect of which agreement was to postpone or defer the time of payment of an already due and existing debt to an uncertain date, dependent upon the accomplishment of a specified transaction, namely, the sale of the Stephens Ranch at the price mentioned.
2. yhere there is a present debt then due, constituting the basis of an agreement which merely postpones the time of its payment to an uncertain future date, when a certain specified transaction shall be aceomphshecTpEhe *484agreement is to pay within a reasonable time whether ^such transaction is accomplished or not. In Crocker v. Holmes, 65 Me. 195 (20 Am. Rep. 687), it was held where the maker of a note promises to pay a certain sum when he shall sell the place he lives on, that the debt is absolute, though its payment maybe postponed; — that it is the duty of the maker to sell within a reasonable time that he may discharge his indebtedness, and that he cannot avoid liability by putting it out of his power to perform his contract. Appleton, J., in announcing the opinion of the court, said: “ It is claimed that the debt will never become payable, and can never be enforced. The maker of the note promises to pay when he shall sell the place he lives on in Oxford, Maine. The debt is due in presentí. Its payment is at a future time, but the debt none the less exists. The debt is absolute, the time of payment indefinite. * * * The maker of the note is to sell within a reasonable time, to enable him to discharge his indebtedness.” In DeWolf v. French, 51 Me. 420, it was held that where a debt is due absolutely, and the happening of a future event is fixed upon as a convenient time for payment merely, and the future event does not happen as contemplated, the law implies a promise to pay within a reasonable time. In Nunez v. Dautel, 19 Wall. 562, the agreement was “ to pay as soon as the crop can be sold, or .the money raised from any other source,” and it was held payable in a reasonable time. Mr. Justice Swayne said: “ It could not have been the intention of the parties that if the crop were destroyed, or from any other cause could never be sold, and the defendants could not procure the money from any other source, the debt should never be paid. Such a result would be a mockery of justice.” In Ubsdell v. Cunningham, 22 Mo. 124, the instruments were made payable “as soon as collected from my accounts at P.,” etc., and they were held promissory notes, and not mere conditional obligations, and that they were *485payable within a reasonable time, or as soon as all was collected that could be. In Sears v. Wright, 24 Me. 278, the condition was, “from the avail of logs bought of M. when there is a sale made.” Held, payable in a reasonable time. The court said: “ By the terms of that contract it could not be inferred that the plaintiff had consented to subject himself to such contingency (that is, that the logs could not be sold). His agreement in terms was to wait till the logs could be sold; and thus the defendants had a duty to perform. They were bound to sell the logs, and to do it within a reasonable time ”: Hicks v. Shouse, 17 B. Monroe, 483; Williston v. Perkins, 51 Cal. 554; Randall v. Johnson, 59 Miss. 317 (42 Am. Rep. 365).
The defendant promises to pay the five hundred dollars when the sale of the property shall be accomplished for a specified sum. There is a present debt, but its payment is postponed to a future time; yet the debt nevertheless exists. The defendant promises or undertakes to sell the property for the sum specified that he may discharge his indebtedness, and if he fails to do so, or is unable to sell the property, such indebtedness becomes due and payable within a reasonable time. As the findings show that the’ indebtedness existed and was due, and that its payment was postponed to a future uncertain date by the acceptance of the agreement, which operated not to create the debt, but to extend the time of its payment for a reasonable time, whether such sale should be accomplished or not, it results that the findings are sufficient to support the judgment which must be affirmed.
