(after stating the facts as above). The complaint is said to be demurrable on two distinct grounds: First, that the oral agreement to extend the life of the option is void as within the statute of frauds, so that there was no consideration for the defendant’s promise to do the assessment work; and, second, that, conceding the contract to be valid, the measure of the plaintiff’s damages was not the value of the mining claims which he lost.

If an agreement required to be in writing under-the statute of frauds is modified by a subsequent oral agreement, which does not in itself constitute a contract within the statute of frauds, the modification is valid and binding upon the parties; and it is generally held that, if the subsequent oral agreement is merely for a change in the time of performance of a written contract, it is valid. 20 Cyc. 287; Ward v. Matthews, 73 Cal. 13 , 14 P. 604 ; Scheerschmidt v. Smith, 74 Minn. 224 , 77 N.W. 34 ; Cummings v. Arnold, 3 Metc.(Mass.) 486, 37 Am.Dec. 155; Stearns v. Hall, 9 Cush.(Mass.) 31 ; Whittier v. Dana, 10 Allen (Mass.) 326; Hurlburt v. Fitzpatrick, 176 Mass. 287 , 57 N.E. 464 ; Kissack v. Bourke, 224 Ill. 352 , 79 N.E. 619 . Upon the doctrine of these decisions and the weight of authority, we are of opinion that the oral agreement set forth in the complaint in this case was not void as within the statute of frauds. If it was not void, it follows that there was no want of an adequate consideration for the promise of the defendant to do the assessment work on the mining claims. The consideration was the agreement of the plaintiff to waive the forfeiture and extend the time of performance of the contract for a period of 60 days.

As the demurrer was a general demurrer to the complaint for want of facts sufficient to constitute a cause of action, it is unnecessary to enter into a discussion of the question whether or not the facts which are set forth to show special damages are sufficient for that purpose, as in any view the plaintiff is entitled to recover damages in an amount *432 equal to the value of the annual assessment work which the defendant had promised to do upon the mining claims, and the burden of proof would rest upon the defendant to meet the allegations and proof of special damages by showing that the plaintiff might have saved himself from the loss arising from the breach of the contract by a trifling expense or with reasonable exertions.

The judgment is reversed, and the cause is remanded for further proceedings.

NOTE.

[a] (U.S.1901) Under Rev.St.Idalio, § 6007, which provides that no interest or estate in real property, other than leases for a term not exceeding one year, can be created or declared except by an instrument in writing, a written contract, giving an option to purchase real estate within a specific time, cannot be legally extended by a verbal agreement. — Lawyer v. Post, 109 F. 512 , 47 C.C.A. 491 .

[b] (Cal.1887) Defendant, not having the money to pay for lands purchased, obtained an advance from plaintiff. The title was taken in plaintiff’s name for his security, and it was agreed that the advance should be repaid within a year. The agreement was verbal, and, although it was agreed that it should be reduced to writing, this was never done. Before the expiration of the year plaintiff agreed to extend the time six months. Held, that the fact that the contract had never been reduced to writing did not prevent its enforcement, since it was intended to be performed within one year, and the extension had been made within the year. — Ward v. Matthews, 73 Cal. 13 , 14 P. 604 .

[c] (Cal.1896) Under the statute of frauds (Civ.Code, § 1624, subd. 6), requiring “an agreement authorizing or employing an agent or broker to purchase or sell real estate for compensation or commission” to be in writing, a valid extension of such a written agreement cannot-be made by parol. — Platt v. Butcher, 44 P. 1060 .

[d] (Ky.1903) Ky.St.1899, § 470, subsee. 6, provides that no action shall be brought to charge any person on any contract for the sale of real estate, unless in writing. A written contract for the sale of mineral rights in land provided for the payment of the consideration before a certain time, and that, if not paid, the contract should be void. The consideration not being paid at this time, the parties entered into a parol agreement extending the former contract. SelcL that, as the original contract was terminated by a failure to make payment as required, the parol agreement for extension of time was, under the statute, void because not in writing. — McConathy v. Lanham, 116 Ky. 735 , 76 S.W. 535 , 25 Ky.Law Rep. 971.

[e] (Me.1883) Where parties to a written contract for leasing a mill, the rent being a certain sum payable for each 1,000 feet of lumber that should be sawed at the mill during the term, made an additional agreement to shorten the term originally agreed upon, a person who in writing guarantied the first agreement and verbally assented to the second is not absolved from his liability upon the amended agreement by the effect of the statute of frauds. — Smith v. Loomis, 74 Me. 503 .

*433 [¶] (N.Y.1890) In an action for refusal to accept goods under a written contract of sale, which provided that the goods should be shipped and delivered within a certain period, it appeared that during that time the seller orally agreed with the purchaser to “carry” the goods for him for a reasonable time, and payment was not demanded, but no goods were set apart for or tendered him until after the expiration of the time specified in the original contract, and the goods finally set apart and tendered had not been shipped within that time. Held, that the oral agreement was either a modification of the written contract extending the time of delivery and date of payment, and required a tender of goods shipped within the contract period, or it was a new contract for the sale of other goods, rescinding the old one, and, being oral, was void under the statute of frauds, and plaintiff could not recover. — Clark v. Fey, 121 N.Y. 470 , 24 N.E. 703 , affirming (1880) 4 N.Y.S. 18 .

[g] (Ohio,1896) Where one purchased land, agreeing in writing that the vendor should have all timber suitable for lumber, to be cut and removed by á certain day, a subsequent verbal extension of the time by him for the cutting and removal was within the statute, and was not taken out thereof by the fact that the vendor relied on the extension, and delayed cutting the timber until after the original date specified. — Clark v. Guest, 54 Ohio St. 298 , 43 N.E. 862 .

[h] (Wis.1887) Where a writing, evidencing a contract for the purchase of lands, shows that the contract signed by one party is to be completed by an acceptance of the other party within a limited time, it is incompetent to show by parol evidence that the time for its completion by such acceptance was orally extended. — Athe v. Bartholomew, 69 Wis. 43 , 33 N.W. 110 .
