This is an appeal from a judgment of the United States District Court for the District of Colorado, awarding damages to appellee Gaffney for the failure of the appellant Tenneco Oil Company to give notice that an oil and gas lease, which Gaffney had assigned to Tenneco, would be permitted to terminate for failure to pay rentals when due.
On November 1, 1963, Gaffney acquired a Federal Oil and Gas Lease on 1536 acres of public domain in Campbell County, Wyoming. The lease provided, in part:
“If there is no well on the lease lands capable of producing oil or gas in paying quantities, failure to pay rental on or before the anniversary date shall automatically terminate the lease by operation of law.”
The lease further provided:
“The lessee may surrender this lease or any legal subdivision thereof by filing in the proper Land Office a written relinquishment, in triplicate, which shall be effective as of the date of filing subject to the continued obligation of the lessee and his surety to make payment of all accrued rentals and royalties and to place all wells on the land to be relinquished in condition for suspension of or abandonment in accordance with the applicable lease terms and regulations.”
Gaffney thereafter assigned to Tenneco a portion of the lease covering 720 acres. The assignment provided:
“If Assignee or his assigns wishes to relinquish this lease at any time, he must offer reassignment to Assignor at least sixty (60) days before any rental due date or final lease expiration date, whereupon, if Assignor wishes to regain the lease, Assignor must give notice to Assignee within thirty (30) days of receipt of Assignee’s notice.”
*308 In July of 1964, Tenneco drilled a test well to a depth of 5814 feet. No oil or gas was discovered, whereupon Tenne-co determined that the area, including that portion obtained from Gaffney, was valueless. Without notice to Gaffney, Tenneco allowed the lease to terminate on November 1, 1964 for non-payment of annual rentals. Upon demand from Gaff-ney, Tenneco unsuccessfully attempted to regain a lease on the property for Gaff-ney. Thereupon Gaffney brought this action, alleging damages caused by Ten-neco’s failure to give the 60 days notice required in the assignment. There was no issue of fact as to Tenneco’s liability, and the trial court sustained plaintiff’s motion for summary judgment, holding that the notice of relinquishment provided for in the assignment, as a matter of law obligated Tenneco to give notice that the lease would be permitted to terminate for failure to pay annual rentals.
Tenneco argues that in determining its contractual duty to give notice, the meaning of the word “relinquish”, as used in the assignment, should be the same as that in the lease and the Federal Regulations where relinquishment of a lease requires affirmative action on the part of the lessee and is distinguished from automatic termination because of failure to pay rentals. We agree with the trial court that the provision in the assignment should not be so narrowly construed.
Ordinarily, the construction of a contract presents a question of law. United States v. Continental Oil Co., 10 Cir.,
The trial court held that Gaffney’s damages were “not limited to the value of the leasehold interest and overriding royalty at the date of defendant’s breach of contract, but are based upon the highest value of the leasehold interest from the date that plaintiff acquired the lease from the United States Government to the date of the commencement of this action.” Shortly after the termination on November 1, 1964, a noncompetitive lease was issued to Jack G. Ladmer, effective January 1, 1965. Lad-
*309
mer assigned it to Hal A. MeVey on December 2, 1964, effective January 1, 1965, for a consideration of $8.00 per acre and a 3% overriding royalty. On December 4, 1964, MeVey assigned the lease to HLM Drilling Company, effective January 1, 1965, for $8.00 per acre and an additional overriding royalty of 1%. By assignment dated February 11, 1965, effective April 1, 1965, the drilling company conveyed the lease to Allied Chemical Corporation for a consideration of $15.00 per acre and an additional
1%
overriding royalty. This conveyance was the last lease acquired by Allied Chemical to complete a drilling block. During the period = preceding the drilling by Allied Chemical, Gaffney had assigned other portions of his original lease for $5.00 per acre with 3 and 3y2% overriding royalties. One of these assignments was to Allied Chemical in May of 1965.

In determining that the measure of damages was the highest price which had been paid, prior to the commencement of this action, for the leasehold interest in question, the court reasoned that if Ten-neco had not breached its contract, Gaff-ney “would have had opportunity to assign the lease for $15 an acre, and reserve a 5% overriding royalty.” No finding was made as to the market value of the leasehold on the date of the breach. The price for which Gaffney would have sold the lease had there been no breach of the contract by Tenneco — if he would have sold it at all — is pure speculation and not the measure of his damages. While we have not found that the Wyoming Supreme Court has considered this precise question,

we think, however, that it has indicated that Gaffney’s recovery should be determined as of November 1, 1964, the date of Tenneco’s breach of the contract. In Redwine v. Fitzhugh,
“As a general rule, of course, the measure of damages for the loss or destruction of personal property is its market value at the time of loss, if it has a market value.”
An additional guideline is found in the analogous situation where a vendor, by reason of failure to convey, breaches an executory contract for purchase of real property which has appreciated in value. The applicable Wyoming rule has been stated as follows:
“Where damages are sought for the refusal or failure to sell land pursuant to the terms of a contract for a stipulated price, the measure of damages, in the absence of an agreement to the contrary, is the difference between the contract price and the value of the land at the time appointed for the completion of the sale.”
Francis v. Brown,
“The proper measure of damages was the value of the property at the time the deed ought to have been delivered * -X- # >>
Furthermore, we are mindful of the general principle that only those damages which are the natural and reasonably foreseeable result of a breach of contract are recoverable. Schlottman v. Pressey, 10 Cir.,
The trial court allowed interest from November 1,1964 on the amount of damages awarded. Tenneco contends that, under Wyoming law, the damages sued for were unliquidated and interest was not allowable prior to the entry of judgment. The Wyoming Supreme Court has followed the general rule that interest is not allowable on unliquidated damages. Hancock v. Johnson,
The judgment is reversed and the case remanded for findings consistent with the views herein expressed, each party to pay its own costs.
Notes
. The court found: “In making the assignments to defendant H. L. Spearman and Allied Chemical Corporation, plaintiff believed after being advised by experts that $5 per acre was the ‘going’ price for oil and gas leases in the Olmstead Creek area.”
. The parties are in agreement that the instrument sued on is a Wyoming contract and controlled by Wyoming law.
