This is a suit for the recovery of the sum of one hundred and seventy-five dollars, being the amount paid by plaintiff on the execution of an alleged contract for the purchase of some town lots in the town of Ensenada, Lower California. It is alleged in the complaint, filed before a justice of the peace, that defendant failed to carry out his contract to convey the property and plaintiff prayed judgment for return of the advance payment. In his answer, defendant set up, in substance, that the instrument or receipt upon which plaintiff sued was only a memorandum or receipt for the $175, was not the real contract for purchase of the real estate, ■and that after said receipt was given the plaintiff and one Sloane signed a formal contract for purchase and sale of the *628lots; that said contract between Sloane and plaintiff became a substitute for tbe original receipt, which -then ceased to be of any further binding force or effect. At the trial in the circuit court the plaintiff had a verdict and judgment for the amount sued for and defendant appealed.
I. On facts that are undisputed in this record, the plaintiff can not recover, and the trial court should have given a peremptory instruction for defendant. So far' as is necessary to state, the facts are as follows:
In October, 1887, one W. A. Sloane, then residing in southern California, placed in the hands of defendant Whitney for sale some lots in one of the “boom” towns of that country. Sloane had laid off an addition to Ensenada, and it seems had taken Whitney in as a partner — either by virtue of the payment of part of the consideration or for services to be performed in making sales. Whatever that arrangement was, is not material to this controversy. It is now sufficient to say that Whitney negotiated a sale of three of these lots to the plaintiff, Mrs. McClurg, the latter acting through Dr. Mc-Clurg, her husband. Whitney was not posted as to the numbers of the unsold lots, but McClurg agreed to give $350 for three of them, one of which was to be a corner lot, and thereupon one-half the purchase price was paid and Whitney gave the following receipt:
“Carthage, Mo., Oct. 17, 1887.
“Received of Effie D. McClurg one hundred and seventy-five dollars ($175), which is one-half payment for three lots one of which shall be on the corner of a block and which are located in the parcel of land known as the Sloan & Whitney addition of Ensenada, in Lower California. The remaining one-half payment is to be made in six months when the undersigned contracts to convey by proper deed to the said- Effie D. McClurg the three lots as aforesaid.
“L. E. Whitney.”
Without dispute, the evidence shows that immediately *629on the payment of the $175 mentioned in the above receipt, defendant Whitney sent the money with a letter of advice to Sloane in California, and he, Sloane, at onoe executed in duplicate and returned to Whitney a formal binding contract, which was received by Whitney at Carthage and which was presented' to the plaintiff, Mrs. McOlurg, who signed the same, keeping one copy and returning the other to Sloane. That formal contract for the sale of the lots was as. follows:
“This Certificate and Agreement, made and entered into this first day of November, 1887, at San Diego, California, in consideration of the payments hereinafter mentioned, Witnesseth, that Effie D. McOlurg has this day contracted with W. A. Sloane for the purchase of lots Nos. 11, 12, 13, 14 in Block No. Three (3) in Sloane & Whitney’s Subdivision of 6 1-4 acres, lots No. 288,289 and 290 of the town of Ensenada, Lower California, Mexico, according to the official map thereof on file in the office of records in said town, for the sum of $350, of which sum $175 has been paid. The balance thereof, $175, to be paid to the said W. A. Sloane, at his office in San Diego, California, or to his authorized agent at Ensenada on or before six months from this date, with interest at the rate of eight per cent per annum.
“On receipt of said deferred payment and interest, in accordance with the above stipulation, the said W. A. Sloane agrees to execute and deliver to the said party or his assigns, a good and sufficient title deed to the above described property.
“In witness whereof, we have hereunto signed our names the day and year above mentioned.
“W. A. Sloane.
“Effie D. McOlurg, Purchaser.”
Like many other real estate ventures of that period the “bottom fell out” of Ensenada and the property became almost valueless. Nearly ten years after the above transaction plaintiff met defendant Whitney, and after some talk *630as to whether a deed could be had to the property, and Whitney advising the plaintiff that the property was of very little value, that it was not worth the amount of the deferred payment, etc., plaintiff thereupon demanded of the defendant the return of the $175 which she had advanced on the purchase. This being refused, this action was brought with the result before stated.
At the trial, Dr. MeClurg was allowed to give his opinion as to what he considered the legal import of the two instruments of writing quoted above. And though he testified in cross-examination that “when this receipt was taken Dr. Whitney told him he Whitney) didn’t know what lots he (MeClurg) would get and that he (Whitney) would write toSloaneand have him sign the papers and send them out here (to Carthage) so he (MeClurg) would know what he would get and that the paper came and his wife signed it,” etc. He (MeClurg) gave it as his understanding that the formal contract, received and signed by Sloane and Mrs. MeClurg, was of no consequence or binding force except to furnish a description of the property purchased, and that the original receipt signed by Whitney was the sole .and only contract between the parties.
This testimony of Dr. MeClurg was clearly incompetent. The construction of these writings was a matter for the court and not for the witness. In the absence of fraud or imposition (and of this there is not a shadow of suspicion) parties are bound by their written agreements. The contract dated November 1, 1887, is clear and complete and fully covers every feature of the transaction. It is impossible to give that contract full force and effect without assuming that it was executed in pursuance of or as a substitute for the memorandum made two weeks prior thereto. Everything that was, said or done prior to the execution of the formal contract of November 1 became merged in the terms of the latter, and it alone became a memorial-of the contract between the parties. *631It is well-settled law, that a 'contract in writing which is complete and perfect in itself and not ambiguous in its terms, will be held to supersede a prior written contract in relation to the same subject-matter, and parol evidence-will not be admitted to show that such was not the intention of the parties. Chrisman v. Hodges, 75 Mo. 413. It is also the settled rule “that a valid contract made in substitution for one of a prior date, annuls the obligation of the former”. Pressed Brick Co. v. Barr, 76 Mo. App. 380, and authorities cited.
II. It is manifest upon the face of the papers that the writing of October 17 was given as a mere receipt for the money paid and as a memorandum to hold good until a good and sufficient contract should be executed by Sloane in whom the title was supposed to rest, and that the writing of November 1 was intended as the one and only binding contract for the purchase and sale of the property. The paper first executed was not in fact a good and enforcible contract for the sale of real estate since it failed to describe the property, while the writing last signed and executed by Sloane and Mrs. McOlurg was perfect and complete in all respects. It would then be absurd to hold that the parties intended the informal and incomplete memorandum or receipt of October 17 as the contract, whereas they subsequently signed another which was in every respect complete and sufficient.
The trial court not only erred in admitting the above recited testimony, but erred also in submitting the interpretation of these writings, as well as their legal import, to the jury, as was done by instructions given at plaintiff’s request. These were matters properly for the court and not the jury. Michael v. Ins. Co., 17 Mo. App. 23; Taylor v. Fox, 16 Mo. App. 527. Since then the record shows that the alleged contract on which this suit was brought had been abrogated and supplanted by another, it must follow that no action can be maintained on the former. The judgment then, which was for the plaintiff, must be reversed.
The judges all concur.
