Appeal from the district court of Renville county, North Dakota, Honorable K. E. Leighton, Judge.
This action is one of specific performance wherein the plaintiff seeks to have the defendant perform a certain alleged contract claimed by the plaintiff to have been made between defendant and plaintiff with reference to the N. E. ¼ of section 21, township 162, range 86, Renville county, North Dakota. Plaintiff claims that he is entitled to conveyance of said premises from the defendant to the plaintiff upon the payment by the.plaintiff to the defendant of the purchase money according to the terms of the contract. The facts in the case are as follows:
On the 7th day of April, 1916, the defendant was the owner of a certain tract of land above described. The defendant is a resident of the city of St. Paul, Minnesota. It is claimed by the plaintiff, that on the 7th day of April, 1916, the defendant made an offer, in writing, to sell the land in question to the plaintiff for $3,200, the terms of such sale to be as follows: $250 when the deal is closed, $250 per year, after the year 1916, payable January 1st of each year, and the balance, at the end of five years, to then become due and payable; interest on deferred payments to be at the rate of 6 per cent per annum, payable semiannually, the first interest payments to be made October 1, 1916, and every six months thereafter. Plaintiff claims that on the 14th day of April, 1916, and before said offer to sell was withdraAvn by the defendant, the defendant’s offer to sell such land to the plaintiff was accepted, which acceptance in Avriting Avas communicated to the defendant and received by him about the 17th day of April, 1916. After acceptance by the plaintiff of defendant’s offer was communicated to and received by the defendant, the defendant notified the plaintiff, in writing, that he would not perform his part of the contract. The plaintiff asserts, he is ready, able, and willing *566to perform his part of the contract. Defendant refuses to make any conveyance of said land. The contract, if any, is in the form of letters exchanged between the plaintiff and defendant.
The action is maintained upon the theory, and the complaint is framed in pursuance of the theory, that the defendant made an offer, in writing, to sell the real estate in question for a specific price and upon specific terms; and that the plaintiff made an unconditional acceptance, in writing, of such offer, claiming thereby to have made a binding contract for the purchase of said land. It is a principle of law, well established and understood, in the law of contracts, that where one, by letter, makes an offer to sell property for a specified price and upon specific terms and there is an unqualified and unconditional acceptance of the offer, the mutual letters thus -written make and constitute a contract in writing. It is also a well-settled principle of law that in thus construing such letters to constitute a contract, there must be no deviation from the terms of the offer in the letter accepting the terms of the offer. The letter of acceptance must contain no new or different proposition, which would, to any degree, change the terms of the offer. When an offer is made as above stated, the acceptance must contain no conditions which add to the terms of the offer. By this rule the transaction in question-must be measured.
However, the terms of the contract, or the terms of the offer and the acceptance thereof, must be distinguished from matters which relate not to the terms of the contract, but to the execution and performance of the contract. This distinction is of importance where contracts are made as a result of correspondence. After setting forth the correspondence which is the basis of the contract in question, we will endeavor to point out the distinction as it applies to this case.
The entire correspondence is as follows: Kvale testifies he had some correspondence with Daniel Keane, — that he wrote a letter to him on March 17, 1915. He testified that he had no copy of the letter nor the original, but that he wrote and asked him if he would sell the land. To the letter written March 17, Kvale testifies he received a reply which is exhibit 2, which came inclosed in exhibit 1, the envelop. The envelop is postmarked at St. Paul, Minnesota, March 24, 1916. In the upper left-hand corner is the conceded address of *567the defendant, “642 Ingiehart avenue, St. Paul, Minnesota.” The address on the envelop is “Mr. Neis Kvale, R. F. D. No. 2, Tolley, North Dakota.” ' ' '
Exhibit 2 reads as follows:
St. Paul, Minnesota. 3/23 — 16.
Mr. Neis Kvale,
R. F. D. No. 2,
Tolley, North Dakota.

The plaintiff testifies that he wrote an answer to exhibit 2, addressed to Daniel Keane at 642 Inglehart avenue, St. Paul, Minnesota, and deposited the same in the mail; that he received a letter marked exhibit 4, which came in the envelop marked exhibit 3. Envelop is postmarked St. Paul, Minnesota, April 10, 1916. In the upper left-hand comer, it contains the following words: “642 Inglehart avenue, St. Paul, Minnesota.” The envelop is addressed to Mr. Neis Kvale, Tolley, North Dakota.

In reply to this letter, plaintiff testifies he received the following letter:
Exhibit 6.
St. Paul, Minnesota, April 17, 1916.
Mr. Neis Kvale,
Tolley, North Dakota.
Dear Sir:—
Your letter was received by me this morning inclosing a cheek for $10 which I herewith return to you, as I have already sold my property, and will say that you were too slow in answering my letter. If you had answered it about five days ago the sale would have been made. Therefore, having sold the property, I return your check.
Yours very truly,
Daniel Keane.
It must be conceded that the terms of the contract are: The price of the land, the amount of the initial payment, and the subsequent payments to be made yearly, the time when the payments should be made, the rate of interest, the taxes, and the proposition to take a mortgage, which was evidently what the defendant meant in his reference to a mortgage in his letter of April 7th. These terms are definite and certain. There is no room for doubt as to what they mean. The plaintiff in his reply letter accepts all of such terms. Attention is called to his language in this letter: “I hereby agree to pay you the said price as per your terms stated in your letter,”— then follows the balance of the letter. It will be seen there are no new terms suggested, no change in the terms demanded, but an absolute acceptance of the terms as stated by the defendant. The other matters referred to in plaintiff’s reply as to the making out of the contracts in duplicate which he asked the defendant to make out and send to him, and which he would sign and return a copy, together with the balance of the first payment of $240 — all related to the execution and *570performance of the contract, and did not relate to the making of the •contract or the terms thereof. The making of the contract and execution and performance must be distinguished. The making of the •contract, if it were made, was completed between the plaintiff and defendant when the plaintiff had quoted his price and terms in the manner in which he did, which price and terms were unreservedly accepted by the plaintiff. After this would come the execution of the contract which had been made. While the letters of themselves constitute the contract so far as to be binding between the parties, and are effective for the purpose of showing an actual meeting of the minds of the parties in the contract, and are sufficient to take the matter without Statute of Frauds, the plaintiff had the right to assume that the •defendant would desire to have the contract executed in a more durable form and in accord with the ordinary custom of having the same put in the form of a contract for deed. When the defendant made the price and terms in the manner in which he did, he necessarily impliedly obligated himself to complete the sale of the land by reducing the terms to the form of the ordinary contract, or, in other words, to place such words in a permanent form so as to protect both himself and the buyer.
That part of the plaintiff’s letter which refers to the payment of the $10 and the payment of the $240 after plaintiff had signed and returned a copy of the contract related to the performance of the contract, ánd, in no manner, changed the terms stated by the defendant. As it appears to us, if the defendant made the contract, it is his duty to enter into a contract or execute a conveyance which would contain the terms enumerated by him. It might not be the duty of the defendant to make such contract any more than that of the plaintiff, but it certainly constitutes no change in the terms of the contract for the plaintiff to request the defendant to draw such contract in duplicate.
We are of the opinion that the correspondence taken as a whole is insufficient to constitute a contract whereby the defendant sold the land in question to the plaintiff upon the terms stated in the letters .of the defendant, and insufficient to show that the plaintiff purchased .such land upon such terms provided ; the correspondence, as introduced in the case, was incompetent evidence; and, further, there was no contract, for the reason that the defendant had insufficient capacity *571'to enter into the contract. As to the question whether the letters were properly admitted, in evidence, and as to whether there was a sufficient-foundation laid for the introduction of the letters in evidence, we are of the opinion that no proper foundation was laid for the introduction in evidence of such letters, and that they were improperly admitted as evidence. The general rule applicable in this case is that laid down in § 2153, volume 3, Wigmore on Evidence, and reads as follows: “When a letter is received by due course of mail, purporting to come in answer from the person to whom a prior letter has been sent, there are furnishéd thereby, over and above mere contents showing knowledge of facts in general, . . . three circumstances evidencing the letter’s genuineness: First, the tenor of the letter as a reply to the first indicates a knowledge of the tenor of the first. Secondly, the habitual accuracy of the mail in delivering a letter to the person addressed and to no other person, . . . indicates that no other person was likely to have received the first letter and to have known its contents. Thirdly, the time of the arrival, in due. course, lessens the possibility that the letter, having been received by the right person but left unanswered, came subsequently into a different person’s hands and was answered by him. To this may be added the empirical argument that in usual experience the answer to a letter is found in fact to come from the person originally addressed. There seems to be, here, adequate grounds for a special rule declaring these facts, namely, the arrival by mail of a reply purported to be from the addressee of a prior letter duly addressed and mailed, are sufficient evidence of the reply’s genuineness to go to the jury.”
The author uses this further language in commenting upon this principle: “Such a rule, varying slightly in the phraseology of different judges, seems now to be universally accepted.”
In the case at bar, there was no jury, but the rule applies with equal effect. A material question to be first answered is: When is a letter proved to have been sent or mailed, so that such proof of sending or mailing will be a foundation authorizing the admission in evidence of a reply letter thereto ? We are of the opinion that it is the general rule that where a letter is offered in evidence, which letter is claimed to be an answer to a previous letter, before such letter which is the answer can be received in evidence, there must be proof that the pre*572vious letter was written or mailed. National Acci. Soc. v. Spiro, 24 C. C. A. 334, 47 U. S. App. 293, 78 Fed. 774. If it is shown that the previous letter is written and mailed in the usual and regular manner, with sufficient postage prepaid, the reply received in due course of the mail may be treated as prima facie genuine. The statement in a letter offered, that it is in answer to a letter previously received, does not of itself make the letter admissible. To so hold would dispense with the necessity of proof of the writing and mailing of the previous letter, and will also make the letter the proof of its own genuineness. This would not be the proper method of proof, and is not permissible. Smith v. Shoemaker, 17 Wall. 630, 21 L. ed. 717; Butterworth & Lows v. Catchcart, 186 Ala. 262, 52 So. 896.
This is one rule by which the genuineness of correspondence may be proved, but when proof is sought to be made under this rule, strict compliance with the requirements of the rule is necessary.
Another method of proof in such cases is to prove the genuineness of the letters, or, in other words, to properly authenticate them. For instance, if a letter has been written, direct proof that the letter was received by the person to whom it was addressed, and if a reply is received to such letter the genuineness thereof proved by showing that the signature to such letter is the genuine signature of the person who wrote it.
The plaintiffs have sought to establish their claim by the first method, and, in order to permit proof based upon the correspondence entirely, he must bring himself strictly within this first rule. It is certain that the rule should not be extended. To do so would afford too great an opportunity for fabrication and undue advantage. We are of the opinion that, where a person undertakes to show that he sent another a letter by mail, no presumption will arise that the letter so sent was received by the person to whom it was addressed unless it is shown that it was deposited in the postoffice or some department thereof, as, for instance, in a mail box on a rural route, and that such letter was properly addressed and stamped with sufficient postage. Trezevant v. Powell, 61 Tex. Civ. App. 449, 130 S. W. 234. It is conceivable that a person could write a letter to another and deposit it in the postoffice without stamping it and without placing sufficient postage thereon, and truthfully claim that he had addressed the letter *573to tbe party at his proj^ or address and deposited it in the United States mail. In order for a reply to a letter written to have a proper foundation for its admissibility laid, it must first appear that the letter written was properly addressed to the party at his known or usual address and properly stamped with the requisite amount of postage thereon and deposited in the postoffice or in some department thereof authorized to receive letters for the purpose of forwarding them to the parties to whom they are addressed. Has the plaintiff brought himself within this rule ?
We think it advisable to quote some of the testimony in this regard:
Q. Mr. Kvale, did you have some correspondence with Daniel Keane ? ......
A. Yes.
Q. State whether or not you wrote him a letter on March 11, 1915.
A. Yes.
Q. Have you a copy of that letter?
A. No.
Q. Have you the original letter?
A. No.
Q. Do you remember what you wrote about?
A. Yes.
Q. What did you write about?
A. I wrote and asked him if he would sell the land.
Q. What land?
A. If he would sell the quarter of land 160 — 21, about how much he would take for that. (The township and range named in this answer are evidently erroneous.)
Q. Do you remember whether that had reference to the N. E. ¼ 21-162-86 ?
A. Yes, sir.
It will be observed that this is the initial letter of the alleged transaction. It must also be observed that the plaintiff does not testify that such letter was addressed to the defendant at his known or usual address, or that such letter was deposited in the United States mail or in the postoffice or any department thereof authorized to receive such *574letters, or that the postage was paid or the letter properly stamped,, in accordance with the rules of the United States postal laws and regulations. It appears to us, the proof must be thus first made before-there is any proper foundation laid for the introduction of a reply of such letter. The proof explicitly showing that no such foundation-, was laid, the alleged reply to such letter was entirely inadmissible-though the reply may have been received in the customary way through the United States mail.
Further testimony of the plaintiff is as follows:
Q. Did you write a letter in answer to this and exhibit 2 ?
A. Yes.
Q. Addressed to Daniel Keane at 642 Inglehart avenue, St. Paul?
A. Yes.
Q. Did you deposit it in the mails ?
A. Yes.
Q. After that did you receive any further letters from Daniel Keane ?
A. Yes.
Q. I show you exhibit 3 and ask you whether you received that envelop in the mail ?
A. Yes.
Q. Along about the 10,th to the 15th of April ?
A. Yes.
Q. I show you exhibit 4 and ask you whether or not that is the letter contained in the envelop marked exhibit 3 ?
A. Yes.
Q. And you received this letter in the United States mail ?
A. Yes, sir.
It will be observed that the plaintiff, in the letter which he testifies he wrote in answer to exhibit 2, does not show that such letter was stamped with sufficient postage, hence there is no presumption that the same was delivered to the addressee. The plaintiff having not shown that such letter was stamped with the proper amount of postage, for aught that appears in the testimony, the plaintiff might have written the letter and deposited it in the United States Postoffice without *575the proper stamps or postage thereon, and, if so, the letter would not be delivered, and at all events it is certain there could arise no presumption of its delivery, and there is no foundation laid which would' admit in evidence a reply to such letter. Further, in reference to the letter claimed to be written in answer to exhibit 2, the letter itself is. not in evidence, neither is there any copy thereof in evidence, and there is no testimony as to what the contents of that letter was.
We think it must conclusively appear there is no foundation for the admission in evidence of exhibits 3 and 4. The tenor of the' letter claimed to be written in answer to exhibit 2 is not in evidence, and there is no way to know whether the tenor of exhibit '3 is in answer to the tenor of the letter claimed to be written in answer to exhibit 2. It clearly appears that exhibit 4 was not properly received in evidence,, there being no foundation for its reception.
With all the letters we have referred to, being concededly inadmissible in evidence, the letter, exhibit 5, claimed to be written by the plaintiff in reply to exhibit 4, cannot be supported by exhibit 4 or any other preceding letters, and, standing alone, even if it were admissible, all that could be said of it would be that it is an offer by the plaintiff to purchase the land, which was declined by the defendant, if it is-assumed that exhibit 6 is a letter signed by the defendant or under his authority, but exhibit 5 is subject to the same fatal error as exhibits 4 and 2. The testimony with reference to this letter, exhibit 5, does not show that it was deposited in the postofiice or the United States mail or any postage paid.
Testimony with reference to this letter is as follows:
Q. After receiving the letter of April 4th, did you write any letters to Daniel Keane?
A. Yes.
Q. Have you got the original letter ?
A. Yes.
Q. You haven’t got the letter you mailed to him, have you?
A. No.
Q. I will show you exhibit 5 and ask you if that is a copy of the letter you sent to Daniel Keane on April 14, 1916 ?
A. Yes.
*576Q. Did you inclose the original letter in an envelop ?
A. Yes.
Q. And addressed it to Daniel Keane at 642 Inglehart avenue, St. Paul?
A. Yes.
Q. After sending that letter did you receive any further letters from Daniel Keane?
A. Yes.
Q. I will ask you whether you received exhibit I in the mail ?
A. Yes.
Q. About the lfth or 18th of April?
A. Yes.
Q. About that time?
A. Yes.
Q. And is exhibit 6 the letter that was contained in that envelop?
A. Yes.
It is apparent that there was no foundation laid for the introduction of exhibit 5, for the reasons we have above stated. This being true, •exhibit 6, the reply, was certainly not admissible in evidence. Exhibit 8 was the check for $10 which was returned with exhibit 6.
Measured by the rule which we have set forth which governs the .admission of correspondence and letters, the plaintiff has wholly failed to bring himself within said rule. It is also plainly evident that the rule is one with which it is not difficult to comply. It is also evident that it will not be wise to extend the rule further than it is, and permit letters and writings to be introduced in such a loose manner as to •open wide the door for much evil, which might easily result from any further expansion of the rule enunciated.
The only writing offered in evidence to which there is a genuine signature of the defendant is exhibit 9, which is an affidavit verifying the answer. The plaintiff put on the stand three competent witnesses, who testified to this, in effect, that the signatures of the defendant to •exhibits 9 and 6 were the same. This testimony can avail the plaintiff nothing; for, as we have seen, exhibit 6 was inadmissible, and therefore cannot be considered as part of the testimony; and even if it *577wore admissible, exhibit 6 and 9, standing alone, would not prove any •contract between plaintiff and defendant.
We are of the opinion that all the letters and correspondence, for the reasons we have stated, should have been excluded. Being thus excluded, the plaintiff must necessarily fail in his proof of the contract alleged in the complaint. Having this view of the case, it is really unnecessary to pass upon the mental competency of the defendant to enter into the contract in question, but to entirely dispose of the case we will do so.
There is testimony on behalf of the plaintiff, that the defendant was, at the time in question, about seventy-seven years of age. During the months of March, April, and May, 1916, he was very sick, afflicted with heart trouble; he had two operations. There was testimony that he could not carry on a connected conversation, that he was ordered by the doctor not to speak, that his mind wasn’t right, that he would talk on one subject and the next time he would forget all about it. This testimony was given by his wife. We think the testimony, in this regard, standing alone and undisputed, is sufficient to establish a want of capacity to execute a contract as important as the one under consideration, however, or, in fact, to execute any contract. Especially is this true when the great age of the defendant is taken into consideration, coupled with the undisputed afflictions with which he was suffering at the time in question.' We are convinced that the mind of the •defendant was so incapacitated as to be unable to comprehend the import and consequence of business transactions of the nature of the one under consideration, and he was not in such mental and physical condition, according to the testimony, to have capacity to enter into the contract under consideration.
It appears to us, for the reasons hereinbefore stated, that the plaintiff can never recover upon his alleged contract, if for no other reason than the incapacity of the defendant. This being true, a new trial •could serve no useful purpose.
Judgment is reversed, and the District Court is instructed to enter a dismissal of the action, with costs in favor of the defendant.
