The questions presented to this court for solution are involved in the following note:
“Douglas, Arizona, April 9, 1913.
“Six months after date, for value received, we promise to pay to the order of Geo. F. Woodward, twenty-seven thousand one hundred and eighty-seven 50/100 dollars, at the Bank of Douglas, Douglas, Arizona, with interest thereon from date until paid, at the rate of six per cent, per annum; the said interest, if not so paid, to be added to and become a part of the principal, and bear the same rate of interest. And in case suit or action is instituted to collect this note or any portion thereof, we promise to pay, besides the costs and disbursements allowed by law, such additional sum as the court may adjudge reasonable as attorney’s fees in such suit or action.
“W. B. SLAUGHTER.
“GEO. N. SLAUGHTER.
“R. L. SLAUGHTER.
“For payment under contract of even date.”
The appellee, claiming said instrument to be a negotiable note and claiming to be the owner and holder thereof in due course, instituted this proceeding against the makers and the *486payee and indorser, Geo. F. Woodward, to collect the principal amount and interest due thereon.
The only one of the defendants that appeared and filed an answer was R. L. Slaughter, one of the makers of the note. He defended the action on the ground that the note was given in consideration of the performance of a certain executory contract entered into between the makers and the payee, Woodward. It is alleged that the contract was not performed by the payee, and hence a failure of consideration for the note. The theory of the defense being that the note was a non-negotiable instrument and therefore subject to that' defense, for the reason that there appears on the face of the note words that conditioned its payment, the words being: “For payment under contract of even date.” The plea of failure of consideration was stricken upon the motion of appellee, the trial court holding that the note was negotiable.
It was also alleged in the answer that the appellee took the note with full notice and knowledge of the purpose for which the same was given and the consideration thereof, and of all the circumstances under which said note was made. Evidence, upon this issue made by the answer, was introduced at the trial, the appellant on his part offering, among other evidence, the contract pleaded in his answer and out of which transaction the note sued upon originated. The contract involved the purchase from Woodward by appellant and his co-makers of a ranch and cattle situated in Mexico for a consideration of $108,750, to be paid as follows, to wit:
“The sum of $27,187.50 cash, in hand paid, the receipt whereof is hereby acknowledged by the party of the first part and the further sum of $27,187.50 three months from date hereof. And the further sum of $27,187.50 six months from the date hereof, and the further sum of $27,187.50 nine months from date hereof. Each of the deferred payments being evidenced by a promissory note of even date herewith, due three months, six months and nine months from the date hereof, bearing interest at the rate of 6 per cent, per annum from date until paid. Said notes to be payable at the Bank of Douglas, in the city of Douglas, county of Cochise, state of Arizona.”
The judgment being in favor of the appellee, the appellant, R. L. Slaughter, prosecutes his appeal therefrom and assigns *487ten. specifications of error. We think, however, that there is but one question involved — that is, the negotiability or non-negotiability of the instrument sued upon. If it is a commercial paper under the law-merchant or under the negotiaable instrument law of this state, the judgment of the lower court must be upheld.
One of the requisites to a negotiable instrument is that “it must contain an unconditional promise or order to pay a sum certain in money.” Civil Code 1913, par. 4146. The appellant earnestly contends that the words, “for payment under contract of even date” indorsed upon the note qualifies and conditions the promise to pay and makes the obligation to pay contingent upon the terms of the contract therein referred to. No case has been cited by counsel, nor have we been able to discover any, after a very thorough search, in which language such as is here involved was passed upon or discussed, although the books are full of eases based upon “conditional paper, distinctly conditional in form.” Many of such eases are cited in 7 Cyc. 575, note 82. Also note to Klots Throwing Co. v. Manufacturers’ Commercial Co., 179 Fed. 813, 30 L. R. A. (N. S.) 40, 103 C. C. A. 305.
It seems to us that the expression “for payment under contract of even date” is far from being “distinctly conditional.” Giving it the implication of a condition, it is at best conjectural and misty. The instrument is signed by the maker, in which he promises to pay a sum certain in money at a fixed time and payable to the order of a named person; and the promise to pay is certainly unconditional, unless the words in question shall be construed to qualify and make conditional the promise. Under the Negotiable Instrument Act, paragraph 4148, there may be inserted in a promissory note, without destroying its negotiability or qualifying the promise to pay: “. . . (2) A statement of the transaction which gives rise to the instrument. ’ ’
A promissory note, therefore, is not divested of its negotiable character if in addition to its ordinary provisions there is inserted a reference to the transaction out of which it arose, or a recital of the consideration for which it was given. The usual way to condition or to make contingent a promise to pay is to use language clearly carrying that intention and purpose either by direct expression or by reference to some *488extrinsic contract in such manner as to make the payment of the note subject to the terms and conditions of the contract. In 3 R. C. L. 883, section 69, the idea we have in mind is very well expressed in this language:
"It may be stated as the general rule that wherever a bill of exchange or promissory note contains a reference to some extrinsic contract in such a way as to make it subject to the terms of that contract, as distinguished from a reference importing merely that the extrinsic agreement was the origin of the transaction, or constitutes the consideration of thé bill or note, the negotiability of the paper is destroyed.”
If it can be said that the expression "for payment under contract of even date” fairly or reasonably means that the note was given and its payment was to be made "subject to the terms of the contract,” therein referred to, it would follow that, if the contract was executory, the payment of the note was subject to its conditions. There is nothing in the language to indicate that the contract referred to was an unexecuted contract. Prom what appears in the expression the contract may have been fully performed and executed. It has neither subject nor predicate; it does not assert or affirm anything — it is a mere combination of words from which it may be inferred that a contract had been .entered into between somebody on its date. We cannot enter into the speculation of inserting or supplying omitted words, as appellant would have us do, in order to give it the force and effect of limiting and qualifying the unconditional promise of the makers as contained in the body of the note — we must accept the words actually used, which do not declare anything, or assert anything, or affirm anything, but are a mere allusion to or sign-post of the transaction out of which the note originated. It does not mean the same, as suggested by appellant, as the expression, "this note is made subject to contract of even date,” for in the latter expression there is carried the idea of a subsisting and unfulfilled contract, ad executory contract.
In Klots Throwing Co. v. Manufacturers’ Commercial Co., supra, a note containing this language, "Value received, subject to terms of contract between maker and payee of October 25, 1905,” was held to be non-negotiable, the court stating that in its opinion "the special stipulation in the present note *489limits and qualifies the obligation to pay so that it is not absolute,” and with that conclusion we agree. It further said:
“Manifestly, if the provision ‘subject to terms of contract, between maker and payee constitutes merely a reference to the agreement or a statement of the consideration for the note, it does not impair the negotiability of the latter. So, if it merely constitutes notice of the existence of the contract, and not of the breach thereof, it would not affect negotiability. ’ ’
In that case reference to the “extrinsic agreement” was certain and unerring, and contained words qualifying the promise to pay. In the case at bar there is an absence of language to indicate that this note was to be burdened with the conditions of any agreement. At most it is a mere reference to the origin of the transaction and “constitutes notice of the existence of the contract,” but “not of the breach thereof.” ¥e are of the opinion that the expression indorsed on the margin of the note was intended as a mere statement of or reference to the transaction for the purpose of identification, and that it did not, therefore, affect the negotiability of the note sued upon.
We are further confirmed in this view by reference to the contract. That instrument provides that the consideration for the property to be transferred to the makers of the note was to be paid in part cash and in part by promissory notes of even date, due three months, six months and nine months from date. Here is the promise of the makers of this note that it shall be a negotiable note, for all promissory notes are negotiable. Indeed, the appellant in his answer describes the instrument sued upon as “said promissory note.” As was said by Lord Campbell, C. J., in Jury v. Barker, El. Bl. & El. 459, where the promise to pay in the note was “as per memorandum of agreement”:
“The note here is an absolute and unconditional promise as to the payer, the payee, the amount, and the date. If the addition of the words in question make the promise conditional, it is on the defendant to show that, and he has not done so.”
In the present case, the appellant not only failed to show that the promise was conditional, but actually showed that it was unconditional and unqualified, both by the contract re*490ferred to and in his answer. It further appears' from the evidence that the appellee purchased the note, paying full value, within a very few days after its execution and long’ before any claimed breach of the executory contract attempted to be interposed in appellant’s answer.
Judgment affirmed.
