This case comes into this court upon appeal from an order in. the court below, overruling a motion for a new trial.
The complaint is founded upon a written instrument, of which the following is a copy:
“ Virginia City, M. T., Hov. 5, 1867.
“Six months after date we, or either of us, promise to pay to Norval Harrison and Columbus Hampton, or order, two hundred and twenty-two ounces four and one-half pennyweights of clean gulch gold dust, or its value, with interest at the rate of five per cent per month until paid.
“F. D. VANDERLIP,
“W. H. THOMAS,
“JOHN McROBERTS.”
The complaint avers, that for a valuable consideration on the 16th day of March, 1868, this note or contract was trans*402ferred by Harrison & Hampton to plaintiffs, and that plaintiffs are now the owners thereof, and that on the 18th day of July, 1868, the plaintiffs entered into an agreement with said Thomas and McRoberts, whereby the rate of interest to be paid on said instrument was to be computed at the rate of five per cent per month from the 16th day of March, 1868, to the 18th day of July, 1868, and at the rate of three per cent per month from the 18th day of July, 1868, until the same should be paid. That no part of the principal or interest has been paid, and that the same is now due to plaintiffs.
The defendant Yanderlip does not answer. The separate answer of 'defendants, McRoberts and Thomas, admits the execution and delivery of the note or contract described in complaint, the assignment thereof to plaintiffs on the 16th day of March, 1868, and the agreement as to the rates of interest as specified in said complaint. But said defendants, defending against the cause of action set forth in the complaint, aver, that on the 18th day of July, 1868, at Virginia City, Montana Territory, said plaintiffs, under the firm name and style of P. A. Largey (that being one of the firm names of said company), entered into an agreement with said defendants, Thomas and McRoberts, for a valuable consideration, whereby it was promised and agreed, in consideration of the covenants and promises in said contract contained, to berdone and performed by said defendants, the said plaintiffs did then and there and thereby release these defendants from.any and all liability on the note or contract in the complaint set forth and described.
The agreement whereby these defendants claim to be released and discharged from the obligations of the note or contract upon which this suit is instituted, and from all liability thereon, is in the words and figures following, to wit:
“Agreement.”

*407To the introduction of this agreement in evidence by the defendants, the plaintiffs objected, upon the ground that it is no defense to the contract for gold dust; that it does not support the averments of the answer, and that, if plaintiffs are liable thereon, their proper remedy is a suit upon the agreement. These objections to the agreement were overruled, and the agreement received in evidence. This action of the court is assigned for error, and the main question presented by this record is, as to the admissibility of the foregoing agreement in evidence, under the pleadings in this case.
The defendants aver, in their answer, that the agreement of July 18, 1868, released them from all liability upon the contract for gold dust, and that they are wholly discharged from the obligations of the same. It is claimed by defendants that this agreement is a merger of the gold dust contract, that it was designed to, and that it does, take the place of said contract, and that, by reason of this agreement, a right of action upon the contract or note in complaint described has ceased.
It thus becomes necessary to ascertain, by careful analysis and interpretation, the true intent and meaning of the agreement of July 18, 1868.
At the time this agreement was made, the contract for gold dust (or note, as I will hereafter call it for convenience) had become due, and a suit in attachment had been commenced against defendants, including defendant Yanderlip, and this situation of the parties we have the right to consider, to enable us to properly interpret their acts. The plaintiffs were demanding their pay upon the note then due and unpaid; the defendants could not meet this obligation, and this agreement was the result of this situation. Was it the intention of the parties thereto, and did they in terms merge the note in the agreement, and thereby abandon and lose their rights and interests in the note ? The answer to this question will decide the case.
*408The stipulations of the agreement:
(1.) Caused the suit in attachment to be dismissed and settled.
(2.) It changed the rate of interest on the note from five per cent to three per cent per month.
(3.) It extended the payment of the note for one year, from July 18, 1868.
(4.) It stipulated to deliver ditch and mining property therein described to defendants Thomas and McHoberts, and from the proceeds thereof to pay first a n'ote held and owned by plaintiffs against Yanderlip and one James McEvily, for two hundred and twenty-two ounces and four and one-half pennyweights of gold dust; and, second, to pay the note in the complaint described; and, third, to remain in possession of said property, and to work the same until they should fully re-imburse themselves, and pay back to themselves all the moneys or gold dust that they should so pay on said notes.
(5.) If, from any cause, defendants are hindered or prevented, by rent or sale of ditch and mining property, from paying notes, then the plaintiffs bind themselves to rebate all interest on note in complaint described, and the payments that have been made to be applied upon the principal of said note.
(6.) To further secure the payment of said note, the defendants agree to cause one George W. Allen to execute and deliver to plaintiffs a mortgage of one undivided one-fourth interest in the Highland and Pine Grove Pluming Company of Madison County, M. T.
It will be observed that the note, as a distinctive separate obligation, is nowhere lost sight of in this agreement. The rate of interest is changed from five to three per cent per month, but the note is still to bear interest and to be in full force and operation for that and all other purposes. The time of the payment is delayed for one year, but at the end of the year the amount due thereon could have been demanded; and can it be doubted that a suit thereon could have been instituted and payment enforced, notwithstanding this agreement ?
*409The full force and effect of this agreement was, to extend the time for the payment of the note, and to reduce the rate of interest thereon, and it operates simply as collateral security to the note. The note was due. The plaintiff promised to delay payment, but, in consideration of such promise, he was to receive a mortgage against Allen, and the note against Yanderlip and McEvily was to be paid.
The agreement operates to place in the hands of the defendants the means whereby to pay the note, and every purpose and intent thereof was to create security for the payment of the note, and if there has been a failure to perform this agreement by the plaintiffs, on their part, an action could be maintained against them thereon, but whether the agreement itself fixes the measure of damages, and whether it could be set up as an equitable defense to this note, it is not now necessary to determine.
The agreement operates to delay the payment of the note, and where the promisee of a note, payable at a day certain, contracts at the time the note is given or after it has become due, not to demand payment of it until a certain time after its maturity, such contract is a collateral promise for the breach of which, if there be a legal consideration, an action may lie, but it will not bar an action on the note when due by the terms of it. 4 Mass. 414. An agreement, to operate as a merger of a note, must be such a one as by its terms or by its legal intent and meaning would defeat a right of action on the note.
This agreement was offered and received in evidence to support the allegation of the answer, that the agreement released defendants from all liability on the note. We are of opinion that the agreement does not operate to that extent, and that it does not support the allegatiou of the answer; and, upon the principle that the evidence offered must correspond with the allegations, and be confined to the point in issue, the agreement was improperly received in evidence under the pleadings in the case.
It may be proper to remark, that although the damages that may have resulted to the defendants, by a breach of *410tMs contract on the part of the plaintiffs, may have been set np as an offset to the note (a question we do not think necessary to decide), yet, there are no allegations of damages, for the breach of said contract in the answer, which would entitle the defendants to prove the same.
The order overruling the motion for a new trial is set aside, judgment reversed, and cause remanded for further proceedings.
Exceptions sustained.
