delivered the opinion of the court.
The People’s Bank of' Rural Retreat, hereinafter called plaintiff bank, is here complaining of three orders of the Circuit Court of Washington county: One, an order of September 17, 1926, holding that the People’s National Bank of Abington, hereinafter called defendant bank, or Abingdon Bank, had been misjoined with the Abingdon Warehouse Corporation and requiring the Rural Retreat Bank to elect whether it would prosecute its action against the warehouse corporation or the Abingdon Bank, and upon election being made to prosecute the action against the Abingdon Bank, dismissing it as to the warehouse corporation. (This order permitted the plaintiff to amend its notice by alleging that the warehouse corporation was insolvent.) Two, an order of October 12, 1926, sustaining the demurrer to the plaintiff’s notice of motion for judgment upon the first ground (hereinafter set out), and allowing plaintiff to amend its notice. Three, an order of December 10, 1926, dismissing plaintiff’s action upon the plaintiff’s declining to amend.
The notice of motion which fully but concisely states the facts' upon which the plaintiff relies for recovery against the defendant is copied in the margin.*
*654There were several grounds of demurrer presented to the trial court, but if the trial court was right in sustaining the demurrer upon the first ground, which was that the letter of November 12, 1919, copied in the notice of motion, did not constitute a guaranty of the note of April 2, 1926, as we think it was, it is unnecessary to consider any other grounds of demurrer.
The case then presents on]y two questions for decision.
(1) Did the court err in holding that the defendant bank and the warehouse corporation were misjoined as parties defendant?
(2) Did the letter of November 12, 1919, constitute a guaranty of payment, by the defendant bank, of the note of April 2, 1926?
1. It is obvious that, even if there were not a misjoinder, the error, if any, was harmless, as the ware*655bouse corporation was alleged by the plaintiff to be insolvent. In addition the defendant bank derived no benefit from the court’s holding. The court’s action was brought about by the motion of the Abingdon Bank to dismiss it because of misjoinder of parties. The court held that there was a misjoinder but refused to dismiss the defendant bank, and required the plaintiff to elect as to which defendant it would prosecute the action against, which it did. The defendant bank failed in its motion, which was to obtain its own dismissal.
2. Examination of the notice of motion dis*656closes that if there is a legal obligation upon the defendant to pay the note in question here, it arises alone from the letter of November 12, 1919, which is claimed to be a guaranty as to all notes placed with the plaintiff bank from customers of the defendant bank outstanding at the date of the letter and a continuing guaranty of such notes bearing date subsequent to the letter. This is true because it is not alleged that the defendant is a party to the note or that it endorsed it.
It is true it is contended that the second count of the notice is a common count for money had and received by the defendant bank, and that, independently of the first or special count, it is entitled to recover on the common count, but it is specifically alleged in the so-called common count that the sum of $3,200.00 is due “by reason of the matters in this notice set out,” and the “matters in the notice set out” relate entirely to the alleged guaranty contained in the letter. The only cause of action alleged against the defendant in the notice of motion, therefore, is upon the letter of November 12, 1919. ít follows that if a good cause of action wras not stated upon that letter, the demurrer was properly sustained.
On behalf of the plaintiff bank it is contended that the letter in question not only is a guaranty for the payment of the notes referred to then in the possession of the plaintiff bank, but that it was a continuing guarantee for such notes as should, in the future, be acquired from the defendant bank.
It is not insisted with any degree of force, if at all, that a literal reading of the letter included in its operation the note sued on, but it is insistently urged that as the notice alleges that it was. the intention of the parties that the letter should be a continuing agreement and should protect future as well as past discounts, and *657as the notiee goes further and. alleges that the parties by a course of dealing over a period of years practically construed the letter as a continuing guaranty, that the defendant bank is bound by the construction and that the court erred in sustaining the demurrer.
The rule as to the “doctrine of practical construction”—that is, the construction put upon an instrument by the parties thereto—is well settled in Virginia. It has been frequently applied in this State, but an essential to its application is, that the instrument to be construed must be ambiguous. If it is not ambiguous in its terms it must be construed without the aid of the views of the parties as to it or of their conduct under it. Knick v. Knick, 75 Va. 12, 19; Trigg v. Bucyrus Co., 104 Va. 79, 51 S. E. 174; Butter Bros. v. Virginia Railway Co., 113 Va. 28, 73 S. E. 441; Northrop v. Richmond, 105 Va. 355, 53 S. E. 962; Chesapeake and Potomac Tel. Co. v. Wythe Telephone Co., 142 Va. 529, 129 S. E. 389.
It follows that it is necessary to construe the letter and ascertain whether its meaning is plain upon its face or whether it is not plain upon its face. If it is plain upon its face, parol evidence as to practical construction of the parties would be inadmissible upon the trial, and the allegation of practical construction contained in the notiee is mere surplusage.
The plaintiff bank asks the court to construe the letter of November 12, 1919, as a continuing gauranty extending from its date for an indefinite time into the future with no limitation as to amount of liability that might be incurred under it—to construe a letter dated November 12, 1919, as guaranteeing payment of a note dated April 2, 1926.
That the language of this letter negatives any intention on the part of the defendant bank to assume any legal obligation as to this note or any notes which *658it might place with the plaintiff bank in the future is clearly shown by the analysis of the letter contained in the brief of defendant in error. In that analysis this appears: “The letter consists of two sentences, the first of which refers to notes ‘that have been placed with you from our customers.’ This sentence necessarily refers only to notes held by the plaintiff bank on November 12, 1919. As to such notes, the undertaking of the defendant bank is specific: ‘any time you wish any of these notes paid, just advise us and we will take same up at this bank.’ The second sentence of the letter deals with the future only, and as to notes that may be placed with the plaintiff in the future, the language is very different from that referring to the notes previously placed. As to such future notes, the letter states: ‘We will send you no notes that we would not handle here, and none but those that our Finance Committee pass on favorably.’ It is immediately obvious how different is the undertaking as to such future notes. There is nothing said about paying them upon request, or about paying them under any circumstances whatever. The second sentence constitutes perhaps a recommendation of such future notes, but the court will look in vain for anything in it in the nature of a guaranty or warranty of any kind. If it had been the intention of the letter to make the same engagement as to future notes that it made as to past notes, it would have been very easy to have said so. The failure to say so, combined with the use of language clearly indicating an entirely different position with respect to future notes, should be reasonably construed as evincing an intention to undertake no advance liability as to such future notes. In such a situation, the language of the letter, in combination with the failure of the defendant bank to endorse the note of *659April 2, 1926, constituted the defendant hank a mere forwarder or ‘placer’ of the note. The plaintiff bank, having taken the note without any assumption of legal liability thereon by the defendant bank, can hold only the parties to the note itself. The complete change of the language of the letter when it came to deal with future notes plainly evidences a corresponding complete change of intention with regard to such future notes.
“A plausible reason suggests itself for the unwillingness of the defendant bank to undertake any legal liability as to such future notes, in that it did not know, and could not know, what notes it might place with the plaintiff bank in the future or who the parties thereto might be. Hence, it was naturally unwilling to undertake a blanket and indefinite liability of that kind. It was willing to say that it would not send any notes except what it believed to be good, but it was unwilling to go any further than that.”
The rule of construction of guaranties is well stated in 12 R. C. L. 1074, section 25, thus: “There is considerable diversity of opinion as to the strictness or liberality with which guaranties shall be construed. On the one hand, the rule is applied, that if there is any ambiguity in a written instrument it is construed against the person using the language, which requires a guaranty to be construed most strongly against the guarantor. On the other hand, in some jurisdictions, a guarantor is said to be a favorite of the law and the guaranty is construed strictly in his favor. Between these contrary opinions is the middle ground, that there shall be neither a strict nor a liberal construction of a guaranty, but that it shall receive a reasonable construction and be fairly construed according to the intent of the parties in the same manner as other contracts are *660construed. This doctrine requires a construction which neither enlarges the words of the guaranty beyond their natural import in favor of the creditor, nor restricts them in aid of the guarantor. The guaranty should be construed so as to give effect to the intention of the parties thereto and so as to carry out rather than to defeat the purpose for which it was executed. In arriving at this intention, generally little aid may be had from decisions on other contracts of guaranty, and the particular contract in question must be given effect according to its own expressed intention, as gathered from all the words and clauses used, taken as a whole, due regard being had also to the surrounding circumstances, especially where the expressed terms of the contract are ambiguous. But by whatever rule' the meaning of the contract is determined, after the meaning is found the effect of the guaranty is strictly construed in favor of the guarantor. His liability cannot be enlarged beyond the strict intent of the instrument." (Italics supplied.)
Prom the foregoing it is clear that there is no ambiguity in the letter which would permit the introduction of evidence of practical construction that the letter was not a guaranty as to future notes, and that there was no error in the action of the court in sustaining the demurrer upon the ground that the letter of November, 1919, did not constitute a guaranty of the note of April 2, 1926, and that the order of December 10, 1926, complained of, should be affirmed.
