prepared the opinion for the court.
Defendants bad judgment below. Plaintiff moved for a new trial, wbieb was denied. From the judgment and order denying his motion for a new trial, he has appealed.
It is stated in the amended complaint, in substance, that plaintiff is the owner and entitled to- the possession of certain frame building’s of the value of $¡800, situated on land belonging to the Northern Pacific Railway Company, in Deer Lodge county, and in which land neither jdaintiff nor defendant have any interest; that the buildings are not affixed or permanently attached to the land, and can be removéd without injury; that the defendants unlawfully and wrongfully withhold and detain the possession of the said buildings from the plaintiff; that *487prior to tbe commencement of -the action tbe plaintiff demanded of tbe defendants, tbe possession of tbe same, but tbe defendants refused, and still refuse, to deliver them to plaintiff.
In tbeir answer defendants deny that plaintiff is tbe owner or entitled to tbe possession of tbe buildings, and deny that the defendants, or either of them, unlawfully or wrongfully withhold or detain tbe possession of said property or any part thereof; deny that tbe buildings can be removed from said land without injury. And defendants, for further and separate answer to tbe complaint of plaintiff, allege “that they are now and were at all times mentioned in plaintiff’s complaint and for a long time prior thereto the owners of and in possession of tbe property and every part therfeof mentioned in plaintiff’s complaint.”
Tbe case was tried to a jury. Plaintiff introduced evidence showing that tbe defendants and one James McGovern, who were partners doing business under tbe firm name of M. E. Kelly & Co., on April 26, 1900, executed a bill of sale to one Lulu E. Largey. Tbe consideration named in tbe bill of sale is $15,000 and tbe cancellation of all indebtedness due and owing to Lulu E. Largey from the vendors. Tbe property conveyed is described as follows: “One store building and dwelling bouse attached (new); one warehouse (new) ; one barn (new); and all fixtures and attachments thereunto belonging. All of said buildings being situated at Gold Creek station, Deer Lodge county, Montana. Also all goods, wares and merchandise now in and around said buildings (except tbe household furniture in said dwelling bouse attached to said store building), belonging to the said first parties, consisting of a stock of general merchandise, including all counters, scales, cash register, stove, safe, all other goods and property used in and around said store and useful in connection with said business. This bill of sale is intended to cover all goods, wares and merchandise of every kind, character and description belonging to said above named first parties, belonging to> and connected with tbe general store and mercantile business of tbe firm of M. E. Kelly & Co.”
*488On December 7, 1900, Lulu F'. Largey conveyed said buildings to the plaintiff, wbo demanded possession of tbem from tbe defendants, which was refused.
The defendants sought to defeat plaintiff’s action by showing that the contracting parties did not intend to include the buildings in the bill of sale. The evidence discloses that one Bernard Noon was Mrs. Largey’s business agent, and acted for her in the transaction which culminated in the bill of sale being executed to her. The court permitted defendant T. L. Kelly to recount conversations ,and understandings had between himself and Noon prior to* the signing of the bill of sale, and thereafter concerning what property was intended to be included therein.
It will be observed that the defendants did not plead any mistake or imperfection in the writing; neither was the validity of the bill of sale in dispute; nor was* there* any attempt to explain an extrinsic ambiguity, nor any attempt to establish illegality or fraud. There Avas no question concerning the construction of the instrument. Under the pleadings* in this case, such proof was inadmissible. (Sections 3132, 3136, Code of Civil Procedure, and Section 4430, Civil Code; Gaffney Mer. Co. v. Hopkins, 21 Mont. 13, 52 Pac. 561; Sanford v. Gates, Townsend & Co., 21 Mont. 277, 53 Pac. 749; York v. Steward, 21 Mont. 515, 55 Pac. 29, 43 L. R. A. 125; Ming v. Pratt, 22 Mont. 262, 56 Pac. 279; Armington v. Stelle, 27 Mont. 13, 69 Pac. 115, 94 Am. St. Rep. 811; Riddell v. Peck-Williamson H. & V. Co., 27 Mont. 44, 69 Pac. 241.)
Over plaintiff’s, objection defendants Avere permitted to introduce in evidence two letters and a so-called certificate written by Noon to T. L. Kelly several months after the bill of sale was executed and delivered, and before the* property was sold to plaintiff. The letters and certificate were to the effect that Noon did not claim the buildings for Mrs. Largey; that she was not the owner of them, and did not claim any interest, right or title in them; that"the buildings w:ere not included in the bill of sale, but Avere expressly reserved therefrom. The *489bill of sale was thus directly contradicted. In explanation of these letters and the certificate Noon testified that he had put the bill of sale 'away for safe keeping and had forg’otten its contents ; was misled by Kelly as to what was included in it. Both Mrs. Largey and Noon testified that the latter had no authority to sell or dispose of the buildings in toy way, and this testimony was uncontradicted.
To bind the principal, the declarations of an agent must be made within the scope of his authority, at the time of the transaction, and be a part of the res gestae. If made after the transaction is completed, they are in the nature of hearsay, and are mere narrations of a past transaction. (Moore v. Bettis, 11 Humph. 67, 53 Am. Dec. 771, and note; Garfield v. Knight’s F. & T. M. W. Co., 14 Cal. 36; Clunie v. Sacramento Lumber Co., 67 Cal. 313, 7 Pac. 708; Beasley v. San Jose Fruit-Packing Co., 92 Cal. 388, 28 Pac. 485; Birch v. Hale, 99 Cal. 299, 33 Pac. 1088; Luby al Hudson River Railroad Co., 17 N. Y. 131; Herbert v. King, 1 Mont. 475; Mechem on Agency, Sec. 714.)
It is apparent that the letters and certificate were nothing more than mere declarations made by the agent several months after the transaction to which they related occurred, and their reception in evidence was error.
Over plaintiff’s objection the court also permitted the defendants to- introduce in evidence an acrimonious letter written by Noon to T. L. Kelly on December 3, 1900. Under the rules above announced, it was inadmissible for any .purpose as being the mere declaration of an agent; but, in addition to that-, it was objectionable because it did not even remotely refer to any matter in controversy, so far as can be ascertained from its terms. Besides being wholly irrelevant and incompetent for any purpose, it- probably tended to prejudice the jury to plaintiff’s injury under the testimony already in evidence.
What we have said renders a discussion of the instructions unnecessary.
*490No question bas been raised by counsel as to1 whether the buildings in suit are real or personal property.
For the foregoing reasons;, we are of the opinion that the judgment and order should be reversed, and the case remanded for a new trial.
