The plaintiff alleges in his petition that,he sold and delivered to Robert L. Jones in his life-, time large quantities of wood of the price and value of $6,525.35, and that after deducting all credits and payments on account thereof, there remains a balance still-due him in the sum of $2,932.25, for which he asks judgment. The answer in the case was filed before the death of Mr. Jones. In it he denies the allegations of the. petition, except as thereinafter stated by him. He pleads-as a defence that the wood, for the price of which plaintiff sues, was sold and delivered to him as guardian of Joseph H. Locke, an insane person, whose estate and body he had charge of as guardian, by virtue of appointment of the probate court; that at the time of the sale-thereof plaintiff knew that defendant was acting only in the capacity of guardian, and not otherwise; that at the time of such sale the agreement and understanding between plaintiff and defendant was that defendant was in no wise to be personally bound to pay for said wood, and that the plaintiff relied wholly upon the estate of said Locke for his pay, and never intended to hold defendant individually liable therefor. He also alleges-*583that none oí said wood was received to his úse or benefit, but that it was all received to the use and benefit of the «state he had in charge.

The issues thus raised were tried by the court without the intervention of a'jury, and judgment was rendered in favor of defendant, who is the widow and administratrix of said Robert L. Jones. The plaintiff appealed from this judgment, accepting an affirmance proforma in the St. Louis court of appeals. It is proper for me to mention in this connection that the plaintiff instituted an action in equity against the assets of the estate of said Locke in the hands of Mr. Lancaster, who had succeeded Mr. Jones as guardian, for the same wood mentioned in this case, alleging in his petition substantially the material facts pleaded specially in the defendant’s answer. In his petition he averred that the wood was sold and delivered for the use and benefit of the estate of said Locke, in the business of manufacturing lime and cement, which the guardian of said estate undertook to carry on, and did carry on after the death of said Locke, for the benefit of his wife and children, the beneficiaries of his estate. On appeal to this court it was held that the guardian had no authority as such, to subject the assets of the estate under his charge to the risks and hazards of the manufacturing business undertaken by him, and that the plaintiff, furnishing his wood with full knowledge of the guardian’s want of power to incur new obligations, acquired no lien upon the assets of the estate. Michael v. Locke et al., 80 Mo. 548. The facts under which the wood was alleged, in the previous ease, to have been sold and delivered to the estate, are ignored in the petition in this case, and the guardian is ealled upon to pay for the wood as if sold to him in his individual capacity and devoted to his private use.

In support of his case, the plaintiff urges that where a person assumes to act for or in behalf of another, with©ut authority, an action can be maintained on the contract against the person improperly acting as agent. *584From.this he concludes that Jones must have been liable to plaintiff for the value of the property delivered to him, if he had no power to bind the estate in his charge. If the bare want of authority in the agent or trustee to bind the person or estate for which he assumes to be acting, renders him individually liable, irrespective of facts and circumstances indicating that no such liability was contemplated by either party, then the plaintiff is entitled to judgment upon the facts admitted in the answer. But I am satisfied that under the best considered modern decisions the principle invoked by the plaintiff cannot be-carried to such an extent. The true rule, I think, is stated in Western Cement Co. v. Jones, 8 Mo. App. 373, to this effect “ that where all the facts are known to both parties, and the mistake is one of law as to the liability of the principal, the fact that the principal cannot beheld is no ground for charging the agent with liability.” To the same effect is Humphrey v. Jones, 71 Mo. 62. In the present case there is no pretense that the guardian made any misrepresentation ©f fact, or was guilty of any concealment relating to his authority to contract with plaintiff. The evidence indicates clearly that both parties believed in good faith that the estate of Joseph H. Locke was responsible for the wood purchased by defendant in his capacity of guardian. Acting upon -feat faith, the guardian paid the plaintiff the greater portion of his debt from the assets of the estate. The simple fact that both parties were mistaken in the law about the authority of the guardian, ought not to render the guardian liable individually, in the absence of any promise to that effect by him, and when it is apparent that no-benefit has been received by him.

The plaintiff undoubtedly could recover by establishing a lawful promise on the part of the guardian to be responsible individually, or by developing such facts and circumstances surrounding the sale and delivery of the wood as might prove that the credit according to the *585■understanding of the parties, was really given to the guardian and not to the estate in his charge. This view of the law was conceded by the court in an apt declaration applicable to the evidence before him : £ ‘ The court declares the law to be that if the plaintiff sold the wood to Robert L. Jones in his capacity as guardian of Joseph H. Locke, and did not intend to hold Robert L. Jones personally bound for the price of the wood, at the time of the sale, then plaintiff cannot recover.” In rendering judgment for defendant the court must have been satisfied that the plaintiff did not, as a matter of fact, intend to hold Robert L. Jones personally bound for the price of the wood at the time of selling- the same. There is ample evidence in the record to sustain this finding; accordingly the judgment is affirmed.
