The admission of the receipts given by Gerould, however incompetent as evidence against the plaintiff, would furnish no reason for disturbing the verdict, because they did not prove and had no tendency to prove any fact in controversy, or anything which could possibly have occasioned any prejudice to the plaintiff’s case. They were merely written recitals of facts precisely according with the plaintiff’s own testimony. He testilled that, by the contract between Tobev and himself. Tobey *58was to pay the interest on his note, and that the payments were made and allowed to him in a suit on the note; which was all that the receipts imported.
The evidence of the sale of hides and vegetables from the farm by Tobey would certainly have been incompetent, if it stood alone, and were objected to ; because it had nothing to do with the question at issue. Both parties admitted that Tobey was in the rightful occupation of the farm, with authority to use or dispose of its annual products ; and the sale of such articles by him would have no bearing upon the question of his power to sell the wood and timber. But the objection seems to have been taken to the whole testimony offered of sales to other persons than the defendants of vegetables, hides and small quantities of wood and timber, without distinguishing between the articles; and there is nothing in the exceptions to show; that they were not all sold together to each person. If the testimony as to the wood and timber were therefore competent, and admitted under proper instructions, we should not be satisfied that the plaintiff was entitled to an exception because the witnesses had also spoken of the hides and vegetables.
But we are of opinion that the instructions given to the jury were not strictly accurate, as applied to the state of facts set forth in the bill of exceptions; and that, taken in connection with the refusal to give the whole or any part of the instructions asked by the plaintiff, or to limit in any way the effect of the evidence of the sales of wood and timber to other persons, they were likely to mislead the jury. The exceptions are therefore sustained; and the reasons for this conclusion will be best presented by a brief analysis of the whole case.
Two things are perfectly clear at the outset: First, that the plaintiff was the owner of the farm, and with it of the wood and timber which were sold to the defendants, so that the defendants must show that the property had passed to them from him. And secondly, that they were bound to ascertain their \ endor’s title, and their liability would not be discharged merely because they had bought and paid for the property in good faith.
*59The defendants relied on a purchase from Tobey, the tenant on the plaintiff’s farm, and payment to him. The first question, then, was of his authority to sell the wood and timber. Tobey testified that by his paroi contract with the plaintiff he was to occupy the farm, with the right to purchase by paying $5000 and interest; and to have the right to cut and sell wood and timber from the farm at his discretion to pay the purchase money. There was evidence that the plaintiff knew of the first sales to the defendants, and forbade Tobey to sell any more. The court instructed the jury that if the contract were such as Tobey stated, the plaintiff could not maintain the action., The plaintiff asked for the instruction, that if the plaintiff forbade Tobey to sell any more, the' defendants would have no defence to his claim for what was subsequently sold, although he gave no notice to the defendants that he had forbidden Tobey to sell more. This instruction the judge refused to give. The plaintiff now contends that if Tobey had the right to sell under the verbal contract, yet that the authority given him was revocable, the contract not being a binding one under the statute of frauds, and so was terminated by the revocation. Admitting this to be true, so far as Tobey was concerned, it might not necessarily follow that the rights of the defendants would be concluded. The ruling of the court would be too broad, because it contained no exception of the case of a revocation of Tobey’s authority. On the other hand, the ruling asked by the plaintiff would be open to question; because, if an agent has been employed with full authority to dispose of property, a private revocation of that authority by his principal will not affect persons who have previously dealt with him on the faith of it, and who have no notice of the revocation.
The defendants further introduced evidence that between the years 1855 and 1860, which was the time during which the sales of wood were made by Tobey to the defendants, several other persons in the town where the farm was situated bought small quantities of wood and timber of Tobey. This evidence was objected to by the plaintiff; and he also asked that the jury should be instructed that it would not avail the defendants, *60unless the jury were satisfied that both Bragg and the defendants had notice of such sales, and that Tobey was claiming to make the sales as owner of the property or as the authorized agent of the plaintiff, nor unless they further believed that the plaintiff, by his silence or omission to notify the defendants that Tobey had no right to sell, acted in bad faith or collusively with Tobey. This instruction was refused. There was some evidence that the plaintiff was several times in the town where the sales were made during those years.
The evidence offered was as we think admissible, with some of the qualifications asked. The fact of frequent sales by one person of the property of another, without objection on his part, if known to the owner of the property, would be evidence tending to show that the sales were made by his permission. And without other direct proof that they were known to him, the frequency and amount of the sales themselves might furnish such evidence of general notoriety, that a jury would be authorized to infer his knowledge of them, if his opportunity of knowing was shown to be ample. But if the jury were not satisfied that they were known to him, they would prove nothing; and the jury should have been so directed. Their weight as evidence of an actual authority to Tobey to sell would not of course be affected by their being known or not known by the defendants. The question of actual authority in Tobey to make the sales to the defendants is an entirely different one from that which was coupled with it in the plaintiff’s prayer for instructions, namely, an estoppel in pais by reason of bad faith m the plaintiff. The evidence of sales to other persons than the defendants could have had no bearing upon the latter, without proof that the defendants knew of those sales, and were induced to purchase themselves in consequence of that knowledge.
And it is upon this ground of estoppel, upon which the case rnaj have turned, and which certainly assumed great prominence at the trial, that we think the instructions given to the jury require careful consideration. They proceed upon the assumption that the plaintiff’s version of the contract was correct, and that Tobey had no actual authority to sell the wood and timber *61to the defendants. Upon this assumption, the jury were told that the defendants “ could not defend against the action, if there was no waiver of his rights by Bragg.” This use of the word “ waiver ” is hardly technical, as there is nothing in the transaction to which a “ waiver ” could strictly apply. But the court proceeded to state what was meant with more exactness, and instructed the jury “ that if the owner of property, knowing that one who is not the owner is selling the property to a purchaser who supposes he has a right to sell it, sits by and sees it sold, and sees the purchaser pay for it, without disclosing his ownership, he cannot thereafter maintain his claim for its value. And if the jury are satisfied from the whole evidence that the plaintiff, during the time when Tobey was cutting off the wood and selling it, and receiving pay for it from the corporation, knew that he was doing so, and said nothing, making no claim upon the corporation and giving them no notice, he cannot now recover.” We think these instructions cannot be supported, and that they carry the doctrine of estoppel farther than is warranted by principle or authority.
The doctrine is stated in Pickard v. Sears, 6 Ad. & El. 474, “ that where one by his words or conduct wilfully causes another to believe the existence of a certain state of things, and induces him to act on that belief, so as to alter his own previous position, the former is concluded from averring against the latter a different state of things as existing at the same time.” And in Freeman v. Cooke, 2 Exch. 664, it is said that “ in most cases to which the doctrine in Pickard v. Sears is to be applied, the representation is such as to amount to the contract or license of the party making it.” And see Audenried v. Betteley, 5 Allen, 382, and cases there cited. And we do not doubt that there are cases where the mere silence of a party may amount to a representation, and may be justly held to constitute a ratification of acts done in his presence, or with his knowledge, under circumstances which call for his action if he disapproved them. In this view, the first sentence of the instructions we are considering may be a correct statement of the law. If a party “ sits by,” and “ sees ” his property sold and paid for, his silence may be *62presumed to give consent. But we are aware of no case in which it has been held, nor do we know of any just reason why it should be held, that, where there is no fraudulent act or contrivance, no express fraud meditated or promoted, a party whose property has been wrongfully dealt with in his absence should lose his right to an indemnity, because he has failed to notify a party to the wrong that his rights were violated. It might be very proper and kind in him to notify a trespasser who he had reason to believe was trespassing innocently, and was likely to repeat the trespass, of the nature and consequences of his mistake ; but "no rule of law requires him to do so, under the penalty of losing his property. In the last sentence of the instructions, the court omit entirely the element of any participation in the transaction, or even of presence at it. The plaintiff was not shown to have any connection with the defendants whatever; or any means of communication with them, unless by letter, or by making a special effort to find them. And it seems to us to be carrying the doctrine of estoppel much too far to hold that if the owner of property is aware that other persons are about to sell and buy it under a mistaken opinion that they have a right to do so, he shall lose his property if he fails to give them notice, although he has said and done nothing to cause or encourage the mistake. It is rather their duty to inquire of him. Gray v. Bartlett, 20 Pick. 193. Exceptions sustained.
