The plaintiff sued in ejectment in the usual form, averring entry and ouster on the 13th of February, 1878. On the 17th of June, 1879, this suit still pending, the defendants surrendered, and the plaintiff accepted possession of the premises sued for, thus leaving to be settled by trial the abstract right of plaintiff to recover as of the 13th of February, 1878, and the damages consequent upon the adverse possession of defendants at and after the date aforesaid.
It seems that plaintiff was originally owner of the premises and on the 10th of March, 1871, sold them to the firm of Blair Brothers, consisting of J. A. Blair, R. H. Blair and J. C. Blair. At the same date said Blair Brothers delivered to plaintiff a deed of trust on the premises to secure a part of the unpaid purchase money evidenced by three promissory notes falling due at different times, and aggregating in amount about $5,500. Blair Brothers entered into possession of the premises so purchased by them, planting and growing thereon a large nursery, and carrying on a general nursery business in their firm name. On the 4th of February, 1875, Blair Bros, executed a second deed of trust covering the said premises, and including their nursery stock, for the purpose of securing to one A. L. Mason a debt of about $4000, On the 9th of February, 1877, the demanded premises and nursery were sold at trustee’s sale under the second deed of trust. The defendants, composing a firm under the name of Wallace & Co., purchased the same, and entered into possession thereof, upon surrender of Blair Bros., at the date of their said purchase. *88Alter their entry, defendants continued the nursery business left by Blair Bros., and were thus engaged when the premises were advertised and sold under the first deed of trust on the 13th of February, 1878. At this sale the plaintiff, who held the notes secured in the deed, became purchaser. As owner of the legal title, his suit should prevail, unless the defendants have pleaded and-proved a good defense against the right of possession which his title implies.
In their answer they allege that before their purchase under the second deed of trust, the plaintiff, as holder of the debt controlling the first deed of trust, agreed with them that if they would purchase the land and stock at the sale under the second deed of trust, they should have possession of the land until they could in the ordinary course of business sell off the nursery stock, and that he would not enforce his deed of trust nor attempt to take possession of the premises; that in consideration of said undertaking of plaintiff the defendants agreed to pay the interest on the secured notes of the first deed of trust during the time of their possession while disposing of the nursery stock in the ordinary .course of business; that said interest was to be paid out of the first net returns received from the nursery sales, after payment of the debt due Mason for their purchase; that they entered into possession and conducted the nursery business on the faith of said agreement, planting other valuable trees,and in pursuance thereof, paid to plaintiff orto his use $200 in April, 1877, $150 and $482 in June, 1877, and $400 in the fall of 1877. Another contract looking to a lease of the premises to defendants is pleaded, but as the evidence failed to show that it was consummated, it need not be considered further. It is alleged that plaintiff by reason of the premises was estopped from foreclosing his deed of trust and claiming possession as asserted in his petition.
No reply was filed, but the case was tried upon a denial of the defense pleaded in the answer.
*89A jury being waived, the plaintiff submitted evidence on the issue thus raised, and the defendants did likewise, against the objection of plaintiff. After the evidence was closed and instructions announced, the plaintiff took a non-suit. He now appeals from the action of the court in refusing to set it aside.
I. It is first objected and assigned as ground of error that the answer is insufficient and contains no defense to the action. This point was raised by objection to the introduction of any evidence by defendants in support of it. It will be observed that the defendants were under no legal obligation, outside of the new agreement, to pay the notes or interest thereon which were secured by the first deed of trust. They were the obligations of Blair Bros. The agreement of plaintiff to forbear enforcing his demand as a lien on the premises and to permit the defendants to go on removing and replanting trees, being supported by the promise of defendants to pay the interest on said demand is unquestionably a valid contract and binding upon all parties to it. Glasscock v. Glasscock, 66 Mo. 627. No definite period of time api^ears in the contract limiting the term of forbearance. But it is not on that account void. The law implies a reasonable time if not a total forbearance according to the circumstances and subject matter of the contract. Salisbury v. Renick, 44 Mo. 558; Glasscock v. Glasscock, 66 Mo. 627. As a conclusion of law on the face of the pleading, it could not be said that a reasonable time had elapsed at the time the deed of trust was foreclosed in the middle of the succeeding winter.
II. I do not think the court erred in refusing the declaration of law asked by plaintiff. It is laid down in the first part of it, substantially, that the court could not find for defendants, unless it found one or both agreements pleaded in the answer had been entered into between the parties and that one or both of them had been performed by defendants. This was all correct enough. But it then proceeds as follows: “And the *90court cannot find that either of said agreements alleged in said answer were or have been kept and performed, unless said agreements have been respectively and specifically alleged in all their substantive parts in said answer.” This qualification is o.ut of place in’a declaration or instruction addressed to the finder of facts. The objection to the sufficiency of the answer had been overruled. If the plaintiff desired to raise it again he should have done so by demurrer or motion to make more definite. The practice of blending it with an instruction on the facts of the case can only lead to confusion and mistake. The unobjectionable part of the instruction is sufficiently included in the instructions given at the instance of defendants to indicate that the case was tried on the theory favored by plaintiff.
III. The action of the court in giving the 4th declaration of law asked by defendants is assigned for error. It reads as follows : “ The court declares the law to be, that if defendants entered into possession of the premises in controversy, under an agreement with plaintiff, that they might carry on a nursery business on said premises, and use the stock thereon, as well as stock to be put thereon, and that he would not sell under Ms deed of trust, and that in consideration thereof they agreed to pay plaintiff certain interest on the balance due on said deed of trust, and that defendants did pay said interest, or were willing to do so, plaintiff refusing to receive the same; then plaintiff, as against defendants, did not obtain a right to possession of the premises by sale under said deed of trust, and if plaintiff did not have a right to possession at the commencement of this suit he cannot recover.” In order to understand the import and application of this declaration it will be necessary to allude to the evidence bearing upon the issue raised by the answer. The testimony of defendants tended to prove that the agreement alleged in the answer was entered into, and that the consideration to be paid by them did not extend further than the interest on the Blair *91notes, and that they had paid and were always ready and willing to pay the interest on the same according to agreement; that upon subsequent solicitations of plaintiff they had paid taxes, or rather notes outstanding for the payment of taxes, and some other outstanding obligation of plaintiff. The plaintiff, in his own testimony, admits that he had entered into an agreement to forbear-closing the deed of trust, but he does not agree with defendants as to the consideration to be paid by them. He testified that before defendants purchased under the-second deed of trust he had agreed with Blair Bros, to forbear closing them out, upon their undertaking to pay the interest on the notes amounting to about $750, the Brown, Hughes & Co. note for taxes amounting to-$480.33, and $1000 upon the principal; and that defendants, on purchasing at the Mason sale, had assumed the same undertaking. According to defendants’ testimony they never agreed to pay anything on the principal of the notes, so that the only material difference between the parties consisted of the $1000 of principal of the Blair notes. The agreement as alleged in the answer was-corroborated by a petition in a suit pending between, the parties in which the plaintiff sets out the contract substantially as alleged in the answer, omitting all mention of any claim for failure to pay said principal or any part of it. The plaintiff admits that if the agreement-entered into between them had been kept by defendants-he would not have foreclosed his security.
Yiewed in the light of this testimony, conflicting as it is, I see nothing objectionable in the instruction. If the court believed the testimony of plaintiff, there could have been no finding against him. There is nothing in the instruction to justify him in going out of court. If he-had remained in, the court might have found in his-favor, upon the evidence submitted by him. There was-nothing in the instruction to preclude such finding. It follows, therefore, that the non-suit, so far as this-instruction is concerned, was the voluntary act of plain*92tiff. As such the court could uot help him by setting it aside.
IV. The appellant objects to the second instruction given at the instance of defendants, relating to the measure of damages, which reads as follows: “2d. The court declares the law to be that if under an agreement with plaintiff, in case they should do so, defendants purchased the premises in question, and the nursery stock thereon, under a deed of trust, subsequent to that of plaintiff,, and went upon said premises to carry on a nursery business, not only with said stock, but with new stock, in pursuance with the terms of said contract with plaintiff, the consideration being money paid and to be paid by them to plaintiff, then said nursery stock, which was on said land when defendants took possession thereof, as well as that put on by them afterwards, was personal property, the removal of which by defendants, did not constitute waste.”
It is argued that, under the law, nursery stock passes with the real estate in a sale under a mortgage, and that consequently plaintiff, as owner of it,'can recover against defendants for removing it after the mortgage sale. Without pretending to dispute this proposition of law, I have only to say that according to the instruction the removal of the stock is not justified by the relation of the parties as fixed by their legal estates, but by license and agreement by the plaintiff. If the plaintiff made the agreement pleaded in the answer and defined in defendants’ testimony, which contemplated a removal of the nursery stock, like any other crop on the land, then the defendants could not be guilty of waste, in effecting such removal during the term or period covered by the agreement.
The fact that plaintiff had foreclosed his deed of trust in violation of the agreement could not affect the right of defendants under it. They could, notwithstanding such premature foreclosure, justify their acts under the greement by maintaining that the foreclosure as to them *93was inequitable. It is hardly necessary for me to add that, viewing the agreement even in the light of license, it was not revocable at the pleasure of plaintiff under the evidence in this case, showing the acts and expenditures of defendants on the faith of it. A person has no right to revoke a license to the injury of the grantee, in face of his contract or assurance to the contrary. Baker v. R. R., 57 Mo. 265; Bispham’s Eq., 237.
In another respect the plaintiff cannot justify his non-suit by this declaration of law. It need not affect his right of action, but only relate to a portion of damages claimed by him, under the designation of waste. A person is not instructed or forced out of court by a ruling which- may result only in cutting down the amount of damages claimed by him. As long as the rulings leave him a substantial cause of action, his withdrawal from the court is his own act and deprives him of the right of appeal. In Hageman v. Moreland, 33 Mo. 87., Judge Dryden remarks: “It is only where the action of the court, on the trial, is such as to preclude the plaintiff from a recovery, that it is proper to suffer a non-suit. In no other case will the court interfere, as has been decided again and again.” In passing upon the same question in Layton v. Riney, 33 Mo. 87, Judge Bay,- in giving the opinion of the court, speaks to. the same effect: “ It is only where the ruling of the court is such as strikes at the root of the case and precludes the plaintiff from a recovery, that we will undertake to review the action of the court below after a voluntary non-suit. A contrary practice would encourage parties to appeal upon every trivial decision of the court, and thus keep the matter in controversy in endless litigation.” 38 Mo. 87; 19 Mo. 647; 32 Mo. 322.
It would be vain in the court to consume its time in settling questions relating to the measure of damages, when the plaintiff, by his voluntary act in withdrawing his case, renders it impossible to know whether they would have ever come before the trier of facts for con*94sideration. If tlie plaintiff maintains Ms action by a verdict or finding- of -recovery, and fails to obtain the damages he -is legally entitled to, it will be time enough then to consider instructions which may possibly have -curtailed the amount of his recovery. If the verdict goes against him, it is evident that he cannot be injured by an ■erroneous ruling relating merely to the amount of damages incident to the rights-of recovery in his cause of .action. •
In our opinion the judgment should be affirmed, and it is so ordered;
AE-concur.
