This is a suit in equity to collect certain cash . rent claimed from the defendant, Hughett, and to enforce a landlord’s lien against certain corn sold by Hughett to the defendant Farmers Terminal Elevator Company. The answer of the defendant Hughett consisted of a general denial and a counterclaim. The defense of the elevator company consisted of a plea that the plaintiffs had waived their lien and were estopped to enforce it. The court entered decree in favor of the *592 plaintiffs for the rent sought and dismissed the counterclaim. Hughett has not appealed. The court denied the relief sought by plaintiffs against the elevator company. Plaintiffs appeal from this part of the court’s decree.

The plaintiffs are the owners of a farm of approximately 200 acres situated near Fort Dodge. The farm was owned for many years by a Collins family. Suit was instituted to partition the property. The sale was had, plaintiffs purchased the property, and entered into possession in June, 1937.

There is situated on the farm a gypsum mine and mill operated by the Cardiff Gypsum Company under a 50-year royalty lease. The surface of the farm was leased by the Col-linses to the defendant Hughett for the year March 1, 1937 to March 1, 1938. Plaintiffs acquired the property subject to such lease. It was an oral lease, pursuant to which Hughett agreed to pay as rent one half the corn, two fifths the oats, $100 in cash for the pasture and to shell the corn.

The plaintiff Sensibar is the president, and the plaintiff Breen is the vice-president of the Cardiff Gypsum Company, and the two of them own a controlling interest in the corporation. Sensibar is a nonresident. Breen is practicing law at Fort Dodge. Francis Scott is the mine superintendent for the Cardiff Gypsum Company, and one Loomer is the plant manager. In November, 1937, when Hughett undertook to pick the corn on the place, Scott was notified by Breen to take charge of the division of the corn and to see that the plaintiffs got their share. The corn was picked by a mechanical corn picker and the arrangement between Scott and Hughett was that every other load of corn was to be placed in a crib on the farm, and was to constitute the landlord’s share. This arrangement was carried out satisfactorily. Scott testified that he was looking after Breen’s interests. He saw Hughett haul his share of the corn away from the place in the direction of the elevator, but was not interested and made no objection.

G. L. Spike, the manager of the defendant Farmers Terminal Elevator Company, testified that he purchased 598 bushels of corn from Hughett, of which 491 bushels came from the plaintiffs’ farm. He advanced Hughett $100 on the corn, then, after some of it had been delivered, paid him an additional $100. When all of it had been delivered, he paid the balance of $27. *593 After tbe first load of com was delivered, Spike called tbe mill of tbe Cardiff Gypsum Company. He did not know witb whom be talked. According to Scott, it must bave been tbe plant manager, Loomer. According to Spike, be called tbe mill and told them that Hugbett was hauling in corn and asked if it all belonged to Hugbett or was to be divided and they said tbey bad tbeir man dividing tbe corn in tbe field.

At the close of tbe evidence, tbe elevator company moved for a dismissal of tbe petition as to it, for tbe reason that it affirmatively appeared in tbe record that tbe plaintiffs bad knowledge of tbe sale of tbe corn by Hugbett before the full purchase price was paid to Hugbett, made no objection thereto, and failed to notify tbe elevator company of plaintiffs’ lien so that plaintiffs are estopped from demanding payment from tbe elevator company. Tbe court found in favor of tbe elevator company. Tbe only question presented for our decision is whether or not tbe court erred in so bolding.

Tbe landlord’s lien which plaintiffs seek to enforce arises by virtue of the provisions of section 10261 of the Code. Since this suit was commenced in February, 1938, tbe suit was timely, in accordance with tbe provisions of section 10262 of tbe Code. In tbe early case of Holden v. Cox, 60 Iowa 449, 15 N. W. 269, this court recognized that the statutory landlord’s lien is not divested by a sale of the crops by tbe tenant, but tbe landlord may follow tbe crops into tbe bands of tbe purchaser and, if be has disposed of them, be will be liable to tbe landlord in damages. This decision is cited with approval in the ease of Wilson v. Fortune, 209 Iowa 810, 811, 229, N. W. 190, 191, 67 A. L. R. 1075, wherein we state:

“Tbe law in this state is settled that a landlord whose lien has been destroyed or lost by reason of tbe sale of tbe property by the tenant may maintain an action against tbe purchaser for conversion unless be has waived, or is estopped from asserting, his lien. Blake v. Counselman & Co., 95 Iowa 219; Holden v. Cox, 60 Iowa 449; Scallan v. Wait, 64 Iowa 705; Rew v. Maynes, 147 Iowa 15. * * * Waiver or estoppel is an affirmative defense, tbe burden of proving which is on defendant.”

In tbe case of Wright v. E. M. Dickey Co., 83 Iowa 464, 50 N. W. 206, this court held that, where a landlord has a lien on the crops for the rent of the farm, but permits the crops to *594 be harvested and carried to market and there sold to a purchaser without notifying the purchaser of his lien, the landlord is estopped from asserting any claim to the crops sold as against such purchaser. This case was cited with approval in the case of Strasberger v. Farmers Elevator Co., 184 Iowa 66, 69, 167 N. W. 184, wherein this court approved an instruction which advised the jury that, in an action to enforce a landlord’s lien against the purchaser of hogs sold by the tenant, upon which the landlord had a lien, if the agent for the landlord knew of or consented to the selling of the hogs, or if, after the hogs were sold and before they were paid for, he made no objection thereto and failed to notify the purchaser of the landlord’s lien, then the landlord would be estopped from demanding payment from the purchaser.

In the case of Fishbaugh v. Spunaugle, 118 Iowa 337, 341, 92 N. W. 58, 60, this court states:

‘ ‘ It is a settled doctrine that the principal is bound not only by acts of his agent within the express limit of Ms instructions, but is also bound to the extent of the apparent authority conferred upon such agent.”

In that case, a landlord sought to enforce his lien against the purchaser of grain from the tenant. Certain special interrogatories were submitted to the jury upon which the jury reported that the landlord’s agent knew that the tenant was selling corn covered by the lien to the purchaser, authorized the tenant to sell and deliver the corn, but that the purchaser was not induced to purchase the corn by any knowledge or information of any act on the part of the agent, and that the agent had no authority to waive the lien. There was a general verdict for the defendant. On appeal, the plaintiff contended that the answers to the special interrogatories were fatal to the general verdict. This court held that, notwithstanding the fact that plaintiff’s argument was plausible, the general verdict should stand, this court holding that it was not necessary that the agent should have express authority to release the corn in order to bind the landlord, that the agent may in fact have no authority and yet if, under all the circumstances, his consent to the sale of the corn was within the apparent scope of the power given him by the landlord, then the latter will be bound by *595 such, consent and the lien will be held to have been relinquished as against the purchaser.

Under the record herein, Scott, as agent for the plaintiff, had no express authority to waive the lien or to consent to the sale of the corn by Hughett. However, Scott admitted that he knew Hughett was hauling the corn to the elevator. He made no objection. He was not interested. The arrangement which Breen made with Scott was such that, when Spike called the mill to report that Hughett was selling the corn to him and to inquire whether it was Hughett’s corn, whoever answered the telephone was justified in assuming that Scott was protecting the plaintiffs’ interest in the corn, and that it was proper for Hughett to sell it to Spike. The answer which was given to Spike justified Spike in believing that it was safe for him to buy the corn from Hughett. At the time that this conversation took place, there was more than enough money unpaid to protect the plaintiffs’ lien. Had Spike been advised of the plaintiffs’ lien, the plaintiffs could have been protected.

In the case of Wright v. E. M. Dickey Co., supra, in holding that the landlord could not enforce his lien against the purchaser of the crops, we state, 83 Iowa, at page 468, 50 N. W. at page 206:

“It is a familiar principle that, where one of two innocent parties must suffer for the wrongful act of another, the one who rendered the wrongful act possible must bear the burden. ’ ’

The circumstances shown by the record herein were sufficient to justify the trial court in determining that, as between the elevator company and the plaintiffs, the plaintiffs, rather than the elevator company, rendered the wrongful act of Hugh-ett possible, and should be the ones to suffer on account of it. We are not disposed to disturb this finding of the court.

The decree is affirmed. — Affirmed.
