1 I. Plaintiff occupied a part of defendant’s right of way on the. depot grounds from 1878 until 1894 without rent charge, as a tenant at will. In the latter year the company’s agent advised the local manager of Nielander & Co. that the company would expect the firm to sign a lease for all business done on the right of way, and on April 24th the latter made this application to the defendant’s division superintendent on a printed form prepared by the company: “The undersigned, Nielander & Go., P. 0. *422address, New Albín, la., desire to lease, subject to the company’s usual terms and conditions, a part of its depot grounds at this station for tbe purpose of erecting and maintaining thereon a grain warehouse, and request that such ground may be located on the northwest side of main track and northwest side of station, and have a track frontage of 139 feet.” Thereupon a lease for a term of three years, beginning July 1, 1894, was prepared by the company, and signed by the firm, though with this notation: “Agreeing to all but the second condition.” The second condition, it should be said, exempted the company from liability for damages occasioned by the negligent operation of the trains. When informed that the lease would not be'accepted with the notation, it was erased by plaintiff. It appears that the precise location of plaintiff’s property had been fixed by a careful survey, using as a point of beginning the intersection of the center of the main track with the east side of Oak street.' In preparing the lease a doubt arose as to whether this- point was on the east or west line of the street, and, being referred to the local agent, who had assisted in the survey, he erroneously declared it to be on the west line, and the lease was mistakenly drawn so as to locate the property the width of the street west of where it really was. As a result, only the annex is within the description. At the expiration of three years, a new lease, embodying the same mistake, to continue one year, and until terminated upon 60 days’ written notice, was executed. It seems, in the operation of the railroad general directions only are considered, — that is, the track leading toward Chicago is spoken of as east, and that toward St. Paul as west, regardless of the direction of the track locally, — and that the mistake was occasioned by the agent inadvertently reporting with respect to this custom, rather than the points- of the compass. That there was a mistake on the company’s part is manifest. But it is insisted that this was not mutual; that plaintiff merely acquiesced in what was proposed, and consented to the contract prepared by the company alone. Tin-*423questionably, land other than described in the lease must be shown to have been the subject of this contract before it can be reformed. The inquiry in such a case is always directed to the ascertainment of what was really the subject of the agreement. Had the parties the land described in mind in making' the lease, or some other ? If they had some other, and the arrangement was made in reference to that, then clearly there has been a mutual mistake for then their minds have met, not with relation to the subject-matter described, but another, not expressed. The question is not whether there lias been a previous agreement in parol, but whether the subject of the agreement as made was that stated in the lease, or some other, which the party through mistake failed to accurately describe. The policy of the defendant had evidently undergone a change at about this- time, possibly as a result of the decision in Griswold v. Railway Co., 90 Iowa, 265, and all occupying right of way or depot grounds were required to procure leases with certain conditions, in which a rental of $5 per annum was reserved. The plaintiff’s local manager was advised of the necessity of the procurement of a lease, and the application signed pointed out in a general way the land on which the elevator and annex were situated. True, the application was for ground “for the purpose of erecting and maintaining thereon a grain warehouse,” and it should be said a new elevator replaced the warehouse on the same foundation during the term of the first lease. The firm had occupied the ground for many years, and had no purpose of making use of any other portion of the depot grounds. What was it plaintiff applied for? For the ground already occupied, and on which to maintain its buildings in which it continued its business, or some other, for which it had no qiossible use? Was ground on which the annex stood desired, and not that under the elevator, when both formed part of the same structure ? It is idle to claim, in the face of this record, any other than that possessed as a tenant at will was the subj ect of this application. True, the answer avers that *424tbe'application was tbe result of a demand on tbe part of the company'tbat a lease be taken. If so, wbat land did tbis demand refér tó ? To tbat occupied and in use by the plaintiff, or tbat in wbicb it bad no concern ? Circumstances are often qfiite as'potential as words in pointing out tbe subject of a contract, and we think these, apart from anything contained' in tbe lease, fix tbe ground concerning wbicb tbe parties understood they were contracting as tbat on wbicb tbe building was located. Tbat such was their understanding is strongly confirmed by their subsequent conduct. Tbe description in tbe lease in controversy was copied from tbe first one drawn, and whatever occurred before its execution may be considered as bearing on tbe .understanding with wbicb it was entered into. Eent was paid for tbe three years during tbe continuance of tbe first lease. Por wbat? The land occupied by plaintiff, and tbe track frontage, or tbat merely on wbicb the annex stood, and other ground unused by iffaintiff, with tbe elevator unprovided for ? In October, 1895, -the defendant granted permission to use a gasoline engine on condition tbat tbis should “not be construed so as to impair any of tbe conditions in lease of ground upon wbicb your elevator is located.” To tbis plaintiff expressly assented. Tbe writing of tbe notation indicated a supposition tbat tbe building was included in tbe lease, else plaintiff would not have excluded tbe clause relating to damages by fire in signing it. Tbe first lease stipulates tbat tbe premises are to be used and occupied exclusively as a site for a warehouse for storing and handling grain transported aiid to be transported over tbe line of tbe railroad company. Had tbe parties any understanding, then, prior to tbe execution of the second lease ? But one conclusion can reasonably be drawn from tbe circumstances pointed out, and tbat is they were contracting with respect to ground occupied by plaintiff for so many years as tenant at will. Had defendant undertaken to enforce tbe removal of tbe part of the building not included in tbe description, could any one doubt tbe plain*425tiff’s right to have the lease reformed so as to include it ? On precisely the same principle the defendant may insist on the correction of this instrument to meet the understanding and intention of these parties in executing it. As tending to support our conclusion, see Jenkins v. Jenkins University, 17 Wash. 160 (49 Pac. Rep. 247); Improvement Co. v. Marshall, 57 Minn. 333 (59 N. W. Rep. 294).
2 II. Appellee urges that relief should be denied because of culpable negligence on the part of the defendant. Possibly, the local agent was negligent in misinforming the superintendent. This cannot, however, be said of the latter. Indeed, there is more room for attributing to him special care in making inquiry, even after the survey, and apparently to make assurance doubly sure. It is not uncommon for people to become confused in the matter of directions, and it was evidently to avoid possibility of this that confirmation of what was shown in the plat was sought from one familiar with the locality for many years. Whether the superintendent made a minute on the plat of the side of the street at which they begun does not appear. The local agent had nothing to do with the preparation of the leases. He merely assisted the officers in charge of that work as called on, and we do not think the company should be denied relief because of the negligence of such employe. But for the oversight of some one, cases of this character would be rare. As said by Mr. Pomeroy in his work on Equity Jurisprudence (section 856) : “It is not every negligence that will stay the hand of the court. The conclusion, from the best authorities, seems to be that the neglect must amount to the violation of a positive legal duty. The highest possible care is not demanded. Even a clearly established negligence may not of itself be sufficient ground for refusing relief, if it appears that the other party has not been prejudiced thereby.” In this case not only has the plaintiff suffered no prejudice, but the very purpose of defeating the relief demanded is to obtain an advantage to which it is not *426-entitled. No one charged witb the duty of contracting with plaintiff appears to have been remiss in the performance of his duties, and we think the case proper for the interposition of equity. The relief prayed should have been granted.— ^Reversed.
