This appeal presents for our consideration three alleged errors—all relating to the rule adopted by *144the court below for assessing the amount to be paid appellant as compensation for taking his land for a railroad.
i. It is insisted that compensation should have been assessed with reference to the value of the land taken as of the time of filing the petition, and not as of the time of the entry upon the land by the corporation.
Upon this question the courts in different States have established different rules. It is held by some that the assessment should be made with reference to the time of entry; by others, with reference to the time of filing the petition; and by still others, with reference to the time of the award. Lewis on Eminent Domain, sec. 477 and cases cited. The court below adopted the first rule, against the objection of the appellant who contended for the second one. We recall no case in which the question has been presented for the decision of this court; but there are references by the court to it, and, in so far as they indicate an opinion, it is favorable to the contention of appellant.. Either rule is liable to operate harshly in special cases—as., well against the land owner as the corporation—but we see nothing in the one contended for which indicates that it would more often work harshly than either of the others ;. and it has the advantage of fixing a certain and definite time with reference to which the estimate must be made. Besides the corporation has the right to acquire the land;. when it files its petition, it declares its purpose to appropriate it and to render just compensation to the owner. Until it has done that, it is in default; but afterwards it can do nothing more until, in the regular course of procedure of the courts, a legal ascertainment of the amount to be paid is-made. As the filing of the petition is the attempt to assert the right of condemnation, and subsequent delay is without fault of either party, it seems fair to each alike that the assessment should be made with reference to value as of that date. Lewis on Eminent Domain, sec. 477 and cases ; Burt v. Merchants' Ins. Co., 115 Mass., 1; The South Park Com'rs v. Dunlevy, 91 Ill., 49.
*145There was evidence tending to prove that the land had advanced in value between the time of entry and that of filing the petition, and 'we cannot hold that the error of the court in making its assessment with reference to the earlier date did not prejudice the appellant. For this error, the judgment must be reversed ; and as the other points raised1 will be presented in the future trial of the cause, it is proper that we determine them.
2. It is assigned as error that the court ruled “that Newgass was entitled to recover nothing for fences or overfiow.”
2. Damage for fencing. The appellant was entitled to be compensated for the taking of his land—to no more and to no less. If the taking impaired the value of his contiguous land, he was en titled to be compensated to the extent of such impairment, in addition to the value of that taken. If, in view of the probable future use of the remainder, additional fencing would be necessary, and this fact rendered it less valuable than it would otherwise have been, then such fact would be an element of damage. Such damage is not necessarily the cost of increased fencing, but the amount of depreciation in the value of the land caused by the increased burden upon its use. There is nothing in the proof to show that, in order to use and enjoy the lands, as they probably would be used in future, any additional fencing would be necessary. There was therefore no error in the court’s ruling in that regard. Lewis, Em. Domain, sec. 498 and cases cited ; Railway v. Combs, 51 Ark., 324.
«9. Damage for overflows. If the appropriation of the part and its use as a railroad resulted in flooding the remainder of appellant’s lands, the damage so occasioned should be included in the assessment; but no account should be taken of injuries thereafter to result from an improper construction or maintenance of the bed, for the condemnation does not authorize either, and the corporation that condemns the land will be liable for such injuries as may thereafter result therefrom. Railway v. Rhea, 44 Ark., 258 ; Railway v. Henry, id., 360.
*146 4. Value ot i. It is insisted that the court erred in refusing to include, in its estimate of the value of the land taken, the value of a railroad previously constructed upon i't by the appellee or its vendors. It is argued that the railroad was built on it by a trespasser; that it became a part of the land, and as such passed to the landowner; that when the petition was filed, the railroad was as much the property of the appellant as the soil itself, and could not be taken from him without just compensation.
There is an old maxim that “ Whatever is affixed to the soil, belongs to the soil; ” and it is a general rule of the common lav/ that a trespasser who builds on another’s land dedicates his structure to the owner. The reason of the rule, which has been often stated, is that the entry was a trespass to the injury of the owner, and that the trespasser could not add further injury by tearing down and removing the building, for in that the law contemplates that an injury to the soil will result as a necessity. The trespasser has no legal right to acquire the soil, and when he places on it a building which can not be removed without some injury to it, it will be presumed that he intended to dedicate the building to the use of the land, and not that he contemplated a second trespass. He could not remove the building, for its severance would damage the soil; he could not exact pay for it, for he could not impose upon the owner of the soil an obligation to pay for improvements which he had not authorized and may not have desired. Those reasons fail when applied to the case at bar. The corporation had the right to enter upon the land for purposes of survey, and to appropriate it on making just compensation. It is therefore not necessary to presume that, when it built its railroad, it intended either to dedicate it to the use of the land, or to commit another trespass to the damage of the land ; but it is more reasonable to presume that it intended to retain the railroad for use as such, and lawfully to acquire the land upon which it rested. The railroad was not built to improve the ground or to enhance its ordinary utility, but to be used *147as part of an easement for public purposes, entirely independent of the ordinary uses of the ground. To the rule relied upon exceptions have always been recognized, increasing with the importance and value.of personal property and with the demands and exigencies of society; and, as its reasons fail in this case, we do not think it should control.
All that the constitution guarantees or the law demands is that just compensation shall be made to the owner in return for property appropriated by the public. A rule that would exact of a corporation the payment of a sum to cover the value of a railroad as such, constructed at its own expense, would go beyond the demands of justice, and could find no sort of countenance in conscience or in law outside of the strict letter and fanciful presumptions of the rule stated.
The same question has been often adjudicated by the courts of the highest dignity and learning in sister States, and the decided weight of adjudged cases is against the appellant. Aside from adjudication, reason and justice condemn the contention. Justice v. Nesquehoning, etc., Ry. Co., 87 Pa. St., 28; Toledo, etc., Ry. Co. v. Dunlap, 47 Mich., 456; The Chicago, etc., Ry. Co. v. Goodwin, 111 Ills., 273; Lewis, Em. Dom., sec. 501 and cases cited; Jones v. N. O., etc., Ry. Co., 70 Ala., 227; Searl v. Sch. Dish, 133 U. S., 553 ; Lyon v. Green Bay, etc., Ry. Co., 42 Wis., 538.
In most of the cases relied upon by the appellant the claim to improvements was presented in such' form that, if it were sustained, a separation of the improvements from the land would become necessary, or some other prejudice result to the land owner. But neither would result in this case, for the corporation acquires the land, as it lawfully may do, upon the payment of just compensation, and holds the road built thereon at its own expense without cost or detriment to the appellant.
The injury resulting to the appellant from the unauthorized entry might have been promptly checked and redressed, if need be, by an appeal to the courts. That it was borne *148so long, argues that it did not assume a violent or aggravated form.
The measure of compensation is the value which the land taken would have had at the time of filing the petition, if the road had not been constructed on it, together with the difference between the present value of the owner’s contiguous land, with the road constructed where it is, and what would have been its present value if the road had not been built. Lyon v. Green Bay, etc., Ry. Co., 42 Wis., 538. And in determining as to the value of the land taken, any appreciation or deterioration that may have resulted to it specially by reason of the building of the road on it will be disregarded, but such as may thereby have resulted to it, in common with other lands in the same community, will be considered.
As the corporation has been in the enjoyment of the land, the damages assessed will bear interest from the date of filing the petition.
For the error indicated, the judgment will be reversed,, and the cause remanded for further proceedings.
