Opinion by
This was an action of trespass, brought to recover damages for injuries alleged to have been caused to plaintiff’s property, by the defendant company. The plaintiff was the owner of a farm in Washington county, near the town of Donora, and the defendant company owned the underlying coal. During the process of mining, and by reason of its failure to leave proper support for the surface, the defendant company injured a portion of the surface for building purposes, interfered with the use of a private road, damaged the dwelling house, and destroyed certain springs of water.
The assignments of error relate solely to the measure of damages. The principal injury of which complaint was made, was the destruction of five springs of water. This injury was permanent and irremediable, as was also any damage to the surface which might render it less available for building purposes. Other injuries, such as the sinking of the dwelling house and
The first assignment of error complains of the admission of testimony as to the value of the springs -in themselves. This specification is sustained. The value of the springs was only an element in estimating the value of the realty. If the trespass resulted in permanent injury to the realty, the measure of damages is the diminution in the market value of the land. This principle is laid down in Schuylkill Nav. Co. v. Farr, 4 W. & S. 362, where it was held that the measure of damages is (p. 375), “the difference between what the property would have sold for as affected by the injury, and what it would have brought unaffected by such injury.” And in McKnight v. Ratcliff, 44 Pa. 156, an action for flooding the shaft of a coal mine, the measure of damages was held to be the actual injury sustained in delay, loss of time, damage to machinery, etc., and if the mine was irreclaimable, then the value of the estate and property.
In Hanover Water Co. v. Iron Co., 84 Pa. 279, it was held that the measure of damages for the diversion of a stream whereby a farm with an ore-bank thereon is injured, was the difference in the market value of the property as a farm and ore-bank, immediately before the diversion of the stream and immediately afterwards as affected thereby.
In Vanderslice v. Phila., 103 Pa. 102, an action for injuries through the bursting of a negligently constructed' sewer, Mr. Justice Teunkby said (p. 109) : “ Compensation for the loss is the measure of damages. Permanent injury done to the buildings, cost of repairs and the loss of rent for the time necessary to make the repairs, are elements affecting the market value, and the difference between that value in their injured condition and such value if uninjured, is compensation.”
The sound clear rule is stated in Seely v. Alden, 61 Pa. 302 ; Fulmer v. Williams, 122 Pa. 191; Williams v. Fulmer, 151 Pa. 405, and Thompson v. Traction Co., 181 Pa. 131, and is in substance that when the injury is permanent, the measure of damages is the difference in market value, before and after the injury, or the cost of removing the obstruction, whichever is the lower amount.
. It is suggested in tbe argument here, that the trial court considered the decisions of this court in Robb v. Carnegie, 145 Pa. 324, and McGettigan v. Potts, 149 Pa. 155, as establishing tbe doctrine, that in no instance, and under no circumstances is depreciation of market value the measure of damages
In so far as the property of the plaintiff in this ease was permanently injured, the rule should have been applied.
The judgment is reversed and a venire facias de novo is awarded.
