Opinion by
Mb. Justice Heydbick,The plaintiff, an infant of less than four years of age, brought suit in the court below to recover damages for injuries *148received in the same accident out of which Jackson Twp. v. Wagner, 127 Pa. 184, grew. According to the plaintiff’s witnesses, he started, in-company with his mother, two younger children and Miss Wagner, the plaintiff below in Jackson Twp. v. Wagner, to drive over one of the highways of the defendant ■ township. At this time there was upon the side of the road in question a stone pile about twenty-five feet in length by from one to three feet in height, and at the side of the stone pile a hole in respect to the dimensions of which these witnesses differed widely, varying as to the depth from eight to eighteen inches; as to the width, from eight inches to three feet, and as to the length from one foot to five feet. The same witnesses differed as to the width of the road between this hole and the gutter almost as much ; one of them asserting that it was but seven or eight feet, while four others testified that it was from twelve to fourteen feet wide. Upon this evidence, to which greater credit seems to have been given than to that on the part of the defendant, the jury found, under proper instructions as to the duty of the supervisors, that the road was not, on the day and at the place of the accident, suitable and sufficient for public travel conducted in the ordinary manner and by the ordinary means of conveyance. It must therefore be assumed that the township was guilty of negligence; and as there could be no question of contributory negligence on the part of an infant of such tender years as the plaintiff, the only question to be determined is whether upon the farther facts testified to by the plaintiff’s witnesses the township is liable for the injury sustained by the plaintiff upon this road.
Whatever the condition of the road may have been the party passed over it safely and without noticing’ any defect therein, but when they had reached a point about one hundred and twenty feet beyond the stone pile, where the road was in good condition, they met a donkey drawing a cart loaded with tin cans, and another donkey which in the language of the witnesses was “ loose and came towards the horse.” Thereat the horse became frightened, the driver lost control of him, and he turned suddenly around, wrenching the spokes of one of the front wheels out of the hub, and fled in the opposite direction, the hub of the broken wheel falling to and dragging upon the ground. When the buggy reached the hole already described *149the end of the axle dropped into it and the plaintiff was thrown out upon the stone pile. The testimony upon the part of the defence showed very clearly that the occurrence was as is stated "by the reporter and in the opinion in Jackson Twp. v. Wagner, supra, differing somewhat from the foregoing statement, but in considering the assignments of error in this case the plaintiff’s testimony will be accepted as verity. So accepting it, was the defendant township answerable for the injury received by the plaintiff ?
It is a general rule as well settled as anything in the law of negligence that a man is responsible for such consequences of his fault as are natural and probable, and might therefore be foreseen by ordinary forecast, but if his fault happen to concur with something extraordinary, and therefore not likely to be foreseen, he will not be answerable for the extraordinary result. This rule applies in actions against municipal and quasi municipal corporations as well as to natural persons and private corporations. The concurrence of that which is ordinary with a party’s negligence does not relieve him from responsibility for the resultant injury. Examples of such concurrence may be found in cases where by reason of causes known to the public authorities horses are likely to become frightened and in their sudden fright plunge over an unguarded precipice, or rush upon some danger within the highway for the existence of which the authorities are responsible. In such cases the consequences of the neglect of duty are natural and probable and ought therefore to be foreseen. But when, from extraordinary causes, for the existence of which the supervisors are not responsible and of which they cannot be presumed to have had notice, a driver loses control of his horses' and they come in contact with a defect in the highway, there is no more reason for holding the township answerable for a resultant injury than there is for holding any other party responsible for tjie result of the concurrence of something which he could not foresee with his negligence. In Massachusetts it was held in a well considered case that when a horse by reason of fright, disease or viciousness becomes actually uncontrollable so that the driver cannot stop him or direct his course, or exercise or regain control over his movements, and in this condition comes upon a defect in the highway, or upon a place which is defective for *150want of a railing, by which an injury is occasioned, the town is not liable for the injury, unless it appears that it would have occurred if the horse had not been so uncontrollable: Titus v. Inhabitants of Northbridge, 97 Mass. 258. The doctrine of this case was reiterated in Horton v. Taunton, 97 Mass. 266 ; Fogg v. Nahant, 98 Mass. 578, and Stone v. Hubbardston, 100 Mass. 49. Similarly it has been held in Wisconsin that a town is not liable for an injury received upon a defective highway by a horse that has escaped from the control of its driver, unless it be made to appear affirmatively that the disability of the driver to control him was caused by the same or some other defect in the highway : Jackson v. The Town of Bellevue, 30 Wis. 250. In Maine also the same subject has been much considered, and with the like result: Moore v. Abbott, 32 Me. 46 ; Coombs v. Topsham, 38 Me. 204; Anderson v. Bath, 42 Me. 346; Moulton v. Sanford, 51 Me. 127. In the latest of these cases it was determined that if there be two efficient, indepen* dent proximate causes of an injury sustained by a traveler upon a highway, the primary cause being one for which the town is not responsible, and the other being a defect in such highway, the injury cannot be said to have been received through such defect, and the town is not liable therefor, though the traveler himself is in no default. It is true that in these states there are statutes defining the right of action for such injuries, but they are merely declaratory of the common law.
This precise question has not been as frequently considered in this state as in the states referred to, but in Chartiers Twp. v. Phillips, 122 Pa. 601, it was distinctly raised by a point in which the court was asked to charge that “To render a township liable for an injury by a defect in a highway it must have been the sole efficient cause of the injury, and if the juiy find from the evidence that this accident to the plaintiff was caused by the uncontrollable struggle of a choking horse, or from this cause concurring with a defect in the highway, then their verdict must be for the defendant.” For refusal to affirm this point without qualification the judgment of the common pleas was reversed. To the same effect is Herr v. The City of Lebanon, decided at this term. These judgments require no vindication. They are logical deductions from the rule of law which must be invoked by every plaintiff who seeks redress *151for an injury received through, the negligence of another. The injury must have been the natural and probable result of the defendant’s negligence. But the cases must be rare in which an injury can be said to be the result of the negligence of a party when there is another and primary efficient proximate cause, wholly independent of such negligence and for which the party charged with negligence is in no waj^ responsible. In such cases it would be incumbent on the plaintiff to show that the accident would have happened without the concurrence of the primary efficient proximate cause.
In this case the driver lost control of the horse the moment he took fright at the donkeys and tin cans, and she had not regained efficient control at the moment of the accident. Her own testimony is that she was trying to stop' him, but had not succeeded. He was still pursuing his flight dragging the wrecked buggy after him when the occupants were thrown out. It may be conceded that the township would have been answerable for the injuries if it Had appeared that the plaintiff would have been thrown out in the same manner if the horse had not received this extraordinary fright and wrecked the buggy but this did not appear. On the contrary it appeared in the plaintiff’s evidence that the party had passed the place of the accident in safety a few minutes before without noticing any defect. But for the fright of the horse and the driver’s loss of control they would have continued their journey, and of course the accident would not have happened. How much the wreck of the buggy may have had to do with the final catastrophe may be inferred from the account given by plaintiff’s witnesses and the belief expressed by the driver that if the wheel instead of the hub had gone into the hole the buggy would not have been upset. But the loss of the wheel was not in any manner attributable to any defect in the highway. It was admitted that the road was in good condition at the point where this beginning of the accident occurred. It is therefore clear that 'the proximate cause of the plaintiff’s injury was the fright of the horse, and that that fright was not caused by any defect in the highway or by any neglect of duty on the part of the supervisors.
For this reason the judgment must be reversed.
