. The defendant in error, plaintiff below, recovered judgment against the plaintiff in error, defendant below, for damages for the alleged negligent destruction by fire of certain buggj.es upon defendant’s right of way, the buggies having therefore been consigned to her and shipped over defendant’s line of railway to Garland, Wyoming. The .specific acts constituting the alleged negligence were the permitting of rubbish and inflammable material to accumulate on defendant’s right of way and a defective spark arrester in defendant’s engine whereby sparks were allowed to escape, set fire, and spread from such rubbish to plaintiff’s property. At the close of the evidence the defendant moved the court for a directed verdict on the ground that upon the evidence the plaintiff was not entitled to recover. The overruling of this motion is here assigned as error.
Plaintiff’s evidence tends to show that the car containing the buggies arrived at Garland on or about the first day of November, 1904, and was set out and switched onto a side track. The buggies were in wooden crates and wrapped with paper and were shortly thereafter received and unloaded by her agent upon the right of way, from 10 to 20 feet from the side track, and permitted to remain there for the purpose of being set up until in the early morning of November 5th, 1904, they were discovered to be on fire and part .of them destroyed. That the regular train going westerly on the evening previous was the only train which passed the station the evening or night previous to the fire; it was a few minutes late and did some switching on the side track, and its engine was seen to emit an unusual quantity of sparks while so engaged and that it was a matter of general observation for a long time prior thereto that this particular engine had in passing that vicinity emitted a great quantity of sparks. That there was- a livery stable about 150 feet from the side track, which was north of the main line, and that dry manure interspersed with dry staw had been blown to and collected along the ties and rails, which *48were not ballasted, from the stable and corrals and was there at the time the buggies were unloaded and remained there up to the time of the fire. The track of the fire was shaped V, the apex being between the rails and the sides diverging and enveloping the place where the buggies were. The evidence of the defendant went to the perfect condition of its engine, due care in its operation, its proximity to where the fire occurred; that there was no wind to carry the sparks in the direction of the fire, that there was not an unusual' amount of sparks, and that there was no rubbish upon the right of way, and that the fire burnt toward and not from the track.
Contributory negligence was not pleaded as an affirmative defense. The answer was a general denial, except an admission as to defendant’s corporate existence. The issue upon the pleadings was the alleged negligence of the company in permitting its right of way to become encumbered with combustible material and defective equipment of its engine as the proximate cause of the damage. The established rule in such cases is that when a defendant relies upon contributory negligence as a defense he is barred from introducing evidence of such negligence unless he has pleaded it as a defense. Such plea constitutes an affirmative defense and the issue must be tendered by him in order to entitle him to introduce evidence in support of such defense. (Ency. Pl. & Pr., Vol. 5, p. 10.) This rule does not, however, bar the 'defendant from taking advantage of anything in the plaintiff’s evidence which ■defeats his right of recovery. In other words, the plaintiff must make out a case by the evidence, and if upon all of the evidence he is not entitled under the law to recover, that fact may be taken advantage of by the defendant.
The plaintiff in developing her case proved that she received the buggies by her agent when they were crated and wrapped in paper, unloaded them on the right of way about ten to fifteen feet from the side track, which was used for switching cars, amidst dry and combustible ma*49terial, where such material, as well as the paper and crates in which they were packed, were liable to be ignited from the sparks of passing engines, and permitted them to remain there for her own convenience without other excuse or justification, for the purpose of having her employee set them up. It may be conceded that the defendant was negligent in not keeping the right of way clear of inflammable material, and it may be further conceded that the fire was communicated by sparks from a passing engine, but there was also inflammable material placed there by the plaintiff. The crates, paper wrapping and buggies were in her control and custody, and with full knowledge of the surrounding conditions she placed and permitted them to remain upon the right of way. It makes no difference whether the initial point of the fire was in the rubbish or in the combustible material with which they were wrapped or crated. The proximate cause of the damage was leaving the buggies so wrapped and crated in such exposed condition as much as it was in the company in permitting rubbish to accumulate on its right of way and setting fire thereto by sparks from its engine. This is not a case where the fire spreads to and destroys' property outside of the right of way, or where the fire is originally set by sparks of a passing engine outside of the right of way, but upon plaintiff’s own testimony where the company had delivered the property to the owner, wrapped in combustible material, who assumes to leave it upon the right of way in proximity to passing engines, and in the midst of combustible and inflammable material. There is no evidence of wanton or intentional destruction of: plaintiff’s property.
The question of negligence is a mixed question of law and fact. Where the facts are not in dispute, that is to say, where there is no conflict in the evidence, the question of the right to submit it to the jury is one of law and to be determined by the court. The rule in such cases is that if the evidence tends to prove negligence on the part of the defendant as the proximate cause of the injury, the question should be submitted to the jury, unless *50upon the whole evidence it is apparent.that the.act complained of was the result of the joint negligence of the plaintiff .and the defendant or that the injury or damage would not have occurred except for the negligence or want of reasonable care upon the part of the. plaintiff. This rule.does not apply where the injury complained of is the result -of a wanton or intentional act, which is not the case here.
Although contributory negligence was not pleaded as .a defense, yet the undisputed evidence shows plaintiff to have been guilty of contributory negligence, which resulted in the loss of her property. Upon the facts she assumed the risk of its loss by leaving it on the right of way wrapped and crated in combustible material, and upon her own evidence, in the midst of inflammable material, where it was exposed to and liable to be ignited from the sparks from passing engines. This was negligence per se but for which her property would not have been destroyed, and was a proximate cause'of the damage which she .seeks in this action. It was developed by her evidence in making out her case and defeated her right of recovery. Upon the record the court erred in not granting the motion for a directed verdict. (Boswell v. Bank, 16 Wyo. 161; Riner v. New Hampshire Ins. Co., 9 Wyo. 81, 446; Kahn v. Traders’ Ins. Co., 4 Wyo. 419; McMurtry v. Railroad, 67 Miss. 601, 7 So. 401; Brown v. Railroad, 41 Wash. 688, 84 Pac. 400; Engleking v. Railroad, 187 Mo. 158, 86 S. W. 89; Chaney v. Railroad, 176 Mo. 598, 75 S. W. 595; Hudson v. Railroad, 101 Mo. 13, 14 S. W. 15; Murray v. Railroad, 73 Tex. 2.)
The court, though requested to do so, refused to instruct the jury on the question of contributory negligence. Had there been a conflict in the evidence as to whether her acts were excusable or justifiable, it would have been proper to have instructed the jury on that phase of the case. (Railroad v. Belt, (Tex. Civ. App. April 21, 1898.) 46 S. W. 374; Railroad v. Allbright, 7 Tex. Civ. App. 21, 26 S. W. 250; Bunnell v. Railroad, 13 Utah, 314, 44 *51Pac. 927.) As already stated, as a matter of law, plaintiff s contributory negligence was conclusively shown by her own evidence in the development of her case.
For the error complained of the. judgment will be reversed and the cause remanded for a new trial.
Reversed.
