We fail to discern from the record any evidence of negligence on the part of the railroad company which contributed to the plaintiff’s injury. Even if the engineer or fireman did fail to ring the bell or sound the whistle, of which there is only negative testimony with positive evidence to the contrary, still the defendant had a right to operate the train over its track, and the negligence of the driver of the automobile is so palpable and gross, as shown by plaintiff’s own witnesses, as to render his negligence the sole proximate cause of the injury. Construction Co. v. R. R., 184 N. C., 179, 113 S. E., 672.
Upon all the evidence, we think it is manifest that the alleged negli- . gence of the defendant, Atlantic Coast Line Eailroad Company, was not in law a proximate cause of plaintiff’s injury.
Speaking to the subject in his valuable work on Negligence (138), Mr. Wharton very pertinently says: “Suppose that, if it had not been for the intervention of a responsible third party, the defendant’s negligence would have produced no damage to the plaintiff: is the defendant liable to plaintiff ? This question must be answered in the negative, for the general reason that causal connection between the negligence and damage is broken by the interposition of defendant’s responsible human action. I am negligent on a particular subject-matter. Another person, moving independently, comes in and, either negligently or maliciously, so acts as to make my negligence injurious to a third person. If so, the person so intervening acts as a nonconductor and insulates my negli*720gence, so that I cannot be sued for the mischief which the person so intervening directly produces. He is the one who is liable.”
The same rule announced by Mr. Justice Strong in R. R. v. Kellogg, 94 U. S., 469, regarded as sound in principle and workable in practice, has been quoted with approval in a number of our decisions. He says: “The question always is, was there an unbroken connection between the wrongful act and the injury — a continuous operation? Did the facts constitute a continuous succession of events, so linked together as to make a natural whole, or was there some new and independent cause intervening between the wrong and the injury ? It is admitted that the rule is difficult of application. But it is generally held that, in order to warrant a finding that negligence, or an act amounting to a wanton wrong, is the proximate cause of an injury, it must appear that the injury was the natural and probable consequence of the negligence, or wrongful act, and that it ought to have been foreseen in the light of attending circumstances.”
"Where the plaintiff’s evidence shows that his injury was due to the negligence of a third person, and not to that of the defendant, it is proper to nonsuit the action, for he thus fails to make out a case against the defendant. Such was the holding of the trial court, and the judgment is affirmed. Ballinger v. Thomas, 195 N. C., 517, 142 S. E., 761.
