Defendant noted an exception to the evidence of two witnesses for plaintiff, Martin Hairr and wife, to the effect that one week *215before tbe fire in question the engine operated by defendant over his tramroad, in passing the witness, threw out sparks and live coals from which fire caught. In this connection'it was also proved that defendant owned and operated only the one engine over his road, and under our decisions applicable the evidence is competent on the issue. Whitehurst v. Lumber Co., 146 N. C., 588; Knott v. R. R., 142 N. C., 238. In addition it appeared from the evidence of Andrew Robinson, defendant’s engineer and a witness in his behalf, that the engine in question was in the same condition on the day of the fire that it had been for six months previous to the fire, and continued to be for six months thereafter. This in any event would render the evidence receivable on the issue. Blevins v. Cotton Mills, 150 N. C., 493.
It was further insisted that his Honor erroneously modified certain prayers for instruction by defendant in reference to the conduct of one Tom Wright, who was engaged with others in the endeavor to extinguish or check the spread of the fire, the prayers more directly involved being as follows:
(a) “The defendant contends that the fire originated off his right of way and some distance from it, and that he was in no way responsible for this fire, but that from whatever cause originated this fire was held under control and was not permitted to go across the sand-clay road and was not communicated to the plaintiff’s land, and that the fire which burned the lands on the east side of the sand-clay road was set out by a third party, viz., one Tom Wright, and this is the fire that eventually burned the plaintiff’s land. If this is true, and the jury should so find by the greater weight of the evidence, then the defendant is not liable. Or if you shall find by the greater weight of the evidence that there was another fire set out by Tom Wright on the east side of the sand-clay road, as contended for by the defendant, and you are then in doubt as to whether the original fire or the fire set out by the third party, Tom Wright, burned the plaintiff’s land, in that event the defendant is not liable, and the plaintiff could not recover.”
(b) “If the jury shall find from the evidence that the fire originated between the defendant’s railroad track and the county sand-clay road, which runs parallel with the railroad track and several hundred yards east therefrom, and that while those assembled endeavoring to control the fire and while it was a considerable distance from the sand-clay road, which road was about thirty feet wide and free from combustible matter, one Tom Wright, a third party, instead of back firing along the sand-clay road on the west side of the road and next to the fire, strew fire on the opposite side of the road, being the eastern side of the road, with the wind blowing in an easterly direction, this would be an act of negligence for which the defendant would not be liable.”
*216His Honor, both in his general charge and in direct response, told the jury that the positions embodied in those instructions would prevail in their consideration of the case unless the act of Tom "Wright referred to was a reasonable act and precaution to prevent the spread of the fire wrongfully started by defendant. It is the well-recognized doctrine that in order for the act of an intelligent intervening agent, to break the sequence of events and protect the author of a primary negligence from liability such act must be an independent, superseding cause, one that the author of the primary negligence had no reasonable ground to anticipate, and usually the act must be in itself negligent, or at least culpable. In Barrows on Negligence, the position is stated and commented on as follows: “"Where an independent, efficient, wrongful cause intervenes between the original wrongful act and the injury ultimately suffered, the former, and not the latter, is deemed the proximate cause of the injury. Air efficient, intervening cause is a new proximate cause, which breaks the connection with the original cause and becomes itself solely responsible for the result in question. It must be an independent force, entirely suxrerseding the original action and rendering its effect in the chain of causation remote. It is immaterial how many new elements or forces have been introduced; if the original cause remains active, the liability for its result is not shifted. Thus where a horse is left unhitched in the street and unattended, and is maliciously -frightened by a stranger and runs away, but for the intervening act he would not have run away and the injury would not have occurred, yet it was the negligence of the driver in the first instance which made the runaway possible. This negligence has not been superseded or obliterated, and the driver is responsible for the injuries resulting. If, however, the intervening, responsible cause be of such a nature that it would be unreasonable to expect a prudent man to anticipate its happening, he will not be responsible if damage results solely from the intervention.” The same principle is satisfactorily treated in Sherman and Redford on Negligence, sec. 31 et seq., and has been very generally approved and applied in the decisions here and elsewhere. Ward v. R. R., 161 N. C., 179; Hardy v. Hines Lumber Co., 160 N. C., 113; Harvel v. Lumber Co., 154 N. C., 254; Harton v. Telephone Co., 146 N. C., 429; Harton v. Telephone Co., 141 N. C., 455; Ins. Co. v. Boon, 95 U. S., 117; R. R. v. Kellogg, 94 U. S., 469; Lane v. Atlantic Works, 111 Mass., 136.
In Harton v. Telephone Co., 141 N. C., 450, the general principle apposite is stated as follows: “The proximate cause of the event must be understood to be that which in natural and continuous sequence, unbroken by any new and independent cause, produces that event, and without which such event would not, have occurred. Proximity in point of time or space, however, is no part of the definition. The test by which *217to determine whether the intervening act of an intelligent agent which has become the efficient cause of an injury shall be considered a new and independent cause, breaking the sequence of events put in motion by the original negligence of the defendant, is whether the intervening act and the resultant injury is one that the author of the primary negligence could have reasonably foreseen and expected.”
In Hardy v. Lumber Co., Walker, J., delivering the opinion, quotes from R. R. v. Kellog, 94 U. S., at p. 475, as follows: “We do not say that even the natural and probable consequences of a wrongful act or omission are in all cases to be chargeable to the misfeasance or nonfeasance. They are not when there is a sufficient and independent cause operating between the wrong and the injury.”
In Lane v. Atlantic Works, Colt, J., delivering the opinion, states the principle: “In actions of this description, the defendant is liable for the natural and probable consequences of his negligent act or omission. The injury must be the direct result of the conduct charged, but it will not be considered too remote if, according to the usual experience of mankind, the result should have been apprehended.”
It'is well understood that when a fire of this kind is started, and under conditions importing serious menace to the principal and adjacent property, it is the custom and assuredly the right of the neighbors to lend a hand and do what reasonable prudence and judgment require to prevent its spread, and that back firing is one of the methods approved and frequently resorted to. It is also recognized that in the presence of an emergency like this the conduct of participants is'not to be considered or .judged with the critical scrutiny that may obtain in more deliberate ■circumstance. McKay v. Ry., 160 N. C., 260, and authorities cited.. In 'the present case there was much testimony tending to show that the back firing on the part of 'Wright was done in the reasonable effort to extinguish the fire wrongfully started by defendant, and with such facts in evidence, and under the principles stated, the intervening act of Wright would not break the causal connection with the original wrong of the defendant, the same being neither independent, improbable nor culpable.
Again, it is objected that a proper consideration of the record and verdict will disclose that plaintiffs, the owners in remainder, subject to the life estate of J. A. Balcum, have recovered for the entire injury done to the property when the life tenant has not been made a party and is in no way concluded by the judgment, but in our opinion this objection must also be disallowed. It is the accepted position here and elsewhere that the owners of property in remainder or reversion after a life estate may recover for a trespass which causes permanent damage to the same and to the extent that it wrongfully affects or impairs the value of their «state or interest, and this without the presence of the life tenant in the *218suit. Cherry v. Canal Co., 140 N. C., 422; Gwaltney v. Timber Co., 115 N. C., 579; Jordan v. Barwood, 42 W. Va., 312; Shortle v. Terre Haute, etc., Ry., 131 Ind., 3218.
It is further recognized and approved in several of our more recent decisions that a verdict should be “interpreted and allowed significance by a proper reference to the testimony and the charge of the court.”' Weldon v. By., at the present term; Jones v. R. R., 176 N. C., 260; Grove v. Baker, 174 N. C., 745; Reynolds v. Express Co., 172 N. C., 487.
Considering the record in view of these principles, it very clearly appears from the language of the issue, the charge of the court and his-Honor’s rulings in the exclusion of evidence, where it only tended to show injury to the life tenant, that the damages assessed in response to-the third issue have been restricted to the injuries that were permanent in their nature and to the extent that they affected the interest and estate-of the remaindermen, who are both parties of record.
On careful consideration, we find no reversible error, and the judgment on the verdict is affirmed.
No error.
