The principal exception urged for error was the refusal of the lower court to grant a motion to nonsuit. On the argument before us, it was conceded that there was evidence of negligent default and consequent injury under the Employers’ Liability Act sufficient to carry the case to the jury, and the motion to nonsuit was insisted upon on the ground that in allowing the amendment, which was done on or after 20 May (31 May), a.new cause of action was constituted, to wit, a claim under the Employers’ Liability Act, and this being more than two years after the occurrence, siich action would no longer lie.
It is expressly provided that an action under the statute will not lie after two years (Belch v. R. R., at the present term, and authorities cited), and the question will depend on whether the amendment allowed had the effect of introducing into the record and controversy a separate and distinct cause of action.
On that question, a perusal of the pleadings and facts in evidence will disclose that the injury occurred on 15 May, 1916; that action having been instituted on 16th December following, plaintiff duly filed his verified complaint, giving his version of the facts, the place and time of the occurrence, and, without definite averment, that plaintiff, when injured, was engaged in an act of interstate commerce; that on 27 February, 1917, or near that time, defendant filed his verified answer, denying the negligence and consequent injury, and alleging that the plaintiff at the time was engaged in an act of interstate commerce and the rights and liabilities of parties were controlled by the Federal Employers’ Liability Act, etc., setting up further the pleas of contributory negligence and assumption of risk as contemplated and allowed by the statute.
On issues joined, and without objection, these questions were submitted to the jury, the testimony on both sides showing that plaintiff at the time of the injury was engaged in repairing a car customarily used and to be then presently used in trains hauling interstate freight *304under the controlling decisions applicable, clearly a case of interstate commerce (N. C. R. R. v. Zachary, 232 U. S., 248, and cases cited); and the action having been conducted to that time by both parties as one, under the Emplqyers’ Liability Act, at the close of the entire evidence, plaintiff, by leave of the court, was allowed to insert the amendment making definite averment that plaintiff was injured while engaged in interstate commerce. In such case, the State court having concurrent jurisdiction of causes under Federal Employers’ Liability Act, the parties having, as stated, joined in submitting the issues appropriate to such an action, and the evidence of both sides showing that the act was applicable, we are of opinion that the omission by plaintiff to make definite averment on this question was cured by the allegations of the answer therein and the treatment of the parties concerning it, and the cause could be properly tried and determined as one under the statute without further allegation by the plaintiff. The amendment offered by him was without material significance on the record, being only a formal statement of conditions which the parties had already created and about which there was no-dispute. R. R. v. Wulf, 226 U. S., 570; Voelker v. Chicago, 116 Fed., 867.
The parties are not only concluded by their treatment of the cause as one under the Employers’ Liability Act, covered by the pleadings already filed, but the case, we think, properly calls for the application of the doctrine of “Aider” by the additional and supplemental aver-ments in the adversary pleadings by which a defective statement may be supplied, a doctrine that prevails both in the Code and common-law principles of pleading, is recognized both in Federal and State procedure and in this jurisdiction, and the better considered decisions elsewhere extends to omissions in matters of substance as well as to other defects. Whitley v. R. R., 119 N. C., 724; Knowles v. R. R., 102 N. C., 59; Garrett v. Trotter, 65 N. C., 430; Clark’s Code (3d Ed.), 232; U. S. v. Morris, 23 U. S. 10 Wheat., 246; Stack v. Lyon, 26 Mass., 62; Shively v. Water Co., 99 Cal., 259; Bliss on Code Pleading (3d Ed.), sec. 437; Pomeroy’s Remedies and Remedial Rights, sec. 579.
In Renn v. R. R., 170 N. C., 129, it was held that under our State procedure an amendment of this kind, in any event, relates back to the institution of the suit. On writ of error, this decision was affirmed by the Supreme Court of the United States (241 U. S., 290) ; and while that Court held that such an amendment might very well present a Federal question, there is nothing in the case, as we understand it, which, on the facts of the present record, forbids the disposition we make of defendant’s appeal. And in Union Pac. R. R. v. Weyler, 158 U. S., 285, a case very much relied on by defendant, plaintiff sued in a Missouri court for an injury occurring in the State of Kansas, setting forth a *305common-law action for injury by reason of an incompetent fellow-servant knowingly retained by tbe employer. After tbe lapse of sufficient time to bar recovery, botb under tbe Missouri and Kansas statutes, plaintiff amended bis pleading and declared on a statute of tbe State of Kansas (required to be pleaded) making employers liable for negligent default of fellow-servants, and it was beld'tbat sucb an amendment introduced an entirely new cause of action and tbe statute of limitations was available as a defense.
In delivering tbe opinion, Chief Justice White, tben Associate Justice, said, in effect, tbat sucb an amendment was not only a change from “fact to fact, but from law to law,” and was an entire departure from tbe cause of action as originally constituted; but in our case there is no necessity to plead tbe statute — on tbe facts as shown in evidence by botb parties, it prevails as tbe. law of tbe case (Voelker v. Chicago R. R., supra), and plaintiff, as heretofore shown, having alleged tbe circumstances of tbe occurrence, omitting definite statement as to wbetber be was at tbe time of tbe injury engaged in an act of interstate commerce, defendant answers, making full statement of tbat fact, and tbe parties, acting under sucb plea, join issue and proceed to try tbe cause under tbe statute, and we tbink tbe omission in tbe complaint is thereby cured.
Tbe case of Fleming v. R. R., 160 N. C., 196, is in no way opposed! to tbe position. In tbat case, tbe pleadings as interpreted by tbe court contained definite averment tbat plaintiff at tbe time of tbe injury was an employee on an intrastate train, and tbis being admitted, in the answer it was held tbat tbe parties were precluded from showing facts in evidence contrary to their admission, tbe ease bearing little or no resemblance to tbe facts of tbe present appeal. And Kinney v. R. R.166 N. Y. Supp., 868, and Fort Worth v. Bayard, Tex. Civ. App., 196 S. W., 597, to which we were also cited, were two causes, tbe first prosecuted through two trials as an action under tbe common law and statutes of" New York, and tbe second as an- action under a Texas statute, till after two years, when an amendment tben made setting forth for tbe first time a cause of action under Federal Employers’, Liability Act, was .held to introduce a new cause of action, barred by tbe lapse of two years, as tbat statute provides; but we find nothing in either case or record which tended to show a waiver of tbe position by tbe parties, or which called for or permitted application of tbe doctrine of “Aider,” which we have held to be tbe controlling features of tbe present appeal.
Defendant further excepted to tbe position of bis Honor’s charge as to assumption of risk, in terms as follows: “Tbat issue bears upon tbe defendant’s plea of assumption of risk. (Under tbe Federal Employers’ Liability Act, tbe common-law doctrine tbat employees assume tbe risks, dangers and hazards normally incident to tbe business, still obtains. It *306is pleaded by the defendant in this case, and the defendant has the burden of proof on that. The rule is that the employee assumes the risks normally incident to the occupation in which he voluntarily engages; other and extraordinary risks and those due to the employer’s negligence he does not assume until made aware of them, or until they become so obvious and immediately dangerous that an ordinarily prudent man would observe and appreciate them. In either or both of which cases he does assume them if he continue in the employment without objection or without obtaining from the employer an assurance that the matter will be remedied”). A definition that accords with the controlling decisions on the subject. Chesapeake and Ohio R. R. v. De-Atley, 241 U. S., 311; Gila Valley R. R. v. Hall, 232 U. S., 94. Under the principles embodied in that statement, the question was correctly and fairly submitted to the jury, and they have determined the issue against defendant.
Again, it was contended that there was error committed in his Honor’s charge on the question of damages in allowing the jury to consider the loss of mental powers when there was no evidence tending to show such loss, but the objection is not open to defendant, for, conceding that his Honor’s charge is correctly interpreted in the exception, we find abundant evidence in the record as to the effect of the injury to justify and uphold the position.
In reference to the sixth issue, as to the bar by lapse of two years, having held that plaintiff’s cause of action under the statute was covered by the original pleadings, all filed within the time (1) because the parties had elected so to treat it, and in such case a change of front is not permissible either in Federal or State procedure (Ry. v. McCarthy, 96 U. S., 258; Lindsay v. Mitchell, etc., 174 N. C., 458; Brown v. Chemical Co., 165 N. C., 421) ; (2) because the omission in the complaint to allege that plaintiff was engaged in an act of interstate commerce is aided or cured by the full averments of the answer in that respect, his Honor correctly ruled that, on the record and facts in evidence, if believed, the action was not barred by lapse of time.
On careful perusal of the record, we find no error to appellant’s prejudice, and the judgment must be affirmed.
No error.
