It was chiefly objected to the validity of the trial that his Honor refused to hold as a matter of law that plaintiff was barred of recovery by reason of assumption of risk — this on the ground, first, that the making of a flying switch was one of the ordinary incidents of plaintiff’s employment; second, that the engineer engaged in making such switch -was a fellow-servant, and, on the facts in evidence, his negligence, if it. shoidd be established, should be properly classed as one of the assumed risks in the course of plaintiff’s employment; but in our opinion neither position can be maintained. The first is closed to defendant by reason of the finding of the jury on the first issue. It is the accepted principle in our procedure that a verdict must be interpreted and allowed significance by proper reference to the testimony and the charge of the court. Reynolds v. Express Co., 172 N. C., 487; Donnell v. Greensboro, 164 N. C., 330.
In the present case, while the complaint seems to specify the “making of the flying switch as a separate act of negligence, a perusal of the evi-*264deuce and the charge of the court will disclose that the making of the switch itself was not allowed as a ground of liability, but that the considerations and decisions of the first issue was restricted to the question whether there was negligence in making such switch by bringing the engine to an unnecessary and unusual stop,” the language of his Honor’s direct charge on the first issue being as follows:
“If you should find from the evidence, and by the greater weight of the evidence, that the engineer suddenly, by use of air brakes or any other appliance, suddenly and unnecessarily checked the speed of the engine in such a manner as to cause an unusual and unnecessary jar, sufficient to throw the plaintiff from the car, and he was thrown by reason of that from the car and run over and hurt, you will answer the first issue ‘Yes’; but if you fail to so find, you will answer it No.’ ”
The verdict on the first issue, therefore, having eliminated “the making of a flying switch as a ground of liability,” that fact as a separate circumstance is withdrawn from consideration also on the question of assumption of risk. And this, too, is the final answer to the second ground of defendant’s objection; though, as argued, this presents other questions that it may be well to consider. At common law, or under the later decisions of the common-law courts, the negligence of a fellow-servant was classed among the risks assumed by an employee engaged in a common service, and on the facts of this record the engineer and brakeman are undoubtedly fellow-servants within the meaning of the principle. New England R. R. v. Conroy, 175 U. S., 323; B. & O. Ry. v. Baugh, 149 U. S., 369.
This cause, however, coming under the Federal Employer’s Liability Act, it is fully established that the statute itself affords the exclusive and controlling rule of liability, and the question presented must be determined in accord with its provisions applicable and authoritative Federal decisions construing them. Belch v. Seaboard Air Line, at the present term, citing Erie R. R. v. Winfield, 244 U. S., 170; N. Y. Central v. Winfield, 244 U. S., 147; St. Louis, &c., R. R. v. Hesterly, Admr., 228 U. S., 702; Second Employer’s Liability Cases, 223 U. S., 1.
"While the law in question clearly recognizes assumption of risk as a defense in certain instances, under section 4 such a position is absolutely inhibited in cases where the violation of a Federal statute, enacted for the protection of the employees, contributed to the injury or death of employee; and by correct deduction from the terms and meaning of section 1, making railroads engaged as common carriers of interstate commerce liable in damages for injuries or death caused by the negligence of their officers, agents, or employees, the negligence of fellow-servants is withdrawn from the class of assumed risks in cases of unusual and instant negligence and under circumstances which afforded the injured *265employee no opportunity to know of the conditions or appreciate the attendant dangers. This doctrine of assumption of risk is based upon knowledge or a fair and reasonable opportunity to know, and usually this knowledge and opportunity must “come in time to be of use.” 26 Cyc., p. 1202, citing 160 Ind., p. 583. This principle is very generally approved in the cases and text-books on the subject; and in authoritative Federal decisions construing the act in question, in reference to the negligence of fellow-servants and the incidental assumption of risks, it has been held that the effect of this first section is to place the conduct of fellow-servants on the same plane as the employer himself in such cases, and it is fully recognized that an employee does not assume the risks of his employer’s negligence unless, as stated, he is given a fair opportunity to know and appreciate the risks to which he is thereby subjected. Chesapeake & Ohio Ry. v. De Atly, 241 U. S., 311; Yazoo, &c., Ry. v. Wright, 234 U. S., 376; Seaboard Air Line v. Horton, 233 U. S., 492; Gila Valley, &c., Ry. v. Hall, 232 U. S., 94; Texas & Pacific Ry. v. Behymer, 189 U. S., 905; 2 Employer’s Liability Cases, 223 U. S., 1; Grybowski v. Erie R. Co., 88 N. J. L., 1 (95 At., 764) ; Richey on Fed. Emp. Liability Act, sec. 59. In Gila Valley Ry. v. Hall the general position,is stated as follows:
“An employee assumes the risk of dangers normally incident to the occupation in which he voluntarily engages, so far as they are not attributable to the employer’s negligence; but the employee has the right to assume that his employer has exercised proper care with respect to providing safe appliances for the work, and is not to be treated as assuming the risk arising from a defect that is attributable to the employer’s negligence until the employee becomes aware of such defect, or unless it is so plainly observable that he may be presumed to have known of it.
“In order to charge an employee with the assumption of a risk attributable to a defect due to the employer’s negligence, it must appear not only that he knew (or is presumed to have known) of the defect, but that he knew that it endangered his safety; or else such danger must have been so obvious that an ordinarily prudent person under the circumstances would have appreciated it.”
In Chesapeake & Ohio Ry. v. Atley, where an employee was injured in the endeavor to board a moving train in the course of his employment, and was injured by the unusual speed of the engine, it was held as follows :
“The Employer’s Liability Act abrogated the common-law fellow-servant rule by placing negligence of a coemployee upon the same basis as negligence of the employer.
“In saving the defense of assumption of risk in cases other than those where the carrier’s violation of a statute enacted for the safety of em*266ployees contributed to tbe injury or death, the Employer’s Liability Act places a coemployee’s negligence, where it is the ground of the action, in the same relation as the employer’s own negligence would stand to the question whether a plaintiff is to be deemed to have assumed the risk.
“A railroad employee, having voluntarily entered an employment requiring him on proper occasions to board a moving train, assumes the-risk normally incident thereto, other than such risk as may arise from the failure of the engineer to use due care to operate the train at a moderate rate of speed, so as to enable his coemployee to board it without undue peril.
“Such an employee may presume the engineer will exercise due care-for his safety, and does not assume the risk attributable to operation at unduly high speed until made aware of danger, unless the undue speed and consequent danger are so obvious that an ordinarily careful person in his situation would observe the speed and appreciate the danger.
“An employee is not bound to exercise care to discover extraordinary dangers arising from the negligence of the employer or of those for whose conduct the employer is responsible, but may assume that the employer or his agents have exercised proper care with respect to his-safety until notified to the contrary, unless the want of care mid the danger are so obvious that an ordinarily careful person, under the circumstances, would observe and appreciate them.”
It will be noted that this was an action under the Employers’ Liability Statute and bears with much directness on the facts of the present case. And Yazoo, etc., Ry. v. Wright was also a case under the Employers’' Liability Act and holding that no case of assumption of risk was presented when an employee was injured by negligence of the master or-fellow-servant and the circumstances gave no opportunity to know the-danger “in time to be of use.”
In Ry. v. Behmyer, supra, a case where an employee had recovered for injuries attributable to an unusual and sudden jerking of a freight train, Associate Justice Ilolmes, delivering the opinion in affirmance of' the judgment below, said: “No doubt a certain amount of bumping- and jerking is to be expected on freight trains, and, under ordinary circumstances, cannot be complained of, yet it can be avoided if necessary, and when the particular and known conditions of the train makes a sudden bump obviously dangerous to those known to be on the top of' the cars, we are not prepared to say that a jury would not be warranted in finding that an easy stop is a duty. If it was negligent to stop as it did stop, the risk of it was,not assumed by plaintiff.” Citing Tex. Pac. Ry. v. Archibald, 170 U. S., 665-672.
The case Boldt v. Ry., 245 U. S., 442, a decision very much relied on by defendant, does not antagonize the position approved and applied in *267the cases cited. In Boldtfs case, “The intestate of plaintiff, while between cars in a freight yard helping to repair a faulty coupler, was killed by the impact of a string of cars moving by gravity under the control of a brakeman. It was contended that the brakeman negligently permitted the moving cars to strike with too great violence, and that the company failed to promulgate adequate rules on the subject, with evidence to support both claims.” There was also evidence tending to show that it was usual to allow the moving cars to strike others that were stationary with force sufficient to make the coupling, etc. On the trial below there was verdict for the company, and on writ of error by plaintiff the single exception insisted on was the refusal of the trial court to give the following instruction asked by him: “The risk the employee now assumes since the passing of the Federal Employers’ Liability Act is the ordinary dangers incident to his employment which does not now include the assumption of risks incident to the negligence of the owner’s officers, agents and employees.”
In overruling the exceptions, the Court, adhering to its former position that the act had the effect of placing the negligence of a fellow-servant in the same category as that of the employer’s, held that the prayer for instruction was too broadly stated, as the employee, as a rule, assumed the “extraordinary risks caused by the master’s negligence where they are obvious or fully known and appreciated by him”; but, as will be readily seen, the case gives no support to the position that the employee assumes the risks incident to an act of negligence by the employer or fellow-servant where no opportunity was afforded to know or appreciate the conditions or its attendant dangers.
This being, in our opinion, the correct principles applicable, and the jury, under the charge of the court, having, as stated, established by their verdict on the first and second issues that plaintiff was thrown from the car and run over and injured solely by reason of the sudden, unusual and unnecessary manner in which the engine and car were stopped by the engineer, an instant act of negligence on his part, we think defendant’s motion was properly disallowed and his Honor correctly ruled that, on the facts so established, the defense of assumption of risk was not available to defendant.
It. was further objected that his Honor gave an erroneous definition of assumption of risk. The court charged the jury that if the company was accustomed to make these flying switches and plaintiff to assist in them, he assumed the risk of the incidental dangers, and his general definition of the principle seems to be in accord with the decisions on the subject. But having restricted the fact of liability on the first issue to the single question whether the engineer made the flying switch negligently by bringing his engine to an unnecessary and unusual and sud*268den stop, and this having been determined in plaintiff’s favor, the court, under the authorities, was justified in the ruling that there could be no assumption of risk, and his definition was without appreciable significance, and should not be allowed to affect the result.
It was further insisted that his Honor committed prejudicial' error in his charge on the question of damages by saying, in certain aspects, the plaintiff should recover the “full measure of damages,” but this exception is without merit. It was used in connection with his Honor’s instructions in reference to the effect of plaintiff’s contributory negligence on the amount of damages. Having charged that the damages must be proportionately reduced in case there was contributory negligence on part of plaintiff, he used the term “full measure” to express correctly the rule of adjustment in case there was no negligent default on plaintiff’s part; and it has been held that the term in any event does not always constitute reversible error. Texas Ry. v. McCarty, 49 Tex. Civ. App., 532.
Defendant excepted further to the rulings of the court on questions of evidence. First, that his Honor allowed plaintiff to put in evidence a separate clause of section 5 of the answer as follows: “That in order to disconnect the said moving engine and car, it was necessary, as- a part of said operation, to apply air to the engine so as to slow the same down.” And further, that he l’efused to permit defendant to introduce other portions of said answer materially affecting said admissions.
In this connection, his Honor offered to allow defendant, in reply, to introduce*the accompanying statements of this paragraph as follows:' “That, pursuant to said purpose, the said engine and cars were proceeding along the track and in the usual and customary manner, and the said engine was slowed down and the car uncoupled from said engine.” The defendant declined, and in addition offered in evidence the entire remaining portion of the paragraph and excepted to the ruling excluding the additional statement.
It is the settled rule of procedure in this jurisdiction that a party may offer in evidence a portion of his adversary’s pleadings containing an allegation or admission of a distinct and separate fact relevant to the inquiry and without introducing qualifying or explanatory matter, the rule being further to the effect that in such case it is open to the opposing party to introduce such qualifying matter if he so desires. Wade v. Contracting Co., 149 N. C., 177; Sawyer v. R. R., 145 N. C., 24; Lewis v. R. R., 132 N. C., 382.
A correct application of the principle is in full support of his Honor’s ruling on both questions. . The part of paragraph 5 admitted was of a distinct and separate fact relevant to the issue. His Honor offered to allow defendant to introduce in reply any accompanying allegation *269wbicb could properly be said to qualify or explain tbe fact, and tbe additional allegations of tbe answer insisted on by appellant averring contributory negligence by plaintiff were in no sense qualifying or explanatory of tbe fact admitted,, and were therefore properly excluded.
It was contended further for error that tbe court, over tbe defendant’s objection, allowed in evidence tbe testimony of tbe witness S. C. Green, a locomotive engineer, as to tbe customary and proper manner of making these flying switches and tbe use of tbe appliances on tbe engine provided for tbe purpose.
On tbe argument before us, tbe objection was urged chiefly on tbe ground that there bad been no preliminary finding by tbe court that tbe witness was an expert, but no such objection was made on tbe trial, nor was the court asked or required to make a finding on tbe preliminary question. Tbe record shows that there was only a general objection to tbe evidence of tbe witness; and this being true, assuming that tbe testimony of tbe witness was opinion evidence and tbe record showing that tbe witness was fully qualified as an expert, tbe presumption is either that there was a preliminary finding by tbe court or that tbe same bad been waived. Lumber Co. v. R. R., 151 N. C., 217-220, citing Britt v. R. R., 148 N. C., 37; Summerlin v. R. R., 133 N. C., 550.
Apart from this, and under our decisions, tbe witness being, as tbe record' shows, qualified by training and experience to express an opinion calculated to aid tbe jury to a correct conclusion, and speaking to tbe operation and use of engines and appliances exactly similar in structure and operation to that used in tbe instant case, bis estimates and statement of tbe correct use of such appliances were facts relevant to tbe issue and properly received in evidence whether in strictness expert evidence or not. Tire Setter Co. v. Whitehurst, 148 N. C., 446; Britt v. R. R., 148 N. C., 37.
There were other exceptions noted, but while they have all been duly considered, being without appreciable bearing, or significance on tbe ■results of tbe trial, they are not further adverted to.
"We find no error in tbe record and tbe judgment for plaintiff is affirmed.
No error.
