Appellee recovered a judgment for a personal injury sustained while in appellant’s service, on account of its alleged negligence. His complaint was in three paragraphs, and, demanding our first consideration, are the alleged errors in overruling demurrers to each of such paragraphs.
*5711. *570It is alleged in the first paragraph of the complaint that appellee entered appellant’s service as a switchman at 6 *571o’clock a. m. on October 8, 1906, and was injured in the Oliver yards at South Bend about 8:30 o’clock a. m. of that day; that appellant had in said yards four side-tracks south of the main track and connected by a “lead” track; that it became appellee’s duty to couple a loaded car, which was being moved along said lead track at the rate of two miles an hour, to a car standing on side-track number two; that the cars were equipped with automatic couplers, but the pin of the coupling on the forward end of the loaded car had been pulled from its socket, and could not be replaced by means of the lever; that it was necessary for appellee to go in front of said car and replace the pin in its socket and adjust the coupling by hand, so that the cars would couple automatically; that appellee stepped in front of the moving car for the purpose stated, and while walking along, absorbed in the work of replacing the pin and adjusting said coupling, and in the exercise of due care, the shoe on his left foot caught in a frog formed by the converging rails at the south side of side-track number two, and while trying to extricate his foot from said frog he was struck by the moving car, thrown under its wheels, run over, and thereby injured.
It is alleged that appellant knowingly, negligently and carelessly permitted the blocking in said frog to be and become so worn and rotten that only a small piece of wood about six inches in length remained, which was wholly unsuitable and inadequate to block said frog, and to keep the feet of employes from becoming fastened therein; that said piece of wood was not nailed nor fastened, but lay loose in said frog, and appellee’s foot was caught, and he was thrown and injured by reason of the fact that said frog was improperly, defectively and inadequately blocked, as aforesaid.
It is further alleged that it had been and was appellant’s custom and practice to block all frogs upon its lines, switches and side-tracks, which fact was known to ap*572pellee, and relied on by him at the time he entered appellant’s service, and was injured; that prior to his injury he had no knowledge of the defective blocking of said frog, but that appellant knew of the defective and dangerous condition of said frog in time to repair it before this accident, but negligently failed and omitted to do so.
Appellant challenges the sufficiency of this paragraph, claiming that it discloses contributory negligence, or that appellee’s injury was the result of a risk assumed by him.
Appellee avers, in general terms, that he was in the exercise of due care when injured, and the particular facts alleged do not contradict this averment. It is well settled that contributory negligence must affirmatively appear on the face of the complaint, to justify the sustaining of a demurrer thereto for such cause.
It is alleged that it was the custom and practice of appellant to block all of its frogs, which fact was known to appellee, and that he had no knowledge of the unsafe condition of the frog in question, and, relying on such custom and practice, and being absorbed in the performance of his duties, he did not discover the defect that caused his injury. These allegations were abundantly sufficient to repel any claim that the accident was the result of an assumed risk. Appellant’s objections to this paragraph are untenable, and its demurrer was correctly overruled.
2. The second paragraph contained all the allegations of the first, and further alleged that appellant negligently permitted the coupling on the forward end of the moving car to be and remain in a non-automatic, inoperative and defective condition, in that the cotter pin, which fits into the lower end of the coupling pin, and prevents it from pulling out of its socket, was lost, so that it was necessary, in order to operate said coupling, to go in front of said car and replace said coupling pin and adjust the coupling prior to each impact.
The third paragraph of complaint contained all the alie*573gations of the first, and, in addition, alleged a breach of the federal statute, making it unlawful in moving interstate traffic for an interstate carrier to permit a car to be used which is not equipped with couplers, coupling automatically by impact, and which can be uncoupled without the necessity of going between the cars. 27 Stat. p. 531.
The first paragraph having been held good, it is manifest that for the same reason, as well as other reasons, the second and third paragraphs were properly held sufficient.
3. The jury with the general verdict returned answers to a number of interrogatories, and appellant moved for judgment in its favor on the interrogatories and answers thereto, notwithstanding the general verdict. This motion was overruled and this ruling assigned as error. It is. urged in this connection that appellee was guilty of negligence in attempting, in a dangerous manner, to adjust the coupler, when he might have adopted another and safe way. This contention is not sustained by the special findings of the jury. It is specifically found that appellee, when injured, was performing his work in the manner usual and customary in appellant’s Oliver yards, and that the other way suggested, in which the coupler might have been adjusted, was “always dangerous.” The answers to interrogatories do not contradict the general verdict, and appellant’s motion for judgment was rightly overruled.
A new trial was sought on the grounds of error in giving and in refusing to give certain instructions, in the admission and rejection of certain evidence, in not requiring the jury to make fuller and more specific answers to certain interrogatories, and because the verdict is nofl*sustained by sufficient evidence and is contrary to law.
4. Instruction two is attacked because the element of assumed risk is not included. The law upon the subject of assumption of risk was fully and correctly covered in instruction five, given at the request of appellant. The *574court is not required to embody in a single instruction every legal proposition applicable to the case, but it is sufficient if the instructions as a whole correctly advise the jury upon the law.
5. Complaint is made of the giving of instructions five, eight and nine, at appellee’s request. These instructions were addressed to the question of liability for a violation of the federal statute requiring automatic couplers. The third paragraph of complaint declared upon a breach of this statute. There was evidence making the giving of such instructions proper, and taking the instructions together they accurately and fully express the law upon the proposition to which they relate.
6. The court advised the jury that if the evidence showed the existence of a general practice in appellant’s Oliver yards, at the time of, and for several years prior to this accident, of employes’ going in front of slowly-moving cars to adjust couplings, of which appellant knew, or in the exercise of ordinary care ought to have known, and in which it knowingly acquiesced, and which practice appellee knew and relied upon, it would be competent to consider such general practice in connection with other facts and circumstances in evidence in determining whether appellee was guilty of contributory negligence at the time he received his injury.
*5757. *574The instruction was unduly guarded. Its statements were more favorable to appellant than the applicable rule of law required. Appellee, in the discharge of his duties, was held to the exercise of only ordinary care, or that degree of care and watchfulness which men of ordinary prudence usually exercise for their 6wn safety in similar circumstances. The manner in which other railroad men of reasonable prudence were accustomed to adjust couplers on slowly-moving cars, provided such practice was not manifestly negligent, would fix the standard by which appellee’s conduct must be tested. This would be true even in the absence of knowledge of such *575custom by either appellant or appellee. Evidence of a practice in accord with appellee’s conduct was competent, and this instruction was relevant and proper. Pittsburgh, etc., R. Co. v. Nicholas (1906), 165 Ind. 679; Pennsylvania Co. v. McCormack (1892), 131 Ind. 250, 257; O’Mellia v. Kansas City, etc., R. Co. (1893), 115 Mo. 205, 21 S. W. 503; LaBarre v. Grand Trunk, etc., R. Co. (1903), 133 Mich. 192, 94 N. W. 735; Weed v. Chicago, etc, R. Co. (1904), 5 Neb. (Unofficial) 623, 99 N. W. 827; Louisville, etc., R. Co. v. York (1900), 128 Ala. 305, 30 South. 676; Pioneer Fire Proof, etc., Co. v. Sandberg (1900), 98 Ill. App. 36.
8. Instruction twenty, given at appellee’s request, reads as follows: “Negligence may be the proximate cause of an injury of which it is not the sole or immediate cause. If you find from the evidence that defendant was negligent in either particular alleged in the complaint, and that said negligence in that particular concurred with some other cause or causes in bringing about and causing plaintiff’s injury, the defendant’s said negligence would be a proximate cause, within the meaning of that term as used in these instructions.” Appellant contends that this instruction denied to the jury the right to determine the proximate cause of appellee’s injury. This instruction cannot fairly be so interpreted, and is not erroneous. Billman v. Indianapolis, etc., R. Co. (1881), 76 Ind. 166, 40 Am. Rep. 230; Cleveland, etc., R. Co. v. Wynant (1893), 134 Ind. 681; Board, etc., v. Mutchler (1894), 137 Ind. 140; Chicago, etc., R. Co. v. Pritchard (1907), 168 Ind. 398, 9 L. R. A. (N. S.) 857; 29 Cyc. 496, 497.
Instruction twenty-four, relating to the assessment of damages, of which appellant complains, is almost a literal copy of one approved in the case of Pittsburgh, etc., R. Co. v. Montgomery (1898), 152 Ind. 1, 26, 69 L. R. A. 875, 71 Am. St. 300.
*5769. *575The court refused appellant’s tendered instructions two and five, which were so drawn as to declare appellee guilty *576of contributory negligence, because frogs, both blocked and unblocked, were known to him to present elements of danger to a person walking in front of a moving car. Almost every act of operative railroading presents elements of known danger to the employe in such service, but this fact does not make him chargeable with negligence in undertaking such work. The question in each case is whether the particular act involved was attended with such manifest or known danger that a person of ordinary prudence should not have attempted its performance under existing circumstances. The proffered instructions were properly refused, and the question whether appellee was guilty of contributory negligence in this case was not one of law for the court, but one of fact for the determination of the jury, in the light of all the evidence, and the instructions of the court upon that subject.
10. Appellant’s instructions seven and eight related to its duty to inspect foreign cars. These instructions might have been relevant and proper in a common-law action, based on a defect in a foreign car, but the paragraphs of appellee’s complaint involving the defective coupling • on a foreign car were founded on the specific provisions of state and federal statutes, imposing upon appellant an imperative duty to use no car, regardless of ownership, unless equipped with automatic couplers in normal working condition. The tendered instructions were clearly irrelevant.
11. Instruction nine, requested by appellant, sought to charge that the defect in the coupler shown in this case was not such as reasonably to give appellant notice of danger to appellee in the performance of his duties, and that no recovery based on such defect could be had. In the most favorable view to be taken of the proposition advanced, the question was not one of law, but was properly submitted to the jury for decision, and this instruction was rightly refused.
*57712. *576Appellant’s instruction ten declared there was no evidence *577to charge it with knowledge of the absence of the cotter pin, and hence no proof of negligence in failing to make proper repairs. The showing of a defective coupler in use in violation of statutory requirements constituted a prima facie case of negligence, and if the exercise of any degree of care would excuse the use of the coupler without such pin — a question we are not called upon to decide — the burden of showing the extenuating facts rested on appellant. This instruction proceeded upon an erroneous theory, and was properly refused.
13. Instructions eleven to twenty-one, inclusive, and twenty-four, tendered by appellant, purported to state the law with regard to the choice of an unsafe way to do work, when a known safe way was equally available. A consideration of these instructions is unnecessary, in view of the special finding of the jury, that the suggested safe ways were “always dangerous.” Pittsburgh, etc., R. Co. v. Collins (1907), 168 Ind. 467; New Castle Bridge Co. v. Doty (1907), 168 Ind. 259; City of Muncie v. Hey (1905), 164 Ind. 570; Baltimore, etc., R. Co. v. Harbin (1903), 160 Ind. 441; Roush v. Roush (1900), 154 Ind. 562.
14. Instruction twenty-five, tendered and refused, declared, as a matter of law, that the car in question was equipped with an automatic coupler, in accordance with the requirements of the federal statute. It was shown, without dispute, that the coupler would not couple by impact, without previous adjustment by hand. This condition was not in accord with the manifest purpose and requirements of the law, and the instruction was erroneous.
15. Appellee, as a witness, was asked whether before receiving his injury, and on the same morning, appellant’s foreman and yardmaster, Kellogg, instructed him with reference to going in front of moving cars, or going between moving cars to adjust defective couplers, and he answered in the affirmative. He was then asked to relate *578what Kellogg said to him on this subject. Appellant’s objection to the question was overruled. Appellee’s insistence is that he was adjusting the coupler, in conformity with instructions, at the time he was injured. He had entered upon his duties as switchman but two hours before he was injured, and it was certainly competent for either party to prove what, if any, instructions had been given him touching the manner of performing the duties assigned to him. The objection was correctly overruled. Indiana Car Co. v. Parker (1885), 100 Ind. 181, 198; Rogers v. Overton (1882), 87 Ind. 410.
16. The jury in answer to an interrogatory found that after opening the switch to track number two, appellee could have signaled the engineer to stop, and after the engine and cars had stopped he could have gone in front of the car in question and replaced the pin in the coupler.
*57917. *578The jury was asked in various forms whether this could have been done by appellee with safety to himself, and the answer in every instance was, “Always dangerous.” Appellant requested the court to require the jury to answer specifically “Yes” or “No,” but its request was denied, and complaint is made of this ruling. The jury found that the engineer in charge of the engine at the time of the accident, in distributing cars about the yards, was controlled and directed as to the movements of the engine by signals from appellee, and also by signals from Kellogg, the yardmaster. It was further shown that said yardmaster was present at the time of the accident, giving signals concurrently with appellee. The answer of the jury is responsive to the questions propounded, and is equivalent to a simple “No.” The query was, Could appellee have done the suggested act with safety to himself? and the response was, “Always dangerous.” The clear meaning of such answer was, “Not with safety to himself,” or “No.” If the interrogatory had been made sufficiently comprehensive to.insure the engine’s remaining *579stationary while the coupler was being adjusted, a different answer would have seemed proper, but under the circumstances shown, the thought in the minds of the jurors doubtless was that the engine was liable to move at the signal of the yardmaster, at any moment, making it dangerous to go in front of the cars to which it was attached. Interrogatories should ordinarily be so framed as to admit of a direct answer of “Yes” or “No;” but we cannot say that the court committed harmful error in refusing to require such answers to the interrogatories under consideration. Fort Wayne Cooperage Co. v. Page (1908), 170 Ind. 585; Salem-Bedford Stone Co. v. Hilt (1901), 26 Ind. App. 543.
18. The legality of the verdict is challenged on the ground that it is not sustained by sufficient evidence. Appellant insists that appellee was guilty of contributory negligence in trying to adjust the coupler on the front of a moving car, when it was approaching a frog and other obstructions known to him to be in the track. Cases are cited in which the court held the injured party negligent as a matter of law, but they are readily distinguishable from this one. In some of them a rule of the company prohibited an employe from going in front of a moving car in the performance of his duties, and this rule was violated without the knowledge or consent of the company; and in other cases the complaining employe had exclusive control of the movements of the engine, and voluntarily undertook to do his work in an unusual and manifestly dangerous way, when he could have pursued a known practical and safe way. Appellee’s conduct in this case must be viewed and judged in connection with appellant’s alleged negligence. Appellant had undertaken to block all the frogs in its yards, and appellee knew and relied upon this fact. A blocked frog may not be wholly free from danger, but we cannot say that this accident would have happened as it did if the blocking had been properly done, or had been in good condition. The evidence showed that *580the blocking was rotten and in bad condition, and that, because of its apparent security, it was likely to be more dangerous than it would have been had it been known to be wholly unblocked. The engineer was not subject to the exclusive control and direction of appellee. In view of all the attendant facts and circumstances, the question of contributory negligence was rightly submitted to the jury for determination, and we cannot say that its conclusion was not warranted by the evidence.
The motion for a new trial was correctly overruled, and the judgment is affirmed.
