A rehearing has been granted, and the case reargued, and again submitted. The first and second divisions of our former opinion, ante, p. 387, are not assailed. We have considered further the questions of assumed risk and contributory negligence in the light of additional adjudications called to our attention by appellant’s able counsel. Did the fatal accident fall within the usual hazards of the business in which Grimm was engaged? We confess that the case is not free from difficulty, and that the question involved is a close one. On first impression, one is inclined to think that deceased assumed the risk and that his administratrix cannot recover; but, upon mature reflection, the view taken by the learned trial court seems more just and reasonable, and leads one to conclude, whatever may be his views if acting as a trier of fact, that there is a reasonable probability of different minds reaching different conclusions on the question of assumed risk, and hence its determination should be left, where the district court placed it, with the jury. At any *396rate, we must presume that the lower court’s ruling was correct, until the contrary is established.
There is another presumption which must be given weight. The record is silent as to the conduct of the deceased from the time he left the defendant’s place of business until he arrived at Selby’s residence, where the accident occurred. “The instinct of self-preservation and the disposition of men to avoid personal harm reinforce an inference that a person killed or injured was in the exercise of ordinary care.” 16 Cyc. 1057, note 49; Baltimore & P. R. Co. v. Landrigan, 191 U. S. 461; Kansas City-Leavenworth R. Co. v. Gallagher, 68 Kan. 424, 64 L. R. A. 344; Hendrickson v. Great Northern R. Co., 49 Minn. 245; Northern P. R. Co. v. Spike, 121 Fed. 44. In the case last cited, Caldwell, Circuit Judge, said: “The presumption arising from this natural instinct of self-preservation stands in the place of positive evidence, and is sufficient to warrant a recovery, in the absence of countervailing testimony. * * * Nor is this presumption applied only when no one witnesses the accident. It has its application in all cases, and may be strong enough to overcome the testimony of an eye-witness. * * * This principle has been repeatedly affirmed and applied by the supreme court of the United States.”
Another inquiry is: Upon whom is the burden of proving that Grimm assumed the risk of the a'ccident which resulted in his death? We think the weight of authority is that the burden of sustaining this defense is upon the defendant. Dowd v. New York, O. & W. R. Co., 170 N. Y. 459; Calloway v. Agar Packing Co., 129 Ia. 1; Arenschield v. Chicago, R. I. & P. R. Co., 128 Ia. 677; Mace v. Boedker & Co., 127 Ia. 721; Nadau v. White River Lumber Co., 76 Wis. 120; Norfolk & W. R. Co. v. Ward, 90 Va. 687, 19 S. E. 849; Missouri, K. & T. R. Co. v. Jones, 35 Tex. Civ. App. 584, 80 S. W. 852; McDonald v. Champion Iron & Steel Co., 140 Mich. 401; Judd v. Chesapeake & O. R. Co., 18 Ky. Law Rep. 747, 37 S. W. 842; Jackson Lumber Co. v. Cunningham, 141 Ala. 206, 37 So. 445.
*397In view of the rules above stated and the general principles announced in the former opinion, can it be said that deceased must be held as a matter of law to have assumed the risk of the injury which caused his death? Grimm was “a first-class lineman,” who had been in defendant’s employ for a year and a half. Defendant, however, contends that he was “a trouble finder,” that his employment required the performance of dangerous duties, and that the risks which he assumed were commensurate with his extra-hazardous employment. In defendant’s brief it is said: “James 0. Grimm, a lineman and trouble-man of large experience, familiar with the work and the dangers of his employment, was selected for this particular service of inspecting and repairing the defective and dangerous conditions referred to.” The only evidence in support of this contention is the testimony of defendant’s foreman, who said that Grimm was a lineman receiving $2.85 a day; that $2.85 was the standard wage (for lineman, we suppose); that he usually earned a little more salary than others working in the same capacity, because he worked a great deal over time. “He was'a man whom I would take for over-time work, taking care of trouble or anything that might come up after the ordinary hours, and in that way nsed. We usually have trouble after a storm. * * * Q. What sort of trouble? A. From various causes. The wires become deranged after a wind, and, so, many things have a great deal to do with causing trouble. Wires come in contact with poles and wood, and so on, that might cause any burning of high potential wires. Q. State whether you have cases -where wires of different potentiality come in contact? A. That occurs at times; yes, sir. Q. So all of these conditions occur from time to time? A. They do. Q. In the life of an electric light man, you say? A. Yes, sir. Q. State what the fitness or competency of Mr. Grimm was with respect to that class of work. A. I considered him a first-class man.” If the above evidence is sufficient to establish, to such a degree of certainty that all reasonable minds are con*398vinced, that Grimm was employed for the purpose of finding and repairing dangerous defects of an extra-hazardous nature, and that his experience or knowledge was such that he kneAV or should have knoAvn the probable results of his conduct at the time of his death, then the defendant Avas justified in sending him out upon this hazardous service, and Grimm assumed the risk incident thereto. Defects, such as caused Grimm’s death, it appears from the evidence quoted, occur from time to time during the life of an electric light man. From this it Avould seem improbable that the deceased, a man 23 years of age, had by experience acquired a great deal of knowledge regarding defects of the kind testified to. It does not appear that he received extra Avages for extra-hazardous sendee, nor does it appear that he had been engaged in extra-hazardous work. At most, he was used for over-time Avork taking care of trouble. The nature of the trouble referred to by the witness is not knoAvn, but' a reasonable inference, in the absence of an explanation, and in view of the fact that Grimm was receiving a lineman’s wages, is that it referred to common-place troubles, and not. such as are extra-hazardous and dangerous to human life. The administratrix testified that her husband (Grimm) was “a lineman.” The jury, under all the circumstances of the case, were not compelled to find that deceased was an inspector or trouble finder.
However, if plaintiff’s decedent knew that the wires on Forty-Ninth street were in contact, and with this knowledge attempted to turn on the light in Selby’s residence, we can see how it could be held that he assumed the risk. The question of the assumption of risk generally turns upon the actual or constructive knoAvledge of the deceased of the dangers at the time of the injury. “The doctrine of the assumption of risk is wholly dependent upon the servant’s knowledge, actual or constructive, of the dangers incident to his employment. Where he knows, or in the exercise of reasonable and ordinary care should, know, the risks to which he is exposed, he will, as a rule, be held to *399have assumed them; but Avhere he either does not knoAv, or, knowing, does not appreciate, such risks, and his ignorance or nonappreciation is hot due to negligence or AArant of due care on his part, there is no assumption of risk on the part of the servant preventing a recovery for injuries.” 26 Cyc. T196-1199, and many cases there cited.
Noav, the burden of proving that Grimm had knoAvledge, or should have knoAvn, of the risks to which he was exposed, rested upon the defendant company. There is no proof, and the record is silent, as to the conduct of the deceased immediately prior to his appearance at the Selby residence on the morning in question. If we take as true the foreman’s version of the conversation that he informed deceased that the disturbance Avas due to crossed wires on Forty-Ninth street, still the record does not disclose AAdiat examination Grimm made of the wires along Forty-Ninth street to discover a cross before proceeding to Selby’s residence. The city electrician, a man of considerable experience, made an examination of the Avires along Forty-Ninth street after Grimm was killed, and testified that he could barely see the crossed Avires among the branches of the trees. For all that the evidence discloses, Grimm may have made an examination of the wires on Forty-Ninth street, and failed, in the exercise of due care, to discoArer the crossed Avires, Avhich could barely be seen among the branches of the trees. If Grimm had been informed of the contact of the Avires, he certainly had the highest motives for making such an examination, for his life depended upon such caution being taken. The company did not prove that he failed to make such an examination, or was aware of the crossed wires, or did not use ordinary care to discover them. In view of the natural instinct of self-preservation and the disposition of men to avoid personal harm, the jury were justified in presuming that plaintiff’s intestate Avas in the exercise of ordinary care, and had made a prudent examination of the Avires on Forty-Ninth street, and failed to discover the Avires in contact among the branches of the trees. If this *400is true, then deceased did not know that Selby’s incandescent lamp was charged with the deadly current of 2,300 volts of electricity. “In the absence of evidence conclusively establishing assumption by a servant of the risk of his employment, the fact that the servant did not establish affirmatively that he had no knowledge of the risk, and therefore did not waive it, will not prevent a finding that he was not chargeable with knowledge.” Dowd v. New York, O. & W. R. Co., 63 N. E. 541 (170 N. Y. 459).
Another view of the evidence, one very unfavorable to defendant, may.be reasonably taken. Defendant’s foreman testified, as stated in our former opinion, that he told Grimm “that in all probability there was a cross between the primary and secondary wires on Forty-Ninth-street, that he should look carefully along Forty-Ninth street as the trees were pretty thick there, and that the trouble in all probability would be found at that point.” No living person can either corroborate or refute the foreman’s testimony as to this conversation. If, as this witness testified, he knew that the high and low potential wires were in contact, ordinary prudence would dictate that he should have informed not only Grimm, but, further, that he should have warned the Selby family, or immediately cut off the death dealing current, not necessarily for the protection of Grimm, but for the protection of the company’s patrons and the public generally. It would not be an unreasonable inference for the jury to draw from the evidence that defendant’s foreman never instructed Grimm as he said he did, but sent him forth on his fatal mission without warning, and to deal with dangers he never assumed. Morrison, an electrician with greater experience than Grimm, was fully conversant with all the facts communicated to defendant by the Selbys, and not until Grimm’s death did he think that the disturbance was caused by contact of the high and low potential wires. We also have the testimony of Mr. Michaelson, a fair witness, and an experienced electrician, to the effect that knowledge of the shock to the Selby boy would not indi*401cate to an electrician that the lamp where the shock was received was extra dangerous, but quite the contrary, as the boy survived. How the facts known and communicated by Mr. Selby would indicate to the defendant’s foreman that there was contact of high and low potential wires,-and thereby give him occasion to communicate such facts to Grimm, was undoubtedly not explained to the satisfaction of the jury, and has not been explained to our satisfaction. In our former opinion, we erred in reciting this conversation as an established fact in the case, but this was not prejudicial to the defendant.
Our attention is called to cases which, it is claimed, are in conflict with the conclusion we have reached. The principal authority cited is Bell Telephone Co. v. Detharding, 148 Fed. 371, wherein it was held: “Plaintiff’s intestate was employed by defendant telephone company as a ‘trouble finder,’ and was sent by his superior, in the line of his duty, to ascertain the cause of the failure of a telephone to work properly, -which was unknown. In climbing a cable pole his hand came in contact with a guy wire, from which he received an electric shock, which caused him to fall, and he was killed. From the effects of a storm on the previous night, or from some other cause not shown, the telephone wires leading from the pole had sagged across electric light wires, and had become heavily charged with electricity, and also charged the guy wire. Held, That the risk from such danger was one known to and assumed by plaintiff’s intestate as one necessarily incidental to his employment, and that there could he no •recovery from the defendant for his death.” This case, at first thought, would seem decisive of the one in hand; but, when we bear in mind that in the case cited there was, as expressly stated by the court, no “lack of diligence on the part of the defendant below shown,” and apply the rule established in this state that “a servant generally does not assume the risk of dangers due to his master’s negligence” (Chicago, R. I. & P. R. Co. v. McCarty, 49 Neb. *402475), we are constrained to hold that plaintiff’s intestate did not, as a matter of law, assume the risk due to defendant’s negligent construction of its electric wires. See Belvidere G. & E. Co. v. Boyer, 122 Ill. App. 116; Chicago, S. W. & L. Co. v. Hyslop, 227 Ill. 308.
We now come to the other question presented for further discussion. It is unnecessary here to repeat what was said in the fourth division of our former opinion. Additional authorities have been cited, and examined, and are found not to require the overruling of our former pronouncement on the question of contributory negligence. This case is clearly distinguishable from cases like Citizens Telephone Co. v. Westcott, 99 S. W. (Ky.) 1153, and Johnston v. New Omaha T.-H. E. L. Co., 78 Neb. 27, and must be classed with those like Predmore v. Consumers L. & P. Co., 99 App. Div. (N. Y.), 551, and Belvidere G. & E. Co. v. Boyer, supra. In the first class the courts held, for obvious reasons, that the injured party knew of, and deliberately placed himself in, a position to receive an electric shock, and hence could not recover. In the latter class experienced electricians knew that others had received shocks from electric fixtures not resulting fatally, and after knowing the effect of contact therewith attempted to adjust the difficulty, and were killed. Such circumstances do not so clearly establish contributory negligence as to remove the question into the realm of undebatable fact and require a peremptory instruction to the jury. See authorities cited in former opinion.
In Belvidere G. & E. Co. v. Boyer, supra, the company was engaged in running an electric plant in the city of Belvidere. Deceased, a man of considerable experience with electric machinery, was its engineer and had charge of the building and the machinery and the men employed therein, and, when repairs were to be made in the room, he made them or saw that they were made. Another employee, one Tynan, received a shock from a wire on which a light was suspended. The shock rendered him unconscious for a time. Deceased said he would taire the wire *403down so no one else would get hurt. He was warned by the employee who had received the shock, but went into the room where the light was, and the only eye-witness to the accident says he saw him attempt to take down the extension, and it seemed to draw him right up. He was reaching for the plug — he knew enough not to take hold of the wire — but he was' killed. The wire was intended for and usually carried but 110 volts. Unknown to deceased the wire had come in contact outside of the building with another wire carrying 1,100 volts. In the opinion the court said: “While the proof shows men had received shocks from the wire that caused Boyer’s death two or three days before his death occurred, and that Boyer knew of this, it further shows the shocks were not of a serious nature before the one received by Tynan, and, further, that the conditions which caused these shocks to the men Avere not known to any one whose employment was inside the building until after Boyer’s death. The fact that persons handling the Avire received slight shocks might indicate that the insulation on the wires Avas worn and defective without apprising one of the fact that they had come in contact with a wire outside, which was carrying a powerful current.” The court left the determination of the question of contributory negligence to the jury, and said in the syllabus: “In determining whether one Avho has lost his life by an accident has been guilty of contributory negligence, it is only proper to consider his acts in connection with conditions as they appeared and were known at the time of the accident, and conditions not known to exist until after his death should be rejected.” See, also, Chicago, S. W. & L. Co. v. Hyslop, supra.
While the questions presented by the record before us are not free from difficulty, we think the facts are such that reasonable men would differ as to the proper inference to be drawn. This being true, the district court was not in error in submitting the case to the jury.
We therefore recommend that our former judgment of affirmance be adhered to.
Duffie and Good, GO., concur.*404By the Court: For the reasons stated in the foregoing opinion, the judgment of affirmance heretofore entered is adhered to.
Affirmed.
