It is rightly contended by appellant’s counsel, and conceded by counsel for respondent, that unless as a matter of law, on the evidence, the engineer stood towards the respondent in the master’s place, charged with its duty to furnish him a reasonably safe place in which to perform his work, as regards the guarding of the lubricator glass, and there was reasonable ground on the evidence for the finding that he submitted himself to the risk which resulted in his injury upon the faith of the engineer’s promise to perform that duty, and was not guilty of any want of ordinary •care in so doing, the judgment is wrong. The jury did not find whether the engineer and respondent were fellow-servants in respect to the matter stated. Perhaps no finding was necessary. Probably it should be said that the evidence bearing on the subject is undisputed and that the inferences that may reasonably be drawn therefrom are not conflict*538ing. Yet, just how the learned court reached the conclusion that the relation existed, requisite to charge defendant with the engineer’s promise, does not clearly appear.
Generally speaking, all trainmen, from engineer, to the humblest employee, are fellow-servants and only such. Howland v. M., L. S. & W. R. Co. 54 Wis. 226; Heine v. C. & N. W. R. Co. 58 Wis. 528; Fowler v. C. & N. W. R. Co. 61 Wis. 159; Pease v. C. & N. W. R. Co. 61 Wis. 163; Southern Fla. R. Co. v. Price, 32 Fla. 46; Ohio & M. R. Co. v. Tindall, 13 Ind. 366; Clifford v. O. C. R. Co. 141 Mass. 564; Elliott, R. R. § 1330. To take the situation in question out of that general rule requires evidence to the effect that the furnishing of the guard for the lubricator glass was not only the duty of the master — a duty distinct from those minor details of business which may be left to servants, as such, to attend to — but that the master intrusted such duty to the engineer. AVhere the evidence is to that effect, as before indicated, does not clearly appear. It may be that the idea of the trial judge was that since the engineer was superior in grade of service to his fireman, the relation of master and servant existed between them. Rut that is not the test, as. is abundantly shown by the adjudications of this court above cited. Mere rank has nothing to do with the question. The test is the nature of the act in which the persons are engaged. Cadden v. Am. S. B. Co. 88 Wis. 409; Dwyer v. Am. Exp. Co. 82 Wis. 307; McMahon v. Ida M. Co. 95 Wis. 308. Under that rule a foreman, or other person superior in authority and responsible to another as master, and the men under him, so far as relates to the work in which they are jointly engaged, though in different capacities and though such foreman or other person has authority to hire and discharge such men, are fellow-servants. But we will not pursue this subject further or decide this branch of this case. Some attention has been given to it so the case will not be referred to hereafter as holding that in such a situation as the one in *539question the promisor must be regarded as standing in tha place of the master.
We may now proceed to the next and vital point in tha case on the assumption, for the purposes of the decision, that it was actionable negligence for defendant to leave the lubricator glass unguarded; that the duty to attend to that matter was intrusted to the engineer; that as the engine left the engine house respondent objected to continuing in defendant’s service unless it was attended to, and that tha engineer then promised to do so.
Now it is claimed bjr counsel for appellant, and conceded by respondent’s counsel, as is the law, that if an employee object to continuing in the service of his master because of some danger attending the same which it is the duty of the latter to remedy, he may, relying upon the master’s promise to perform that duty, remain in such service for such reasonable length of time as may be required for that purpose, if the danger be not so obvious and immediate that from his standpoint it should be remedied at once; yet when such reasonable time shall have expired and the servant knows, or by the exercise of ordinary care ought to know, that the danger still exists, if he remains in the service and subjects himself to such danger he is chargeable with that form of contributory negligence known as assumption of the risk and is remediless for any injury that thereafter happens to him thereby.
When did the time expire within which the engineer should, in all reason, have redeemed his promise to place a guard upon the lubricator glass ? The trial court seems to have determined from the undisputed evidence, as a matter of law, thafiit expired when the engine left the Milwaukee depot to go on the trip. That is clearly shown by the way the special verdict was-framed. It contains findings favorable to respondent in regard to whether the engineer placed a shield upon the lubricator glass before the engine started *540on the trip and whether respondent knew when such trip commenced that the glass was still unguarded, and the case was made to turn on such findings. However, strangely enough, the jury also found that plaintiff did not continue in defendant’s employment longer than was reasonable for a person of ordinary care and prudence, under the circumstances, to expect that the engineer would procure the shield and place it upon the lubricator. That finding, with the others referred to, seems to convey very inconsistent ideas. Together they say a reasonable time to procure the shield and place it upon the lubricator expired when the engineer started out on his trip, yet respondent, as a person of ordinary care and prudence, may reasonably have expected the time for remedying the danger complained of had not fully expired when the injury happened, some three hours after the engine left Milwaukee.
That the promise should have been redeemed before the engine left Milwaukee, and that respondent so expected if he had any expectation that the lubricator glass would be guarded for the trip he was about to make, is too clear for reasonable controversy. There was no need for submitting that question to the jury, nor any other question bearing on the subject. The evidence was all one way that respondent had no personal interest in the condition of the lubricator except for the trip he was about to enter upon. He had never before been out with that engine, and of course did not know that he would be called upon to do so again. The place to procure the shield was at the roundhouse in the city of Milwaukee, which the engine was leaving when the promise was made, and to which it did not thereafter return. A few moments after the promise was made, and without any absences of the engineer to give respondent ground to believe that he had made a trip back to the roundhouse, the engine moved to the vicinity of the Milwaukee depot, a considerable distance away, and there it remained *541nearly two hours before the start on the trip was made, during which time the engineer remained with it to the respondent’s knowledge, and the latter was in the engine cab attending to his duty of keeping up steam, which duty required him to often look at the steam gauge located a little under the lubricator glass. If respondent expected the shield to be placed on the glass before going out on the trip, and we think the circumstances all indicate that he did not, when the opportunity for doing so no longer existed, obviously, the time for redeeming the promise had expired.
The verdict of the jury, to the effect that the time for removing the danger complained of had not expired when the accident occurred, is certainly without any evidence to support it. That finding is the only one directly on the subject of when the period covered by the promise expired, though, as before indicated, the way the verdict as a whole was framed shows that the trial court’s view was, as the fact is, that such period can by no stretch of reason be extended into the time when the engineer no longer possessed the means of redeeming his promise before leaving the city of Milwaukee on the trip.
The conclusion from the foregoing is that, by going out on the trip under the circumstances, respondent assumed the risk of the condition of the lubricator, if he knew or ought to have known that the engineer had failed to keep his promise. The jury said he did not know that fact when the trip commenced, and that he proceeded relying on the promise. It is impossible, in our view, to find any reasonable ground in the evidence for those findings. They are contrary to all reasonable probabilities and contrary to the evi•dence of respondent. He regarded the absence of the shield as rendering his working place exceedingly dangerous. He knew that such absence was liable to result at any instant, and without any warning whatever to enable him to avoid it, in inflicting upon him a serious bodily injury. Every *542reasonable probability supports the idea that his attention, was naturally drawn, or should have been, to the condition of the lubricator, many times before he left Milwaukee. True, on principle he had a right to assume that the engineer’s promise would be kept, but he could not continue to so assume when he had the evidence to the contrary right before him. If the defect had been located where it would not naturally have come under his observation, the presumption mentioned would excuse ignorance to a certain extent of the true situation; but it was not so located. The difficulty was in his immediate surroundings, at a point where he could not fail to observe it by reasonable attention to such surroundings. We may well say that it would have been very difficult if not well-nigh impossible for him to have worked in and about the engine cab two hours without observing the absence of the shield if he had tried to avoid seeing it. Much of the time he was where he could easily have reached the lubricator glass with his hand. It was many times within the range of his vision as he was about his work. It was not over two or three feet in front of him as he stood facing the boiler in the act of looking at the •steam gauge or performing other duties, where he must necessarily have stood on many occasions, and it was only a little more than one foot above the level of his eyes. The idea that respondent worked within a few feet of the lubricator for two hours before leaving Milwaukee, yet did not observe that the glass remained unguarded, since the unguarded condition was deemed by him to be exceedingly dangerous, is so improbable that the wonder is how it could have found a place in the verdict or been approved by the trial court. The salutary limitation upon the power of a jury should not be forgotten, while, at the same time, such power should be firmly maintained to its full limit. As to what is the truth as established by evidence, within the realms of reasonable .probability, in contemplation of law the judgment of a jury *543is well-nigh infallible, and when approved by the trial judge is so. If they were permitted to go beyond that, the best system human wisdom has yet devised for discovering the truth would be sadly deficient indeed.
If respondent had testified that he looted at the lubricator and did not observe the absence of the shield, or, without having affirmatively testified that he so looked, had testified that he did not know of the absence of the shield at any time after the engineer’s promise was made, the situation would not be changed. The finding of the jury would still be against all reasonable probabilities. But he did not so testify. His testimony is rather to the effect that he did know the true situation all the time up to the instant of the injury. He seems to have appreciated, in giving his testimony, the extreme improbability of a person circumstanced ás he was being ignorant of those things which were almost before his eyes; so he contented himself in saying that he did not pay any attention to the condition of the lubricator. Counsel for defendant tried patiently, by a long and fair cross-examination, the record of which occupies many pages •of the printed case, to obtain a direct answer from respondent as to whether he knew when the engine left Milwaukee that there was no shield upon the lubricator glass; and the trial judge participated to the same end, endeavoring by repeating the counsel’s question and striking out nonrespon-sive answers and commanding the witness to answer responsively; still he persisted in saying that he did not pay any attention to the matter. After the many evasive answers referred to, the witness’s attention was called to his examination under oath on a former occasion, and he then .admitted that the following questions were there propounded to'him and that he gave the following answers thereto: Q. Ho you swear that you did not see whether or not there was a shield on when your engine left the city of Milwaukee that night? A. After I spoke to the engineer about *544the shield I paid no further attention to it. I knew that there was no shield on there. If there was I would have seen it. Q. You knew when you started out from Milwaukee that there was no shield on the lubricator, did you? A. Yes, I knew all the while there was no shield on the lubricator. If there had been one I would have seen the shield. Q. You still swear that you knew there was no shield on it when your engine started from Milwaukee? A. No; there was no shield on there. If there had been a shield on I would have known it. I paid no more attention to it.” That was followed by questions as to whether the witness still adhered to his previous statements, as follows: “ Q. Do you remember that testimony? A. Yes. Q. And that is true, is it? A. Yes.” His answer, repeated many times, in terms or effect that he did not pay any attention to the lubricator after notifying the engineer of the absence of the shield, was entirely consistent with his knowing as a fact, when he left Milwaukee, that the shield was not in place. One cannot read his testimony as a whole and come to any other reasonable conclusion than that, from the physical situation, he must have been fully informed as to the absence of the shield, and that such testimony contains a full confession to that effect. The court should have so decided on the motion to direct a verdict for defendant, and failing in that should have so decided on the motions made on behalf of defendant after verdict, including the motion for judgment in its favor.
"When the time expired for the engineer to redeem his promise, under the circumstances indicated, respondent was no longer protected thereby in his right to hold defendant responsible for the consequences of the danger, if it be conceded that the promise had that effect at all. In proceeding thereafter in defendant’s service, he voluntarily assumed the risk of which he had complained, as a part of his contract of employment, and is remediless for what followed. *545That is very:unfortunate; but the law must not be turned aside from the definite lines upon which it has been established in order to fit the necessities of a party in a particular case. That cannot be done for the benefit of one person without committing a great wrong upon another. Neither can juries, as before indicated, be permitted to find one way to recompense an unfortunate person for his injury, when all reasonable probabilities are the other way. Badger v. Janesville C. Mills, 95 Wis. 599; Roth v. S. E. Barrett Mfg. Co. 96 Wis. 615; Cawley v. La Crosse City R. Co. 101 Wis. 145; Lee v. C., St. P., M. & O. R. Co. 101 Wis. 352; Baxter v. C. & N. W. R. Co. 104 Wis. 307, 330; Wunderlich v. Palatine F. Ins. Co. 104 Wis. 382. Courts must not overstep those wise limitations upon remedies for misfortunes, however serious they may be, to award compensation therefor. They fall within the maxim, darnmwm absque injwria.
