The jury found specially, among other things, that the saw was defective, to the knowledge of John Blank, who was charged with the duty of seeing that it was kept in proper condition; that John Arndt was the acting foreman; that such foreman, with knowledge of such defect, directed plaintiff and his associates to run one heat, informing them that he would then have the saw changed; that plaintiff went to work relying upon such promise; that defendant was guilty of negligence which proximately contributed to the injury; that-plaintiff was not guilty of any. such negligence; and that he did not have sufficient knowledge and experience to enable him to know the risk of working With the defective saw prior to his injury. The verdict' was challenged as contrary to the evidence, and the ruling-of the circuit court in that regard, among others, is before-us for review.
That the saw was cracked and defective, to the knowledge of plaintiff, appears clearly from the evidence, and is-alleged in the complaint. The proof shows that he was a man of large experience with such machinery, and that he-had worked fourteen years in the mill where he was injured;, and four years in operating the machine where the accident occurred. His evidence, bearing on his knowledge of the danger, and his justification for working notwithstanding such danger, is substantially as follows: “ There were small rollers to carry the iron under the saw. Then the saw was *9pulled down onto the iron. I bad to stand alongside of the frame work. The frame was even with the plate. I had to shove the iron under the saw. I was about two feet from the saw when the thing happened. "When I came to the mill that morning, Ered Glaesner said to me: ‘The saw is cracked. Look at it.’ John Arndt, the foreman, was standing there. I said: ‘ John Arndt, will you change the saw ?5 He said: ‘ No; you wall have to work one heat with it. It will take till about 10 o’clock.’ I relied on that, and went to work. He did not say whether it was dangerous, or not,, that I know of. He said it was not dangerous. When they started, I was holding one end of the bar to be cut, Blank was holding the other, and Norton was handling the lever.” On cross-examination he said: “ I had worked in the mill fourteen years, and four years with the saw. There were-four men at work with the saw besides Blank, the foreman. There was no one in the crew that had worked with the saw longer than I had, and only one as long. I looked at the saw after Glaesner said it was cracked. The crack was about two or three inches- long. Nobody told me it was dangerous, or not dangerous, or said anything about that. The reason I asked Arndt if he was (going to change the saw was, I saw a crack in it. I asked it because I wanted to change my coat, and I knew if he was going to make the change I would have time. I went to work because the foreman said it was not dangerous. I don’t know that he had ever worked with the saw. I don’t know as I objected to-going to work. I don’t think I did. I worked by the ton; so, if I had not gone right to work, I would have lost part of a day’s wages.” John Norton testified, in substance, as follows: Before we started up, Erdmann told me the saw was cracked. I said to Arndt, “I think we ought to have-another saw.” He said, “ You will have to try and work the heat off.” That is all he said. The saw had started, but we had not commenced cutting. Erdman showed me the crack. *10It was about three inches long. It was open at the teeth. Erdman called my attention to it, and told me to bear down as gently on the lever as I could. I am sure of that. That is just as we were ready to saw the first bar. No one said anything in my hearing about its being dangerous, nothing of the sort. No one, that I know of, made any objection to going to work. John Sanowa testified as follows: “Arndt, the foreman, said the saw should be changed when the heat was out. He said we should work that heat; that is all. I was there till the saw was started, and heard all that was said. Hid not hear Erdman say anything to Arndt, or Arndt to Erdman.” Julius Blank testified as follows: “I told Arndt, before we started, that the saw was cracked. He said, when the first heat is out, we will change it. He did not say anything further.” There was considerable other evidence on the subject, but nothing to vary the above, on which the jury found, in effect, that plaintiff neither knew nor ought to have known of the risk of working with the defective saw.
A person thirty-five years of age, and of fourteen years’ ■experience with machinery, circumstanced as plaintiff was, must be presumed to know the operation of natural laws, and the dangers which such a defect as the one in question would naturally suggest to a person of ordinary intelligence. Walsh v. St. P. & D. R. Co. 27 Minn. 367. Otherwise, the risk that would attend the employment of labor in many manufacturing industries would be so great as to render it impracticable to carry them on. This presumption is too strong to be rebutted, so as to warrant a verdict to the contrary, merely by the evidence of the person whose knowledge is in question that he did not know of the existence of a danger which was obvious to a person of ordinary intelligence, even though not an expert.
But the verdict of the jury is not only wrong, tested by the rule above stated, but the evidence affirmatively shows, *11very clearly, that plaintiff was the most experienced man in the crew; that he knew more about the danger than Arndt; that the talk about changing the saw was, partly •at least, the result of a consciousness of such danger; and that, after such conversation was over and the saw was started, plaintiff directed that it should be let down onto the iron with great care, on account of its condition. From all the evidence and circumstances but one inference can reasonably be drawn, and that is that plaintiff knew of the danger as well as Arndt, and did not rely upon the judgment of anybody that it was safe to proceed with the work. The verdict of the jury in this regard is practically without any evidence to support it. There is no evidence but that of plaintiff that Arndt said the saw was not dangerous, and he contradicted himself respecting the matter in such a manner that the finding based on his evidence cannot be sustained. It follows that the plaintiff knew of the defect and of the danger as well as any one did, or could reasonably be expected to know. Therefore, he must be presumed to have assumed the risk, unless the case .comes within some exception to the general rule on the subject. Stephenson v. Duncan, 73 Wis. 404; Heath v. Whitebreast C. & M. Co. 65 Iowa, 737; Anderson v. H. C. Akeley L. Co. 47 Minn. 128; Showalter v. Fairbanks, M. & Co. 88 Wis. 376; Peterson v. Sherry L. Co. 90 Wis. 83; Hazen v. West Superior L. Co. 91 Wis. 208; Gibson v. Erie R. Co. 63 N. Y. 449; De Graff v. N. Y. C. & H. R. R. Co. 76 N. Y. 125; Hayden v. Smithville Mfg. Co. 29 Conn. 548; Olson v. McMullen, 34 Minn. 94; Devlin v. W., St. L. & P. R. Co. 87 Mo. 545.
But it is said plaintiff did not assume the risk because the jury found that he protested against working with the defective saw, and was induced to continue his employment •by the promise of Apndt to change it as soon as one heat was worked off. The general doctrine is well established that if an employee continues in the employment of the *12master with knowledge of any special or extraordinary risk attending the same, or under such circumstances that he is chargeable with such knowledge, he cannot recover of the master for any injuries received by reason of such risk. But to such general doctrine there is the exception for which counsel for plaintiff contends; that is, that when an employee notifies the master of a special risk, and objects to continuing the work under the existing conditions, and is induced to continue such work by a promise to remove the danger within a reasonable time, then for such time the employee is not presumed to assume such risk. Such exception has been often recognized by this court. Stephenson v. Duncan, 13 Wis. 404; Sweet v. Ohio C. Co. 18 Wis. 121; Corcoran v. Milwaukee G. L. Co. 81 Wis. 191. Does this case come within the exception? We will discuss that phase of the matter, assuming that there was a promise made to remove the danger, binding on the master, though that is open to serious question. Did plaintiff commence work, on the morning in question, relying on the promise to change the saw when the first heat was run out? He said he did; but that was his conclusion on a question of fact to be found by the jury, and it is entitled to little, if any, weight, under the circumstances. At the threshold of this question there is the essential element of protest or objection to proceed with the work on account of the danger. We fail to find any evidence of such objection or protest. Plaintiff’s evidence on that subject is: “I said, ‘John Arndt, will you change the saw?’” “I asked John Arndt if he was going to change the saw.” “ I do not know as I objected to going to work.” “ I don’t know as any one did.” “ I was paid by the ton.” “ If I had not gone to work at 6 o’clock, I would have lost part of my wages.” “ I asked him [Arndt] if he was going to change the saw, because it was pretty cold and I wanted to change coats, and, if he was going to change the saw, then I would have time to go and put on the coat.” From *13■this it is apparent that plaintiff did not object to working with the defective saw, and did not work with it temporarily in consideration of the promise to change it when the heat was off. He was anxious to commence work on time ■and put in a full day. It was not very material to the employer whether the work commenced at 6 o’clock or was •delayed till 10 o’clock, when the saw could have been ■changed, because the pay was by the ton, not by the day. The attitude- of plaintiff and his associates respecting the matter was merely one of inquiry, whether they were going •to be delayed or not, instead of one of objection to or protest against proceeding Avith the defective saw. So we conclude that the finding, to the effect that plaintiff continued the work in consideration of a promise to remove.a danger which he was unwilling to assume the risk of, is without evidence to support it.
But, if the finding of the jury last reviewed could be sustained, the doctrine that an employee can rely upon the master’s promise to repair within a reasonable time, to rebut a charge that such employee assumed the risk, is by no means without limitation. If the risk is so obvious and immediate that serious injury may probably result from a continuance •of the work, then the doctrine that the employee can proceed, relying upon the promise to repair or to remove the •danger, does not apply. Rothenberger v. N. W. C. M. Co. 57 Minn. 461. This exception to the exception, if we may call it such, is supported by several good reasons, among which are that it is not consistent with reasonable prudence for one to submit himself voluntarily to imminent danger of probable immediate serious injury, relying upon a mere promise on the part of anybody that such danger will be removed after a time; and further, that, when such danger' exists, there is no such thing as a reasonable time to repair, other than presently and before the Avork proceeds further. To be sure, there are respectable authorities that go so far-*14as to bold that a promise by the employer to repair relieves the employee of the consequences of the risk, though the danger be constant, immediate, and serious; but the weight of authority and the doctrine of this court are the other way. Showalter v. Fairbanks, M. & Co., supra. The true rule is well stated in the opinion by Mr. Justice Elliott in Indianapolis St. L. R. Co. v. Watson, 114 Ind. 20, as follows: “ If the services cannot be continued without constant and immediate danger, and the danger and its character are fully known to the employee, he assumes the risk if he continues the employment.” Discussing the subject, Justice Elliott says further, in effect, it is a fundamental principle in this branch of jurisprudence that one who voluntarily incurs a known and immediate danger is guilty of contributory negligence, and we are unable to see why a promise should relieve a party from his own contributory fault. If the danger is not great and constant, then such promise may well be deemed to relieve him; but when it is great and immediate, and of such a nature that a prudent man would not ordinarily incur it, a promise does not nullify or excuse the contributory negligence. To the same effect are Ford v. Fitchburg F. Co. 110 Mass. 240; Hough v. Railway Co. 100 U. S. 214; Indianapolis U. R. Co. v. Ott, 11 Ind. App. 564; Chicago D. F. & F. Co. v. Van Dam, 149 Ill. 337; Rothenberger v. N. W. C. M. Co. 57 Minn. 461; Atchison, T. & S. F. R. Co. v. Midgett, 1 Kan. App. 138.
It follows, from the foregoing, that in order to bring a case within the exception to the general rule, that the employee by continuing in the employment of the master with knowledge of defects in machinery at which he is employed assumes the risk attending such employment, it must be shown, not only that he called the master’s attention to such defects and in some way objected to assuming the risk, but that the master expressly or by implication promised the employee to remedy the same within a reasonable time, and *15that the employee continued in the employer’s service relying upon such promise. That will rebut the presumption of contributory negligence and assumption of risk on the part of the employee, and create a presumption that, for the reasonable length of time requisite to enable the employer to remove the danger, the former does not assume the risk, and may prudently continue the work. But if the evidence shows that the danger is immediate, constant, and great, so that a reasonably prudent person ought not to subject himself to it, then the latter presumption is overcome, and the employee has no right of action, in case of an injury because of such danger, on account of his contributory negligence.
It follows, from the foregoing, that if the finding of the jury respecting the agreement to change the saw, and the continuance of the work by plaintiff relying thereon, could be sustained, if the danger yms obvious, immediate, constant, and the probable consequences the infliction of serious bodily injury upon plaintiff, it was negligence upon his part to rely upon such agreement. That such was the situation is too plain to admit of serious discussion. It does not require an expert, even, to understand that a saw four feet in diameter, running at a speed of 1,700 revolutions a minute, cracked three inches from the outside, when let down upon a large iron plate or bar and operated with sufficient force to cut it in two, is in danger of flying to pieces and seriously injuring all who may be in the vicinity. That a person of plaintiff’s experience with such a machine did not know of such danger is beyond comprehension. It was negligent to the point of recklessness to work 'with such a defective saw at all, under the circumstances. That brings the case clearly within the exception to the rule that a protest by the employee to continuing in the employment of the master because of the existence of some special risk attending it, a promise by the employer to remove the danger within a reasonable time, and a continuance of such employment in con*16sideration of such promise, relieves such employee from tbe ■chai'ge of contributory negligence, if injured because of such danger within such time. It follows that the finding of the jury in respect to plaintiff’s contributory negligence is without any evidence to support it on any theory of the case.
There are several errors assigned, not referred to, but the conclusion to which we have arrived renders it unnecessary to consider them.
By the Court.— The judgment of the circuit court is reversed, and the cause remanded for a new trial.
