Plaintiff’s decedent, Jacob Lehman, was a carpenter, but sometimes did other work. He was killed while in the employ of E. A. McGeorge & Son, who own and operate an elevator at Gladwin, Michigan, who had elected to come under the workmen’s compensation act, whose insurer was the Fidelity & Deposit Company. Although little testimony upon the subject was elicited, it seems to be conceded that Lehman was making some repairs about the place, working as a carpenter. In the morning of August 12, 1915, he was found standing, in contact with the metal siding of the elevator building, dead. Surviving him are his widow and three minor children. His widow, since remarried, is administratrix of his estate, and, assuming that the death of her husband was caused by a current of electricity and that the defendant, whose wires entered the elevator and who furnished the own-* ers electric energy for power and lighting, was negligently responsible for charging the metal siding of the building with electricity, she brought this suit against it under the death act, filing her declaration in August, 1916. With the plea defendant gave notice that it would prove that after Lehman’s death the plaintiff “accepted and received benefits as provided for by said workmen’s compensation act,” by reason of which she is barred from maintaining this action. Upon the trial the jury returned a verdict for plaintiff for $8,-300, upon which judgment was entered. Various ex*700ceptions were taken at the trial, upon some of which assignments of error, nine in number, are based, those relied upon in the brief being (1) a refusal to strike out certain testimony, (2) refusal of the court to direct a verdict for defendant when plaintiff had rested, (3) refusal to direct a verdict for defendant at the close of the testimony, (4) a statement made by the court in the charge, “The death, there is no question about, was instantaneous,” and “This man was instantly killed,” (5) an erroneous instruction concerning the measure of damages, (6) the instruction,
“I do say to you as a matter of law * * * that there was not such an agreement made by the widow relative to the compensation as precludes her from bringing this suit.”
1. The contention of appellant that this plaintiff can not maintain this action is first considered. Sections-5468 and 5488, 2 Comp. Laws 1915, read as follows:
“(5468) Sec. 15. Where the injury for which compensation is payable under this act was caused under circumstances creating a legal liability in some person other than the employer to pay damages in respect thereof, the employee may at his option proceed either at law against that person to recover damages, or against the employer for compensation under this act, but not against both, and’ if compensation be paid under this act the employer may enforce for his benefit or for that of the insurance company carrying such risk, or the commissioner of insurance, as the case may be, the liability of such other person.”
“(5488) Section 1. If the employee, or his dependents, in case of his death, of any employer subject to the provisions of this act files any claim with, or accepts any payment from such employer, or any insurance company carrying such risks, or from the commissioner of insurance on account of personal injury, or makes any agreement, or submits any question to arbitration under this act, such action shall constitute a release to such employer of all claims or demands at law, if any, arising from such injury.”
*701The testimony discloses that the employer and the Fidelity & Deposit Company, before this suit was begun, paid the widow of Lehman, the plaintiff here, sums of money. The exact amount is not made certain, but it seems to have been at least $129 or $130. The widow was advised about her rights and she understood that she could either accept payments of $7.21 a week or she could sue the defendant here, as she has done: Plaintiff gave testimony as follows:
“Q. Isn’t there an agreement between you and the insurance company that you can claim your compensation at any time that you desire to do so?
“A. No, no agreement.
“Q. There is not? (No response.)
“Q. And before determining whether or not you will claim that compensation you are waiting the outcome of this lawsuit are you not?
“A. Yes, sir.
“Q. And that is the understanding that you have with the attorneys in this case?
“A. Yes, sir. * * :1:
“Q. Well, there is an agreement that if this case fails that you shall then continue to get your compensation, that is true, isn’t it, Mrs. Brabon?
“A. I think so.
“Q. Well, you had a talk and you know that if you don’t get any money in this case then your understanding and your agreement is that you are to get your compensation?
“A. Do you mean so much a week?
“Q. Yes, for the death of your husband.
“A. For how long?
“Q. Well, for the 300 weeks, for the balance of the 300 weeks.
“A. I don’t know. * * *
“Q. You are now awaiting the outcome of this case to determine as to whether or not you will accept additional compensation, are you not, Mrs. Brabon? * * *
“A. Why, of course I am waiting to see the outcome of this—
“Q. Waiting for what, Mrs. Brabon?
*702“A. I am waiting for this—
“The Court: ‘To see the outcome of this’ is the way she answered.
“Q. Yes, and if you don’t recover in this case, it is the understanding and the agreement between the parties that you are then to receive your compensation, is it not? * * *
“A. Well, I haven’t agreed to nothing like that. * * * I have not entered into a contract with my attorney as to what percentage he shall obtain as fee in event of a recovery in this case * * * I did not sign an agreement regarding compensation in this case.”
It does not clearly appear that any formal claim for compensation was made by the widow to the employer, and it does not appear that any agreement about compensation was made or that any document or agreement about it was filed with the industrial accident board. There is some testimony to the effect that she was offered money by the employer and urged to accept it but, for a time at least, refused it. It is, however, a reasonable, if not a necessary, inference from the testimony that the widow understood that the sums paid to her were not mere advances, or charitable gifts, but were paid to her on account of an admitted right which she had to look to the employer for compensation.
The employer wrote two letters which indicate its attitude in the premises, one dated October 7, 1915, the other the next day, which are here set out:
“Mr. A. J. Spalding, Adjuster
“Fidelity & Deposit Company of Baltimore, Maryland,
“Detroit, Michigan.
“Dear Sir: Regarding the case of Jacob Lehman, the widow came to our office Wednesday, October 6th, and asked if I could let her have some money. I let her have a check for $7.21 which is the amount you advised we should advance. This is the first time that she has asked for or accepted money from us since the accident and we would like to know if you people can*703not arrange to send her the correct amount weekly from now on.
“Kindly let us have a prompt reply.”
“Mr. A. J. Spalding,
“Detroit, Michigan.
“Bmr Sir: We learned today in a round-about way that Mrs. Lehman has decided to accept her compensation as advised you yesterday we advanced her $7.21 on October 6th. You will kindly advise the Fidelity & Deposit Company of Maryland to take care of the weekly payments in the future.”
In cases arising under the compensation act, it is the rule that the terms of any agreement made by the employer and employee or his dependent claimants, concerning compensation, to be binding, are subject to the approval of the industrial accident board, which will not approve settlements, or agreements therefor, not in conformity with the act. The agreement is not final and binding until filed with and approved by the said' board. If the employee has the right either to sue his employer at law or to take compensation under the statute, and he sues and later files a claim for compensation, the action at law will abate; because by the terms of section 5488, above quoted, in filing his claim he has released to his employer all demands at law. Gray v. Brown & Sehler Co., 200 Mich. 177. If the employee is injured by the negligence of a third person, he may elect to sue that person or to claim compensation under the statute (Grand Rapids Lumber Co. v. Blair, 190 Mich. 518; Albrecht Co. v. Iron Works, 200 Mich. 109; Dettloff v. Hammond, Standish & Co., 195 Mich. 117), and if he claims and is paid compensation, the amount which is paid becomes the measure of- the recovery of his employer against the third person. Beyond this, it was intimated in Grand Rapids Lumber Co. v. Blair, supra, in agreement with Thompson & Sons v. Engineering Co., 1 K. B. (1903) 428, Nettleingham & Co. v. Powell & Co., 1 K. B. *704(1913) 113, that if compensation is voluntarily paid by the employer under an agreement to do so, not formally sufficient to satisfy the statute or bind the employee, the employer may sue the responsible third person for indemnity, having to satisfy the court that the amount claimed was properly'paid by him.
In the instant case, the alleged responsible third person pleads, in effect, that the representative of the employee had proceeded against the employer for compensation under the act before bringing this suit, and, as she cannot proceed against both the employer and the defendant, the suit must abate. And this raises the precise question to be determined, namely, did she proceed against the employer for compensation, within the meaning of the statute? There is no statute definition of the word proceed. Particulars of conduct which would release to the employer, no third person being responsible, any right of action at law against him, namely, filing any claim, accepting any payment, making any agreement with reference thereto, recited in section 5488, are not repeated in section 5468. In Dettloff v. Hammond, Standish & Co., supra, the Widow and administratrix, before suing the alleged responsible third person, made an agreement with the employer, by the terms of which she was to sue the responsible third person, saving and reserving her right to compensation under the statute. If she received less than she would be entitled to receive under the compensation act, the employer, party to the said agreement, was to pay her the difference. Whether it was a good or bad agreement, in law, it was an agreement with respect to compensation, not submitted to or approved by the industrial accident board. As affecting the construction of the statute and the precise question presented in the instant case, the decision in Dettloff v. Hammond, Standish & Co. is that the mere making of the agreement was not a proceeding *705fco obtain compensation under the act. No money had been demanded from or had been paid by the employer, who therefore had no claim to be indemnified by the wrongdoer. In short, all there was done was held not to evidence an election to proceed against the employer for compensation and to evidence an election to proceed against the responsible third person.
Here, the claimant widow has accepted some compensation from the employer, paid voluntarily, it is true, but under circumstances which, if payments were completed and accepted, would undoubtedly give him a right of action against the responsible wrongdoer for indemnity. Her loss resulting from the injury has been pro tanto reduced — satisfied—by the money she has accepted. If she may thus accept compensation for 20 weeks and then sue the wrongdoer, she may accept it for 100 weeks or more and sue the wrongdoer.
These and other considerations point to the conclusion that, within the meaning of the statute, she had proceeded against the employer before bringing this suit, as, in a supposed case, demand upon and settlement with the responsible wrongdoer would be considered to be a proceeding against him. Mulligan v. Dick & Son, 41 Sc. L. Rep. 77.
On the other hand, we have legislation which requires interpretation and, in the administration of the law, application, in harmony with its general purpose. It both creates a liability and provides a method for enforcing it. To proceed under it, against an employer, is to give notice of an injury, make a claim for compensation, secure the judgment and finding of the board upon all points involved, or its approval of any agreement for compensation which the interested persons may enter into. Finally, if it is desired, a judgment may be had, in conformity with the conclusions of the board. Little difficulty-is experienced *706where the facts are like those presented by this record, but in a large number of cases, perhaps in a majority of them, the original findings may be controlling for a limited period only, and subject upon certain conditions to revision and amendment. To proceed against the employer is. to employ the procedure, the method, pointed out in the statute. If the particular provision of the law is interpreted in harmony with this idea and view, questions like the disturbing one now being considered cannot hereafter arise, or, arising, may be disposed of by a certain rule. Tested by such a rule, plaintiff has not proceeded against the employer because she has neither made with him an approved agreement nor has she submitted a demand against him to lawful determination.
It is held, in agreement with the ruling of the learned trial judge, that plaintiff may maintain her suit.
2. The testimony which the court refused on motion to strike out was the answer of a witness to the question,
“In your opinion would it be possible for that primary wire to jump over on those places you have spoken of, those bare places?”
The witness, who had formerly worked as lineman for defendant, answered, “It would be possible under certain conditions.” The objection was,
“I object to that and ask that it be stricken out-as to what would possibly happen.”
The point presented in argument is that negligence of defendant cannot be made to rest upon mere possibilities. But the effect of this testimony was not to prove possible negligence or possible instead of probable conditions. An impossible condition can never be a probable one. A possible condition may or may not be probable. Usually, a subject cannot be developed *707by one question and answer, and it ,was not error for counsel to ask the witness, supposed to have extra knowledge, about certain phenomena and their causes, if it is possible that a certain result, or effect, or condition, may come from stated conditions. If no more was proved, the testimony might be wholly immaterial as affecting the issue of fact presented, depending somewhat upon the degree of care which the law required to be exercised in the premises. This witness was cross-examined and is commended by counsel for appellant for his frankness. Just what he knew and what he guessed at was made plain.
3. Two reasons were given for requesting a directed verdict when plaintiff had rested her case, namely, (1) no actionable negligence had been established, and (2)' the cause of the accident rested in speculation, guess, conjecture.
The testimony tended to prove that the person who discovered plaintiff’s decedent, dead, received an electric shock when he touched the body. It was not until the current was shut off that he was moved. It tends to prove, further, that there were several large burns on his person, and on the bottoms of his feet a number of holes having the appearance of being made with a hot iron. In the opinion of the medical man called to see him, he was electrocuted. At the point where the wire carrying the current for lighting entered the elevator,
“The metal had been- melted and looked as though it had been soldered together. Where the fire went in, a hole had been burned the size of a bowl.”
No other wires than defendant’s entered the building. Near the building was a transformer, on a pole to which a primary wire carrying 2,300 volts was run and from which the wire for the lighting current ran to the elevator. Normally, this secondary wire carried 110 volts, perhaps 220; the record does not seem *708to be quite clear upon this point. Formerly, another than defendant had furnished current for the elevator. A circular loom conduit led through the wall, and through it the wire passed. It was not a porcelain tube, but made of other material. A witness, a former lineman of defendant, testified that
“A circular loom is not supposed to be used on buildings where it is exposed.”
The same witness testified that after the injury and after the fire which was set to the elevator building had been put out, he noticed the wires and where current had jumped from the primary wire to the lighting wire which led to the elevator. He testified to •certain bare joints and points on the wires — not insulated — and also that there were places where the high tension wire and the lighting wire were separated from each other not farther than three inches. He further testified:
“The wires were supposed to be insulated. At places, a majority of the joints were not soldered, being bare for a distance of an inch or an inch and one-half. This condition, I think, I found immediately after Lehman was dead. More bare joints were found on the transformer pole than in other points. I couldn’t say how many there were on the transformer pole, but would say three.”
It is unnecessary to further set out testimony. The morning was a rainy one. The jury was warranted in finding that the metal wall was electrified from defendant’s wire and that plaintiff’s decedent was killed —electrocuted—because thereof. There was evidence of faulty conditions of wiring. It was possible for the greater voltage to reach the secondary wire. No other cause for what occurred is suggested. Indeed, any other cause is eliminated. Inference from proven facts, and not conjecture, supports the finding of the jury.
*709The motion for a directed verdict, made at the close of the testimony, was based upon reasons already given and then repeated, and upon the further ground that plaintiff had elected to accept compensation under the act. What has been said disposes of the contention.
5. The court was not in error in saying to the jury that death of plaintiff’s decedent was instantaneous— that he was instantly killed. For the purposes of the point made, namely, that suit was improperly brought under the death act (3 Comp. Laws 1915, §§ 14577, 14578), there can be no question about the fact. The man was killed by a current of electricity received when he leaned against or touched the metal wall, and whether one or more minutes elapsed before life was extinct is not material. A verdict based upon another conclusion would have properly been set aside by the court.
•No reversible error is pointed out, and the judgment is affirmed, with costs to appellee.
