1 I. Plaintiff is a brickmason by trade, and in November, 1893, he was employed to work on a building being erected by defendant at Farley, Iowa. While so ■engaged, he, with others, was on a scaffold that, because of the weight thereon, fell, and plaintiff was injured; and this action is for damages sustained by him, under a claim that •defendant was required to and did erect the scaffold, and in so doing was negligent, because of which he (plaintiff) was injured. The answer put in issue the claim that defendant was required to make the scaffold, or that he did erect it, or was guilty of negligence. The issues were tried to a jury that returned a general verdict for defendant and special findings that Charles Anderson and George Loomis built the scaffolding on the north part of the building, including the part that fell, and that defendant did not do any of the work in building or directing the building of the scaffold which fell. A ground upon which rests the claim that defendant was required to erect the scaffold is that he agreed so to do at the time of plaintiff’s employment. The averment to that effect in the petition being •denied, the court gave to the jury the following instruction: “There has also been testimony introduced before you bearing upon the question as to whether or not defendant entered into any contract by which he agreed to construct and furnish all the necessary scaffoldings for the hrick and stone work upon the building in question. You are instructed that the testimony so introduced will not warrant you or justify you in finding that such contract was made, and you will therefore assume as a fact that no such contract was made.” The effect *278of the instruction was to settle the issue, as to an agreement by-defendant to construct the scaffolding, favorably to him, on the ground that the evidence would not justify a finding against him. To sustain the instruction, the record must show the evidence to be so in favor of defendant as to be without substantial conflict. The record is clearly against such a conclusion. It appears from the evidence that plaintiff’s father is a brickmason and contractor, and that plaintiff and others, who are bricklayers, came to work on the building in pursuance of a talk between defendant and plaintiff’s father. At the time of this talk, plaintiff, his two brothers, and others were at work for plaintiff’s father on another job, and they came to defendant’s job as a result of an understanding between the father and defendant. If there was ever an agreement that defendant should erect the scaffolding-himself, it was during the talk referred to. The father is a witness for plaintiff, and he states, in terms unmistakable, that defendant preferred and agreed to make the scaffolds. We give a part of the father’s testimony, to show its character. Referring to defendant, the witness said: “He says: ‘We want to build every scaffold. While the bricklayers are building on the north side of the building, we will build the scaffold on the other side, — me and my sons; and, if I need any help, I can get the help down in Earley cheaper than I can here, — if I need any more help.’ Says I: ‘If you want to build your own scaffolds,-Mr. Loomis, you know what it is. Scaffolding is the most particular business in that trade/ ‘Well,’ he says, ‘hadn’t I ought to know how to build a scaffold, — a man that puts up so many building as I doT ‘Well,’ says I, ‘you ought to.’ ‘Well,’ he says, ‘if you will let me have these men to work for me, I will give them a good scaffold.’ ‘I will give them a good scaffold, and take care of them,’ he says. Says I: ‘That is all right, Mr. Loomis. I trust to your word.’ ” It appears from the testimony of this witness that he, his two sons, and the defendant were all that were present when the talk took place. The two sons-*279were witnesses for plaintiff, and corroborated tbe testimony of the father as to defendant’s statements about building the-scaffolds. The defendant just as explicitly denies any such: talk or understanding. There is no basis for a reasonable-denial that the evidence on the question is in substantial conflict. It is defendant’s theory that he did not employ the men,, but contracted with plaintiff’s father to furnish the men to-do the work for specified daily wages, payment therefor to-be made to the father, and he to pay the men as his employes,, and that the building of the scaffolds was a part of the work, for which the men were employed. The law of this state as to. the obligation of a master to provide a safe place to work is. well settled. See Fink v. Ice Co., 84 Iowa, 321; Haworth v. Manufacturing Co., 87 Iowa, 765; Blazenic v. Coal Co., 102 Iowa, 706; Corson v. Coal Co., 101 Iowa, 224; Humpton v. Unterkircher, 97 Iowa, 509. In view of the well-settled rule of these cases, the question of who was plaintiff’s-, employer was important, as was also the character of the-employment; that is, ivas the building of the scaffolds a part: of the work to be done by the masons, or was the place to worlc to be provided by defendant? This question of fact was. plainly in issue. The instruction in question settled that: issue against plaintiff, to his prejudice, in view of the unmistakable conflict of evidence. The argument in support of* the action of the court goes to the question of what the evidence proves. We do not think that is the proper test. The-weight of the evidence settles that. The question we consider-is, had the plaintiff a right to the judgment of the jury as to what was proven, in view of the evidence before it? We-are clearly of the opinion that he had, and that the court erred: in giving that instruction.
*2802 3*279II. The court gave the following instruction: “Under-the uncontradicted evidence in the case, according to the-custom of bricklayers, the duty of building the scaffold in-question, in the absence of a specific contract, was devolved' upon the plaintiff and his fellow bricklayers and helpers;. *280«nd, if you find from the testimony that they, or some of them, built the scaffold that fell down and caused the injury of which the plaintiff complains, then you are instructed that 4he plaintiff cannot recover against the defendant, even though .you should find that the defendant’s son, George Loomis, assisted said bricklayers, or their helpers, or some of them, in doing the work upon said scaffold, and your verdict should be for the defendant.” The complaint is that no such custom was pleaded,.and it is true that none was. Such a custom has not the force of law, so that the parties are presumed to have contracted with reference to it. That parties may contract with reference to a custom known to them is well settled. Hughes v. Stanley, 45 Iowa, 622. The custom referred to in the instruction, to render it a part of the contract, must have been considered in reaching the agreement. Windland v. Deeds, 44 Iowa, 98. Such a contract, if used to defeat a recovery, changes the issue from that presented by -the petition and answer, and should be pleaded. In Lindley v. Bank, 76 Iowa, 629, it was sought to take advantage of a custom to change the effect of a contract as pleaded, and the right was denied because the custom- was not pleaded. So far as we know, the practice in this state, to make such a custom available, as affecting a contract, is to plead it. Hughes v. Stanley, supra. It would seem to be the reasonable rule, and in harmony with section 2704 of the -Code of 1873, where the answer is a denial, as in this case: “Under a denial of an allegation, no evidence shall be intro-duced which does not tend to negative some fact, the party making the controverted allegations is bound to prove.” Proof •of such a custom.did not negative any fact plaintiff was bound to prove, and the statute seems clearly applicable. It is said the evidence was admitted without objection. Such a fact would not justify the instruction, if otherwise erroneous. The most that could be said would 'be that the evidence could be considered under the issues formed. The admission of immaterial evidence will not justify the presentation of new issues in the instructions.
*281Tbe case involves other errors that need not be separately noticed, as they seem to follow the conclusion of the court in holding the evidence insufficient to present a question of fact to the jury, as stated in the first division of the opinion. Complaint is made of a remark by the court, during the examination of a witness, that we need not set out or consider, as a repetition of it will not likely occur on another trial.— Reversed.
