delivered the opinion of the court:
The only error assigned and argued by appellant is, that the court erred in giving instructions for appellee and in modifying an instruction asked by appellant. The first instruction given for plaintiff below was as follows:
“The court instructs the jury, that while, as a matter of law, the burden of proof is upon the plaintiff, Dougherty, and it is for him to prove his case by a preponderance of the evidence, still if the jury find that the evidence bearing upon the plaintiff's case preponderates in his favor, although but slightly, it would be sufficient for the jury to find the issues in his favor and to find a verdict against the defendant, Donley.”
This form of instruction was given by the trial court and approved by this court in the case of Taylor v. Felsing, 164 Ill. 331.
The fourth instruction was, that if the jury believe, from the evidence, the hay-cutter was defective as charged, and the plaintiff notified the defendant of such defect, and that such defect rendered plaintiff’s services dangerous, whereupon the defendant promised to have the hay-cutter repaired, then “if you further believe, from the evidence, that the plaintiff thereupon relied upon the said promise of the said defendant to repair said hay-cutter, and that the said plaintiff continued in his said employment a reasonable time to permit the defendant to repair said hay-cutter, the plaintiff was not then guilty *584of negligence in continuing to use said hay-cutter for a reasonable time.” It would have been more proper, perhaps, to have told the jury that under such circumstances the plaintiff had a right, under the law, to continue in the employ of the master relying upon such promise, but the effect of tlie instruction was in substance the same. This rule is approved in the cases of Missouri Furnace Co. v. Abend, 107 Ill. 44, Swift & Co. v. Madden, 165 id. 41, and Illinois Steel Co. v. Mann, 170 id. 200.
The eighth instruction given on behalf of the plaintiff told the jury, in substance, that if any witness was in the employ of either plaintiff or defendant, such relation might be considered, together with any other relation which existed between such witness and such party to the suit, and that such interest, if any is shown by the evidence, might be considered by the jury in determining the weight to be given the testimony of such witness, taking the same in connection with all other evidence in the case and the facts and circumstances proven. There was no substantial or reversible error in this instruction. It is always proper for the jury to consider the interest, if any is shown by the evidence, which a witness has in the result of the suit, in determining his credibility.
In the first instruction offered by defendant, which was modified and appears as the ninth instruction, the jury were told that to authorize a recovery the plaintiff must prove, by a preponderance of the evidence, that he was exercising that degree of care and caution at the time of the injury which a reasonably prudent and cautious man would have exercised under like circumstances, and the court added thereto, “and in the situation that plaintiff was placed, as shown by the evidence.” There was no substantial error in this modification. Whatever situation the evidence showred the plaintiff was in at the time he received the injury, was the position in which he must necessarily have been expected to exercise such care and caution.
*585There was no reversible error in the giving or modifying of instructions, and the judgment of the Appellate Court for the First District affirming the judgment of the superior court of Cook county is affirmed.
