curred, and he was familiar with the boiler, the manner of its use, and its surroundings. About the month of December, 1884, the defendant procured a large steam-boiler, of some 100-horse power, to be built for it by B. XV". Payne & Co., of the city of Elmira. This firm was extensively engaged in the manufacture of boilers, and was of good credit and reputation in its avocation and business. The boiler was set up in the defendant’s manufactory, and commenced being used by it about that time, and continued to be used down to the time of the explosion. The engineer, and those employed by the defendant in and about the running and operating of the boiler, were, so far as the evidence shows, competent for the places they filled, and the explosion was in no way chargeable to any negligence on their part. XVhile the boiler was being used, and late in the fall of 1885, it was discovered that steam escaped from the middle of the horizontal beam, on the left-hand side, and'near the second plate on top. An experienced person was immediately called in by the defendant, and remedied the difficulty by caulking. It appeared that it was not unusual for steam to escape at the seams, and that the proper remedy was to caulk. In the middle of February, 1887, steam was again discovered escaping from the seam on top of the boiler, and again a competent person was called in, and again caulked it at that place. There is no evidence that steam of consequence escaped after that. In the month of April, before the explosion, the boiler was inspected and examined quite thoroughly by persons qualified for the duty, and found to be all right. Evidence was given tending to show (as discovered after the explosion) that the boiler was made from an inferior quality of iron, and that it was improperly built, in this, that in riveting the plates the holes were not properly drilled or the rivets properly set. It also appears that, so far as shown upon the surface, the iron appeared good, and that its defective character could only be discovered by cutting or breaking, and the defective riveting only by taking them out, because the heads entirely hid the holes from view. The boiler was inspected and examined by experienced men, giving their attention especially to the business, as often as once in four months during the whole time of its use, and pronounced safe. How the explosion occurred, or what caused it, does not appear. Some evidence was given tending to show that the defendant, through its officers, had personal knowledge of the leakage of steam and some other claimed defects in the boiler. The ordinary life of a steam-boiler, properly cared for, is from 20 to 25 years. Upon submitting the case to the jury, the learned judge, among other things, instructed them: “If the defects in this boiler were such as were known or discoverable by examination or the application of known tests, then the defendants .are chargeable, whether they knew it or not.” To this the defendant excepted. The defendant requested the following instructions: “If the jury find the explosion was caused by defects in the boiler which the defendant did not know of, and they used reasonable cave to ascertain all defects, then the verdict must be for the defendant.” This request the court refused, remarking that he would adhere to the rule before -stated. In connection with this matter, the defendant also requested the following instructions to the jury: “If the jury find that the accident was caused by the unskillful manner the riveting was done in the boiler by the manufacturer, and this defective riveting could not be discovered by reasonable inspection, and was unknown to the defendant, then negligence cannot be imputed to the defendant for such unskillful riveting.” This request the court denied, and, instead, the court say: “I say if it could be discovered by examination and the application of known tests.” To this and the preceding instructions and refusals the defendant excepted. These several propositions are closely allied.
In refusing the instructions asked for, and in charging the jury as aforesaid, we think the court erred. It is the duty of the master, and forms a part of the contract of hiring, to furnish for the use of the servant in the business
