This is an action by an employee to recover damages for personal injuries. The defendant is the Yeneer Manufacturing Company, which has in use several large vats, each 20 feet long, 10 feet wide and 6 feet deep, filled with boiling water, in which large logs are subjected to the moist heat to soften them for veneering purposes. These vats are parallel to each other, in the same room, and are surrounded by narrow platforms 5 or 6 feet wide, on which the plaintiff, with other employees, was stationed to catch the logs as they were lifted from the vat, peeling the bark off and rolling them to the veneer room. If a log was lifted from the vat of a different kind of wood from that being used at the time, it was rolled back into the vat. This duty required the plaintiff to work near the open vat and often at its very edge. The plaintiff, a young man 22 years old, had been in the employ of the company on this work two and a half months. Down to within ten days of his injury the defendant had used a rail as protection, consisting of a heavy 2x6 scantling laid flat and extending 10 or 12 inches above the *171floor. This was not a part of the vat, but a protection. About ten days before the plaintiff's injury this railing had rotted away and had not been replaced at the time of the injury. The president of the defendant company passed by the plaee where the rail had rotted away three or four times a day, and the defendant's foreman testified that he knew that the railing had rotted away several days before the accident. The defendant, however, with full knowledge of the absence of the protection formerly used, continued to require his employees to peel and drag the logs on the narrow platforms, 5 or 6 feet wide, saturated with water, covered with slick bark, and adjoining deep vats filled with boiling water.
While the plaintiff was engaged in peeling and moving the logs on the platform, which that day were poplar and oak, a chestnut log was lifted from the vat, and the plaintiff in the line of his duty put it back into the vat. To do this he struck the axe, which he was furnished with for that purpose, into the end of the log, and in attempting to pull it around to put it back into the vat he slipped on a piece of bark and fell into the vat where the protection had rotted away.
The jury found, upon all the evidence, that the plaintiff was injured by the negligence of the defendant and did not contribute to his own injury, and assessed damages. From this verdict, and judgment thereon, the defendant appealed.
The defendant’s exceptions' 1 and 2 are because the court refused to permit witness to answer certain questions. Without considering these exceptions further, it is sufficient to say that error cannot be assigned for ruling out questions unless it is shown what replies were sought to be elicited, so that the court may see that the appellant was injured by such ruling. Stout v. Turnpike Co., 157 N. C., 366; Knight v. Killebrew, 86 N. C., 402.
The next exception is because the defendant was not allowed to impeach a witness introduced by himself.. Having offered the witness to the court as credible, the defendant could not be permitted to impeach him. It could, however, have shown a different state of facts by another witness. Sawrey v. Murrell, 3 N. C., 397; S. v. Taylor, 88 N. C., 694.
Exceptions 4 and 5 are abandoned. Exceptions 6, 7, 8, 9, 10, and 12 are to the charge; but the instructions excepted to presented merely the well settled rule of the prudent man. The court charged the jury: “Now, this is the test, gentlemen: Would a reasonably prudent man, a reasonably cautious employer of labor,' under these or similar circumstances, having proper regard for the safety of his employees and, to furnish them a safe place in which to work — and that means that regard which an ordinarily prudent man would have furnished under like or similar circumstances — would such a man have maintained this vat without some protection, railing or other protection, around it for the *172safety of tbe employees, wbo bad occasion to go and come around and about it in performing tbe work there ?”
Tbe court also charged tbe jury: “If you find that a reasonably prudent and cautious man would have protected this vat, with some sort of railing or other construction around it, and you are satisfied of that by tbe greater weight of tbe evidence, then it was the duty of this defendant to have done that; and if be failed to do that, such failure-would be an act of negligence upon bis part”; and also, “Tbe burden is upon tbe plaintiff to satisfy you by tbe greater weight of tbe evidence that tbe defendant failed to conform to tbe duty of tbe prudent man in this respect; that is, that tbe defendant failed to construct and maintain its vat in tbe manner which the prudent man would have done wbo was exercising that proper regard, reasonable regard, for tbe safety of bis employees that tbe law requires tbe employer to exercise.”
Tbe facts of this case are almost identical with those in West v. Tanning Co., 154 N. C., 44, in which tbe plaintiff slipped into such a vat of boiling water as this, in a similar plant. It was tbe duty of tbe defendant to furnish tbe plaintiff with a reasonably safe working place, and tbe evidence was proper to be submitted to tbe jury that in not replacing tbe previous guard rail as a protection tbe defendant was guilty of negligence.
We cannot concur with tbe defendant that general custom in tbe use of safety appliances is tbe sole test of negligence. But tbe appliances furnished, methods employed, and places for tbe safety of servants should be such as commend themselves to an ordinarily prudent man. Hornthal v. R. R., 167 N. C., 629; Tate v. Mirror Co., 165 N. C., 280; Ainsley v. Lumber Co., ib., 122.
Tbe charge of tbe court in this and other respects excepted to are approved in tbe cases above cited, and also in Steele v. Grant, 166 N. C., 535; McAtee v. Mfg. Co., ib., 448; Steeley v. Lumber Co., 165 N. C., 27; Reid v. Rees, 155 N. C., 231; Aiken v. Mfg. Co., 146 N. C., 324. There are other exceptions to tbe charge, but we do not think that they require further discussion, as they are covered by tbe general propositions above stated and tbe cases already cited.
There were twenty-four prayers for instruction banded up to tbe judge, and as to one of these, marked 10A, tbe apjDellant contends that it was overlooked by the court. This prayer was, “If tbe jury find that tbe defendant ordered tbe plaintiff not to use tbe axe in moving tbe logs around, but violating bis orders, be used tbe axe, for that purpose and bis disobedience was tbe proximate cause of bis injury, be could not recover.” Without discussing tbe question whether this prayer was overlooked by tbe judge because of tbe manner in which it was placed on bis desk, it is sufficient to say that tbe judge substantially gave that prayer as No. 16 of tbe special instructions, as follows: “If tbe jury *173find that suitable tools and appliances were furnished the plaintiff with which to roll and move the logs, and that the plaintiff failed to use the appliances furnished him, but used an axe, and while using- the axe and attempting to move the logs, the axe pulled out, causing the plaintiff to fall in the vat, he could not recover, and it would be the duty of the jury to answer the first issue ‘No.’ ”
Besides, it has been often held 'that a prayer which concludes as this, “The plaintiff cannot recover,” without applying it to any issue, is defective, and a refusal to give it cannot be assigned as error. Earnhardt v. Clement, 137 N. C., 93; Satterthwaite v. Goodyear, ib., 304; Witsell v. R. R., 120 N. C., 557, and cases there cited.
Nor was it error for the court to refuse to charge the jury that if they believed the evidence, the plaintiff was guilty of contributory negligence. After careful consideration of all the exceptions, we do not find that the defendant sustained prejudice in the trial of this cause.
No error.
