The plaintiff conceded at the trial that there was no defect in the machine upon which he was at work when he was injured, and the third count only of his declaration was submitted to the jury. The defendant’s exceptions present the question whether the plaintiff was bound to examine and ascertain what was underneath the table of the machine before putting his hand there, and whether a verdict ought to have been ordered for the defendant. This depends upon whether the jury had a right upon the evidence to find that the defendant was negligent on the ground that it did not give to the plaintiff sufficient instructions or warnings of the dangers which caused his injuries.
The plaintiff’s contention was that he put his hand under the table to pull out the box of shavings, which he had been told to do; that by reason of the corner of the box having been knocked off, leaving a hole there, his hand went in farther than it otherwise would have done, and was caught in that part of the saw which was underneath the table. He testified that he did not know that the saw went underneath the table or that there was anything there to cut his hand, and that he had not been told to stop the machine before pulling out the box; and he said that he had repeatedly pulled out the box in the same way while the machine was in motion, in the presence of St. Pierre, who gave or caused to be given to him whatever instructions he received, and that he had not been told by any one that there were saws projecting under the table or that there was any danger in doing as he did on this occasion.
It is difficult to say that the plaintiff’s injury did not come from an obvious risk of his employment. The saws projected a little above the surface of the table, and did their work by revolving. It seems to be manifest that they must also project for a greater or less distance underneath the table. And the risk of putting one’s hand within the reach of such saws, when they are known to be in motion, is certainly an obvious one. Stuart v. West End Street Railway, 163 Mass. 391. It is not material that the plaintiff did not in fact know of this particular danger when he entered the defendant’s employ if, by such ex-*289animation as he readily could make, he would have learned of its existence. McCafferty v. Lewando’s French Dyeing & Cleansing Co. 194 Mass. 412. Gleason v. Smith, 172 Mass. 50, 52. Mutter v. Lawrence Manuf. Co. 195 Mass. 517. McKenna v. Gould Wire Cord Co. 197 Mass. 406. But if we assume that this doctrine would not apply to the plaintiff by reason of his comparative youth and inexperience, and of the fact that there was a certain difficulty in seeing the position and arrangement of the saws beneath the table of the machine, as his counsel has earnestly contended (De Costa v. Hargraves Mills, 170 Mass. 375), we are brought to the question of whether it can be said that the defendant ought to have warned him of the real state of affairs and of the danger which was involved therein.
We cannot see any ground for saying that the defendant ought to have supposed that the plaintiff needed such a warning. The arrangement of the saws, the length of the slots through which they passed, the work that they did and the manner in which they did it were such that the defendant would be justified in supposing that any one of average intelligence would see at once that they must protrude below the table even more than they did above it, and in relatively the same places above and below. It is not negligence for an employer to fail to warn a workman of a danger when there is no reason to suppose that there is any need of such warning. Lemoine v. Aldrich, 177 Mass. 89, 91, and cases cited. The plaintiff’s injury was not due to such a peculiar cause, outside of what the defendant had a right to suppose the plaintiff would know about, as was the case in Halley v. Nashua River Paper Co. 202 Mass. 164, and in Grace v. United Society called Shakers, 203 Mass. 355.
But it is contended that the jury could find that the plaintiff was below the average intelligence of people of his age, and so stood in peculiar need of information and warning. Doolan v. Pocasset Manuf. Co. 200 Mass. 200. But the only contention made at the trial was that the jury should find this “ because of his appearance and manner of testifying.” This is far below the evidence in the case just cited. Nor is there any evidence or any contention that the defendant or any one who acted for it had notice of any lack of intelligence in the plaintiff, or any reason *290to apprehend that he was afflicted with a mental deficiency. But without such notice or reasonable ground of apprehension it was of course proper for the defendant to act on the assumption that he had ordinary intelligence. The question still was whether he appeared to be in need of information that he did not receive. Oiriack v. Merchants' Woolen Co. 151 Mass. 152, 157.
It is impossible to avoid the conclusion that the plaintiff’s injury was due to his thrusting his hand under the revolving saw in a manner and to an extent which the defendant was not bound to anticipate or to warn him against. It is not a case in which he was doing just what he had been told to do and in the way that he had been told to do it, as in Byrne v. Learnard, 191 Mass. 269.
Although the defendant has not asked us to order judgment in its favor under St. 1909, c. 236, yet the case comes within the terms of that statute. The order will be
Exceptions sustained and judgment for the defendant.
