Loring, J.
The facts disclosed by the plaintiff’s evidence were substantially as follows: At about twenty minutes after four o’clock in the afternoon of December 8, 1905, the plaintiff’s testator with some five or seven other men was. at work in a trench removing the debris caused by a blast, when the dynamite in one of *127the holes exploded and caused the injuries here complained of. The blast in question had consisted of nine holes; the explosive used was dynamite, and the dynamite was exploded by a cartridge or an exploder put in the dynamite in each hole. One set of electrical wires was used, which connected with each and all the exploders. The condition of the rock after the accident indicated that all of the nine holes had exploded. As the explosions in all the holes that explode are simultaneous, this is the only way of ascertaining, before the debris is removed, whether it is probable that all the holes have exploded. The plaintiff’s testator was a workman of many years’ experience in blasting; earlier on the same day he had found that the hole next but one to the hole here in question had not exploded, had cut the wires and removed the exploder and the sticks of dynamite originally put in the hole. The foreman of the gang to which the plaintiff’s testator belonged and an engineer (who was assistant to the superintendent of sewers and who had charge of sewer construction work in the defendant city) both testified that before this accident they had had trouble with both kinds of electrical exploders used by the defendant city in setting off dynamite blasts, and the foreman testified that he had told the engineer that he preferred the brand not furnished him. It appeared that the defendant did not furnish this kind of exploder for the blast in question, because it was out of exploders of that brand at the time.
It is manifest that the injuries of the plaintiff’s testator were caused by a danger incident to the work which he was employed to perform. See Allard v. Hildreth, 173 Mass. 26. Although there was evidence that the defendant had had trouble with both brands of exploders used by it, there was no evidence that there were any better exploders in the market than these two, and the preference of the foreman for the other brand when trouble had been had with both did not warrant a finding that the city was negligent in using the brand it furnished for this job. This would be so even if the foreman had testified that the reason for his preference was that exploders of this brand were more certain to explode than those of the other brand, and it is to be noted that the foreman did not so testify.
The foreman in his testimony threw out the suggestion that “The trouble was if it was getting along dusk in the afternoon *128he couldn’t see just as any other man with only one eye. If been another eye perhaps he would have seen this and avoided the accident altogether.” But letting an experienced man continue this work until twenty minutes after four in the afternoon on the eighth day of December, even if he had but one eye, would not warrant a finding of negligence.
