The plaintiff, an employee in the defendant’s talc mine, while working on a platform built in the shaft at the entrance to a drift, was injured by a mass of broken rock, which became detached from the north side of the shaft at a point some twenty-five feet above the platform. He had then been at work in the mine about four weeks, but he had worked there nearly four months -in the preceding year. The shaft was made by taking out a vein of talc, and was entirely excavated at the point in question before the plaintiff’s first employment. The workmen entered and left the mine on the south side of the shaft, the width of which from north to south was about twenty feet. The only light they had was from ordinary lanterns carried with and hung near them; and they could scarcely see the place from which the rock fell, either in passing up and down or from the platform where they worked.
Talc is described in the evidence as a mineral soapy to the touch, and easily dislodged because of its slippery character. A vein of talc is usually separated from the solid rock by a mixture of talc and quartz, the limit of which is easily determined; and safety requires that both the pure talc and the surrounding mixture be entirely taken out. The material which fell upon the plaintiff consisted of this mixture.
The evidence tending to establish the above facts presented a case on which the plaintiff was entitled to go to the jury, and the defendant’s motion for a verdict was properly overruled. It was the duty of the defendant in excavating the shaft to be duly careful to leave the walls in a reasonably safe condition. Union Pacific Ry. Co. v. Jarvis, 3 C. C. A. 433; Western Coal and Mining Co. v. Ingraham, 17 C. C. A. 71. Eisks which ought not to have existed, and which would not have existed but for the master’s negligence, are not included in the risks assumed as ordinarily incident to the employment. Dumas v. Stone, 65 Vt. 442. There was no special assumption of this risk, for it does not appear that the plaintiff knew or ought to have known that the wall had been left in an unnecessarily dangerous condition.
