While driving out a fid hook in a binding chain on a load of logs, plaintiff’s intestate was caught by the logs, which fell and so severely injured him that he died within two days.' The logs were loaded on a sled, and the unloading gang consisted of four men, including Olson. The landing gang started to break a certain load, which sagged out on the side over the end of the front bunk. This sagging and the logs on the top of the chain made the front wrapping chain, which was between three and four feet from the front end, fit rather tight around the load. The fid hook which held the front binding chain was about six feet above the ground on the right side of the load, and pointed toward the rear end. The rear chain was loosened by Cameron, whereupon Wanski started to knock the front fid hook loose with an axe. Wanski, taking a position opposite to the fid hook and about three feet from the front end of the load, struck the hook several times; but it did not release. After Wanski failed to loosen the fid hook, he handed the axe to Olson. The axe was a double-bitted one, with a handle about three feet in length.

Olson assumed about the same position that had been occupied by Wanski, made necessary by the fact that the fid hook pointed towards the rear end of the load. Olson’s back was toward the front end of the load, and after he struck the first blow he went up to see if the hook had moved. It had not moved, and he tried to straighten it a little, so as to hit it more squarely. He then struck the shank of the hook a second time without effect. He then looked at the position of the hook a second time, and struck the final blow. The chain was then about an inch and a half from the point of the hook. When the final blow was struck, the fid hook suddenly and unexpectedly broke, allowing the logs to come down rapidly with*27out any warning. He tried to run away from tbe side and to tbe front end of the load, making an angle of about forty-five degrees to tbe general direction of tbe load, but was caught by the logs about eight feet from tbe side of tbe load. A number of logs rolled upon bis body, crushing his bones and so seriously maiming him that be died two days later. When he was picked up, bis bead was found to the front of the load.

The negligence relied on consisted in furnishing a defective fid hook. It was clearly established that tbe fid book broke, and the •evidence fairly tended to show that the logs were released as a result of the break, and that the breaking of the hook was the proximate cause of the injury. The fid hook was made of steel, about •one-half of an inch thick by nine inches long. The shank was one inch wide at the lower end or point, and one and a half inches wide at tbe hook end. Tbe point of tbe book was two and three-quarter inches long and the opening, into which a link of the binding chain was intended to fit, was three-quarters of an inch wide at the lower •end and about one-half inch at the upper end. Tbe width of the book at tbe upper end, at tbe turn or bend, was one and one-eigbtb inches. On the inside of the turn there was a flaw or opening extending about three thirty-seconds of an inch deep and about five-sixteenths of an inch in length, and at the outside of the curve the steel was only one-quarter of an inch thick. The hook broke off at this point in line with tbe flaw.

1. It was tbe opinion of the expert witnesses that the flaw occurred in the making of the book,- that it was in that part where the greatest strain came, in the use of the chain, and that the defect would have been discernible on inspection before it broke. Although =some of these witnesses were not very positive in cross-examination that tbe wearing of the chain might not have tended to cover up tbe flaw, the.testimony as a whole was for the consideration of tbe jury. 'The strain upon such books is very great, and their use is attended with danger. The rule is that the master is required to exercise reasonable diligence in the. examination and supervision of such .appliances, and the measure of care and diligence must be proportioned to tbe risk and danger to be apprehended. Moon v. North*28ern Pacific R. Co. 46 Minn. 106, 48 N. W. 619, 24 Am. St. 194; Thompson v. Great Northern Ry. Co. 79 Minn. 291, 82 N. W. 631; Patterson v. Melchior, 106 Minn. 431, 119 N. W. 402. We-consider the evidence sufficient, if accepted by the jury, to warrant them in finding that the defect was of such a character as to require the master to discard the hook upon the discovery of its condition, and also that the breaking of the hook was the proximate cause-of the accident.

2. Considering the position of the fid hook and the character of the implement furnished by the master, it was a question for the-jury whether Olson was guilty of contributory negligence or assumed the risk. Orcutt v. J. Neils Lumber Co. 113 Minn. 331, 131 N. W. 464.

We discover no errors in the instructions, and under the circumstances the verdict was not excessive.

Affirmed.
