Opinion by
Mr. Justice Stewart,It is only necessary to refer to such facts in the case as are pertinent to the particular ruling of the court here assigned us error. Plaintiff was engaged along with other workmen in taking down what is known as a head-house, a structure built over a mine shaft. To accomplish this work a gin-pole was employed, by means of which, with the necessary ropes and pulleys, the material of the structure, as it was separated from the building, was lowered to the ground. This pole was about sixty feet in length, and was supported by four guy ropes attached to the top and securely fastened at the other ends. The foot of the pole rested on timbers placed at a considerable elevation, and, as plaintiff was the pole runner, his place was on these timbers, or platform, at the foot of the pole. While a load of material from the head-house was being lowered, and when within a few feet of the ground, the appliance carrying the load from some cause gave way. The witnesses for the plaintiff attributed the mishap to the breaking of the pole; those for the defendant to the breaking of the hook at the top of the pole, by which one of the guy ropes, bearing in this instance the strain of the load, was attached to the pole. The former ascribed the breaking of the pole to its insufficiency because of decay in certain parts ; the latter to the circumstance that in falling, after becoming detached from the guy. it struck against what is called a cap, and thus *348broke. The plaintiff was not struck by the pole; his injuries were received by being thrown from the platform on which he stood by certain ropes in which he became entangled, and which must have carried with them to some extent the force of the falling pole or that of the falling load. Immediately before the accident, and while the load was being lowered, the pole was seen by the plaintiff and- other workmen to bend or buckle, and the danger of the pole breaking was spoken of between them. Both plaintiff and these workmen had seen the pole before it was put in place, and had noticed season checks in it, which made them question its sufficiency for the work. Notwithstanding what plaintiff saw as to the bending of the pole, and notwithstanding one of his fellow workmen had called to him of the danger, he continued at his place at the foot of the pole after he had ample opportunity to get away. The learned trial judge, on this state of the evidence, gave binding instructions for the defendant, on the ground that plaintiff was chargeable with contributory negligence in remaining on the platform on which the pole rested with these indications of danger present. This was error. If the contention of the defendant as to the cause of the appliance giving way was correct — and that was a question of fact exclusively for the jury — then the condition of the pole, and the plaintiff’s knowledge of its condition, did not enter into the question of his negligence, and could not be considered. These were elements in the case only in the event of a finding that the collapse of the appliance was occasioned by a defective pole. If occasioned by the breaking of the hook, defendant’s contention was that it was absolved from all liability, because such a break could not reasonably have been anticipated. If such circumstance was sufficient to excuse the defendant, it could hardly be used to convict the plaintiff. The logic that would exempt the one from liability would necessarily acquit the other of negligence. The error on the part of the court was in assuming a fact in regard to which there was conflicting evidence. ¥e are not to be understood as saying as matter of law that the plaintiff would be chargeable with contributory negligence, even if the fact were found that the breaking of the pole caused the collapse. All we decide is that so long as the cause of the collapse was *349undetermined by the jury, the question of plaintiff’s contributory negligence was an open one, and could not be determined by the court. The case required a submission to the jury.
The judgment is reversed and a venire facias de novo awarded.
