could or did see or ascertain that the step was defective or that it was loose and "turned in the groove." The plaintiff did not fall because the step broke but because it tilted. The witness Steenerson testified that when he picked up the ladder after the accident had happened he grabbed ahold of it "by one step up towards the top" and that he found it was loose; that he "wouldn't say it was so loose you could shake it" but it was loose so you could tilt it back and forth (and he demonstrated to the jury what he meant by this). The step was still in place and it was only after he took ahold of it that he found it would tip, but thatin that they furnished the plaintiff, Frank Olson, who was a gratuitous employee of Kem Temple, with this long, fourteen foot stepladder which was in an unsafe and defective condition at the time they furnished the stepladder to the plaintiff and that they had knowledge of the fact that it was in a defective and unsafe condition for a long time prior to the date of the accident in question. The testimony further shows that they had knowledge of the fact that such stepladder was a second hand stepladder when they received it; that it had been in their possession for at least fifteen years prior to the accident, during which time it had become out of repair, and that it had been repaired at least once prior
