One of the hand-haspel's buckets was at the top, the other down below. Jack climbed into the one that was up, and hugged the opposite rope, and by letting it slide through his arms was able to descend smoothly for a short distance: until he relaxed, and the rope slid too fast, and he hugged it tight out of panic, so it burnt him and made him let go, causing the same cycle to repeat, except worse. The only thing that interrupted this round was when, at the halfway mark, the lower bucket came up and caught him under the chin and caused him to let go entirely – which was fine, as he would have been stuck at that point anyway. He dropped, then, with only the empty, ascending bucket as counterweight, and what saved him was that the impact of his chin against same had set it swinging briskly back and forth, its rim biting into the rough wall of the shaft faster and faster as it rose higher and higher, throwing sparks and dislodging fusillades of jagged rock in Jack's direction with every impact, but also slowing his fall with a corresponding series of violent jerks. Jack kept his head down and his kienspan up in case this shaft terminated in water, a possibility he should have considered earlier.
