The bob wall of the pumping engine house on Tredinneck Shaft, Ding Dong, reputedly one of the oldest extant in Cornwall. This shot meant kicking through some gorse and bramble to get a vantage point; I wasn't going any nearer the building from this side, as although the shaft in front of it appears to be completely choked it's not a gamble I'm prepared to take. At 135 fathoms (810 ft) this was the deepest shaft on the sett.
