Tamar's manure canal returns to nature

Gunnislake, Tamar Valley Barges that carried coal, corn, manure, granite, bricks and lime had to be hauled manually upstream against the current

From the hilltop railway station, rain clouds veil sight of Dartmoor and, in nearby Stony Lane, run-off flows between shoals of sodden beech leaves. Down this sunken way towards the river, ferns, mosses and pennywort show green under the tangle of fading bramble, yellow-leafed hazel and bare sycamore; the enclosing hedge-banks frame occasional glimpses across the valley where steep woodland engulfs river-cliffs and pinnacles like Chimney Rock.

Sound of water roaring over the weir carries uphill and becomes even louder below Hatches Green, where tennis court and football pitch in King George's Field are overlooked by the orange and dark green deciduous and coniferous woods opposite - once part of the Duke of Bedford's estate.
