Moss, that's brilliant. The amount of time and thought! and all your walking through the landscape. I was thinking 'how can I possibly add to this' but I think there's a little something (though you are probably quite aware of them come to think of it). Last year I collected water from the springs around the round hill - I kind of incorporated into my art course. ANYWAY it was your mention of the pucan wylle. I can't remember offhand how I found out where this is- it was probably the 'holy wells of the bristol area' book. Anyway it's about at st711667 to my knowledge. It comes out of a little pipe in a bower made by the hedgerow of the field boundary. And the other day we walked past another which I hadn't seen before - I'm not aware of a name but it deserves one as it has a little bath stone wellhouse, and a trough below. It's marked as a 'spout' on the 1:25K map, it's about st706667.
