When I was a little thing, I walked on what was then Crowborough Common, and came across, by the side of the railway line, a horribly dangerous looking spot, an iron stained boggy patch, to which I gave a wide berth. It is not marked on modern OS maps, which do show Chalybeate Springs in some places.

Some time later, I read, somewhere I cannot now recall, that there were a number of such places, and they had a name. It could be that they were the remains of bell pits which had not been back filled. I cannot recall the name. I can recall that the writer, remembering her youth (I'm pretty sure it was a woman) emphasised the danger thse places represented.

Does anyone have any idea about the history of this, or is it only in my imagination?

(PS. It was close to Jarvis Brook, but I believe has no connection with treacle mines.)
