It is news to me that my "magnum opus" on the Matlock area is to be published in 2014. I have not even started doing the diagrams yet and will need help with them.
Although it will not include an account of Ball Eye, it does give a lot of detail about the sough linking Ball Eye to Matlock Bath, which of course continued into the Fountrabbey Sough system in what Lawrence Hurt called the Matlock Sough.
Together with Andy Hayes, I resurveyed Ball Eye to add more to Hurt's survey but it did not yield anything useful for the Fountrabbey System and we could not get into the Matlock Sough system - it had by then collapsed under Ball Eye Quarry. Unfortunately, we did not then know about the shafts on the sough going towards Upperwood and never even went to look at their surface features - now all destroyed by fluorspar mining.
When it is definite that I am going ahead with the Matlock book, I am hoping to put some requests for help on this website in case anyone has info on some obscure points (such as the above) that have eluded me so far.
