Issues of 3rd Stone for free Download

A project I've been working on for a while is to scan and make available PDF versions of 3rd Stone magazine, the renowned 'earth mysteries' magazine that closed in 2003. So far I have digitised six issues. The scans start with 17,18,19 and 20 (previous numbers to this were Gloucestershire Earth Mysteries and I don't have copies - if you do and would like to help scan them then please let me know).
As a tribute to the late Aubrey Burl I have skipped forward to make available Issue 30 from 1995 which has some very interesting articles in.
