...an author called R. Hippi(e)sley Cox? Last night I was given a copy of his "Where Green Roads Meet..... A Guide to Avebury" Published 1929 by Swindon Press. Foreword by Lord Avebury. Loads of descriptions of green roads, barrows and earthworks in the area, some of which I've never heard of.
In the forward (Rev F.W.Clifford) It says that this book is "An expansion of Chap 1 of The Green Roads of England" and that the present book is long out of print. The author must have died some time previously as his widow hopes that a " Fellowship of the green roads" might be inaugurated in his memory.
Only a small book, 55p, but full of detail, maps and some line drawings and may take some time to take in fully.
