Picked this up the other day so haven't had a chance to read it yet. Published by Jonathan Cape Limited in 1926. Twelve chapters which include - Avebury: The First Capital of England. The Structure of Archaic England. Mount Silbury. The Long Barrows. Some 400 pages (letterpress on wove paper) thee maps and several B&W illustrations taken from Colt-Hoar's Ancient Wilshire.
Saw another copy recently (cover a bit battered) for the princely sum of £5.99 if anyone's interested.
Quote on page 26: "Hard to tell yet may be told." (Pepys on Stonehenge).
