[2] Attention to Devon hedges as a feature worth investigating was raised by Clement Pike in the 1925 volume of the Transactions of the Devonshire Association.
You are hemmed in by no simple hedge which you could creep through, no mere stone wall which you could vault over, nor by a low earthwork; but you find yourself confronted by a combination of them all.
There is the earthwork, but it is faced and built up with solid masonry: granite blocks of all sizes, some huge, some quite small, and topping this construction is the hedge, which in some cases has grown into big trees.
[2] Historically, the hedges and hedgerow trees were also a useful source of timber and wood, and their foliage was eaten by the enclosed livestock.
[5] The archaeologist Francis Pryor observes: A visitor to Devon and Cornwall cannot fail to be impressed by the massive hedgebanks that so often confine the road into something approaching a ravine or tunnel.
