I think any poet has to love drystone walls, those beautiful boundaries that snake across the fields and hills of our Cotswolds and north country like lines of some forgotten script. This is one of the best poems about them I know.

Wall

The wall walks the fell –
Grey millipede on slow
Stone hooves;
Its slack back hollowed
At gulleys and grooves,
Or shouldering over
Old boulders
Too big to be rolled away.
Fallen fragments
Of the high crags
Crawl in the walk of the wall.

A dry-stone wall Is a wall and a wall,
Leaning together
(Cumberland-and-Westmorland
Champion wrestlers),
Greening and weathering,
Flank by flank,
With filling of rubble
Between the two –
A double-rank
Stone dyke:
Flags and through-
stones jutting out sideways,
Like the steps of a stile.

A wall walks slowly,
At each give of the ground,
Each creak of the rock’s ribs,
It puts its foot gingerly,
Arches its hog-holes,
Lets cobble and knee-joint
Settle and grip.
As the slipping fellside
Erodes and drifts,
The wall shifts with it,
Is always on the move.

They built a wall slowly,
A day a week;
Built it to stand,
But not stand still.
They built a wall to walk.
