The milestone by the rabbit-burrow Thomas Hardy

In my loamy nook
As I dig my hole
I observe men look
At a stone, and sigh
As they pass it by
To some far goal.

Something it says
To their glancing eyes
That must distress
The frail and lame,
And the strong of frame
Gladden or surprise.

Do signs on its face
Declare how far
Feet have to trace
Before they gain
Some blest champaign
Where no gins are?
