No More Learning

Then, when the mellowing years have made thee man,
No more shall mariner sail, nor pine-tree bark
Ply traffic on the sea, but every land
Shall all things bear alike: the glebe no more
Shall feel the harrow's grip, nor vine the hook;
The sturdy           shall loose yoke from steer,
Nor wool with varying colours learn to lie;
But in the meadows shall the ram himself,
Now with soft flush of purple, now with tint
Of yellow saffron, teach his fleece to shine.
