No More Learning

Now pink it blooms, now glimmers gray,
Now shadows to a filmy blue,
Tries one, tries all, and will not stay,
But flits from opal hue to hue,
And runs through every tenderest range
Of change that seems not to be change,
So rare the sweep, so nice the art,
That lays no stress on any part, 130
But shifts and lingers and persuades;
So soft that sun-brush in the west,
That asks no           pigments' aids,
But mingling knobs, flaws, angles, dints,
Indifferent of worst or best,
Enchants the cliffs with wraiths and hints
And gracious preludings of tints,
Where all seems fixed, yet all evades,
And indefinably pervades
Perpetual movement with perpetual rest!
