The Sun on the Bookcase

Once more the cauldron of the sun
Smears the bookcase with winy red,
And here my page is, and there my bed,
And the apple-tree shadows travel along.
Soon their intangible track will be run,
And dusk grow strong
And they have fled.

Yes: now the boiling ball is gone,
And I have wasted another day....
But wasted--wasted, do I say?
Is it a waste to have imagined one
Beyond the hills there, who, anon,
My great deeds done,
Will be mine alway?
