Length of Moon by Arna Bontemps

Then the golden hour 
Will tick its last 
And the flame will go down in the flower.
A briefer length of moon 
Will mark the sea-line and the yellow dune.
Then we may think of this, yet 
There will be something forgotten
And something we should forget.
It will be like all things we know: .
A stone will fail; a rose is sure to go.
It will be quiet then and we may stay Long at the picket gate
But there will be less to say.
