ED’s alternative words in parentheses. I prefer “Spiceless Sepulchre” in Line 8 because it more directly implies death/tomb than “Ceaseless Rosemary”:
Essential Oils – are wrung –
The Attar from the Rose
Be (Is) not expressed by Suns – alone –
It is the gift of Screws –
The General Rose – decay –
But (While) this – in Lady’s Drawer Make Summer –
When the Lady lie
In Ceaseless Rosemary (Spiceless Sepulchre) –
A two-sentence prose interpretation:
Great poems, like attar from the rose, are not composed by inspiration alone; they are the gift of pain and toil.
Ordinary poems die young, but great poems shed warm light when their poet lies in eternal sleep.
‘Essential Oils’ is probably about ED’s favorite poet, Elizabeth Barrett Browning, who died in 1861, two years before ED copies this poem into Fascicle 34.
