In these dark chambers here what weary days 
I spend, walk up and down as in a maze 
To find the windows.----Only to unclose 
One of these windows will be some relief.--- 
But somehow windows this room hasn’t got, 
Or I can’t find them. Perhaps I’ better not. 
Perhaps the light would be another grief. 
What fresh surprises ther might be, who knows?
