Question

Along the reaches of the street Held in a lunar synthesis, Whispering lunar incantations Dissolve the floors of memory And all its clear relations, Its divisions and precisions, Every street-lamp that I pass Beats like a fatalistic drum, And through the spaces of the dark Midnight shakes the memory As a madman shakes a dead geranium.
