Answer:
the three lines from the second line describes an allusion
Step-by-step explanation:
my reason being that allusion is an expression designed to call something to mind without mentioning it explicitly; an indirect or passing reference or can also be defined when a piece of writing tries to hint at a person, place, thing, literature, or art. An allusion is when we hint at something and expect the other person to understand what we are referencing.
though I've not read the poem but I can understand that the poet used the pots marmalade the tea, amongs the proclain, to describe people who will talk about him and the person he is addressing.
