The cartoon depicts Joseph Chamberlain in the costume of a well-known advertising character, Sunny Jim; the rhyme is a parody of the jingle associated with Sunny Jim:
High o’er the fence leaps Sunny Jim.
Force is the food that raises him.
The cartoon’s title refers to Chamberlain’s nickname, “Brummagen Joe&rdquo: ‘Brummagen’ was a local name for Birmingham and its residents.
The word ‘stump’ was almost certainly intended as a pun: literally, as in the cartoon, a stump is the part of a tree that is left in the ground after the tree has been felled; figuratively, “going on the stump” refers to a politician who goes about the country making political speeches, as Chamberlain was doing.
