A fund-raising proposal for the national testimonial to Rowland Hill
-- one penny added to the postage, for a period of one week.
Is this the beginning of semi-postal stamps? A similar concept
had been noted in The

transaction: "if only the value of a single postage stamp be
contributed by every person who has experienced the advantage" of
penny postage.
