AT A CRITICAL JUNCTURE in part one of Harriet Martineau's Berkeley the Banker, the fourteenth novel in her Illustrations of Political Economy series, there is a run on a country bank. The run is precipitated by a casual exchange in a local shop during which Mrs. Millar, the confectioner, is given a five-pound note to change. Her reply “Oh, I cant change that note [sic]” is misunderstood by others in the shop to mean that she is refusing to honor a particular bank's note while, in fact, she is simply not able to make change (169). The panic that ensues ruins Mr. Berkeley, the country bank's proprietor, and serves the novel's aim of demonstrating the precariousness of paper currency unbacked by the gold standard. In describing this incident, as well as through various characters' periodic lectures, the novel argues that only a gold standard could have prevented a calamity such as the bank run. Under a gold standard, citizens of the town of Haleham never could have misinterpreted Mrs. Millar's remarks–they would have known that the note must be honored and that, therefore, the confectioner merely lacked the correct change. Under a gold standard, in other words, the meaning of paper currency is not open to misinterpretation; its value is fully known and stable. Martineau may be convinced of the gold standard's ability to scuttle the dangers of textual ambiguity, but this moment also exposes the challenge of regulating the circulation and proliferation of meaning. The meaning of a speech act and the value of a banknote are both revealed as unstable and difficult, perhaps impossible, to regulate or manage.
