'Cash Crop' consists of a vitrine filled with little sculptures of fruit and vegetables carved from a variety of natural soaps. These pieces of 'fruit' are accompanied by labels and painted bank notes. The terms appearing on the labels are taken from the language of economic activity. The juxtapositions are both amusing and sharply critical: 'liquid asset' is a grape; 'share market float' is a lotus; 'tax return' is a peanut; 'global liquidity' is a cola nut. In 'Cash Crop', Fiona Hall explores the connections between trade, natural resources and botany. These concerns have been central to Hall's body of work since the 1970s. Soap is destroyed by water: it is ephemeral and changing. Commerce and trade, too, change with the slides in 'global liquidity'. Botany, like trade, is a system: of classification and collection. Botany is a science developed in order to 'collect' the world of nature. Cash Crop is about the exploitation of natural resources for commercial interests and the artifice of classification. Julie Ewington writes, "Sir Joseph Banks created elaborate cabinets for the exploration voyages of James Cook, in which numerous specimens of plants were taken back to England, studied, dissected, analysed and planted. Later, the economic uses of collected plants were investigated, for medicine, cosmetics, prophylactics and profit... Fiona Hall has selectively emphasised the tendency towards conjoined terms in systems of Western classification. This is not a merely whimsical rubbing together of similarities, differences, binaries: it is a purposeful play between different orders of things, set up to embrace, pull apart, to slip and to slide".
