This Friday we will officially launch Trading Consequences this Friday (21st March), with publication of our White Paper and the launch of our visualization and search tools. Ahead of the launch we wanted to give you some idea of what you will be able to access, what you might want to view and what you might want to compare with these new historical research tools. Professor Colin Coates has been exploring the possibilities…Â
The “Trading Consequences� website literally allows us to compare apples and oranges. Both fruits became the objects of substantial international trade in the nineteenth century, as in the right conditions they can remain edible despite being shipped great distances.
They are complementary fruits in many ways, as apples are grown in temperate climates whilst oranges prefer warmer conditions. They may overlap geographically, but typically we associate different parts of the world with each fruit. In the context of the British world, apples grew in the United Kingdom, of course, but they also came from Canada, New Zealand and the United States, among other locations. Oranges from places like Spain, Florida or Latin America entered the United Kingdom in the nineteenth century. The two maps which result from entering “apple� and “orange� into the database show, at a glance, how oranges appeared more often in reference to warmer zones than apples.
The chronological distribution of commodity mentions was roughly similar in both cases. Increased attention from 1880 to 1900 reflects in part the expansion of the documentation in that period, but it likely also reflected growth in trade and consumption. Historian James Murton has pointed out that regular trade in apples developed from Canada to Great Britain in the 1880s, focused primarily in Nova Scotia. On average, one million bushels of apples reached British markets (Murton, 2012).
In contrast, both apples and oranges show sudden spikes in the 1830s, for entirely different reasons. The spike for apples points the researcher to a useful “Report from the Selection Committee on the Fresh Fruit Trade� in 1839. But the mid-1830s spike in oranges points instead to the activities of Orange Lodges in Ireland. The other visualisation shows this anomaly even more clearly, as IRELAND takes on a prominence in related geographical terms in the 1830s that it did not occupy afterwards.
This project entailed teaching computers to read as an historian might, and there are distinct advantages to being able to deal with such a wide range of documentation. However, all historians must be critical of the sources we use. The visualisations in “Trading Consequences� point towards useful sources for further study, and to suggest that historian may wish to consider some regions in their analysis. The importance of the United States in the discussions about apples is noteworthy, for instance.  Australia has a large number of mentions of oranges, though it is important to note that a small city boasts the same name and could account for part of the number. (Interestingly enough, Orange, New South Wales, did not grow many oranges according to the Australian Atlas 2006! But it does have apples.)

The increase in mentions of both apples and oranges from the 1880s on may reflect improving living standards in Britain in that period. Britain’s decision to adopt free trade had led to an increase in a wide variety of imported foodstuffs (Darwin, 2009). As the heightened attention to both apples and oranges probably shows, these fruits were part of that movement.
The “Trading Consequences� visualisations show some instructive comparisons, some that may point to different ways to conceive of trade in these resources, and others which illustrate the care with which researchers should approach results.
