Abstract

Between 1860 and 1930, the Canada-United States border emerged as a crucial economic boundary. In creating the border, however, Canada and the United States prioritized revenue generation over coherence or uniformity. This priority created an unpredictable barrier for both businesses and individuals. Consuls often focused their attention on understanding the impacts of tariffs, trade volume, and smuggling on transnational commerce. The border’s practical impacts, however, went far deeper. For individuals, the border’s unpredictability shaped everything from how they gave gifts to the ways they supported their families. For businesses, the border impacted profit margins and intellectual property. But it also changed how businesses approached administrative tasks—everything from staff training to who they delegated to fill out paperwork. Although imagined as a federal project, the border’s tolerances for variation ensured that regional and local solutions proliferated. Federal mandates merged with local interests to create an inconsistent barrier of ever-changing heights.

Figure 1. United States Customs Service by Aggregate Compensation, 1860–1880, in Constant 1860 Dollars. Maps created by Benjamin Hoy. The scarcity of information on retail prices has meant that prior to 1914 the Consumer Price Indexes (CPI) for the United States were inconsistent and should be interpreted with caution. This map relies on Ethel Hoover’s Consumer Price Index for 1851 to 1890. The index looked at fifty-eight commodities and used weighted averages based on the “distribution of major groups of family expenditures in 1875.” According to that index, consumer prices shifted heavily across the three time points (1860=100), 1860: 100, 1870: 141, 1880: 110.

Con. Res. 13 Part 2Historical and Comparative Rates of Production, Productivity, and Prices (Washington, DC: Government Printing Office, 1959), 401; Ethel D.

The Conference on Research in Income and Wealth (Princeton, NJ: Princeton University Press, 1960), 141–142. The Customs Service stationed the bulk of its personnel around major port cities, particularly along the eastern seaboard and the St. Lawrence River. It paid far less attention to the trans-Mississippi West. Mapping compensation (rather than personnel) adjusts for the part-time status of employees who appeared on federal paylists and draws more attention to locations where high-ranking civil servants drew larger salaries. The digitized paylists from which this map was generated are available online. The website includes a detailed guide of the data cleaning and mapping process. The map below indicates the aggregate compensation paid at each post. It does not include the often-substantial bonuses that customs agents received.
