Wacker and Clemens assemble a wealth of informnation that traces spatial and temporal patterns of agriculture in this very diverse state. Diaries, probate and tax records, store ledgers, and other sources detail cultural and economic factors that interacted with the natural landscape to produce complex patterns of land use. While perhaps of greatest interest to historians and historical geographers interested in teasing out the role of markets in shaping agriculture systems, this book will also informanyone who wants to gain a more nuanced and intimate understanding of life in this region in the eighteenth and early nineteenth centuries. Moreover, the copious documentation in the maps and tabular summaries makes this a unique and valuable source in itself." --Emily W.B.
