Synopsis
Memoir Of The Geological Survey Of The State Of Delaware: Including The Application Of The Geological Observations To Agriculture by James Curtis Booth. This 1841 publication presents a comprehensive account of the geological survey conducted in Delaware during 1837–1838 and outlines Booth’s view that agriculture should be the primary engine of wealth in the state. The work systematically describes the state’s geology, dividing it into four primary rock groups (gneiss, felspathic rocks, limestone, serpentine, with granitic injections) and traces their surface distribution, bearing, dip, and practical uses, including quarrying and construction. It then details the Upper Secondary, Tertiary, and Recent formations, noting the broad succession of clays, sands, marl deposits, and marine fossils, and emphasizing how these deposits influence soil fertility and agricultural practice. The Special Geology portion surveys notable rocks and marls, their locations, and analytical data; the Economical Geology sections discuss soils, manures, lime, marshy soils, and the application of agricultural manures, marl, and green sand to improve productivity. The Arts of Construction and Chemical Arts sections explore building materials, road construction, and industrial uses of Delaware’s mineral resources, including pottery, porcelain, glass, and iron manufacture. The work also includes a discussion of the value of agricultural surveys, soil analysis, and the role of lime and marl in soil improvement.
