“Bibliography of Niter Mining and Gunpowder Manufacture.” Ohio Valley Historical Archaeology 16 (2001):1-128. With D.B. Ball. Despite being among the nation’s earliest significant chemical industries, the mining of niter from caves and rock shelters and processing of saltpeter and the related manufacture of gunpowder during the American Revolution, War of 1812, and Civil War are unappreciated by many historical and industrial archaeologists. Though emphasizing sources relating to the production of black powder, materials relating to guncotton and smokeless powder are also included. This extensively annotated bibliographic listing likely constitutes the most extensive bibliographic listing and sourcebook for these industries currently available and will be of interest to historic and industrial archaeologists, military and chemical historians, historic preservationists, and speleologists.

“The Foley Family and Their Role in Gunpowder Manufacture.” With N.F. Johnson. In Stottman, M.J. and C.D. Hockensmith, “Archaeological Investigations at the 1795 Elijah Foley House, Fayette County, Kentucky,” 268-273. In Current Archaeological Research in Kentucky. Volume Five.  Hockensmith, C.D., C. Carstens, C. Stout, and S.J. Rivers, ed., 265-313. Frankfort, KY: Kentucky Heritage Council, 1999). This paper presents the results of salvage excavations at the Elijah Foley House near Lexington, Kentucky. Foley, an early gunpowder manufacturer, built a two-story brick residence on his property about 1795. The diverse artifact assemblage at this site was representative of the entire occupational span of the house. Although the site had been disturbed by construction activities for a new subdivision, it still provided an excellent assemblage of an early rural farmstead. I assisted with the excavations and contributed a history of the Foley family as a section within the larger article.

Special attention is focused on the early 1800s and the importance of Kentucky saltpeter during the War of 1812, when Kentucky was the most important producer nationally. Production processes, location of saltpeter mining areas, marketing practices and factors, and key players in the Kentucky trade are discussed.

“The Saltpeter Works at Mammoth Cave and the New Madrid Earthquake.”  Filson Club History Quarterly 66 (January, 1992):5-22. With A.I. George.
