A chronological account documents the county’s natural history and human settlement, beginning with geology, fossils, and prehistoric sites, then surveying indigenous peoples, early exploration, and territorial conflicts that influenced settlement patterns. It traces the organization and growth of the county and its towns, municipal and commercial development, transportation and freighting, schools, churches, charitable institutions, and civic buildings. The narrative combines official records with biographical sketches, local anecdotes, and numerous illustrations and portraits of residents and landmarks, providing a regional chronicle of political, social, and economic development spanning the nineteenth and early twentieth centuries.
