1892 Map of Hummelstown

A network of nineteenth-century villages such as Union Deposit, Campbelltown, and Grantville is situated along the tributaries of Swatara Creek, illustrating the dense settlement patterns of the Lebanon and Dauphin county borderlands. Notable landmarks like Indiantown Gap and Manada Gap provide natural passage through the ridges, while local institutions such as Walmers Church and the utility-focused Union Waterworks highlight the social and technical infrastructure of the 1890s.
