Scope and Contents: Karl Culmann, a German engineer, traveled through the United States and England, 1848-50, keeping a journal of his observations. Culmann gave particular attention to American bridges, canals, water-works, industrial machinery, steamboats, and other innovations. In 1973, Max Steinhaus of Beverly Hills, Calif., gave to the Survey his translation of passages of Culmann's journal relating to Cairo, St. Louis, Joliet, Chicago, and the Illinois-Michigan canal. The journal is housed in the Library of the Swiss Federal Institute of Technology, Zurich, Switzerland.
