This highly specialized geological treatise is a detailed analysis of soil and subsoil composition near Franzenshütte (a historic location in the Governorate of Livonia) north of Dorpat (modern Tartu, Estonia). Published in 1886 by the local printer H. Laakmann, it exemplifies the precise, local-focused natural science studies conducted in the Baltic provinces of the Russian Empire. The author, Carl Schmidt, was likely a geologist or naturalist affiliated with the renowned University of Dorpat, a major German-speaking academic center. The work contributes to the understanding of Devonian period detritus in the Embach River region. A copy bearing the author's autograph adds significant provenance, transforming this scientific offprint into a unique personal artifact from the era of 19th-century German-Baltic scholarship.
