Abstract
Curt Adolph Netto (German: 1847-1909) came to Japan in 1873 and stayed until 1886 as "Toreign Employee". He worked at the Kosaka Mine as the chief mining geologist and metallurgist for the first four years and then appointed to the first professor of the Mining and Metallurgy of the University of Tokyo. The author found from the application record written in January 1873 by Takato Oshima which submitted to Tomomi Iwakura ambassador plenipotentiary that Oshima invited Netto. Azuma (1974) estimated that Netto went to the Kosaka Mine in November 1873 from Yokohama through Hakodate, Noshiro, and Yoneshiro River by boat. The author thinks Netto went from Yokohama to Kamaishi by boat and then on foot along Morioka through the Tsugaru Road to the Kosaka Mine, based on Netto's fine sketches and geography. One of Netto's "Japanische Kuste Dat. 7. Nov. 73 "was drawn the Kamaishi Bay from the boat. The mining data including the sketches of Netto should be kept systematically as the historical science data in the Early Meiji stages without photograph record, and should be investigated in detail by specialists.
