工部大学校
Milne was hired by the Meiji government of the Empire of Japan as a foreign advisor and professor of mining and geology at the Imperial College of Engineering in Tokyo from 8 March 1876, where he worked under Henry Dyer and with William Edward Ayrton and John Perry. Partly from a sense of adventure and partly because he suffered from seasickness, he travelled overland across Siberia taking three months to reach Tokyo.
