The Dascom Greene papers (MC 30) contain student lecture notebooks, and miscellaneous letters received while Greene was an RPI professor. The lectures (1852-1853) cover a variety of civil engineering topics, including strength of materials, surveying, theory of machines, constructions, etc. The miscellaneous letters discuss the U.S. Coast Survey's need for Troy latitude observations (1871-1874), and the chronograph which Greene ordered in 1882.
