to the teaching staff of the Department of Mineralogy. Douglass Houghton (A.M. and M.D. Rensselaer Polytechnic Inst. '29) was tendered the position of Professor of Geology and Mineralogy, and also was "charged with the subjects of Chemistry and Pharmacy till the Regents take further order in relation thereto" (R.P., 1837-64, p. 100). Because of his training and experience the selection of Houghton was very fitting. After his college training he had accompanied Schoolcraft on an expedition to the copper-mining region of Lake Superior. He had written a "Report on the Existence of Deposits of Copper in the Geological Basin of Lake Superior," which had attracted so much attention that in 1837 he was appointed state geologist.
His appointment as Professor carried with it a salary of $1,500 a year, but it was stipulated that the salary was not to begin until he entered upon his duties as a teacher, and as circumstances prevented him from assuming regular duties in Ann Arbor, he never received any salary from the University. It is reported, however, that he did give a brief course of lectures (Farrand, p. 55), and some confirmation of this statement may be found in the faculty report for 1842 (Sen. Doc., 1843, No. 5, app., p. 84). Although in the first Catalogues, 1843-44 and 1844-45, mineralogy was scheduled for the third term of the junior year and Houghton was listed as Professor of Chemistry, Mineralogy, and Geology, there is a lack of evidence in reports of work completed that the mineralogy course was actually given.
While engaged on a geological survey of the Upper Penninsula, Houghton lost his life in a storm on Lake Superior, October 13, 1845. Although his association with the University was all too brief, his influence was enduring, as his collections of mineralogical and geological specimens came into possession of the University through an act of the legislature passed in 1846.
Silas Hamilton Douglass (A.M. hon. Vermont '47), who had formerly accompanied Houghton on his geological surveys of Michigan and had served for one year as his assistant, especially in chemistry, was placed in charge of the department after Houghton's death in 1845. He was a man of unusual ability, and during his thirty-three years with the University he was called upon to serve in many and varied capacities, as indicated by the titles he held at different times. After serving as a lecturer on chemistry and geology in 1845-46 he held the following professorships: chemistry and geology, 1846-47; chemistry, mineralogy, and geology, 1847-50; chemistry, pharmacy, medical jurisprudence, geology, and mineralogy, 1850-55; chemistry, mineralogy, pharmacy, and toxicology, 1855-70; chemistry and mineralogy, 1870-74; chemistry, 1874-75; and metallurgy and chemical technology, 1875-77. Also, he was Director of the Chemical Laboratory, 1870-77.
Thus it appears that the first actual systematic instruction given in mineralogy dates back to 1845, when Silas Douglass was placed in charge of the department. In 1874, largely because of the increasing demands upon his time as the result of the rapid expansion in the field of chemistry, the Regents, at their October meeting, relieved him of some of his responsibilities by voting to drop the word "mineralogy" from his title.
Douglass was followed by Eugene Woldemar Hilgard (Ph.D. Heidelberg '53, LL.D. Michigan '87), who had studied at the Royal Mining School at Freiberg and also at Zurich and Heidelberg. When
