MEMORIAL OF G. C. BROADHEAD lo 



Missouri, which post he occupied for two years, or until the close of the 

 war. Two years later he was appointed by President Johnson as Assessor 

 of Internal Revenue for the Fifth District of Missouri. This office he held 

 until 1868, when he resigned to take up duties on the Illinois Geological 

 Survey. In 18 To he is found preparing the mineral exhibits for the 

 St^te of Missouri and for the Smithsonian Institution for the Centen- 

 nial Exposition at Philadelphia. During the exposition he was one of 

 the jurors charged with making awards in the Departments of Geology 

 and Mining. For many years aft^r 1884 Professor Broadhead served as 

 a member on the Missouri River Commission. During a period of five 

 years he was the most active and conscientious member on the Board of 

 Managers of the Bureau of Geology and Mines of Missouri. 



Along with his railroad surveying and construction, Mr. Broadhead 

 found ample time to collect fossils and to study rocks. His geological 

 experience along the line of the Missouri Pacific Railroad from Saint 

 Louis to Kansas City gave him an insight into the broad features of the 

 Stat^, such as no observer had yet attained. These were valuable days 

 in the geological field. Dr. George C. Swallow, then State Geologist of 

 Missouri, was early attracted by the results of Broadhead's work. So 

 pleased was the State Geologist that he at once employed him. in 1857. 

 to assist in making a geological reconnaissance along the line of the 

 Southwestern Branch of the Pacific Railroad, now the 'Trisco** System. 

 Several publications resulted from this work. Later, as Assistant State 

 Geologist, he investigated the mineral resources of several counties, but 

 the formal reports were not completed before the Civil V^'av put an end 

 to all scientific operations. These county reports, six in number, were 

 published thirteen years afterward, when the Geological Survev of the 

 State was revived, under the headship of Professor Raphael Pumpelly. 



In 1868 Mr. Broadhead was appointed by Prof. A. H. AVorthen, of 

 Illinois, Assistant State Geologist of that State. During the two years 

 that he was engaged in this capacity he visited nearly every portion of 

 the State. His concise descriptions of the geological features of nine 

 counties are incorporated in volume vi of the Reports of the Illinois 

 Geological Survey. Those parts of these reports which bear directly on 

 the useful minerals were revised and republished in volume iii of the 

 series entitled "Economical Geology of Illinois."' Associated with Broad- 

 head on the Illinois work were A. H. Worthen, F. B. Meek, then the 

 leading paleontologist in America : Orestes Saint John, formerlv Assist- 

 ant State Geologist of Iowa and foremost authority in this countrv ou 

 fossil fishes: E. T. Cox, afterward for many years State Geologist of 

 Indiana : Leo Lesquereaux, the most distinguished paleobotanist in Amer-
