16 PROCEEDINGS OF THE BALTIMORE MEETING 



ica, and Dr. J. S. Xewberry, afterward State Geologist of Ohio and a 

 paleontologist of more than national reputation — all names that will be 

 forever associated with the geology of the ^Mississippi A^alley. 



In 1871 Mr. Broadhead was recalled to Missouri to serve as Assistant 

 State Geologist under Prof. Eaphael Pnmpelly, recently appointed direc- 

 tor of the revived organization. Besides revising his county reports pre- 

 pared under the Swallow regime a dozen years before, he devoted much 

 time to an examination of the Coal Measures of the region. The second 

 half of the Pumpelly volume contains the results of these efforts and com- 

 prises more than 400 pages profusely illustrated. This report was pub- 

 lished in 1873. 



When, in the middle of the year 1873, Professor Pumpelly resigned his 

 post as Director of the Missouri Geological Sun^ey, Mr. Broadhead was 

 unanimously chosen in his place as State Geologist by the Board of IMan- 

 agers. With reduced force and depleted funds he entered on his difficult 

 task. The results of the year and a half of investigation are contained 

 in a sumptuous volume of 800 pages, which amply attests the great vigor 

 with which the work was prosecuted. The State Geologist alone con- 

 tributed 20 chapters to this volume, chiefly detailed reports on the mineral 

 resources of counties. 



As Special Agent of the United States Census Bureau, Mr. Broadhead 

 investigated, in 1881, the building stones of Missouri and Kansas. His 

 painstaking report is contained in volume x of the Bureau's publications 

 issued in 1883. In later years Mr. Broadhead contributed important 

 articles to the reports of the Missouri Geological Survey. Two of these 

 deserve special mention. They are entitled "Coal Measures of Missouri," 

 which is a final revision and summary of his work in this field, and the 

 "Ozark Uplift and the Growth of the Missouri Paleozoic," which is also 

 his last word on this topic. The first of these memoirs appears in volume 

 viii and the second in volume xii of the Keyes reports. In the last men- 

 tioned volume also appears his "Geology of Boone Count}^," which was 

 written especially for the students in geology in the State University, 

 which is located in that county. 



When, in 1887, he was called by the Board of Curators to the Chair of 

 Geology in Missouri University, Professor Broadhead succeeded that ven- 

 erable colleague of David Dale Owen, Dr. J. G. Norwood, who had held 

 the post for 20 years. For a full decade he performed with signal ability 

 the duties imposed by a rapidly expanding institution. Before his retire- 

 ment as professor emeritus, in 1897, interest in earth-study had grown 

 in the university until the work of instruction required the time and 

 efforts of three teachers in place of one. Many of Professor Broadhead's 

 students have attained prominence in their chosen line.
