MEMORIAL OF G. C. BROADHEAD 17 



Broadhead^s youth until he entered college was spent chiefly in Saint 

 Charles County. After leaving school and entering on the practice of his 

 profession, he was located at various points along the line of the new 

 Missouri Pacific Eailroad. As construction reached Pleasant Hill, near 

 Kansas City, he made this place his headquarters. Here, in 1864, he 

 married Marion Wallace Wright. Five children were born of this union. 



For a period of 25 years he continued to make Pleasant Hill his home — 

 until he was called to a professorial chair in the State University in 

 Columbia, his wife having died in the meanwhile (N'ovember 24, 1883). 

 In June, 1890, he was married to Victoria Eegina Royall, of Columbia, 

 who survived him. Professor Broadhead, after a brief illness, which did 

 not at first seem to be anything serious, died suddenly on December 12, 

 1912. 



Of Professor Broadhead^s scientific work, two features in particular, 

 leave enduring impress on the consideration of the geology of the con- 

 tinental interior. His differentiation of the Coal Measures of Missouri 

 and Kansas stands today essentially as he clearly demarkated them nearly 

 half a century ago. oST ames change, perhaps, but his subdivisions remain 

 practically undisturbed. They withstand every test and many an attack 

 to break them down without success. The classification thus outlined 

 constitutes an integral part of the standard rock scheme for the Carbonic 

 Period of N"orth America. His second notable achievement of more than 

 local bearing is his establishment of the Ozarkian Series, the great suc- 

 cession of Late Cambric rocks found not only typically developed in Mis- 

 souri, but extended far and wide to the northward in the Upper Missis- 

 sippi Valley. Both of these generalizations hold high rank. They will 

 ever be connected with his name. 



As a man. Professor Broadhead was genial, courteous, and considerate — 

 a thorough Virginian gentleman of the old school. His interests were 

 wide. His detailed knowledge of events and men was astonishing. Few 

 persons in Missouri were so familiar with the ins and outs of local, State, 

 and national politics. He was a mine of valuable information on the 

 early history of the State and the West, and his intimate acquaintance 

 with the historic spots of his State showed clearly how widely and well 

 he had traveled. On local matters relating to geology he was the most 

 helpful man I ever knew. 



My first meeting with Professor Broadhead I well remember. Prior 

 to that time for more than a decade there had been frequent interchange 

 of correspondence. It was when I was working up the paleontology of 

 Missouri for the State Geological Survey. Some little time previously, 

 in going over the literature on the subject, I was suddenly confronted
