 Chemist, and R. B. Price, of Brunswick, Mo., Draftsman of the 

 Surveys. Dr. Litton was then and has been nearly ever since 

 Professor of Chemistry in two colleges in St. Louis. He was 

 also previously employed by D. D. Owen as one of his principal 

 assistants in the geological survey of Wisconsin, Iowa and Min- 

 nesota. 



Subsequently B. F. Shumard, M.D. — then of Louisville, Ky.,. 

 and a native of Pennsylvania — was appointed Palaeontologist and 

 Assistant Geologist. Dr. S. had previously occupied the posi-

During May and June, 1853, Prof. Swallow made surveys in 

 the counties of Howard and Boone. In June Dr. Litton visited 

 important mines in Southeast Missouri and made valuable col- 

 lections therefrom. He worked two months in the laboratory, 

 and later in the season he took the field, and, in company with 

 Dr. Shumard, made special examinations of certain mines iu 

 Franklin, Washington, St. Frangois, Madison, Jeflerson, St. Ge-

 structure along the Missouri river from the extreme north-west to 

 Rochport.
