LETTER OF TRANSMITTAL. 



Missouri Bureau of Geology and Mines, 

 Rolla, Mo., December 1, 1922. 



To the President, Governor Arthur M. Hyde, and the Members 

 of the Board of Managers of the Bureau of Geology and 

 Mines : 



Gentlemen: It is my pleasure to transmit herewith a 

 report on the Devonian formations of Missouri by Doctor E. B. 

 Branson, including chapters on the Bailey limestone by V. 0. 

 Tansey and the Little Saline limestone by Grace Anna Stewart. 

 The stratigraphy of the Devonian has not been studied 

 heretofore in any considerable detail and the relation of this 

 series of formations has not been clearly defined up to the present 

 time. 



The work is an important addition to the systematic geology 

 of the State. 



Respectfully submitted, 

 H. A. BUEHLER, 



Director and State Geologist!
