HISTORICAL MEMOIR 

 By G. C. Broadhead. 



In the year 1849 the Missouri Historical and Philosophical 

 Society authorized a committee, consisting of Falkland H. Mai-- 

 tin, Sol. D. Caruthers, Samuel T. Glover, Wm. G. Minor, and 

 De Witt C. Ballou, to present a memorial to the Legislature. 

 This was presented to the 15th General Assembly of Missouri, 

 <ind setting forth the advantages to be derived from a geological 

 survey of the State and urgently asking liberal appropriations 

 therefor. In their memorial they stated, in detail, what should 

 be required in connection with such surveys, making it incum- 

 bent to show by descriptions and maps all the varied features 

 of surface configuration ; to investigate the causes aftecting 

 health ; the agricultural capacity of the various soils ; to describe 

 the water-courses and water-powers ; to analyze the waters of 

 the springs, and to give full descriptions of the rock formations 

 and analyses of minerals. 



There have been two general geological surveys of the State 

 of Missouri.

 Swallow. Continued in active operation until June, 1861.
