preliminary. Its aim was to mark down on accurate maps the 

 boundaries of the geological formations, the limits of prairie and 

 timber, mineral localities, and all other matters necessary to form 

 a geographical as well as geological map. Sections were corre- 

 lated and grouped ; minerals, fossils, rocks, ores, and mineral 

 waters collected, also the different kinds of soil. The bluffs along 

 the streams were indicated upon the maps, the height of hills 

 measured above the plains, but no strictly topographical surveys 

 were made. Such surveys as we have described were made in 

 all except thirty-three counties. 



Partial surveys were also made in other counties. 



The survey was sustained by regular annual appropriations 

 made by order of the Legislature. 



The office and headquarters were in rooms of the State Uni- 

 versity at Columbia. 



Although Prof. Swallow was during part of this time Profes- 

 sor in the University, the University had no control over the Sur- 

 vey or its officers, either directly or indirectly. 



Besides paying special attention to geology, the members of 

 the Survey were also requested, when convenient, to make botan- 

 ical collections, also collections in zoology and the various de- 

 partments of natural history, and to obtain all the necessary 

 information towards constructing complete geological as well as 

 geographical maps. 



The chief assistants were appointed and commissioned by the 

 Governor upon the recommendation of the State Geologist. 



The State Geologist received $3,000 per annum, the Assistants 

 from $1,000 to $1,500 per year. 



There were generally two parties in the field, who camped 

 out in tents, the camp equipage, horses, etc., being the property 

 of the State. 



The civil war of 1861 interfered with the progress of the sur- 

 vey, and it was stopped. 



About the year 1S66 the Legislature authorized Prof. Swallow 

 and L. D. Morse to publish the manuscripts of the geological sur- 

 vey, but on account of the expense it was abandoned. 



SECOND GEOLOGICAL SURVEY. 



In 1S70 the Missouri Legislature passed an act organizing a 

 Mining Bureau, to be composed of the Governor and nine mem-
