Besides noting the geology, the members of the survey were ex 

 pected, when convenient, to make botanical and zoological collections. 

 There were, as a rule, two parties in the field, with camp equipage, 

 horses, etc., the property of the State. The office and headquarters of 

 the survey were in rooms of the State University at Columbia. 



Concerning the work of this survey Winslow remarks : 



Keviewing briefly this worli of the geological survey, we must recognize as 

 remarljabie aud excellent the clussiflcatioii of the rocks which are iuvolved, 

 as well as the general accuracy with which the distribution of the formations 

 was defined, especially when the short time is considered. Under the control 

 of Hall's new c!:issitication and nomenclature published in 1S43, though un- 

 doubtedly assisted, yet not mislead by Owen's results, Swallow and his assist- 

 ant established a table of formations and outlined a geographical map of the 

 State, which remains to this date unchanged in its main features. 



The law required that the collections should be made in triplicate, 

 one set of which should go to the State University, one to the city of 

 St. Louis, and one to be deposited in some convenient room in the 

 capitol. The Civil War interfered and the collections, though made, 

 were not distributed, the specimens for the most part remaining in 

 boxes until 188-i, when they were unpacked and partly arranged in 

 the museum of the State University. 



Expenses. — The total cost of the survey during the nine years of 

 its existence was $105,000. 



Publications. — Five reports of progress were issued, dated 1853, 

 1854, 1856, 1859, and 18C0, respectively. Of these only the second, 

 comprising 447 pages, contained anything of geological importance, 

 and is the one commonly known as Swallow's report on the geology 

 of Missouri. The others are all brief and partly administrative. 

 The annual reports were distributed through the members of the 

 legislature and by the geologist. 



SECOND SURVEY UNDER ALBERT D. HAGER, 1870-1871. 



Organization. — The survey under Professor Swallow came to an 

 end, as noted, in 1862, owing to the disorganized condition of 

 the country caused by the Civil War. The matter was not, how- 

 ever, long allowed to remain dormant, and even before the close of 

 the war a James McKenzie presented a petition to the legislature, 

 the object of which was to secure the publication of information 

 concerning the resources of the State for foreign distribution. 



In the report of the corresponding secretar}^ of the board of 

 agriculture for 1865, the importance of a scientific survey was dwelt 

 on, but no definite recommendations made. In th.e report of the secre- 

 tary of the same organization, for 1866, the need of geological work 

 again found expression, and at the meeting of the board of agri-
