in the assignment of the Third Magnesian limestone and all 

 below it to the Potsdam period. 



Summarizing the products of both the First and Second 

 surveys, we find that there were published six volumes, varying 

 in length from ninety-three to over 700 pages, and four pam- 

 phlets, aggregating about fifty pages. The appropriations for 

 these two geological surveys, as given by Broadhead.^ are as 

 follows : 



From 1853 to 1862 



1870 and 1871 



Under acts of 1872, 1873 and 1874

After the stoppage of the apology for a geological survey, 

 for which provision was made under Professor Williams' con- 

 trol, no public geological work was conducted until the year 

 1884, when topographic work was begun in the state by the 

 United States geological survey. This was continued until 

 July, 1889, up to which time about one-third of the state was 

 mapped on sheets of a scale of two miles to the inch, and with 

 contour intervals of fifty feet. In addition Mr. W J McGee 

 was detailed in 1887, by the national survey, to make a brief 

 study of the geology of a portion of Macon county, the results of 



'Missouri Geological Surveys. Historical Memoir. Trans. Acad. Sci. of St. 

 Louis. Vol. IV. Pp. 611-614. 



^ We are informed by Professor Broadhead that the larger part of this unexpended 

 appropriation belonged to the period of the Swallow Survey, though part of it also 

 reverted during the Hager administration of 1870 to 1871.
