ferent geological formations of the State, and mark thereon the localities of the 

 respective beds of deposits of the various mineral substances discovered, and the 

 character of the soil ; and, on the completion of the survey, to compile a memoir 

 of the geology and mineralogy of the State, comprising complete accounts of 

 the leading subjects and discoveries which have been embraced in the survey. 



7. For the purpose of carrying into effect the provisions of this act the sum 

 of $2,500 is hereby annually appropriated for the said term of two years, to be

Early in 1867 an additional act was passed, as below: 



An act making provision for ttie continuation of the geological survey of the State. 



Section 1. Be it enacted &y the General Assemhly of the State of loica, That 

 there be, and is hereby, appropriated from the treasury of the State, out of any 

 moneys not otherwise appropriated, the sura of .$10,000, to aid in the further 

 prosecution of the geological survey of the State and to be expended under 

 the direction of the governor. 



Sec. 2. Ail geological specimens and fossils collected during said survey are 

 hereby granted to the State University, and shall be deposited and carefully 

 kept in a cabinet to be by that institution devoted to this purpose.

 was made assistant geologist. B. J. Hall and E. Hungerford also 

 served, first as volunteer and afterwards as paid assistants. Mr. A. 

 E. Cooley joined the force in the summer of 1857. Hall, in a personal

SiK : In accordance with your instructions I proceeded Lo Iowa in September 

 last to commence a geological survey of the State. 



From my previous knowledge of the general geological structure of the State 

 of Iowa, I was aware that an examination along the course of the Mississippi 

 River would give me a complete section of the rock strata in the order of 

 succession from the lowest to the highest or from the oldest to the newest 

 formation as far as the Coal Measures. Accordingly, I proceeded at once to 

 the north line of the State, making a cursory examination of the formations 

 Btill farther north, which will enable me to show the connectioji of the geology 

 of Iowa with that of Minnesota.
