RELATIONS OF THE TOPOGRAPHY TO THE GEOLOGY OF THE REGION. 



The topography of all countries is chiefly dependent upon the na- 

 ture of the geological formations immediately underlying the surface. 

 This is markedly so in Central Wisconsin. The rock systems of this 

 portion of the state are altogether Arch^an and Lower Silurian; the 

 former consisting of gneisses, granites and schists, with other crys- 

 talline rocks, the latter of a series of alternating sandstones and lime-'
