GEOLOGICAL SURVEY. 



We continue our extracts from the State Geological Reports, and here 

 give another portion of the 



REPORT of Bela fluhhard. Assistant Geologist; to Douglass 

 Houghton, State Geologist. 



Sir — In compliance wilh your instructions, entrusting to me the 

 Geological Supervision of the counties of Wayne and Monroe, I com- 

 pleted, late in the season, a detailed examination of those districts, the 

 most prominent results of which are now submitted. It is hardly nec- 

 essary to add, that as the annual reports are designed to embrace only 

 subjects of immediate utility, considerations of a theoretical nature have 

 been avoided. 



WAYNE COUNTY. 



TOPOaRAPHICAL FEATURES. 



Nearly the whole of VVayne county is included within tliat portion of 

 the peninsula constituting its eastern border, in which no considerable 

 prominences occur, and the descent to the coast is gradual and uniform. 

 In this county, consequently, if we except the township in its north-west 

 corner, the general level is varied only by gentle undulations or isolated 

 , sand lidges, forming no continuous ranges and seldom exceeding the 

 relative height of 20 feet. 



The greatest elevation of coast from Milk River Point, on the St. 

 Clair, down to the Rouge, is about 20 feet; from the Rouge to the 

 mouth of the straits 10 feet. 



Along the whole eastern border of the county the altitude attained 

 at distance of six miles from the coast varies but little from 33 t<j 36
