REPORT OF THE STATE GEOLOGIST. 



To His Excellency Moses Wisner, 



Governor of the State of Michigan : 



I have the honor to submit herewith, the Eeport required of 

 me by the terms of the Legislative act, approved February 15, 

 1859, and entitled " An act to finish the Geological Survey of 

 the State." This Eeport is intended to set forth the progress 

 of the geological survey during the years 1859 and 1860. 



Allow me, in communicating this Eeport, to acknowledge the 

 many personal kindnesses received at your hands, and the ap- 

 preciative interest which you have always manifested in the 

 progress of the work. Whatever useful results may be here 

 embodied, are due in no small degree to your connexion with 

 the origin and energetic prosecution of the survey. 

 I have the honor to be, 



Tour most obedient servant, 

 A. WINCHELL, 



State Geologist. 

 Ann Arbor, December 31, 1860.
