 970.66 square miles, or 10,221,232.4 acres. In addi- 

 tion to the foregoing surveys, thirty "quadrangles" 

 in the Lower Peninsula have been surveyed by the 

 same agency, the manuscript maps of which are 

 on fde in the office of the State Geologist. These 

 quadrangles aggregate approximately 6,600 square 

 miles, or 4,224.000 acres. A similar survey of the 

 Upper Peninsula covers 16,660 square miles, or 

 10,662,400 acres, a manuscript map of which has 

 also been prepared by Leverett. The total of these 

 items is 38,630.66 square miles, or 25,107,622.4 

 acres, which Leverett has mapped thus for the Geo- 

 logical Survey of ]\'richigan. Earlier surveys con- 

 ducted by the State Geological Survey cover Huron, 

 Sanilac, Wayne and Monroe counties; while certain 

 quadrangles have been mapped by the United States 

 Geological Survey.^ (See Fig. 2.) These surveys, 

 it is to be understood, do not primarily relate to the 

 agricultural possibilities of the soil. As yet no sur-
