Island. The northern boundary extends from this point across to Lime Kiln Point on  
Bois Blanc Island and then along the ordinary high-water mark of the southern shore  
until it intersects the eastern boundary at 84 degrees 30'W longitude. The southern  
boundary shall start at the intersection of the western boundary with the southern  
peninsula, 84 degrees 56'22"W longitude, and extends generally eastward along  
the ordinary high-water mark to a point where the eastern boundary intersects the  
southern peninsula, 84 degrees 30'W longitude, Cheboygan, Emmet, and Mackinac  
counties, Michigan, which area contains 148 square miles, more or less.
