16. TOBOYNE TOWNSHIP. F\ 359 



The Onondaga group, (V.) 



All the valleys of the township are occupied by the red 

 and variegated shales of this group, the gray calcareous 

 upper beds having been for the most part eroded. Of the 

 latter, however, there is an outcrop about a mile west of 

 New German town where one of its beds has been quarried 

 for lime, on the farm of Mr. Eby, the most westerly point 

 at which they have proved of value. The other portions of 

 the group are also more than usually calcareous, but with 

 this exception what has already been said of the group in 

 Jackson and Madison townships will apply to Toboyne with- 

 out repetition. 



Xo rocks newer than the Onondaga shales now exist in 

 this part of the county, and consequently the geological 

 history of the township ends here. All the higher and 

 newer beds that once existed have been destroyed.
