CLASSIFICATION OF UPPER PALA OZOIC ROCKS. 765 
wood limestone appears at the foot of the hill, near railroad level, 
while the first heavy stratum of flint and limestone of the 
so-called ‘‘ Flint Hills” 
forms the brow of the bluff. The fol- 
lowing section of the exposures on the slope and along the road 
up to the Crusher Quarry gives quite accurately the thickness 
of the various strata composing this formation:
