The total thickness of the Eondout and Manlius of this' section 

 was found by careful leveling with due correction for the dip to 

 be 59 feet and 4 inches. In the Mix and O'Eeilly section the 

 Manlius was 30 feet and 2 inches, which, if no change has 

 occurred in that formation, makes the Eondout here 29 feet and 

 2 inches. The Manlius may be thicker here in which case the 

 Eondout is thinner. That the Manlius is not thinner is shown by 

 the exposure of nearly 27 feet in the city quarry [section 4] .
