exposures at about the same altitude in an abandoned railway 

 cutting a mile and a half northwest, and in the Bevier road a mile 

 west, of Macon. 



5. Pavsoii Section. 



Feet. 



1. Regularly bedded slightly inagnesian limestone, no fossils 

 observed, about 2J 



2. Calcareo-arenaceous shale, about.. 3 



3. Arenaceous shale, sometimes locally lithiiied into moder- 

 ately firm sandstone, about 6 



The next section observed is in the channel and west bluft' of 

 East Fork, just above the brid^^-e on the Bevier road. It is much 

 obscured by talus, but the various portions exposed at difterent 

 points were readily combined. 



6. Bevier Briilae Section. 



Feet. 



1. Compact limestone, generally pure but sometimes slightly 

 magnesian, containing no good fossils but occasional tra- 

 ces of shells. In one or two heavy ledges 3 



2. Thinly laminated black fissile shale 3 



3. Slope, about i.S 



4. Irregularly bedded knobby limestone with abundant Pro- 

 ducti, etc. 2 



5. Slope to bottom of river channel i 



In descending the river an exposure w'as observed at the bridge 

 on the McGee College road which supplements and corroborates 

 the Patton creek section. It is as follows : 



Feet. 



1. Limestone, heavy-bedded and massive, bluish-gray, gen- 

 erally pure or slightly argillaceous but sometimes magne- 

 sian, with conchoidal fracture; containing no well pre- 

 served fossils but many obscure markings 3 



2. Bright, jet-black shale, thinly and evenly laminated, with 

 nodular concretions, darkest below 5 



3- Coal li 



4. Fire-clay, bluish-gray, tenacious 3 



5. Slope to clay-bed of creek, about 5 



The next noteworthy exposures are on Patton creek, from half 

 a mile to a mile and a half above its confluence with East Fork. 

 A dozen or more exposures were combined to foim the section.
