The ore is usually massive and often fine-granular, admixed or 

 otherwise closely associated with iron, and is less often of the 

 gravel and larger concretionary nodular types so characteristic 

 of the Cartersville district and other of the Paleozoic area-de- 

 posits. Of the former occurrence the locality to the northeast 

 of Cohutta Springs, in Murray county, and that of the Drake- 

 town district, in Haralson and Paulding counties, are perhaps 

 the most typical. Near the Tennessee line, in the northeast 

 part of Murray county and 5 to 6 miles northeast of Cohutta 

 Springs, the manganese occurs as small nests or pockets in ex- 

 tensive beds of iron-ore in the Ocoee (pre-Cambrian) quartzites 

 and slates. The manganese is not entirely free from iron, and 

 much of it is a manganiferous iron-ore of apparently homogene- 

 ous composition.

The ore of the Draketown district in Haralson and Pauld- 

 ing counties is either massive or minutely-divided manganese 

 oxide, in a finely-banded quartzite or sandstone intercalated 

 with mica-schist. The siliceous rock is heavily charged with
