alumina, 13.99, leaving about seven per cent undetermined for want of more 

 material. Some of the tests seemed to indicate titanium in association.* 



The magnetic pebbles as a rule are not so black, and are associated usually 

 with iron gravel, some of which is non-magnetic. 



NOTES ON THE STRATIGRAPHY OP PANOLA COUNTY. 



About four miles southeast of Carthage, on the Allen Baker farm, M. 

 Payne headright, was seen the following section :

SECTION FOUR MILES SOUTHEAST OF CARTHAGE. 



Sand} T soil in cultivated field , 2 feet. 



Drift in pocket, iron gravel, and magnetic pebbles 4 feet. 



Ochreous centres of iron geodes broken by cultivation ... 1 to 6 inches. 



Red and mottled red and gray clay 18 inches to 2 feet. 



3 feet. 



8 inches. 



2 feet. 



Gray clay — plastic, but slightly sandy 



Lignitic clay shale, with plant fossils — very friable 



7. Lignite bed 



On Six Mile Creek, or Cypress Bayou, at the waterline, were seen: 



Laminated siliceous limestone, with plant fossils 

 Massive siliceous limestone 



2 feet. 

 2 feet. 



These had been disturbed by faulting and sliding, and the exposure was 

 small. Observations afterwards made pn the exposure at Grand Bluff fix 

 their stratigraphic position with reference to each other, and their position 

 with reference to the above section to be between Nos. 5 and 6, and belong- 

 ing to the lignitic series. 



On the road from Wood's Postoffice to Carthage, near the M. Payne head- 

 right, was noticed de f . j p red and mottled red and gray clay, corresponding to 

 No. 4 of the section, and denoting former presence of the iron bed above, 

 now eroded down to the clay. 



*The presence of titanium in these sands has since been confirmed.
