This section lies below the one at M. B. Alexander's well, but whether it 

 discloses the state of affairs underneath the region in which the well lies can 

 not be corroborated. 



The southern division, or that part of the county lying south of Little 

 Cypress, divides itself naturally into three sections: First, the high plateau- 

 like region extending through the central portion of the county from the 

 western boundary to a few miles east of the town of Marshall and upon 

 which Marshall stands; second, a belt of land lying around the base of this 

 ridge and within a 300 foot contour line, the chief characteristic of which is 

 its dark brown or orange-red sands with their associated giavels and fossil 

 woods; and, third, an area of gray sands and silts lying in a semi-lunar 

 shape along the Louisiana State line, with projecting horns or extensions 

 stretching along the lake region in the north and the Sabine River on the 

 south, and beneath the three hundred foot line. 



To this region belong the bottom lands around these waters as well as a 

 large portion of the Little Cypress bottoms. 



1. The structure of the plateau or ridge of ore bearing country of the 

 county is shown by the following sections to consist of sands, clays, and ore 

 deposits:
