when the kiln is "pushed" or raised to the highest stage of heat the lignite is 

 consumed and leaves the brick in a porous condition. By this process the 

 species of earthenware known as terra cotta lumber might also be made from 

 the same materials, and many of the numerous light fire-resisting articles used 

 in architecture made out of materials at present in a useless condition. 



The peculiarities attending the firing of pottery will probably preclude the 

 use of these lignites in that branch of the clay industries until some changes 

 be made in the construction of the kilns commonly used. 



It is probable some of the better grades may be found useful for gas pur- 

 poses, but this is very doubtful in so far as the Harrison County lignites are 

 concerned.

WATER SUPPLY. 



The drainage of the county is divided into a northern and a southern 

 basin, or the drainage area of the Cypress and that of the Sabine. A small 

 portion of the northwestern part of the county is drained by Big # Cypress, 

 and the eastern lowlands belong to the area drained by the Caddo Lake sys- 

 tem. The southern portion is drained by the Sabine River, and the central 

 waters are carried off chiefly by the Little Cypress Creek and thrown into 

 Ferry Lake, near Jefferson. 



The crest line of the central plateau forms the divide between Little Cypress 

 and the Sabine drainage area, and from its summit the streams tributary to 

 these two flow north and south. There are no large streams within the area, 

 and the main tributaries of Sabine and Little Cypress are mostly dry or only 

 a series of pools throughout the greater portion of the year. The principal 

 creeks tributary to the Sabine River are Mason's, Village, Dufford's, Potter's, 

 Eight Mile, and Papaw creeks. On the north side of the central region the 

 creeks flowing into Little Cypress are Watkins', Ray's, Caney, Page, Moccasin,
