tile, etc., and others which from their refractory character are well 

 adapted for the manufacture of charcoal furnaces, and possibly of sewer 

 pipe. 



The Fayette Beds, as was stated in their description in the First An- 

 nual Report, contain beds of light colored clays, many of which are 

 pure white. These beds of clay not only underlie and overlie the mid- 

 dle beds of Fayette Sands, but are also found interbedded with that 

 Series. The excellent qualities of these clays were first stated by Dr. 

 W. P. Riddell, of the First Geological Survey of Texas under Dr. Shu- 

 mard. His specimens were obtained from the Yegua, in Washington 

 County, and in the vicinity of Hempstead. Since that time many an- 

 alyses have been made of clays of various portions of these beds, and 

 while some of them are too high in alkalies or fusible constituents, oth- 

 ers are well suited to the manufacture of all grades of earthen ware be- 

 low that of porcelain, or French china as it is called. Clays of this 

 character have been secured in various localities from Angelina to and 

 below Fayette County. 



There are beds in the Fayette Sands that will be of value in glass 

 making. Some of the beds are composed of clear angular quartz 

 grains without tinge of iron, having only an occasional grain of rounded 

 red or black quartz. 



In the Timber Belt Beds there are other clays and sands well suited 

 to the manufacture of earthenware and glass. Most of the beds of pot- 

 tery clays of this Division examined so far in Eastern Texas are, how- 

 ever, only suited for the coarser grades of earthenware, but in Grimes 

 and Robertson counties (and possibly in others as well) clays of higher 

 grade are found. 



In Robertson County, not far from the town of Mexia, there is a de- 

 posit of sandy clay which is readily separated by washing into a kaolin 

 of excellent quality and a perfectly pure quartz sand. This kaolin has 

 been tested practically and produces a good porcelain. 



Potteries have been erected in various parts of the State within the 

 limits of the Fayette and Timber Belt beds for the manufacture of com- 

 mon earthenware, flower pots, etc., and several are now in successful 

 operation. Among localities of potteries may be mentioned Lavernia, 

 Wilson County; Athens, Henderson County; Kosse, Limestone County; 

 Burton, Washington County, and othera
