LITHOGRAPHIC STONE. 165 



greatly in quality within a short distance. The stratum that would furnish 

 good building material at one place might be absolutely worthless for such 

 purposes within a very short distance. A considerable amount of stone has 

 been taken out near the old town of Ben Ficklin, four miles south from San 

 Angelo, and used in the latter place, the public school building there being 

 built out of this material. 



MARBLE. 



The stone called "Texas Marble" is nothing more than a partly meta- 

 morphosed shaly limestone, that is of no value for building purposes except 

 for making lime. There are, however, several good quarries of marble that 

 in beauty will rival the best. The most notable place is a few miles southeast 

 of San Saba, and only a short distance from the Fleming Springs, where 

 there is sufficient water to run machinery for the purpose of manufacturing 

 the marble. The marble in this vicinity has several colors, ranging from 

 pure white to shades of red or flesh-colored. These beds are at the base of 

 the Carboniferous or top of the Silurian. 



Another locality where the marble has been quarried is on the north side 

 of Cherokee Creek, six miles below the town of Cherokee, near the farm of 

 Mr. Charles Harris. The quality of this I do not think is as good as that 

 near the town of San Saba. 



It is more than probable that other places may be found where the stone 

 will be equal in quality and abundance to that at these places. 



CLAYS. 



The clays suitable for economic purposes are not abundant, except for the 

 heavier pottery and for brick-making. These are everywhere abundant. 

 The Carboniferous abounds in fire clay of various degrees of purity. Clay 

 for the manufacture of paints can be found in large quantities and of various 

 colors. The localities where this kind of material can be found are too 

 numerous to be mentioned. 



There is not a town in the entire district examined where good clays for 

 making brick cannot be readily obtained in its immediate vicinity. I have 

 not seen any of the finer clays, yet they might occur in many places. 



LITHOGRAPHIC STONE. 



The lithographic stone occurs in a thin bed near the base of the Carbonifer- 

 ous formation. It has a general uniformity of stratification and texture. It was 

 first seen in Hill's pasture, just east of the Sulphur Springs on the Colorado, 

 20 miles west of Lampasas. It was also traced along the outcrop for many 

 miles in different localities. It was again seen in Ramsey's pasture, on the
