thin, not exceeding three inches, and to lie enclosed in a yellow sand. In 

 some parts of this region the yellow ,sand attains a thickness of over forty 

 feet. Where this thick deposit of sand occurs ore is generally absent or ex- 

 ists in the form of a thin gravelly covering lying upon the tops of the ridges. 

 In the western part of the county the laminated ore deposits are not, as a 

 general thing, very thick. On the upper R. Cornelius survey, according to 

 Mr. Tafi's observations, there is a bed having an average thickness of two 

 feet. This bed is disclosed at a depth of fifteen feet in a well boring. On 

 the A. J. Fowler head right another well gives the following section: 



1. White sand ... 2 feet. 



2. Laminated ore 4 feet. 



3. Yellow sand 26 feet. 



4. Black earth 3 feet. 



35 feet. 

 On the same survey this same bed of laminated ore occurs in a cutting on 

 the side of an old road. In this place the section is: 



1. White sand . . 4 feet. 



2. Laminated ore and ferruginous sandstone 4 feet. 



3. Orange yellow clay and sand or clayey sand, hard as a soft sandstone 



In the region extending from Avinger to Hughes' Springs small deposits 

 of laminated ore occur associated with an orange-yellow clayey sand. These 

 deposits overlie and are in direct contact with the orange sand. This same 

 class of ore crops out at various places in the hills on the banks of Turkey 

 Creek, in the Joseph Burleson, Larkin Martin, and W. M. Burrets headrights. 

 It also occurs on the E. A. Merchant headright. 



About three miles west of Hughes' Springs, on the Missouri, Kansas and 

 Texas Railway, laminated ore occurs, thinly bedded and lying among red 

 ferruginous sand and thinly bedded sandstones. This deposit, sand, sand- 

 stone, and ore, is ten feet thick, and directly overlies the laminated red and 

 white clayey sands found underlying so great an extent of the county. 



On the Evan Watson, Jarius Berry, Gideon Story, George W. Davidson 

 and several other headrights laminated ores occur in varying quantities.
