180 THE IRON ORE DISTRICT OF EAST TEXAS. 



in Cass County extend westerly into Morris, and in the immediate vicinity of 

 the town of Daingerfield. The Daingerfield deposits occur on the Henry 

 Proctor headright, immediately underlying the iron ore deposits of that 

 neighborhood, and a short distance west of the town, and appear in the form 

 of a greensand in a well dug some years ago. On the face of the hill the 

 same deposit appears as a soft yellowish green sandstone. This deposit, No. 

 2 of general section on page 178, has a thickness of about twenty feet. These 

 greensands can scarcely be utilized as fertilizers, as they only contain 0.4 

 per cent of soda and potash and 0.7 per cent of phosphoric acid, with a small 

 proportion of lime In the event of the overlying iron ore being utilized 

 these greensands will be easily obtained for any purposes to which they may 

 be suited. 



LIGNITES. 



Deposits of lignite are reported as existing along the banks of Sulphur 

 Pork on the northern boundary of the county, and at various other places 

 lying north of Daingerfield. These have not yet been visited and examined. 



On the Jonathan N. Bohonan headright, about five and a half miles south 

 of Daingerfield, there are several exposures of a thin seam of lignite. At Mr. 

 S. H. Pruitt's house an attempt has been made to develop this vein, and an 

 opening has been made with a view to mining the lignite for local use. The 

 vein at this place is only fifteen inches thick, and dips a few degrees south of 

 east, and according to Mr. Pruitt, at the rate of one inch in three feet. 



A section of the opening at this place shows the following: 



1. Yellow sand 7 feet. 



2. Lignite ' 1 foot 3 inches. 



3. Black or dark blue stratified s^ndy clay, mixed with lignitic matter, 



visible 5 feet 



The lignite at this place, although reported as being of a fair quality, can 

 not be worked. 



The following is an analysis of the lignite: 



Moisture 4 . 45 



Volatile matter 52 . 05 



Fixed carbon , 15.15 



Ash 28 . 35

 CLAYS. 

 Unless the dark blue clay associated with the lignitic beds can be utilized, 

 there are no clays in this county, so far as have been observed, of any practi 

 cal value. Analyses of this clay show it to have only traces of alkalies. It 

 may probably be of a fairly refractory character and suitable for a low grade 

 of fire clay goods.
