544 GEOLOGY OF NORTHWESTERN TEXAS. 



ried and are of an excellent color. They are not so easily worked as the 

 sandstones, and have not been utilized to any very great extent. The lime- 

 stones make a good article of quicklime when properly burned. 



Bricks. — Good clay for brick making can be had at many localities. The 

 quality of brick made is good. For ordinary purposes they are as good as 

 any in the State. The clays are abundant in the county for making the very 

 best quality of bricks, but are not always mixed with the proper amount of 

 sand ; but this defect can be easily remedied, as there is sand in abundance 

 in easy reach of any given locality. Again, other clays are too sandy and 

 make brick that are not sufficiently compact to stand heavy pressure. But 

 mixing a portion of the clay found everywhere in the Carboniferous strata 

 will very readily remedy this defect. 



OIL. 



In a well at Brownwood oil has been found that rises on the top of the 

 water and is brought up in the buckets. The amount is small, probably 

 only a few gallons per day. 



Recently a company has been organized to prospect for oil in this vicinity 

 and determine the extent of the oil bearing field and the quantity to be ob- 

 tained. 



COAL. 



Very little coal has been found in this county, and there is not much pros- 

 pect that workable beds will be found. 



Coal Seam No. 7 crosses the northwest corner of the county. It crosses 

 Pecan Bayou in the vicinity of Bird's old store and runs southwestward from 

 there in the direction of Waldrip, in Coleman County. 



EASTLAND COUNTY. 



I have only examined that part of Eastland County which lies north of the 

 line of the Texas and Pacific Railway, and will not attempt a description of 

 any of its natural resources in the present Report except that of the coal in 

 the northern part of the county. The only place where any prospecting has 

 been done in this part of the county is near Cisco. 



The mines at Cisco are on seam No. 7. At one time and another there 

 has been considerable work done on this seam in the vicinity of Cisco. The 

 outcrops are numerous. The seam is twenty inches thick, with a band of 

 slate above it, followed by a seam of coal four inches thick. The band of 

 slate is from four to ten inches thick between the coal seams. At another 

 place where I examined this seam there are nine inches of coal and twenty 

 inches of bituminous shale.
