in Jack County, for the purpose of tracing Coal Seam No. 7, which outcrops 

 in that vicinity. We went along the line of outcrop as far eastward as Mr. 

 Cooper's place, on the southeast quarter of section No. 2, made for the South- 

 ern Pacific Railway Company, file No. 2879. "We then turned southwest- 

 ward along the line of strike and traced the coal seam by its outcrop, passing 

 near the town of Gertrude, Flat Top Mountain, and the mouth of Coal Creek 

 to Belknap. 



From there we returned to the point on the Brazos River, near the mouth 

 of Spring Creek and near the eastern line of Throckmorton County, where we 

 had found the contact between the Permian and Coal Measures, for the pur- 

 pose of running a line of levels and making a complete section across the 

 Coal Measures. We began the line near the mouth of Camp Creek and ran 

 southeastward, passing through the towns of Belknap and Graham in Young 

 County, Finis in Jack County, Mineral Wells in Palo Pinto County, Millsap 

 in Parker County, to a point on the south side of the Brazos River near the 

 west line of Hood County and near the town of Buckner. 



At Rock Creek, five miles east of Mineral Wells, we had crossed Coal Seam 

 No. 1, and traced it by its outcrop both northeastward and south westward 

 along the line of strike for several miles in each direction. From Buckner 

 we went westward to Gordon, passing the town of Santo, for the purpose of 

 tracing Coal Seam No. 1 from where we had left off following it southwest- 

 ward on the occasion just mentioned. We traced the coal from hill to hill, 

 passing the old Gordon mine, the towns of Gordon and Thurber, and to the 

 Bridgefarmer place eight miles south of Strawn, where the seam is overlaid 

 by the higher part of the formation and Cretaceous. 



We turned north, and recrossing the Texas and Pacific Railway line at the 

 Coal switch, and thence to the town of Palo Pinto, and then northwestward 

 to Eliasville, in Young County, where we again took up the work of tracing 

 Coal Seam No. 7 from Belknap, where we had left off that work on a pre- 

 vious occasion. We traveled from there southwestward, passing Carbondale, 

 Crystal Falls, and the mouth of Sandy Creek, and thence up that creek to 

 Cisco, where the seam passes entirely out of sight under the newer beds. 



We then traveled west along the line of the Texas and Pacific Railway to 

 Putnam, and thence south, passing over the high Cretaceous hills to Pecan 

 Bayou, where we again found the Carboniferous formation. 



In order to get a complete section across the Central Carboniferous field, 

 and to secure data by which to correlate this part of the formation with that 

 north of the Cretaceous belt just mentioned, we turned up Pecan Bayou and 

 found the line of contact between the Carboniferous and Permian to be at the 

 head of the bayou, near the western line of Callahan County. At this point 

 we began a line of levels and ran southeastward down the bayou to Brown-
