could get feed for the stock after leaving our camp in the vicinity of Dockum. 

 From Benjamin we traveled over the broad plateau between the Brazos and 

 the Big Wichita rivers to Seymour, the county seat of Baylor County. A 

 few miles west of Benjamin we left the gypsum formation, having been in it 

 since reaching Kiowa Peak on our outward trip, except the time we were 

 camped at Dockum. 



We began a line of levels at Flat Top Mountain, six miles north of Sey- 

 mour, in Baylor County, and ran eastward to Wichita Falls, for the purpose 

 of getting the thickness of the Wichita Beds of the Permian. The profile is 

 shown in another part of this Report. We found the top of the Wichita 

 Beds to be near the eastern line of Baylor County, at the place where our line 

 of levels crossed the county line. 



From Wichita Falls we returned to Baylor County and traced the line of 

 contact between the Wichita and Clear Fork Beds of the Permian to where 

 the line of contact reaches the Brazos River, and which is probably the most 

 southern extension of the Wichita Beds. The point at which we reached the 

 river is a few miles west of the mouth of Spring Creek, and of the northeast 

 corner of Throckmorton County. 



From thence we went down the river to the line of contact between the 

 Permian and Coal Measures, and then turned northeastward, tracing the line 

 of contact between these two formations to Red River, near the northwestern 

 corner of Montague County. 



We went to Henrietta, in Clay County, where I was joined by Dr. T. B. 

 Comstock, of the Survey, who came for the purpose of making a hurried 

 reconnaissance of the country in the vicinity of the Wichita Mountains in 

 the Indian Territory. We took the direct road to Fort Sill, crossing Red 

 River at the mouth of the Big Wichita River. Our route lay up the east side 

 of Cache Creek to Fort Sill, where we reached the contact between the Per- 

 mian and the Silurian and granitic rocks. We went from there along the 

 southern base of the mountains almost directly westward for fifteen miles, 

 then turning northward through a gap in the mountains we passed through 

 the range and found the Silurian resting upon the granitic rocks on the north- 

 ern side of the range. We turned southwestward and crossed the North Fork 

 of Red River into Greer County, near the town of Navajoe. From this place 

 Dr. Comstock took the stage for Vernon, while I turned eastward along the 

 Fort Sill road, recrossing the North Fork of Red River and Otter Creek; then 

 turning southeastward to the head of Deep Red Creek I continued down that 

 stream to its confluence with the Cache Creek, and thence down that stream 

 to the upper Henrietta road, and thence south, crossing Red River and Big 

 Wichita River to Henrietta, having been gone about two weeks. 



From Henrietta we went southward to the west fork of the Trinity River,
