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 Seymour, 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 Permian 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,
