Introduction
The region embraced in the following report lies between 31⁰ 10' and 32⁰ north latitude and 98⁰30' and 100⁰ west longitude. This area, about 4,000 square miles, includes nearly all of Brown and Coleman counties, Runnels county east of Norwood, the northeast part of Concho county or that part lying east of Paint Rock and north of Eden, McCulloch and San Saba counties north of Brady creek and the town of San Saba, the northwest corner of Lampasas county, Mills county west of the Gulf, Colorado and Santa Fe Railway, and a small area in Comanche county north and northwest of Comanche.

Preliminary examinations of the Carboniferous beds of this area have been made by Messrs. W. F. Cummins and R. S. Tarr, and like investigations of the Cretaceous areas have been made by Messrs. R.T. Hill and J. A. Taff.

These geologists have determined the stratigraphic relations of the divisions and terranes of these formations, and their classifications have for the most part been followed in this report. The work of the present season has been of a more detailed character than that hitherto undertaken. Each bed has been studied with reference to its extent, stratigraphic relations, lithologic characteristics, fossil forms, and economic features.
