“The want of reliable geographic maps, and the fact that no contour 
maps of this section exist, together with a paucity of local names for many 
of the ‘mountains,’ as they are locally called, and the difficulty of finding 
persons acquainted with the boundaries of the headright surveys, has ren- 
dered exact outlining of the ore beds within the allotted time an impossi- 
bility, but sufficient data have been obtained to show the location and 
approximate extent of the beds of iron ore most suitable for manufacturing 
purposes, while other observed facts will tend to assist in determining the 
character and relations of the strata to each ’other, and the period of the 
formations as a whole.” !P. eii.

“The district composed of Panola, Shelby, Nacogdoches, and Rusk coun- 
ties, lying between north latitude Sl'^ and 32° 30' and west longitude 93° 
40' and 95° (examined during the summer of 1890) is mainly between the 
Sabinie river on the northeast and the Angelina River on the southwest. 
The whole three thousand, four hundred and ninety square miles is included 
in what is known as the ‘Timber Belt’ of East Texas. 
“The most characteristic feature of the topography of this district is the 
enormous erosion, which has ploughed out extensive valleys, and left the 
high hills (buttes) and ridges, locally called ‘mountains,’ as imposing wit- 
nesses of that potent agency. These hills and ridges, covered with forest 
trees, when viewed from an elevation, do, indeed, present the appearance 
of mountain ranges. 
“For a general description of the geography and topography of East 
Texas, with notes on the literature of the Tertiary formation, the reader 
is referred to the preliminary report by Dr. R. A. F. Penrose, Jr., in the 
First Annual Report of the Geological .Survey of Texas, 1889, and to the 
introductory chapter of this Report on the Iron Ore Districts of East 
Texas [E. T. Dumble].” 
“Panola county has an area of seven hundred and ninety-nine square 
miles, lying between north latitude 32° and 32° 30' and west longitude 94° 
and 94° 40'. Jt was created by division from Shelby and Harrison coun- 
ties in 1846.” P. 225. 
“The county is drained by the Sabine river, which runs through the 
middle portion, from the northwest corner to the southwest corner.” P.
