“The principal body of bituminous coal in Texas lies in the northern 
central portion of the iState, extending southwest from the Red river in 
!Montague county, bo the Colorado river. This basin is a continuation of 
the great Fourth or Western field, of wihich it forms the southern extremity. 
It is said to underlie the whole or portions of 25 counties, and embraces an 
area of 12,000 square miles.” 
Worked in 1889 by the Texas and Pacific Coial iCo. in Erath county. 
“The field next in importance * * * lies along the Rio Grande, 
underlying the Webb, Dimmit, Zavala, Uvalde, Medina and Maverick 
counties, known as the Nueces ooal field, and embraces about 3700 square 
miles.” The principal developments are at Santa Tomas and Eagle Pass. 
“An extended area, bounded by lines drawn from iClarksburg [Clarks- 
ville], in Red river county, southwesterly to the Rio Grande, and thence 
northeast to the Sabine River, in Sabine county, is said to contain import- 
ant deposits of lignite.” P. 407.
