Coal in Texas. 
■Geolo'giea!! and Scientific Bulletin', Vol. I, ^sTo. 2. Houston, 
1898. 
This article is, in the main, an attempt to combat “the prevailing incre- 
dulity as to the value of Texas coal deposits.” 
“Texas has about 25,000 square miles of Carboniferous formation, and 
that the coal measures of this formation hold good coal is received with 
the same incredulity as was formerly the assertion of the existence of 
ores.

“Last year I was professionally occupied all summer in tracing the Car- 
boniferous strata in the Chickasaw nation, along the Santa Fe railroad, 
and I found that the coal formation of the Indian Territory is evidently 
connected, at least in two places, with that of Texas, but the connecting 
streaks are mostly covered by thick strata Of more recent periods. 
“I also found that the Carboniferous strata of Texas show less upheavals 
coves, and other disturbances than those of the western part of Indian 
Territory, and that the conditions for the eventual working of the coal in 
Texas present fewer difReulties on account of water and gas.”

Brown Coal or Lignites. 
Geological and Scientific Bulletin, Vol. I, No. 3. Houston, 
July, 1888. 
A description \of the properties of brown coal or lignite; how it varies 
from true coal. iMethods of utilization -as fuel. 
“Many of the brown coal deposits of Texas are located conveniently near 
to railroads, in parts of the State where fire clay, potter’s clay and kaolin 
abound. They are found in the cotton raising counties, and can furnish 
a cheap and convenient fuel for cotton gins, cotton mills, ceramic factories, 
etc. 
“These deposits, which in places are twenty feet thick, and even more, 
are in most cases only a few feet below the surface, and consequently the 
mining is not exipensive, no costly shafts, hoisting, pumping and ventilat- 
ing machinery being required.” 
Prejudices against the use of lignite.
