“In the First Annual Report of the Geological Survey of Texas the only 
reference made to Houston county is a .short notice of Cook’s mountain ( a 
high hill about two and a half miles west of Crockett) , and an outcropping 
of isthell-bearing sand about nine miles northeast of Crockett, on the old 
San Antonio road. In the Second Annual Report a more extended refer- 
ence to the economic geology of this county is made in a preliminary 
report by Mr. E. T. Dumble, State 'Geologist, which is taken for the most 
part from the notes of Dr. Penrose and the report of Dr. R. H. Lough- 
ridge on Cotton Production of the Southern States, Tenth Census, Vol. 5. 
“The present report is a description of the different features of the 
geology of the county from the .stanidpoint of a much more .detailed exam- 
ination than has hitherto been made, during which it was ascertained that, 
in addition to the con.glomerate iron ores already described, there are in 
the county also laminated and oarbonate ores, and that the soils can be 
more properly presented under a difficult classification than that employed 
previously. 
“In order to give the details as completely as desired, it has been found 
necessary to repeat and enlarge some of the work previously done.” P. 5.
