“Anderson county comprises the country lyin^ "between the Trinity and 
Neches rivers, bounded by Henderson county on the north and Houston 
county on the south, an area of one thousand and eighty-eight square 
miles.” iP. 303. 
“The rock forma/tions of Anderson county comprise representations of 
at least three systems:' The Cretaceous, Tertiary and Quaternary. The 
details of the entire istratigraphy of each system have not yet been worked 
out, but the follo'vving broader charaeters have been determined:

“The deposits of iron ore in Anderson county, like those of the entire 
distriot, are found capping the highest hills, or in the ease of some of the 
conglomerate ores,* along the water courses, either at their present level or 
more often at that of some time prior to the erosion of its present ehan- 
nel. As has already been stated, these deposits are found cresting a rude 
semicircle of hills, having for its diameter the Heches river, and are in 
fact the western extension of the deposits of Cherokee county.” P. 308.

“Lying immediately south of Anderson county, and situated like it 
between the Trinity river on the west and the Neches on the east, is Hous- 
ton county. This county, which has a total area of eleven hundred and 
seventy-six square miles, is bounded on the south by Trinity county, and 
is the most southwestern county of the iron ore district, as far as we were 
able to ascertain during the past field season.” P. 318. 
“The only iron ore areas so far examined in this county are found in a 
series of oval shaped hills which extend in a northeast and southwest direc- 
tion across the county north of Crockett.” P. 319. 
“In this county, so far as our investigations have shown, we have rep- 
resentC'd only strata of the Tertiary and Quaternary age.
