“The general surface of this country is hilly and undulating. The high- 
est plains, or remnants of the original Tertiary deposition, are in the 
northwest and southwest portions, where the buttes and ridges, having a 
trend from la little north lof east to' a little south of west, hiave been formed 
by erosion from the original Tertiariy plains. The estimated %eight of 
these is from six hundred to se\'en hundred feet above the present sea 
level.” P. 226. 
* * ***** 
“The top soil of the buttes and ridges is very sandy, probably from the 
leaching action of rain water. The soil on the sides of these elevations 
partakes of the nature of the top, mingled with the under stratum of red 
ferruginated and mottled red and gray clay. The soil on the low lands 
and alluvial bottoms is composed of a mixture * * of the finer 
particles of the other two.” P. 226.

“In the northwestern part of the county, on the summits of the highest 
ridges and hills, there are remnants of the original iron ore deposits.” P.

“This county, lying between north latitude 31° 35' and 32°, and west 
longitude 93° 50' and 94° 30', has an area of eight hundred and two square

“This county is watered and drained on the east by the Sabine river, 
which forms its eastern boundary, and also the boundary between the 
State of Texas and the State of Louisiana. 
******* 
“The western and southwestern portions of the county are watered and 
drained by the Attoyac Bayou, which forms the western boundary of the 
county.

“The high ridges, originally a part of the elevated Tertiary plains, 
extend, as remnants, from the northwest corner to the central southern 
boundary, forming the watershed between the tributaries of the Sabine 
■River on the east and the tributaries of the Attoyac Fork of Angelina 
River on the west.”
