'ba3'-ou a mile north of Batesville, oross'^s Miller creek four 
miles northeast of Batesville, and disappears about a naile north 
of Sharp's Cross Roads, in Independence county. It is thus 
traceable about seventy miles in a nearly straight line. 
The upper course of the P^ast fork of Cadron creek lies for 
twenty-five miles in a course parallel to these monoclines. The 
upper part of this stream, from east of Quitman to where it 
bends southward south-east of Springfield, flows along the 
bottom of a low synclinal trough. The- small parallel stream 
in 8 N., 13 and 14 W., flows bc^hind the ridge made by beds 
that dip beneath this syncline. The lower part of Salado 
creek to the northeast has about fifteen miles of its course in 
the same line approximately. 
In connecrtion with the northwest-southeast courses of the 
drainage of this region I would call attention to the fact that 
these streams are approximately parallel to certain escarp- 
ments of the north face of the Boston mountains, notably that 
between Wolf bayou and Mountain View. Adjoining this re- 
gion north of the Boston mountains there are also some gen- 
tle folds and faults. 
The bearings of a few of these intersecting structural lines 
are here brought together.
