14. Coal vein, Gart. No. 5 Mine, Clay county. 
Figure 11 of plate I and figures 5, 11 and 12 of plate II are from 
sketches by Mr. E. M. Kindle, assistant on coal survey. With the 
exception of figures 1-4, 6-8, 10, 14, of plate I, and figures 13 and 14 of 
plate 11, all the figures are in the scale of 1 inch—10 feet. 
As it was the writer’s purpose in this paper merely to call attention 
to one of many interesting geological features of the coal regions which 
appear to have escaped notice, no descriptions of individual faults are 
given here, as they will be included in the monograph on the coal of 
Indiana, in preparaton.

A GroLocicaL Section Across SourHERN INDIANA FROM HANOVER TO 
VINCENNES. By J. F. Newsom. 
[Abstract.] 
During the field season of 1896 a geological section was run through 
the center of the row of townships numbered 3 N, from Hanover on the 
Ohio River to Vincennes on the Wabash. 
The profile was run by means of the vertical arc and aneroid barom- 
eter. The dips of strata and elevations as shown may be depended upon 
within the limits of these methods. 
The geological formations and the topography crossed by this section 
are typical of almost the entire southern portion of Indiana. 
The lowest rocks to be found in the section are the soft beds of the 
Cincinnati group along the Ohio River. These beds are about 250 feet 
thick in the region near Hanover. 
Overlying the Cincinnati beds are the hard limestones of the Clinton, 
Niagara, and Corniferous. It is this combination of limestones overly- 
ing the soft Cincinnati beds that causes the bluffs along the Ohio River. 
and the waterfalls that are so common in that region.
