depth, especially on the side toward B; but they are generally 
axis plane, approximately bisecting the angle at B, it would of 
course incline to the eastward from B in its descent, as repre- 
sented in fig. 1. Accordingly the most frequent strikes, and 
generally the best wells, are not on the side next to the slope, 
ut on the eastern half of the strip, toward C, where this main 
line of crevices, in its eastern ramifications, would cross the above- 
mentioned sandstone, after it has become horizontal. 
On the eastern margin of the inner belt, the main if not the 
only developments are on Gales’ fork of Myers’ creek, about 
three and a half miles north of the railroad, where there are 
some good wells, confined to a similar narrow strip, just west of 
F; but the production is not so large, in proportion to the num- 
ber of wells sunk, as on the western margin. 
_ On the inner axis, at E, and a short distance to either side of 
it, there have been numerous strikes on Oil Spring run, from 
One to two miles north of the railroad, and on Hughes river 
have been made in the areas that lie between the three produc- 
Ww ner 
es, are too far off to approach the region of the axis-plane 
her.
