388 GEOLOGY OF NORTHWESTERN TEXAS. 



The coal seam in the above section is probably No. 7 of the general section, 

 but being exposed in only one place, and that at the top of a small anticlinal, 

 I was unable to determine. There are in places a small seam of coal above 

 Seam No. 7, and it may be that this is that thin seam.

In No. 1 of the above section I found a coral, abundant and very large, that I 

 I have seen at only one other place — on Mukewater Creek, near the town of 

 Trickham. This is at about the same geological horizon, and I take it to be the 

 same beds. The coral very much resembles Campophyllumf Some of the 

 specimens are two inches in diameter and eight inches long.
