Dip, east-30°-soiithat 70°? Coal soft. Elevation 430 feet. About 

 one hundred yards lower down^ within a few yards of the same bank, are 

 two or three old pits from which coal is said to have been formerly raised : 

 if so, it was probably from the continuation of the above seam. 



In the bed of the stream, about 10 yards west of the last outcrop, 

 one of a lower seam is exposed —

Dip, east-40''-south at 85°. The coal is somewhat contorted on a 

 small scale in places, but where not so, it is hard and firm. The elevation 

 here is about 300 feet. This seam is favorably situated for adit- working, 

 as it is nearly vertical and heads straight into the hill-side.
