ticular 5 



12. Greenish-gray argillaceous shale. Thickens to the 



westward 2 



13. Gray and rusty sandstone and conglomerate, irregu- 



larly mixed. This is on the strike for some dis- 

 tance, then the overlying 'No. 12 comes to the 

 water-level. The top of No. 10 is at the water- 

 level at the first little brook in Birch Cove. Here 

 bands that represent ISTos. 8 and 9 are, however, 

 Indian-red, the material being still sandstone and 

 conglomerate. Then rocks of a bright red color

The top of 110 feet of reddish and gray sandstone and con- 

 glomerate, for the most part red, with coal-pipes, and veins of 

 barytes in the joints, overlying No. 13, comes to the water-level 

 at the second little brook in Birch Cove. 



From this point 60 yards west, a large brook empties and a 

 little brook comes into it. The brook turns from S. 15° W, the 

 shore runs I^. 53° W. to a headland, then trends more westerly. 

 The top of the following descending section here comes to the 

 water-level, probably about 13 feet below the top of the 110 feet 

 above mentioned or 97 feet over ISTo. 13.
