The coal bed reported in the above table at the bottom of the hole is 

 said to have been a fraud. According to Dr. Arthur B. Emmons, 1 "no coal 

 core was ever cut in the hole, and the coal core exhibited as having been so 

 cut was cut at the top of the hole from a piece of coal brought onto the 

 ground for the purpose." 



In June, 1895, I visited the locality, and from an examination of some 

 of the cores then obtainable on the place was able to make out the dip of 

 the beds as varying from 10 to 15 degrees, figures which agree with the 

 southward dips of the strata on the same strike line in Perrins railway cut. 

 The red conglomerate which appears at a depth of 320 feet is suggestive of 

 the reappearance of members of the Wamsutta series ; but from a comparison 

 of the section of this portion of the Coal Measures it is difficult to conceive
