the exception of fragments of crinoids, these have been the only- 

 fossils recorded from the Longwood shales. 



The iron taken from this mine is from the New Scotland beds 

 and along the contact of the latter with the Longwood shale. 

 The leached character of the red shales which are adjacent at 

 once suggests the origin of the iron. A brief description of this 

 mine together with the following analysis of the ore is given by 

 Putnam. 1

A study of the geological relations at the mine shows that the 

 presence of iron ore in the Xew Scotland beds is of local occur- 

 rence and is found only where the Xew Scotland beds are in 

 contact with the Longwood shales. Several openings in the 

 New Scotland beds north from the mine, have been made, but 

 without finding any ore. An examination of these nonproductive 

 openings shows that between them and the Longwood shale 

 there are at least 80 feet of limestones, which indicates that this 

 part of the syncline has not been affected by the faulting and that 

 further exploitation for iron, of the New Scotland beds north 

 from the productive mine will bring only negative results.
