No indications of coal No. 4 were noticed, and its place is about 

 midway between coals 3 and 5, but with that exception the whole 

 series from No. 2 to 15 come in in regular order, and are readily 

 identified. The product from No. 2 in this shaft is a clean bright 

 coal, apparently nearly free from iron pyrites, and, judging from 

 its external appearance, sufficiently free from all deleterious sub- 

 stances to be used in its raw state for smelting iron. A block of 

 the roof shale of No. 5 was sent to my office by Mr. Jonte, and I 

 found it filled with Discina nitida, Lingula mytiloidcs and Cardinia? 

 fragilis, which characterize this coal in all the shafts in this and 

 the adjoining counties, and fix the horizon of that coal in this shaft 

 beyond question.
