GEOLOGY OF THE THIRD DISTRICT. 



The first, wood-cut No. 54, is from the group between Mount Upton and North-Bainbridge. 

 It resembles a coromon coal plant, but differs in having no markings whatever on the raised 

 surface between the fluted parts. It is a sigillaria, and if unknown, may be called Plain 

 ttgiUttria (S. simphcitas). The specimen is in the State Collection.
