GEOLOGY OF THE THIRD DISTRICT. 
The first, wood-cut No. 54, is from the group between Mount Upton and North-Bainbridge. 
It resembles a common 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 
sigillaria (S. simplicitas). The specimen is in the State Collection.
