116 PKOCEEDINGS OF THE GEOLOGICAL SOCIETY. [DoC. 20, 



are Sigillaria Broivnii, S. ScJilotheimiana, and other species, ft. in. 

 Stigmaria, Lepidodendron, Calamites, Cordaites, Sporangites 

 glabra, Aletliopteris lonchitica, Sphenopteris latifolia, Pinnu- 

 laria, and Cyperites ; also Cythere, Naiadites, and fragments 

 of reptilian (?) bones. The coal is pyritous, and exhibits im- 

 pressions of the bark of Sigillaria ; it contains also bast 

 tissue, scalariform tissue of JSigillaria, and multiporous tissue 

 of JSigillaria and Oalamodendron. 



(Sandstone and shale, erect Calamites and Sigillaria 

 with Stigmaria. The erect trees contain repti- 

 lian remains of the genera Dendrerpeton, liylo- 

 nomus, and Hi/Ierpeton ; also Fupa vetusta, Xy- 

 Zo^ms >Sz]^e7^anc?, and remains of insects) 10 



{Coaly shale. 

 Coal 6 inches G 

 Arenaceous underclay, Stigmaria. 



The erect trees above mentioned are rooted in the roof of 

 this coal. It contains Cyperites, Lepidophylla, Trigonocarpa 

 of 2 species, Sphenop>hyllum,Alethopteris lonchitica, Cordaites, 

 and Aster ophyllites. There are shells of Spirorhis on some 

 of the plants. The coal contains layers of bark of Sigillaria 

 and leaves of Cordaites, and much bast tissue, with scalari- 

 form, uniporous, and reticulated tissues, probably of Sigil- 

 laria. 



(Sandstones and shales; erect Calamites and Stig- 

 maria) 21 



{Grrey shale. 

 Coal 4 inches 4 

 Argillaceous underclay, Stigmaria. 



The roof contains Calamites, Sigillaria, Aletliopteris lon- 

 chitica, Pinnularia, Lepidodendron, Cyperites, Sporangites, 

 and Spirorhis. One Sigillaria extends 30 feet without 

 branching. The roof supports an erect tree. The coal is 

 filled with flattened stems of Sigillaina lying in different 

 directions, also flattened Lepidodendra ; and in its mineral 

 charcoal it has beautiful porous and scalariform tissues.
