examples of what may be termed rudimentary coal-beds. Each 

 layer is plainly composed of prostrate trunks oiSigillaria resting 

 on Stigmarian under clay, and mixed with Cordaites, Alet/mj>- 

 teris lonchitica, and vascular bundles of ferns. In one layer is a 

 stump in the state of mineral charcoal. In another there are 

 coprolites, scales of fishes, Spirorbis, and fragments of Crusta- 

 ceans. In a reddish shale above these beds there is a patch of 

 gray sandstone interlaced with Stigmarian roots, as if the sand 

 bad been prevented from drifting away by a tree or stump.
