SECTION OF THE SOUTH JOGGINS. 173 



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

 layer is plainly composed of prostrate trunks oi Sigillaria resting 

 on Stigmarian underclay, and mixed with Cordaites, Alethop- 

 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 fi-agments 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 

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