was abandoned, the party next opening the first seam above the 
Conglomerate. The Conglomerate seam is composed of alter- 
nating laminz of dull black charcoal and brilliant black por- 
tions. It is much fractured, and somewhat friable, showing 
sulphur abundantly in weathering. The junction of the roo 
with the coaly matter is extremely sharp and well defined. 
The roof is composed of flaggy sandstone, with many well-pre- 
served impressions of plants. The floor is composed, not of 
the usual fire-clay, but of a curious conglomerate, consisting of 
rounded fragments of fine grained grey sandstone, and a very 
fine gray shale, all cemented by shaly matter colored with 
coaly matter. The shaly fragments are something like the blue 
shale mentioned as occurring lower in the series. 
The plants found in the roof deposits merit careful explora- 
ea P had a very short time to devote to the collection of 
them.
