The lower lignite beds are of excellent quality, firm and compact, 
and in some places show spots of fossil resin. The structure of the com- 
ponent wood is also in many instances very plainly apparent. The upper 
lignite lying immediately below the surface, is soft and decomposed where 
exposed, being in many places penetrated by roots from above. It might, 
however, prove equally compact with the lower beds where undisturbed. 
Layer 18, is one of the few instances in which lignite was observed to lie 
upon an evident underclay with roots. The ironstones are specially good 
and*compact in this section. Owing to the wearing away of the softer 
strata a large quantity of this material strews the surface of the hillside. 
211. This section does not seem to correspond at all with the last, 
though situated only a few hundred yards from it; and if no fault or 
break in the strata intervenes—and there is no appearance of any such— 
the horizontal uncertainty of the deposit must be very great. Fragments 
of a vesicular material, resembling scoriaceous lava, are abundant in 
this locality. The substance is produced by the combustion of the lignite 
beds, a phenomenon which receives attention on a subsequent page. 
212. Nearly three miles southward from the last mentioned locality, 
in following up the valley, another very good section occurs on the 
east side of the stream, where in one of its many devious windings, 
it has undermined the bank. This section is specially interesting, as 
affording one of the best localities for the collection of shells of Mollusca 
characteristic of the formation. The section is as below, measurements 
being estimated :
