SUBTERRANEAN GEOLOGY OF SOUTH-EASTERN ENGLAND. 145

dary rocks, there is anything in
the disposition of the Palaeozoic
beds suggesting a continuation
there of this Franco-Belgian ridge.
In the Mendip Hills of Somerset-
shire we have, as Godwin Austen
observed, its undoubted pro-
longation westward. For they
consist of an anticlinal ridge of
Palaeozoic rocks (Old Red Sand-
stone and Carboniferous Lime-
stone), ranging a little south of
east and north of west, the strike
of the Jurassic rocks east of the
Mendips being nearly north and
south. The Mendip Hills, as
Mr. H. B. Woodward reminds
us,3 do not form one simple
anticlinal fold, but their structure
comprises a number of folds
trending in an east and west
direction (fig. 2). Across the
Bristol Channel they are seen to
be prolonged in the southern
promontories of Glamorgan and
Pembroke.
These Mendip Hills are the
representatives in England of the
Condroz Crest of the Coal-field
of Namur. As that coalfield
was on the northern side of
the Condroz Crest, so here in
England we see on the northern
side of the Mendip Hills and
their continuation in Pembroke
and Glamorgan the coalfields of
Bristol, the Forest of Dean and
of South Wales. Therefore we may fairly expect that east of
