been obtained, and it was deemed advisable that the 
collection should be placed in the Library of the Museum 
of Practical Geology, Jermyn Street, where it has since 
remained, and is available for reference to all those who 
take a real interest in or desire to make a proper use of it.” 
Reference to the Geological Survey Map will show that 
this little anticline is near a line of fault: a dislocation 
which is thereon represented to commence near Lancaut— 
the smallest parish in Gloucestershire—and to run thence 
southwards, for a distance of a mile-and-a-half, to the cliffs 
on the Wye a little to the east of the bridge at Chepstow. 
Possibly this faulting may have had some influence in 
rendering the anticlinal disposition of the strata more 
pronounced. There is little doubt that the time when the 
forces which came into renewed activity and caused pres- 
sure from approximately the east and west, so as to 
initiate this anticlinal flexure in the Carboniferous rocks, 
was at or near the close of the Carboniferous Period. 
It is well known that over the greater part of England, 
and even in Europe and America, great earth-movements 
affected the Paleozoic rocks, bending the strata into folds, 
and causing anticlinal and synclinal flexures to alternate ; 
“the folds,” to quote Dr Callaway, “being sometimes 
shortened so as to resemble elongated domes or ellipsoidal 
basins.” The genesis of this little anticline probably dates 
from this time.
