142 
sides of the Cutting to within half a mile of the Wakefield 
and Pontefract turnpike road, when they are broken off by a 
Fault that re-introduces the Sharleston Coal seams dipping 
fast to the Southward. Consequently, the ridge between 
Goose-hill and Oakenshaw through which this excavation 
passes, appears to be an anti-clinal axis. 
Crossing the stupendous viaduct over the Barnsley Canal, 
the railway enters the Chevet Sandstone near Walton, and 
continues in the same formation through the Chevet tunnel. 
The deep Cutting at Notton High Bridge presents some 
singular and interesting features. Several Faults occur which 
cause the dip of the strata to vary considerably. Their 
general rise, however, is towards the South. A bed of Coal 
three feet thick is here passed through, which is supposed to 
be the " Shafton coal." The teeth and scales of fishes have 
been found in the shaly roof of this Coal, and the Chevet 
sandstone lies almost immediately beneath it. The Whin 
Cover Cutting, the Cutting at Cudworth station, and the 
Cutting to the Southward thereof, are in the Chevet Sand- 
stone ; the beds of which for the most part dip to the south- 
east. Near the 50th milestone at Little Houghton, the 
" Billingley Coal" — which corresponds with the ''Shafton 
Coal," is found about four feet thick. At this point the 
measures dip southward ; but at Billingley colliery they rise 
in that direction. 
The railway then enters the Darfield tunnel which passes 
through a hill of Chevet Sandstone, The same rock is 
worked in Cat-hill quarry, near Darfield station, and affords 
excellent building stone. 
The report on the Geology of the remaining portion of 
this important line of railway is unavoidably postponed, in 
order that the committee may have an opportunity of examin- 
ing more minutelv the interesting excavations in the neigh- 
bourhood of Swinton, Rawmarsh, and Masborough,
