water, wliicli has washed away the softer parts, leaving the 
harder standing in elevated patches jutting up into the lime- 
stone overlying it. The limestone, of which about 15 
feet are exposed, is yellow, contains numerous sparry cavities, 
and in its lower beds presents the appearance of a con- 
glomerate, from the great number of pebbles of quartz it 
contains, derived from the grit rock below. 
Near the entrance lodge is another quarry, in which the 
grit rises quite to the surface. It is similar in composition 
to the one already described, the white sandstone is occasion- 
all}^ stained yellow by the presence of iron ; the upper part of 
the right of the quarry is thinner, and somewhat flaggy. It 
has exactly the appearance that many of the grits present 
further westwards, where a bed of sandstone, cropping 
out on a hillside, has been crushed and broken by some 
lateral pressure. The whole section is evidently Rough 
Rock. Outside the park gates are other quarries, similar to 
those described, exposing the sandstone, with limestone 
above it quite unconformable. 
South of Bramham Park, the strata beneath the lime- 
stone escarpments are principally composed of shales, a thin 
bed of sandstone being occasionally present. The thick- 
bedded quartzose sandstones, so prevalent further north, 
have disappeared. Remembering that the Fault at Kiddall 
Hall throws up the Coal-measures against the Rough Rock, 
the occurrence of a large proportion of shales is exactly what 
might be expected, and bears evidence to the correctness of 
the conclusion. Near Barwick-in-Elmete the river Cock and 
its tributary have cut a deep channel through the lime- 
stone, and in several places their beds are composed of 
shales and tliin sandstones of Carboniferous Age. At Potter- 
ton Bridge, half-a-mile north of Barwick, the shales are well 
exposed in the banks of the stream. They vary in colour 
from a deep purple to the grey colour of tlic ordinary Coal-
