The geographical limits of the Kelloways Rock are not 
easily defined. The rock, or rather the beds of sand of 
which it consists, being only three or four yards thick, forms 
a low continuous terrace from South Cave to South New- 
bald, ranging nearly in the line of the public road from the 
former place to the latter, the terrace usually extending to 
the west of it for a short distance. The soil of the Kello- 
ways Rock is less intermixed with foreign debris than that of 
any other in the district, and may in all cases be said to have 
been formed by, and to partake of, the sandy nature of the 
subjacent stratum. The soil is even, if possible, more sandy 
than that of the Inferior Oolite, which contains 97 per cent, 
and the colour is generally dark brown. The extent of 
country formed by this rock is very small, upon an average a 
quarter of a mile in width, and extending in length from 
South Cave to South Newbald. Its sandy beds abound in 
casts of shells, and at the bottom of them are masses of a 
hard calcareous stone, marked by numerous remains of 
Gryphoea dilatata. The peculiar shell belonging to it is the 
Ammonites calloviensis. 
The Inferior Oolite, from the south of Elloughton to the 
north of Sancton, forms rather an extensive tract of country. 
The bed No. 1 (irony balls in sand) composes the basis of the 
soil from near Welton to Everthorp, a distance of 5 or 6 miles, 
and no perceptible difference can be discovered throughout 
this portion of their range, between the agricultural character 
of this bed and that of the Kelloways Rock. Around Ever- 
thorp, the sandy beds being denuded, the second bed of the 
oolite, i.e. the oolite in oblique laminae, comes to the surface, 
and alters the texture of the soil. Farther north the sandy 
beds again prevail, and are well exhibited, together with the 
variation in the quality of the land, half way between New- 
bald and Sancton, at Mr. Stephenson's farm. The two lowest 
beds of the Inferior Oolite are quarried as a material for the
