tive of the beds of the lower Oolite. The Lias is, however, 
well developed at North Cliff. 
The Kimmeridge Clay is immediately subjacent to the 
great mass of chalk, and is of little importance in an agri- 
cultural point of view, forming only a zone of wet land about 
200 yards in breadth at the foot of the escarpment of the 
chalk. It is an exceedingly tenacious clay, which throws 
out the water of the chalk in great quantities at Newbald, 
Brantingham, Elloughton Dale, &c. This stratum suddenly 
disappears from under the chalk at Newbald. The ostrea 
deltoidea is the characteristic shell of this stratum. 
The next subjacent beds are the Kelloways Rock and the 
Inferior Oolite. These beds were first discovered in this 
locality by the Rev. W. Har court and Professor Phillips, 
and, geologically considered, they would require a separate 
description ; but since the crops produced upon them are in 
all respects similar, as well as the quality of the land, these 
two formations will be described too^ether in the aj^ricultural 
portion of this Report ; and they are marked nearly the same 
in the map, the Kelloways Rock being a shade or two darker. 
The detailed section of these beds consists of — 
f 1. Brown sand and stone. 
Kelloways Rock < 2. White and yellow sand. 
1 3. Sandy shelly blocks of stone (large size.) 
f 4. Irony balls in sand. 
Inferior Oolite... < 5. Oolite in oblique laminae. 
(^6. Oolite with the blue cores.*
