character is practically impossible, we may say that the Creechbarrow 

 Beds, as determined from indications near the summit, have a dip 

 to the northwards of from 10" to 12°.

A. Solid concretiouary limestone in situ. 



B. Artificial nibble, mainly derived from the limestone.' 



The vertical section as shown in Fig. 2 is about 7 feet. 



The summit has been artificially flattened, and certain courses of 

 Purbeck stone (dressed) remain as evidences of the foundations of 

 the Keeper's Lodge which formerly occupied this site. About 

 a foot or eighteen inches below this we came upon a section 

 which is partly natural and partly artificial. The natural portion 

 consists of solid tufaceous limestone, showing certain irregular 

 divisions, but nothing that could be referred to bedding : the 

 jointing is in all directions with possibly a tendency to the vertical. 

 Alongside of this mass of natural limestone is a miscellaneous 

 rubble of artificial origin. The upper portion consists of small 

 calcareous rubble mixed with sand, flints, etc., down to a line of 

 blackearth. Below this is a conglomeration of looser stones, where 

 flints and large blocks of tufaceous limestone may be noted. The 

 whole probably rests on tufaceous limestone in situ lower down.
