the spur commences as an undulation, and gradually deepens 

 until it passes downwards through the Freestone beds, where it 

 is contracted into a gorge. Near the top of the hill there are 

 indications of a fault running across the spur, the ground being 

 slightly depressed on each of its slopes. The Fuller's Earth is in 

 the depression which runs down into the gorge on the north- 

 west ; it occupies a small area but it is of considerable depth, a 

 well having been recently sunk in it to the depth of 35 feet. From 

 the well it may be traced down the slope of the Combe, and 

 across it to the other side. It contains broken pieces of thin 

 shelly bands, which characterise the formation, with valves of 

 Ostrea acuminata. Its preservation is due to the exceptional 

 character of the depression in which it lies. On the sides of 

 the depression the Trigonia beds are in situ. There must 

 therefore be a fissure in the Inferior OoHte of considerable 

 width and depth, into which the Fuller's Earth sunk down or 

 shpped from the higher ground— probably the latter, because 

 it continues into and across the bed of the Combe, as before 

 stated. In the Combe it would of course be subject to the 

 wasting action of the springs which continued to run down its 

 bed while any Fuller's Earth remained on the higher ground to 

 throw off the water, but before the Combe was cleared the 

 springs ceased to flow, and the deposit of Fuller's Earth remains, 

 except so far as it has been since wasted by surface drainage. 

 There is no other trace of Fuller's Earth between Doverow Hill 

 and Birdlip, and the nearest bed of Fuller's Earth is two miles 

 distant from Whiteshill. I have considered it desirable to 

 place upon record the fact of the presence of Fuller's Earth at 

 this place, as bearing upon the subject of denudation, and as 

 evidence in confirmation of the opinions I have before expressed 

 upon it.
