being full of rock-fragments and looking as if composed, as it probably 

 is, of re-made 'head.' It is capped by 15 inches of hill-wash-dune 

 with land shells, and at the base Patella. Over all is a layer of slate 

 fragments 4 to 6 inches thick immediately succeeded by the turf. 



This is Mr. Warren's furthest north and his starting-point. 



Careful search, however, did not result in the finding of any more 

 pieces of pottery. 



On either side of the path to the top of the headland are further 

 remains of hill-wash-dunes with land shells, but they cease in a few 

 yards, and all over the headland the surface soil, which is about 

 9 inches thick, resting directly on the killas, contains no remains 

 of shells whatever, though snails live on the spot. The same is the 

 case on East Pentire headland. 



Following round the west side of the To wan Head the next section 

 is beside the path (0) leading to the ruin of the old quay. Here there 

 is a sandy seam resting on the killas and overlain in places, especially 

 at the point P, by slate rubble. At the top of this seam at one spot 

 were some burnt slates and a few shells of Purpura and Mytilus. 

 A deep fissure in the killas was filled as follows : — 



ft. in. 



1. Sand seam ... 9 



2. Sand with fragments of slate and rock : the equivalent, 



seemingly, of the ' Head ' 6 



3. Indurated sands, showing current bedding ... ... .. 15 



These rest on an old platform of killas rising 8 to 1 feet from 

 a second platform of the same that is raised 10 to 15 feet above the 

 heach below. 



Yet a little further north a sloping path (Q,) leads into an old quarry 

 in the cliff. Between P and Q, under about 2 feet of top soil, there 

 appears to be about 4 feet of ' head,' or its equivalent, and beneath 

 this some 20 feet of indurated sands, deposited over and between 

 projecting reefs of killas. 



Where the path begins to descend the upper portion of the section 

 is obscured by a talus of slate rubble, and similar rubble caps the 

 killas in the quarry (R). 



Under the path the indurated sands are extensively piped. Most of 

 these are filled with ordinary earth, but three or four contiguous pipes 

 contained a purer sand than seen elsewhere, full of land shells, the 

 wrecks of some deposit of which no trace now remains above. The 

 moUuscan fauna gathered here differed markedly from collections made 

 elsewhere in the neighbourhood, as will be seen from the list given in 

 the table (p. 85). The bulk is made up of a high- spired variety of 

 Selicella virgata, having a single peripheral band. Of these 1,186 

 specimens were counted, while there are only 16 having more than 

 one band and 127 without any. 



No dune deposits exist over the northern part of the Head, but on 

 the eastern side at a point (S) nearly exactly opposite to Q, there is 

 a small cirque sloping down to the sea. By the edge of the path that 

 runs round it about half-way up, the soil exposed is seen to consist for 

 the most part of slaty rubble, but almost in the centre of the cirque 

 there is an inlet, or pipe, of sandy material with land shells.
