thickness (C), and dipping down seawards at an angle of about 20°, 
roughly parallel to the eroded surface of the solid rock on which the 
whole series of drift deposits rests. This sandy bed cannot be 
regarded as equivalent to the ‘Blown-sand’. of the Cork district 
described by Messrs. Wright & Muff, for the latter occurs beneath the 
Lower Head, while at Newtown Head it rests upon the Lower Head (B). 
It must be regarded as marking a local episode on a sandy shore 
before the deposition of the Boulder-clay (D). The true Lower Head of 
Newtown Head occurs immediately beneath this layer of sand, and is 
composed of large angular fragments of the solid ‘ greenstone’ on which 
it reposes, imbedded in a very scanty sandy matrix. The blocks are 
quite irregular in size and arrangement, and are all angular and 
usually large, measuring up to one foot or more in length, but in one 
spot the fragments are of a smaller and more uniform size and show 
rough bedding. This mass of Head (B) rests on an uneven hummocky 
but rounded surface of ‘greenstone’ (A), and measures about 6 feet thick 
at its maximum, being banked up against the old pre-glacial sloping 
cliff and spread over the irregular rock-platform. In this instructive 
section at this point the Lower Head is seen to thin out rapidly to the 
east, so that the Boulder-clay overlaps it and comes to rest directly on 
the solid greenstone.

- On the north side of the headland the present cliff face is chiefly of 
solid rock and is much obscured by vegetation. Coarse angular 
rubble-drift may be seen in places near the top of the cliffs resting 
on the Ordovician rocks, and the subsoil frequently contains a layer of 
cockle-shells. The Boulder-clay reappears in about 300 yards at the 
top of the cliff, and rapidly increases in thickness northwards by 
descending to the present beach-level or nearly so, being as much as 
20 feet thick and forming practically the entire face of the cliff all 
the way to Raheen Stream. A layer of sandy clay or marl containing
