224 RAISED BEACHES, CLIFF AND RUBBLE HEADS. 



The whole of these raised beach deposits are either 

 completely conglomerated and cemented together or are im- 

 bedded in clayey material of the head. The whole series give 

 the impression of great age, and where protected from 

 weathering are capable of being detached in large pieces from 

 which the individual pebbles are with difficulty removed. 



On the raised beach, and where it is missing on the rocks 

 themselves, rests the cliff head, to be described later on. 



Small patches of similar beach and head deposits I have 

 found at the Bathing Places. Professor Ansted states that 

 there exists a deposit at the Terres. I have, however, found 

 none at the Terres proper, though the remaining mound at 

 the old Gentlemen's Bathing Place contains the rubble 

 associated with the top of the beach and may have shown 

 rolled stones some years ago. The patches I have found are 

 nearer to the Valletta 



A very small pocket existed last year at Castle Cornet. 

 I have not looked for it lately and expect that it may have 

 disappeared. Its presence, however, proves the Castle rock to 

 have possessed a beach of the 25 feet level. 



Passing on to the lower parts of the island, I must name 

 a patch of beach found last year at the Arcade. This Mr. 

 Carey proved to have an elevation of about 27 feet. This 

 deposit thinned out and was overlaid by yellow clay. 



We may fairly associate it with the same level as the 

 beaches along the rock platform. It rests on gravelly decom- 

 posed rock, but no doubt the rock was hard and that the 

 beach was rolled on its surface when in course of formation. 



Forty feet below the surface at the upper part of the 

 Truchot there exists 7 feet of rolled stones. The levels justify 

 the belief that this deposit is one of an extensive beach 

 formerly washing the base of the Cotils Hill. 



On the north side of Mont Arrive, in the low ground 

 between the Bouet and Ivy Castle, recent excavations show that 

 there exists, some six feet below the present soil, extensive 

 beach deposits. The levels of the neighbourhood (Hougue 

 a la Perre = 26*00 feet), justify the association of this with 

 the same period as the rock platform and 25 feet beaches. 



A well-defined patch has been exposed to view in the 

 " Tunnel " quarry behind the Second Tower. This deposit 

 seems to have been laid from the south side of the local rise 

 at the former base of the Delancey Mount.* 



At Spur Point a deposit has been carefully measured by 

 Mr. Cooper. This deposit is 10 feet above high water mark.*
