reported. This is attributable partly to the fact that the earthquake occurred 

 before most people were about, and partly to the fact that buildings here are 

 built on high piles, with the primary idea of withstanding shocks. 



' It is noteworthy that since the earthquake occurred, about a fortnight ago, 

 scarcely a day has passed without several minor tremors.

The Secretary then read the following communication received 

 from Keginald Eaoll Lempriere, M.A., F.G.S., concerning a 

 raised heach at South Hill, St. Helier (Jersey), of which a de- 

 scription was originally published bv the late Dr. Andrew Dunlop, 

 in Q. J. G. S. vol. xlix (1893) pp. 523-25 :— 



' In the 36th Bulletin of the Societe Jersiaise (1911), Dr. Dunlop dealt with 

 the objection made in the discussion, which followed the reading of his paper 

 published in the Q. J. G. S., that no shells or other marine organisms had been 

 found in the raised beaches, and this view was subsequently supported by 

 Geinitz. " But this objection is of little value, for in many, if not in most, of 

 our present shingle-beaches no shells or marine organisms are to be met with, 

 as they are ground to pieces and destroyed by the comparatively large pebbles 

 of hard heavy rock. The only alternative, also, to a marine origin would be a 

 fluviatile one ; but it is not easy to see how a river could have laid down the 

 beds of gravel on the southern, northern, eastern, and western shores and 

 slopes of the island, and filled up caves on the north coast. Further, the large, 

 smooth, well-rounded pebbles of hard granite and diorite look more like the 

 work of the sea than of a river ; and, in fact, it may be safely concluded that 

 there was a marine submergence. As the raised beaches contain no organic 

 remains (at least none so far have been found), it is difficult to give them an 

 exact geological date ; indeed, we cannot be sure that they all belong to the 

 same part of the Quaternary period, though this seems likely. They are 

 probably of early Pleistocene age and contemporary with some of the raised 

 beaches of Britanny, of Northern France, and of Southern England." 



' In company with Dr. Dunlop I have formerly viewed from a distance the 

 line of sea-pebbles exposed on the face of the high cliff east of the South 

 Hill battery ; but no attempt to make a close examination was possible, and 

 it could not easily be cut into on the cliff-face. Its westward extent was 

 quite unknown. On October 30th, 1918, by the invitation of Major T. E. Naish, 

 R.E., who had notified me as soon as he had struck the beach in the course of 

 the military works undertaken, I visited the spot in company with Mr. Emile 

 Guiton, a member of the geological section of the Societe Jersiaise, and took 

 note of the great mass of seaworn granite-pebbles and boulders already 

 exposed. The beach from the face of the cliff going westward forms a tongue, 

 and the excavations had struck across a spot nearing the tip of this tongue. 

 With the exception of a few small stones of diorite and diabase, the sea- 

 worn rounded shingle was perfectly uniform in character, consisting of a 

 fine-grained granite, brownish pink in colour, and having a greater excess 

 of hornblende and less quartz than the granite of the northern coast 

 of Jersey. In fact, the rock may be described as closely approaching to 

 a syenite-granite. As usual, the smaller pebbles were on the top, and 

 increased in size until the floor of the gully was struck. I again visited 

 the excavations in company with members of the Societe Jersiaise on 

 December 31st, 1918, and on January 11th & 22nd, 1919. On the two 

 last-named dates we were permitted to take photographs of the sea- 

 beach and of the gully in which the deposit lay (or rather had lain), for 

 the gully, so far as opened out, hael been cleaned in order to give a full 

 inspection. The walls of the gully were polished exceedingly smooth, and 

 exhibited superficial fissures. Many similar gullies are to be seen equally 

 worn, at or below high-water mark, around the coast of the island. The total
