146 MEETINGS. 



bones were not so abundant as last year, notwithstanding the 

 beach was tried in various spots hitherto untouched. The 

 flints and carbonized wood confirm the supposition that man 

 was present here at the time when the peat formed part of the 

 land surface ; but this year's investigations do not support 

 the idea that the peat in this locality belongs to more than 

 one bed. It would rather appear that all the exposures be- 

 long to the same layer, gradually but irregularly sloping sea- 

 ward. The irregularity of the slope is attributed to the 

 percolation of land water under the peat. This water, in 

 endeavouring to find its level, and being unable to penetrate 

 the peat, forces it up in various places. In some of the 

 excavations so soon as the layer of peat had been pierced by 

 digging, this underlying water welled up so abundantly as to 

 prevent further work. 



A bed of peat 1^- foot in thickness has been exposed in 

 digging a well about 100 yards inland from Grandes Rocques. 

 Vegetable remains were abundant, but no bones have been 

 discovered. 



B.— BEICK EAETH, HEAD, AND OLD BEACHES. 

 1. — Vrangue Brickfield, 



This brickfield requires visiting from time to time as new 

 sections are being continually exposed in the course of the 

 work. This year a pebble of red granite was found in the 

 upper pit at least 8 feet below the surface, in a band of rubble 

 about 6 inches thick lying between two sandy bands. In 

 another part of the same pit a small flint pebble was found in 

 sand. It was only as large as a small pea, and had one side 

 fractured, but it is sufficient to show that this sand is not 

 entirely derived from the disintegration of local rocks ; and 

 these finds seem to point to the former existence of an old 

 beach at a higher level, which has been so entirely swept away 

 as to leave only a few pebbles as tokens. 



In the lower pit various flint chips were found at different 

 depths in what seemed to be undisturbed head, consisting of 

 clay with angular rubble. A worked flint was picked up at 

 the foot of the cutting, which unfortunately could not be 

 located as to its origin. The working of this pit has this year 

 exposed the rock in situ, showing it to be a spur of the 

 diorite outcrop known as Mont Arrive, on which are the 

 remains of an old battery. 



2. — Barker's Quarry, 



A great landslip occurred last winter in this quarry (now 

 abandoned and in process of being filled up with refuse).
