quantity of water encountered here, further sinking was 

 impracticable, and the excavation was stopped at a total depth 

 of 29 feet below the surface of the gravels, without the base of 

 Boulder Clay being reached. 



At the section exposed a short distance to the northward, by 

 the side of the road running from Larne to the Harbour, and 

 near the large stone building used as a grain store, an exami- 

 nation of the beds showed that the Boulder Clay, which contains 

 the characteristic polished and grooved pebbles, rises up at one 

 spot to within 2 feet of the surface, the gravels resting directly 

 on it. It dips rapidly southward and eastward, and runs down 

 under the section previously examined. This bank of Boulder 

 Clay is of small extent, as at the old pottery, about 200 yards 

 further north, the gravels are again seen resting on the 

 Estuarine Clay. Behind the store just mentioned a good 

 section of the gravels is exposed, some 12 feet in height ; the 

 base is sandy and rests on Boulder Clay. At a depth of 9 feet 

 below the surface a sandy layer was observed full of the littoral 

 bivalve Tapes pullastra. The pairs of valves were in all cases 

 in juxtaposition, and the plane of the valves perpendicular, 

 showing that they lived on the spot where they are now found. 



IV. — DISTRIBUTION AND CHARACTER OF THE WORKED FLINTS. 



The uppermost zone of gravelly soil yielded flakes in the 

 greatest profusion, at least 10 to every cubic foot, and it was 

 observed that they were most abundant in a pebbly layer in the 

 lower part of this bed, at a depth of i'-o" to i'-6" below the 

 surface. The flakes are all of a rude type, with little appear- 

 ance of secondary chipping, the edges blunt, and the surface 

 much oxidized ; undoubted cores are rare, and no scrapers or 

 other implements were here discovered. In the succeeding 

 4 / -6' / of gravel much fewer flakes were found, and their number 

 was observed to rapidly diminish as the depth below the surface 

 increased, and they ceased altogether at a depth of between 

 4 and 5 feet. In character the flakes found in this upper gravel
