34 NOTES ON SUMMER EXCURSIONS. 



In the case of my own garden, reported last year, a cube of 

 4 feet yielded 58 pebbles. But the yield of flint chippings 

 and implements has also been numerous. 



I reported last year 54 worked flints from the 4 feet cube 

 of clay and this year I have to report that Mr. H. J. Morgan, 

 whose ground is at the back of my garden, has collected, after 

 a three-foot trenching, some hundreds of flints, all showing- 

 flaking by man and some few being implements of great value, 

 to which I shall allude later on. 



Before speaking of the flint implements I wish to 

 describe the detail of the year on the beaches, for they also 

 are involved in the flint finds. 



BEACHES. 



The pebbles in the clay, now found in such numbers, 

 seems to me to point to the existence, in former geological 

 times, of an extensive beach on the high land of the island, 

 300 feet. This, as far as we can judge at present, has been 

 entirely distributed. 



Some new exposures of the 25 ft. beach have been met 

 with. At the " Mare de Carteret " excavations have been made 

 in the road and on the growing estates which have enabled me 

 to draw an outline of the sea margin of that period.* 



I have also two new exposures of the 50 feet beach — one 

 at the Catellaine where a new cart-way into the quarry has 

 exposed a section of the beach with sand and head overlying 

 and red gravel with beach stones below, and one at the 

 Guilliotine quarry where the removal of the " head " has 

 exposed deposits of sand, pebbles and clay. 



I have also to report that in the Braye du Valle, at 

 Hawksbury, a deposit of pebbles being part of a beach was 

 passed through in digging a well. The deposit was 4 feet 

 thick, rested on rock and had 3 feet of clay over it. The 

 bottom of the deposit is at or about mean sea level, hence 

 may belong to the present period, and date from the time 

 when the sea was able to pass right through the Braye. The 

 members also had an opportunity of seeing the submerged 

 beach at Vazon. 



FLINTS AND IMPLEMENTS. 



Although not found during the excursions still I give a 



place to the finds of the year in this report, because one of 



the chief demonstrations was, as already stated, to give the 



geological horizon for these finds. 



* I have to acknowledge my indebtedness to Mr. A. J. F. Gibbons who notified 

 me of the excavations.
