MEETINGS. 87 



5. — St. Martin's. 



Some members of the Society having expressed doubts 

 as to the stratification of the deposits at Divette in the 

 manner reported in previous Transactions, this locality was 

 revisited and other sections along the coast between Fermain 

 Bay and Jerbourg inspected, the members of the Society 

 present on the occasion being satisfied that the conclusions 

 previously arrived at were justified. 



The widening of Rue Cauchee exposed 10 feet of sandy 

 clay showing signs of stratification at the corner of the road. 

 From Mr. Cameron's statements it appeared that no clay was 

 found in digging the foundations of his house on the same 

 field, the soil resting on decomposed rock. 



ROCKS. 



1. — Coast East of Vale Castle. 



The patch of rocks north of the reclaimed land on which 

 Griffiths & Co. have erected a stone-breaking machine, con- 

 sists of syenite with diorite. The diorite occurs in two forms, 

 viz. (a), inclusions, and (b), more or less distinct veins. Both 

 the syenite and diorite are cut by granitic veins of lighter 

 colour which in some places form a net-work in which the 

 syenite and diorite occur is angular fragments. The rock 

 thus resembles a dreceia, which by weathering acquires a very 

 peculiar appearance. It would seem that the granite was in 

 a comparatively cool condition at the time of its intrusion. 



2. — Coast between Albecq and Cobo. 



Two diabase veins have been noted cutting the granite. 

 One two feet thick where undivided breaks up into several 

 minor branches with a general east and west direction, is of a 

 green colour mottled with purple. Fragments and pebbles of 

 it might be mistaken for a fine grained sandstone. Another 

 dyke, 3 feet wide, similar in character and direction, was found 

 cutting quartz veins in the granite. 



3.— Petit Bot Bay. 



A very interesting vein of fibrous quartz was noticed on 

 the east side of the bay. The laminated diorite veins in this 

 locality are worthy of attention, and are similar to those in 

 Talbots Valley. 



4. — Moulin Huet Bay. 



The quartz veins here cut all other rocks ; in other words, 

 they are the most recent.
