122 MEETINGS. 



afforded an opportunity of viewing an important deposit of 

 blue clay. The clay is fairly free from sand, and is at least 

 14 feet thick, but layers of sand are found interspersed. It 

 appears to be on the same level as clay deposits which exist 

 right across the higher levels of the Braye du Valle, and 

 on the west side of the Capelles, but this connection, though 

 probable, has not yet been proved. 



4. — Grande Mare. 



Clay, blue in colour, and somewhat tenacious, has been 

 exposed during excavations for greenhouses in the above- 

 named district. This was viewed during an excursion, but 

 it was noted simply owing to want of time. 



SAND. 



1, — On reference to the drawing and plan of the Vrangue 

 Brickfield, it will be seen that the sand layer exposed to view 

 is a mere remnant of the original deposit. 



At its north end it is 2 feet 3 inches thick, at the south 

 1 foot 10 inches, where the workings turn westward, and 

 along this face the sand rapidly thins out, disappearing at 

 a distance of about 12 feet from the angle. Along the north 

 and south face it is thinnest at C, bemg there about 1 foot 

 4 inches deep. One or two rounded flint pebbles were found 

 at the base of this deposit. 



2. — Sand Dunes. 



Sand dunes have been recorded in the following places 

 as existing over sea- washed rocks of ancient date : — 



a. At L'Islet, where the blown sand is found covering 

 sea- worn rocks 15 feet above high water mark, and 300 feet 

 from the present high water mark. (See plan and 

 photograph 1.*) 



b. At L'Islet, near Rousse, the same conditions exist. 

 (see photograph 2.*) 



c. Along the Rousse and Ronceval coasts, but well 

 inland, where they not only cover sea worn rock, but old 

 walls. 



The detailed examination of these spots has proved 

 more than could be undertaken, but enough has been noticed 

 during the excursions to prove that a large amount of 

 interesting and valuable work is ready to be undertaken next 

 season.
