MEETINGS. 127 



No. 4.— Port Soif. 



This, a similar dyke, runs in a north-east direction, or 

 more exactly 75° east of north. 



No. 5. — Albecq Cutting. 



A thin dyke or vein runs through the red granite on the 

 land side of this cutting. Its dimensions are, roughly, 



6 inches wide and 8 to 10 inches high. Its bearings have 

 not been noted. 



CLIFF-HEAD. 



Measurements and photographs of Nos. 21 and 22 of a cliff- 

 head section at Divette Bay (under the Doyle monument on 

 the east side), have also been taken. This section, which is a 

 natural one, was caused by the sea clearing away a rubble 

 bank, or continuation of the cliff-head, which bank, resting on 

 a rock bed, formed a promontory. The rock bed is strewn 

 with pieces of rock of the same sizes and characters as those 

 now existing in the lower portion of the cliff-head section. 

 These apparently sank into their present places on the 

 removal of the supporting rubble. There is more than a 

 passing interest in this cliff-head owing to the rubble being 

 over an ancient or raised beach (No. 14), and this head proves 

 the following order of occurrence : — 



1st. — A sea shore extending further inland by some yards 

 than the present cliff. 



2nd. — A deposit of beach stones on a rocky bed 5 to 



7 feet above high water mark of considerable extent (see 

 drawing and plan). 



3rd. — An extensive destruction of overhanging rock with 

 a large deposit of various sized stones (many quite large) of 

 angular shapes, and but little weathered. 



4th. — A filling up of all interstices with clay, decayed 

 rock and rubble. 



5th. — The erosion by the sea of the promontory thus 

 formed leaving the present remnant as now seen. 



The measurements (see plan) are as follows : — 



a. Rock floor 165 feet long and 40 feet wide, with 

 loose rocky masses and stones resting where deposited, 

 1 to 5 feet above high water mark. 



b. Rubble section 22 feet high consisting of 1 foot 

 of clay and mould at the top. 



4 feet of clay. 



5 feet of rubble.
