120 - APPENDIX II. 



SOUTH OF MAIN ISLAND OF FUNAFUTI (Plate 9). 



A. Well-rolled pebbles along here. 



B. Large shifted flat blocks of breccia lying up the Hurricane Bank slope above the breccia cap. 



C. The breccia is much worn in places, disclosing several patches of hard foraminiferal sandstone, in 

 which Tinajmiis bacuhifus is the chief foraminifer ; this often occurs where there is either no breccia 

 above it, or, as is more usual, a thin sheet onh'. 



D. Big boss of breccia projecting beyond the present general line of the breccia cap and 6 feet al)ove 

 high water. 



E. Big flat blocks of breccia lying on the Hurricane Bank. 



F. Pebbles mingled with the blocks on the Hurricane Bank, most of which are worn. 



Ct. The breccia here is much Avorn and smoothed by the attrition of the pebbles at L.9.A. 



H. There are numerous caverns and pits in this clinker field. The trees also thrive and grow high near 

 them. 



J. Big flat l)locks here on slope of Hurricane Bank. 



K. Large blocks of Porifes fixed to platform or piercing it. 



L. The trees are small and stunted on this sandbank. 



M. The Ijreccia cap is seen to extend through from side to side in one sheet here. 



N. The In-eccia at the end of this island is worn down and being eroded, and is of diminishing width 

 and thickness, till very little is left towards the middle of the space between the islands ; this space is not 

 for its whole width of one character, but retains near the ocean face, at corresponding distances, much 

 of the character of the usi;al ocean platform, while towards the lagoon it is moi'c jagged and rough, 

 presenting a somewhat corroded appearance. Thin layers of pumice seen in places along this Iluriicane 

 Bank fi'om 1 to 2 feet from top. 



CENTRAL PART, ABOUT THE VILLAGE OF FONGAFALE ( Plate 9). 



A. Beach of large and small well-worn pebbles. 



B. Poriiex block, 7 feet by 4-^- feet by 3 feet. A pinnacle in the eroding reef 4 feet G iuclics above coral 

 platform. 



C Small hui'ricanc Ijeach of small lumps of breccia mingled with sand. 



D. Numerous breccia blocks here, above the top of the breccia cap, up to 2 feet 4 inches in diameter; 

 the coral l)locks and the breccia sheet below them are both more or less undergoing solutio)). 



E. Coarse, ciinkery blocks of coral and coral breccia. 



F. Large blocks of the breccia sheet shifted on to this Hurricane Bank. 



G. Escarpment of the breccia sheet 1^ to 2 feet high. 

 • H. Outcrop of the breccia sheet. 



J. Sandbank fails southwards and a depression of the surface landwards succeeds it. 



K. Blackish sandy soil. 



L. Mingled sand and pieces of breccia. 



M. Edge of solution of breccia cap. 



N. Solution line ; hollows with small pits and caverns. 



O. Breccia cap covered over with lai'ge coral rubble, east of this. 



Q. South depression extending from here to the swamp, which may prol^ably indicate some jiast 

 communication of. the swamp with lagoon. 



R. Between this and the clinker field the central depression continues. 



S. There are slight indications here of an oldj communication between this central depression and the 

 lagoon, though it is now in ^Dart filled up with sand.
