[part II. 



At the south side of the island lying against the steeply sloping 

 beds of the anticlinal with an apparently very high dip approachino- to

 by laterite. But little of these rocks is seen^ and that little has the 

 usual tendency to weather so as to conceal its bedding. Supposing the 

 laterite, however, to represent the sub-nummulitic group, the steepness 

 of the angle at which it appears to dip to the south is remarkable.*

brown or black silt which cracks on drying, the surface having fre-

 the salt which it contains. 



There are some other flat ' beers^ or ' bets'" to the west which have 

 no remarkable features.
