This strip has been traced for nearly a mile to Foster's Hall Wood, 

 beyond which it seems to run in under the coral-rock. 



The white earths are brought in again by a fault which strikes 

 south-westward from near Bathsheba Station. Prom this fault they 

 run westward, forming a slope which is nearly half a mile in breadth, 

 with a dip to the south-east. At the same time the base of the 

 Oceanic Series rises rapidly to the west, from a low level near 

 Bathsheba to a height of about 900 feet between Horse Hill and 

 Little Island, where it runs under the coral escarpment. Another 

 fault, however, brings it down again below Little Island and Castle 

 Grant. 



By Chimborazo and Maynard's a large tract of these deposits is 

 brought in between two great faults, and another long tract runs 

 from Bloom sbury by Mallard's to Spring Vale, being separated from 

 the Maynard area by a long narrow strip of Scotland Clays, which 

 can be clearly traced when the sugar-canes are off the fields. In 

 both these tracts the prevalent dip is to the south-east. 



West of the Caledonia fault there is only a narrow tract of 

 Oceanic Deposits below the coral-rock, and for about half a mile 

 they still dip to the S.E. ; on Highland estate a change occurs, and 

 thence by Canefield and Mount Misery the beds dip to the north-east, 

 the outcrop at the same time spreading out till it is three-quarters 

 of a mile wide. 



A fault running E.N.E. from Farmer's Gully then throws the beds 

 up to a higher level, and with a JN'.JST.W. dip they spread over the 

 tract east of Farmer's and Hillaby, which extends to Mount Hillaby, 

 the highest point of the island. Here there are cross faults, and the 

 dips on Mount Hillaby are eastward. The tract is bounded on the 

 north by a powerful fault, which completely cuts out the white 

 earths and brings up the Scotland Sandstones. 



The next tract of the Oceanic Beds is brought in by a fault which 

 runs from below Spring MiU to Swann's estate in a JS'.E. direction. 

 This tract is a mile wide along the line of the fault and extends for 

 about 24 miles to the north, but as the beds dip steadily to the 

 south-east the base rises northward, while the base of the coral-lime- 

 stones descends, so that eventually the exposure of white earths is 

 reduced to a very narrow strip. 



Below Prospect, however, a wider area of them is again brought 

 in by a fault which strikes nearly due east and west, with a down- 

 throw to the north. In this area the dip is also to the south-east, 

 and, like the last, it narrows northward from Cleland and Bredy's 

 till its base finally passes beneath the descending coral-rock escarp- 

 ment near Mount Stepney. 



Once more are the Oceanic Beds brought in by a downthrow 

 about half a mile from Grant's Bay, where they are exposed in the 

 cliffs and pass under the coral-rock by the promontory known as 

 Pico Teneriffe. 



(b) Sublying Areas. — The tracts which have been mentioned 

 are those which emerge from beneath the escarpment of the coral- 

 rock. They are, of course, portions of larger areas, parts of
