Whale s Head and South Cape. 21 



To these sand-hills succeeds a natural embankment of 

 greenstone, — a prolongation, seemingly, of the eruptive 

 masses of the main-land into the Whale's Head pro- 

 montory. 



The locality now referred to is about north west from 

 the most southern projection of the Whale's Head, and 

 distant from it in a direct line three and a half or four 

 miles. 



The greenstone here forms, at an elevation of some 400 

 feet, a capping of unascertained depth over stratified 

 masses of shales, sandstones, and schistose clays, with 

 coal, which present to seaward vertical sections from 200 

 to 250 feet in height. 



There is a small island of igneous rock close to the 

 main, and almost accessible from it at low water, a little 

 to the south or S.S.E, of the cliffs I refer to : it is con- 

 nected by a narrow dyke with the greenstone overlying 

 the carboniferous rocks. 



Another dyke stands directly across the strand, like a 

 dark wall, and juts out into deep water, barring further 

 progress in that direction, except by scaling its almost 

 perpendicular side of 20 or 25 feet. 



The line of coast, and the dip of the carboniferous 

 strata, are nearly parallel, that is, south east; and the in- 

 clination of the beds is about 12°. 



The following is the long order of succession of these 

 beds, as nearly as I could obtain it, during a season of 

 very tempestuous weather, and in an exposed situation. 



There are several seams of coal ; the principal one, 

 called a 4-feet seam, proceeding from beneath upwards, 

 consists of 



Black shale 12 inches. 



Coal 18 ditto. 



Hard anthracite 3 ditto. 



Brown clay, soft and plastic 2 ditto,
