to the bedding of parts of the rocks, I propose to 

 describe them in some detail. 



I spent some time in re-examining the coral- 

 rocks to the north-east, and south of Bridgetown, 

 including the exposures ' near the Cathedral,' whence 

 Prof. Spencer stated that he had obtained the 

 corals on which he based his opinion that the steeply- 

 dipping rocks some 10 to 12 miles away are of 

 Oligocene age ; but I failed to find any evidence of 

 the existence of limestones other than of recent or 

 Pleistocene origin. 



Conset Point and Railway-Cutting. 



Prof. Spencer described on p. 360 of his paper 

 a series of beds dipping uniformly south-eastward, 

 and succeeded by horizontal strata which he stated 

 were exposed in a railway- cutting and bluffs near 

 Ragged Point. There is not, and there never has 

 been, a railway -cutting in the vicinity of Ragged 

 Point, the nearest cutting being at Conset Point, 

 about 2| miles to the north-west of it. This, 

 doubtless, is the cutting seen by Prof. Spencer. 



Conset Point is an extensive mass of limestone, 

 bounded on its northern and eastern sides by high 

 rugged cliffs upon which the sea breaks with much 

 violence. The limestone near the base of the cliffs 

 has been extensively undermined by the waves ; 

 and there are great fissures running horizontally 

 through it, connected by vertical ones with the 

 surface, through which, when the area is rough, 

 the water is driven with great force, giving rise to 

 ; Spouts.' Viewed from the north-west, the eastern 

 part of the mass is seen to have been undermined 

 by the sea. and, assisted by the beds originally 

 sloping in various directions seaward, to have tilted 

 or slipped forward on the underlying clays of the 

 Scotland Beds exposed at sea-level in the adjacent 

 Conset Bay, giving rise to beds which apparently 

 dip at relatively -high angles in various directions. 

 It was not possible to get to the base of the cliffs, 

 and hence I could determine the apparent dips only. 

 At the Point the apparent dip is 6° east-north- 

 eastward, while south of it the beds apparently slope 

 at about 17° in the same direction (see fig. 1). In 

 a cliff facing northward on the northern side of the 

 Point, the apparent dip of the beds is about 27° 

 to the south-south-east. The sloping beds in these 

 cases are approximately from 30 to 40 feet thick.
