dip in the 800- to 1100-foot plateau-district are current- or false- 

 bedded, and are such as would naturally occur at places on, or near 

 to, the escarpments of a rising coral-island. 



A long series of exposures was followed from Castle Grant in a 

 north-westerly direction to the north-west of Mount Misery, a 

 distance, as the crow flies, of about 3 miles. 



From Little Island and Castle Grant to Niccolls the limestone- 

 beds are practically horizontal. The limestone of the long low 

 cliff, which extends in a north-westerly direction from Niccolls to 

 Chimborazo, a distance of about three-quarters of a mile, dips at 

 about 3° eastward near Mccolls, while for a short distance not 

 far to the west of that place it has a local dip of 18° north-eastward. 

 Prom here to a little west of Sugar Hill the inclination of the 

 beds is, for a short distance, at a low angle of about 2° to the east, 

 changing to one of a similar angle to the west-south-west. "West 

 of Sugar Hill the inclination becomes one of about 3° east-south- 

 eastward. A long synclinal curve extends from near here to 

 Chimborazo, the beds dipping west-north-westward in its eastern 

 part, lying almost horizontally towards the middle, and dipping 

 east-south-eastward in the north-western part of the section : the 

 angles of inclination not anywhere exceeding 2° to 3°. The small 

 limestone-plateau, upon which Chimborazo House is situated at an 

 elevation of 1100 feet, lies on the upper red clays of the Oceanic 

 Series and dips south-eastward at 4°. Between Chimborazo House 

 and Canefield the limestone-beds are nearly horizontal, or dip 

 southward at low angles of from 1° to 2°. 



North-east of Canefield is another example of current-bedding, 

 beds dipping at from 2° to 3° south-eastward lying below others 

 which slope south-westward at 10°. 



At Mount Misery, a little to the north-west of Canefield, the 

 limestone, which there is not more than 20 feet thick, is seen at 

 an elevation of about 1070 feet lying upon an eroded surface of 

 Oceanic red clay which dips south-eastward at 27°. The mass of 

 the coral-rock slopes to the east-south-east at about 4°. On the 

 northern side of the hill the coral-rock slopes to the south-south- 

 west at angles of from 4° to 5°, while on the eastern face the bedding 

 is apparently at an angle of 9° south-south-eastward ; but this part 

 of Mount Misery is a slipped mass, and the considerable south-easterly 

 dip does not represent the original position of the limestone-beds. 



The limestone-beds appear everywhere on the 800- to 1100-foot 

 plateaus to lie practically horizontal, except in the places that I 

 have indicated, and none of these supplies evidence of the existence 

 of a widespread formation inclined at angles of from 12° to 20° 

 south-eastward. 



The South- Western District. 



There are few indications of dipping-beds in the road-cuttings 

 from St. John's Church to near Bridgetown. The only well-marked 

 beds of the kind that I saw are to the east of Locust Hall, at about
