Vol. 6$.^ THE CORAL-ROCKS OF BARBADOS. 321 



The cutting made through Conset Point enables the railway 

 to descend from the level of the plateau, about 120 feet, to about 

 50 feet above sea-level. The cutting follows a long curve for about 

 3 furlongs to the west of the eastern cliffs and to the south-west 

 of the northern cliff. Along the south-west of the curve it has 

 been found necessary, from time to time, to set back the cutting, 

 owing to the frequent occurrence of slips in the masses of limestone. 

 As a consequence of a recent retirement of this cutting, sections are 

 now exposed which were not available when I made my earlier 

 examinations of the district. 



About 800 yards north of the 14-mile post on the railway-line, 

 sections are exposed on both the eastern and the western sides of 

 the track. These sections are about 60 feet above the cliff-face 

 which shows beds apparently inclined at 6° to the east-north-east. 

 At the northern end of the sections the lowest beds seen dip 

 north-westward at 12°; these are succeeded by beds dipping at 

 33° north-north-eastward ; these by others sloping at 32° north- 

 north-westward, followed by some inclined to the north-north-east 

 at 15°, which underlie some 10 feet of beds dipping at 30° 

 eastward. These last have an eroded surface, and are covered in the 

 southern part of the section by practically horizontal beds. This 

 section was clearly shown at the time of my visit to be through a 

 series of diagonally or false-bedded strata, consisting for the main 

 part of consolidated coral-sand and rubbly limestone-debris, known 

 locally as < Marl/ (See fig. 3, p. 322.) 



Following the railway along the south-western part of the curve, 

 above and in the rear of the cliff-face where the beds seem to be 

 inclined to the south- south-east at an angle of about 27°, a section 

 some 30 yards in length is exposed, its direction being east- 

 north-east and west-south-west. In the upper part of this the beds 

 either are practically horizontal, or dip at low angles of 2° to 3° 

 east-north-eastward. These are underlain by marly and rubbly beds 

 dipping east-south-eastward at angles varying from 14° to 16°, 

 in which diagonal bedding is clearly apparent. (See fig. 4, p. 322.) 

 Some distance to the west of the foregoing sections a new cutting 

 has been made in a south- south-westerly and north-north-easterly 

 direction through the low hill called My Lady's Hill (marked 

 ' Rock ' on the official map of the island). This section is about 

 50 yards long, and about 20 feet high at its deepest part. Its base 

 consists of beds of calcareous sands and rubble dipping to the north- 

 east at 12° ; these are succeeded by beds dipping east-north-eastward 

 at angles of about 15° to 16°; while the top beds of the section 

 are practically horizontal. The varying dips are due to diagonal 

 bedding, and their general direction is north-easterly. This section 

 shows numerous small faults, fissures, and cracks apparently due 

 to landslips, (See fig. 5, p. 322.) 



The cliff- and railway-sections described formed the basis on 

 which Prof. Spencer constructed the section (here reproduced, fig. 6, 

 p. 323), given on p. 358 of his paper, and described as follows : — 



' We find the accompanying section (fig. 1) in the railway-cutting and bluffs 

 near Ragged Point.'
