The facts just narrated do not, in any way, point to the general 

 accuracy of his section. The uppermost beds of the Conset-Point 

 plateau are certainly horizontal, or nearly so ; in place, however, of 

 the statement 'All of these beds dip 1-5° to 20° south-eastward' 

 (loc. cit.), by which he described the lower beds, it is only possible, 

 after careful and minute examination of the various exposures, 

 to state that the lower beds do not exhibit even an approximately- 

 uniform dip to the south-eastward, but incline in varying direc- 

 tions — as, for instance, to the east-north-east, to the south-south- 

 east, to the north-west, to the north-east, and to the east, while the 

 angles of the dip vary in the strata of the mass from about 12° 

 to 33°. The evidence shows that the Conset-Point mass is made 

 up of diagonally-bedded strata of consolidated calcareous sands 

 and rubble, the inclination of which in parts has been materially 

 modified by landslips and by tilting towards the sea. (See fig. 7, 

 p. 323.) 



The South-Eastern Sections. 



Prom Conset Point in a southerly direction as far as The Crane, a 

 distance, as the crow flies, of about 5 miles, I examined many road- 

 and quarry-sections and bluffs on the coast. 



Prof. Spencer stated (op. cit. p. 358) that 



' the strike of these [that is, the lower — J. B. H.~\ beds continues to Three 

 Houses, 2 miles inland ' ; 



out the only section which I found at that place is the road-cutting 

 near Three Houses at Thicket Hill, through calcareous rubbly 

 beds curving in their inclinations from a dip of 2° to 3° east-north- 

 ■eastward at the south-eastern end of the cutting to a slope at 

 about the same angles west-north-westward near its middle, and 

 again east-north-eastward at a somewhat lower angle at the 

 north-eastern end of the exposure. (See fig. 8, p. 323.) 



The great mass of limestone on the escarpment to the north-west 

 of Three Houses is intersected by several deep gullies or ravines ; 

 and many low cliff-sections are visible in these, and on the face of 

 the escarpment. There are also, as near Pleasant Yale, some large 

 quarries in the lower parts of it. Wherever the rock is in situ the 

 bedding is either horizontal, or, as in the escarpment below District C 

 Police-Station, dips at low angles of about 1° to 2° westward. 



About Ij miles south-west of Three Houses, at B ushy Park, there 

 is a long and excellent series of exposures of dipping-beds for some 

 250 yards along a road-cutting running north-west and south-east. 

 The following beds are seen when going up the road from the south- 

 east : — A bed of rubbly coral-debris, 3 feet thick, dipping at 27° 

 south-eastward, which is exposed for about 5 feet, its dip gradually 

 decreasing to 18° where it is cut off by a bed 8 inches thick dipping 

 at 25° west-north-westward ; 30 feet to the north-west of this the 

 lowest beds seen dip at 3° south-westward, and are below others 

 sloping towards the east-south-east at 45°, which are in turn suc- 

 ceeded by beds dipping south-eastward at 5°. Some 30 feet from the
