The dip of the conglomerate floor, on which the basalt rests, is 

 W. 30°, N. at 10°. It is clear that the conglomerate and basalt 

 occupy a small trough in the granitic rock, as a few yards further 

 down the creek the base of the conglomerate rises gradually to 

 10 feet above the bed, while going up stream we ascend to 60 

 feet above the sea before we again find basalt on the floor, its 

 base rising more rapidly than the stream bed. At about half a 

 mile from the mouth the creek bed is 80 feet above sea level, and 

 a good section (Fig. 4) shows a clifi" of 30 feet of basalt overlying 

 the granitic rock without the intervention of the sands and 

 conglomerates. From this point upwards the course of the stream 

 for some distance has a very gentle fall, granitic rock occupying 

 the bed for the whole distance. At 90 feet above the sea the 

 section displayed (Fig. 5) shows 1 5 feet of granitic rock overlain 

 by 20 feet of a conglomerate, chiefly composed, as are the others 

 under the basalt here, of pebbles of slate and quartzite. The 

 surface of the granitite (?) is uneven, and, at a height of 120 feet, 

 we find decomposed basalt in the creek bed, which is again 

 succeeded, as we ascend the valley, by the granitic rock. 



At about 180 yards from the road, and at a height of 160 feet, 

 we reach the top of the last granitic outcrop, and between this 

 and the road, at a height of 230 feet, we find only ferruginous 

 grits. The top of the granitic rock is much weathered, and, as 

 the base of the grits much resembles it, an exact line of 

 separation cannot be drawn. The ferruginous grits, at an 

 elevation of 190 feet, have yielded obscure plant remains. 



South of Grice's Creek. 



On passing southwards from the mouth of Grice's Creek we 

 find the Marine Eocene dipping south at about 25°, but a change 

 of direction to the north .soon takes place, and the calcareous 

 bands can be seen striking out to sea in a westerly direction
