The Bellevue bank, as measured l)y levelling from Captain 

 Underwood's doorstep, is 146 feet above the river level. (See 

 Figs. 4 and 5 for sections at Bellevue). A section exposed on the 

 face of the cliff overlooking the river gives : — 



Ferruginous blocks, with miocene fossils 



Clay 



Limestones (eocene), with fine gravel 

 Yellow limestone (burnt for lime) 

 Alternate beds of hard and clayey limestone, 

 with eocene fossils - . . . 

 Talus to river level . - . - . 



Total 140 feet. 



A little back from the cliff and on the slightly sloping bank, a 

 heavy gravel wash shows in a quarry, referred to below, and then 

 farther up still a ferruginous sandy conglomerate. The fall of 

 the river from Underwood's down is very slight, the surface of 

 the water at the section quoted, being only six feet above sea level. 



There is a deep gully close to the house, and a section across it 

 is given in Fig. 4. On both sides the hard calciferous limestone 

 can be seen outcropping here and there among the grass, until 

 towards the summit the overlying fossiliferous ironstone and 

 heavy gravel wash successively appear. 



The quarry shown in Figs. 4 and 5 was excavated to obtain 

 gravel for road making, and at its base a portion of a fossilized 

 tree three feet long, and two feet in diameter, was uncovered. 

 The log has not been removed, and was thus seen by us /« si'/u. 

 It is coated all round with ferruginous gravelly material to a 

 thickness of some inches, while the internal part consists largely 

 of decayed vegetable matter. The top of the quarry which is 

 13 feet below Bellevue House, and therefore 139 feet above sea 

 level, represents nearly the highest point at which miocene casts 

 were obtained. The hou.se is built on the river terrace and not 

 on the summit of the bank, which is reached by a gradual slope 

 at a further height of 105 feet. The strata consist mainly of 

 gravels, sands, and clays, with here and there ironstone blocks 

 enclosing pebble.s, but apparently unfossiliferous. The same 

 remark applies to ironstone at Clifton, near at hand, and also to
