In a horizontal direction there is a rather large and some- 

 what irregularly formed space between this uppermost terrace 

 and the preceding one. The material of this group proved 

 to consist of

The stones composing the material of this gronp were of a 

 rather different size, varying from that of a pea up to 115 mm. 

 It also vvas comparatively slightly worn. 



This uppermost terrace was highly interesting and had a 

 very fine appearance, as may be seen from the accompanying 

 plate I. Flint vvas here found both in grey-coloured and in 

 dark-coloured specimens. A lump of nearly black flint was 

 found, measuring no less than 165 mm. across. Syenitic stones 

 were not uncommon. Some boulders of agglomerate were 

 found in which layers of tufaceous material, sometimes resembling 

 a sandstone, might be traced alternating with others of a very 

 conglomeratic constitution. The structure, however, as also the 

 reddish-brown colour, is the very same as those of the neigh- 

 bouring base-rock.
