ends of each of the cuttings. Under the basalt comes a deposit 

 of ferruginous sandstone bands, sands and gravels, at times 

 passing irregularly into white sands, with here and there a few 

 nodules of hard quartzite just below the volcanic rock. The 

 texture varies from exceedingly tine, well-rounded sands to light 

 gravel, and a prolonged search for fossils in these cuttings 

 showed, as is so often the case in rocks of this character, that 

 organic remains are few and far between ; in fact, all we found 

 was the imprint of a single leaf, showing probably the fresh- 

 water nature of the deposit. On the northern slopes towards 

 the river, and at a lower level than these beds, the Quarter-sheet 

 notes " Ironstone full of fossils." These fossiliferous beds are 

 exposed in an old road-cutting leading down to the river, but 

 fossils are more plentiful in the loose blocks which thickly strew 

 the slopes below. The deposit is of esjsecial interest, as the beds 

 prove to be of Miocene age.
