Half a mile below, a similar road-cutting near Baker's gave us 

 another opportunity of seeing the nature of the beds clearly. 

 The valley hereabouts is of less depth than almost anywhere else, 

 being only about eighty feet deep. The marine beds are about 

 sixty feet thick, and pass up from gi'ey sandy marls into more 

 sandy beds with bands of hard, ringing, concretionary limestone, 

 and towards the top become moi^e fer'ruginous. The face of the 

 section is sparsely strewn with small quartz pebbles, but we 

 could not find any bed from which they might be derived. The 

 remaining twenty feet of the hill consists of the usual volcanic 

 capping, the rock being a rather coarse dolerite, judging by hand 

 specimens. Fossils were only obtained from the lower part of 

 the section, are not very common, and are of Eocene age.
