We are iiifoniied that bones of whales were found here when 

 the cutting was made, and that they were sent to Professor 

 McCoy, but we cannot vouch for the statement ; we saw no 

 signs of any. 



As may be gathered from a preceding remark, the eocene 

 shells are most frequent in the lower part of the section, and 

 this is specially the case from the base to about two and half 

 feet up, but they also occur, tliough more sparingly, at a higher 

 level. Moreover, at the foot of the clitF we were unable to find 

 miocene fossils by digging, though they are plentiful enough 

 above, and show here and there on the face all the way down. 

 At tlie height just mentioned, viz., two and a half feet up from 

 the road, there is a layer of sandy clay, mixed with magnetic 

 iron oxide and titanic iron, running horizontally along the 

 section, and it is possible that this may mark the actual line 

 of contact between the upper and lower beds. Certainly, the 

 strata beneath it, which consist mainly of a tolerably compact 

 limestone similar to that on the cliffs of the Mitchell River, 

 furnished nearly all the eocene fossils on our lists. 



The cutting is about eighty yards long and slopes gradually 

 at either end. In its deepest part it measures about forty-two 

 feet from the road at its foot to the summit, to which may be 

 added twelve feet of alluvium on the river bank just below. 



The following are appi'oximate measui'ements of the strata, 

 which are arranged in horizontal layers :
