Geology of the Loiver MitcJtell River. 37 



a few chains farther west, is only accessible on foot when the 

 river is low, but it is, we believe, a more profitable bed for the 

 collector than the other. We reached it in the first instance 

 by means of a duck boat, a mode of conveyance we cannot 

 recommend to geologists, as by some mischance one of us was 

 suddenly tumbled headlong into the river. In addition to the 

 larger forms of mollusca the strata are replete with small shells, 

 corals, bryozoa, foraminifera, etc., which can be easily washed 

 out of the friable matrix. In both sections the shell beds are 

 at the base of the bank and under compact limestone, but in 

 contrast to Dreir's, the latter no longer constitutes the main mass 

 of the strata, alternations of sandy drift and ironstone occurring 

 up to the conglomerate capping at the summit of the terrace. A 

 drawing is given of the more westerly of these sections in Fig. 

 12, the strata observed being,

Total 95 feet. 



The river here is 46.55 feet above sea level. 



At another section, a little farther west still, the strata are 

 much the same, but the basal bed consists of 25 feet of the 

 calcareous material similar to that worked some years ago at the 

 first section, or Skinner's proper, when the majority of the fossils 

 listed below were collected. 



' In the half mile stretch between Skinner's and the gully, which 

 breaks through the banks westward, many good sections were
