24. Altona Bay. 



A bore was put down, some particulars of which, with locality 

 plan, are published in the Report of the Secretary for Mines for 

 1894. Practically the same series of rocks was exposed as at 

 Newport. The thin sheet of volcanic rock however was overlain 

 by about twenty feet of post tertiary rocks, containing an abund- 

 ance of recent shells. The Marine tertiaries were about 160ft. 

 in thickness. Beneath the freshwater beds, the Government 

 report states that "45ft. lOin. fine white quartz-drift mixed with 

 shells " occurred. Unfortunately no sample of this interesting 

 deposit was sent to the department nor could we find any trace 

 of it when visiting the locality. It was probably too incoherent 

 for a core to be drawn, so that the interesting question as to 

 what the fossils were will probably remain unknown as the bed 

 lies more than twenty feet below the brown coal seam. Silurian 

 was struck at 422 feet. 



The small amount of material, which consisted merely of drill 

 cores, which we had to work on prevents the list of fossils from 

 being larger. Some of the beds were very rich, and in some 

 places the core was quite full of siliceous sponge spicules.
