outcrops in the channel of the river, rather than by quarrying or 

 mining it at some other point is abundantly proven by the fact 

 that watcr-vi'orn splinters and chunks with the grooves, channels 

 and pockets worn by the erosive action of flowing water and sand 

 may be picked up on village and shop sites which are many miles 

 distant from Webbers Falls. Whether implements of this material 

 may be found in the remains of all prehistoric cultures of the region 

 in question has not been determined. 



It would be interesting to know if rock of this stratum can be 

 quarried in unfractured slabs, for, if so, it might have considerable 

 value in the manufacture of furniture and interior architectural 

 finish.
