and in the " Acid Granite " area (Table iii.), indicate that the 

 fracture-systems in these areas are also related to those of the 

 Tingha-Stanthorpe belt. The observations made on the lodes 

 and joints in the " Tingha Granite " (Table iv.) show that, though 

 the Elsmore system of fractures is represented, yet the main 

 lines of weakness approximate to east and west rather than to 

 north-east. As this east and west system is almost absent from 

 the " Acid Granite " belt, it is probable that the Tingha system
