aroo ! ! !, the lode is much decomposed, the galena can 
be picked out in nodules as big as a cricket ball, on 
cracking open these nodules, a zoned structure is seen 
consisting of carbonate of sulphate and oxide of lead in 
concentric layers, with perhaps a nucleus of clean fresh 
galena. In other cases the decomposition is complete 
and there is no trace of nucleus. I have seen such 
nodules in other galena lodes throughout the Tinaroo 
district, but they always occur in the lodes above
