" The cassiterite of Mt. Bischoff is associated with topaz, both crystalline and 

 amorphous, in large dikes of an acidic porphyritic rock penetrating slate and sand- 

 stone. The topaz has replaced feldspar, the rock containing no alkali, and consisting 

 practically of quartz and topaz. It is comparable to the Saxon ' sneckenstein,' a 

 topaz quartz-porphyry. ' '

" Tin ore was found in Tasmania at an early date in the history of the colony, but 



it was not until 1872 that the great Mt. Bischoff property was discovered The 



tin is found in what is termed euritic porphyry and the most productive portions of 

 the deposit are situated close to the porphyry and slate." 



The next district in importance is Ringarooma. The deposits at this place appear 

 to be the bed of an ancient river running nearly north and south and are covered 

 by a crust of basalt.
