TASMANIA. 



The ifland of Flinders, off the north coast of Tasmania, is practically unknown 

 as a mineral locality except to a few Australian collectors. Yet a trip recently 

 made to the Island by a gentleman collecting exclusively for us, yielded 



GMELINITE 



In magnificent crystals whose size, perfection and beauty excel those of any 

 known examples of this rare species. They occur in cavities in a hard basalt, often 

 having a background of clear, gem-like Analcites. Associated with tufts of Natro- 

 Ute. they make rich and handsome specimens. They possess fine lustre and are 

 sometimes -f inch across. 



SPHAEROSTILBITE 



Occurs in minute but bright balls, scattered over Natrolite. and also as a thin, 

 transparent coating over primitive form Calcite crystals. 



NATROLITE AND ANALCITE 



in very pretty association. The clearness and brilliancy of the groups of the latter 

 mineral are unrivalled. 



Prices are low, as with zeolites from other localities. 50c. to $3.00 for fine speci- 

 mens, though the best of the G-melinites are 86.00 to $9.00.
