OCCURRENCE OF PRECIOUS STONES IN N.S.W. 247 
Herewith is an analysis of a topaz from Emmaville, to which 
are added for the sake of comparison the figures for a Tasmanian 
topaz, extracted from Dana’s “‘System of Mineralogy.”?

GARNET. 
It would be hard to find a district in the Colony where garnet 
in one variety or another may not be found. Massive garnet 
rock is not uncommon. A garnetiferous lode was found gold- 
bearing and worked with profit near Molong. Massive garnet is 
found near Minore Railway Station. Masses of magnetic iron 
and garnet are found near Binalong. Garnet rock must occur in 
abundance in the Tumut district. Numbers of samples are 
collected by miners and prospectors. Professor David first 
recorded the exact localities for garnet in the Emmaville (Vege- 
table Creek) district, as for example, at Boiling-Down Creek and 
Patterson’s Reef.2 Garnet fit to be classed as a precious stone is 
not common. Certainly no garnets have been found here to 
compare with the stones from the MacDonnell Ranges, or with 
those occasionally sent down from Queensland. The best garnet 
I have seen in situ occurs near the Tamworth-Bingera road, — 
twelve miles from the last-named town. This locality was. 
examined by the writer in 1892. A note by Mr. D. A. Porter® 
referring to the same place, speaks of the garnets as lying on the :
