wood. The drift on the West coast is mainly quartz of various 
varieties with fragments of wood transmuted to Marcasite—which 
on exposure soon decomposes to the sulphate. 
The principal localities of the mineral are, on the North West— 
Mt. Bischoff; Mt. Hicks; Meredith Range; Mt. Ramsay; Mt. 
Housetop; Blyth River; North Pieman; near Mt. Claude; 
Iris River, near Middlesex; Granite Tor; Ring River; North 
Dundas. On the North-east—Mt. Cameron; Moorina; Branx- 
holm; Mt. Stronach; Mt. Maurice; Weldborough ; Blue Tier ; 
St. Helen’s; South Freycinet Peninsula; Weld River; Mussel 
Roe River; Cascade; Derby; Mt. Horror; St. Paul’s; Ben 
Lomond. In Bass Straits—Flinders, Clarke, and Cape Barren 
Islands. In the South—Cox’s Bight, near Port Davey. 
~The economic results of our tin-mining industry have been 
highly satisfactory ; for although practical operations were not 
commenced until the year 1873, and lode-mining, with the exception 
of the celebrated Bischoff, has been comparatively neglected, it has 
now become our principal mineral product. 
Tin first appeared as a factor in our mining industry in 1873, in 
which year the total export amounted to four tons of ore valued 
at £220. From that period to the end of 1892 the export of the 
crude and smelted metal represented not less than 62,130 tous, 
valued at £5,599,467. 
The following statistics may be interesting as showing the 
quantity and value of the tin exported during the past ten years ;—
