Gives a history of tin-mining in New South AVales; physiography, meteorology; 

 geology; mineralogy, etc. Much of the country is covered by basalt up to 300 feet 

 thick, averaging 200 feet. In places, stanniferous stream gravels covered by the basalt 

 have to be crushed before the tin can be obtained. 



Siluro-Devonian sediments are intruded by quartz felsite dikes and granite, probably 

 of Permian age. The tin deposits are associated with this granite. Tlie stanniferous 

 gravels both exposed and lava-covered are described in detail. Some of the stream tin 

 is only 1/70 of an inch in diameter but shows sharp crystal edges. Sapphire, topaz, 

 zircon, spinel, garnet, magnetite and ilmenite are found in the placers. Gold is also 

 found in small quantities. 



Ninety veins and stockworks are described. 



Quartz is found in 69 veins; chlorite in 29; feldspar in 20; mica and arsenopyrite 

 each in 8; pyrite and fluorspar, each in 4; tourmaline and wolframite, each in 3; 

 zinc blende, galena, chalcopyrite, bismuth, molybdenite, vesuvianite and stilbite, 

 each in 2; hematite, pj'rrhotite, manganese, scheelite and beryl, each in one vein. 



The veins range up to 3 feet in thickness. 



Gold, silver, lead and copper occur in veins of the neighborhood. Silver is in 

 commercial quantity.
