 metallic salts, that part of the industry may be 

 claimed by the chemist. In 1913 there was pro- 

 duced in this State 7592 tons of tungsten ore; still 

 a factory making incandescent electric light bulbs 

 obtains its entire supply of tungsten filament from 

 the East. All the chromite, 1180 tons mined in 

 1913, was shipped East. The old California pros- 

 pector sought only gold, and then silver and copper 

 and after that halted. The mineral riches of the far 

 West are only just being uncovered and will lead 

 eventually to all kinds of metallurgical and chemical 

 activities.
