 periment Station at Berkeley, at a nominal cost. 

 The phosphate rock on this Coast is too rich in 

 limestone to be worked, and the southern States must 

 be given credit for more than 99 per cent of the 

 production of this entire country. There are a 

 number of fertilizer works, some producing their 

 own sulphuric acid. Most of the packing houses 

 and abattoirs are putting bone meal, dried blood 

 and tankage on the market. The bone and fertilizer 

 works are at present the sole producers of sulphate 

 of ammonia. 



Carbonic Acid. — The manufacturers of liquid 

 carbonic acid gas have again commenced using 

 magnesite rock. For a time the calcined magnesite 

 could not be sold and the companies were forced to 

 use limestone as there was a ready sale for the 

 quick lime. 



Cream of Tartar and Tartaric Acid. — The Cali- 

 fornia wine industry does not furnish sufficient 

 lees and crude argols for the one factory producing 

 cream of tartar and tartaric acid, and raw goods 

 have to be imported. It may be said that the en- 

 tire output of this factory is made into baking 

 powder. 



Tree Sprays, Insecticides and Copper Sulphate. 

 — ^A number of different companies are manufac- 

 turing tree sprays, insecticides, deodorizers, sheep 

 dip, etc. Some nave small plants while others are 

 a part of a large factory. One large establishment 

 producing acid from pyrites contrives to save some 

 of the arsenic and utilizes it in the manufacture 

 of insecticides. A smelting works on the bay saves 

 all its copper in the ores as bluestone or copper 

 sulphate. 



Barium Products. — There are a number of de- 

 posits of barytes in California and the production 

 for 1913 amounted to 1600 tons, this being prin- 

 cipally used for, and as an adulterant of, white 

 lead paint. One company is producing barium 

 peroxide which in turn is used for producing 

 hydrogen peroxide. 



Mineral Resources. — A great many mineral re- 

 sources are identical with the chemical resources 

 of the locality. Mineral spring waters, and there 

 are a great many in the State and some of decided 

 medical value, if evaporated and the salts brought 

 on the market would come under the latter class. 

 In 1913 there were produced 2,350,792 gallons of 

 mineral water, actually bottled and sold and the 

 greater part for drinking purposes. 



Metallurgy is the chemistry of those minerals or 

 ores yielding metals; but when metals are won as
