SALT. 



445 



Sea water is generally composed of: 



Chloride of sodium 2 50 



Chloride of magnesium 0.35 



Sulphate of magnesia 0.58 



Carbonate of lime and carbonate of magnesia ... 0.02 



Sulphate of lime 0.01 



Water 96. 54 



Total 100.00 



with generally traces of iodide and bromide of magnesia. 



The following table is taken from the First Annual Report Animal Indus- 

 try, 1884, Washington, D. C, p. 490, showing the composition of the differ- 

 ent salts in the market, and will serve for comparison with Texas salts:

"In 1887 the production of salt in the United States was 7,831,962 bar- 

 rels of 280 pounds each. Of this the value was estimated at $4,093,846. 



" Michigan produced 3,944,309 barrels; New York, 2,353,560 barrels; Ohio 

 and West Virginia, about 600,000; Kentucky, Tennessee, and Virginia, about 

 200,000; or about 7,000,000 barrels in all produced from the evaporation of 

 brine. In addition, Louisiana praduced 225,000 barrels from quarries of 

 rock salt at New Iberia; Utah, 325,000 barrels, mostly from the waters of 

 Salt Lake, but a small portion from the quarries of rock salt in Jaub and 

 Sevier counties. California produced in former years over 200,000 barrels, 

 chiefly from the evaporation of sea water in San Francisco Bay, but in 1887 

 the production was only 28,000 barrels. 



" In Kansas a discovery of rock salt has recently been made which prom- 

 ises to be an important addition to the resources of the State. The Salt Beds 

 lie near the base of the Trias, and occupy a large area in the southern por- 

 tion of the State, extending into Texas. In seven localities cited by Mr. Rob- 

 ert Hay, in the Biennial Report of the Kansas State Board of Agriculture, the 

 rock salt lies at depths varying from four hundred and fifty to nine hundred 

 and twenty-five feet, and the thickness is from seventy-five to two hundred 

 and fifty feet.
