which is pumped up after becoming- saturated. The grades of 

 salt known as common fine, common coarse, table, dairy, pack- 

 ers, agricultural and milling salt are made by artificial evapora- 

 tion of brines, the quality depending upon the methods em- 

 ployed and the degree to which the refining operations are 

 carried. 



In addition to the salt that is marketed as such, a very large 

 proportion of the annual output of the State is converted into 

 soda products by the Solvay Process Co. This company has a 

 plant at Solvay near Syracuse, where the preparation of soda 

 ash, carbonate, bicarbonate, etc., is carried on from brine that is 

 supplied by the company's wells in the town of Tully, 20 miles 

 south of Syracuse. The salt content of the brine thus used is 

 included in the production tables herewith. 



Altogether there were 31 companies in the State who reported 

 an output in 1907, or one less than in the preceding year. Of 

 the total number, Onondaga county was represented by 20 com- 

 panies, while the remaining 11 were distributed among the fol- 

 lowing counties : Genesee, Livingston, Schuyler, Tompkins and 

 Wyoming. The International Salt Co., the largest manufacturers 

 of brine salt in the State, operated four plants as follows : Ithaca 

 works, Ithaca ; Cayuga works, Myers ; Glen works, Watkins ; and 

 Yorkshire works, Warsaw. The Hawley and Warsaw works, at 

 Warsaw, owned b}^ the company were inactive. No new manu- 

 facturers have entered the list of producers during the year. 



The total quantity of salt obtained from mines and wells in 

 New York last year amounted to 9,657,543 barrels of 280 pounds, 

 on which a value of $2,449,178 was placed. This shows a gain 

 of 643,550 barrels, or 7 per cent, over the output for 1906 which, 

 was 9,013,993 barrels valued at $2,121,650, the largest reported 

 up to that year. Most of the increase was contributed by the 

 mines of rock salt, the output of wdiich is about one tliird the 

 entire total for the State. 



The accompanying tables show the production of salt dis- 

 tributed among the various grades. The output listed under 

 ''other grades " is made up principally of rock salt and salt used 

 for soda manufacture which arc combined so as not to reveal 

 the figures reported by the individual companies. A small 

 quantity of other kinds not specified in tlic rclurns is also in- 

 cluded under that item. The valuation ])laced on the salt thus 

 listed is much smaller proportionately than that of the other
