This well furnishes about 13,000 gallons of brine in 24 hours, 

 ranging in strength from 15° to 80° by the salometer. Ac- 

 cording to Dr. H. C. Potter, Superintendent of the works, the 

 brine is treated in the following manner: "We get a depoaite 

 of iron in our settling vats, first, by putting the brine into them 

 heated, (running it through a heater,) and, second, by using on 

 each 21,000 gallons a pailful of lime. We are trying experi- 

 ments to settle with other materials. In the kettles we used 

 alum for cleansing for a time, but recently, and since cold 

 weather, we have used nothing. The chlorides can only be 

 removed by bailing out the residuum, after say the 5th to the 

 8th drawing of salt, when the bitter water accumulates to such 

 an extent as to act on the iron of the kettle, and rust the brine 

 and the salt. This course, of throwing out the bitter water, is 

 adopted in Kanawha, Va., and Pomeroy, Ohio, where the brine 

 resembles ours in chemical composition, and though an expen- 

 sive one in loss of brine, seems the only one that is practicable. 

 ■* * * The impurities remaining in our salt, after having 

 been drawn from the kettles, are removed by drainage, being 

 liquid almost entirely. This thorough drainage is the essential 

 point in our manufacture." 



This company are engaging vigorously in the manufacture of 

 salt, both by solar evaporation and by boiling. They have 20 

 covers, 16 feet square, for solar evaporation, and 100 kettles 

 ■for artificial heat. They have produced to the date of thia
