The analogy of composition with sea- water is certainly strik- 

 ing. I believe that most kinds of rock-salt contain much less 

 muriate of magnesia, which gives to sea-water its disagreeable 

 flavdur.t 



The process of converting the brine into salt is worthy of a 

 brief description. The expense of evaporating by fire so weak 

 a brine, would evidently be too expensive to be profitable, in a 

 country destitute of mineral coal. The well known plan of 

 suffering the water to drop from twig to twig, off vast open 

 stacks of thorns, arranged so as to expose as much surface as 

 possible to the air, and thus evaporating it at common tempe- 

 ratures, is therefore resorted to. The water is pumped from 

 the well by eight pumps or fewer, depending on the dryness 

 of the weather, to the top of a vast wooden shed which contains
