252 On the Manufacture of Bait in India. 



the difference between the Bdhdrbung and the Tuffaul salts. 

 The interruption of the fires in the one case, and the conti- 

 nued evaporation in the other, it is natural to suppose might 

 produce some difference in the character of the salt. A 

 large-grained, hard, but impure salt, forms by solar evapora- 

 tion from the mother liquor, near the place where it drips 

 from the baskets in which the impure salt is placed to dry. 

 This is equivalent in this stage of the process, and the circum- 

 stances under which it is formed, with the cat salt of Lyming- 

 ton salt works, and might, by allowing the salt to drip over 

 stakes, as at Lymington, be rendered a highly valuable 

 salt for packing provisions. Cat salt is obtainable in the 

 proportion of one per cent, of the whole. The cat salt 

 in the Bengal manufacture is allowed to deposit in the bit- 

 tern or mother liquor, and hence, from its impurities, it is 

 returned again to strengthen the brine. It might be very 

 useful to endeavour, by simple application of stakes driven 

 into the ground, to eonvert this variety into salt calculated 

 for packing provisions, and also to know in what quantity it 

 is formed during the season, and how far its quantity and 

 purity might be increased or improved in India.
