951. The Pachbadra salt is procured from pits dug 

 within what might be described as a former river-bed 6 

 miles in length by 2.V miles in width. 



952. The rock-salt of Northern India is excavated 

 chiefly from the salt mines of the Salt Range which extend 

 for 152 miles from the Jhelam to the Indus. There are 

 also salt mines in Kohat (trans-Indus) and the Himalayan 

 salt mines of the Mandi State. The salt from these mines 

 is obtained by pick and blast in the usual way with all 

 mining operations. The supply is practically inexhaustible 

 and the annual output is entirely dependent on demand. 

 The salt is of very pure quality and it is a good substitute 

 for Liverpool salt. The Mayo Mines of the Salt Range 

 produce about 75,000 tons per annum. 



953. Over a tract of country 15 sqr. miles in extent 

 South-West of Delhi, salt is obtained from brine wells. 

 This is known as Sultanpur Salt, which is somewhat bitter 

 owing to the admixture of sodium sulphate. A poorer kind 



still is made at Sankaransar, 50 miles north of Bikanir. 

 This is used for curing hides, for feeding cattle, and it is 

 also eaten by the poorer classes. In Orissa there is a 

 little salt manufactured under the Madras Salt Department. 

 The sea-salt is manufactured chiefly in the Thana District 

 of Bombay. The site chosen is usually on the shore of 

 a creek or estuary, below the level of high tides and 

 fully exposed to the influence of the prevailing winds. 

 It is first surrounded by high embankments, the enclosed 

 space being about 250 by 80 feet. The space so en- 

 closed is then divided by other walls into 3 sections, the 

 outer reservoir, the inner reservoir and the pan-area. The 

 space devoted to pans is carefully levelled and a floor of 

 clay repeatedly puddled until it becomes water-tight. The 

 pans are formed by small clay partitions two feet broad 

 which run the whole length and breadth of the pan-area, 

 crossing each other at right angles and thus forming a
