 the salt is allowed to recrystalise. The fresh salt is 

 washed in the brine and piled in heaps, each heap being 

 reckoned to be about 200 maunds in weight.

All these dhands with the exception of Bangrio contain C0 2 

 equivalent to less than half a gram per litre of Na 2 C0 3 . 

 The amount of C0 2 in Bangrio works out at 1*2 grams of 

 Na 2 C0 3 per litre. I have not reproduced that part of 

 the Sind map which shows the position of these dhands, 

 since they are outside the alkaline area. 



Samples of brine from the following dhands in the Diplo and 

 Mithi taluqas in the south of the Thar and 



Dhands of the Diplo p ar k ar district were sent to me by the

From the foregoing account of the dhands of Thar and Parkar, 



it is now apparent that this area has been 



Summary. desiccated to a considerable extent since the 



canalisation of the Nara, so that without exception all the dhands 



worked for chaniho previously to 1899 are now dry, and can never 



yield again. Moreover, of the large dhands such as Sangriam, 



Badahu, Jakrao, etc.. some are dry, and some are mere remnants of 



their former size. 



It is clear also that the ancient limits of the alkaline region did 

 not extend south of the latitude of Khipro, the most southerly 

 dhand, Dabhiwari being highly saline. At present the most southerly 

 alkaline dhand is Khari dhand in the S.E. part of Sanghar taluqa.

 Sukiawari, Nirawal, BahanwarL and Gari, all being small dhands and 

 all containing excess of chloride over carbonate. Khari. however, has
