221 COTTER: SODA INDUSTRY OF SIND. 



the remaining three dhands are small and unimportant. I have 

 stated that the season's output from Mithri was estimated at G,000 

 maunds. 



Having described the soda yielding dhands west of the Nara, I

west of Nara. which, although alkaline, never become 



sufficiently concentrated to yield trona, 



and have never become producers. I have not attempted to make 



a complete list of these dhands, some of which are not marked on 



the map. A full list could only have been made by a complete 



survey of the whole country, which would have greatly extended 



my tour. I give a list of the alkaline dhands seen in the course of 



my survey of the producing dhands. This list, though not complete, 



contains all the more important dhands, with analyses of the water 



in the case of the larger ones. 



Of the dhands already described, three properly belong to the 



class now about to be described, viz., Khariri, Virchora, and Pharan- 



wari, because these three have never themselves yielded chanilw, 



which has only been collected from pools at their margins. Khariri 



and Virchora are the largest of the alkaline dhands. Analyses of 



their waters will be found in Chapter VI. Commencing with the 



rn^et northerly, the list is as follows : — 



(1) Bhitrawaro dhand, west of and close to Bagarwaro, is 



about 3 furlongs in length, and contains brackish water 

 probably not very highly concentrated. 



(2) Bitrewari dhand, between Sukchaho and Chughari Chahe- 



wari, is a brackish nearly circular dhand about J mile in 

 diameter. 



(3) Khariri, already described. 



(4) Pir Naga or Pir Nanga, 1 mile S.E. of Khariri, is an almost 



fresh water dhand ; specific gravity 1-002 ; alkalinity 

 calculated as sodium carbonate 1-2 grams Na 2 C0 3 per 

 litre. 



(5) Nichora, a small narrow dhand, \ mile in length, north of 



Virchora with brackish water. 



(6) Virchora, already described. 



(7) Pbaranwari, already described. 



(8) Dillahuwari, a large dhand 1 mile long, half a mile broad 



to the south, narrow in the north, situated 1 mile south 

 of Virchora. The water of this dhand had a specific
