Tobacco is invariably grown where khdrd pdni or saline water is obtain- 

 able. Where it is not, the necessary salts are provided 

 by dressing with " nona matti" the earth collected 

 from the bottom of walls and streets in villages. 1 



The virtue of khdrd pdni is due to the presence of nitric acid resulting 

 from the decomposition of ammonia. The ammonia has its origin in the fact 

 that khdrd pdni is found in wells sunk on the sites of deserted villages or forts, 

 where, from the habits of the country, the soil has become saturated with urine, 

 or much mixed with decomposed organic matter. 



1 Lond (=nond), or the oxalic acid collected from the leaves of gram, is much used in the 

 preparation of nitric acid (leste Elliott).
