make-weight in our former estimates of Puckvvah. It will be seen in 

 the succeeding section, that we may assume a considerable portion of 

 Puckwah to be also produced in the manufacture of the Kharee, and 

 possibly some in the preparation of the Reher or Soda earths, for the 

 use of the washermen, soap-boilers, glass- makers, &c. &c. 



V. — Estimate of the quantity of edible Salt produced in the inanufac- 

 ture of the Phool-Kharee^ and of the quantity of Phool-Kharee an- 

 nually made. 



1. The production of the Salts called the Kars, Karees, and Dhars, 

 is a separate trade where earths are washed for these alone, and they 

 are also produced in the preparation of Saltpetre ; we may suppose 

 them not always thrown away when they form so large a per centage 

 as it will be seen they do. 



2. Dr. Buchanan says, vol. i. p. 366, that he estimates the production 

 of Dhar at 2 maunds of it to every 14 maunds of crude Nitre. This 

 is --th, or say 14;J per cent, which as we allow 2 maunds of crude 

 to make but one of refined Saltpetre, gives 281 per cent, upon every 

 maund of this article. 



3. Mr. Stephenson says, (p. 8), in his Analysis of the soil in 

 Tirhoot, that it contains nearly as much of the Sulphate (Kharee) as 

 of the Muriate and Nitrate together, but as we have before noticed 

 (p. 8) the Culinary Salt obtained from these two sources, I only 

 allude to them here. As a source of Kharee, they should be borne 

 in mind. Mr. Stephenson says, 2.7 of Sulphate and 3.0 of Muriates 

 and Nitrates. In Mr. Stephenson's paper, (Journal Asiatic Society, 

 vol. iii.) on the efflorescence of the Kharee, we find the best datum. 

 He says there, that the efflorescence collected by him gave 58 per 

 cent. Sulphate, (Karee), and 22 of Muriate of Soda ; so that, using 

 round numbers, every maund of Kharee from thence would give the 

 workman one-third of a maund of Puckwah. This, however, may have 

 been a richer spot than the average. Buchanan says, that some Muriate 

 of Soda is also found with the efflorescence of Carbonate of Soda, 

 (Rehar or Sajee MuttiJ ; but his work has evidently been sadly
