For a description of the native methods of refining the gur 

 and of the methods of making the various kinds of native date sugars 

 see page 359. 



YIELD OF GUR PER TREE. 



On page 325 it is shown that 170lfes. of juice per tree per 

 season may be taken as a fail average yield. So that the average 

 annual yield of gur per tree is 170/8 or 2r25lfes. 



Enquiries among intelligent cultivators seem to shew this figure 

 to be reliable. Three instances of these enquiries are given. From 

 120 trees one man produced 26 maunds of gur (pacca). This is 

 equivalent to just over 17lfos. of gur per tree. To this must be 

 added the amount consumed by him. A second man working with 

 8D trees reckoned he had produced from them 20 maunds (pacca) of 

 gur. This is equal to 23flb3. gur psr tree. A third man produced 

 Rs. 135 worth of gur from 180 trees. Included in this was gur, etc., 

 to the value of Rs. 35 consumed by his family. Rs. 135 is the 

 equivalent of about 4,320lbs. of gur. Therefore the yield of gur 

 per tree works out at 24ft>3. 



YIELD OF GUR PER ACRE. 



Three hundred and fifty trees could conveniently be grown per 

 acre, so that the yield par acre would be 350 x 21 Jibs, equal to 3'3 

 tons. Actually only 240 trees are usually grown per acre, and 

 this therefore equals 2*3 tons of gur which is still a much higher 

 yield than is obtained from cane in Jessore. 



It will now be of interest to quote the writings of various other 

 authors on the yield of juice and gur from date trees. 



Robinson 1 in some calculations of yields from date trees takes 

 the first day's yield per tree as 10 seers, that of 2nd day's as 4 seers, 

 and that of 3rd day's as 2 seers. This averages out at 5j seers of 

 juice per collecting day. Robinson moreover states* that his figures 

 are under rather than overestimated. From the preceding figures
