390 SORGHUM, 



pear, that a per eeut of sugar may be recovered from the bagasse nearly 

 equal to that which is expressed in juice even by our best mills. 



After this leacliing, the bagasse may be used for fuel or for the 

 manufacture of paper pulp, and for this latter use the exhaustion by 

 water increases its value. 



Edimatefor a Diffusion Leach. 



The following estimate is based upon the experiments recorded 

 above, and would suffice for a mill grinding about 2^ tons of cane i^er 

 hour. 



A mill expressing 60 per cent of juice, would furnish 2,000 pounds 

 of bagasse from 2^ tons of cane. 



2,000 pounds of bagasse would occupy 125 cubic feet of tank-room, 

 and the tanks filled with bagasse would require 113 cubic feet (848- 

 gallons) of water to fill them. 



To take 2,000 pounds of bagasse per hour, would require two tanks, 

 each of 62^ cubic feet capacity, or of the dimensions 3^ X 3^ X ^ 

 feet, and would require every hour 848 gallons of water. If the dif- 

 fusion of the bagasse is completed in three hours, then 6 tanks would 

 be filled before the first would be empty, and 8' tanks in all, with 12 

 steps on which to place them, would suffice. 



ANALYSES OF SORGHUM LEAVES. 



In the following table is given the analyses of the leaves of four 

 varieties of sorghum, and of the juices expressed from the stalks from 

 which the leaves were taken. There is in the dried leaves an average 

 of 5.41 per cent of total sugars, while , the average amount of total 

 sugai'S in the juices from the stalks is 14.44 per cent. 



As has been shown in another place, there is an increase of about 6 

 per cent in the amount of syrup, and a decrease of about 6 per cent in 

 the amount of the available sugar obtained when the stalks are passed 

 unstripped through the mill, instead of using stripped stalks. 



But it will be seen that these leaves have a composition v.hich shows 

 them to be of very great nutritive value, and, as fodder, they are well 

 worth preserving whenever one strips his cane for the mill. Indeed, 

 their value is such that, if carefully preserved, they would easily repay 

 the cost of stripping. ■ 



For purpose of comparison, the following average analysis repre- 

 senting the composition of five samples of hay, are given (A), and the 

 average composition of a large number of American grasses (B), given 

 in the Report of the Department of Agriculture f )r 1879, pages 112, 

 123. The average of the four varieties of sorghum leaves is given 

 in (C).
