From the above results it will be seen that, as the average of 2,348 

 analyses of over 100 varieties of sorghum, and during a period of four 

 successive years, there was fiund in one ton (2,000 pounds) of sor- 

 ghum by exponent 118.3 pounds of sugar available, and by difference 

 103.6 pounds; while in the several years the results were as follows :

It would appear, therefore, clearly established, as the result of all 

 these analyses of nearly every variety of sorghum known, that, with 

 our ordinary mills, we may secure from every ton of stalks, if Avorked 

 at the proper time, at least 110 pounds of sugar; a result fully equal 

 to the average secured from sugar-cane in Louisiana.
