The available sugar from one ton (2,000 pounds) of maize stalks was, 

 in 1880, by exponent method of estimation, 83 pounds, a ditfereuce 

 between sucrose and other solids of &() pounds; in 1881, from 2,000 

 pounds stalks, by exponent, 92 pounds, a difference of 77 pounds be- 

 tween sucrose and other solids. 



The results by polarization of the above maize juices in 1881 was 

 92.6 per cent of the results obtained by analysis. 



The Hydrometer and Ripe Seed Sufficient to Indicate the Proper Time for 



Working the Crop. 



It will be seen, by reference to the preceding tables, that it is within 

 the means of the common fanner to inform himself accui-ately as to 

 the condition of his crop by simply examining the seed, and by 

 the hydrometer learning the specific giavity of the expressed 

 juice. 



For each increase of .001 n specific gravity between 1048 and 1086, 

 in the year 1880, there was an average increase (glucose excepted) in 

 the several constituents of the juice of the several sorghums as fol-
