REPORT ON SUOAR PRODUCTION FROM MAIZE. 



samples consisted of 24 stalks each and were taken the morning of 

 the day the analyses were made. As soon as cut they were sent to 

 the Bureau of Chemistry, where the juice was immediately extracted 

 by running once through a 3-roller mill. The following analytical 

 determinations were made of this juice: (1) Solids by Brix spindle, 

 (2) direct and invert polarizations, (3) sucrose by Clerget, (4) invert 

 sugar before reduction, and (5) percentage of moisture in the sample 

 of cane as originally received. The purity of the juice — that is, the 

 percentage of sucrose divided by the solids — was calculated from the 

 data thus obtained. The results are presented in Table II, the sum- 

 mary of which shows the changes in composition of the juice follow- 

 ing the removal of the ears.
