Four of the twelve preceding Septembers had a greater mean rainfall, 

 viz, 7.85 inches. Eight of them had a less mean rainfall, viz, 2.58 inches.

On September 10 I found the greater number of seed heads of the 

 Early Amber cane ripe and the seed quite hard. A few of these canes 

 were cut, the juice expressed and analyzed. The result of the analysis 

 showed a percentage of 9.17 sucrose, and 4.83 of other sugars. 



In spite of this discouraging outlook, I determined to begin opera- 

 tions at the mill, in order that the experimental season might be as long 

 as possible. A few tons of cane were brought in on the 11th of Sep- 

 tember, and on the morning of the 12th I began milling. 



IVIETHOD OF OPERATIONS. 



In order that the analyses might represent the average composition 

 of the canes, the samples of juice were taken directly from the receiv- 

 ing tank when it was full. I was convinced that however interesting 

 ' and valuable from a scientific point of view the analyses of selected 

 canes might be, yet they would never give to the farmer and manufact- 

 urer data upon which it would be safe to base the results of large field 

 and mill operations. I therefore considered it to be of first importance 

 that the analytical work should represent precisely the character of the 

 operations taking place at the mill.
