of the juice at the two periods; they are given in the following table, 

 together with the length of time the cane was allowed to stand. The 

 available sugar is calculated upon the formula of sucrose minus one and 

 one-half times the glucose : 



Table shoiving improvement in cane by ripening. 

 STORE CUT. 



Average improvement per day in pounds per ton, . 85. 

 BOYLE CUT. 



Average improvement per day in pounds per ton, 1.6. 

 CLAKA CUT. 



Average improvement per day in pounds per ton, 2. 13. 

 SILLAN CUT. 



Average improvement per day in pounds per ton, 1. 71. 

 Average improvement per day in pounds per ton for all four cuts, 1. 56. 



It will be seen that the improvement in the juice was remarkable in 

 every case, although the longest period allowed to elapse bet ween the first 

 aud second analyses was only sixteen clays. The per cent, of sucrose, 

 and the purity coeflficent are greatly increased, and the per cent, of glu- 

 cose diminished. Calculated out in a practical way to show the increase 

 in available sugar which would be obtained at 70 per cent, extraction, 

 one plat shows as high as 23 pounds per ton for a period of eleven days. 

 With a greater extraction the increase would be much more. The av- 

 erage increase of the four plats is 1.5G pounds of available sugar per 

 ton for each day the cane was allowed to stand. Thus, a crop of 10,000 

 tons would improve at the rate of 15,600 pounds per day of pure sucrose, 

 equal to at least 16,500 pounds of merchantable sugar, so that two weeks
