The highest per cent, of sucrose for the seasoii in the diffusion juice 

 was noted September 29, 10.02 per cent., being 2.30 percent, above the 

 average. The corresponding mill juice for the same date was 14.92 per 

 cent, sucrose, 2.5 above the average, showing that fair comparative 

 samples had been secured. 



The average during October was 8.59 per cent, sucrose, 1.74 per cent, 

 glucose, better than the results obtained at Lawrence, La., bearing in 

 mind the fact that the sugar cane has less glucose. The purity of the 

 diffusion juices was lower than that of the mill juices from the chips. 

 This is due probably to inversion in the battery. 



The column headed " extraction" in table 12 is given for the purpose 

 of noting to what extent, if any, the extraction was diminished by the 

 use of lime in the battery. If we compare the several instances of es- 

 pecially low extraction, Nos. 24G, 291, and 361, with the corresponding 

 acidity, we will note that either lime was in excess or the percentage of 

 sucrose for the day was high, without a corresponding change having 

 been made in working the battery, and in the amount drawn off. Octo- 

 ber 15, 



In mill juice there were 8.4 parts glucose to 100 parts sucrose 



In diffusion juice there were 16.5 parts glucose to 100 parts sucrose 



October 5 and 25, with acidity 9, the proportions in the two juices cor- 

 responded closely. 



The table shows, then, that the lime, unless in excess, did not inter- 

 fere with the extraction. 



Record was kept during the entire season of the amounts of sucrose 

 and glucose left in the chips. The highest percentage of sucrose in the 

 mill juices from these was noted at the end of the season, ^November 2, 

 being 2.91 per cent. The average extraction for the entire season was 

 88.72 per cent, of the sugar in the cane. This is a poor extraction, being 

 fully 4.1 percent, lower than the extraction at Fort Scott in 1887. The 

 average dilution for the season was 1 1.55 per cent. From the first of the 

 season to October 15, ICO gallons were drawn off' each time. From that 

 date till the close of the season 180 gallons. Each cell held 1,400 pounds 

 chips. Deducting 10 per cent, for fiber, we have 1,260 pounds juice in 

 each cell.

The poor extraction was due partly to the large chips furnished by 

 the small cutters during a portion of the season, to the irregularity in 

 working, but chiefly to the small quantity of juice drawn off; all points
