‘3 a It is at once apparent that the old method of calculating availa le ; % 
sugar must be abandoned. According to this rule there would be — 
 _- but 61.6 pounds available sugar per ton of cane in the diffusion juice _ 
TiN le 
of the first trial, when as a matter of fact 1304 pounds were obtained 
_ It would therefore seem that instead of preventing an equal weight — 
of cane sugar from crystallizing, the glucose and other solids not 
sugar in the juice prevented only two-fifths of their weight of cane 
pet - sugar from crystallizing. | This is also borne out by the data furnished 
_by the analysis of the juices during the entire season. — ae

a4 The above table discloses two very important facts: Vee 
it (1) The very uniform condition of the cane throughout the entire Wi 
es season. -

a the inversion of cane sugar is entirely prevented. ‘* tag i 
:: The amount of sugar left in the chips is larger than it ought to be. ~ 
: This is due, as previously stated, to the bad shape of some of the chips. - t; 
For this reason the juice was also more dilute, as larger charges had A nA 
to be drawn in order to get a more complete extraction. Up to Sep- iy 
tember 22 the amount drawn was 2,200 pounds.” From this to Octo- 
Barat ber 4, 2,640 pounds, and from October 4 to the end of the season 2,420 - ts
