If too much lime is added a dark sirup will be the result. If the lime is added very carefully, so as to make the juice very nearly neutral, an excellent sirup will be produced. The following rule for defecating juice for sirup works well: Fill the defecator three-fourths full with fresh juice; heat to about 160 F., and add milk of lime perfectly freed from coarse particles, until the juice becomes slightly alkaline. Fill the defecator with fresh juice, mix well and heat to boiling, skim and boil down to a sirup. The defecation may also be carried out as described under sugar making, a quantity of sulphurous acid being added to the defecated juice until it becomes slightly acid. If properly conducted this process will always make a good sirup. It is probably to be preferred to any other, as it is very easily performed. Not much care is requisite, as any small excess of sulphurous acid which has been added.will escape with the steam during the boiling down of the juice. Sulphate of aluminum may be used instead of sulphurous acid with equally good results, but more care is necessary, since any excess that is added will remain in the sirup. The flavor of the sirup will depend to a very great extent on the quantity of lime used for defecation, and the quantity to be added must be ascertained by practice. If the maker finds that the sirup still retains some of the " sorghum taste" it is a proof that too little lime has been used, and a stronger defecation should be made. If, on the other hand, the sirup is very dark, too much lime has been added. CONSUMPTION AND PBODUCTION. According to the late Commissioner o...
