22 MANUFACTURE OF TABLE SIRUPS FROM SUGAR CANE. 



the laboratory early in X()V(Miil)er, 1001, while the last .samples were 

 not reeeived until January, r.)()2. Samples were received from the 

 States of Alabama, Florida, (Georgia, and South Carolina. These 

 samples, on their reception at the laboratory, were immediately sub- 

 jected to analysis for the purpose of determinini^: the specific gravity, 

 sugar or sucrose, and reducing sugar or glucose, contained in the juices 

 thereof. From the data secured the coefficient of purity — that is, the 

 percentage of pure sucrose or sugar in the dry mattei- of the juice — 

 was calculated. 



The juices of sugar canes may bn said to comprise about W) per 

 cent of the total weight of the canes. Therefore the percentage of 

 the ingredients given in llie canes themselves would be, in round 

 numbers, 10 per cent less than in the juice. For instance, if the 

 sucrose or pure sugar in the cane juices amounted to 13.2 per cent, 

 the corresponding percentage of sugar in the cane would be 11.!) per 

 cent. 



The analytical data, w hich were determined chiefly l)y Mr. Arthur 

 Given, assisted by Mr. F. M. Cockrell, have been arranged al]3habet- 

 icalh'by States and counties, and are found in the table following.
