Analyses were also -made of canes grown in Indiana. 

 The canes were cut and prepared as follows : 4 



These canes were cut, the leaves and tops left undisturbed, the cut surface covered 

 with melted wax, and the whole wrapped carefully in paper and sent by express to 

 the laboratory here for analysis. 



Nos. 1 and 2 were cut in the afternoon of October 1 and analyzed October 4, having 

 been three days on the road. 



No. 1 was a sample of eight selected canes. No. 2 was a sample of sixteen canes 

 taken seriatim from an average row, and represents the cane as a whole. It seems to 

 have deteriorated very little in transit, and the analyses of the sirup go to show that 

 the average of the whole patch was about a mean of the results of Nos. 1 and 2. No. 3 

 was cut at 4 p. m. October 1 and analyzed October 6, at 9 a. m., an interval of four 

 days and seventeen hours.
