The mill used was Squeir's No. 2 Louisiana. 



The semi-sirup made amounted to 1,014 gallons, measured cold; spe- 

 cific gravity, 27^ B.= 1.225. One gallon, therefore, weighs 10.17 pounds j 

 total weight, 1,014 gallons =10,312 pounds. 



This semi-sirup was put in barrels and sent to Washington by freight. 

 It arrived there on October 25, and was immediately boiled in the vac- 

 uum-pan. 



The crystals were easily started in the pan, and grew to full size in 

 about ten hours. 



The melada was ready for the centrifugal as it came from the pan, 

 and some of it was swung directly from the pan, yielding 50 per cent, 

 of good sugar. 



I did not succeed in boiling to grain" ^ith any other sirup except 

 these two " strikes " from the Indiana cane. 



The weight of sugar obtained from the Indiana cane was 2,860 pounds. 

 This gives a percentage of 3.39 on clean cane ground and 6.09 per cent, 

 of the weight of j uice expressed. 



The result of the experiment with the Indiana cane was in every way 

 encouraging, and served in a manner to diminish the disappointment 

 which attended the work in other directions. 



A yield of over 60 pounds of sugar to the ton when only 50 per cent, 

 of the weight of cane was obtained in the expressed juice is an indica- 

 tion of what may be obtained in the future with better milling or a 

 more thorough extraction of the sugar by other methods. 



ALALYSES OF CANES, SIRUPS, AND SUGARS FROM INDIANA CANES. 



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. 



JS^os. 1 and 2 were cut in the afternoon of October 1 and analyzed 

 October 4, having been three days on the road. 



Xo. 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 semi-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 in- 

 terval of four days and seventeen hours. The results of this analysis 

 show that the cane had greatly deteriorated.
