REPORT OF THE CHEMIST. 313 



About one-third of the cane received was partly stripped of its 

 blades. It appears from the above figures that the seed tops, blades, 

 and sheaths of the cane will amount to nearly 30 per cent, of the en- 

 tire weight. It must also be remembered that much of the blades, 

 sheaths, &c., was not removed by the very imperfect cleaning appar- 

 atus employed, and this weight is included in that of the ''clean 

 chips."

The cane used in the above experiments was stripped in the field. 

 The " cleanings" comprised the blades not removed and sheaths, &c., 

 blown out by the f anning-machine. Much of these impurities was 

 not removed. The sugar obtained was of a fair marketable kind and 

 found a ready sale. The molasses was of a dark color and a poor 

 quality. 



The weight of rnasse-cuite was determined on a portion of the prod- 

 uct by Mr. Swenson. He placed it at a mean of 12 per cent, of the 

 weight of the chips entering the battery. The weight of melada 

 obtained from the 2,322 tons was therefore 557,280 pounds, or 46,440 

 gallons. 



At the present writing (November 15) all of the sugar has not been 

 swung out, but the product will be about 50,000 pounds. This is in- 

 deed a discouraging yield, and quite in contrast with the phenomenal 

 quantity obtained from sugar-cane from Louisiana, to be mentioned 

 further along. If a proper crystallizing room had been provided by 

 the company the yield of sugar would have been much larger. On 

 November 2 the difiierent parts of the crystallizing room were found 

 to be of the following temperatures : 



Degrees F 



Northeast corner 84 



North center 84 



Three feet above floor, under north steam drum 72 



Northwest corner 75 



In upper layer of sirup in wagon, under south steam drum 105. 8 



Bottom of same wagon 77 



South center 79 



Southwest corner, over office 79 



Between steam drums 80. 1 



Temperature of air outside in shade 64. 4 



At such a low tem.perature a masse-cuite poor in sucrose and boiled 

 to string proof cannot crystallize to advantage. 



Before beginning the experiments with sugar-cane about to be de- 

 scribed I obtained permission of the company to provide a special hot- 

 room. With such material and with such unfavorable conditions of 

 crystallization the yield of over 20 pounds of sugar per ton is a con- 

 vincing proof of the efficiency of the process employed.
