Tlio cane continued to deteriorate, as is sliown in tlio folio win^;' 

 analyses of the juices from the mill of the Franklin Sugar Coinpaiiy : 



These discouraging effects of the severe frost of the Gth of October 

 did not afford any hope of successful continuation of the experiments. 

 It ^vill be quite impossible to work successfully a diffusion juice derived 

 from so poor a source. 



On October 12 an analysis of some samples of cane from a different 

 source showed that the juice had been little injured by the frost. The 

 numbers obtained were the followiDo:: 



Saorose.. 



Glucose 



Solids not sngar

Hoping that enough of such cane might be secured to allow of anofhcr 

 trial of the apparatus, it was determined to make another run on the 

 following day. The sample for analysis was taken from the west end 

 of a field, which was bordered on the west by a strip of forest and a 

 pond of water of considerable size. 



Evidently the spot whence the sample was taken had been protected 

 by these conditions from the action of the frost. Samples taken from 

 other parts of the field during the day, October 13, when the second run 

 was made, show, with the exception of the first one taken from the west 

 end of the field, a serious deterioration of the cane. Following are the 

 analyses of juices of canes expressed by experimental mill, made during 

 the day of October 13. 



Not only were the analyses sufiicient to show the injury that had been 

 done, but in addition to this the chips were soft and " bleeding," and 

 pcjssessed the odor characteristic of frozen cane. 



Work with such chips was more like maceration than diffusion ; never- 

 theless the run was made.
