Experience of Dr. C. A. Goessmann icitk Sorghum cut some time before 



Working. 



Dr. Goessmann, of the Massachusetts Agricultural College, in his 

 report of experiments upon the Early Amber Sorghum, gives a similar 

 series of results of analyses of juices entirely comparable "with those 

 just given. (Vide, report on " Early Amber Cane, by Profes.sor C A. 

 Goessmann, 1879.") His results are so valuable, as fully confirming 

 our own, and establishing the fact, that, what has been found true 

 during the past four years in this latitude, is equally true in Ma.«sachu- 

 setts — viz : that certain of the varieties of sorghum may, even in that 

 high latitude, attain a content of sugar fully equal to that of the sugar 

 cane of the tropics, that his analytical results of examination are here 

 appended. Of these, there -were but eighteen complete results ; and, 

 for purpose of comparison, the results here attained of the average of 

 juices having the same specific gravity as those analyzed by Dr. Goess- 

 mann, are given in the table alongside. It "will be observed that the 

 results attained by him, from August 15th to September 18th, in- 

 clusive, are almost identical with my own, showing, from the first, a 

 gradual increase in the sugar ;
