SORGHUM. 



It is hardly possible to draw any definite conclu.sions from the above analj-- 

 ses, as many samples were not received for several weeks after being cut. It 

 will be seen, however, that nearly all those samples which were analyzed within 

 but a few days after being cut contain a large proportion of cane sugar, while 

 those which were analyzed after a longer period of time show a high content of 

 glucose and a low proportion of cane sugar. This corroborates my statement 

 in the first part of this report, and shows the necessity of working up the cane 

 directly from the field, in order to get the best results. 



It will also be seen, that all the samples conspicuous for their high content 

 of cane sugar are raised on a light soil, usually sandy loam, while tho.se raised 

 on heavy clay land contain large proportions of glucose. It, therefore, appears 

 that, in order to obtain a maximum content of cane sugar, the cane should be 

 grown on a light soil. For making syrup alone, the cane raised on clayey land 

 will do about as well, as the high content of glucose will not materially affect 

 the quality of the syrup. 



Twenty-six varieties of cane were grown on the university farm during the 

 past season, some of which were from seeds kindly sent by Dr. Collier. The 

 following table shows the results of my examinations:
