the Plats A, B, and D, and upon samples from the row of forage sor- 

 ghum adjacent to A. The column headed " Solids " gives the degree 

 brix corrected for temperature; "Purity" expresses the per cent ratio 

 of sucrose to solids. The ratio of glucose to sucrose is not considered 

 of enough importance in this work to be calculated; in its stead is 

 given the ratio of nonsugars to sucrose. "Nonsugars" is the name 

 given to the juice-solids not sucrose or glucose, and, of course, is the nu- 

 merical difference between the per cent solids and the sum of sucrose 

 and glucose. 



Samples were uniformly of ten consecutive canes, and were taken at 

 weekly intervals, except in one or two cases.
