TABLE III. Summary of average sample analyses, 1801 Continued. 

 (FOE AGE) RED LIBEEIAN. 



Early Orange falls very far below its usual average, being scarcely 

 better, except in purity, than the Bed Liberian field sorghum with which 

 it was grown. It is very probable that the intentional lack of care it ex- 

 perienced in planting and cultivation is mainly responsible, for while this 

 plat (A) was very badly injured by the season, yet it was from the same 

 stock as single head plat No. 1, and should have made nearly as good a 

 showing had its conditions of growth been comparable. The history of 

 this plat is suggestive, in view of the too common attempts which have 

 been made to raise fields of sorghum for sugar production without be- 

 stowing the care and attention which such a crop should have. 



The showing made by Collier's and Colman Cane in Table in is a long 

 step in advance of the progress hitherto made by any varieties tried upon 

 Calumet. Between August 10 and October 8 both these varieties main- 

 tained a sucrose content and purity which would almost have allowed 

 profitable working of the juice by ordinary sugar-house processes. 



In all varieties the nousugars are quite as high as in former seasons, 

 and it seems that any considerable breeding out of what is apparently 

 so fundamental a constituent of sorghum juices will prove possible, if 

 at all, only after years of intelligent and painstaking endeavor. 



Tables IV and V embody the outcome of the experiments of this and 

 the two preceding years ; from the varieties therein listed are selected 

 those upon which future culture will be principally centered as their 

 continued merit in the past gives them precedence over any other 

 varieties which may be introduced later. 



TABLE IV. Varieties, in order of merit, which have been noted in field and laboratory for 

 the various qualities named, during the experiments carried on in the season of 1S01 at
