THE DIPORTAXCX: OF A>' EVE^C CROP. ETC. 



60 



From the preceding table, it will be seen that, while the average 

 crop was the same from the suckered and unsuckered plats, and the 

 percentage of juice also practically the same, the composition of the 

 juice varied very widely, and, in every particular, was stronglv in 

 favor of the suckered stalks, so far as the production of sugar is con- 

 cerned. 



The average results of the thirty-four varieties show the relative 

 composition of juices to be as follows : 



Katio. 



Specifin gravitv percent 



Sii'^r-'Se " 



Gil. ose " 



Available sn<rar " 



Stripped stalks, jteracre pounds 



Juice per cent 



It will be seen that, although there is a much greater amount of 

 glucose and solids in the juice of the unsuckered canes, the specific 

 gravity is less, and the sucrose is a fifth less, while the available sugar 

 is only -15.7 percent of the amount present in the juice of the suckered 

 stalks. 



By reference to the table it will be seen, that several of the varieties 

 show no ditference between the suckered and unsuckered portions, while 

 in fact, some of them, as Xos. 1, 2, 18, show an amount of available 

 sugar greatest in the juice of the uusuckereil canes. The explanation 

 of this is probably that, owing to the fact that these varieties had so 

 long reached maturity, while the more advanced suckered canes had 

 begun t<> fall otf in their content of sugar, the unsuckered p<>rtions of 

 the cane were largely composed of suckers, which had themselves had 

 time to reach their complete maturity, and, consequently, they had 

 brought up the average of the juice, rather than to have lowered it. 



It is also to be observed, that, in the case of several of these varie- 

 ties, we have results fairly comparable with what might be expected 

 upon a large scale ; for, although, as has been already stated, the aual- 

 vses made during the season in the laboratory were of stalks taken from 

 the suckered portion of each variety, and although exactly one-sixth 

 part by actual weight, on an average, was taken from each variety, 

 and that, whenever a stalk was cut down there would springup suckers 

 in its place, which were included in the final cutting, generally, as we 

 have seen, with the effect to lower the average sugar content, it is yet true 

 that many of these, as we may term them, culled rows, gave averages
