DETAILED ANALYSES OF STALKS OF SEVERAL VARIETIES, ETC. 435 



The following table gives, by stages, tlie average results of the anal- 

 yses of the twelve varieties examined. It will be observed that there 

 is a general resemblance to the results shown on page 194, of the ex- 

 amination of the sorghums — a gradual increase in specific gravity 

 of the juice and in the content of sugar; but an inspection of the 

 detailed analyses shows that this is nut as constant as with the sor- 

 ghums, and that the juice does not reach at any time the high content 

 of sugar which was found in the sorghum juices. 



But that this is often so high as to give reason for belief that even 

 cornstalks may be found a profitable source of sugar will appear, when 

 we consider that, of the analyses made of ten varieties of maize grown 

 in 1880, the juice gave, of crystallizable sugar, as follows: 



124 nn:ilyses of 10 varieties gave over 9 per cent. 

 90 analyses of 10 varieties g^ave over 10 per cent. 

 5.1 analyses of 9 varieties gave over 11 per cent. 

 24 analyses of 9 varieties gave over V2 per cent. 



8 analyses of 4 varieties gave over 13 per cent. 



2 analyses of 1 variety gave over 14 per cent. 

 1 analysis of 1 variety gave over 15 per cent. 



And of eight varieties grown in 1881, seven of which were common 

 field maize, 



3 analyses of ." varieties gave over 13 per cent. 



9 analyses of 7 varieties gave over 12 per cent. 

 21 analyses of 7 varieties gave over 11 per cent. 

 20 analyses of 7 varieties gave over 10 per cent. 

 So analyses of 7 varieties gave over 9 per eeuL
