COMPARISON OF SOEGHUM AXD MAIZE JUICES. 443 



Per Cent of Leaves and Stripped Stalks of Maize. 

 The relative amount of leaves and tops, as compared -with the strip- 

 ped stalks of maize, is as ihe average of several liundred stalks of 

 nine varieties: 59.8 per cent stripped stalks, 40.2 jier cent leaves and 

 tops. 



COMPARISON OF SORGHUM AND MAIZE JUICES. 



The following table has been prepared from the results of analyses, 

 made in 1880 and 1881, of 38 varieties of sorghum and 9 varieties of 

 maize, and comprise some thousands of analyses. 



The average results of the analyses of all those juices falling within 

 the specific gravities given are included, and we have those lietween 

 1014 and 1073 both for sorghum, of which there were, in 1881, 722 

 analyses made, and of maize, of which there were 202. So, too, in 

 1880, between specific gravity 1019 and. 1073, there were 2133 anal- 

 yses made of sorghum and 188 of maize juices. 



The analyses also are averaged of those juices between specific grav- 

 ity 1050 and 1070, of both sorghum and maize, for 1880 and 1881 ; 

 since these specific gravities include those juices generally worked from 

 syrup and sugar. 



There are also given the average results of those sorghum juices 

 which were of greater specific gravity than those of maize, viz.: In 

 1880, from 1070 to 1090; and in 1881, from 1070 to 1095. And, 

 finally, the general average for both years, of sorghum and maize 

 juices between 1019 and 1073, and between 1050 and 1070. 



Besides the average analyses of these juices, the per cents of availa- 

 ble sugar, total sugars, total solids, sucrose in total sugars, and in total 

 solids, is given. The table represents a very large number of anal- 

 yses, over 3,000, and a large number of varieties, 38 of sorghum and 

 9 of maize ; also the results of two seasons very unlike in climatic 

 conditions, as will be seen on page 148. This conclusion, therefore, 

 may be regarded as clearly established, which to many will appear 

 most surprising, viz.: In every case where two juices of the same s^ie- 

 eific gravity are taken, tlie one of sorghum and the other of maize 

 stalks, it will be found that, in every respect, that from maize is supe- 

 rior: First, iu the content of sugar; second, in the per cent of sucrose 

 in the total sugar, through a less quantity of glucose; and, third, in 

 the per cent of sucrose in the total solids. In other words, the maize 

 juice is the purer, and, by consulting the table, it will be seen that it 

 is very much more pure. For example : As the result of the analyses 

 of 1880 and 1881, the juices of maize, of specific gravity between 1050 

 and 1070, contained 12.11 per cent on an average of total sugars, and
