AVERAGE KESULTS OF ANALYSES OF SOEGIIUM, ETC.

lu 1882, there were grown upon the grounds of the Department of 

 Agriculture, at Washington, 78 varieties of sorghum, cousisfiug 

 largely of varieties quite new to the Uuited States, from South Africa, 

 Chiua, and India. The Chinese varieties, and several of those from 

 Africa, proved to be comparatively worthless for sugar; but, since the 

 average results of the entire number grown and examined during the 

 season only serves to confirm fully the results already recorded as to 

 the gradual increase of sugar in these plants, the analyses are here 

 given :

Comparison unth Foreign Varieties. 

 In 1882, examinations were made of a large number of varieties 

 quite new to this country, from seed received from Africa, China, and 

 India, and the results of these analyses are given by themselves for 

 the purpose of comparison with the analyses of those varieties which 

 have been cultivated in the United States for the past thirty or thirty- 

 five years.
