430 SORGHUM. 



Eticli of the above varieties were planted in i)lats having ten rows, 

 24 feet in each row, and the rows 3^ feet apart. There was, therefore, 

 of each variety planted -^^ of an acre, or 840 square feet. 



In the above list of the varieties, it will be seen that white and 

 yellow, flint and dent, common and sweet varieties, were included, so 

 that the results secured may be regarded as by no means exceptional. 

 Besides, these investigations were continued year after )'ear, with sev- 

 eral of these varieties, without any marked differences being mauifest 

 in the results obtained. 



The following table gives the several stages of development of the 

 plant, as mentioned in the tables of analyses, similar to those used in 

 the case of the sorghums. 



The ejcamination of sugar, or sweet corn, since the grain is used in 

 its immature condition, was continued Avith one portion of the plat 

 after the 11th stage, at which time the ears were removed. The stalks 

 were left standing in the field, and examined at intervals of one week 

 after the ears had been plucked. 



Stages of Development of Maize. 



Stage — 



1. About a week before the appearance of the tassel. 



3. Tassel just appearing 



5. Tassel entirely out. 



Y. Ear just appearing. 



9. Ear just forming grain. 



11. Ear in roasting condition. 



IH. One week after roasting condition. 



15. Two weeks after roasting condition. 



17. Three weeks after roasting condition. 



Intermediate stages were recorded in the observations, but the above 

 list is complete enough to enable the reader to understand the condition 

 of the plants when examined. 



The following table gives the average length and weight of the 

 several varieties of maize, as also the number of stalks of each from 

 which the averages were taken :
