The proportion of cob to corn is probably considerably greater in the 

 immature state than when the corn has ripened, hence the real propor- 

 tionate value of the cob to the corn is probably greater at this period 

 than it is later. 



In whatever light these results may be viewed, it still seems that im- 

 mature corn-cobs have a decided food-value and can profitably be fed 

 to stock. By reference to the department report for 1878, p. 136, it will 

 be seen that the value of mature corn-cobs from field-corn, even when 

 " alkali extract " is included, is about 57 cents per hundred pounds, or 

 considerably less than the value of immature cobs from sweet corn ex- 

 clusive of alkali extract. 



In Table G the value of mature sweet corn is given at $1.49, a figure 

 nearly identical with those deduced for air-dry immatiu-e sweet corn. 



Analyses of Fultz wheat. 



The valuable constituents in these three samples are: 



1. Albuminoids, gluten and albumen. 



2. Fat, or oil. 



3. Carbhydrates, including sugars, gum, and starch, and starch-iso- 

 mers in the bran. 



Calculated cctiiparative food-values.

Bran ^° 



The somewhat prevalent idea that bran is the most valuable portion 

 of wheat is not substajitiated by these fig ures drawn from analyses. 



* Contains some nitroccnous matter soluble in water, ratlier more in Xo. 3 than in No. 1, and absent 

 In No-2 ; hence it must be derived ftom the bran.
