The samples taken September i6 were divided into stalk, 

 ear, husk, and leaves, and weighed, with the results given below : 



This table is not based upon enough weighings to be taken 

 as a standard, and is, in a measure, misleading, for example, the 

 Southern corn appears more leafy than any other variety, but the 

 thick base of the leaves encasing the stalk are much lonsrer in 

 this variety, and being very thick bring up the weight of the 

 leaves. This may be an advantage, or the reverse, according as 

 this part of the leaf is richer or poorer in nutriment, a question 

 which! find no information on. Chemical' anailysis would show 

 this, but this line of inquiry was, from necessity, left for future 

 investigation. 



In the case of the Sanford corn, I am of the opinion that 

 the proportion between the total weight and the weight of ear is 

 too small to represent a true average. 



In the case of the Northern field and Pride of the North 

 the ratio of ear to total weight is very nearly correct as was shown 

 by husking a part of the corn later. 



CHEMICAL COMPOSITION OF CROPS. 



The samples taken at the date above mentioned were anal- 

 ysed by Dr. .Burleigh, with the results given below : 



The increase of dry substance, which is the only part of 

 value as food, in the ordinary acceptation of ihe word food, is 

 exhibited in the following tabular form :
