Composition of Corn Stovkr. 



Water-free Materials. 



It is clearly shown by these analyses that the pith of this par- 

 ticular lot of stover, at least, did not ditfer in composition to a 

 remarkable degree from the remaining portion of the plant. It 

 contained about two-thirds as much nitrogenous material and 

 nearly twice as much ether extract, the proportions of fiber 

 (crude cellulose) and nitrogen-free extract, which together make 

 up the greater part of the stover, being very nearly the same as 

 in the other nine-tenths of the plant. This pith, instead of being 

 nearly pure cellulose, is at least two-thirds something else, and 

 there is no reason for supfposing that the pith of o^her lots of 

 maize would be essentially unlike this sample. 



It is interesting to know something of the character of the 

 nitrogen-free extract in maize pith, as compared with the other 

 tissue of the stover. Do the leaves and outside portion of the 

 stalk contain a larger proportion of sugars and starch and less 

 of those compounds concerning whose nutritive value we are less 

 definitely informed? Actual determinations answer this ques- 

 tion in the negative, so far as one lot of stover is concerned.
