7 clover ; but with linseed meal it is easily understood since the 
nitrogen-free extract is quite different from that of other grains 
and approaches more nearly the mucilaginous and pectose bodies 
common in certain foods. Further study and experimenting, I 
am confident, will so perfect the method as to enable us to 
estimate in the laboratory the digestibility of the nitrogen-free 
extract of foods, as we now do for the albuminoids. 
WHEAT MIDDLINGS. 
Two samples of wheat middlings were received at the labora- 
tory from T. L. Cook. No. 1 was a fine. white product, nearly as 
light-colored as flour, and No. 2 was coarse and more bran with_a 
brownish hue. .Mr. Cookidesired to know, at the same price per 
ton, which would be the most valuable for growing and fattening 
pigs ? 7 
The following were the results of chemical analysis :

The two points specially worthy of note in the above results 
are the differences in per cent of ash and albuminoids. For 
young and growing animals or cows in full milk this is a very 
important consideration. For fattening full-grown, well-developed 
animals there seems to be difference of opinion. Probably much 
will depend upon the nature of the other foods to be fed in com- 
bination with the middlings, also on the environments of the 
animals themselves. 
A STUDY OF THE MAIZE PLANT. 
In 1888 some attention was given at this Station to investigating 
the increase and chemical changes which take place in the maize 
plant during its period of growth, and it was decided to continue 
the investigations through 1889.
