New York AGRICULTURAL EXPERIMENT STATION. 91 
DIGESTIBLE MATTER. 
On this point at this date it is impossible for us to give definite 
information since our experiments in this line are not yet 
completed. Two silos have been filled, one with B. & W. corn 
at watery stage of kernels, the other with King Philip corn 
fully ripe. Ata later date these will both be opened, the silage 
analyzed and digestion experiments made. A second lot of King 
Philip corn from same lot as put in silo was left for field curing 
and a third lot was put in barn-loft for curing. These will be 
carefully analyzed and their digestibility determined. When 
x 
_ these experiments are completed, we hope to have data which will 
more fully answer the question as to total available nutrients of 
the corns. : 
Artificial digestion serves to give us a pretty definite knowledge 
of the digestibility of the albuminoids of foods and by this means 
we find that for the several cuttings we have:

An inspection of the above table shows two periods of rapid 
increase in digestible albuminoids. These figures correspond 
- with the periods of similar increase in total albuminoids. Between 
the period of the corn silking and the kernels in milk there is 
almost no increase in albuminoids, and the same is true between 
the glazing and ripening period of the corn although a rapid 
- Increase of starch is made.

With the aid of Mr. Whalen, assistant chemist, Bulletin No. 17 
was prepared for publication, and as much careful labor was put 
upon the work, the Bulletin contains matter for reference worthy 
of a permanent place in the annual report, and is reproduced with 
few slight changes.
