time the first blossoms appear shows 23.06 per cent of crude 
protein (Nx6.25). Average wheat bran contains about 16 
per cent erude protein. On June 3rd, six days before harvest- 
ing the crop, the leaves contained 63 per cent of the total 
nitr’g.n of the part of the plant above ground. On June 
11th they contained 57 per cent, having lost 6 per cent be- 
cause of the transfer of nitrogenous material to the stem 
which was going on quite rapidly at this stage. This shows 
the great value of the leaves and emphasises the importance 
of preventing any loss of this material in harvesting and 
feeding the crop. The results of the analysis of the dry mat- 
ter of the leaves and stems, taken at the several periods, are 
given in table LX XI and reveal some interesting data.

It will be noticed that the percentage of dry matter in- 
creases quite regularly in both leaf and stem, being slightly 
higher at any given period in the leaf at every stage except
