and can be mowed by hand or machine easily, while the cow 
pea branches close to the ground and is harvested with diffi- 
culty. They can best be used as silage crops, and may be 
mixed with corn silage as the silo is being filled. According 
to our experience the medium green soy bean gives the largest 
yields of that fodder, while the Clay is one of the best varieties 
of the cow pea. Compared with corn fodder the yields of 
either the cow pea or soy bean are one-third to one-half less, 
while the percentage of protein is fully twice as much as in the 
corn. A silage of soy beans and corn gives a better balanced 
ration than corn alone, and seems to be well eaten by cows. 
COMPOSITION AND DIGESTIBILITY OF FEEDING STUFFS. 
Table 11, which follows, shows the average composition of a 
number of kinds of nitrogenous feeding stuffs ascommonly grown 
and sold in this region. ‘They may be divided into (1) coarse 
fodders, as clover hay, rowen hay, and oat and pea hay; and 
(2) concentrated feeding stuffs, as wheat bran, cotton seed meal, 
and other milling and by-products of the grains and seeds. 
For comparison are given the averages of analyses of several 
kinds of feeding stuffs low in nitrogenous matter (protein) 
such as corn silage, the hay of grasses, corn meal, etc. 
At the left of table 11 is given the average composition of 
our more common nitrogenous (protein) feeding stuffs. The 
figures are based in nearly all cases on the actual water con- 
tent of these materials as used for feeding or found for sale 
in the market. : 
At the right are given the percentages of protein, fat, and 
carbohydrates which are actually digested by the animals, as 
calculated by the use of the digestion factors given in the table 
of digestibility. These results are obtained by multiplying the 
percentage of nutrients as given on the left of table 11 by the 
coefficients of digestibility given in table 12. It will be noticed 
that the term carbohydrates is used in the right-hand columns 
under digestible nutrients, but does not appear in the left-hand 
side ofthe table. ‘The carbohydrates include the digestible nitro- 
gen-free extract and the digestible fiber. The digestible portions 
of these two materials have been found to be quite similar in 
feeding value, and hence they are included under one term (car- 
bohydrates) in stating the digestible composition of a fodder.
