ing to almost three pounds each while being fed on this sorghum 
fodder. 
§174. The amount of residue or cellulose digested in the vari¬ 
ous trials, the comparative uniformity of the coefficient of digestion 
and fuel value, indicate a very considerable food value for this por¬ 
tion of the fodder. It is the only portion of the saltbush that was 
not digested in the usual quantity. The general coefficient obtained 
for the crude fibre was only 8.29 in which is included the portion 
soluble in chlorin. When we consider the fuel value of this cellu¬ 
lose, it is higher, by a little, than that prepared from the other fod¬ 
ders, but the coefficient of digestion is very low, only 32.51 per 
cent. But it is higher than the coefficient found for the crude filDre 
of this hay, in fact it does not agree at all, except in that it is much 
lower than the coefficients which we found for this portion of the 
other fodders. The energy of the saltbush is, in general, low. The 
amount of water drunk was large and the animals were permitted 
to drink whenever they wished to. These two things may have 
interfered with the digestion of the cellulose, i. e., there may not 
have been enough energy available to effect its breaking up and to 
carry on the other bodily functions.
