342 grams of digestible matter, equal to 36.27 per cent, of the ex¬ 
tract; that of the native hay yielded 575 grams, equal to 32.79 per 
cent, of the extract; the residue or cellulose from the corn fodder 
yielded 1,210 grams of digestible matter, equal to 54 per cent, of the 
residue and that of the native hay yielded 1,502 grams, equal to 
50.57 per cent, of the residue. 
§218. In the case of the timothy hay, the values of the re¬ 
spective extracts stand in the same order, but the digestible matter 
furnished in each case, the sodic hydrate extract excepted, is less 
than in the two preceding cases; the alcoholic extract furnished 
1,085 gi'ams of digestible matter; the hydric chlorid extract 1,099 
grams; the sodic hydrate extract 733, and the residue of cellulose 
932 grams. The digestible proteids (N. x 6.25) in these extracts 
were determined; in the alcoholic extract there were 129 grams; in 
the hydric chlorid extract 23 grams, and in that obtained by means 
of sodic hydrate 136 grams. The digestible proteids in the corres¬ 
ponding extracts of the corn fodder were found to be 141 grams in 
the alcoholic, 28 grams in the hydric chlorid, and none in the sodic 
hydrate extract. We see again, in the timothy hay, as in the salt¬ 
bush, that a larger amount of proteids were digested and a decidedly 
smaller amount of carbohydrates, the most marked deficiency being 
in the portion designated as residue or cellulose. The feeding re¬ 
sults were a loss in both cases, though with the timothy hay, it was 
only slight, and one sheep showed a slight gain, but this sheep di¬ 
gested two-thirds more crude fibre than either of the other two. 
This may, however, be an accident only. The proteids in the vari¬ 
ous extracts of the native hay were not determined. 
§219. The extracts of the sorghum stand in the same order as 
those of the corn fodder, and the amount of digestible matter con¬ 
tained in the alcoholic extract is much larger, nearly twice as large, 
but that furnished by the hydric chlorid extract and by the residue or 
cellulose, furnishes one-sixth less than in the case of the corn 
fodder. 
§220. So far as our analytical results and also the energy 
values obtained are reliable criteria, sorghum fodder would appear 
to be a good one, but the results as indicated by the weights of the 
sheep at the beginning and end of this experiment indicate that it 
is a poor fodder. The results were uniform, i. e., each of the sheep 
lost three pounds and the conditions of the experiment were as fa¬ 
vorable as we could make them; everything, in fact, was in favor 
of obtaining good results with this fodder. The weather was fair 
and moderately cool. The sheep were used to being handled. They 
fed freely and were allowed a liberal ration, still they lost weight, 
and the same sheep gained when fed on corn fodder, so that the in¬ 
dividuality of the sheep is eliminated so far as this comparison of
