horses, and it sells in the market at about one-half the price 
of native hay. 
It is not probable that chemical analyses will ever be 
able to discover these properties which are, partly at least, 
physiological ; still we may yet learn more about the subject 
and become able to form a better judgment than we can at 
present. 
In the following I have endeavored to obtain a better 
knowledge of the hays made from alfalfa, clover, the field 
pea, and native hay. 
For the methods followed I am indebted mostly to the 
work of Cross and Bevan, but I have also drawn upon what- 
ever literature has been accessible to me. 
The process of analysis is almost identical with that 
proposed by Professor Stone, i. e., successive extraction 
with boiling alcohol, cold water, diastase, boiling dilute acid, 
boiling dilute alkali, and treatment of the residual fiber 
with chlorin. The reducing power of the products of hy- 
drolysis were determined by means of Fehling’s solution 
and estimation of the copper by means of potassic cyanid 
solution. The chief difficulties arose from the large 
amounts of coloring compounds presents in some of the ex- 
tracts. The reducing power of some of these solutions was 
diminished by treating them with basic lead acetate, though 
I could find no sugar in the precipitate. 
The preparation of the sample of hay for this process is 
of considerable importance. If there are larger pieces of 
stems, it is difficult to free the cellulose from lignones and 
the cellulose will give the phloroglucin-hydrochloric acid 
reaction. I found this markedly the case with alfalfa, 
clover, and the pea vines, but not so with the native hay. If 
the sample is ground to a uniformly fine powder this is not 
the case, and the cellulose will not react with the phlo- 
roglucin solution. That this is the correct explanation of 
the cause of the reaction, and that it is not due to the ina- 
bility of the chlorin to remove the lignone groups, is clearly 
observable when the reaction is watched under the micro- 
scope. The small pieces will remain uncolored, and the 
large ones will be observed to have an outer uncolored por- 
tion inclosing a colored nucleus. 
The alfalfa selected for this analysis was a sample of 
new hay made from plants coming into bloom. 
The following are the results obtained :
