cient of digestibility for alfalfa as given by the New York and 
Colorado Stations, we have in the stem the following pro- 
portions: Digestible fat, .456 per cent; proteids,4.63 per cent; 
crude fiber, 25.00; nitrogen free extract, 20.21 per cent.,with a 
nutritive ratio of 1.10, requiring the addition of about 1.31 
per cent, of digestible proteids to make the nutritive ratio 
1 . /.8, W olff s standai cl latio for horses at moderate work. 
The stems used in the above analyses were very coarse for 
alfalfa stems, and the proportion of fine stems was small. I 
interpret the high percentage of crude fiber as indicating 
this, which I otherwise know to be a fact. The stems as 
selected by horses from the hay probably approach con¬ 
siderably neared to the ratio of an agreeable, sufficient, and 
advantageous ration than that deduced from the above 
analyses. The amide nitrogen is very low. 
LEAVES. 
The samples of leaves were carefully picked free from 
all stems. They were not free from the fungus, which 
causes the dark brown spots and which is described in the 
Third Annual Report of the Delaware Station, 1890, page 79, 
under the name of Pseudopeziza Medicagmis; also in New 
Jersey Report for 1889, pages 152-160, as Phacidium Medica- 
gims. This fungus was so prevalent at the time of gather¬ 
ing the leaves, that the avoidance of every affected leaf was 
practically impossible. The affected leaves were not suf¬ 
ficient in number to have any perceptible effect upon the re¬ 
sults. Analyses of affected leaves may be found in the New 
Jersey Report referred to above. Fresh leaves yield 68.72 
per cent, water and 31.28 per cent, air dried matter. The 
water is low, for one cannot pick them without their wilting 
somewhat.
